Dementia is an overall term for diseases and conditions characterized by a decline in memory, language, problem-solving and other thinking skills that affect a person's ability to perform everyday activities. Alzheimer’s Disease is a degenerative brain disease that is caused by complex brain changes following cell damage. It leads to dementia symptoms that gradually worsen over time, the most common early symptom of Alzheimer’s is trouble remembering new information because the disease typically impacts the part of the brain associated with learning first.

As Alzheimer’s advances, symptoms get more severe and include speaking, swallowing,  disorientation, confusion and behavior changes.
