Why treating early, treating well, and treating for life is important in schizophrenia

Schizophrenia is a progressive illness, with many psychotic episodes. Brain imaging studies have consistently demonstrated brain abnormalities in patients with schizophrenia. These changes are largely confined to decreases in gray matter volumes and enlargement of the lateral and third ventricles. To date schizophrenia has been considered to result from abnormalities in neurodevelopment, with brain changes to be static. However, schizophrenia has long been thought to be a progressive or a degenerative, not a developmental, disorder. Indeed, Kraepelin considered the progressive clinical deterioration to be the hallmark of the disorder, naming it dementia praecox to reflect this particular aspect. Lately, others have re-emphasized the importance of the decline in functioning in schizophrenia as a clue to its pathogenesis, suggesting that the brain abnormalities in schizophrenia could be expected to reflect this clinical progression. Indeed, we and others have reported brain abnormalities to increase over time in schizophrenia. Interestingly, not all patients show changes in brain volumes over time: we demonstrated that the changes are particularly pronounced in those patients with a poor prognosis in the first years of illness. Moreover progressive changes are most pronounced in the frontal and temporal areas as postulated by Kraepelin over a hundred years ago. Interestingly, white matter did not change over time. Also we found that brain loss over time was most pronounced in patients who had been psychotic longest. Finally, the progression in these frontal brain changes appeared to be attenuated by treatment with atypical, but not by typical antipsychotics. Thus, not only are brain changes progressive in schizophrenia, they are clinically relevant since they are related to outcome and may be reversed by some of the atypical antipsychotics. With the evidence pointing to a link between progressive disease and patient outcomes, it is becoming increasingly clear that every effort should be made to prevent psychotic relapses. Using medications with maximal effect is therefore warranted.
