Catatonia Chronicles: When the Lorazepam Challenge Shows a Delayed Response.

Background: Catatonia is a multifaceted disorder marked by diminished motor activity and communication, and often accompanied by heightened agitation and cognitive confusion. While historically associated with schizophrenia, recent revisions in the DSM-5 have broadened its connections to various mental and physical health disorders. The lorazepam challenge test (LCT) is used to diagnose and treat catatonia. This case challenges the traditional manifestation of catatonia and the timeline of the LCT. Case: The case discussed involves a young man whose primary manifestation was cognitive impairment, ultimately diagnosed as catatonia through a traditional 2 mg LCT. Although his initial response to the LCT was negative, a marked reduction of symptoms was observed hours later. Discussion: Timely diagnosis of catatonia led to symptom improvement and reduced hospitalization. This case challenges the conventional assessment timeline and highlights the need for further understanding of catatonia's pathophysiology and treatment response. It underscores the diagnostic challenges posed by catatonia's cognitive and ambiguous presentation. Conclusion: The response to lorazepam, its dosage, and timing remain enigmatic, accentuating the knowledge gap in catatonia research. Further investigations are required to unravel the intricacies of catatonia's manifestation, diagnosis, and treatment response.
