Here, we describe severe neuropsychiatric symptoms in an HIV-positive Asian man with extremely high efavirenz plasma levels while receiving standard treatment with efavirenz/tenofovir/emtricitabine fixed-dose regimen. Genetic examination revealed compound homozygosity for loss-of-function alleles of CYP2B6, including coding for a rare truncated protein. Neuropsychiatric symptoms resolved completely after efavirenz discontinuation.

Background: Patients with Alzheimer's Disease (AD) frequently manifest comorbid neuropsychiatric symptoms (NPS) with depression and anxiety being most prevalent. Previously we identified shared genetic risk loci between AD and major depressive disorder (MDD). In another study, we constructed a polygenic risk score (PRS) based on MDD-GWAS data and demonstrated its performance in predicting depression onset in LOAD patients.

Alzheimers Dement
December 2024
Columbia University, New York, NY, USA.
Background: As high as 50% of Alzheimer's disease (AD) patients experience "sundowning", which refers to an increased severity of neuropsychiatric symptoms (NPS), including agitation, confusion, and anxiety, selectively in the evening. Although sundowning significantly influences the decision to institutionalize patients, few preclinical models of this phenomenon exist and the underlying neural mechanisms are unknown. Here, we establish a model of sundowning by phenotyping the sleep-wake cycle and anxiety and exploratory behavior at different times of day in an AD mouse model.

Background: Nearly all individuals with Alzheimer's disease (AD) develop neuropsychiatric symptoms (NPS). Lithium is a mood-stabilizer and is efficient in reducing disruptive behaviors in bipolar-disorder; this characteristic could be an opportunity to investigate the use of lithium in treating behavioral changes in AD.
Method: We tested lithium carbonate treatment in 3xTg-AD and age-matched Wild-type male mice (CEUA/PROCESS: 1605/2020; 4127240122).

Alzheimers Dement
December 2024
The Clinical Hospital of Chengdu Brain Science Institute, MOE Key Lab for Neuroinformation, School of Life Science and Technology, University of Electronic Science and Technology of China, Chengdu, China.
Background: To study the morphological characteristics of the thalamus in cognitively normal people with apolipoprotein E epsilon 4 (APOE ε4), and to explore whether it is affected by neuropsychiatric symptoms in patients aged between 60 and 70 years, and to provide evidence for the early brain structural changes in Alzheimer's disease.
Method: Clinical assessment, neuropsychological assessment, blood text and MRI examination were performed in 101 cognitively normal elderly patients in a tertiary psychiatric memory clinic in Chengdu. The cognitive function and thalamic volume of APOE ε4 carriers (n = 30) and APOE ε4 non-carriers (n = 71) were compared using an independent sample T-test.

Background: Neuropsychiatric Symptoms (NPS) (e.g., aggression, psychosis, anxiety, apathy, depression, agitation, sleep disturbances, repetitive behaviors) occur in 85% of AD patients, and are associated with accelerated decline, out-of-home placement, increased costs, and greatly increased suffering of patients and families.
