The article says: Doug Brown, director of research at the Alzheimer’s Society, cautioned that the technique is not something that can be translated into a procedure that is safe for the estimated 44 million people worldwide with dementia just yet. which makes clear that the blue light technology is very far from being a cure for Alzheimer.

On the other hand, Dr Dale Bredesen has already in a very small study with 10 persons, reversed Alzheimer in 9 of 10 patients. A followup study with 100 persons is not yet finished but preliminary results show "similar results". The work of Dr Bredesen is mostly unknown but this will likely change in the near future. The work of Dr Bredesen may start a revolution since he does not use a traditional medicine but a holistic approach which basically fights inflammations at all levels possible.
