ABSTRACT
BACKGROUND: Emerging literature supports the association between acute COVID-19 infection and neuropsychiatric complications. This article reviews the evidence for catatonia as a potential neuropsychiatric sequela of COVID-19 infection. METHODS: PubMed was searched using the terms catatonia, severe acute respiratory syndrome coronavirus 2, and COVID-19. Articles were limited to those published in the English language between 2020 and 2022. Forty-five articles that specifically studied catatonia associated with acute COVID-19 infection were screened. RESULTS: Overall, 30% of patients with severe COVID-19 infection developed psychiatric symptoms. We found 41 cases of COVID-19 and catatonia, with clinical presentations that varied in onset, duration, and severity. One death was reported in a case of catatonia. Cases were reported in patients with and without a known psychiatric history. Lorazepam was successfully used, along with electroconvulsive therapy, antipsychotics, and other treatments. CONCLUSIONS: Greater recognition and treatment of catatonia in individuals with COVID-19 infection is warranted. Clinicians should be familiar with recognizing catatonia as a potential outcome of COVID-19 infection. Early detection and appropriate treatment are likely to lead to better outcomes.

Huntington's disease (HD) is a rare neurodegenerative disease of the central nervous system characterized by choreatic movements, behavioral disturbances, and neuropsychiatric sequelae. The disease is inherited in an autosomal dominant fashion by an increased number of CAG repeats on the short arm of chromosome 4p16.3 in the Huntingtin gene. Huntington's disease demonstrates the genetic principle of anticipation, where the larger the number of CAG repeats the earlier the signs and symptoms of the disease appear in subsequent generations. The symptoms often consist of behavioral disturbances and learning disturbances. The disease is suspected based on signs and symptoms and confirmed by genetic testing. There is no cure for the disease, and there is a high rate of neuropsychiatric symptoms including depression, and aggressive behavior. A significant risk of suicide in this population exists given the severity and unrelenting nature of the disease. Most patients will have multiple hospitalizations during the course of the illness. A consultant psychiatrist may be asked to evaluate and make recommendations for the treatment of acute agitation in HD patients. This can be a challenging task given the limited number of studies and the complex nature of agitation in the hospital setting. The aim of this review is to look at the currently available data for the treatment of acute agitation in patients with Huntington's disease.
