Parkinson's disease is a progressive nervous system disorder that affects movement that affects thousands of Irish people.
The American Parkinson's Disease Association says Seborrheic Dermatitis is "commonly found in people" with Parkinson's disease. "In much the same way that dysfunction of the autonomic nervous system cause non-motor symptoms in Parkinson's such as blood pressure dysregulation and urinary abnormalities, autonomic dysfunction of the nerves that control the oil glands of the face can cause seborrheic dermatitis".
While dermatitis is a common skin condition, for many, it can be chronic and, as a result, cause deterioration in mental health due to lowered self-esteem.
