Causes Of Parkinson’s Disease

As the studies have shown, Parkinson’s disease is caused by a lack of so called neurotransmitter dopamine (brain chemical), which controls movements and muscle activity of a person. Therefore, the main reason of developing of Parkinson’s disease in human body is considered a loss of specific brain cells, which can produce such neurotransmitter and support normal mental function. This damage can take place as a result of heredity, heroin abuse, or, in the majority of cases, aging. Medical causes of such malfunction of brain cells still remain unknown.

Thus, aging and getting old are the principal risk factors of Parkinson’s disease, as these factors are linked to certain damages of brain structure. There are also some additional factors, like frequent usage of some tranquilizers, some drugs with aluminum, inorganic iron, carbon monoxide, or other chemicals, long-term exposure to environmental toxins and harmful chemicals, drug usage, and many more. All these factors can provoke early symptoms of the diseases from Parkinson’s disease group.

There is no special medical test, which can directly identify Parkinson’s disease, although some lab tests may help to exclude the probability of wrong diagnosis. To diagnose this disease doctors have to carefully examine medical history, to interview patient and his/her family, and to support their hypothesis with usual medical tests, like blood pressure test, genetic test, brain scans (to check out activity of dopamine cells), X-rays, etc.

As a rule, above mentioned signs of Parkinson’s disease start appearing when 60-80 per cent of dopaminergic cells are lost. Within the time, the level of dopamine in the brain will go on decreasing; this will bring to damage of principal functions of human body and affect abilities and senses of the person. In order to avoid complications, individuals with Parkinson’s disease require a lot of care and attention, which must be focused on maintaining of emotional balance, stability and proper self-perception, and on avoiding worsening of the disease by attacks of Parkinson-related depression.
