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.
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 perct 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-
