Diagnosing the condition early could help to slow down the condition’s progress.
Making some small lifestyle changes could lower your chances of developing Alzheimer’s in later life.
“The early signs of the disease may be forgetting recent events or conversations,” it said.
“As the disease progresses, a person with Alzheimer’s disease will develop severe memory impairment and lose the ability to carry out everyday tasks.
“Brain changes that occur in Alzheimer’s disease can affect moods and behaviors.
“Problems may include the following depression, apathy, social withdrawal, mood swings, distrust in others, irritability and aggressiveness, changes in sleeping habits, wandering, loss of inhibitions, [and] delusions, such as believing something has been stolen.”
There’s no certain way to prevent dementia from developing, but there are ways to lower your risk, said the NHS.
Eating a healthy, balanced diet should help to lower your chances of developing dementia.
It’s also important to do enough exercise. Everyone should aim to do at least 150 minutes of moderate-intensity activity every week.
There are around 850,000 people in the UK with dementia, and the condition affects one in every six people over 80 years old.
