Chapter 19 Psychologic Treatment of Children and Adolescents
The provision of supportive counseling, anticipatory guidance, and parent psychoeducation (Chapter 5) combined with medication management of noncomplex attention-deficit/hyperactivity disorder (ADHD) and pervasive developmental disorders are commonly undertaken in the medical home. Youngsters with complex and co-occurring psychiatric illnesses require intervention from specially trained mental health clinicians.
19.1 Psychopharmacology
To ensure safe and appropriate use of psychotropic medications, prescribers should follow best practice principles that underlie medication prescribing (Table 19-1). The use of medication involves a series of interconnected steps including performing an assessment, deciding on treatment and a monitoring plan, obtaining treatment assent or consent, and implementing treatment. Cognitive, emotional, and/or behavior symptoms are targets for medication intervention when there is no response to available evidence-based psychosocial interventions, there is a significant risk of harm, and/or there is significant functional impairment. Commonly encountered target symptom domains include agitation, anxiety, depression, hyperactivity, inattention, impulsivity, mania, and psychosis (Table 19-2).

Stimulants
Stimulants are sympathomimetic drugs that act both in the central nervous system and peripherally by enhancing dopaminergic and noradrenergic transmission (Table 19-3). These medications are used to treat ADHD (Chapter 30) and in some cases as an adjunct in the treatment of depression and for fatigue or malaise associated with chronic physical illnesses. There is a range of stimulant options including those with short half-lives (typically 4 hr) and those with long half-lives (8-12 hr). The most commonly reported side effects are appetite suppression and sleep disturbances. Irritability, headaches, stomachaches, lethargy, hallucinations, and fatigue have also been reported. Anorexia and weight loss have been noted with controversy about their impact on ultimate growth in height.
Antidepressants
Antidepressant drugs act on pre- and postsynaptic receptors affecting the release and reuptake of brain neurotransmitters, including norepinephrine, serotonin, and dopamine (Table 19-4). These medications have been useful in the treatment of depressive, anxiety, and obsessive-compulsive disorders.
The selective serotonin reuptake inhibitors (SSRIs) are the first line of medication treatment for anxiety and depressive disorders; the evidence supports a higher degree of efficacy for anxiety compared to depression. They have a large margin of safety with no cardiovascular effects. Side effects include irritability, insomnia, appetite changes, gastrointestinal symptoms, headaches, diaphoresis, restlessness, and sexual dysfunction (Chapter 58). Withdrawal symptoms are more common in short-acting SSRIs. Behavioral activation and suicidal thoughts have been reported. This has led to recommendations for close monitoring for these adverse effects, especially in the 1st wks of treatment.
The tricyclic antidepressants (TCAs) have mixed mechanisms of action (e.g., clomipramine is primarily serotonergic; imipramine is both noradrenergic and serotoninergic). With the advent of the SSRIs, the lack of efficacy studies (particularly in depression), and more serious side effects, the use of TCAs in children has declined. They continue to be used in the treatment of some anxiety disorders (particularly obsessive-compulsive disorder) and, unlike the SSRIs, can be helpful in pain disorders. They have a narrow therapeutic index, with overdoses being potentially fatal (Chapter 58
