The dependence of mental diseases on the bad environment was shown in many investigations. High levels of epilepsy, schizophrenia, Parkinson, Huntington, Alzheimer and other diseases were found in areas with pollutions of ground, water or air by toxic substances. It is known that some mental diseases are the result of the disturbance of the neurotransmitter balance. For example, Parkinson`s disease is connected with the lack of the dophamine, schizophrenia with the lack of GABA in cortical regions, epilepsy with an imbalance between excitatory and inhibitory neurotransmitters and so on. The influence of neurotoxins can cause a neurotransmitter imbalance also by the destruction of neurons or by the disturbance of the brain stem cell s migration and neurogenesis.
Some mental diseases could be caused by the destruction of genes in sex chromosomes, especially in the man s Y-chromosome. It was shown, that ultraviolet, X-ray and toxic substances could lead to mutations and deletions of genes. The number of men with the Turner s syndrome (absence of one sex chromosome) has been increased more than twice during last 50-60 years.
So, people must take care of the environment, control the industry, decrease the level of pollution, be careful with food and drugs.
Destroying the nature people destroy themselves.
