Child and adolescent psychiatry or pediatric psychiatry is a branch of psychiatry that focuses on the diagnosis, treatment, and prevention of mental disorders in children, adolescents, and their families. It investigates the biopsychosocial factors that influence the development and course of these psychiatric disorders and treatment responses to various interventions.
When psychiatrists and pediatricians first began to recognize and discuss childhood psychiatric disorders in the 19th century, they were largely influenced by literary works of the Victorian era. Authors like the Brontë sisters, George Eliot, and Charles Dickens, introduced new ways of thinking about the child mind and the potential influence early childhood experiences could have on child development and the subsequent adult mind. When the Journal of Psychological Medicine and Mental Pathology, the first psychiatric journal in English, was published in 1848, child psychiatry didn’t exist as its own field yet. However, some of the earliest works on the possibility of nervous disorders and "insanity" in children were published in the Journal and several medical writers directly referenced works such as Jane Eyre (1847), Wuthering Heights (1847), Dombey and Son (1848), and David Copperfield (1850), to illustrate this new conceptualization of the child mind. Until that time, it was generally accepted that children were free from nervous disorders and the "passions" that affected the adult mind.
As early as 1899, the term "child psychiatry" (in French) was used as a subtitle in Manheimer's monograph Les Troubles Mentaux de l'Enfance. However, the Swiss psychiatrist Moritz Tramer (1882–1963) was probably the first to define the parameters of child psychiatry in terms of diagnosis, treatment, and prognosis within the discipline of medicine, in 1933. In 1934, Tramer founded the Zeitschrift für Kinderpsychiatrie (Journal of Child Psychiatry), which later became Acta Paedopsychiatria. The first academic child psychiatry department in the world was founded in 1930 by Leo Kanner (1894–1981), an Austrian émigré and medical graduate of the University of Berlin, under the direction of Adolf Meyer at the Johns Hopkins Hospital, Baltimore. Kanner was the first physician to be identified as a child psychiatrist in the US and his textbook, Child Psychiatry (1935), is credited with introducing both the specialty and the term to the Anglo-phone academic community. In 1936, Kanner established the first formal elective course in child psychiatry at the Johns Hopkins Hospital. In 1944 he provided the first clinical description of early infantile autism, otherwise known as Kanner's Syndrome.
