[Preparoxysmal fits of laughter from misformation of the hypothalamus (author's transl)].
Fits of laughter have been described in a number of instances with a differentiation made between primary and secondary fits. Fits of laughter in the case of pubertas praecox resulting from a hyperplastic deformation at the base of the IIIrd ventricle have not been observed as yet. The case here described shows that fits of laughter of this type can be observed prior to commencement of the actual epileptic fit itself. A short description if given of how normal laughing and crying comes into being, referring to the relevant literature.
