Transcranial electromagnetic treatment breaks down clumps of toxic proteins

This can free up previously-blocked nerve cells and help them function normally 

The quest for Alzheimer's treatments has for decades hit massive roadblocks 

A head device that zaps the brain with electromagnetic waves appears to have reversed the effects of Alzheimer's in a trial.

Eight patients with mild or moderate forms of the brain-destroying disorder took part in experimental transcranial electromagnetic treatment (TEMT).

It involved them wearing a skullcap of magnets which sent electric pulses to break down build-ups of proteins known to stop nerve cells working properly.
