In this study, a multivariate model that collectively takes into account the effects of multiple morphological variables, including the cortical thickness, surface area, and curvature index, was used to investigate the hemispheric asymmetry on a longitudinal database to distinguish MCI converters from nonconverters.
Nevertheless, EDA records have been evaluated in the investigation of diseases such as hemispheric asymmetry, anxiety, depression and schizophrenia [3].
They found that high-functioning older adults showed strong bilateral prefrontal activations whereas young subjects involved only a smaller prefrontal circuit in the right hemisphere and proposed that in aging subjects, there could be a Hemispheric Asymmetry Reduction in Older Adults (HAROLD model) for some cognitive functions.
A point of interest is to what extent this hemispheric asymmetry of the motor mechanisms is translated into a difference of performance of the two upper limbs.
Hemispheric lateralization, also known as hemispheric asymmetry, refers to the structural or morphological differences between the right and left hemispheres, as well as the differences in the information processing capacity between the hemispheres [1].
However, we can only speculate that the mTBI caused the hemispheric asymmetry, given the lack of an isolated mTBI group.
Gur et al., (1982) showed that the direction and degree of hemispheric asymmetry of cerebral blood flow are influenced by gender and upper limb preferential use.

By contrast, other researchers failed to find evidence in favor of the predicted hemispheric asymmetry, suggesting that the RH and LH have the same ability to manage with global and local information (Alarcon & Blanca, 2000; Alivisatos & Wilding, 1982; Amirkhiabani, 1998; Arnau, Blanca, & Salvador, 1992b; Blanca, 1992; Blanca & Alarcon, 2002; Boles, 1984; Boles & Karner, 1996; Polich & Aguilar, 1990; Van Kleeck, 1989).
