Is Alzheimer’s disease linked to other conditions?

We know that having one medical condition can cause others to develop. Research has shown that some people with diabetes or heart disease may have an increased risk of developing Alzheimer's disease.

Diabetes and Alzheimer’s disease

It is recognised that people with diabetes are more likely to develop dementia, including Alzheimer's disease - indicating a possible diabetes-Alzheimer's connection. There are several ways that diabetes could lead to dementia, for example - obesity is a strong risk factor for diabetes, and it is possible that obesity is also a risk factor for Alzheimer's. Although the exact link is unclear at this stage, research is ongoing to try and identify which aspects of diabetes influence the risk of developing dementia.

If you have got diabetes, it does not mean you'll develop Alzheimer's, or vice versa, but if you do suffer from both conditions, you may wish to consider some diet and lifestyle changes. Any changes you make for one condition are probably beneficial for the other. See our diet page for further information.

Heart disease and Alzheimer’s disease

Several possible risk factors for Alzheimer's and vascular dementia (resulting from blockages in blood vessels in the brain) are also linked to heart disease and stroke - high blood pressure, high cholesterol, high homocysteine levels, diabetes, smoking, stress and high levels of anxiety, as well as depression and a poor education. Remember - 'what is good for your heart is good for your brain'!

Depression and Alzheimer’s disease

The signs and symptoms of Alzheimer's disease and depression can be very similar, which often makes it difficult to recognise depression in a person with Alzheimer's disease.

However, it is estimated that 40% of people with Alzheimer's disease also suffer from depression. Changes in emotional symptoms like an increased feeling of hopelessness or crying more often are possible signs of depression. In this case, you should speak to your doctor who can advise on the best course of action.

If you are not diagnosed with either condition but experience the symptoms, it is very important you see your doctor. This will enable you to get an accurate diagnosis and the help you need.
