What Are the Five Stages of Parkinson's Disease?

Parkinson's Disease is a neurological disorder that occurs when the cells in the brain that produce dopamine are rendered nonfunctional. Dopamine allows for coordinated gross and fine motor movement, including fluent speech and good balance. Parkinson's Disease affects both genders equally. Eighty-five percent of those diagnosed are over the age of 50. Parkinson's Disease typically has five stages.

Stage One

• Symptoms are mild in this stage and are typically first noted by a family member of friend of the patient. The patient experiences slight tremors in one side of the body and may reflexively roll her thumb and forefinger together in a "pill rolling" motion. Poor posture and loss of balance may be noted.

Stage Two

• In this stage, symptoms are bilateral (affecting both sides of the body). Lack of balance and difficulty walking are noticeable.

Stage Three

• In the third stage of Parkinson's Disease, a patient is unable to stand or walk in a straight path. Extremely slow physical movement (bradykinesia) is noted.

Stage Four

• Severe symptoms manifest in the fourth stage of Parkinson's Disease. Walking may still occur, but will be infrequent. Alzheimer's symptoms may develop. The patient is unable to complete the activities of daily living without assistance.

Stage Five

• In the last stage of Parkinson's Disease, the patient is typically immobile and will require around-the-clock nursing care.
