Remote delivery of cognitive behavioral therapy to patients with functional neurological disorders: Promise and...

Functional neurological disorders (FND) are an important source of healthcare utilization and morbidity. While there are no formal guidelines for treating these disorders, cognitive behavioral therapy (CBT) is emerging as a safe and effective treatment. Currently, there is a global shortage of CBT providers, with only a small subset trained in and comfortable with treating patients with FND. We highlight four types of remote CBT delivery to patients with FND to alleviate the access obstacle: workbooks, internet-guided CBT, app-based CBT, and teletherapy. CBT workbooks and teletherapy have been studied in FND, with preliminary studies suggesting efficacy; internet-guided CBT and app-based CBT have not but have been effectively used in patients with psychiatric disorders, particularly depression, anxiety, and post-traumatic disorders. As these disorders are often comorbid and share overlapping neurobiology with FND, internet-guided CBT and app-based CBT represent promising delivery options of CBT for FND. Although remotely-delivered CBT is unlikely to replace in-person CBT and there are technical and logistical challenges to overcome prior to widespread deployment, it holds promise as an adjunct treatment when in-person CBT is inaccessible. We propose a rational approach to future allocation of remote CBT treatment options and highlight important research gaps to bridge beforehand.
