Parkinson Disease

Parkinson Disease

Parkinson disease is a neurological movement disorder that affects the movement of the body.

It is a neurological disorder with increasing age.

Smooth and the coordinated movement of muscles are possible by a neurotransmitter in the brain called dopamine.

Dopamine the substance produced from the Substantia Nigra for the smooth coordination of movements of the body.

Parkinson Disease



In Parkinson disease with increasing aging process, the cells of the Substantia Nigra start to die, so the production of dopamine reduces and around 60-80 per cent production of dopamine is reduced and the symptoms of Parkinson start to appear.

The symptoms increases along with the age and there is no cure for the Parkinson disease which is chronic and worsen over time.


Causes of Parkinson Disease

The exact is unknown but it has been estimated with the genetic and environmental causes.

Low level of dopamine increases the severity of symptoms.

Men are more prone as compared with the females.

Whites are more likely to get more than blacks.

Family history also play an important role.

Exposure to toxins may increases the chances of Parkinson disease.

Head injury is also included in the development of Parkinson disease.

Ø 

        Stage 2

  • This is the moderate stage having joint stiffness, tremors, facial expressions, trembling, muscle weakness.
  • Changing of postural deformity and gait is start noticing in this stage.

Ø 

        Stage 3

  • At this stage symptoms reaches to the middle stage. Movements become slower, assistance in some conditions, balance issues are more common in this stage.
  • In this stage person try to complete all the task independently without much assistance.

  • Musculoskeletal deformities such as kyphosis, forward bending, stiffness of back, chorea movements, dystonia are more common in this stage.


Diagnosis of Parkinson disease

The diagnosis of PD is based on the

  • Physical history
  • Neurological examination
  • Health history

There is no particular test for the diagnosing of PD.

  •       MRI scan
  •       CT scan
  •       X-ray
  •       Blood test.
  •       Nerve conduction velocity (N C V)
  •       ECG

 

Treatment of Parkinson Disease

Parkinson disease is the neurological disorder which can be treated by changing the lifestyle, rehabilitation therapies, and medications.

  • Adequate rest
  • Healthy diet
  • Regular exercises
  • Physiotherapy
  • Occupational therapy
  • Speech therapy
  • Medications-
        • Levodopa
        • Dopamine agonist
        • Anticholinergic drugs
        • Antidepressants
