Pfizer ends research for Alzheimer’s, Parkinson’s drugs

The drug company – which makes the lucrative drug, Viagra – said it was ending its neuroscience research to focus on areas where it was strongest.

Alzheimer’s and Parkinson’s sufferers have been dealt a blow, with drug maker Pfizer deciding to end its research into the debilitating diseases.

Many sufferers and their families had felt new hope when the pharmaceutical giant began early-stage research, but the company has now decided to invest elsewhere.
