Alzheimer’s disease is a progressive neurological disorder that affects memory, thinking, and behavior. It is the most common form of dementia and primarily affects older adults, though early-onset cases can occur. The disease develops when brain cells degenerate, causing a steady decline in cognitive abilities.

Early signs often include forgetfulness, difficulty finding words, and trouble with problem-solving or planning. As the disease advances, individuals may experience confusion, personality changes, and a loss of independence.

While there is no cure for Alzheimer’s, treatments such as medications and lifestyle interventions can slow progression and improve quality of life. Mental stimulation, physical activity, and a supportive environment are essential for both patients and caregivers navigating this challenging condition.
