Age is the biggest risk factor for developing dementia, so it's only natural to worry about losing keys and forgetting names in middle age. However, memory loss is always the first sign of brain decline.

Anxiety can precede a diagnosis of dementia by 10 years.

“Anxiety is becoming an increasingly recognized predictor of cognitive decline in the elderly and in people with mild cognitive impairment,” says the BMJ. Anxiety may be an independent risk factor for dementia, defined here as preceding a diagnosis of dementia by up to 10 years.”

A study of 29,819 participants found a positive association between clinically significant anxiety and dementia in future.

“Clinically significant anxiety in midlife was associated with an increased risk of developing dementia for at least 10 years. They added that the discovery may indicate that anxiety may be a risk factor for 'senile dementia' – BMJ.

What is anxiety?

Anxiety is a feeling of worry or fear that can be mild or severe. Everyone experiences anxiety at some point in their lives. For example, you may feel anxious and worried about taking an exam, a medical test, or a job interview.

However, some people find it difficult to control their anxiety. Their feelings of anxiety are more persistent and can often affect their daily lives.

It is important to note that anxiety can also accompany a diagnosis of dementia.
