Dementia is a serious and progressive condition that affects memory, thinking, behavior, and the ability to perform daily activities. It is not a normal part of aging, although it is more common in older adults. Early awareness, timely diagnosis, and proper management can significantly improve quality of life for individuals living with dementia and their caregivers.
What Is Dementia?
Dementia is an umbrella term used to describe a group of neurological disorders characterized by a decline in cognitive function severe enough to interfere with everyday life. It affects memory, reasoning, communication, judgment, and emotional control.
Types of Dementia
Several types of dementia exist, including:
1. Alzheimer’s Disease
The most common form of dementia, accounting for the majority of cases. It primarily affects memory and learning.
2. Vascular Dementia
Caused by reduced blood flow to the brain, often due to stroke or chronic blood vessel damage.
3. Lewy Body Dementia
Associated with abnormal protein deposits in the brain, leading to memory loss, hallucinations, and movement problems.
4. Frontotemporal Dementia
Affects personality, behavior, and language, often occurring at a younger age compared to other dementias.
Common Causes and Risk Factors
Dementia can develop due to various factors, such as:
- Aging
- Family history of dementia

Diagnosis of Dementia
