Background: The onset of the COVID-19 pandemic precipitated a rapid shift to virtual care in health care settings, inclusive of mental health care. Understanding clients' perspectives on virtual mental health care quality will be critical to informing future policies and practices.
Objective: This study aimed to outline the process of redesigning and validating the Virtual Client Experience Survey (VCES), which can be used to evaluate client and family experiences of virtual care, specifically virtual mental health and addiction care.

Background: We recently reported genetic associations with dementia-related proteinopathies. Using multidimensional generalized partial credit modeling, we constructed three continuous latent variables, corresponding to TDP-43, Aβ/Tau, and a-synuclein related neuropathology endophenotype scores.
Method: Participant data were drawn from the National Alzheimer's Coordinating Center (NACC) neuropathology (NP) data (from the September 2023 data freeze) linked to Alzheimer's Disease Genetics Consortium (ADGC) genotype data.

Background: In cognitively unimpaired (CU) older adults, the presence of a subjective cognitive decline (SCD) combined with evidence of abnormal b-amyloid (Ab) is proposed as stage 2 of Alzheimer's disease (AD) by the NIA-AA framework (Jack et al., 2018). However, the associations found between SCD and preclinical AD are inconsistent across studies, highlighting the importance of better understanding which specific SCD features are associated with either Ab or tau burden.

Background: The relationship between Alzheimer's disease (AD) pathology and the associated clinical syndrome a patient presents with remains indeterminate. Cognitively-defined subgroups of AD have revealed distinctions based on relative cognitive impairments, including AD-Language, where challenges in language are substantial, and AD-No Domain, where no relative asymmetries across cognitive domains occur. Pathological features of AD have been associated as the primary neuropathology of the logopenic variant of primary progressive aphasia (lvPPA).

University of Southern California, Los Angeles, CA, USA.
Background: Cerebrovascular reactivity (CVR) is a marker of cerebrovascular function defined by blood flow changes in response to vasoactive stimuli, which may represent a valuable indicator of risk for vascular brain injury and cognitive decline. Understanding of sex specific CVR patterns is limited, yet likely important for understanding vascular risk. Previous research on sex differences in CVR is mixed, and has predominantly focused on younger adults and utilized Transcranial Doppler ultrasound approaches that focus on large intracranial artery flow.
