Dementia is a general term for a decline in mental ability severe enough to interfere with daily life. Memory loss is an example. Alzheimer's is the most common type of dementia.
Dementia is not a specific disease. It's an overall term that describes a wide range of symptoms associated with a decline in memory or other thinking skills severe enough to reduce a person's ability to perform everyday activities.
While symptoms of dementia can vary greatly, at least two of the following core mental functions must be significantly impaired to be considered dementia:
- Communication and language
- Ability to focus and pay attention
- Reasoning and judgment
- Visual perception
The six pillars of a brain-healthy lifestyle are:
- Regular exercise
- Healthy diet
- Mental stimulation
- Quality sleep
- Stress management
- An active social life
