Dementia: The social habit which could help ward off the condition – 'ways to reduce risk'

The NHS says: “It’s normal for your memory to be affected by stress, tiredness, certain illnesses and medicines.

“But if you’re becoming increasingly forgetful, particularly if you’re over the age of 65, it’s a good idea to talk to a GP about the early signs of dementia.”

Alzheimer’s disease is a type of dementia and, together with vascular dementia, makes up the majority of cases.

Memory loss is not the only common symptom.
