Alzheimer's disease is characterized by a loss in these functions, and is eventually fatal, stemming from brain failure. It is genetic and may be influenced by environmental factors like smoking, diet, traumatic brain injury and diabetes among others.

Parkinson's disease is characterized by rigid muscles, tremors, and slowed motion. This may be cased by several non specific conditions such as poisoning, brain damage, head trauma and other complex neurodegenerative diseases.
