Serial neuropsychological assessment of an adolescent girl after suffering a sudden out-of-hospital-cardiac-arrest following recreational inhalant use.

Sudden out-of-hospital-cardiac-arrest (OHCA) following recreational inhalant use is well documented in the literature. The present case study reports the long-term neuropsychological sequelae of a 14-year-old girl who suffered an OHCA secondary to recreational butane gas inhalation. The patient was assessed on day-13 as an inpatient, and again at 3- and 12-month outpatient follow-ups. Acutely the patient demonstrated significant impairment on tasks associated with verbal and non-verbal memory and executive functioning. Re-testing at 3-months post-acute state suggested improved executive and non-verbal functions while showing continued deficits in verbal memory. At 12-months she was cognitively performing at levels expected for her age. This case is reported for its rarity in successfully being able to track the patient's clinical course from hospital discharge to the successful reintegration back into school and community settings.
