Neuropsychiatric Symptoms In Adults Research Articles

Cognitive impairment and neuropsychiatric symptoms among individuals with history of symptomatic SARS-CoV-2 infection: a retrospective longitudinal study.

To identify the main cognitive and neuropsychiatric symptoms in adults who had no cognitive complaints prior to the infection. Specifically, to observe the trajectory of cognitive and neuropsychiatric performance after 6 months. This is a retrospective longitudinal study. Forty-nine patients (29 reassessed after 6 months), with a positive PCR test, with no prior cognitive complaints that only presented after the infection and without a history of structural, neurodegenerative or psychiatric neurological diseases. A brief cognitive assessment battery (MoCA), the Trail Making Test (TMT-A, B, ∆), and the Verbal Fluency Test were used, as well as the scales (Hospital Anxiety and Depression Scale-HADS, Fatigue Severity Scale-FSS). Correlation tests and group comparison were used for descriptive and inferential statistics. Level of significance of α=5%. Mean age of 50.4 (11.3), 12.7 (2.8) years of education, higher percentage of women (69.8%). No psycho-emotional improvement (depression and anxiety) was observed between the evaluations, and patients maintained the subjective complaint of cognitive changes. The HAD-Anxiety scale showed a significant correlation with TMT-B errors. The subgroup participating in cognitive stimulation and psychoeducation showed improvement in the global cognition measure and the executive attention test. Our results corroborate other studies that found that cognitive dysfunctions in post-COVID-19 patients can persist for months after disease remission, as well as psycho-emotional symptoms, even in individuals with mild infection. Future studies, with an increase in casuistry and control samples, are necessary for greater evidence of these results.

[Top 5 Research Studies of the month for Italian Primary Care Physicians: October 2023.]

This monthly article provides a selection of summaries of the most relevant studies identified as POEMs (patient-oriented evidence that matters) for Italian primary care physicians. Amoxicillin is no more likely to cause a rash than any other antibiotic in children with infectious mononucleosis. According to a good quality systematic review and network meta-analysis, only a small number of randomized controlled trials, disappointing in overall quality, suggest that for managing neuropsychiatric symptoms in adults with dementia, risperidone has the best balance of effectiveness and adverse effects. In a rigorously conducted double-blind randomized controlled trial, adults with acute low back or neck pain treated with opioids had no benefit in pain relief as those treated with placebo. In a large study of more than 21,000 participants aged 60 to 84 years, taking 60,000 IU vitamin D each month slightly reduced their likelihood of experiencing a major cardiovascular event (number needed to treat = 172 over 5 years). A single screening colonoscopy had higher rates of participation than 5 years of fecal occult blood testing in a high-quality study in which patients were offered free screening with these two methods (84% vs 73%; p<0.001).

Actigraphic Correlates of Neuropsychiatric Symptoms in Adults with Focal Epilepsy.

Disability in patients with epilepsy (PWE) is multifactorial: beyond seizure frequency/severity, PWE are prone to a range of neuropsychiatric, cognitive, and somatic comorbidities that significantly impact quality of life. Here, we explored how variations in seizure severity and the burden of self-reported somatic/neuropsychiatric symptoms correlate with disruptions to 24h activity patterns (rest-activity rhythms, RARs), determined through wrist accelerometry/actigraphy. Multiday wrist-actigraphy recordings were obtained from 59 adult patients with focal epilepsy (44% male, ages 18-72), who contemporaneously responded to validated psychometric instruments to measure anxiety, depression, sleepiness, and somatic symptoms. We conducted a similar in silico psychometric-actigraphic correlation in a publicly available dataset of 1747 Hispanic subjects (35% male, ages 18-65) from the Study of Latinos (SOL) Sueño Ancillary Study. RARs were analyzed via a sigmoidally-transformed cosine model (quantifying amplitude, steepness, acrophase and robustness) and non-parametric measures to estimate RAR stability, fragmentation, and sleep. Compared with matched SOL subjects, RARs from PWE subjects featured a significantly lower amplitude, a wider rest phase and significantly more total daily sleep. Within PWE, similar RAR distortions were associated with seizure intractability and/or anticonvulsant polytherapy, whereas high anxiety, depression, and somatic symptom scores were associated with lower RAR robustness and acrophase delay. We applied the SOL dataset to train logistic regression models to dichotomously classify subjective anxiety, depression and sleepiness symptoms using demographic and RAR parameters. When tested on PWE, these models predicted prevalent anxiety and depression symptom burden (accuracy ~70%) but failed to predict subjective sleepiness. Together, these results demonstrate that RAR features may encode prevalent depression and anxiety symptoms in patients with focal epilepsy, potentially offering wearable-derived endpoints to adjunct clinical care and drug/device trials. With larger PWE-specific actigraphic-psychometric datasets, we may identify RAR signatures that may more precisely correlate with varying seizure frequency, the burden of anticonvulsant therapy and prevalent mood/anxiety symptoms.

Management of neuropsychiatric symptoms in adults treated with elexacaftor/tezacaftor/ivacaftor.

Reports of neuropsychiatric symptoms proximal to cystic fibrosis transmembrane conductance regulator (CFTR) modulator initiation are emerging, but their prevalence and management remain poorly characterized. Retrospective chart review was used to categorize symptom trajectories of all adults at a single CF Center who initiated elexacaftor/tezacaftor/ivacaftor (ETI) before March 2022 and subsequently had ≥1 outpatient visit with the consulting CF psychiatrist. For those who developed neuropsychiatric symptoms probably related to ETI and modified treatment in response, the strategy resulting in greatest improvement with acceptable physical course and tolerability was identified. Ratings were made by a psychiatrist not involved in clinical care. Of 148 adults initiating ETI, 31 were psychiatrically evaluated, 16 of whom developed new/worsening and unexpected neuropsychiatric symptoms probably related to ETI, including neurocognitive (word finding, brain fog, memory, attention/concentration), insomnia, depression, anxiety, fatigue/low energy, mania/hypomania, other distress. This group had higher maximum lifetime Generalized Anxiety Disorder-7 scores (14.42 ± 0.96; p = 0.05) than those with improved, unchanged, or worsening/possibly related symptoms (N = 15; 9.9 ± 1.82). Treatment strategies resulting in much/very much improvement included pharmacologic interventions, psychotherapy, and dose reduction/discontinuing ETI. Although many people initiating ETI experience improved physical and mental health and quality of life, a subset report worsening neurocognition, mood, and anxiety. As novel therapies are developed, ascertaining and evaluating neuropsychiatric symptoms in clinical and research settings is advisable. Larger studies are needed to characterize prevalence, course, and risk factors (e.g., age, gender, clinical status, pharmacokinetics/pharmacogenomics, drug-drug interactions) for neuropsychiatric adverse events related to CFTR modulators and guide effective management.

Phenylalanine Effects on Brain Function in Adult Phenylketonuria

To evaluate the relationship between circulating phenylalanine and brain function as well as neuropsychiatric symptoms in adults with phenylketonuria. In this prospective cross-sectional study, early-treated patients with phenylketonuria older than 30 years and age- and sex-matched controls were included. Extensive neurologic evaluation, neuropsychological and behavioral testing, sensory and motor evoked potentials, and MRI were performed. CSF concentrations of neurodegenerative markers were evaluated in addition in a subset of 10 patients. Nineteen patients with phenylketonuria (median age 41 years) with different phenylalanine levels (median 873 μmol/L) entered the study. They showed higher prevalence of neurologic symptoms, cognitive and behavioral abnormalities, autonomic dysfunction, alterations in neurophysiologic measures, and atrophy in putamen and right thalamus compared to controls. In CSF, patients with phenylketonuria exhibited higher β-amyloid 1-42 (p = 0.003), total tau (p < 0.001), and phosphorylated tau (p = 0.032) levels compared to controls. Plasma phenylalanine levels highly correlated with the number of failed neuropsychological tests (r = 0.64, p = 0.003), neuropsychiatric symptoms (r = 0.73, p < 001), motor evoked potential latency (r = 0.48, p = 0.030), and parietal lobe atrophy. Our study provides strong evidence for a correlation between phenylalanine levels and clinical, neuropsychological, neurophysiologic, biochemical, and imaging alterations in adult patients with phenylketonuria.

Music therapy for neuropsychiatric symptoms in the general hospital: a systematic literature review

Dementia and delirium are common in medical and surgical inpatients, and neuropsychiatric symptoms can be challenging to manage. Non-pharmacological interventions such as music therapy have been used to treat these symptoms in psychiatric hospitals and care homes but are not routinely used in general hospitals. We performed a systematic literature review to establish whether music therapy improves neuropsychiatric symptoms in adults with dementia and/or delirium in the general hospital setting. We searched CINAHL, Medline, PsycINFO in November 2015. Search terms included music therapy, dementia and delirium. Of 5054 titles reviewed we read 142 in full text of which none met inclusion criteria. We qualitatively reviewed six articles including 202 patients which could inform future research in music in general hospitals for people with dementia and/or delirium.  Music delivery was feasible and had a positive effect on some aspects of neuropsychiatric symptoms in various settings, but the studies were generally small, at high risk of bias, and did not use recognised frameworks for evaluating complex interventions. We found no published evidence for the use of music therapy in the treatment of neuropsychiatric symptoms in patients with dementia and/or delirium in the general hospital setting. Well-designed studies of this intervention are needed.

Differential associations between sensory loss and neuropsychiatric symptoms in adults with and without a neurocognitive disorder.

To investigate the differential associations between sensory loss and neuropsychiatric symptoms among older adults with and without diagnosed neurocognitive disorder. The sample comprised 1,393 adults (52.3% men) aged between 72 and 79 years from a community-based cohort study. There were 213 cases of mild and 64 cases of major neurocognitive disorders. The main outcome was number of informant reported symptoms on the Neuropsychiatric Inventory (NPI). Sensory loss was defined by visual acuity worse the 0.3 logMAR (6/12 or 20/40) and self-reported hearing problems. Clinically relevant NPI symptoms were reported in 182 (13.1%) participants, but no individual symptom occurred in more than 5% of the total sample. Among participants diagnosed with a major neurocognitive disorder, those with any sensory loss had over three times (95%CI: 1.72-11.78) greater rates of NPI symptoms than those with unimpaired levels of sensory functioning. There were no differences in the number of neuropsychiatric symptoms by type of sensory loss, and no additional risk associated with a dual sensory loss compared to a single sensory loss. There was no evidence of an association between sensory loss and number of neuropsychiatric symptoms among cognitively healthy adults. The extent to which this association is the result of underlying neuropathology, unmet need, or interpersonal factors is unclear. These findings have significant implications for dementia care settings, including hospitals and respite care, as patients with sensory loss are at increased risk of neuropsychiatric symptoms and may require additional psychosocial support. Interventions to manage sensory loss and reduce the impact of sensory limitations on neuropsychiatric symptoms are needed.

Aging and Autism Spectrum Disorder: A Naturalistic, Longitudinal Study of the Comorbidities and Behavioral and Neuropsychiatric Symptoms in Adults with ASD.

Little is known about Autism Spectrum Disorder (ASD) in persons over age 50. In a retrospective, naturalistic review of 74 individuals aged 30 and older meeting DSM-5 criteria for ASD, the point prevalence of behavioral and neuropsychiatric symptoms (BNPS) declined significantly for 12 of 13 BNPS over a mean of 25 years while many other features of ASD remained stable. GI disorders (68.9%) and seizure disorders (23%) were common, and 25.7% of the sample had a BMI >30. Females were more likely to engage in screaming (p < 0.05) and oppositional behavior (p < 0.05). Current age did not have a significant effect on BNPS prevalence.

Systematic Review and Meta-Analysis of Neuropsychiatric Symptoms and Executive Functioning in Adults With Phenylketonuria

ABSTRACTThis systematic review and meta-analysis (MA) investigates the impact of elevated blood phenylalanine (Phe) on neuropsychiatric symptoms in adults with phenylketonuria (PKU). The meta-analysis of PKU is challenging because high-quality evidence is lacking due to the limited number of affected individuals and few placebo-controlled, double-blind studies of adults with high and low blood Phe. Neuropsychiatric symptoms associated with PKU exceed general population estimates for inattention, hyperactivity, depression, and anxiety. High Phe is associated with an increased prevalence of neuropsychiatric symptoms and executive functioning deficits whereas low Phe is associated with improved neurological performance. Findings support lifelong maintenance of low blood Phe.

Multi-analyte profile analysis of plasma immune proteins: altered expression of peripheral immune factors is associated with neuropsychiatric symptom severity in adults with and without chronic hepatitis C virus infection.

BackgroundThe purpose of this study was to characterize hepatitis C virus (HCV)-associated differences in the expression of 47 inflammatory factors and to evaluate the potential role of peripheral immune activation in HCV-associated neuropsychiatric symptoms—depression, anxiety, fatigue, and pain. An additional objective was to evaluate the role of immune factor dysregulation in the expression of specific neuropsychiatric symptoms to identify biomarkers that may be relevant to the treatment of these neuropsychiatric symptoms in adults with or without HCV.MethodsBlood samples and neuropsychiatric symptom severity scales were collected from HCV-infected adults (HCV+, n = 39) and demographically similar noninfected controls (HCV−, n = 40). Multi-analyte profile analysis was used to evaluate plasma biomarkers.ResultsCompared with HCV− controls, HCV+ adults reported significantly (P < 0.050) greater depression, anxiety, fatigue, and pain, and they were more likely to present with an increased inflammatory profile as indicated by significantly higher plasma levels of 40% (19/47) of the factors assessed (21%, after correcting for multiple comparisons). Within the HCV+ group, but not within the HCV− group, an increased inflammatory profile (indicated by the number of immune factors > the LDC) significantly correlated with depression, anxiety, and pain. Within the total sample, neuropsychiatric symptom severity was significantly predicted by protein signatures consisting of 4–10 plasma immune factors; protein signatures significantly accounted for 19–40% of the variance in depression, anxiety, fatigue, and pain.ConclusionsOverall, the results demonstrate that altered expression of a network of plasma immune factors contributes to neuropsychiatric symptom severity. These findings offer new biomarkers to potentially facilitate pharmacotherapeutic development and to increase our understanding of the molecular pathways associated with neuropsychiatric symptoms in adults with or without HCV.
