Riding a bike ability could be key to diagnosing certain forms of Parkinson’s disease after doctors determined that it is far cheaper and more accurate of the various tests.

A team of researchers from the Netherlands, explains how those with standard Parkinson’s disease are more likely to still can not ride a bike, as opposed to those with atypical Parkinson’s disease who can not.

Only four percent of those with the standard form of Parkinson’s disease have not been able to ride a bike, compared with those who have an atypical form of the state where more than half could not ride a bike.

Atypical form of Parkinson’s disease are more likely to include cognitive and memory problems, and tremors associated with the standard form of the disease and may require different treatment.
