12 Early Warning Signs Of Parkinson’s Disease

6. Dizziness and Fainting

If you’ve experienced the feeling of dizziness more than a few times over the period of some time, you could have symptomatic Neurogenic Orthostatic Hypotension (NOH). According to the NHS, this is a condition that occurs when a person’s blood pressure drops suddenly while standing up, and is a common symptom among Parkinson’s patients. In fact, this is a symptom that is present in about 15-50% of people with the illness.

Doctors believe this symptom occurs due to the lack of norepinephrine in the nervous system, which is a “a chemical that ‘talks’ to sensors on your blood vessels telling them to tighten, or constrict, which raises your blood pressure and brings blood back up to your brain,” as defined by the NHS. Furthermore, an improper blood flow to the brain could also cause dizziness, lightheartedness, and even fainting.
