As you know, the brain and the central nervous system as a whole is controlled not only by all the processes occurring in the human body, but also the movements of the person.However, there is a group of people who do not have the ability to control their movements in full because they have Parkinson's disease . This disease is caused by a decrease in the level of chemicals in the human brain, which is responsible for motor function.This substance is produced in insufficient quantities because of dying off of nerve cells in the brain, which are a source of dopamine.Why nerve cells die, to date, with a precision not found.
more than two hundred years ago medicine has learned about this phenomenon as Parkinson's disease, its causes are unknown to this day.Moreover, this disease is likely to develop, and can provoke the occurrence of dementia.For example, more than 30% of people with this disease suffer from dementia, which is reflected in the slowing of thought processes, impaired memory and inability to concentrate.The reasons for this are the low standard of living and lacking care.Begins to manifest disease with tremor of muscles, increase muscle tone, slowness of movement and loss of balance, disorders of articulation.As for the later stages of the disease, it should be noted that patients begin to lose weight quickly, as the disturbed swallowing, breathing disorders also occur, while immobility for a long period of time can be observed deaths.
Today Parkinson's disease has several varieties:
- primary parkinsonism called idiopathic Parkinson's;
- secondary parkinsonism, which includes vascular, post-traumatic and other forms of the disease;
- Parkinson's syndrome, observed in the presence of hereditary diseases of the nervous system.
According to some medical research found that a low percentage of people suffering from Parkinson's, have close relatives suffering from the same disease.However, regarding Parkinson's disease, a description of the symptoms is present in those families in which several of its members are sick at the same time.Thus, the connection between the development of the disease and heredity have not yet succeeded.
considering the case of Parkinson's syndrome, medicine has been found that most illness appears around the age of fifty, after sixty years, the disease occurs in 1% of people aged over eighty years - from 4% to 10% of patients are menwho are under forty years.Parkinson's disease may also progress in childhood, but, unlike adults, children, it is slow and has a classic symptoms.It may be noted that the disease does not depend on the sex of the individual, his social status and residence.
At diagnosis, as Parkinson's disease, doctors conduct clinical observation of the patient, because today is not developed any medical tests that could establish the disease.Moreover, there are no pharmacological agents that are able to cure this disease, there are only drugs that only facilitate the course of the disease, and this treatment should be followed for life to prevent further symptoms.
Thus, currently there are many diseases that do not respond to treatment and their causes are not known to science.Among these diseases distinguish Parkinson's syndrome, characterized by movement disorders as a result of the withering away of nerve cells in the brain.Perhaps someday science will be able to explain this phenomenon, but today patients can only use drugs to reduce the symptoms of the disease.
