They may include motor and cognitive dysfunction, speech and hearing impairments, behavioural problems and psychopathology such as anxiety, delusions and hallucinations.

Behavioural disturbances and psychopathology
What are antecedents? Antecedents such as behavioural disturbances and psychopathology are subtle deviations in development that may become evident during childhood or adolescence. The presence of these deviations may foreshadow the later development of schizophrenia, however most children who exhibit these antecedents do not develop the disorder. Studies exploring antecedents are ideally based on representative, population-based samples that follow the group from birth through childhood and adolescence to adulthood. These studies can provide unique insights into the changes in developmental trajectories that may be associated with schizophrenia. What is the evidence for behavioural disturbances and psychopathology? Overall, moderate quality evidence…

Studies exploring antecedents are ideally based on representative, population-based samples that follow the group from birth through childhood and adolescence to adulthood. These studies can provide unique insights into the changes in developmental trajectories that may be associated with schizophrenia.
