Parkinson’s disease can be defined as a progressive brain disorder that affects the nervous system, producing a continuous loss of muscle control. It happens when cells that normally produce dopamine, which is a chemical that carries signals between the nerves in the brain,” die.
Signs of Parkinson’s disease exhibit themselves slowly and worsen as the disease progresses over time. Although they differ from person to person, here are the most common early warning signs of Parkinson’s disease you should never ignore.
9Fainting and Dizziness
Feeling dizzy after standing up can occur from time to time, but if it is a persistent problem, it may be a symptom of Parkinson’s disease. Symptomatic neurogenic orthostatic hypotension (nOH)—when blood pressure falls suddenly after standing up—is quite common in those patients with Parkinson’s disease, affecting 15 to 50% of people.
Physicians think this happens because the nervous system may not be producing enough norepinephrine, “a chemical that ‘talks’ to sensors on blood vessels telling them to tighten, which raises blood pressure and brings blood back up to the brain.” Inadequate blood flow to the brain can lead to dizziness or fainting.
