Cognitive disorders increase medication misuse risk. Early intoxication screening is vital for patients with hypothermia and coma, even without typical toxidrome signs.
Area of Science:
- Toxicology
- Emergency Medicine
- Geriatrics
Background:
- Cognitive disorders are linked to a higher risk of medication misuse and accidental self-poisoning.
- Accurate patient history, including cognitive status, is crucial for diagnosis.
Observation:
- A 68-year-old patient presented with hypothermia and coma due to accidental tricyclic antidepressant (TCA) intoxication.
- Notably, the patient lacked typical cardiac and hemodynamic abnormalities often associated with TCA overdose and hypothermia.
Findings:
- Intoxication should be suspected in patients with hypothermia and altered consciousness, alongside neurological or metabolic conditions.
- The absence of a classic toxidrome does not rule out poisoning.
Implications:
- Early screening for intoxication is recommended for patients with cognitive disorders presenting with coma and hypothermia.
- This case highlights the importance of considering poisoning in undifferentiated presentations of hypothermia and altered mental status.

Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
