Naturalistic studies establishing, the base rates of eventual illness are, therefore, critical, for evaluating the successfulness of early treatment. Since there is an absence of established diagnostic criteria, the significance of validity of these scales is doubted. The critical period of intervention when identified clarifies the doubts about faster and better outcomes. Although PRS has potential predictive ability, because of its current “insufficient” discriminative power at the individual level for clinical use, it remains limited solely in the research area, specifically in the psychiatric field.

Understanding the prodrome phase is fundamentally changing researchers’ view of what is happening at the very earliest phases of a migraine attack, which then leads to different treatment targets. The whole picture of this prodromal, phase should also be compared to the DSM-IV concepts, of fully psychotic disorders that have not been present, for long enough to meet the criteria for schizophrenia, or schizoaffective disorder. The patients, materialized improvement in positive, negative and general, symptoms with betterment in functioning in comparison to, study of the effect of psychosocial modification on the, vulnerable individuals helps the young person to regain their, capacity for psychological well-being and improved quality, of life.
