Could a LASER zap away Alzheimer's, Parkinson's and even CJD? -

Lasers could be used to cure diseases such as Alzheimer's and Parkinson's, a new study suggests.
Researchers say they have made a discovery that may allow them to eradicate Alzheimer's disease, Parkinson's disease and Creutzfeldt-Jakob disease using light therapy.
Swedish and Polish scientists have discovered it is possible to distinguish clumps of the proteins believed to cause the diseases from the well-functioning proteins in the body by using a laser imaging technique.

Dr Piotr Hanczyc, of Chalmers University of Technology, in Sweden, said: ‘Nobody has talked about using only light to treat these diseases until now. 
‘This is a totally new approach and we believe that this might become a breakthrough in the research of diseases such as Alzheimer's, Parkinson's and Creutzfeldt-Jakob disease. 
‘We have found a totally new way of discovering these structures using just laser light.’
If the protein clumps are removed, the disease is, in principle, cured. The problem until now has been detecting and removing the clumps.

The researchers now have high hopes that light technique, which is already used for scans such as CT scans, may be used to remove the malfunctioning proteins. 
Today amyloid protein clumps are treated with chemicals, both for detection as well as removal. These chemicals are highly toxic and harmful for those treated.
With the use of a laser, the chemical treatment would be unnecessary, as would surgery.
