Increased apathy post-interstitial laser capsulotomy for refractory obsessive-compulsive disorder.

BACKGROUND: MRI guided laser interstitial thermal therapy (M-LITT) capsulotomy has proven to be efficacious in decreasing refractory obsessive-compulsive disorder (OCD) related symptomatology yet capsulotomy either via radiosurgery or radiofrequency ablation has in some patients led to increased apathy following surgery. The current case series aims to investigate objective patient-reported change in apathy, disinhibition, depression, and executive dysfunction following anterior capsulotomy via M-LITT for OCD. METHODS: Ten consecutive patients pre- and post-M-LITT completed measures of OCD, apathy, disinhibition, executive dysfunction, and depression (Mtime between = 1.3 years; 0.42-3.7 years). Reliable Change Index (RCI) was used to evaluate change in pre- and post-M-LITT. OCD symptom response was evaluated using percent change (Y-BOCS scores: 24-34 % reduction indicating partial response; ≥35% reduction indicating full response). RESULTS: Positive post-surgical change was noted in OCD symptomatology with >65% reporting a partial or full response. However, six patients endorsed increased apathy with half of the non-responders (e.g., less than <24% score reduction on Y-BOCS) reporting increases in apathy. Patients reported relatively stable disinhibition and executive dysfunction, while over half reported a decrease in depression symptoms. Two of the non-responders and one responder endorsed increased apathy despite stable or improved depression symptoms, disinhibition, and executive dysfunction. CONCLUSIONS: Most patients in the current cohort achieved full-or-partial OCD recovery. Yet, 60% of patients also reported significant increases in apathy, despite experiencing a decrease in depression symptoms, with stable disinhibition and executive dysfunction. Despite these promising improvements in OCD symptomatology following M-LITT, further investigations of the impact of surgery and lesion location on apathy levels is clearly warranted using objective, quantifiable methods.

Case report: neuropsychological assessment in a patient with 4H leukodystrophy.

Objective: POLR3-HLD or 4H leukodystrophy is an autosomal recessive disorder characterized by hypomyelination, hypodontia, and hypogonadotropic hypogonadism, and caused by variants in POLR3A, POLR3B, POLR1C, or POLR3K genes. Neurological and non-neurological clinical features and disease severity vary. While previous studies reference variable cognition, this is the first report of 4H detailing a comprehensive neuropsychological assessment. Method: The current study presents a 20-year-old, English-speaking, right-handed, non-Hispanic White female with 12 years of education with genetically confirmed 4H POLR3B-related leukodystrophy without hormonal replacement treatment. Results: At age 4, developmental delays, ataxia, hearing loss, and abnormal dentition were present. Imaging, endocrinology, and neurologic examinations revealed hypomyelination, reduced cerebellar volume, delayed bone age density, osteopenia, and evidence of adrenarche without signs of true puberty. Neuropsychological assessment at age 20 revealed global cognitive impairment with intellectual, attention, verbal memory retrieval, construction, executive (e.g. processing speed, sustained attention) and math computation deficits, along with behavioral dysregulation. Conclusion: We present the first detailed neuropsychological assessment of a patient with 4H leukodystrophy. The neuropsychological assessment revealed cognitive and behavioral dysexecutive deficits aligning with hypomyelination observed on imaging. Further longitudinal studies are needed to shed light on the neurobehavioral presentation associated with this disorder to assist care providers, patients, and their families.

Life Interrupted: Family Routines Buffer Stress during the COVID-19 Pandemic.

Adoption of certain behavioral and social routines that organize and structure the home environment may help families navigate the challenges presented by the COVID-19 pandemic. The current cross-sectional study aimed to assess family routines prior to and during the COVID-19 pandemic and examine associations with individual and family well-being. Using a national sample, 300 caregivers of children ages 6-18 were surveyed using Amazon Mechanical Turk platform during the first three months of COVID-19 pandemic in the United States. Caregivers reported on family demographics, COVID-19-related stress, engagement in family routines (prior to and during the COVID-19 pandemic), stress mindset, self-efficacy, and family resiliency. Overall, families reported engaging in fewer routines during the COVID-19 pandemic compared to prior to the pandemic. COVID-19-related stress was highest in low-income families, families of healthcare workers, and among caregivers who had experienced the COVID-19 virus. Moreover, COVID-19-related stress was negatively related to self-efficacy, positively related to an enhancing stress mindset, and negatively related to family resilience. Engagement in family routines buffered relations between COVID-19-related stress and family resilience, such that COVID-19-related stress was not associated with lower family resilience among families that engaged in high levels of family routines. Results suggest that family routines were challenging to maintain in the context of the COVID-19 pandemic, but were associated with better individual and family well-being during this period of acute health, economic, and social stress.

The Lifespan Human Connectome Project in Aging: An overview.

The original Human Connectome Project yielded a rich data set on structural and functional connectivity in a large sample of healthy young adults using improved methods of data acquisition, analysis, and sharing. More recent efforts are extending this approach to include infants, children, older adults, and brain disorders. This paper introduces and describes the Human Connectome Project in Aging (HCP-A), which is currently recruiting 1200 + healthy adults aged 36 to 100+, with a subset of 600 + participants returning for longitudinal assessment. Four acquisition sites using matched Siemens Prisma 3T MRI scanners with centralized quality control and data analysis are enrolling participants. Data are acquired across multimodal imaging and behavioral domains with a focus on factors known to be altered in advanced aging. MRI acquisitions include structural (whole brain and high resolution hippocampal) plus multiband resting state functional (rfMRI), task fMRI (tfMRI), diffusion MRI (dMRI), and arterial spin labeling (ASL). Behavioral characterization includes cognitive (such as processing speed and episodic memory), psychiatric, metabolic, and socioeconomic measures as well as assessment of systemic health (with a focus on menopause via hormonal assays). This dataset will provide a unique resource for examining how brain organization and connectivity changes across typical aging, and how these differences relate to key characteristics of aging including alterations in hormonal status and declining memory and general cognition. A primary goal of the HCP-A is to make these data freely available to the scientific community, supported by the Connectome Coordination Facility (CCF) platform for data quality assurance, preprocessing and basic analysis, and shared via the NIMH Data Archive (NDA). Here we provide the rationale for our study design and sufficient details of the resource for scientists to plan future analyses of these data. A companion paper describes the related Human Connectome Project in Development (HCP-D, Somerville et al., 2018), and the image acquisition protocol common to both studies (Harms et al., 2018).
