April is Parkinson’s Disease Awareness Month. Parkinson’s is a progressive nervous system disorder that greatly affects movement. It occurs when the brain cells that make the neurotransmitter dopamine stop working or die off. Symptoms often start with a small tremor, such as in the finger of one hand, and progress to affect the entire body.

Early Signs

The early signs of Parkinson’s include the following:
Resting tremor: A rhythmic, involuntary shaking that often starts in one area of the body, typically a finger, and will tremor at rest
Slowed movement: A slowing down of movement, known as bradykinesia, that occurs over time, making simple tasks, such as getting out of a chair and walking at normal speed, difficult
Rigid muscles: Stiffness and rigidity in muscles that is painful and limits range of motion
Impaired posture and balance: A stooped posture, rounded shoulders, or balance problems
Loss of automatic movements: Decreased ability to perform movements that occur unconsciously, such as blinking or smiling
Changes in speech: Slurred speech, as well as a softer volume, quicker cadence, and a hesitation before speaking
Changes in writing: A difficulty in handwriting that causes smaller than usual letters and crowded words to form
Loss of smell: Hyposmia, a condition that affects the ability to smell
Trouble sleeping: A thrashing about during sleep
Constipation: Painful or difficult bowel movements

Other signs include changes in vision, low blood pressure, sexual dysfunction, urine problems, and excessive perspiration.

Along with physical changes, a Parkinson’s sufferer may experience fluctuations in mood and thinking, such as the following:
• Apathy
• Memory and cognitive problems
• Mood disturbances
• Psychosis

Although Parkinson’s symptoms typically appear in older people, about 10 to 20 percent of those with Parkinson’s experience symptoms before they turn 50.
