A recent study aims to find the link between a person losing their sense of smell and the onset of Parkinson's disease, it has emerged.
The research, carried out by Northwestern Memorial Hospital and Northwestern University's Feinberg School of Medicine - both of Chicago - hopes to bring together reports of nasal functions shutting down in order to understand if this could be taken as a warning sign.
Dr Tanya Simuni, who is leading the study, said: "By utilizing smell testing in conjunction with other tests, we hope to develop a system that identifies the presence of Parkinson's before it develops into problematic symptoms."
She added that the study gave her team an "enormous opportunity" to help future generations of people affected by the condition, with therapy perhaps paving the way to a cure.
It was announced this month that a breakthrough in the treatment of Parkinson's disease could be close after Living Cell Technologies announced its development of cells may help in the rehabilitation of individuals.
