Parkinson disease is also known as Pallidotomy.It’s a disease of the nervous system and it’s based on trembling of the arms and legs.Parkinson is caused by the loss of the brain cells of the substantia nigraBecause of the loss of these cells,less dopamine is produced and because of that,the striatum(the area that co-ordinates movement) doesn’t work properly.A study shows that one person in every 500 is infected a year with Parkinson disease.People could get this disease by exposing theirselves on certain risks such as:
1.pesticide and herbicide exposures.
2.rural living.
3.previous head injury.
4.impairment of smelling capacity.
5.obssesive personality.
6.severe emotional trauma.
7.severe emotional stress.

This disease is difficult to be recognised in it’s early stages.Because it has no regular symptoms,the doctors find it difficult to diagnose Parkinson disease in it’s early stage.Early treatment may help so that the disease won’t spread that quickly.

These are some early symptoms of parkinson disease :
a.difficulty of moving and slowness.These are probably the first symptoms of Parkinson disease.
b.a tremor when the body is relaxed,usually on resting.Tremors often come when the person is awake.
c.a response to the drug levedopa,the first treatment in Parkinson disease.
d.bradykinesia-movement initiated slow.The person finds it hard to move from a resting position.The person often tends to stop suddenly.
e.poor balance and unstable walking.An affected person with Parkinson disease walks very hard and very slow.
Other symptoms may include:expressionless face,reduced manual dexterity,handwritting difficulties,drooling,sleep problems,urination at night,depretion and anxiety,constipation and difficulty in turning in bed at night,weakness of face and throat muscles.The person with Parkinson disease finds it hard to talk or to swallow,and because of the disease the person may choke or drool.

Early symptoms of Parkinson disease also include stiff fingers or shoulder or stiff muscles.Stiff muscles is a very common Parkinson symptome.Also there are symptoms like:decreased dexterity and coordination,cramps in the muscles and joints,oily skin and increased dandruff,digestive problems,increased sweating,low blood pressure,freezing.,sleeping problems,mood problems and postural instability.
Symptoms usually affect on side of the body for the first or two years.The tremor can also affect the chin,lips and tongue.Tremors are reduced by complete relaxation or sleep.
In Parkinson the protein level is low.

A person which suffers from Parkinson disease cand become passive,dependent,confused.A sick person will not talk as much as it used to do.Parkinson disease can bring depressions on people as an effect of the disease.
Because the symptoms are not obvious all the time,people are recommended to take maybe an annual exam for Parkinson disease,exam which is called DATScan.Recent medicine won’t prevent or cure the disease but it can make life easier of a person who has this horrible disease.
