In the United States, more than 450,000 patients are on dialysis due to end-stage renal disease. Compared to the general population, these patients account for a disproportionate number of emergency department visits due to higher rates of infection and cardiovascular complications, as well as issues unique to the process of dialysis itself, such as vascular access problems and dialysis disequilibrium syndrome. This issue describes the pathophysiology arising from hemodialysis and peritoneal dialysis-related complications, as well as the evaluation and initial treatment within the emergency department, based on best available evidence.

Beyond the hippocampus: Amygdala and memory functioning in older adults.

Behav Brain Res

August 2024

Pacific Neuroscience Institute Foundation, Pacific Brain Health Center, 1301 20th St, Suite 250, Santa Monica, CA, USA; Department of Psychiatry and Biobehavioral Sciences, David Geffen School of Medicine at the University of California, 855 Tiverton Dr, Los Angeles, CA, USA.

Background: Medial temporal lobe atrophy has been linked to decline in neuropsychological measures of explicit memory function. While the hippocampus has long been identified as a critical structure in learning and memory processes, less is known about contributions of the amygdala to these functions. We sought to investigate the relationship between amygdala volume and memory functioning in a clinical sample of older adults with and without cognitive impairment.
