The Tests for Parkinson's Disease

Parkinson's disease is a neurological movement disorder. Trying to diagnosis Parkinson's can be problematic, as other medical conditions such as palsy or Parkinsonism plus syndromes can mimic the disease. Parkinsonisms are movement disorders that are akin to Parkinson's type symptoms. Yet Parkinsonism also has symptoms that are distinct from Parkinson's. While tests for Parkinson's isn't exactly perfect, especially in the early stages of the disease, many tests may be performed to rule out other potential causes of your condition.

Neurological Exam

• A neurological exam requires you to perform multiple tasks, such as sitting, standing, walking, and reaching out your arms. Your balance and coordination while performing these tasks will also be observed. If it is shown that you have symptoms associated with Parkinson's, your physician may make a diagnosis. According to the Mayo Clinic, two of three Parkinson's symptoms (tremor, slow movements, and muscle stiffness) observed can make a confirmation of the disease. If a tremor is more pronounced while your hands are resting in your lap, Parkinson's may also be more likely.

Levodopa Test

• Levopoda is a medication that is commonly prescribed in the treatment of Parkinson's. According to the Mayo Clinic, the use of levopoda can help improve your muscle control. If your physician suspects you are suffering from Parkinson's, you may be prescribed levopoda for trial testing. If your symptoms improve, Parkinson's may be the likely culprit. If your symptoms don't improve, other neurological tests will be conducted to discern the cause of your condition.

SPECT

• SPECT, or single-proton emission computerized tomography, is a type of neuroimaging machine that can be used in the detection of brain disorders and other medical conditions. A SPECT can provide a 3-D image of your internal organs, such as your brain. When you undergo a SPECT, abnormalities or any inactivity within the areas of your brain can easily be detected.

Autonomic System Testing

• An autonomic system test measures the responses made by your cardiovascular, respiratory, and digestive systems. The test will also measure your reflexes, how you perspire, how you salivate, how your pupils dilate, and how much urine you excrete. Such functions are severely weakened if you suffer from Parkinson's.

Genetic Testing

• Heredity is a factor in the development of Parkinson's. The National Human Genome Research Institute suggests that if three or more people within your family have suffered from Parkinson's, a gene may be responsible for the cause of the disease. In cases of inherited Parkinson's, a gene known as PINK1 has been identified as the cause. This gene may be identified with genetic testing, especially in younger adults.
