Alzheimer’s disease attacks brain cells and neurotransmitters (chemicals that carry messages between brain cells), affecting the way your brain functions, your memory and the way you behave. It is also the most common form of dementia.
Dementia is a syndrome (a group of symptoms) associated with an ongoing decline in mental abilities.
While the exact cause is unknown, the risk of developing Alzheimer’s disease may be increased by a range of factors, including:
- a family history of the condition
- previous severe head injuries
- lifestyle factors and conditions affecting heart and brain health.
If you are worried that you may have Alzheimer’s disease visit your doctor to get some advice. Your doctor may ask you about any new or worsening problems you may have noticed such as:
- speech problems such as difficulty finding the right words
- difficulty in understanding what people are saying
- personality and mood changes
- difficulty with performing everyday routine activities.
There is no single test that can be used to diagnose Alzheimer’s disease. If your doctor suspects you may have Alzheimer’s disease, they may refer you to a specialist to confirm the diagnosis.
Although Alzheimer’s disease is not a normal part of ageing, it is more common in older people and may affect about one in four people over the age of 85.
