An epidemiological study of the use of ECT in adolescents.
OBJECTIVE
There is little knowledge about the use of electroconvulsive therapy (ECT) in adolescents. Given the prevalence and severity of psychiatric disorders in this age group, it is important to determine the frequency, indications, effectiveness, and side effects of ECT.


METHODS
Persons younger than 19 years who received ECT between 1990 and 1996 in the Australian state of New South Wales were identified. Detailed information about diagnosis, treatment, and outcome was then obtained.


RESULTS
Forty-two patients aged 14 to 18 years underwent a total of 49 courses comprising 450 ECTs (0.93% of all treatments given to all persons). Marked improvement or resolution of symptoms occurred in half of the completed courses. Mood disorders derived most benefit from ECT. Side effects were transient and minor. Prolonged seizures were observed in 0.4% of treatments. Comorbid personality disorder predicted poorer response, and the anesthetic propofol was associated with shorter seizures.


CONCLUSIONS
Although ECT is an effective treatment for some mental disorders in adolescents and has few side effects, it is seldom used. Indications, response, and unwanted effects were similar to those observed in adults. The use of propofol may reduce the risk of prolonged seizures.
