Diagnosing Parkinson’s

A neurological examination, medical history, and the exclusion of other health conditions that could be causing the same symptoms are all part of the diagnosis process for Parkinson’s disease. Although there isn’t a single, conclusive test for Parkinson’s disease, a number of methods are employed to get a diagnosis.

Medical History and Examination Patient History

The neurologist will conduct a detailed examination to evaluate the patient’s motor skills, reflexes, muscle tone, balance, and coordination.
The presence of tremors, bradykinesia, rigidity, and postural instability will be evaluated.

Imaging Tests

MRI and CT scans: Computed tomography (CT) and magnetic resonance imaging (MRI) scans can help rule out other disorders like strokes or brain tumors that may cause similar symptoms, but they cannot be used to directly diagnose Parkinson’s disease.

DaTscan

A DaTscan is an imaging test that can help foresee the dopamine transporter in the brain. It is used to distinguish Parkinson’s disease from other movement disorders, including drug induced Parkinsonism and tremors. However, it is not a definitive test for Parkinson’s and is typically used in conjunction with clinical evaluation.

Trial of Parkinson’s disease Medications

Levodopa Response Test: one way to support a diagnosis of PD is to observe the patient’s response to Levodopa, a medication that increases dopamine levels in the brain. Levodopa may indicate Parkinson’s disease if the patient’s symptoms considerably improve after taking it.

Differential Diagnosis

A list of possible conditions that share the same symptoms as described by the patient

Multiple System Atrophy (MSA)

It is an uncommon neurological condition that combines autonomic dysfunction, including high blood pressure, along with symptoms resembling Parkinson’s disease.

Progressive Supranuclear Palsy (PSP)

A condition that can cause symptoms resembling Parkinson’s disease, like bradykinesia and stiffness, but is distinguished by difficulties with eye movements and balance.

Corticobasal Degeneration (CBD)

Another rare condition that causes asymmetric Parkinsonian symptoms but is characterized by more severe cognitive and motor symptoms.

Drug-induced Parkinsonism (DIP)

A condition that shows asymmetrical Parkinsonism and tremor at rest, making it difficult to differentiate from PD.
