Experimental Parkinson’s drug ‘lifted brain fog’

A British woman diagnosed with Parkinson’s disease almost 20 years ago said a fog lifted in her head after corrective genes were injected into her brain.

Sheila Roy, 66, is one of six people in the world who received the radical treatment, which in her case has allowed her to think clearly and quickly again.

Sheila, from Bedfordshire in England, is a patient of Roger Barker of the University of Cambridge.
