Multi-Photon Laser Technique Shows Potential for Treating Alzheimer's, Parkinson's
5 November 2013
A breakthrough in the field of laser technology could prove the cornerstone for a revolution in the way certain brain disorders such as Alzheimer's, Parkinson's and Creutzfeldt-Jakob disease are treated and cured, Bio-Medicine reports.
The discovery is a result of work by researchers at Chalmers University of Technology in Sweden and Poland's Wroclaw University of Technology who used multi-photon laser technique to discern clumps of the proteins believed to be responsible for these diseases from the well-functioning proteins in the body. Once these malfunctioning proteins are detected and removed, these brain disorders are practically cured. Until now, the difficulty has been in identifying and removing the aggregates, but no one has talked about using only light to eradicate such diseases, Piotr Hanczyc at Chalmers University of Technology said. The researchers believe that this entirely new approach could be a major step forward in the research into these diseases. This is a new way of distinguishing harmful protein structures using just laser light, he added.
The researchers are hopeful that malfunctioning proteins could be removed using photo acoustic therapy, which is already deployed in tomography.
Currently, amyloid protein lumps can be detected and removed using chemicals, but these chemicals are extremely toxic and could further damage the health of the patient. The multi-photon laser technique would eliminate the need for chemical treatment and would also make surgery unnecessary. The discovery could pave the way for removing the malfunctioning protein without affecting the surrounding tissue.
