The Role of Digital Biomarkers in Psychiatry biomarkers digitalbiomarkers psychiatry health
Online digital biomarkers Biomarkers are biochemical and biophysical indicators of disease that can be measured and quantified, allowing physicians to give accurate diagnostic and prognostic assessments. The field of psychiatry generally lacks readily available data relating to biomarkers within the brain, being difficult to perform investigative analysis on or collect samples from living brains.
What is Telepsychiatry? In a proof of concept paper by Stieger et al. , a basic wrist-worn, button-activated accelerometer was utilized to conveniently submit data relating to the occurrence and intensity of symptoms based on the angle that the patient held their arm. Upon symptom occurrence, the patient needed to press a button and then hold their arm flat to indicate a low-intensity event or at any angle up to upright to report the most intense.
Most participants were able to reliably estimate a 45⁰ arm angle, sitting around an average in a bell curve, and also found the device convenient to wear and mostly non-interfering in their current activity, though trouble using the device while driving or engaged in other activities requiring attention was reported, along with a decline in device engagement throughout the trial.
In another pilot study by Li et al. , depressive feelings were monitored amongst the general and homosexual male community via Twitter and other social media platforms and dating apps by tracking the use of depressive language and post timing across hundreds of thousands of posts made by tens of thousands of users.
Brain implants Implants capable of monitoring and remotely reporting information relating to brain chemistry and function is a probability in the near future. Such interfaces are currently under early-stage investigation utilizing 3D-printed parts.
