UT Southwestern Medical Center neurologists
are trained to diagnose and treat rare neurological conditions such as
Parkinsonism. Patients are often referred to our team when there is uncertainty
about their diagnosis.
Our Services
There is no single test to make a
definitive diagnosis of Parkinsonism. A diagnosis is made by assessing a
patient’s symptoms, medical history, family history, previous disorders, and
exposure to toxins and medications that might cause Parkinsonism.
A comprehensive physical
examination also helps determine the underlying condition. Diagnostic testing might
include:
- Blood tests: Sometimes used
to check for uncommon genetic, metabolic, nutritional, or endocrine diseases
that can produce the appearance of Parkinsonism
- Magnetic
resonance imaging (MRI), or
brain scan: Looks for a structural disorder that might be causing the symptoms
- Sweat test: Evaluates
perspiration to help assess autonomic function failure and can help identify
multiple system atrophy (MSA)
- Tilt table test: Assesses
whether a person’s blood pressure and heart rate can adjust normally to a
change in physical position, which can help identify patients with MSA
- Single photon emission computed tomography (SPECT) scan: Assesses chemical and energetic measures of the brain and how it
is performing, for patients who might have corticobasal degeneration
Once the evaluation is complete, our
Movement Disorders team meets with each patient to discuss the diagnosis and treatment options.
