ABSTRACT

OBJECTIVES: To evaluate the usability of a neuropsychological screening instrument and two observation scales of everyday behaviour to describe cognitive and functional capacity of patients with multiepisode schizophrenia and considerable care needs, who frequently refuse to participate in cognitive testing or performance-based functional measurement. SETTING: One psychiatric unit specialised in severe mental illness at the Sahlgrenska University Hospital, Gothenburg, Sweden. PARTICIPANTS: Patients were included consecutively from date of admission to the unit. INCLUSION CRITERIA: age 18-65 years, International Classification of Diseases 10 diagnoses F20.0-F20.9 (schizophrenia) or F25.0-F25.9 (schizoaffective disorder) since at least 5 years. EXCLUSION CRITERIA: acute serious psychotic episodes or physical illness, alcohol or drug abuse during the year before the study, diagnosed cerebral disorder at admission to the unit, and insufficient ability to speak Swedish. 64 patients filled the criteria and 19 accepted participation: 14 males, 5 females, median age 56 years. OUTCOME MEASURES: Barrow Neurological Institute Screen for Higher Cerebral Functions (BNIS) scores, measured by a psychologist; Frontal Systems Behaviour Scale (FrSBe) Family Version and Functional Independence Measure (FIM) V.4.0 scores, measured by nursing staff. Non-parametric statistics were consistently applied to process the data. RESULTS: Failure analysis showed differences regarding gender and subdiagnoses between participants and non-participants. All participants had BNIS scores indicating cognitive dysfunction. FrSBe group medians showed apathy and executive problems, indicating possible frontal lobe disturbance. FIM showed dependency on others for linguistic and social communication, everyday problem solving, and remembering persons and daily routines. Correlations between FrSBe and FIM (p≤0.01) suggested executive dysfunction being crucial to explain difficulties in performing activities of daily functioning. CONCLUSIONS: Indications of considerable cognitive and functional difficulties found among the participants suggestedthat the instruments are clinically applicable for tentative assessment of cognitive and functional ability among patients with multiepisode schizophrenia and considerable care needs.

ABSTRACT

Obstructive sleep apnea syndrome (OSAS) is characterized by snoring and apnea during sleep leading to decreased oxygen saturation and disturbed sleep, excessive daytime sleepiness and neuropsychological disturbances. This study investigates cognitive neuropsychological abilities in a group of 53 OSAS patients before and after treatment with uvulopalatopharyngoplasty. General intellectual ability, verbal learning and memory as well as executive functioning were measured at baseline and 6 months postoperatively. After surgery there were significant improvements in verbal learning and memory (mean change -39, SD 57.3, p < 0.001), recall (mean change -24.3, SD 39.3, p < 0.001) and executive functioning (as assessed by percentage of errors on the Wisconsin Card Sorting Test; mean change -9.1, SD 15.7, p < 0.001). These improvements were in accordance with improvements in the degree of sleep apnea, the oxygen desaturation index (mean change -9.7, SD 15.9, p < 0.001) and arterial minimum oxygen saturation (mean change 4.5%, SD 10.2%, p < 0.01). Surgical treatment seems to improve verbal learning, memory and recall and executive functions in parallel with better oxygenation in OSAS.
