Alzheimer’s Disease
Dementia is an umbrella term that describes symptoms affecting memory, thinking, and daily functioning. Alzheimer’s disease is the most common form. It often begins with short term memory loss and progresses gradually. Over time, language, reasoning, and physical abilities decline.
Vascular Dementia
Vascular dementia results from reduced blood flow to the brain, often related to strokes or small vessel disease. Symptoms may appear suddenly or progress in stages. Individuals often experience slowed thinking, difficulty with organization, and mood changes.
Lewy Body Dementia
Lewy body dementia involves abnormal protein deposits in the brain. This type may include visual hallucinations, fluctuations in alertness, sleep disturbances, and movement symptoms. Cognitive abilities may vary noticeably from day to day.
Frontotemporal Dementia
Frontotemporal dementia primarily affects the frontal and temporal lobes of the brain. Personality changes, impulsive behavior, or language difficulties may appear before memory problems. It often develops at a younger age than other types.
Why Diagnosis Matters
Mixed dementia occurs when more than one type is present. Because symptoms overlap, diagnosis may take time and involve cognitive testing and imaging studies. Understanding the specific type helps families prepare for progression patterns and choose appropriate care strategies.
Knowledge provides clarity and reduces uncertainty, allowing families to approach care with greater confidence.
