Men at higher risk of dementia linked to heart disease, study finds

Men at risk for heart disease may develop dementia up to a decade earlier than similarly at-risk women, according to a recent study published in the Journal of Neurology, Neurosurgery & Psychiatry. This groundbreaking research highlights the significant link between cardiovascular health and cognitive decline, particularly for men.

The connection between Heart Disease and Dementia

Heart disease is a leading cause of death globally and is the No. 2 killer in Canada, according to the World Health Organization. Common risk factors include:

• Obesity
• Diabetes
• High blood pressure
• High cholesterol
• Smoking
• Excessive alcohol consumption
• Lack of exercise and proper sleep

These conditions can lead to small vessel disease, which restricts oxygen delivery to the brain and may contribute to dementia.

Study highlights

The study analyzed data from over 34,000 adults aged 45 to 82, focusing on the impact of heart disease risk factors, including abdominal and visceral fat, on brain health. Key findings include:

• Grey matter loss: Cardiovascular risk factors were associated with reduced grey matter in regions of the brain responsible for memory, vision, and emotional processing—areas commonly affected early in dementia and Alzheimer’s disease.
• Gender differences: Men aged 55 to 74 showed greater vulnerability to cardiovascular risks, while women experienced similar risks a decade later, between ages 65 and 74.

Dr. Paul Edison, lead author of the study, explained, “The influence of heart problems and obesity on brain cell degeneration is sustained and more apparent over twenty years in men than women.”

Why men are more vulnerable

The study identified several factors contributing to the earlier onset of dementia in men:

1. Lifestyle habits: Men are more likely to consume high-fat diets, smoke, drink alcohol, and carry visceral fat, which is linked to higher risks of heart disease and dementia.
2. Hormonal differences: Testosterone can elevate LDL (“bad” cholesterol) levels and increase inflammation, while estrogen in women provides protective effects until menopause.
3. Healthcare habits: Men may be less likely to seek treatment for cardiovascular issues compared to women.

Prevention: Start early

Preventing dementia starts with managing cardiovascular risk factors early, particularly for men in their 50s and 60s. Steps to maintain heart and brain health include:

• Control blood pressure, cholesterol, and blood sugar
• Adopt a healthy diet rich in fruits, vegetables, and lean proteins
• Stay physically active
• Quit smoking and limit alcohol consumption
• Get regular checkups to monitor heart health

Additionally, engaging in activities that stimulate cognitive function, such as puzzles, reading, or learning new skills, may help reduce the risk of dementia.

Can you qualify for disability benefits with heart disease?

In Canada, individuals diagnosed with heart disease may qualify for short-term disability (STD) or long-term disability (LTD) benefits if their symptoms or treatment side effects make it difficult or impossible to work. Common challenges such as severe fatigue, pain, or complications from treatment can significantly impact job performance and lead to time away from work.

How disability benefits can help

• Short-Term Disability (STD): Provides temporary financial support for individuals who cannot work due to heart disease or its treatments.
• Long-Term Disability (LTD): Offers income replacement for those unable to return to work for an extended period due to their condition.

To qualify for STD or LTD benefits, medical documentation is essential to demonstrate how heart disease limits your ability to perform your job duties. Unfortunately, insurance providers often deny valid claims, adding unnecessary stress to an already difficult situation.
