Lessons on catatonia with or without delirium on the consultation-liaison psychiatry service in a Lebanese tertiary care center: a retrospective chart review of 36 cases of catatonia

The study highlights the overlap between delirium and catatonia. Based on existing literature, we propose a model that conceptualizes catatonia and delirium as maladaptive sickness responses related to neuroinflammation and the defense cascade. This model has the potential to explain the shared pathophysiology of the two syndromes, offering a framework for future investigations.
