Is schizophrenia a brain disease or is it psychodynamic?

It is important to realize that schizophrenia may takeseveral forms and may have several causations. So it is increasingly common to think of “schizophrenias” rather than of “schizophrenia,” and to regard them as a syndrome or even collection of syndromes rather than as a unitary disorder. Extensive evidence exists and growing thatschizophrenia, orschizophrenias, are caused by brain abnormalities, most likely affecting brain development from very early on, years before the overt symptoms may become apparent
