It has been observed that some substances, especially a substance produced from the heroin industry and abbreviated to MBT, can lead to acute Parkinson’s. Of course, this theory holds that even the unknown Parkinson’s disease is caused by the accumulation of exposure to substances Certain factors are present in the surrounding environment but are not yet known. One of the facts supporting this theory is that the disease is more likely to develop as the age of infection is 60 years
It is also supported by this theory that there is a weak correlation between Parkinson’s disease and exposure to some substances in the surrounding environment such as pesticides and sawdust, That people who suffered from a head injury have an opportunity to get the disease more than those who have not been infected in the head four times, and found that some drugs, especially antipsychotic drugs increase the risk of infection because it reduces the amount of dopamine, An increase in the dopamine receptor increases the risk of the disease because it reduces the sensitivity of these receptors to dopamine.
