Future of C-L Psychiatry
Biosignals are continuous human physiology data that can be noninvasively measured and exploited to diagnose and treat disease, and to monitor cognitive states in order to optimize health and performance. Biosignals may include vital signs and autonomic nervous system indices, cerebral blood flow (CBF), galvanic skin response (GSR), actigraphy, electromyography (EMG), and electroencephalography (EEG), among others. Traditional means of measuring and modulating these biosignals have existed for decades. However, with advancements in miniaturization, portability, user-interfaces, and novel data analytics, it is now possible for medical providers, patients, and the general public to collect, process, and interact with biosignals in real-time.
In this symposium, Drs. Shinozaki, Hunter, Merideth, Pinchotti, and Quinn will present important research advancements in the area of biosignals that have the potential to transform the management of symptoms, illness, and health maintenance for CL psychiatrists.
Dr. Gen Shinozaki will present his ongoing years-long work on the use of limited channel bedside EEG and machine learning to predict delirium occurrence, length of stay, and all-cause mortality in patients in the general hospital.
Dr. Michael Hunter will discuss the uses of heart rate variability (HRV) biofeedback and neurobiofeedback for mindfulness meditation and stress reduction, and describe his specific work employing these techniques to improve resilience in service members in shipboard environments.
Dr. Flannery Merideth will review the literature on bispectral index monitoring (BIS) in anesthesiology and psychiatry, before reporting the latest findings from a multi-site study of BIS with density spectral array (DSA) to identify delirium and catatonia. Dr. Dana Pinchotti will then describe her pilot study of BIS-DSA for early screening and identification of cognitive impairment in the ambulatory clinic setting.
Dr. Davin Quinn will discuss the technology of functional near-infrared spectroscopy (fNIRS) and its related clinical uses in measuring peripheral blood oxygenation (pulse oximeter) and cerebral blood flow (cerebral oximeter). He will then present findings from a pilot study of cerebral blood flow measured with whole-head fNIRS during a working memory task and brain stimulation.
Participants will be provided ample time to discuss the technologies introduced, ask questions, and try one of the wearable biosignal monitors.
