Abstract
Background: In this case series, results from daily visual exposure to intense polychromatic light of 2000 to 4000 LUX is presented. Bright light treatment is a standard procedure for treating seasonal affective disorder and prodromal Parkinson's disease with high success. With the post-encephalitic symptoms of long-COVID closely approximating those of prodromal Parkinson's disease, we treated insomnia and sleep-related parameters in these patients, including total sleep, number of awakenings, tendency to fall back to sleep, and fatigue, to determine whether mending sleep could improve quality of life.
Case presentation: We present three female and two male Caucasian patients aged 42-70 years with long-COVID that persisted from 12 weeks to 139 weeks after contracting coronavirus disease.
Conclusion: A light presentation protocol was adapted for long-COVID that not only restored sleep in all patients, but also unexpectedly repaired the depression, anxiety, and cognitive changes (brain fog) as well. A robust pattern of recovery commencing 4-5 days after treatment and was maintained for weeks to months without relapse. These preliminary findings represent a novel, minimally invasive approach for managing the most debilitating symptoms of long-COVID, making it an ideal candidate for the drug hypersensitive, post-encephalitic brain. That a compromised circadian mechanism seen in Parkinson's disease may also underlie post-encephalitic long-COVID implicates a compromised role of the circadian system in these disorders.
期刊介绍：
JMCR is an open access, peer-reviewed online journal that will consider any original case report that expands the field of general medical knowledge. Reports should show one of the following: 1. Unreported or unusual side effects or adverse interactions involving medications 2. Unexpected or unusual presentations of a disease 3. New associations or variations in disease processes 4. Presentations, diagnoses and/or management of new and emerging diseases 5. An unexpected association between diseases or symptoms 6. An unexpected event in the course of observing or treating a patient 7. Findings that shed new light on the possible pathogenesis of a disease or an adverse effect
