HIV-associated neurocognitive disorders (HAND) occur in approximately 50% of HIV-infected individuals, yet available diagnostic criteria yield varying prevalence rates. This study examined the frequency, reliability, and sensitivity to everyday functioning problems of three HAND diagnostic criteria (DSM-5, Frascati, Gisslén). Participants included 361(More)
The rapid peripartum onset of maternal caregiving involves progesterone synergizing with estradiol, but prolonging progesterone exposure past this time can prevent the emergence of mothering. Interestingly, there is a 7-10day-long rise in progesterone during mid-lactation, but its effects on mothering are unknown. Given progesterone's potential to inhibit(More)
OBJECTIVE Older adults commonly experience mild declines in everyday functioning and the strategic aspects of prospective memory (PM). This study used multiprocess theory to examine whether the strategic demands of retrieval cue type (event vs. time based) and delay interval length (2 vs. 15 min) influence the relationship between PM and activities of daily(More)
OBJECTIVE Prospective memory (PM) is described as the capacity to form and maintain an intention that is executed in response to a specific cue. Neural injury and associated neurocognitive disorders are common among persons living with HIV disease, who might therefore be susceptible to impairment in PM. METHOD This literature review utilized a structured(More)
Objective HIV-associated neurocognitive disorders (HAND) have historically been characterized as a subcortical condition that does not affect semantic memory; however, recent evidence suggests that the cortical regions that support semantic memory may be affected in HIV. Method The current study examined the effects of HAND on semantic memory in 85 HIV+(More)
BACKGROUND Frontal-striatal dysfunction has been linked to cognitive impairment in Huntington's disease (HD). The frontal lobes play a role in memory for the temporal order in which items occur in a sequence. However, little is known about temporal order memory in HD or how it may be affected by interference. OBJECTIVE The study assessed temporal order(More)
