Following that, at the baseline and every 18 months, they conducted cognitive evaluations using a variety of psychological tests. These tests examined the following six cognitive domains: executive function, language, attention, processing speed, episodic recall memory, and the AIBL Preclinical Alzheimer Cognitive Composite (PACC).
PACC is a composite score that combines results from tests of cognition, executive function, and memory. It has been demonstrated by research that it can accurately measure the early stages of cognitive deterioration.
Data analysis revealed a favorable correlation between frequent coffee consumption and executive function, attentiveness, and PACC score. Over the course of the study, increased coffee consumption was linked to a slower loss of cognitive function in these areas.
According to the observed results, increasing daily coffee consumption from one to two cups may be able to slow cognitive aging by as much as 8% after 18 months. Over the same time frame, there may also be a 5% drop in the buildup of beta-amyloid in the brain.
