Chapter 27. Features of Mental Disorders in Childhood and Adolescence

4 topics with concise reviews: definitions, key facts, and class questions.

Child psychiatry is not simply "adult psychiatry in miniature." A child's brain is actively developing, so the boundaries between normal and pathological are finer here, and the clinical presentation changes depending on age. In this chapter, we examine conditions that manifest specifically in the first years of life and during puberty.

The section includes four key topics: autism spectrum disorders (ASD), attention deficit hyperactivity disorder (ADHD), tic disorders, and behavioral disorders. You will learn how to distinguish ordinary educational neglect or the features of an age-related crisis from a real psychiatric diagnosis.

During practical classes and tests, you will certainly be asked about the diagnostic triad of ASD, the criteria for diagnosing ADHD, and the differential diagnosis of transient tics versus Tourette syndrome. Also, be prepared to answer questions on the tactics of communicating with a patient's parents—in pediatric practice, treatment is impossible without their compliance.

Frequently asked questions for this section

How to distinguish myoclonic epileptic seizures from tics in a child?

Unlike tics, which a child can temporarily restrain by a volitional effort, myoclonic seizures in epilepsy are completely uncontrolled and accompanied by complete amnesia — children simply do not notice them.

What is the difference between delusional and non-delusional dysmorphophobia?

In the non-delusional form, the patient retains critical insight and the ability to communicate with the doctor. The delusional form is characterized by complete, unshakable conviction in the defect, secrecy, suicide risk, and often points to schizophrenia.

Why is it necessary to rule out epilepsy when tics are suspected?

Minor and myoclonic seizures outwardly resemble muscle twitching, which is why parents and teachers often mistakenly take them for tics or fooling around.

How often do mental pathologies occur in children compared to adults?

Contrary to popular myth, mental disorders in minors occur with the same frequency as in the adult population.
