Parkinson's Disease Overview

What is Parkinson's Disease?

• It is a progressive neurological condition of the brain.
• Defined by the degeneration of dopamine-producing neurons in the substantia nigra of the midbrain.
• It disrupts the normal balance between dopamine and acetylcholine in the basal ganglia.
• Impedes the extrapyramidal tract controlling movement.
• Results in a loss of motor control, tremor, rigidity, and bradykinesia.

Symptoms

• Slow movement
• Memory problems
• Tremor
• Reduced balance
• Rigidity
• Depression

Causes

• There is a reduction in nerve cells within the substantia nigra, part of the basal ganglia structure of the brain.
• This reduction leads to a decrease in the chemical, dopamine, producing the symptoms of Parkinson's.

Risk Factors

• Genetics
• Pesticide exposure
• Being over 50
• Being male

Diagnosis

• There is no exact test to diagnose Parkinson's, and many other conditions may have similar symptoms.
• Diagnosis is typically based on the presentation of known symptoms, a DaT scan, MRI scan, or SPECT scan.

Treatment

• There is no cure.
• Treatment options focus on relieving symptoms.
• Treatments include physiotherapy, speech and language therapy, medication (Levodopa or dopamine agonists), and psychological methods.
