is a progressive disorder of the brain and the most common cause of dementia. It gradually damages nerve cells and the connections between them, affecting memory, thinking, language, behavior, and eventually the ability to perform everyday activities independently. The disease is associated with abnormal accumulation of beta-amyloid and tau proteins in the brain, alongside progressive loss of neurons and brain tissue.
Early Alzheimer's disease may appear as repeatedly forgetting recently learned information, difficulty planning or solving problems, getting confused about time or place, struggling with familiar tasks, or experiencing changes in mood and behavior. These changes should not simply be dismissed as normal aging. Early assessment can help distinguish Alzheimer's from other potentially reversible causes of cognitive impairment and from other forms of dementia.
Although there is currently no cure, early diagnosis has important benefits. It allows patients and families to plan care, address cardiovascular and lifestyle risk factors, access available treatments and support services, and make informed decisions while the individual can still participate in them. Regular physical activity, management of blood pressure and diabetes, avoiding to***co, maintaining social and cognitive activity, and protecting sleep and hearing health can all contribute to healthier aging.
