A safe and affordable treatment to slow the advancement of Parkinson's dementia has emerged – in the form of a commonly available cough syrup that's already being studied for its positive effect on other degenerative diseases. Researchers at St Joseph’s
Health Care London's Lawson Research Institute have released the results of a 12-month clinical trial investigating the cough medicine Ambroxol and its potential to slow Parkinson's-related dementia.
In the study, 55 patients with Parkinson’s disease dementia (PDD) were ... given either a daily dose of Ambroxol or a placebo and had their memory, psychiatric symptoms and the brain-damage blood marker GFAP monitored. “Our goal was to change the course of Parkinson’s dementia,” said study lead Dr Stephen Pasternak, a cognitive neurologist at Lawson. “This early trial offers hope and provides a strong foundation for larger studies."
