This month we are following up on our previous piece on anxiety disorders. We wrote about how these disorders are common, amenable to treatment, and often curable, but are often missed as many children suffer silently or their symptoms are mistaken for signs of other problems. We reviewed the screening instruments that can help you to catch these “quiet” illnesses. Now, we are going to offer some detail about the effective treatments for the most common anxiety disorders and how to approach getting treatment started when a screen has turned up positive. If you are interested in a deeper dive, the American Academy of Child and Adolescent Psychiatry has detailed practice parameters for the disorders discussed below.
Anxiety disorders in young children
Dr. Susan D. Swick
Separation anxiety disorder, specific phobia, generalized anxiety disorder, and social phobia are the anxiety disorders that most commonly affect the youngest children. Separation anxiety disorder is the most common childhood anxiety disorder and has an average age of onset of 6 years, whereas specific phobia peaks between 5 and 8 years of age, generalized anxiety disorder peaks at 8 years old and social phobia (or social anxiety disorder) has a peak age of onset of 13 years. The first-line treatment for each disorder is cognitive-behavioral therapy (CBT), and specifically a variant called exposure and response prevention. This treatment essentially helps patients to “learn” to have a different response, not anxiety, to the triggering thought or stimulus. CBT can be very effective, curative even, but these disorders can be difficult to treat when a child’s level of anxiety exceeds their ability to engage in treatment. In these cases, treatment can be facilitated by the addition of an SSRI, which is recommended by the American Academy of Child and Adolescent Psychiatry as a second-line treatment in children aged 6-18 years. Given the anxious child’s sensitivity to some side effects (such as GI distress) starting at a low dose and titrating up slowly is the recommendation, and effective dose ranges are higher than for the treatment of mood disorders. Without treatment, these disorders may become learned over years and predict complicating anxiety, mood, and substance use disorders in adolescence and adulthood. Any treatment can be helped by the addition of parent guidance, in which parents learn how to be emotionally supportive to their anxious children without accommodating to their demands or asking them to avoid of the source of anxiety.
Obsessive-compulsive disorder
Mild obsessive-compulsive disorder (OCD) describes what many of us do, like double-checking we have locked our door or put our work into our briefcase. OCD as a diagnosis with substantial dysfunction has a peak onset at age 10 and again at the age of 21. Over 50% of childhood-onset OCD will have a comorbid anxiety, attention, eating, or tic disorder. Without treatment, OCD is likely to become chronic, and the symptoms (intrusive thoughts, obsessive rumination, and compulsive behaviors) interfere with social and academic function. The behavioral accommodations and avoidance of distress that mark untreated OCD interfere with the healthy development of normal stress management skills that are a critical part of early and later adolescence. First-line treatment is CBT (with exposure and response prevention) with a therapist experienced in the treatment of OCD. A detailed symptom inventory (the Children’s Yale-Brown Obsessive Compulsive Scale) is relatively simple to complete, will confirm a suspected OCD diagnosis, and will create a valuable baseline by which treatment efficacy can be assessed. For those children with moderate to severe OCD, addition of an SSRI to augment and facilitate CBT therapy is recommended. Sertraline, fluvoxamine, fluoxetine, and paroxetine have all been studied and demonstrated efficacy. Clomipramine has well-established efficacy, but its more serious side effects and poorer tolerability make SSRIs the first choice. As with other anxiety disorders, starting at very low doses and titrating upward gradually is recommended. The efficacy of medication treatments is lower in those patients who have other psychiatric illnesses occurring with OCD. Again, parent guidance can be invaluable in supporting the child and improving family well-being.
