Parkinson's disease symptoms mainly relate to movement because the condition results in a loss of nerve cells in the part of the brain responsible for producing a chemical called dopamine. Dopamine acts as a messenger between the parts of the brain and nervous system that help control and coordinate body movements. One area of the body that can be affected is the feet. If stiffness in the feet occurs often, it could be a sign of something more serious.
Parkinson’s disease is a condition that causes the brain to become progressively more damaged over time, said the NHS. You could be at risk of the neurodegenerative condition if you find that you're not blinking as often as you're used to.
Living near major roads or highways is linked to higher incidence of dementia, Parkinson's disease, Alzheimer's disease and multiple sclerosis (MS), suggests new research published this week in the journal Environmental Health.
Scientists have discovered that a non-invasive technique which could one day be used to treat Parkinson's disease, can successfully target a highly specific group of brain cells which play a key role in development of the condition.
The brain chemical missing in Parkinson’s disease may have a hand in its own death. Dopamine, the neurotransmitter that helps keep body movements fluid, can kick off a toxic chain reaction that ultimately kills the nerve cells that make it, a new study suggested.
