“…The following methods and inclusion and exclusion criteria were adapted from Rysstad and Pedersen ( 2016 ), who conducted a meta-analysis on non-right handedness among individuals within ASD. Computerized searches were conducted in PubMed, PsycInfo and CINAHL databases with the purpose of identifying all relevant articles published in English, without imposing limits on the time interval.…”

“…Based on the results of the description-based searches, citation-based searches were conducted using Google Scholar. This strategy had previously proven to be much more effective in identifying relevant papers, compared with more traditional searches (see Rysstad and Pedersen, 2016 for details). Google Scholar includes articles from every other database and reports the citations for each article.…”

“…Handedness found in other comorbid diagnoses may give an indication of what to expect in DCD. In a review of 12 studies including a total of 497 individuals diagnosed with ASD, Rysstad and Pedersen ( 2016 ) found 16% left-handers and 44% mixed-handers, giving a total of 60% non-right-handers. Furthermore, in a meta-analysis of dyslexia, Eglinton and Annett ( 1994 ) reported a significant difference in handedness distribution between dyslectics and control groups.…”

The Prevalence of Left-Handedness Is Higher Among Individuals With Developmental Coordination Disorder Than in the General Population

Many medical, psychiatric and neurological conditions have been characterized by a high prevalence of left-handedness or mixed-handedness. Several studies have indicated an elevated frequency of left-handedness in children with Developmental Coordination Disorder (DCD). However, there have been few studies explicitly exploring this relationship. The assumption is that the prevalence of left-handedness in individuals with DCD is higher compared with the prevalence in the general population and resembles the prevalence described in children with other developmental disorders. Computerized searches were conducted in PubMed, PsycInfo and CINAHL databases. Thirty-eight studies were identified and included in the present review, containing handedness distributions across 1071 persons with DCD and 1,045 controls. The distribution of DCD participants across handedness-categories was proved to be significantly different from that of the control group, with 14.7 and 8.1% left-handers, respectively. The prevalence of left-handedness within the DCD-group is lower than that reported for ASD, and larger than in dyslexia. The elevated levels of left-handedness within the different developmental disorders supports the notion of an association between the different diagnoses. However, the present results are not sufficient to conclude anything about a common cause or underlying factor via the male hormone testosterone. The present results could act as a starting point for testing the hypothesis of such a common factor, as one of the requirements is an elevated prevalence of left-handedness, and without such considerable doubt would be cast upon the hypothesis.

“…In fact, language and hand dominance have been found to be correlated (Knecht et al, ). Also, facial and eye movements in children are evidently related to hemispheric specialization and handedness (Arteaga & Poblano, ), as well as uncommon brain laterality functions results correlated to pathological aspects (Johnston, Nicholls, Shah, & Shields, , Rysstad & Pedersen, ). Finally, a relation between gustatory brain activations and hand dominance has also been observed (Faurion et al, ) and we can suppose that in cases where this factor was neglected, the clinical evidence cannot be generalized to build a model.…”

The focus of this review is to interpret recent advances in human gustatory pathways with respect to the laterality of gustatory responses. Psychophysical, neuroimaging, and clinical anatomical studies published in peer reviewed scientific journals were examined. From the anatomical and neuroimaging studies a total of six models are outlined and discussed in the light of some recent psychophysical and clinical results. In the specific of the salt condition and right preferred hand the outcomes have revealed a predominant left ipsilateral pathway with evidences of ipsilateral projection from the left primary gustatory cortex (PGC) to the orbitofrontal cortex, while a bilateral projection from the right oral cavity to the left and right insula seems to be more consistent. Also, the right side predominance of the chemosensory perception is objected. Additionally, the gustatory response appears to be dependent on the taste quality, supporting the idea of a chemotopical organization of the PGC as well as the Labelled-Line Model theory of peripheral taste quality encoding. However, where the fibers branch along the ascending pathway is not unequivocally established. Interestingly, factors like handedness appear to be remarkable when studying the lateralization of brain functions. Finally we suggest that further studies must include handedness and taste quality as distinctive factors that can help to interpret the results in a unique way.

“…As an example, individuals suffering minor prenatal brain insults show a shift toward right-hemisphere dominance, leading more likely to left-handedness 35 . Also, left-handed are reported to more likely suffer from depressive symptoms 36 and individuals diagnosed with autism spectrum disorder are significantly more left-handed than right-handed 37 , 38 . This implies that an association between left- (or mixed) handedness and variables representing birth development and complications is plausible.…”

The origin of human handedness and its role in pre-birth motor control

The vast majority of humans are right-handed, but how and when this bias emerges during human ontogenesis is still unclear. We propose an approach that explains postnatal handedness starting from 18 gestational weeks using a kinematic analysis of different fetal arm movements recorded during ultrasonography. Based on the hand dominance reported postnatally at age 9, the fetuses were classified as right-handed (86%) or left-handed, in line with population data. We revealed that both right-handed and left-handed fetuses were faster to reach to targets requiring greater precision (i.e., eye and mouth), with their dominant (vs. non-dominant) hand. By using either movement times or deceleration estimates, handedness can be inferred with a classification accuracy ranging from 89 to 100% from gestational week 18. The reliability of this inference hints to the yet unexplored potential of standard ultrasonography to advance our understanding of prenatal life.
