Preliminary investigation of lithium for mood disorder symptoms in children and adolescents with autism spectrum disorder.

OBJECTIVE: Children with autism spectrum disorder (ASD) have higher rates of comorbid psychiatric disorders, including mood disorders, than the general child population. Although children with ASD may experience irritability (aggression, self-injury, and tantrums), a portion also experience symptoms that are typical of a mood disorder, such as euphoria/elevated mood, mania, hypersexuality, paranoia, or decreased need for sleep. Despite lithium's established efficacy in controlling mood disorder symptoms in the neurotypical population, lithium has been rarely studied in children with ASD. METHODS: We performed a retrospective chart review of 30 children and adolescents diagnosed with ASD by the Diagnostic and Statistical Manual of Mental Disorders, 4th ed., Text Revision (DSM-IV-TR) criteria who were prescribed lithium in order to assess target symptoms, safety, and tolerability. Clinical Global Impressions - Improvement (CGI-I) ratings were performed by two board-certified child psychiatrists with expertise in ASD. CGI-I scores were dichotomized into "improved" (CGI-I score of 1 or 2) or "not improved" (CGI-I score ≥3). RESULTS: Forty-three percent of patients who received lithium were rated as "improved" on the CGI-I. Seventy-one percent of patients who had two or more pretreatment mood disorder symptoms were rated as "improved." The presence of mania (p=0.033) or euphoria/elevated mood (p=0.041) were the pretreatment symptoms significantly associated with an "improved" rating. The mean lithium blood level was 0.70 mEq/L (SD=0.26), and the average length of lithium treatment was 29.7 days (SD=23.9). Forty-seven percent of patients were reported to have at least one side effect, most commonly vomiting (13%), tremor (10%), fatigue (10%), irritability (7%), and enuresis (7%). CONCLUSIONS: This preliminary assessment of lithium in children and adolescents with ASD suggests that lithium may be a medication of interest for those who exhibit two or more mood disorder symptoms, particularly mania or euphoria/elevated mood. A relatively high side effect rate merits caution, and these results are limited by the retrospective, uncontrolled study design. Future study of lithium in a prospective trial with treatment-sensitive outcome measures may be indicated.

Family-focused treatment for adolescents with bipolar disorder: results of a 2-year randomized trial.

CONTEXT: Family interventions have been found to hasten episode recovery and delay recurrences among adults with bipolar disorder. OBJECTIVE: To examine the benefits of family-focused treatment for adolescents (FFT-A) and pharmacotherapy in the 2-year course of adolescent bipolar disorder. DESIGN: Two-site outpatient randomized controlled trial with 2-year follow-up. PATIENTS: A referred sample of 58 adolescents (mean [SD] age, 14.5 [1.6] years) with bipolar I (n = 38), II (n = 6), or not otherwise specified disorder (n = 14) with a mood episode in the prior 3 months. INTERVENTIONS: Patients were randomly assigned to FFT-A and protocol pharmacotherapy (n = 30) or enhanced care (EC) and protocol pharmacotherapy (n = 28). The FFT-A consisted of 21 sessions in 9 months of psychoeducation, communication training, and problem-solving skills training. The EC consisted of 3 family sessions focused on relapse prevention. MAIN OUTCOME MEASURES: Independent "blind" evaluators assessed patients every 3 to 6 months for 2 years. Outcomes included time to recovery from the index episode, time to recurrence, weeks in episode or remission, and mood symptom severity scores. RESULTS: Analyses were by intent to treat. Rates of 2-year study completion did not differ across the FFT-A (60.0%) and EC conditions (64.3%). Although there were no group differences in rates of recovery from the index episode, patients in FFT-A recovered from their baseline depressive symptoms faster than patients in EC (hazard ratio, 1.85; 95% confidence interval, 1.04-3.29; P = .04). The groups did not differ in time to recurrence of depression or mania, but patients in FFT-A spent fewer weeks in depressive episodes and had a more favorable trajectory of depression symptoms for 2 years. CONCLUSIONS: Family-focused therapy is effective in combination with pharmacotherapy in stabilizing bipolar depressive symptoms among adolescents. To establish full recovery, FFT-A may need to be supplemented with systematic care interventions effective for mania symptoms.
