Dementia is a broad term that describes a decline in cognitive function severe enough to interfere with daily life. It is not a specific disease but rather a group of symptoms that affect memory, thinking, behavior, and the ability to perform everyday activities. Dementia primarily affects older adults, although it is not considered a normal part of aging. Early diagnosis and intervention can improve the quality of life for those affected and provide crucial support to their caregivers.

Causes of Dementia

Dementia can result from various diseases and conditions. The most common causes include:

• The leading cause of dementia, characterized by the buildup of plaques and tangles in the brain that lead to cell death and tissue loss.
• Caused by reduced blood flow to the brain, often following a stroke or a series of small strokes.
• Involves abnormal deposits of a protein called alpha-synuclein in the brain, leading to cognitive decline and motor symptoms similar to Parkinson’s disease.
• Affects the frontal and temporal lobes of the brain, leading to changes in personality, behavior, and language abilities.
• A combination of two or more types of dementia, such as Alzheimer’s and vascular dementia.
• Conditions such as Huntington’s disease, Creutzfeldt-Jakob disease, and Parkinson’s disease can also lead to dementia.

Symptoms

The symptoms of dementia vary depending on the cause and the part of the brain affected. Common symptoms include:

• Memory Loss
