Anxiety symptoms in children are common, ranging from a toddler’s fear of the dark to an adolescent worrying about a major exam. The good news is that, if they are detected early and treated appropriately, they are curable. Unfortunately, they are often silent, or present with misleading symptoms. Screening for anxiety disorders, especially in the presence of the most common presenting concerns, can illuminate the true nature of a child’s challenge and point the way forward. In this month’s article, we will provide details on the prevalence of anxiety disorders in children, how they typically present, and how best to screen for them. We will offer some strategies for speaking about them with your patients and their parents, as well as introduce some of the strategies that can improve mild to moderate anxiety disorders. We will follow up with another piece on the evidence-based treatments for these common disorders, how to find appropriate referrals, and what you can do in your office to get treatment started.
Anxiety disorders: Common and treatable
Anxiety disorders – including separation anxiety disorder, social phobia, simple phobias, generalized anxiety disorder, panic disorder, and PTSD – affect between 15% and 20% of children before the age of 18, with some recent estimates as high as 31.9% of youth being affected. Indeed, the mean age of onset for most anxiety disorders (excluding panic disorder and PTSD) is between 5 and 9 years of age. Despite being so common, many anxiety disorders in childhood are never properly diagnosed, and most (as many as 80%) do not receive treatment from a mental health professional. With early diagnosis and evidence-based treatment, most anxiety disorders can be “cured” and no longer impair functioning. Untreated, anxiety disorders usually have a chronic course, causing significant behavioral problems and disruption of a child’s critical social, emotional, and identity development and their academic function. Untreated, they are frequently complicated in adolescence by mood, substance use, and eating disorders. With the passage of time, developmental consequences and comorbid illnesses, a curable childhood anxiety disorder can become a complex and entrenched psychiatric syndrome in young adulthood.

One of the reasons these illnesses frequently go unrecognized is that states of fearful distress, such as separation anxiety or social anxiety, are developmentally normal at different stages of childhood, and it can be difficult to discriminate between normal and pathological anxiety. Anxiety itself is an “internalizing” symptom, and is invisible except for the behaviors that can accompany it. Some behaviors suggest anxiety, such as fearful expressions, clinginess, excessive need for reassurance, or avoidance. But anxiety can also lead to obstinate refusal to do certain things. It might lead to explosive tantrums when a child is pushed to do something that makes them intensely anxious. It can lead to irritability and moody tantrums for a child exhausted after a long school day spent managing high levels of anxiety by themselves. Anxious children often appear inattentive in school. Anxiety disorders frequently disrupt restful sleep, leading to children who are irritable and moody as well as inattentive. These children may present to the pediatrician with frustrated parents concerned that they are oppositional or explosive, or because their teachers are concerned about ADHD, when the culprit is actually anxiety.
While anxiety is uncomfortable, these children are unlikely to experience their anxiety as unusual and foreign, like a sudden toothache. Instead, it feels to them like they are fearful for good reason, responding appropriately to something real. These children are more likely to respond to a novel or uncertain situation with worry rather than curiosity, and to a new challenge as a threat. For children who are managing their anxiety more internally, their parents are often unaware of their degree of distress. Indeed, these children are often careful, thoughtful, and attentive to detail. Parents and teachers may think they are doing wonderfully. They are typically very sensitive to physical discomforts, which are heightened by an anxious state. These are likely to present to the pediatrician’s office with parents very worried about a cluster of vague physical complaints (stomach ache, headache, “just not feeling good”), which coincides with a change, challenge, or anxious stimulus. In this situation, the parents may dismiss the possibility of anxiety, and the child may not even be aware of it. But it will get worse if they are pushed to bear the source of anxiety (going to school, sports practice, etc.).
