Dr. Advait Kulkarni (Neurologist) neurologist near me neurologist in bengaluru #neurologistinbengaluru #neurologistnearme Diagnosis A doctor trained in nervous system conditions (neurologist) will diagnose Parkinson's disease based on your medical history, a review of your signs and symptoms, and a neurological and physical examination. Neurologist may suggest a specific single-photon emission computerized tomography (SPECT) scan called a dopamine transporter (DAT) scan. Although this can help support the suspicion that you have Parkinson's disease, it is your symptoms and neurological examination that ultimately determine the correct diagnosis. Most people do not require a DAT scan. Neurologist may order lab tests, such as blood tests, to rule out other conditions that may be causing your symptoms. Imaging tests — such as an MRI, ultrasound of the brain and PET scans — also may be used to help rule out other disorders. Sometimes it takes time to diagnose Parkinson's disease. Neurologist may recommend regular follow-up appointments with neurologists trained in movement disorders to evaluate your condition and symptoms over time and diagnose Parkinson's disease.
