Dr Alok Chopra highlights the effects of alcohol on the brain: he says it increases anxiety, depression, and mood swings, while reducing impulse control.

The relationship between alcohol and health is complex. While some studies suggest potential benefits from moderate drinking, Dr Alok Chopra, a cardiologist at Aashlok Hospital, Delhi thinks otherwise. According to him: ‘moderation isn’t protection — alcohol can still shrink your brain.’ He shared in a September 10 Instagram post: “Protecting your heart means protecting your brain. Alcohol quietly sabotages both.” Also read | Neuroscientist warns ‘avoid these 3 drinks because they are damaging your brain’

Dr Chopra went on to explain how even 'moderate' use of alcohol can ‘literally shrink your brain’. According to him, chronic alcohol use reduces brain volume, affecting decision-making and memory. Dr Chopra shared that alcohol alters sleep cycles, and impairs memory, attention, and executive function, potentially contributing to dementia.

Moreover, alcohol increases anxiety, depression, and mood swings while reducing impulse control, he added. Dr Chopra further explained that alcohol triggers inflammation, damaging neurons and increasing the risk of neurodegenerative conditions.

He shared the five effects of alcohol on the brain:

Brain shrinkage

“Chronic alcohol use reduces overall brain volume. Frontal Lobe (decision-making) and hippocampus (memory) are most affected. Resulting in memory issues, poor focus and slower thinking,” Dr Chopra said.

Neuro-inflammation

He added, “Alcohol triggers inflammation, damaging neurons and neural pathways. It is also known to increase the risks of neurodegenerative conditions over time.”

Sleep disruption

According to Dr Chopra, “Alcohol alters sleep cycles, reducing REM ( rapid eye movement) and deep sleep. Poor sleep affects memory, mood, and the brain repair processes.”

Cognitive decline

He said, “Alcohol impairs working memory, attention span, and executive function. Long-term use may contribute to alcohol-related dementia.”

Emotional and behavioural changes

Dr Chopra said, “It increases anxiety, depression, and mood swings and reduces impulse control and heightens risk-taking behaviour.”
