In brief
A condition that mainly affects movement and mood and gets worse over time. It happens when some nerve cells have low levels of dopamine, a brain chemical vital for controlling muscles and movement.
- CoQ10 did not improve symptoms in people with early Parkinson's disease, according to NCCIH.
- Parkinson's disease gets worse over time, according to healthdirect.
How it works
Common signs include a tremor at rest, usually on one side at first, slowing of movement, and sleep problems, including acting out dreams. Most people are diagnosed at around 65.
Medicines for Parkinson's disease increase dopamine levels in the brain. Levodopa is a building block used to replace dopamine, and dopamine agonists copy the effects of dopamine.
