In Valencia, Spain, a British investigator asserted that l8 million people in the whole world suffer at present form Alzheimer’s disease, although he predicts that this “figure will increase up to 34 million by 2005.” In a recent conference entitled ALZHEIMER’s PATHOGENESIS IS DERIVED FROM THE STUDY OF THE BRAINS OF MICE AND HUMANS this neuropathology was described as macro and microscopic structural changes typical of Alzheimer's disease. The relation among changes and development of the disease symptoms in humans was also determined. The Welsh professor admitted the difficulties scientists find on the mechanisms of this disease by expressing that “one of the greatest problems we scientists face is its diagnosis itself”.

“The symptoms are produced towards the end of the disease, when it is in an advanced stage, so one cannot investigate if the disease is not detected before and the most important thing to do would be to identify and study it from its very beginning. The symptoms are well known once the disease is developed, but not so in the process of its development” and added: “Alzheimer’s disease is a neurodegenerative disease – the brain is degenerated and it cannot return to its initial stage or can neither recover. It has a great capacity to regenerate from its lesions, but in the case of Alzheimer’s disease, when one detects the sickness, it is already too late,” formulated the Welsh professor.
