The antidepressant effect of intermittent theta burst stimulation (iTBS): study protocol for a randomized double-blind sham-controlled trial

BackgroundIntermittent theta burst stimulation (iTBS) when applied over the left dorsolateral prefrontal cortex (DLPFC) has been shown to be equally effective and safe to treat depression compared to traditional repetitive transcranial magnetic stimulation (rTMS) paradigms. This protocol describes a funded single-centre, double-blind, randomized placebo-controlled, clinical trial to investigate the antidepressive effects of iTBS and factors associated with an antidepressive response.MethodsIn this trial, outpatients (N = 96, aged 22–65 years) meeting the diagnostic criteria for at least moderate depression (Montgomery and Aasberg Depression Rating Scale score ≥ 20) will be enrolled prospectively and receive ten, once-a-day sessions of either active iTBS or sham iTBS to the left DLPFC, localized via a neuronavigation system. Participants may have any degree of treatment resistance. Prior to stimulation, participants will undergo a thorough safety screening and a brief diagnostic assessment, genetic analysis of brain-derived neurotropic factor, 5-HTTLPR and 5-HT1A, and cerebral MRI assessments. A selection of neuropsychological tests and questionnaires will be administered prior to stimulation and after ten stimulations. An additional follow-up will be conducted 4 weeks after the last stimulation. The first participant was enrolled on June 4, 2022. Study completion will be in December 2027. The project is approved by the Regional Ethical Committee of Medicine and Health Sciences, Northern Norway, project number 228765. The trial will be conducted according to Good Clinical Practice and published safety guidelines on rTMS treatment.DiscussionThe aims of the present trial are to investigate the antidepressive effect of a 10-session iTBS protocol on moderately depressed outpatients and to explore the factors that can explain the reduction in depressive symptoms after iTBS but also a poorer response to the treatment. In separate, but related work packages, the trial will assess how clinical, cognitive, brain imaging and genetic measures at baseline relate to the variability in the antidepressive effects of iTBS.Trial registrationClinicalTrials.gov NCT05516095.

Computer-aided cognitive training in patients with neurocognitive vascular impairment: effects on cognition, depression and behavior

Aim. The study evaluated the efficacy of computer-aided cognitive training program on cognitive measures, behavioral and depressive symptoms in persons suffering from Major Vascular Neurocognitive Disorder (vNCD).Methods. Retrospective study on a panel of 55 subjects with vNCD divided into a treatment group (n. 31) and a control group (n. 24) evaluated at baseline (T0) and at endpoint (T1) at 24 weeks. All subjects received the Mini Mental State Examination (MMSE), the Montgomery and Aasberg Depression Rating Scale (MADRS) and the Neuropsychiatric Inventory (NPI-P). The treatment group underwent a 24 weeks of computer-aided cognitive training. Results. Significant better performances of the treatment group were recorded at T1on MMSE. A significant reduction of behavioral disorders was shown by the treatment group as compared to the control group. No effect was observed on depression. Conclusions. Computer aided cognitive training showed positive effects on both behavioral and cognitive dimensions in persons suffering from vNCD.

The role of rehabilitation and vitamin D supplementation on motor and psychological outcomes in poststroke patients.

Post-Stroke depression affects between 12% and 72% of patients who have suffered a stroke. The association between low serum levels of 25-hydroxyvitamin D (25(OH) D) and increased risk of depression is reported in both stroke and non-stroke patients. Similarly, high 25(OH) D levels might be associated with greater functional improvement during rehabilitation program.We wanted to investigate the effects of an intensive rehabilitation on poststroke outcomes. We wondered if the daily rehabilitation of motor and cognitive functions could also have an effect on mood and functional abilities in addition to or as an alternative to vitamin D supplementation.We conducted a 12-week, randomized trial, double blind, parallel, monocentric clinical trial of 40 patients undergoing intensive neuro-rehabilitation treatment at a specialized care facility for ischemic or hemorrhagic brain stroke. Participants were randomly assigned, in a 1:1 ratio, to 1 of 2 parallel groups: in the experimental group, 2000 IU/day of oral cholecalciferol was administered; in the control group patients were not taking vitamin D supplementation. Patients underwent a text evaluation to investigate psychological and motor outcomes.Significant intra-group difference in outcomes measures was found but not between control group and experimental group. In the vitamin D group, we highlighted significant differences between T0 and T1 in calcium (P < .001), vitamin D (P < .001), in Montgomery Aasberg Depression Rating Scale (P = .001), and in Functional Independent Measures (P < .001). In the health control group, we found a significant difference in calcium (P = .003), vitamin D (P < .001), Montgomery Aasberg Depression Rating Scale (P = 0.006), in general self-efficacy (P = .009), and in Functional Independent Measures (P < .001).Our results show that the beneficial effect on mood and functional recovery is mainly due to neurorehabilitation rather than vitamin D supplementation.

Applicability of the locus of control of behaviour scale for people with dementia

Objective To investigate the applicability of the Locus of Control of Behaviour scale (LoCB) for people with dementia. Method A sample of 534 participants with dementia (78.4 mean age, 58% female) were included. Assessment included the LoCB, the Montgomery–Aasberg Depression Rating Scale (MADRS), the Mini-Mental Status Examination Norwegian revised (MMSE-NR) and the Instrumental Activities of Daily Living (I-ADL). Completion percentages and internal reliability of LoCB were examined for predefined MMSE-NR groups (0–4, 5–9, 10–14, 15–19, 20–24, 25–27, and 28–30). Factors associated with completion were analysed, and a principal component analysis (PCA) of the LoCB was performed. Sum score and component subscale scores were compared to MADRS and MMSE-NR scores. Results In total, 234 participants completed the LoCB. Completion percentages ranged from 74% (MMSE-NR 28–30) to 0% (MMSE-NR 0–9). Internal reliability was between 0.80 and 0.72 in groups with MMSE-NR > 9, except in MMSE-NR 20–24 (0.52). Age, MMSE-NR and education were associated with completion. The PCA yielded three components – powerful others, internal, and luck/fate – with explained variance of 41.3%. Participants with MADRS > 7 scored higher on the LoCB sum score, powerful others and internal subscale scores. No difference was found regarding the luck/fate subscale score. MMSE-NR did not affect LoCB scores. Conclusion Older age, less education, and more cognitive impairment decreased the likelihood of completion. However, psychometric test results indicate that those who completed the LoCB understood the questions, even with severe cognitive impairment. We conclude, therefore, that the LoCB is applicable for investigating control orientation among people with dementia.

Clinically relevant and simple immune system measure is related to symptom burden in bipolar disorder.

Immunological theories, particularly the sickness syndrome theory, may explain psychopathology in mood disorders. However, no clinical trials have investigated the association between overall immune system markers with a wide range of specific symptoms including potential gender differences. We included two similar clinical trials, the lithium treatment moderate-dose use study and clinical and health outcomes initiatives in comparative effectiveness for bipolar disorder study, enrolling 765 participants with bipolar disorder. At study entry, white blood cell (WBC) count was measured and psychopathology assessed with the Montgomery and Aasberg depression rating scale (MADRS). We performed analysis of variance and linear regression analyses to investigate the relationship between the deviation from the median WBC, and multinomial regression analysis between different WBC levels. All analyses were performed gender-specific and adjusted for age, body mass index, smoking, race, and somatic diseases. The overall MADRS score increased significantly for each 1.0×109/l deviation from the median WBC among 322 men (coefficient=1.10; 95% CI=0.32-1.89; p=0.006), but not among 443 women (coefficient=0.56; 95% CI=-0.19-1.31; p=0.14). Among men, WBC deviations were associated with increased severity of sadness, inner tension, reduced sleep, reduced appetite, concentration difficulties, inability to feel, and suicidal thoughts. Among women, WBC deviations were associated with increased severity of reduced appetite, concentration difficulties, lassitude, inability to feel, and pessimistic thoughts. Both higher and lower WBC levels were associated with increased severity of several specific symptoms. Immune system alterations were associated with increased severity of specific mood symptoms, particularly among men. Our results support the sickness syndrome theory, but furthermore emphasise the relevance to study immune suppression in bipolar disorder. Due to the explorative nature and cross-sectional design, future studies need to confirm these findings.

The natural history of depressive symptoms in patients with incident Parkinson's disease: a prospective cohort study.

Depression is common in patients with Parkinson disease and causes suffering and increased caregiver burden. A better understanding of depressive symptoms in Parkinson disease, their progression, and risk factors may, therefore, benefit management of these patients. The present study included 187 drug-naïve patients with incident PD and 166 controls from the population-based Norwegian ParkWest project. Depressive symptoms were examined with the Montgomery and Aasberg Depression Rating Scale (MADRS) at time of diagnosis and inclusion in the study and after 1, 3, 5, and 7 years of follow-up. Associations between MADRS scores and risk factors were assessed using generalized estimating equations (GEE). The mean MADRS score from all 823 examinations during the study period was 4.2 in patients and 1.3 in 732 examinations among controls. Among controls, the occurrence of depressive symptoms was also lower and rather stable during follow-up, while in patients, we observed a decrease from time of diagnosis and until the 1-year visit, followed by a steady increase in these symptoms over time. Factors associated with higher MADRS score in the multivariable model were female sex, being dependent, higher pain score, higher Unified PD Rating Scale (UPDRS) motor score, and lower Mini-Mental State Examination (MMSE) score. The results from this study underscore the importance and frequency of depressive symptoms in patients with early PD. Furthermore, risk factors that may be considered PD-nonspecific are associated with depressive symptoms as are factors that reflect the progression of PD.

The Relationships among Tryptophan, Kynurenine, Indoleamine 2,3-Dioxygenase, Depression, and Neuropsychological Performance.

It has been suggested that the metabolic enzyme indoleamine 2,3-dioxygenase (IDO) is a biological mediator of inflammation related to the psychopathology of depression, with a Kynurenine (KYN) increase in the Tryptophan (TRP) metabolic pathway, resulting in reduced Serotonin. In this study, we examined KYN, TRP, and the ratio of KYN to TRP concentrations × 103 (KT Ratio) in serum and cerebrospinal fluid (CSF) in (a) a group of depressed patients and (b) a control group of patients referred to a neurologic outpatient clinic for whom no specific diagnosis could be established. The KT Ratio is considered an index that represents IDO. The participants were examined with the Beck Depression Inventory II (BDI-II), the Montgomery Aasberg Depression Rating Scale (MADRS), and a neuropsychological test battery. We found no significant differences between the two study groups with respect to TRP, KYN, or KT Ratio in serum or CSF. Differences in neuropsychological performance between the two patient groups could be seen in the following tests: Animal Fluency, Digit Symbol, the DKEFS Color-Interference Test (Naming Part), Trail Making Test A and B, and the Grooved Pegboard Non-dominant Hand. KYN in serum correlated highly with KYN in CSF. KYN in serum correlated significantly with both age and gender. When analyzing males and females separately, we found that women had a lower level of TRP in both serum (Mann–Whitney U-test: TRP in Serum; p = 0.001) and CSF (Mann–Whitney U-test: TRP in CSF; p = 0.003). Women had a lower level of KYN in serum (p = 0.029) than men did. Age was positively associated with KYN. KYN in CSF correlated only with age, however; there were no gender differences. No significant relationship was seen between BDI-II and MADRS on the one hand, and KYN and TRP on the other. KYN in CSF as the KT Ratio in both serum and CSF was associated with neuropsychological performance. Thus, we suggest that KYN and KT Ratio are related more strongly to neuropsychological performance than to affective symptoms in depression.

Association between C-reactive protein (CRP) with depression symptom severity and specific depressive symptoms in major depression

IntroductionPopulation-based studies have associated inflammation, particularly higher C-reactive protein (CRP), with depressive severity, but clinical trials in major depressive disorder were rather non-specific without examining the role of gender. We aimed to investigate the association between CRP and overall depression severity including specific depressive symptoms and to examine potential gender differences. MethodsWe included 231 individuals with major depressive disorder from the Genome-Based Therapeutics Drugs for Depression (GENDEP) study. At baseline, we assessed high-sensitivity CRP levels and psychopathology with the Montgomery Aasberg Depression Rating Scale (MADRS). We performed linear regression analyses to investigate the association between baseline CRP levels with overall MADRS severity and specific symptoms at baseline and adjusted for age, gender, anti-inflammatory and psychotropic drug treatment, body mass index, smoking, inflammatory diseases, and recruitment center. ResultsHigher CRP levels were significantly associated with greater overall MADRS symptom severity (p=0.02), which was significant among women (p=0.02) but not among men (p=0.68). Among women, higher CRP was associated with increased severity on observed mood, cognitive symptoms, interest-activity, and suicidality, but we found no significant associations among men. Interaction analyses showed no significant gender differences on the overall MADRS score or specific symptoms. DiscussionOur results support the sickness syndrome theory suggesting that chronic low-grade inflammation may be associated with a subtype of depression. The potential gender differences in psychopathology may be explained by biological and/or psychosocial factors, e.g. differential modulation of immune responses by sex hormones. Clinical studies should investigate symptom-specific and/or gender-specific treatment guided by peripheral inflammatory markers.

The long-term development of non-motor problems after STN-DBS.

Stimulation of the subthalamic nucleus (STN-DBS) is an established treatment with long-term beneficial effects on motor symptoms in patients with Parkinson's disease (PD). The long-term development of non-motor problems after STN-DBS is not fully understood. In this study, we have studied how non-motor problems develop in patients with and without STN-DBS. We collected data from a prospectively followed cohort of patients that had been operated with STN-DBS 6-9 years before final examination and compared our findings to the longitudinal development of non-motor problems in a non-operated, comparable reference population. In general, the non-motor problems of advanced PD seem to develop independently of treatment with STN-DBS. We found that depressions do not worsen after STN-DBS, and the Montgomery and Aasberg Depression Rating Scale score in operated patients was substantially reduced from pre-operatively to post-operatively. Further, fatigue may represent an important unrecognized side effect of long-term stimulation, as fatigue was found to increase rapidly in operated patients already a year after surgery and continued to increase trough the 6- to 9-year follow-up. The non-motor problems of advanced PD seem to develop independently of treatment with STN-DBS. This may influence the strategy for choice of when to perform this therapy for eligible patients.

Vitamin D deficiency is common in psychogeriatric patients, independent of diagnosis.

BackgroundPrevious studies have found an association between psychiatric disorders and vitamin D deficiency, but most studies have focused on depression. This study aimed to establish the prevalence of vitamin D deficiency in elderly patients with a wider range of psychiatric diagnoses.MethodThe study included elderly patients (>64 years) referred to a psychiatric hospital in Northern Norway and a control group from a population survey in the same area. An assessment of psychiatric and cognitive symptoms and diagnoses was conducted using the Montgomery and Aasberg Depression Rating Scale, the Cornell Scale for Depression in Dementia, the Mini Mental State Examination, the Clockdrawing Test, and the Mini International Neuropsychiatric Interview (MINI+), as well as clinical interviews and a review of medical records. The patients’ mean level of 25-hydroxyvitamin D (25(OH)D) and the prevalence of vitamin D deficiency were compared with those of a control group, and a comparison of vitamin D deficiency across different diagnostic groups was also made. Vitamin D deficiency was defined as 25(OH)D <50 nmol/L (<20 ng/ml).ResultsThe mean levels of 25(OH)D in the patient group (n = 95) and the control group (n = 104) were 40.5 nmol/L and 65.9 nmol/L (p < 0.001), respectively. A high prevalence of vitamin D deficiency was found in the patient group compared with the control group (71.6% and 20.0%, respectively; p < 0.001). After adjusting for age, gender, season, body mass index, and smoking, vitamin D deficiency was still associated with patient status (OR: 12.95, CI (95%): 6.03-27.83, p < 0.001). No significant differences in the prevalence of vitamin D deficiency were found between patients with different categories of psychiatric diagnoses, such as depression, bipolar disorders, psychosis, and dementia.ConclusionVitamin D deficiency is very common among psychogeriatric patients, independent of diagnostic category. Even though the role of vitamin D in psychiatric disorders is still not clear, we suggest screening for vitamin D deficiency in this patient group due to the importance of vitamin D for overall health.

Zinc Deficiency Is Common in Several Psychiatric Disorders

BackgroundMounting evidence suggests a link between low zinc levels and depression. There is, however, little knowledge about zinc levels in older persons with other psychiatric diagnoses. Therefore, we explore the zinc status of elderly patients suffering from a wide range of psychiatric disorders.MethodsClinical data and blood samples for zinc analyzes were collected from 100 psychogeriatric patients over 64 of age. Psychiatric and cognitive symptoms were assessed using the Montgomery and Aasberg Depression Rating Scale, the Cornell Scale for Depression in Dementia, the Mini-Mental State Examination, the Clockdrawing Test, clinical interviews and a review of medical records. In addition, a diagnostic interview was conducted using the Mini International Neuropsychiatric Interview instrument. The prevalence of zinc deficiency in patients with depression was compared with the prevalence in patients without depression, and the prevalence in a control group of 882 older persons sampled from a population study.ResultsThere was a significant difference in zinc deficiency prevalence between the control group (14.4%) and the patient group (41.0%) (χ2 = 44.81, df = 1, p<0.001). In a logistic model with relevant predictors, zinc deficiency was positively associated with gender and with serum albumin level. The prevalence of zinc deficiency in the patient group was significantly higher in patients without depression (i.e. with other diagnoses) than in patients with depression as a main diagnosis or comorbid depression (χ2 = 4.36, df = 1, p = 0.037).ConclusionsZinc deficiency is quite common among psychogeriatric patients and appears to be even more prominent in patients suffering from other psychiatric disorders than depression.LimitationsThis study does not provide a clear answer as to whether the observed differences represent a causal relationship between zinc deficiency and psychiatric symptoms. The blood sample collection time points varied in both the control group and the patient group. No data regarding zinc supplementation were collected.

A cross-cultural comparison of the phenotype of depression as measured by the Cornell Scale and the MADRS in two elderly outpatient populations

Different cutoff points for a depressive disorder on depression scales exist in different countries. The reasons could be that the presence or the intensity of the various symptoms on the scales differ. We wanted to explore differences in scores on depression scales among patients in Brazil and Norway. The Cornell Scale for Depression in Dementia (CSDD) and the Montgomery-Aasberg Depression Rating Scale (MADRS) were completed independently among 211 elderly outpatients in Brazil and Norway. A psychiatrist, blind to the results, diagnosed depression using the ICD-10 and DSM-IV criteria. According to the ICD-10 criteria, 29 (33.7%) Brazilian and 51 (40.8%) Norwegian patients had depression (p=0.3). Mean CSDD score was 14.4 (SD 8.9) in Brazil and 6.8 (SD 4.9) in Norway (p<0.001). Mean MADRS score was 13.2 (SD 12.1) in Brazil and 8.4 (SD 6.8) in Norway (p=0.02). We analyzed the scores for the depressed and the non-depressed patients separately. In both groups the Brazilian patients had significantly higher scores on both scales compared to the Norwegian patients. In an adjusted linear regression analysis the variable "country" was associated with the CSDD score (beta=-0.29, p=0.01). The protocols in the two countries were not exactly the same. Only one psychiatrist evaluated the patients. The scores on the MADRS and the CSDD were higher in patients in Brazil than in Norway. In an adjusted linear regression analysis, "country" was the only variable associated with the higher CSDD score.

The validity of the Montgomery–Aasberg depression rating scale as a screening tool for depression in later life

The aims of the study were to examine the validity of the MADRS and to compare it with the validity of the Cornell Scale for Depression in Dementia (CSDD). We included 140 patients without dementia, with mean age 81.5 (sd 7.7) years. Trained psychiatric nurses interviewed all of them using the MADRS. In addition, for 70 patients caregivers were interviewed using the CSDD. A psychiatrist who had no access to the MADRS or the CSDD results made a diagnosis of depression according to the DSM-IV criteria for major depression, and the ICD-10 criteria was also applied for the 70 patients assessed with the CSDD. Twenty-two out of the 140 had depression according to the DSM IV criteria, whereas 25 out of 70 had depression according to the ICD-10 criteria. The area under the curve (auc) in a receiver operating characteristic analysis was 0.86 (95% CI 0.79-0.93) for the MADRS using the DSM-IV criteria. The best cut-off point was 16/17 with sensitivity of 0.80 and specificity of 0.82. The AUC for the CSDD was 0.83 (95% CI 0.71-0.95). The recommended cut-off score on the CSDD of 7/8 was valid but not the best in this study. The patients were diagnosed with a diagnosis of depression by only one psychiatrist, and the procedures in the two centres were not exactly the same. The MADRS has good discriminating power to detect depression in elderly persons and should be preferred to the CSDD for use with persons without dementia.

A psychometric evaluation of the Hospital Anxiety and Depression Scale for the medically hospitalized elderly

Background: Few psychometric studies of the Hospital Anxiety and Depression Scale (HADS) scale have been performed with clinical samples of elderly individuals. Methods: The participants were 484 elderly (65–101 years, 241 men) patients in an acute medical unit. The HADS, the Montgomery–Aasberg Depression Rating Scale (MADRS) and questionnaires assessing quality of life, functional impairment, and cognitive function were used. The psychometric evaluation of the HADS included the following analyses: 1) the internal construct validity by means of principal component analysis followed by an oblique rotation and corrected item–total correlation; 2) the internal consistency reliability by means of the alpha coefficient (Cronbach's) and 3) concurrent validity by means of Spearman's rho. Results: We found a two-factor solution explaining 45% of the variance. Six of seven items loaded adequately (≥0.40) on the HADS-A subscale (item 7 did not) and five of seven items loaded adequately on the HADS-D subscale (items 8 and 10 did not). Cronbach's alpha for the HADS-A and HADS-D subscale was 0.78 and 0.71, respectively. The correlation between HADS-D and the MADRS, a measure of the concurrent validity, was 0.51. Conclusion: The HADS appears to differentiate well between depression and anxiety. The internal consistency of the HADS in a sample of elderly persons was as satisfactory as it is in samples with younger persons. In contrast to younger samples, item 8 (“I feel as if I have slowed down”) did not load adequately on the HADS-D subscale. This may be attributed to the way elderly people experience and describe their symptoms.

Factor analysis of the Montgomery Aasberg depression rating scale in an elderly stroke population

Depression is frequent in elderly stroke patients, and the pathophysiology may involve psychological as well as organic mechanisms. To explore construct validity of the Montgomery Aasberg Depression Rating Scale using factor analysis and investigate whether symptom clusters of depression after stroke are associated with patient characteristics. A sample of 163 stroke patients was assessed by the Montgomery Aasberg Depression Rating Scale. Pre-stroke assessment was accomplished by means of the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE), the Barthel ADL Index and patient's medical history. Post-stroke assessment was performed with the Mini Mental State Examination (MMSE), the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), the Star Cancellation Test, the Barthel ADL Index, the modified Rankin Scale (mRS) and the National Institute of Health Stroke Scale (NIHSS). Information was collected from the patients' records. A principal components factor analysis followed by oblique rotation was performed. Among the patients, 56.4% scored between 7 and 19 on the Montgomery Aasberg Depression Rating Scale, and 13% had a score above 19. The factor analysis resulted in three factors, called anhedonia (lassitude, inability to feel, suicidal thoughts, loss of appetite), sadness (observed sadness, reported sadness, pessimism) and agitation (inner tension, lack of concentration, disturbed sleep). Anhedonia correlated with cognitive impairment, whereas sadness correlated with sensorimotor and cranial nerve deficits. Agitation had low internal reliability and did not correlate with any systematic patients characteristics. We found three distinct factors. The factor anhedonia is related to cognitive impairment, sadness to neurological impairment due to the stroke and agitation to somatic factors not directly related to the stroke.

Anxiety and depression in patients with self-reported food hypersensitivity

Objective Self-reported food hypersensitivity (SFH) is common. Psychological factors are assumed to be associated. We assessed anxiety and depression in SFH patients, using both questionnaires and interview. Methods Consecutive patients ( n=130) and randomly selected healthy volunteers ( n=75) completed the Hospital Anxiety and Depression Scale (HADS), the neuroticism scale of the Eysenck Personality Questionnaire (EPQ-N) and the General Health Questionnaire (GHQ). Seventy-six of the patients were also interviewed by use of the Mini International Neuropsychiatric Interview and the Montgomery–Aasberg Depression Rating Scale. All patients underwent extensive allergological, gastroenterological and dietary examinations. Results According to interviews, 57% of patients fulfilled the DSM-IV criteria for at least one psychiatric disorder. Anxiety disorders (34%) and depression (16%) predominated. According to questionnaires, patients scored significantly higher than controls on all psychometric scales except for depression (HADS). We also found an underreporting of depression in HADS compared with interviews (2.5% vs. 16%, P=.001). Food hypersensitivity was rarely confirmed by provocation tests (8%). Eighty-nine percent of the patients had irritable bowel syndrome. Conclusions Anxiety and depression are common in patients with IBS-like complaints self-attributed to food hypersensitivity. Anxiety disorders predominate. In this setting, depression may be underreported by HADS.

Hyperbaric oxygen therapy for late radiation tissue injury in gynaecological patients

Pelvic radiation therapy is an important element of curative therapy for gynaecological cancers. Serious radiation-related complications developing months or years after treatment are known as late radiation tissue injury (LRTI). We investigated the possible pain reducing effect of hyperbaric oxygen treatment (HBOT) in a study of 16 patients with LRTI after radiation for gynaecological malignancy. The 16 patients were registered prospectively, underwent HBOT for 21 consecutive days and were followed for a 6-month period after treatment using the Brief Pain Inventory, Montgomery and Aasberg Depression Rating Scale, as well as registration of global patient scores, analgesic consumption and magnetic resonance imaging (MRI) findings. HBOT was shown to have insignificant effect on pain, pain characteristics, daily function, the use of analgesics and MRI-related tissue injury. Fifty percent of the patients still reported some or good effect of the treatment. It is not possible to conclude from our study if gynaecological patients with pelvic pain will benefit from HBOT. The application of HBOT to selected patients may be justified, but further research with adequate sample size, as well as the timing of HBOT related to the development of LRTI, is required to establish the optimum patient selection.

Cognitive impairment in incident, untreated Parkinson disease

Little is known regarding the cognitive impairment in subjects with early, drug-naïve Parkinson disease (PD). The aim of this study was to explore the proportion with mild cognitive impairment (MCI) and subtypes in an incidence cohort of untreated PD in Southern and Western Norway. A total of 196 non-demented, drug-naive patients who were recruited after an extensive search of all new cases of PD in the area and 201 healthy control subjects completed a battery of neuropsychological tests of verbal memory, visuospatial, and attentional-executive functioning. Subjects were classified as MCI if the age- and education-corrected z-score was falling 1.5 standard deviations below the mean for at least one of the cognitive domains. The PD group was more impaired on all neuropsychological tests than controls, but the effect sizes were small. The largest effect size was found for verbal memory. A total of 18.9% of the patients with PD were classified as MCI, with a relative risk of 2.1 (1.2-3.6) in PD compared to the control group. Patients with PD with and without MCI did not differ significantly regarding demographic and motor features. Among PD-MCI patients, nearly two-thirds had a non-amnestic MCI subtype, and one third had an amnestic MCI subtype. The findings demonstrate a twofold increase in the proportion with cognitive impairment in subjects with early, untreated Parkinson disease (PD) compared to controls. This has implications for diagnosis and management of PD.

Predictors and course of health‐related quality of life in Parkinson's disease

We investigated how health related quality of life (HRQL) changes over time in a population-based cohort of patients with Parkinson's disease (PD), and which factors predict a lower level of HRQL in these patients. Of 227 patients with PD assessed at baseline and followed prospectively, information on HRQL-status was obtained in 111 subjects 4 years and 82 patients 8 years after inclusion. HRQL was measured by the Nottingham Health Profile (NHP). Analyses were conducted using generalized estimating equation models. The NHP total score (P < 0.001) and scores in all NHP dimensions except for sleep worsened significantly during follow-up. Steepest slope was found for the domain physical mobility (3.16, 95% CI 2.39-3.92), followed by the domains social isolation (2.22, 95% CI 1.52-2.93) and emotional reactions (1.36, 95% CI 0.74-1.97). In addition to follow-up time, higher Hoehn and Yahr staging, higher Montgomery and Aasberg Depression Rating Scale scores, and presence of insomnia at baseline were associated with lower levels of overall HRQL during follow-up. We conclude that PD has an increasing impact on HRQL as the disease progresses. During long-term follow-up, deterioration in physical mobility was the most important single factor contributing to decline in HRQL in our cohort, although distress of nonmotor character as a whole outweighed the impact of distress in physical mobility on overall HRQL. More advanced disease, higher severity of depressive symptoms, and presence of insomnia were found to be important and independent predictors of poor HRQL. (c) 2008 Movement Disorder Society.

“The Day the Music Died”

Background: The nursing home Valerengen bo– og servicesenter in Oslo, Norway, a long–term institution with 84 residents, has continually had regular music therapy activities with a music therapist in full–time employment since 1999. The institution was without music therapy services during the fall of 2003. Method: At the end of the period without a music therapist, measurement of depression level by the use of Montgomery Aasberg Depression Rating Scale (MADRS) was conducted on residents (n=72). Two months after music therapy services had been resumed with music therapy groups twice a week in each ward and individualized services other days, a new measurement of depression level of all residents was conducted. Results: Depression rating show a significant fall in the music therapy condition, compared with the no music therapy condition in a crossover design: MADRS 20.4 on an average in the no music condition, 12.2 on an average in the music condition (p < .05). Staff at the institution was stable, and there were no significant changes in medication. Conclusion: A significant reduction in the average level of depression in a nursing home when music therapy services are resumed warrants recommendation for a larger controlled follow–up study.
