Psychotropic Medication Use In Adolescents Research Articles

Prevalence and predictors of psychotropic medication use in adolescents and adults with autism spectrum disorder in Italy: A cross-sectional study

Autism spectrum disorder (ASD) is a group of life-long neurodevelopmental conditions with a prevalence of 1.5% in developed countries. Beside core symptomatology, ASD people are frequently affected by psychiatric comorbidities and behavioral problems. To date, only risperidone and aripiprazole have been approved for the pharmacological treatment of ASD-associated irritability in children and adolescents, while no guidelines exist for adults. The present cross-sectional study examined the prevalence and predictors of psychotropic medication use in 195 autistic subjects, aged between 14 and 58, treated in two Italian tertiary care centers. 58.5% of the sample were taking at least one medication; one third of the sample were on polypharmacotherapy. Antipsychotics were prescribed to 40% of the sample. Nearly 30% of the sample were on anticonvulsants/mood stabilizers. Both antidepressants and benzodiazepines were prescribed to approximately 16% of the subjects. IQ, epilepsy and psychiatric comorbidities were regarded as independent predictors of both mono- and polypharmacotherapy, while severity of repetitive behaviors predicted only polypharmacotherapy. Our data highlighted that medications prescribed to adolescents and adults with ASD are heterogeneous and often rely only on clinicians’ experience. Future research should investigate the effectiveness of psychotropic drugs in this specific population, to promote the development of appropriate treatment guidelines.

Psychotropic medication use in adolescents with intellectual disability living in the community

Information on the use of psychotropic medications in adolescents with intellectual disability is scant. Such information can guide interventions to improve psychotropic medication use in this population. We investigated the prevalence of, and factors associated with, psychotropic medication use in adolescents with intellectual disability in Australia who live in the community. Cross-sectional data were obtained from adolescents with intellectual disability living in the community in South East Queensland, Australia, between February 2007 and September 2010. Self-reported information on medication use was extracted from a health screening tool. Demographic and medical data were collected through parent/caregiver surveys. Medications were classified according to the Anatomical Therapeutic Chemical classification system. Psychopathology was assessed using the Developmental Behaviour Checklist Short Form. Logistic regression analysis was used to assess the association of demographic and medical characteristics with psychotropic medication use. There were 176 participants (median age = 16 years, range = 11-19 years; 55% male). Psychotropics were used by 20% of participants. Psychostimulants were the commonest psychotropic class, used by 9% of participants. Multipsychotropic prescribing was not common with only seven participants using more than one psychotropic agent. After adjusting for potentially confounding variables, use of psychotropic medications was significantly associated with male gender (adjusted odds ratio = 3.6; 95% confidence interval = 1.3-9.5) and having major behaviour problems (3.1; 1.1-8.9). Adolescents with intellectual disability use a wide range of psychotropic medications. Being male and having major behaviour problems are associated with the use of psychotropic medications. Research examining the rationale for psychotropic prescribing in this population is needed.

Prevalence and correlates of psychotropic medication use in adolescents with an autism spectrum disorder with and without caregiver-reported attention-deficit/hyperactivity disorder.

Many youths with an autism spectrum disorder (ASD) benefit from psychotropic medication treatment of co-morbid symptom patterns consistent with attention-deficit/hyperactivity disorder (ADHD). The lack of clear indications and algorithms to direct clinical practice has led to a very poor understanding of overall medication use for these youths. The present study examined the prevalence of psychotropic medication use compared across individuals with an ASD without a caregiver-reported ADHD diagnosis (ASD-only), ADHD without ASD (ADHD-only), and an ASD with co-morbid ADHD (ASD+ADHD). Correlates of medication use were also examined. Data on psychotropic medication from the first wave of the National Longitudinal Transition Study 2, a nationally representative study of adolescents ages 13-17 in special education, were used to compare the prevalence of medication use across the three groups, overall and by class. Separate logistic regression models were constructed for each group to examine the correlates of psychotropic medication use. Poisson regression models were used to examine correlates of the number of medications. Youths with ASD+ADHD had the highest rates of use (58.2%), followed by youths with ADHD-only (49.0%) and youths with ASD-only (34.3%). Youths with an ASD, both ASD-only and ASD+ADHD, used medications across a variety of medication classes, whereas stimulants were dominant among youths with ADHD-only. African American youths with ASD-only and with ASD+ADHD were less likely to receive medication than white youths, whereas race was not associated with medication use in the ADHD-only group. Clearer practice parameters for ADHD have likely contributed to more consistency in treatment, whereas treatment for ASD reflects a trial and error approach based on associated symptom patterns. Additional studies examining the treatment of core and associated ASD symptoms are needed to guide pharmacologic treatment of these youths. Interventions targeting African American youths with ASD and the physicians who serve them are also warranted.
