title: [Left-handedness and its clinical significance].
abstract: The occurrence rate of lefthanded persons is estimated to range between 4-8% in the human population, according to the criteria used. On assessing pathological lefthandedness, the role of all factors affecting the development of a lefthanded subject has to be considered. There are morphological differences between left- and righthanded subjects. The differences in neuropsychologie performance of the right and left hemisphere are less pronounced in lefthanded than in righthanded persons. A relationship between lefthandedness and the occurrence of some pathological conditions has been established. On sociobiological evaluation it appears more appropriate to consider lefthandedness as a continuous quantitative manifestation of handedness rather than a separate biological variant of man.
