As Alzheimer's progresses, it can impact all aspects of daily life, including the ability to perform routine tasks, communicate, and maintain relationships. Patients may require increasing levels of care and support as the disease advances.

The exact cause of Alzheimer's is not fully understood, but it is believed to involve a combination of genetic, lifestyle, and environmental factors. Abnormal build-up of proteins in the brain, including amyloid plaques and tau tangles, is also associated with the disease.

Early signs of Alzheimer's include memory loss, difficulty completing familiar tasks, confusion with time or place, trouble understanding visual images and spatial relationships, problems with speaking or writing, and misplacing things.
