Chinese technology giant Tencent has teamed with London medical firm Medopad to research a system which uses a camera to capture the way patients move their hands in order to assess the severity of their symptoms.
Dr. Wei Fan, head of the Tencent Medical AI Lab, told the BBC: "We use the AI to measure the deterioration of Parkinson's disease patients without the patient wearing any sensors or devices."
A motor function assessment process can usually take more than half an hour, and the collaborative effort is to speed this up.
Medopad's smartphone technology could mean that patients are assessed within three minutes, possibly even without attending a hospital.
The London-based company explained it paired up with Tencent because of what they could offer.
Chief executive Dan Vahdat said: "Our ambition is to impact a billion patients around the world - and to be able to get to that kind of scale we need to work with partners that have international reach."
Parkinson's disease is an incurable condition, which causes parts of the brain to become progressively damaged over years.
