A recent study published in Neurology has uncovered alarming associations between heavy alcohol consumption and significant brain health risks, bringing this global health concern closer to home for Thai readers. The research highlights that consuming eight or more alcoholic drinks per week is linked to an increased risk of brain lesions known as hyaline arteriolosclerosis, which are associated with memory and cognitive impairments. This finding is particularly pertinent for a society where social drinking is common, raising awareness about the potential long-term impacts on brain health.

In a concerning revelation for public health, recent research has established a link between heavy alcohol consumption and increased risk of brain lesions along with heightened odds of developing Alzheimer’s disease. According to a study published online in Neurology, consuming eight or more alcoholic drinks per week is associated with brain lesions known as hyaline arteriolosclerosis—indicative of damaged blood vessels that restrict blood flow, potentially impairing memory and cognitive abilities.

In a groundbreaking study, researchers have uncovered that increased blood flow correlates with greater stiffness in the hippocampus, a crucial brain area for memory and learning. This finding, significant for its implications for early Alzheimer’s detection, emerges from research conducted at the University of Washington.

The hippocampus holds particular importance because it is often one of the first brain regions affected by Alzheimer’s disease, which severely impacts memory and cognitive function. Scientists utilized magnetic resonance elastography (MRE) to precisely measure tissue stiffness, discovering that enhanced blood flow makes the hippocampus stiffer, a trait not observed in other brain regions.
