Voice and highlight the eye disease years before manifesting Serious diseases such as Parkinson can be diagnosed as ten years before they happen. The findings, which also affects Alzheimer's, was presented at the last meeting of the Society of Nuclear Medicine in Salt Lake City. The observation point is the diagnostic optic nerve: examining the PET (positron tomography) to 200 elderly, both healthy and sick, the researchers found that among its fibers accumulate clusters of beta-amyloid protein, long before they spread in the brain. Their presence in the optic nerve would increase 13-fold risk of developing the disease. In addition to this important discovery, early diagnosis could be facilitated by the development of a platform. In this direction moves the two-year research project "Parkinson Informative System", an Italian project promoted by the bioinformatics BioDigitalValley Pont Saint Martin (Aosta), in collaboration with the University of Insubria and the financing of the Autonomous Region Valle D'Aosta. The project was implemented thanks to the most significant appropriation of funds never been in Italy for research on Parkinson. "The goal, as explained by Dr Enrico Bucci, scientific director of BioDigitalValley - is to obtain markers of disease targets, ie measurable biochemical parameters which can take care to anticipate a pre-symptomatic, with clear benefits for patients ". Going forward in the search, you can groped to identify potential diagnostic markers and therapeutic, in a shorter time than today, and for Parkinson's disease than for other neurodegenerative diseases.
Meanwhile, the latest report on the causes of the disease published in Science Traslational Medicine, confirms that the origin of the disease there would be disruption of the relationship between mitochondria, the powerhouses of cells, and neurons, resulting in a lack of supply of energy for the neurons themselves.
