accelerated lfr for bipolar patients during the covid-19 pandemic

Conditions: Bipolar Depression

Summary: the current study aims to assess the feasibility, acceptance and clinical outcomes of a practical high-dose lfr protocol, including tapering treatments and symptom-based relapse prevention treatments, in patients with bipolar depression previously responsive to ect and patients needing urgent treatment due to symptom severity during the covid-19 pandemic.

treatment resistant bipolar depression is a leading cause of disability and socioeconomic burden of disease, and current treatment options all suffer from critical deficiencies of efficacy, capacity, or tolerability, especially given the current covid-19 pandemic. rtms and alfr in particular has the potential to overcome many of these deficiencies, and is safe and well-tolerated. taken together with the reported findings of other groups, alfr may be feasible, tolerable, and capable of achieving comparable and potentially better remission rates than longer 20 to 30-day courses and it may also be beneficial to taper treatments and use symptom-based relapse prevention treatments in an alfr protocol. importantly, our pilot data in two patients previously responsive to ect and data from the cole et al. study suggest that accelerated rtms may be a potential substitute for ect as it may be possible to achieve remission in patients with severe depressive symptoms who would otherwise receive ect. furthermore, there is a burden of being able to provide care to as many people as possible based on severity of illness during the pandemic.
