The Link Between Hep C and Parkinson’s Disease
Parkinson’s disease is a progressive disorder of the nervous system that impairs movement. Many may be familiar with the well-known actor who has lived with Parkinson’s for decades in the public eye, Michael J. Fox. In Parkinson’s disease, certain nerve cells in the brain gradually break down or die. Many of the symptoms are due to a loss of nerve cells that produce a chemical messenger in the brain called dopamine. When dopamine levels decrease, it causes abnormal brain activity, leading to signs of Parkinson’s disease.
The three most common motor symptoms of Parkinson’s include:
- Bradykinesia – slowness of movement
- Rigidity – unusual stiffness in a limb or other body part
- Resting tremor – uncontrollable movement of a limb or body part when it is at rest
In addition to these motor-related symptoms, some additional signs of Parkinson’s include:
- Cognitive impairment
- Depression and anxiety
- REM sleep problems
- Speech and swallowing difficulties
The exact causes of Parkinson’s are unclear. Nonetheless, past studies imply that it may be triggered by a combination of environmental and genetic factors.
