Ongoing degenerative changes of pigmented neurons in brain are the essence of Parkinson’s disease. Consequently, it leads to deficiency of dopamine which is a neurotransmitter in substantia nigra and striatum. Gradually, disease process involves other brain structures and Lewy bodies can be observed in changed tissues.
It is currently believed that depression may be caused by improper functioning of immune system cells in brain. The scientists from The Hebrew University of Jerusalem claim that treatment of depression may be revolutionized by the use of new psychotropic drugs. The results of the analysis were published in Cell Press in the section Trends in Neurosciences. Read full text »
The scientists from New York discovered that functional nuclear MRI scan allows to monitor patient’s response to antipsychotic drugs used schizophrenia. The results were published in The American Journal of Psychiatry.
Alzheimer’s disease is the most common condition of the central nervous system responsible for the symptoms of dementia. This defect is clearly associated with age and more often manifests itself in women. The reason of the disease is not fully understood. It is known that the pathogenesis involves accumulation of insoluble protein Aβ in the brain. Recent years brought growing interest in Alzheimer’s disease and scientists have put forward assumptions that the HSV1 virus infection may be associated with this condition. Researchers from Umea University in Sweden have conducted a prospective study in order to prove this relationship.
Scientists from the University of California, San Diego Health Sciences and Allen Institute for Brain Science discovered that six layered structure of cortex is focally disrupted in autistic patients. Their results suggest that autism begins long before birth whereas environmental factors influence further disease development. Read full text »
Research conducted by American scientists contributed to the discovery of how does human brain process sounds. This knowledge may be practically applied in music therapy – dynamically developing treatment method used in increasingly broader group of diseases.
Sclerosis multiplex is the most common inflammatory demyelinating disease of the central nervous system. Scientists have been looking for its reasons for years since it would allow to devise specific medication. Among supposed etiological reasons are genetic burdens, autoimmune reactions and environmental factors. Read full text »
It has been assumed for years that Parkinson’s disease, which is a degenerative disease of a central nervous system arising from dopamine deficiency, may have other causes than genetic ones. It was thought that risk factors may come from external environment as in the case of many other diseases. Read full text »
The latest research compared survival of patients with diagnosed terminal brain tumour who were treated with standard methods and with the use of experimental vaccine developed individually for every patient. The results have shown that the use of the vaccine brings very beneficial effects and prolong life of the patients.
Professor Keith Muir from Glasgow University claims that stem cells are a real chance for treatment of patients after a stroke. For years he and his team have been conducting research on usage of this method in practice. According to BBC he is currently trying to administer stem cells to the patients. The results turned out to be surprisingly good. Read full text »
