The healthcare sector across the world has shifted focus to the procedure undertaken for the treatment of Alzheimer's disease, which sees the patient suffering memory impairment.

The concerns have risen for the issue, as the doctors have realized that the symptoms of the disease are usually not very severely apparent. So, it gets difficult for them to detect the onset of the disease.

The brain develops barnacle-like piles of a protein fragment, amyloid beta, as the disease progresses.

Anthony Phillips, scientific director of neuroscience, mental health and addiction at the Canadian Institutes of Health Research, said that the up gradation of the procedure has long been awaited.

The overhaul guidelines were proposed at international Alzheimer's conference in Hawaii, in the beginning of this week.

Under the new set of changes, "preclinical Alzheimer's", "mild cognitive impairment because of Alzheimer's" and "Alzheimer's dementia" which are the three stages of the disease, will be treated in a redefined way.

The patients, who have entered the final stage of dementia, will now be treated with high perfection.

Gauthier, Director of the Alzheimer's disease Research Unit at McGill University, said that even those who haven't reported any signs of developing the disease should be made aware of the procedure of treatment and the onset of Alzheimer's disease.
