Confusion and memory loss

Recent research has shed light on the connection between cardiovascular disease and memory loss. For people at risk of developing type 2 diabetes, it is important to be aware of the potential impact cardiovascular disease can have on brain health and memory.

Cardiovascular disease and memory loss

Cardiovascular disease refers to conditions that affect the heart and blood vessels, such as heart disease and stroke. These conditions often arise due to risk factors like high blood pressure, high cholesterol levels and high blood glucose. Other factors such as overweight or obesity and smoking can contribute too.

As well as the heart, cardiovascular disease can affect the brain. Memory loss, particularly problems with short-term memory, can occur as a result of the effect of reduced blood flow and oxygen supply caused by narrowed or blocked blood vessels over a period of time. Such damage can over time can result as memory problems, difficulty concentrating, and overall cognitive decline. This is sometimes known as vascular dementia. 

Why does it occur?

There are a number of things that contribute to the connection between cardiovascular disease and memory loss. One of the key factors is the reduced blood flow to the brain due to damaged blood vessels.

The brain relies heavily on a steady supply of oxygen and nutrients transported by blood to function as it should. When blood flow is reduced, there is a loss in brain function leading to problems like limb weakness and speech problems.

Additionally, cardiovascular disease increases the risk of stroke. A stroke occurs when blood flow to a part of the brain is interrupted or reduced, causing brain damage. Depending on the severity and location of the stroke, memory loss and other cognitive impairments can result.

Management and prevention

Understanding the relationship between cardiovascular disease and brain health can be helpful for individuals at risk of type 2 diabetes to prioritise their cardiovascular health. Here are some strategies that can help manage and prevent both conditions:

1. Adopt a heart-healthy lifestyle: Engage in regular physical activity, maintain a balanced diet rich in fruits, vegetables, whole grains, and lean proteins, limit saturated and trans fats, and avoid smoking.

2. Control blood pressure and cholesterol levels: Regularly monitor blood pressure and cholesterol levels and take necessary steps, including medication, if advised by healthcare professionals.

3. Maintain a healthy weight: Achieve and maintain a healthy weight through a combination of regular exercise and a nutritious diet.

4. Manage diabetes risk factors: Individuals at risk of type 2 diabetes should work towards preventing or controlling diabetes through lifestyle modifications, such as healthy eating, regular physical activity, and weight management.

5. Stay mentally active: Engage in activities that challenge the brain, such as puzzles, reading, learning new skills, and social interactions.

If you are worried about your memory or brain health, speak with your healthcare professional.
