Some authors observed episodic memory impairments in all the patients with schizophrenia. Others sustained that distinct episodic memory profiles could differentially be expressed across clinical subtypes (Brazo et al. 2002).

Aim:

We wanted to investigate whether the different processes of episodic memory (encoding, storage and retrieval) were impaired differently from one clinical subtype of schizophrenia to another.

Methods:

Sixty-one schizophrenic patients (DSMIV) were categorized into independent subtypes with the Positive and Negative Syndrome Scale and the Schedule for the Deficit Syndrome as follows : deficit (N=12), disorganized (N=9), positive (N=19) and residual (N=21) subtypes. Sixty-one healthy controls were matched on age, sex and educational level. Episodic memory was explored through the California Verbal Learning Test (CVLT) using all the clues.

Results:

Three episodic memory profiles were identified in patients compared to controls : one was characterized by impaired encoding, the second by both impaired encoding and retrieval, the third by no significant impairment. Moreover, these profiles were distributed across all the clinical subtypes and none of them characterized a subtype in particular.
