Alzheimer's disease is a type of dementia that causes memory, cognitive, and behavioural issues. Dementia is defined as the loss of psychological working thinking, memory, and thinking and social capacities to the point when it interferes with an individual's daily life and workouts. Memory, language skills, visual observation, critical thinking, self-management, and the ability to center and focus are examples of these abilities. Some people with dementia are unable to manage their emotions, and their personalities may change. Everyone's disease progresses at a different rate, but in general, people with Alzheimer's survive for a long period after symptoms appear. While there are no medications available to prevent Alzheimer's disease from progressing, there are medications available to address dementia adverse effects.
