Schizophrenia is characterized by disturbances
in perception, thought, emotion, affect, and social relatedness.
Early-onset schizophrenia (EOS) is defined as onset prior to age
18 years, with childhood-onset schizophrenia (COS) referring to
onset before age 13 years. EOS is considered to be continuous with
adult-onset schizophrenia yet manifests with special developmental
and social challenges. This chapter will provide information on
history, etiology, neurobiological and genetic characteristics,
clinical presentation, and an overview of psychosocial and pharmacological
interventions to provide a basis for comprehensive care of children
and adolescents with schizophrenia and related disorders.
