Heart failure compromises cognitive skills

In a study of 155 adults, geriatric psychiatrist Professor Osvaldo Almeida and colleagues found patients with heart failure had worse psychomotor speed and poorer immediate and long-term memory than people free from heart failure or ischaemic heart disease. 

MRI scans showed they also experienced a disproportionate loss of cerebral grey matter in brain regions relevant to cognitive function.

“These deficits were subtle, but they did affect patients’ abilities to complete tasks that required mental effort, focus, concentration or required people to multitask.”
