Alzheimer's disease is a progressive brain disorder that is the most common cause of dementia, characterized by the gradual and relentless decline of memory, thinking, and behavior. The disease is believed to be caused by a combination of age, genetic, and lifestyle factors. The hallmark pathological features are the accumulation of amyloid plaques and tau tangles, which disrupt communication between brain cells and ultimately lead to cell death. The disease begins with minor memory loss, forgetfulness of recent events, difficulty finding words, and problems with planning or reasoning and as it progresses can lead to confusion, disorientation, mood swings, and behavioral changes, and the inability to perform simple daily tasks. In later stages, individuals may require assistance with daily living activities and experience a loss of motor functions. Currently, there is no cure for Alzheimer's disease, but medications can help manage symptoms and treatments can slow its progression for some people.
