Comprehensive Guide to Alzheimer's Disease

Alzheimer’s disease is a degenerative brain disorder characterized by the progressive loss of brain cells, leading to cognitive decline. It is the most prevalent form of dementia, impairing social skills, behavior, and thinking abilities, thus affecting independence. Early symptoms often include forgetfulness and memory issues as the disease advances. Common signs include memory loss, difficulty reasoning, challenges with routine tasks, and personality changes such as depression, agitation, and social withdrawal. Brain alterations involve sticky plaques and tangles that damage healthy neurons, with risk factors including age, genetics, head injuries, lifestyle, and sleep patterns. Recognizing these factors and symptoms can aid early diagnosis and management.

Alzheimer’s causes brain shrinkage and cellular damage through the formation of beta-amyloid plaques and neurofibrillary tangles. These abnormalities disrupt neuron communication and nutrient transport, leading to cell death and cognitive decline. Reduced neurotransmitter production further hampers brain functions. Major risk factors include aging (especially over 65), family history, head injuries, poor sleep, lifestyle choices like inactivity, diabetes, high cholesterol, hypertension, smoking, and existing mild cognitive impairment. The interplay of genetic, environmental, and lifestyle influences contributes to the development of this progressive condition.
