Aim: To examine the relationship between cognitive deterioration and the duration of untreated psychosis (DUP) in a first-episode psychosis sample.
Method: We assessed a consecutive sample of first-episode psychosis participants (N = 50) with measures of cognitive deterioration and DUP.
Results: Using correlations and stepwise linear regressions, we found strong relationships between DUP and measures of cognitive deterioration.
Conclusions: The length of DUP predicted cognitive deterioration. These results highlight a potential DUP grace period (>6 months) in which significant cognitive deterioration may be averted.
