Parkinson-plus syndromes are a group of neurological conditions that are similar to Parkinson's disease but have unique characteristics. These syndromes can be hard to diagnose because the symptoms mimic other conditions. Following are the four most common types of Parkinson-plus syndromes.
Parkinson's Disease. Parkinson's disease is a progressive and chronic nervous system disorder that affects movement and is caused by destroyed nerve cells in the brain. Although the progression of the disorder will vary from patient to patient, the development is often gradual, with symptoms sometimes going unnoticed for years. There is no cure for Parkinson's disease, but symptoms can be treated, and in some cases improved, with certain medications and other forms of treatment. It is estimated that approximately 50% to 80% of those with Parkinson's disease will eventually develop at least mild dementia, while up to 20% will develop full-blown dementia.
