A new method has been found out by scientists to determine the severity of Parkinson's disease. They noted that if the speech patterns are studied then the symptoms of the disease can easily be monitored which will end up saving a lot of valuable time and money for the health authorities resulting in reduced burden on the patients.

During the study the American and British scientists examined around 6,000 speech recordings from almost 42 Parkinson's patients and recorded data in the form of algorithms to make an estimate of how worse were the symptoms.

The results which were published in the Royal Society's journal Interface suggest that these algorithms were very close to estimates made by many medical experts.

Working on the research, Max Little of Britain's Oxford University, said "Currently, monitoring requires frequent visits to hospital where people with Parkinson's are physically examined by expert clinicians in order to assess their symptom severity, putting a strain on both patients and hospital resources."

He added that this research gave proof that impaired speech is very closely associated with the overall severity of other Parkinson's disease symptoms.
