Prodromes de la schizophrénie : consensus ou confusion ?

This suggests that the population of subjects with prodromes is structured by two latent subgroups: those who express transient psychotic manifestations (which are quite frequent in the general population), and those with an active psychotic process, who are progressively evolving towards the categorical diagnostic of schizophrenia. However, results obtained by between groups comparison of mean psychometric variables are unable to distinguish between these two populations at baseline. Because of this, introduction of the risk of psychosis category in the DSM-V has been bitterly criticized. In accordance, therapeutic prevention assays using antipsychotics, antidepressants, or cognitive therapy have provided inconsistent results. Only the administration of ω-3 polyunsaturated fatty acids has produced a long term efficient effect.
