Generic Artane is used to treat Parkinson's disease. By improving muscle control and reducing stiffness, this medicine allows more normal movements of the body as the disease symptoms are reduced.

Generic Aricept is used for treating dementia (eg, impairment of memory, judgment, and abstract thinking; changes in personality) in patients with Alzheimer disease.

Exelon (rivastigmine) improves the function of nerve cells in the brain. It works by preventing the breakdown of a chemical that is important for the processes of memory, thinking, and reasoning. People with dementia usually have lower levels of this chemical. Exelon is used to treat mild to moderate dementia caused by Alzheimer's or Parkinson's disease. Exelon is not a cure for Alzheimer's or Parkinson's disease.
