What is Dementia?
Dementia is not a single disease. It is a group of symptoms that affect:
- Memory
- Thinking
- Language
- Judgment
- Problem-solving abilities
- Daily functioning
Dementia occurs when brain cells become damaged and can no longer communicate effectively.
Worldwide, more than 55 million people live with dementia, and millions of new cases are diagnosed every year.
It is one of the leading causes of disability and dependence among older adults.
Dementia vs Normal Aging
Many people think memory loss is a normal part of aging. This is not entirely true.
Normal Aging
- Occasionally forgetting names
- Misplacing keys
- Taking longer to learn something new
- Forgetting why you entered a room
Dementia
- Forgetting close family members
- Getting lost in familiar places
- Difficulty performing daily tasks
- Significant personality changes
- Repeating the same questions many times
Dementia interferes with everyday life.
Understanding How the Brain Works
The brain controls:
- Memory
- Movement
- Speech
- Emotions
- Decision-making
- Personality
In dementia:
- Brain cells become damaged.
- Communication between brain cells breaks down.
- Certain parts of the brain shrink.
- Cognitive functions gradually decline.
Different areas of damage produce different symptoms.

Affects the frontal and temporal lobes.
Symptoms

5. Mixed Dementia
A combination of two or more forms of dementia.
Most commonly:
