Researchers have uncovered a potential new treatment for Alzheimer's disease.
A team from the Institute for Neurological Research in California claim that injecting a drug called etanercept into patients' necks could improve brain cell communication.
Initial tests have been carried out on 50 participants with a response rate of 90 per cent.
The researchers claim to have noted a week-by-week improvement with each dose, reaching a plateau after three months.
Professor Edward Tobinick, who leads the research, said: "What we see is an improvement in their ability to think and calculate, their memory improves, their verbal ability improves, they find words easier, they seem happier, and we often also see an improvement in gait in those patients whose gait is affected."
According to the BBC, British scientists have advised that the medication be treated with caution.
This follows news that a new blood test which can give an early warning for Alzheimer's and Parkinson's is under development by Power3 Medical Products.
