Declarations

Ethics approval and consent to participate: This case report was conducted in accordance with institutional ethical standards and the principles of the Declaration of Declaration of Helsinki. Formal ethics committee approval was waived due to the retrospective single-patient case report design and full anonymization of patient information.

Consent to publication: Written informed consent was obtained from the patient for publication of this case report and any accompanying images. A copy of the written consent is available for review by the Editor-in-Chief of this journal.

IRCT code: Not applicable to this study, as this report is not a clinical trial, involves no prospective intervention, and is based on retrospective reporting of routine clinical care.

Patient perspective: After recovery, the patient reported no clear recollection of the acute toxic phase or the period of unconsciousness during intensive care admission. During the early recovery period, she described experiencing severe headache, retro-orbital pain, and transient episodes of both anterograde and retrograde amnesia, all of which gradually resolved over the following days. Following neurological recovery, she acknowledged the intentional ingestion of caffeine tablets and expressed regret regarding the suicide attempt. At discharge, she reported significant physical improvement without persistent palpitations, chest discomfort, dyspnea, or neurological complaints. She and her family accepted referral for outpatient psychiatric and psychological follow-up, along with internal medicine and cardiology follow-up, with the goal of supporting long-term psychological recovery and preventing future self-harm.
