Doctors Express Concern Over Alcohol’s Role in Rising Stroke Cases Among Youth

The increasing incidence of stroke among young adults has been strongly associated with lifestyle factors, especially the rising rates of alcohol consumption. While strokes were once predominantly a health issue affecting older adults, recent trends reveal that younger individuals are now facing higher stroke risks due to lifestyle choices. Heavy drinking is emerging as a critical concern, affecting brain health and overall well-being in ways that can lead to severe, life-altering consequences such as stroke. This shift is prompting medical professionals to examine the impacts of alcohol and other lifestyle factors that were previously thought to affect mainly older adults.

Research shows that stroke incidence is climbing in younger populations, with studies pointing to excessive alcohol use as a key contributor.

While strokes were once considered a condition predominantly affecting older adults, they are now occurring more frequently among younger people, largely due to lifestyle choices such as heavy drinking.

Findings from the 2022 INTERSTROKE study indicate that both high and moderate alcohol intake are associated with significantly higher odds of experiencing a stroke.

A stroke occurs when a part of the brain is deprived of oxygen, often due to a blood clot or the rupture of a blood vessel. This interruption causes brain cells to die, leading to potential disabilities such as difficulties with speech, mobility, cognitive function, and fine motor skills.

According to a recent study published in The Lancet, stroke-related deaths are projected to rise from 6.6 million in 2020 to an estimated 9.7 million by 2050. Although stroke is highly preventable and treatable, it may become responsible for nearly 10 million deaths each year by mid-century.

How Does Alcohol Affect the Brain?

Alcohol and tobacco are among the leading factors contributing to stroke risk, along with other lifestyle-related issues such as obesity, type 2 diabetes, chronic stress, sleep deprivation, and unhealthy diets. Dr. Kapil Kumar Singhal, Director of Neurology at Fortis Hospital in Noida, warns that alcohol consumption has significant long-term effects on brain health.

“Alcohol has harmful effects on the brain, affecting memory, cognition, behaviour, and decision-making,” he explained.

Frequent drinking can lead to brain shrinkage, neuron loss, and damage to synapses, which are essential for maintaining healthy brain function.

Dr. Singhal further emphasized that excessive alcohol consumption is associated with a higher risk of seizures and is strongly linked to an increased likelihood of stroke. 

“Current drinkers showed an increased risk of hemorrhagic strokes, while binge drinkers had even higher chances of severe strokes with poor outcomes,” said Dr Singhal, pointing out the INTERSTROKE study.

The risks associated with alcohol do not stop at the brain. Regular consumption is also closely linked to conditions such as high blood pressure, atrial fibrillation, and liver disease, all of which increase stroke risk.

Dr. Singhal explained that heavy drinking—defined as more than 15 drinks per week for women and over 21 for men—can raise stroke risk by 50%, particularly in the Indian population.

Adding to this, neurologist Dr. Nishta Jain from Shalby Hospital in Ahmedabad described how alcohol impacts the brain at a neurological level.

“Alcohol disrupts the natural connection between neurons, reducing brain activity and impairing cognitive function. It raises blood pressure and increases blood triglycerides, which can lead to atherosclerosis and ischemic strokes by blocking blood supply to the brain,” she said.

Dr Jain also warned of the dangers of binge drinking during short periods, such as weekend parties.

“Heavy drinking over a couple of days can dehydrate the body, thicken the blood, and increase the risk of clot formation, leading to stroke,” she said.

In August 2023, the World Health Organization cautioned that any amount of alcohol consumption poses health risks. Alcohol use significantly raises the likelihood of cancers, among other health issues.

Health experts stress the importance of reducing alcohol intake and avoiding binge drinking, especially for young adults looking to reduce their stroke risk.

“There is no ‘safe’ amount of alcohol for the brain. The damage it causes is both immediate and long-term,” underscored Dr Singhal.
