. Parkinson's is a progressive, neurodegenerative disorder of the melanin-containing-dopaminergic neurons in the anterior part of the substantia nigra pars compacta.
Pars compacta are involved in tonal modulation.
Dr. Mobeen Syed discusses the prognosis of the disease.
The condition usually worsens over an average of 15 years.
The rate of progression and its course varies among patients. The course is relatively benign in patients with little disability after twenty years, and maybe more aggressive among others who may be severely disabled after ten years.
The causes of death in patients with Parkinson's disease are infections and postural instability.
The most common cause of death in patients with Parkinson's disease is pneumonia because the disease impairs patients' ability to swallow, putting them at risk for inhaling or aspirating food or liquids into their lungs, leading to aspiration pneumonia.
The cause of death in patients with Parkinson's disease can also be gait instability, which causes falling and death of those patients.
Dr. Mobeen also describes the clinical symptoms of Parkinson's disease.
Agonists and antagonists are all tense; rigidity occurs. With rigidity, there is extra pressure on the joints, so there is joints pain.
Rigidity is of the cogwheel type due to increased extensor muscle load.
In the case of Parkinson's disease, static tremor is present all the time and is of pill-rolling type.
Expressions are absent (masked face due to the loss of tonal modulation).
The gait of Parkinson's disease patient is a festinating gait.
Patients feel hallucinations, and they keep acting out their dreams.
The following topics have discussed:
* Prognosis of Parkinson's disease
* Clinical symptoms of Parkinson's disease
* Cogwheel rigidity
* Pin-rolling tremors
* Absence of expressions
* Festinating gait ...
