A build-up of sticky proteins in the brain is a key hallmark of Alzheimer's , thought to be closely linked to the disease's progression. Now scientists have found a new way to clear these harmful clumps in the brains of mice and the eyes of fruit flies.

This potentially promising Alzheimer's treatment involves an oral dose of arginine , an amino acid already used as a medication for conditions including chest pain and high blood pressure .

The discovery was made by a team from Kindai University and Japan's National Institute of Neuroscience, who focused on the amyloid-beta plaques seen in Alzheimer's disease.

If the same results can be achieved in human brains, we may have another avenue for potentially tackling a key molecular symptom of Alzheimer's – in a safe and easily
