Objective: To evaluate the effect of virtual group music therapy on apathy in people with Parkinson's disease (PD).

Introduction: Apathy affects 40% of people with PD, lacks effective therapies, and independently predicts poorer quality of life and greater caregiver burden. Music therapy is the clinical application of music to address a person's physical or emotional needs and is effective in treating apathy in dementia.

Methods: People with idiopathic PD and apathy (Movement Disorders Society-Unified Parkinson's Disease Rating Scale, apathy item ≥ 2) and their caregivers participated in twelve, weekly virtual group music therapy sessions, with session attendance signifying adherence. Participants completed pre- and post-intervention assessments of apathy (Apathy Scale (AS)), quality of life (Parkinson's Disease Questionnaire-short form), functional ability (Schwab & England Activities of Daily Living Scale), depression (Beck Depression Inventory (BDI-II)), and cognition (Montreal Cognitive Assessment-Blind). Among secondary outcomes, we assessed caregiver burden (Zarit Burden Interview-short form) and strain (Multidimensional Caregiver Strain Index).

Results: Sixteen PD participants (93.8% men, mean age 68.3 ± 8.4 years, median 6 years PD duration) and their caregivers (93.8% women, mean age 62.6 ± 11 years) completed the study. All PD participants and 88% of caregivers were >70% adherent to the intervention. Apathy (AS, effect size = 0.767, P = 0.002) and depression (BDI-II, effect size = 0.542, P = 0.03) improved, with no change in caregiver measures.

Conclusion: Group music therapy is an effective treatment for apathy in PD and may improve mood. The virtual format is a feasible alternative to in-person sessions with high adherence and satisfaction.

Background: Enlarged perivascular spaces (EPVS) of the brain may be involved in dementia, such as Alzheimer's disease and cerebral small vessel disease (CSVD). Hypertension has been reported to be a risk factor for dementia and CSVD, but the association between blood pressure (BP) and perivascular spaces is still unclear. The aim of this study was to determine the association between BP and EPVS volumes and to examine the interactions of relevant factors.

Methods: A total of 9296 community-dwelling subjects aged ≥65 years participated in a brain magnetic resonance imaging and health status screening examination. Perivascular volume was measured using a software package based on deep learning that was developed in-house. The associations between BP and EPVS volumes were examined by analysis of covariance and multiple regression analysis.

Results: Mean EPVS volumes increased significantly with rising systolic and diastolic BP levels (P for trend = .003, P for trend<.001, respectively). In addition, mean EPVS volumes increased significantly for every 1-mmHg-increment in systolic and diastolic BPs (both P values <.001). These significant associations were still observed in the sensitivity analysis after excluding subjects with dementia.

Conclusions: The present data suggest that higher systolic and diastolic BP levels are associated with greater EPVS volumes in cognitively normal older people.

Objective: To extend prior research by examining daily driving frequency as a predictor of cognitive decline and later diagnosis of Alzheimer's disease.

Methods: 1,426 older adults completed batteries of questionnaires and neuropsychological tests at baseline and yearly follow-ups (M = 6.8, SD = 4.9). Linear mixed effects models were estimated to examine whether daily driving frequency at baseline was predictive of cognitive decline while accounting for IADLs, mobility, depression, and demographics. Cox regression was used to examine driving frequency as a predictor of Alzheimer's disease diagnosis.

Results: Less daily driving frequency was associated with greater decline in all cognitive domains over time except for working memory. Although driving frequency was associated with these changes in cognition, it did not uniquely predict the development of Alzheimer's disease when accounting for other factors (eg, other IADLs).

Conclusions: Our findings extend prior research linking driving cessation to greater levels of cognitive decline. Future work might benefit from examining the utility of driving habits (especially changes in driving) as measures of everyday functioning in older adult evaluations.

Objectives: Older adults with psychiatric illnesses often have medical comorbidities that require symptom management and impact prognosis. Geriatric psychiatrists are uniquely positioned to meet the palliative care needs of such patients. This study aims to characterize palliative care needs of geriatric psychiatry patients and utilization of primary palliative care skills and subspecialty referral among geriatric psychiatrists.

Methods: National, cross-sectional survey study of geriatrics psychiatrists in the United States.

Results: Respondents (n = 397) reported high palliative care needs among their patients (46-73% of patients). Respondents reported using all domains of palliative care in their clinical practice with varied comfort. In multivariate modeling, only frequency of skill use predicted comfort with skills. Respondents identified that a third of patients would benefit from referral to specialty palliative care.

Conclusions: Geriatric psychiatrists identify high palliative care needs in their patients. They meet these needs by utilizing primary palliative care skills and when available referral to subspecialty palliative care.

Assessment of personality disorders (PDs) in older adults is a nuanced trade of its own. The aim of this practice guide is to illustrate gerontological assessment challenges using 3 case vignettes. We argue that it is important to pay extra attention to the influence of cognitive and medical (somatic) disorders on personality functioning in older adults during personality assessment. We also note that information provided by informants contributes added value to personality assessment. Personality assessment should be sufficiently age-specific to prevent overdiagnosis or underdiagnosis in older adults. Furthermore, given the reduced psychological or somatic capacity of some older adults, phased or sequential personality assessment is recommended. This should be focused on the assessment questions to be answered, for example starting with short general screening of personality functioning, followed by more in-depth exploration. Personality assessment should be kept as brief and simple as possible in terms of formulation of the items.

Background: Subjective cognitive complaints are generally poorly associated with objective memory functioning in older persons. Subjective cognitive decline (SCD) is a key feature in SCD and amnestic mild cognitive impairment (aMCI) which both can represent early Alzheimer's disease (AD). The aim of this study was to assess how memory clinic patients with SCD, MCI and mild AD dementia scored on 3 different complaint measures and if the format of assessment had an impact on the association with cognitive functioning, age, and depressive symptoms.

Methods: We included 17 SCD patients, 17 aMCI patients, 17 patients with mild AD, and 30 controls. Complaints were assessed with the Cognitive Change Index (CCI), the Subjective Memory Complaints (SMC) scale, and the Memory Complaint Questionnaire (MAC-Q).

Results: There were no significant differences between the total scores in the patient groups on the questionnaires. However, significant differences were found in the number of patients classified with impairment when using the CCI, the SMC, and the MAC-Q. Scores on all questionnaires were significantly associated with depressive symptoms, and significant associations with age, gender, and Addenbrookes Cognitive Examination score were found for the SMC. In patients with cognitive dysfunction, lower memory awareness significantly predicted fewer cognitive complaints.

Conclusions: SCD patients in a memory clinic setting report the same degree of cognitive impairment as patients with aMCI and mild dementia, and in a hospital-based cohort we extend previous findings from healthy controls, that definition of SCD may depend on the format of assessment.

Background: Being diagnosed with a neurodegenerative disease is a life-changing event and a critical time to help patients cope and move forward in a proactive way. Historically, the main focus of Parkinson's disease (PD) treatment has been on the motor features with limited attention given to non-motor and mental health sequelae, which have the most impact on quality of life. Although depression and anxiety have been described at the time of PD diagnosis, demoralization, intolerance of uncertainty, decreased self-efficacy, stigma and loneliness can also present and have negative effects on the trajectory of the disease. Hence, understanding the psychological impact of the diagnosis and how to provide better counselling at this critical time point may be the key to a better long-term trajectory and quality of life.

Focus: There has been a paradigm shift in the treatment of chronic illness moving beyond the medical model, which focuses on fighting illness with the physician being in charge of the treatment process and the patient being the passive recipient, toward a more holistic (i.e., physical, psychological, social, and spiritual health) biopsychosocial approach that emphasizes behavioral factors with the patient being an active collaborator in their treatment. Hence, we propose that fostering resilience, social support, and psychological flexibility offer promise toward attenuating negative reactions and improving overall well-being.

Conclusion: Through a proactive wellness approach incorporating lifestyle choices, people with PD (PwP) can not only achieve improved states of health, well-being, and quality of life, but actually thrive.

Background: Parkinson's Disease (PD) affects over 10 million people worldwide. Many PD patients experience comorbid anxiety disorders, which have been correlated with reduced quality of life and can manifest at any time during the course of PD, including prior to motor symptom onset. Purpose: Prior work has demonstrated that patients diagnosed with depression following a PD diagnosis are less likely to receive depression treatment, but no such study has been conducted for anxiety. Research Design: A cross-sectional analysis of secondary electronhic health record data was conducted. Study Sample: Data was obtained through Optum® de-identified Electronic Health Record dataset, using ICD-9 and ICD-10 diagnosis codes to determine PD status and comparing index date of anxiety and PD diagnoses to classify patients by relative time of diagnosis. Data Analysis: Multivariate logistic regression was performed to assess factors associated with receipt of mental health treatment. Results: Of PD patients with anxiety, 52% documented a diagnosis of anxiety prior to PD. Overall, 69% documented some treatment, with 79% of those diagnosed with anxiety prior to PD receiving some treatment compared to 59% of those diagnosed with anxiety on or after PD (P < 0.001). Conclusion: Patients with PD and subsequent anxiety diagnoses are less likely to receive treatment. Further study could explore reasons for variations in mental health care within the context of an existing PD diagnosis.

Introduction: Active metabolite of vitamin D has neuro-immunomodulatory and neuroprotective properties. However, there is still a debate about the potential association between low serum levels of hydroxy-vitamin D and increased risk for dementia.

Objectives: To determine an association between hypovitaminosis D and dementia for different 25-hydroxyvitamin-D (25(OH)D) serum level cutoffs.

Methods: Patients were identified utilizing the database of Clalit Health Services (CHS), the largest healthcare provider in Israel. For each subject, all available values of 25(OH)D during the study period, which lasted from 2002 to 2019, were obtained. Rates of dementia were compared across different cutoffs of 25(OH)D levels.

Results: Cohort included 4278 patients, of whom 2454 (57%) were women. The mean age at the beginning of follow-up was 53 (±17). During the 17-year study period, a total of 133 patients (3%) were diagnosed with dementia. In a fully adjusted multivariate analysis, the risk for dementia was almost 2-fold higher in patients with an average of vitamin D insufficiency (<75 nmol/l) measurements (OR = 1.8, 95% C.I. = 1.0-3.2) compared to reference values (≥75 nmol/l). Patients with vitamin D deficiency (<50 nmol/l) demonstrated higher rates of dementia (OR = 2.6, 95% C.I. = 1.4-4.8). In our cohort, patients were diagnosed with dementia at a younger age in the deficiency (77 vs. 81 P-value = 0.05) and the insufficiency groups (77 vs. 81 P-value = 0.05) compared to the reference values (≥75 nmol/l).

Conclusion: Insufficient levels of vitamin D are associated with dementia. Dementia is diagnosed at a younger age in patients with insufficient and deficient vitamin D levels.
