The Functionality, Evidence, and Privacy Issues Around Smartphone Apps for the Top Neuropsychiatric Conditions.

OBJECTIVE: There are more than 325,000 health-related smartphone applications (apps) on the market. To better understand the apps currently on the market for the five most disabling neuropsychiatric conditions, the authors conducted a study investigating their intended uses (target population and intervention), the data collected, and any privacy policies. METHODS: This was a cross-sectional study of apps for the five most disabling neuropsychiatric conditions per the World Health Organization: stroke, migraine, depression, Alzheimer's disease and dementia, and anxiety. Up to 15 apps in the U.S. Google Play and Apple app stores were selected based on the following prespecified inclusion criteria: the app appeared in the top 50 search results, offered intervention or tracking capabilities, and listed the condition in the app title or description. Exclusion criteria were <$5.00 to purchase, solely motor versus cognitive-based intervention, or designed for use by caregivers or health care providers. Data abstracted included function, behavior change rewards, and information about intervention, privacy policy, and payment. RESULTS: Eighty-three apps were reviewed (stroke, N=8; migraine, N=25; Alzheimer's disease and dementia, N=8; depression, N=7; anxiety, N=14; apps targeting depression and anxiety, N=21). Sixty-nine percent of apps had an intervention component, 18% were deemed evidence based, 77% had a privacy policy, 70% required payment for access to all features, and 19% rewarded user behavior changes. CONCLUSIONS: Most apps on the market targeted migraine, depression, and anxiety and contained interventions, although most of the interventions did not appear to be evidence based. Additionally, although most apps had privacy policies, lay people may have difficulty understanding these policies due to their complexities.

Privacy Issues in Smartphone Applications: An Analysis of Headache/Migraine Applications.

BACKGROUND: Headache diaries are a mainstay of migraine management. While many commercial smartphone applications (apps) have been developed for people with migraine, little is known about how well these apps protect patient information and whether they are secure to use. OBJECTIVE: We sought to assess whether there are privacy issues surrounding apps so that physicians and patients could better understand what medical information patients are providing to the app companies, and the potential privacy implications of how the app companies (and other third parties) might use that information. METHODS: We conducted a systematic search of the most popular "headache" and "migraine" apps and developed a database of the types of data the apps requested for input by the user and whether the apps had clear privacy policies. We also examined the content of the privacy policies. RESULTS: Twenty-nine apps were examined (14 diary apps, 15 relaxation apps). Of the diary applications, 79% (11/14) had visible privacy policies. Of the diary apps with privacy policies, all (11/11) stated whether or not the app collects and stores information remotely. A total of 55% (6/11) stated that some user data were used to serve targeted advertisements. A total of 11/15 (73%) of the relaxation apps had privacy policies. CONCLUSIONS: Headache apps shared information with third parties, posing privacy risks partly because there are few legal protections against the sale or disclosure of data from medical apps to third parties.

Wearables for Neurologic Conditions: Considerations for Our Patients and Research Limitations.

PURPOSE OF REVIEW: In 2019, over 50 million Americans were expected to use wearables at least monthly. The technologies have varied capabilities, with many designed to monitor health conditions. We present a narrative review to raise awareness of wearable technologies that may be relevant to the field of neurology. We also discuss the implications of these wearables for our patients and briefly discuss issues related to researching new wearable technologies. RECENT FINDINGS: There are a variety of wearables for neurologic conditions, e.g., stroke (for potential arrhythmia capture), epilepsy, Parkinson disease, and sleep. Research is being performed to capture the risk of neuropsychiatric relapse. However, data are limited and adherence to these wearables is often poorly studied. SUMMARY: The care of neurology patients may ultimately be improved with the use of wearable technologies. More research needs to examine efficacy and implementation strategies.
