Introduction: Research on the impact of obstructive sleep apnea (OSA) on cognitive function has traditionally focused on the apnea-hypopnea-index (AHI) as the main predictor, disregarding other OSA components, such as sleep fragmentation and oxygen desaturation. This study takes a novel approach by investigating the best predictors for visuospatial...

Research on working memory (WM) in obstructive sleep apnea (OSA) is highly inconclusive and mainly based on short-term span and dual-task measures. This study aimed to assess the performance on a more complex and faster-paced WM task in individuals with and without OSA in the context of the individuals’ age, gender, and depression. 61 individuals (...

In the present study, we characterize a novel zebrafish mutant of solute carrier 18A2 ( slc18a2 ), also known as vesicular monoamine transporter 2 ( vmat2 ), that exhibits a behavioural phenotype partially consistent with human Parkinson´s disease. At six days-post-fertilization, behaviour was analysed and demonstrated that vmat2 homozygous mutant...

Background and Objective: Schizophrenia is a heterogeneous, severe psychiatric disorder with a poor life outcome, unsatisfactory treatment options, and poorly understood etiology. With its high heritability, genetic models are a suitable tool for studying this disorder. However, already available animal models do not cover the broad range of schizo...
