Alertness and visuospatial attention in clinical depression

چکیده
BACKGROUND Cognitive deficits are a substantial burden in clinical depression. The present study considered dysfunction in the right-hemispheric attention network in depression, examining alertness and visuospatial attention. METHODS Three computerized visuospatial attention tests and an alertness test were administered to 16 depressive patients and 16 matched healthy controls. RESULTS Although no significant group effect was observed, alertness predicted reduced visuospatial performance in the left hemifield. Furthermore, sad mood showed a trend towards predicting left visual field omissions. CONCLUSIONS Decreased alertness may lead to lower left hemifield visuospatial attention; this mechanism may be responsible for a spatial bias to the right side in depression, even though treatment of depression and anxiety may reduce this cognitive deficit.

1) I am not sure if the trendlevel result for the influence of sad mood on one of the three visuospatial tests is justification enough for the conclusion: “...alertness and – to a lesser extend – sad mood led to left omissions in visuospatial neglect tests”. The manuscript has been changed accordingly (p.2, ll.10-12). Background: 2) In the literature, the term “unilateral neglect” seems to be c...
متن کاملLow arousal modulates visuospatial attention in three-dimensional virtual space.
Clinical, experimental, and functional imaging studies suggest overlapping neuronal networks and functional interactions of alertness and visuospatial attention within the right hemisphere of the brain. To examine the interaction of arousal and visuospatial attention in peripersonal and extrapersonal virtual space, we tested 20 healthy male adults during 24 hr of sleep deprivation at four point...

There is strong evidence that depression is associated with neuropsychological deficits across multiple domains. However, research on this topic has spanned a variety of measures with different psychometric properties and normative samples, which prevents drawing definitive conclusions about the pattern of neuropsychological deficiencies. The Repeatable Battery for the Assessment of Neuropsycho...

OBJECTIVE The goal was to determine whether breakfast had effects on the cognitive performance and mood of high school students. METHODS A crossover trial was performed in boarding schools, involving 104 students between 13 and 20 years of age. The participants were randomly assigned to 2 equal-size groups on the morning of the first testing day. One half of the total sample received a standa...
