Cognitive Behavioral Therapy for Depression and Anxiety in Parkinson's Disease: A Clinical Review

Parkinson's disease (PD) is the second most common neurodegenerative disorder. It is generally defined by its progressive motor features; but increased attention is being paid to its non-motor neuropsychiatric symptoms, which profoundly impact quality of life for patients and caregivers. Anxiety and depression are particularly problematic and are the strongest predictors of quality of life in PD. Recent research has focused on non-pharmacological approaches to treating depression and anxiety in patients with PD. Cognitive-behavioral therapy (CBT) is a potentially efficacious non-pharmacological treatment for mood and anxiety symptoms associated with PD. Accordingly, this review examines empirical studies of CBT-based treatments for depression and anxiety symptoms in PD. Medical Subject Headings were used in searches of PsychInfo and PubMed of English-language articles published in peer-reviewed journals, resulting in the identification of 10 articles. Four additional articles were identified from the references of these articles and upon the suggestions of experts, for 15 articles in all. Results of individual studies varied significantly; however, the randomized controlled trials showed encouraging results and support the need for further investigation of the utility of CBT for depressed and anxious patients with PD. CBT is potentially a useful treatment for patients with PD and comorbid depression and/or anxiety, but more systematic research will be necessary to measure its effects.

Quality of life and depressive symptoms in parkinson's disease after subthalamic deep brain stimulation. a 2-year follow-up study

To assess the correlation between quality of life (QoL), depressive symptoms and motor signs in patients with Parkinson disease after subthalamic deep brain stimulation (DBS STN). 74 patients, average age 55.6 ± 7 and duration of disease 12.3 years ± 3.8, treated with l STN DBS for PD were included in the study. All patients were evaluated with (UPDRS III), (PDQ-39) (BDI) at baseline and at 6, 12, and 24-month follow up. All patients were also stratified into three groups depending on UPDRS III improvement ( < 30%, 30-60%, > 60%). Scores in all scales significantly decreased from baseline. The improvement in PDQ-39 was 43.3%, in BDI 25.3 %; UPDRS-III 55.5% at 6 months. At 24 months, motor results and QoL deteriorated by 15.6% and 19.6% respectively. BDI remained unchanged. Mean scores at baseline in PDQ-39 were group I 67.4 ± 29.7; II 64.8 ± 32.0; III 53.4 ± 22.0 and for BDI, group I 17.4 ± 12.04; II 14.0 ± 9.7; III- 15.1 ± 10.55. Scores decreased significantly with DBS at 6-month follow-up and mean change was: PDQ-39, group I 42.7%, II- 40.7%, III 51.6%; BDI group I 23%, II 28.1%, III 23.3 %. Reduction of depressive symptoms, motor signs and improvement of QoL in PD after DBS STN are closely related. Improvement of QoL depends significantly on motor symptoms.

Neuropsychiatry of Parkinson's Disease

Parkinson's disease (PD) is traditionally regarded as a motor or a movement disorder. In recent years, however, an increased interest has been directed to its nonmotor symptoms as they seem to determine significant disability at all stages of the disease. Some PD patients consider their nonmotor symptoms even more disabling than motor signs. Among these nonmotor symptoms, neuropsychiatric syndromes (or behavioral and psychological symptoms) are of paramount importance. They include a wide array of syndromes such as anxiety, depression, psychosis, impulse control disorders, apathy, and cognitive dysfunction. Their pathogenesis in PD is rather complex, involving neurodegenerative, drug-related, and psychological mechanisms. Their recognition and management represent a great challenge. The paper by R. de la Fuente-Fernandez presents a staging model named PD-related frontostriatal cognitive dysfunction (PDFCD) that provides a clinical and hypothesis-testing framework for neuropsychiatric syndromes in PD. De La Fuente-Fernandez's PDFCD model proposes three stages based on the sequential process of dopamine depletion occurring in different regions of the striatum (stages I and II) and the frontal cortex (stage III). Therefore, PD patients would present executive dysfunction and mental fatigue (stage I), depression/anxiety (stage IIa), apathy/pain (stage IIb), and dementia (stage III). The paper by J. Calleo et al. summarizes the current literature on the cognitive rehabilitation programs in PD patients. Despite limited available data and heterogeneity of motor and nonmotor symptoms in PD, cognitive rehabilitation seems to be promising in this context. The paper by Y. Bogdanova and A. Cronin-Golomb1 presents an original study that assessed cognitive correlates of anxiety and apathy in PD patients. In comparison with matched controls, PD patients exhibited higher levels of anxiety and apathy which were correlated with disease duration. Interestingly, anxiety and apathy correlated differently with cognitive functions. The question remains open whether the treatment of both conditions impacts on cognitive functioning in PD. Until recently, most studies have focused on the impact of motor disability and depressive symptoms on the quality of life of PD patients, neglecting the role of anxiety. The paper by K. K. Hanna and A. Cronin-Golomb addressed this issue, reporting that anxiety, more than depressive, cognitive, and motor symptoms, significantly affected quality of life in PD. Dopaminergic strategies remain the mainstay of PD treatment. However, they are frequently associated with neuropsychiatric syndromes, notably psychosis. Alternative therapeutic options have been searched in the last years, and adenosine A2A receptor antagonists seem to be very promising. The paper by C. J. Bleickardt et al. demonstrates that, in comparison with dopamine receptor agonists, adenosine A2A antagonists exhibit better neuropsychiatric profiles as they do not interfere with prepulse inhibition in rodents (a model of psychosis). The paper by E. C. Lauterbach et al. presents a comprehensive review of the neuroprotective effects of the psychotropic drugs used in PD. Antonio L. Teixeira Leonardo F. Fontenelle Edward C.

Impact of anxiety on quality of life in Parkinson's disease.

In Parkinson's disease (PD), both the patient and the health care provider look for ways to preserve the patient's quality of life. Many studies focus on the impact of depression and motor disability on poor life quality but neglect to examine the role of anxiety. We investigated the impact of anxiety and depression on health-related quality of life in PD, using the Parkinson's Disease Quality of Life measure (PDQ-39). Symptoms of anxiety, more than depression, cognitive status, or motor stage, significantly affected quality of life in 38 nondemented patients with mild-to-moderate motor disability. Stepwise regression analyses revealed that anxiety explained 29% of the variance in the PDQ-39 sum score, and depression explained 10% of the variance beyond that accounted for by anxiety. The findings suggest that primary management of anxiety as well as depression may be important to optimizing the quality of life of PD patients.

Ocular motor and sensory function in Parkinson disease

Purpose: To evaluate the effect of dopaminergic medication or deep brain stimulation on ocular function in Parkinson disease (PD). To measure vision-related quality of life in PD.

On the nature of fear of falling in Parkinson's disease.

In the elderly, fear of falling (FoF) can lead to activity restriction and affect quality of life (QoL). Our aim was to identify the characteristics of FoF in Parkinson's disease and assess its impact on QoL. We assessed FoF in 130 patients with Parkinson’s disease (PD) on scales measuring perceived self-efficacy in performing a range of activities (FES), perceived consequences of falling (CoF), and activity avoidance (SAFFE). A significant difference was found in FoF between PD patients who had previously fallen and those who had not and between frequent and infrequent fallers. Patient-rated disability significantly influenced FoF. Difficulty in rising from a chair, difficulty turning, start hesitation, festination, loss of balance, and shuffling were the specific mobility problems which were associated with greater FoF in PD. Disability was the main predictor of FoF, additionally depression predicted perceived consequences of falling, while anxiety predicted activity avoidance. The FoF measures explained 65% of the variance of QoL in PD, highlighting the clinical importance of FoF. These results have implications for the clinical management of FoF in PD.

Quality of Life in Patients Suffering from Parkinson and #8217;s Disease and Multiple Sclerosis

Multiple sclerosis (MS) and Parkinson's disease (PD) are chronic diseases with unpredictable course causing progressive physical disability and cognitive decline, and broadly affecting the patient's life, social interaction, recreational activities and overall life satisfaction. To examine the quality of life of patients with PD and MS, and investigate the existence of differences between the degree of impairment to the quality of life in PD and MS. A prospective study was conducted at the Neurology Clinic, University Clinical Center in Tuzla in the period from December 2005 until May 2007. The study included subjects with confirmed diagnosis of MS and PD. We analyzed 50 patients with PD and 50 patients with MS, with disease duration 1-5 years without any or with mild cognitive impairment. Quality of life was assessed using the SF-36 scale comprised of 36 questions in eight health profiles. There was no significant difference in gender frequency in our study sample of patients with PD, while in MS group of patients there were a significantly more females. The average age of the PD patients was 63.18 +/- 10.42, and in patients with MS 37.4 +/- 8.65 years. In our study the relative influence of PD and MS on quality of life was similar after controlling the duration of the disease, and there were some differences in relation to the degree for clinical disability. Subjects showed reduced QoL independently of the duration of illness (patients with PD in 88% of cases, and multiple sclerosis in 84% of cases). There are significant differences in the occurrence of poor quality of life in patients with PD were in advanced clinical stages of disease for the physical, mental dimension of the SF 36 and the total score. Respondents in stages III-V of the disease were 5.23 times (23%) likely to experience reduced QoL compared to those with less physical disability. In subjects suffering from MS reduced QoL was not related to the degree of clinical disability in physical, nor the mental dimension of the SF 36 and the total score. These results in MS patients can be partially explained by the small sample size, on the other hand it is possible that patients with MS, although they have greater physical disability seen as a very difficult diagnosis which determines the entire life. Patients who are treated for PD and MS had a high degree (> 80%) of reduction of the overall quality of life, and there were no significant differences in the extent of QoL reduction between these groups of patients. Reduced quality of life in patients with PD is observed during severe stages of the disease, while the QoL does not depent on the degree of clinical disability in MS patients. In both groups of patients the appearance patients reduced QoL does not depend on the duration of the disease.

Boxing Training for Patients With Parkinson Disease: A Case Series

A nontraditional form of exercise recently applied for patients with Parkinson disease (PD) is boxing training. The primary purpose of this case series is to describe the effects of disease severity and duration of boxing training (short term and long term) on changes in balance, mobility, and quality of life for patients with mild or moderate to severe PD. The feasibility and safety of the boxing training program also were assessed. Six patients with idiopathic PD attended 24 to 36 boxing training sessions for 12 weeks, with the option of continuing the training for an additional 24 weeks (a seventh patient attended sessions for only 4 weeks). The 90-minute sessions included boxing drills and traditional stretching, strengthening, and endurance exercises. Outcomes were tested at the baseline and after 12, 24, and 36 weeks of boxing sessions (12-, 24-, and 36-week tests). The outcome measures were the Functional Reach Test, Berg Balance Scale, Activities-specific Balance Confidence Scale, Timed "Up & Go" Test, Six-Minute Walk Test, gait speed, cadence, stride length, step width, activities of daily living and motor examination subscales of the Unified Parkinson Disease Rating Scale, and Parkinson Disease Quality of Life Scale. Six patients completed all phases of the case series, showed improvements on at least 5 of the 12 outcome measures over the baseline at the 12-week test, and showed continued improvements at the 24- and 36-week tests. Patients with mild PD typically showed improvements earlier than those with moderate to severe PD. Despite the progressive nature of PD, the patients in this case series showed short-term and long-term improvements in balance, gait, activities of daily living, and quality of life after the boxing training program. A longer duration of training was necessary for patients with moderate to severe PD to show maximal training outcomes. The boxing training program was feasible and safe for these patients with PD.

Neuropsychological correlates of mild to severe hallucinations in Parkinson's disease

The development of visual hallucinations (VH) is a frequent complication of Parkinson's disease (PD). Presence of hallucinations is one of the main risk factors associated with dementia, and severity progression of VH mainly contributes to impaired quality of life in PD. The neuropsychological features associated with severity progression of VH are unknown and might help to detect patients at risk of a more severe outcome. We aimed to explore the neuropsychological deficits associated with the different types of VH observed in PD, from minor hallucinations to well-formed VH with loss of insight. Prospective study of 57 PD patients with (n = 29) and without VH (n = 28) matched for age, education, antiparkinsonian medications, and disease duration. Description of VH was assessed by the Hallucinations and Psychosis item of the MDS-UPDRS. Cognition was assessed with the Parkinson's Disease-Cognitive Rating Scale (PD-CRS) and the Mattis Dementia Rating Scale (MDRS). Patients with minor VH did not differ from patients without VH in any cognitive domain. PD patients with major VH and insight retained performed worse on the action verbal fluency task (P < 0.04), and patients with VH and loss of insight showed a greater impairment on the PD-CRS posterior cortical score (P = 0.021) and the clock copying item (P = 0.01). A double dissociation was found in the neuropsychological profile of patients with VH with and without loss of insight. While the presence of major VH with insight retained appeared related to a predominant frontal-striatal impairment, loss of insight was characterized by further impairment of cognitive functions related to posterior cortical areas. A comprehensible continuum pattern of clinical relationships emerged among VH and cognitive functioning in PD.

Fatigue in Japanese patients with Parkinson's disease: A study using Parkinson fatigue scale

The objective of this multicenter cross-sectional study was to determine the prevalence of fatigue and factors contributing to it in a large sample of Japanese patients with Parkinson's disease (PD). We used the 16-item Parkinson Fatigue Scale (PFS-16), which was designed to assess fatigue exclusively associated with PD. We carried out this study using PFS-16, the Unified Parkinson's Disease Rating Scale, Zung's Self-Rating Depression Scale, Parkinson's Disease Sleep Scale (PDSS), and the PD quality of life (QOL) scale (PDQ-39) by interview using questionnaires and physical examination by neurologists in 361 nondemented PD patients. Fatigue (an average PFS score of 3.3 or greater) was revealed in 151 patients (41.8%). Multiple logistic regression analysis indicated that the significant independent variables related to the presence of fatigue were the scores of PDSS and PDQ-39. Depression score was not a significant contributing factor. Our study revealed that the prevalence of fatigue in Japanese PD patients is as high as that in Western countries, and that fatigue is a relatively independent symptom, although sleep disturbance may be associated with fatigue. Since fatigue is significantly related to QOL reduction, therapeutic interventions including treatment of sleep disturbance are important.

Eighteen month study of continuous intraduodenal levodopa infusion in patients with advanced Parkinson's disease: Impact on control of fluctuations and quality of life

Symptom control, daily “on” time, and quality of life (QoL) of nine patients with Advanced Parkinson's Disease was assessed following 18-months treatment with Continuous Intraduodenal Levodopa Infusion (CIDLI). Patients had severe motor fluctuations and dyskinesias and had previously received treatment with oral levodopa and dopamine agonists. There were significant improvements in patients' symptoms on the Unified Parkinson's Disease Rating Scale, and QoL (Parkinson's Disease QoL Questionnaire; Schwab & England Capacity for Daily Living Scale; p < 0.05). Mean (±SD) daily “on” time increased from 6.1 ± 1.9 to 12.0 ± 3.4 h ( p < 0.05). Improved QoL in APD was associated with CIDLI-related improvements in symptom control and increase in daily “on” time.

Exercise therapy, quality of life, and activities of daily living in patients with Parkinson disease: a small scale quasi-randomised trial

BackgroundThe purpose of this study was to examine the effect of a 10-week exercise therapy regimen on activities of daily living (ADL) and perceived health status in patients with Parkinson disease.MethodsTwenty-four Parkinson's disease patients entered into the study. Participants were allocated into the experimental (n = 12) or control group (n = 12). ADL was assessed using the Short Parkinson Evaluation Scale/Scale for Outcomes in Parkinson Disease (SPES/SCOPA) and perceived health status was measured using the Parkinson's Disease Quality of Life (PDQL) questionnaire. Patients in the experimental group received pharmacological therapy plus a 1-hour exercise therapy session 4 times a week, while patients in the control group received pharmacological therapy only. The Mann-Whitney U test was used for comparison.ResultsThe mean age of participants was 59.8 (SD = 3.0) and 58.2 (SD = 3.4) years in the experimental and control groups, respectively. The median Hoehn and Yahr stage was 3.0 for both groups. There were no significant differences in all subscales and overall scores between two groups at baseline. However, after the intervention, except for the emotional functioning (P = 0.27), there were significant differences between the two groups for Parkinson symptoms, systemic symptoms, social functioning, and overall scores of the PDQL (all P values < 0.05), and the ADL (P = 0.01) indicating that quality of life was improved in the experimental group.ConclusionThe findings from this small scale quasi-randomised trial showed that exercise therapy was effective in improving activities of daily living and perceived health status in patients with Parkinson's disease. Indeed, exercise therapy could be offered to patients with Parkinson disease, considering that it is low in cost and usually has no negative side effects.Trial registrationCurrent Controlled Trials ISRCTN98825027

Quality of life in Serbian patients with Parkinson’s disease

The Parkinson's Disease Questionnaire (PDQ-39) is a well-validated British scale for the assessment of health-related quality of life (QoL) in Parkinson's disease (PD). To validate the Serbian version of the PDQ-39, while also providing additional information on the characteristics of this instrument. A total of 102 Serbian PD patients were asked to complete the PDQ-39, a disease-specific QoL questionnaire, as well as the generic, health status questionnaire (SF-36-version 1), and the 21-item Beck Depression Inventory. Neurological examination included the Hoehn and Yahr staging, Unified Parkinson's disease rating scale (UPDRS)-part III, Schwab and England scale, and the Mini-Mental State Examination. Internal consistency analysis yielded a Cronbach's alpha of 0.83. Cronbach's alpha was above 0.70 for seven out of eight subscales (range from 0.73 to 0.91). A hierarchical structure of the PDQ-39 was revealed, with one global higher-order factor and two lower-order factors. The strongest predictor of the QoL in PD was the presence of depression, while motor disability (UPDRS-part III score) additionally contributed to poor QoL. Cognitive impairment has not been correlated with poor QoL. Also, QoL measures were not different between young- (< or =50 years) and older-onset PD patients. The PDQ-39 is a reliable and valid instrument for the assessment of QoL in Serbian PD patients.

Depressive symptoms and perception of quality of life in Parkinson's disease

Depression has been proposed as a major contributor to poor quality of life (QoL) in Parkinson's disease (PD). To evaluate the relationship between depressive symptoms and QoL in subjects with PD. Beck Depression Inventary (BDI) was used to evaluate depressive symptoms and Parkinson's Disease Quality of Life Questionnaire (PDQ-39) to assess the perception of the QoL. Thirty seven patients (19 male/ 18 female) with a typical onset PD and mean disease duration of 7.7 years were studied. Higher scores on BDI correlated with poorer perception of the QoL. This association occurred at the expense of the following PDQ39 domains: mobility, activities of daily living, social support, cognition and emotional well-being dimensions. PD severity also correlated with QoL. Our study corroborates the assumption that depressive symptoms contributed significantly to QoL in PD.

Intrajejunal levodopa infusion in Parkinson's disease: A pilot multicenter study of effects on nonmotor symptoms and quality of life

Switching from oral medications to continuous infusion of levodopa/carbidopa gel reduces motor complications in advanced Parkinson's disease (PD), but effects on nonmotor symptoms (NMSs) are unknown. In this prospective open-label observational study, we report the effects of intrajejunal levodopa/carbidopa gel infusion on NMS in PD based on standard assessments utilizing the nonmotor symptoms scale (NMSS) along with the unified Parkinson's disease rating scale (UPDRS 3 motor and 4 complications) and quality of life (QoL) using the Parkinson's disease questionnaire (PDQ-8). Twenty-two advanced PD patients (mean age 58.6 years, duration of disease 15.3 years) were followed for 6 months. A statistically significant beneficial effect was shown in six of the nine domains of the NMSS: cardiovascular, sleep/fatigue, attention/memory, gastrointestinal, urinary, and miscellaneous (including pain and dribbling) and for the total score of this scale (NMSST) paralleling improvement of motor symptoms (UPDRS 3 motor and 4 complications in "best on" state) and dyskinesias/motor fluctuations. In addition, significant improvements were found using the Parkinson's disease sleep scale (PDSS) and the PDQ-8 (QoL). The improvement in PDQ-8 scores correlated highly significantly with the changes in NMSST, whereas a moderately strong correlation was observed with UPDRS changes. This is the first demonstration that a levodopa-based continuous dopaminergic stimulation is beneficial for NMS and health-related quality of life in PD in addition to the reduction of motor fluctuations and dyskinesias.

The Effect of Duloxetine on Primary Pain Symptoms in Parkinson Disease

To study the effect of duloxetine (Cymbalta), a selective serotonin and norepinephrine reuptake inhibitor, on pain symptoms in Parkinson Disease (PD). Twenty-three patients with PD with painful phenomena were treated with duloxetine for 6 weeks in an open-label design. Assessments were performed before and at treatment completion and consisted of a Visual Analogue Scale, the Brief Pain Inventory, Short-Form McGill Pain Questionnaire, Parkinson Disease Quality of Life Questionnaire-39-item version, and motor part of the Unified Parkinson Disease Rating Scale. Pain threshold was assessed by quantitative sensory tests. Thirteen of the 20 patients who completed the study reported varying degrees of pain relief. The mean Visual Analogue Scale, Brief Pain Inventory, and Short-Form McGill Pain Questionnaire scores decreased significantly. There was no change in pain threshold after treatment. Duloxetine seems to be effective for the treatment of central pain in PD.

Cognitive Change in Parkinson Disease

Parkinson disease (PD) is the most common neurodegenerative movement disorder, affecting 1 in 100 individuals over the age of 60. Dementia in the setting of PD (PDD) may be among the most debilitating symptoms associated with disease progression. Estimates of cognitive decline and dementia in PD suggest that up to 14% per year of patients over age 65 with PD will develop some cognitive impairment. Unfortunately, PDD is not well characterized and the relationship of PDD to Alzheimer disease remains unclear. PDD has been proposed as part of a spectrum with dementia with Lewy bodies, and PDD and dementia with Lewy bodies frequently coexist with Alzheimer disease. It is uncertain, however, whether there is a meaningful distinction between the different disorders. It has also been difficult to gain understanding of the interaction of motor and non-motor symptoms that affect quality of life in PD and confound cognitive and psychomotor performance. This review will examine the clinical, cognitive, neuropsychiatric features of cognitive deficits associated with PD, discuss their pathologic basis and propose avenues for future research.

Effects of dyskinesias in Parkinson's disease on quality of life and health‐related costs: a prospective European study

The treatment of Parkinson's disease (PD) with l-DOPA leads to involuntary movements (dyskinesias). This 6-month observational study in three European countries in PD patients with various degrees of motor complications examined the effects of dyskinesias on the quality of life (QoL) of patients and health care costs. Retrospective and prospective health economic data were collected, and QoL of patients was measured using the Short Form-36 (SF-36) and the PD Quality of Life (PDQL) Scale. Regression analysis was used to estimate the adjusted effects of dyskinesias on QoL and costs, whilst accounting for the potentially confounding effects of disease progression, motor fluctuations and country. Increasing dyskinesia scores on either the Unified PD Rating Scale or the Goetz Dyskinesia Rating Scale were associated with significant reductions in QoL scores on the SF-36 and PDQL Scale. Increasing dyskinesia severity was also associated with increased depression scores on the Montgomery-Asberg Depression Rating Scale along with significant increases in health care costs. The effects of dyskinesia on QoL, depression and costs decreased but remained significant after adjustment for the confounding effects of disease progression and motor fluctuations. In conclusion, dyskinesias may adversely affect QoL and increase health care costs in patients with PD. Future studies should evaluate the potentially beneficial effects in terms of QoL and health care costs of strategies to delay the onset of, or the treatment of, dyskinesias.

Uso de escalas para avaliação da doença de Parkinson em fisioterapia

A Doenca de Parkinson (DP) e uma enfermidade degenerativa do sistema nervoso central cujas caracteristicas sao tremor, rigidez e bradicinesia. Com o progresso terapeutico, desenvolveram-se varias escalas visando monitorar a evolucao da doenca e a eficacia de tratamentos. O objetivo desta revisao foi caracterizar as principais escalas usadas para avaliacao da DP, discutindo sua aplicabilidade a pratica fisioterapeutica. As escalas encontradas na literatura foram: a de estagios de incapacidade de Hoehn e Yahr; a Escala Unificada de Avaliacao da DP (UPDRS); a escala de Webster de avaliacao da DP; a escala de Sydney; a Escala de Incapacidade da Northwestern University (NUDS); os questionarios da DP (PDQ-39) e de Qualidade de Vida na DP(PDQL); e a Escala de Atividade de Parkinson (PAS). A Webster permite classificar o paciente de acordo com seu nivel de incapacidade, porem nao ha estudos conclusivos quanto a sua confiabilidade. A Sydney avalia o nivel da estrutura e funcao corporal, enquanto o enfoque da NUDS e nas atividades funcionais diarias. O PDQ-39 e o PDQL sao questionarios especificos para avaliar a percepcao do paciente sobre sua qualidade de vida. Sobre a PAS, desenvolvida recentemente com base em objetivos da fisioterapia, nao ha estudos suficientes para definir sua confiabilidade. Destacam-se as escalas de Hoehn e Yahr e a UPDRS, por sua confiabilidade, podendo ser usadas por fisioterapeutas para melhor avaliacao do estado clinico-funcional do paciente.

Only physical aspects of quality of life are significantly improved by bilateral subthalamic stimulation in Parkinson’s disease

The well known global improvement of quality of life (QoL) after bilateral high frequency chronic deep brain stimulation of the subthalamic nucleus (STN DBS) in Parkinson's disease (PD) is in contrast to behavioral disturbances as observed after surgery. Indeed the impact of DBS on physical versus mental aspects of QoL in PD remains unknown. To assess the influence of bilateral STN DBS on physical versus mental aspects of QoL in Parkinson's disease. The results of 27 patients for the Unified Parkinson's disease Rating Scale (UPDRS), Parkinson's Disease Questionnaire 39 (PDQ39) and Short Form 36 health survey questionnaire (SF36) were compared before surgery and after 12 months of bilateral STN DBS. Comparing off-dopa conditions before versus 12 months after surgery, both UPDRS part II and part III significantly improved: 32.6% and 52%, respectively. UPDRS part I scores did not change significantly at 12 months. As for PDQ39, the global score significantly improved after surgery (21.1 %) as did four subscores: mobility (25.6 %), activity of daily living (34.5 %), stigma (40.1 %) and bodily discomfort (30 %). Three PDQ39 subscores, however, showed no significant changes: emotional well-being (10.7 %), social support (3.2%) and cognition (8.5 %) and one item even worsened: communication (-7.7 %). In SF36, only physical items significantly improved. Using clinician's based rating scale, bilateral STN DBS showed significant improvement in PD patients at 12 month follow up. However, using patient's self-assessment scales, the clinical benefit of STN DBS was more subtle: physical items of QoL significantly improved, whereas mental items such as emotional well-being, social support, cognition and communication showed no improvement. Our results are suggestive of a dissociation of motor and non-motor symptoms control after bilateral STN DBS in PD patients.
