Diagnosing Parkinson's disease

There is no test to diagnose Parkinson's disease so it can be difficult to make an accurate diagnosis. The symptoms of Parkinson's disease and the rate the disease progresses can vary.

To diagnose Parkinson's disease a doctor will take a complete medical history and conduct a neurological examination. A doctor will be looking for 2 to 4 symptoms of Parkinson's disease that present over a period of time.

Symptoms of Parkinson's disease a doctor will be looking for include:

• Tremor or shaking
• Rigidity and stiffness
• Problems with balance
• Slowness of movement

Many other disorders can have similar symptoms to Parkinson's disease making it difficult to diagnose. People can have Parkinson-like symptoms referred to as parkinsonism. Certain medications, neurological conditions and vascular problems can present with symptoms that mimic Parkinson's disease.

Other symptoms of Parkinson's disease can be less noticeable including fatigue, muscle pain, soft voice or mild depression.

Diagnosing Parkinson's disease will include brain scans and a variety of blood tests to help rule out other conditions. A doctor may refer a person to a neurologist to confirm a diagnosis of Parkinson’s disease.

Some people mistakenly dismiss the early symptoms of Parkinson's disease as signs of old age. Family members often notice signs of early Parkinson's.

In the early stages a person may appear stiff or unsteady on their feet. You may notice a loved one's expression appears less animated or blank. Over time these symptoms can become more pronounced prompting people to see their doctor.

In the early stages a doctor may want to observe a person over a period of time before diagnosing Parkinson's disease.
