Subjective perception of cognitive deficit in psychotic patients.
The objective of this study is to evaluate the subjective perception of cognitive deficit and how it relates to the perception of patients' relatives. Differences between the subjective perception of cognitive deficits in 107 DSM-IV-diagnosed psychotic patients and that of their relatives or caregivers were evaluated using the GEOPTE Scale. Fair agreement was observed between patient and family perception of cognitive functions, although there were important differences on those items that correspond to social functioning. A high degree of correlation was detected between the scores on this scale and clinical global impression scores, as well as the physicians' global impression of cognitive impairment. Psychotic patients maintain insight as to their cognitive deficits, but they fail to conserve an awareness of their perception of social functioning.

Association between FOXP2 polymorphisms and schizophrenia with auditory hallucinations.
OBJECTIVE: A mutation in the FOXP2 gene has been the first genetic association with a language disorder. Language disorder is considered as a core symptom of schizophrenia. Therefore, the FOXP2 gene could be considered a good candidate gene for the vulnerability to schizophrenia. METHODS: A set of single nucleotide polymorphisms mainly located in the 5' regulatory region of the FOXP2 gene was analysed in a sample of 186 DSM-IV schizophrenic patients with auditory hallucinations and in 160 healthy controls. RESULTS: Statistically significant differences in the genotype (P=0.007) and allele frequencies (P=0.0027) between schizophrenic patients with auditory hallucinations and controls were found in the single nucleotide polymorphism rs2396753. These P values changed to 0.07 and 0.0273, respectively, after Bonferroni sequential correction. The haplotype rs7803667T/rs10447760C/rs923875A/rs1358278A/rs2396753A (TCAAA) also showed a significant difference confirmed with a permutation test (P=0.009). CONCLUSIONS: These results suggested that the FOXP2 gene may confer vulnerability to schizophrenic patients with auditory hallucinations.
