Opposed attentional hemi-bias on a visuoconstructive task in children with severe hyperactivity versus severe inattention

Epigenome Defines Aberrant Brain Laterality in Major Mental Illnesses

“…Note that, in this task (during which individuals are asked to detect the center of 10 or more horizontal lines on a paper), healthy individuals exhibit leftward attentional bias, as the right brain hemisphere is dominant for visuospatial attention [ 128 ]. However, patients with ADHD exhibit rightward attentional bias [ 129 ].…”

Asymmetry as a Common-Biological Law, Umsa and Psmu Physiology Chair Contribution in Asymmetry and Handedness Study

“…In part autism spectrum disorders were found to be accompanied by damaged structural hemispheric asymmetries in a brain areas broader range than others; right amygdale was found to be a participant in the pain reactions. The asymmetry role was depicted at Parkinson's disease, Alzheimer's disease, amyotrophic lateral sclerosis, multiple or disseminated sclerosis [28], dyslexia, depression, autism spectrum disorders (with rightward asymmetry and atypical hemispheric asymmetries for language and white matter microstructure reduced hemispheric asymmetry) [29,30], combined hyperactive/inattentive types (ADHD-C) with significant visual attentional bias to the right side and following left subclinical neglect in children and adult [31,32], anosognosia [33], schizophrenia (with digit ratio 2D:4D assessment), generalized anxiety disorder (with sympathetic and hypothalamic-pituitary-adrenal asymmetry on alpha-amylase and cortisol asymmetry while defining enzymes and hormones asymmetry id ОГЛЯДИ ЛІТЕРАТУРИ / LITERATURE REVIEWS est so-called biochemical one) [34], right and left benign mesial temporal lobe epilepsy (interhemispheric functional connectivity asymmetry damage) [35], post-traumatic stress disorders (amygdalar asymmetries) [36], social anxiety disorder (amygdala functional lateralization together with damaged fronto-amyglale communication with the pre-frontal cortex were found to be pathogenetically contributive), mild cognitive impairment while being determined in the asymmetry of choroid plexus, neurochemistry, protein distribution, brain connectivity and the vagus. There is a research comparing the data on hippocamp, amygdale and entorhinal cortex asymmetry in norm and at neurodegenerative disease [37].…”
