Why is diagnosing Parkinson's disease difficult? How is the condition ultimately diagnosed and treated?

What will be an ideal response?

Diagnosing Parkinson's disease is difficult because there is no test that confirms the presence of the disease. It is diagnosed by exclusion, by a thorough examination to rule out other possible causes. Parkinson's symptoms can be treated. Some research has suggested that deep brain stimulation, stimulating specific parts of the brain with electricity, as well as resistance training can improve some of the motor symptoms. Most medications either replace or mimic dopamine, which temporarily improves the motor symptoms of the disease; anti-inflammatory medications may also help reduce neurodegeneration. Medication can temporarily reduce symptoms and perhaps slow its path, but Parkinson's disease is not curable.
