Senile dementia and Parkinson's disease linked

Senile dementia and Parkinson's disease linkedVarious severe diseases of the brain can have a single cause. American scientists have found common elements in the mechanism of development of Parkinson's disease and Alzheimer's disease, or senile dementia. This may explain why patients with the same disease often show symptoms of the other. The scientists believe that the cure for one disease may be effective in another. Researchers, in particular Professor, Virginia Lee (Virginia Lee) from the medical faculty of the University of Pennsylvania, studied two chemical substances that play a key role in the development of the two diseases of the brain. We are talking about the Tau protein, which in large quantities are found in Alzheimer's disease, and alpha-synuclein, which in Parkinson's disease becomes toxic and affects the brain. Scientists have found that these chemical compounds can interact, forming amyloid, which is a cause of brain damage as in Alzheimer's disease and Parkinson's disease. "This is a fundamental discovery helps explain why patients with the same disease may be signs of another," said Professor Lee. "Open interaction between the two proteins suggests that drugs designed to direct or indirect suppression of one of the forms of amyloid deposits can be effective in the treatment of other injuries associated with amyloid," said co-author of the study published in the journal Science, Benoit Giasson (Benoit Gaisson).
