Parkinson’s Disease

By Devin Cornford



Parkinson's disease (also known as PD) is a degenerative disorder of the central nervous system that often impairs the sufferer's motor skills, speech, and other functions.

Parkinson's disease belongs to a group of conditions called movement disorders. The primary symptoms are the results of decreased stimulation of the motor cortex by the basal ganglia, normally caused by the insufficient formation and action of dopamine, which is produced in the dopaminergic neurons of the brain. PD is chronic and progressive.


Shuffling gait.

Tremors of the limbs.

Stooped posture.


Some people also experience cognitive impairment such as dementia.




Bradykinesia (slow movement)

Akinesia (loss of movement)

Difficulty with balance and walking.

Secondary symptoms



Weight loss

Sleep disturbances


Difficulty swallowing and speaking

And the worst of all difficulty with sexual performance.


There is no cure for Parkinson’s disease!

There are however some drugs that slow the progress.

Most treatment revolves around how bad the symptoms are. Minor symptoms are generally not treated.


Medication selection and dosage are tailored to the individual.

Levodopa is a substance normally found in the body in limited amounts, and is usually the first medication prescribed. Levodopa PO can be converted by the body into dopamine the body needs.

Deep Brain Sitmulation (DBS) targets areas of the brain where uncontrolled movements originate. The targeted region is inactivated by an implanted electrode. The electrode is connected by a wire running beneath the skin to a stimulator and battery pack in the patient's chest.


Parkinson's disease is a chronic disorder that requires broad-based management including patient and family education, support group services, general wellness maintenance, physiotherapy, exercise, and nutrition. At present medications or surgery can provide relief from the symptoms of Parkinson’s.

Progressive Supranuclear Palsy (PSP)

PSP is often misdiagnosed as Parkinson’s

Some misdiagnosed cases are not figured out until autopsy.

signs and symptoms are very similar to Parkinson’s. The one difference that I know of is difficulty swallowing is one of the main symptoms

Died from complications of PSP in 2003.


People who suffer from Parkinson’s or PSP do not die from the disease itself.

Most common cause of death is aspiration pneumonia. Due to loss of muscle tone in the facial muscles.
