Understanding Dementia
Dementia is a complex neurological condition affecting cognitive function. It encompasses various disorders that impair memory, thinking, and behavior.
The Science Behind Dementia
Dementia results from damage to brain cells, disrupting their ability to communicate. This interference leads to cognitive decline and impacts daily functioning. In Alzheimer's disease, the most common form of dementia, abnormal protein deposits form plaques and tangles in the brain. These structures disrupt neuron activity and cause cell death.
Brain imaging techniques reveal shrinkage in affected areas. Neuron loss particularly affects regions responsible for memory, language, and reasoning. As the condition progresses, brain activity decreases in multiple areas.
Different Types of Dementia
Alzheimer's disease accounts for 60-80% of dementia cases. It typically begins with memory loss and progresses to impair other cognitive functions.
Vascular dementia, the second most common type, results from reduced blood flow to the brain. It often occurs after a stroke or series of small strokes.
Lewy body dementia involves abnormal protein deposits in the brain. It causes visual hallucinations and movement problems similar to Parkinson's disease.
Frontotemporal dementia primarily affects personality, behavior, and language. It tends to occur at a younger age than other forms.
