The average amount of times a patient with Parkinson's blinks per minute can slow down to one or two times per minute, according to the American Parkinson Disease Association.
Blinking around 15 times a minute is considered healthy for most people. Those with Parkinson's or autoimmune disease Graves' disease may blink less. READ MORE: ExpertsA change in how often you blink might be a sign of an underlying health issue, experts say.
Research has shown that the average amount of times a patient with Parkinson's blinks per minute can slow down to one or two times per minute, according to the American Parkinson Disease Association. Studies have found that the rate at which we naturally blink echoes dopamine's activity in the brain.A distinctive feature of Parkinson's is the loss of dopamine-producing nerve cells, which can cause symptoms such as slower blinking and tremoring hands.The unpleasant sensation of being watched when no one is around is a symptom of early Parkinson’s that often goes overlooked, doctors say.
Symptoms are wide-ranging but can include a slight tremor of the hands or fingers, heat sensitivity, weight loss, an enlarged thyroid gland, bulging eyes and thick, red skin on the shins or feet.The condition occurs in almost one in every 100 Americans.It is caused by a malfunction in the body's disease-fighting immune system but scientists are not sure this happens.
A study in 2011 found that those with Graves' disease blinked slightly less frequently than healthy participants, with an average of 13 blinks per minute.Blinking more frequently, on the other hand, can be a sign of fatigue when trying to do a demanding task such as driving while lethargic.
