The condition affects the way a patient speaks, thinks, feels and behaves.
Symptoms of dementia include memory loss, difficulty concentrating, mood changes, and difficulty finding the right words.
You could lower your risk of dementia by avoiding certain foods. The MIND diet (Mediterranean-DASH Intervention for Neurodegenerative Delay) could help to prevent the condition, studies have claimed.
“The MIND diet is designed to prevent dementia and loss of brain function as you age,” said medical website Healthline.
“It combines the Mediterranean diet and the DASH diet to create a dietary pattern that focuses specifically on brain health.
“Research has shown that following the MIND diet even a moderate amount is associated with a reduced risk of Alzheimer’s disease.
“The MIND diet encourages limiting your consumption of butter and margarine, cheese, red meat, fried food, pastries and sweets because they contain large amounts of saturated fat and trans fat.”
You should eat less than one tablespoon of butter or margarine a day, the diet suggests.
Limit your cheese consumption to less than once a week, and no more than three servings of red meat per week. That includes all beef, pork and lamb, as well as any products made from the meats.
Fried food should be avoided, with less than one serving per week.
Also, cut back on pastries and sweets, including most of the “processed junk food”. Eat these foods no more than four times a week.
There’s no certain way to prevent dementia, but some lifestyle changes can help to lower your risk of the condition.
Those most at risk of dementia are the elderly, and those with lower levels of education, the NHS said.
A diet high in saturated fat, salt and sugar can increase your risk of dementia.
Regular exercise may help to prevent a neurodegenerative condition, it added.
