This study aimed to exhaustively assess attentional processes in psychotic adolescents and their relationships with clinical symptoms and diagnoses. A total of 24 adolescents hospitalized for a first episode of psychosis and their individually matched controls were assessed using theory-driven attentional tasks. No significant differences were found on sustained and selective attention tasks. Patients performed more poorly

than controls in a dual-task paradigm, suggesting a divided attention impairment. Significant deficits were also obtained on tasks requiring inhibition and flexibility capacities. No differences were found between schizophrenic and affective subgroups of patients. The intensity of the symptoms of psychosis did not seem to be associated with attentional performances. These findings suggest

that adolescents with a first episode of C59 wnt purchase psychosis show specific rather than global attentional impairments. Sustained and selective attention seems to be preserved, whereas divided attention and attentional control are impaired when compared to controls. The attentional profile seems to be unrelated to either the clinical symptomatology or the diagnosis underlying psychosis. A partial independence between cognition and clinical symptomatology could be hypothesized from these data but remains to be directly assessed in future studies. “
“Traumatic Dichloromethane dehalogenase brain injury (TBI) is a main cause of mortality and morbidity. Association studies between selleck chemicals llc hospitalization variables and cognitive impairment after TBI are frequently retrospective, including non-consecutive

patients showing variable degrees of TBI severity, and poor management of missing (drop out) cases. We assessed prospectively the demographic and hospitalization variables of 234 consecutive patients with severe TBI (admission Glasgow Coma Scale [GCS] ≤8) and determined their independent association with cognitive performance in a representative sample (n = 46) of surviving patients (n = 172) evaluated 3 (±1.8) years after hospitalization. In all, 85% of patients were male and the mean age was 34 (SD ±13) years. The education level was 9 (±4.7) years. As expected, education and age showed a moderately to strong linear relationship with the cognitive performance in 14 of 15 neuropsychological tests (R coefficient = 0.6–0.8). The cognitive test scores were not independently associated with gender, admission GCS, associated trauma, and Marshal CT classification. Admission-elevated blood glucose levels and the presence of sub-arachnoid haemorrhage were independently associated with lower scores on Rey Auditory Verbal Learning retention and Logical Memory-I tests, respectively.
