Brain health: Alcohol consumption and lifestyle habits impact cognitive decline

Neurologists and researchers have identified key lifestyle factors that influence the rate of brain aging and cognitive decline. Experts warn that regular alcohol consumption acts as a neurotoxin, potentially reducing the volume of both gray and white matter in the brain. This impact can impair memory, emotional regulation, and efficient communication between brain regions. Furthermore, alcohol can disrupt sleep quality and damage blood vessels, increasing risks for hypertension and stroke.

Conversely, a study published in ‘Alzheimer’s & Dementia’ suggests that maintaining physical activity and managing blood glucose levels are essential for slowing cognitive decline. Researchers noted that the brain relies on a steady supply of glucose and oxygen; while low glucose can harm nerve cells, excessively high levels can damage blood vessels and reduce cerebral blood flow. Regular exercise is highlighted as a vital tool to provide oxygen to the brain and protect vascular health.
