Patent suggests a future Apple Watch may help doctors treat Parkinson's

A newly discovered patent suggests that a future Apple Watch might be able to help doctors monitor the symptoms of Parkinson's patients. As a result, they'd also be able to improve their treatments, too,

US patent number 20190365286 describes the feature, along with Apple's reasoning for adding it in the first place.

"There are an estimated 600,000 to 1 million cases of Parkinson's Disease in the United States and 60,000 new cases are diagnosed each year," says the filing as it describes the symptoms suffers deal with. "Symptoms of PD include... tremor and dyskinesia. Dyskinesia is an uncontrollable and involuntary movement that can resemble twitching, fidgeting, swaying or bobbing."

Unfortunately, the treatment of Parkinson's can also cause the symptoms to change and worsen, requiring the medication to be altered. The problem is that doctors rely on clinic-based tests and patient reports in order to make those calls.

"A patient's quality of life is largely dependent on how precisely clinicians titrate and schedule the patient's medications to minimize the patient's symptoms. This is a challenge for clinicians because each patient has a different combination of symptoms that can change and become more severe over time. Also, in any given day the symptoms may fluctuate based on medications, food intake, sleep, stress, exercise, etc."

The patent describes a series of sensors that will detect movement. That data will then be analyzed by the Apple Watch using the Unified Parkinson's Disease Rating Scale (UPDRS). By doing that, the data can be collected more accurately and it doesn't require the patient to keep tabs on their symptoms in order to better their treatment.

While the most obvious use for this technology would be in an Apple Watch – an image attacked to the patent shows an Apple Watch, too – Apple doesn't specify that this would be Apple Watch-only. That could potentially mean that an iPhone could be used, as could the Apple ring that we saw a patent for recently, too.
