Cardiovascular disease and cognitive function in maintenance hemodialysis patients.

Background: Cardiovascular disease (CVD) and cognitive impairment are common in dialysis patients. Given the proposed role of microvascular disease on cognitive function, particularly cognitive domains that incorporate executive functions, we hypothesized that prevalent systemic CVD would be associated with worse cognitive performance in hemodialysis patients.

Design: Cross-sectional cohort.

Visual biasing of auditory localization in azimuth and depth.

Correctly integrating sensory information across different modalities is a vital task, yet there are illusions which cause the incorrect localization of multisensory stimuli. A common example of these phenomena is the "ventriloquism effect". In this illusion, the localization of auditory signals is biased by the presence of visual stimuli.

Cognitive function and dialysis adequacy: no clear relationship.

Background/aims: Cognitive impairment is common in hemodialysis patients and may be impacted by multiple patient and treatment characteristics. The impact of dialysis dose on cognitive function remains uncertain, particularly in the current era of increased dialysis dose and flux.

Methods: We explored the cross-sectional relationship between dialysis adequacy and cognitive function in a cohort of maintenance hemodialysis patients.

Depression and cognitive function in maintenance hemodialysis patients.

Background: Both depression and cognitive impairment are common in hemodialysis patients, are associated with adverse clinical outcomes, and place an increased burden on health care resources.

Study Design: Cross-sectional cohort.

Setting & Participants: 241 maintenance hemodialysis patients in the Boston, MA, area.
