Parkinson disease and its effects on muscle control essay sample


Muscle control is a great problem for patients with Parkinson’s disease. This neurological disorder is caused by an impairment of nerve cells in the brain area called the substantia nigra and it is characterized by diverse uncontrollable movements.  As the disease progresses, movements intensify or cause immobility. Tremor is a well-recognized symptom of Parkinson’s, however, a mere hand shaking can happen to healthy people as well. There is a wider range of visible symptoms that point out to Parkinson’s as they all are linked to problems with movement.

Slow movement or bradykinesia is one of the early signs of Parkinson’s disease. Muscles cannot quickly respond to brain impulses because the condition destroys cells that produce dopamine, which is the main neurotransmitter. The lack of dopamine makes patient’s movement uncontrollable without any other reason. Poor transmission of signals usually affects all groups of muscles; not only shuffling walk but also a mask-like face indicate that a person cannot properly move.

Poor balance frequently goes along with slow movement because of the same reason. People with Parkinson’s frequently risk falling while they walk. They have a stooped posture, and move like senile people. Parkinson’s disease starts progressing in patients older than 60, but it is quite visible that these people are not old enough to suffer from such impairments.

Because of the constant tremor and tension, patients frequently experience pain in muscles. People can neither move nor relax properly which makes them very depressed. Physical pain is one of the nastiest symptoms of Parkinson’s because patients cannot enjoy their life.
