Dementia patients face a deterioration of intellectual abilities (e.g., vocabulary, abstract thinking, judgment, memory loss, physical coordination), the loss of which interferes with daily activities.

Dementia can be caused by degenerative diseases (e.g., Alzheimer’s, Huntington’s and Parkinson’s diseases), vascular diseases or stroke, metabolic disorders (thyroid, liver kidney dysfunction and certain vitamin deficiencies), AIDS, drugs and alcohol, and psychiatric disorders.
