How is Parkinson's disease (PD) diagnosed?PD is traditionally diagnosed clinically.
A movement disorder neurologist like Dr. Jennie Davis has specialized training to recognize the cardinal signs and symptoms of this disease. A detailed medical history and thorough neurological exam are often sufficient for a movement disorder specialist to make the diagnosis of PD.
Dr. Davis will look for the 4 cardinal signs of PD: resting tremor, rigidity (stiff muscles), bradykinesia (slow, irregular movements), and postural instability (imbalance). 2 of these signs are necessary to make the diagnosis of Parkinson's disease.
Supporting non-motor symptoms like active dreams (REM behavior disorder), decreased sense of smell and constipation are helpful to support this diagnosis, but are not necessary to make the diagnosis.
When the diagnosis is uncertain adjunct tests like a DaTScan or SynOne skin biopsy can help confirm the diagnosis.
