Alzheimer's disease is a neurodegenerative disorder characterized by the progressive loss of nerve cells, triggered by the abnormal accumulation of beta-amyloid and tau proteins in brain cells. This condition results in memory loss, dementia, and a significant decline in the ability to perform daily living activities. The disease primarily affects areas of the brain associated with learning, thinking, and remembering, leading to severe cognitive impairments.
In advanced stages of the disease, significant brain tissue shrinkage and widespread cell death are observed. This process causes individuals to completely lose their independence and experience severe difficulties in maintaining basic physiological functions.
Early symptoms of Alzheimer's typically manifest as forgetfulness, which may include difficulty recalling recent events, newly learned information, or conversations, forgetting the names of places and objects, or misplacing items in unusual locations. As the disease progresses, more pronounced cognitive and behavioral symptoms emerge, such as poor decision-making, personality changes (e.g., aggression), and the loss of ability to perform basic daily tasks like bathing.
