[Atypical symptoms in brain tumour cases. A contribution to their topography (author's transl)].

By autopsy 38 brain tumour cases out of 207 (22.5%) showed atypical, i.e., psychical symptoms and were clinically found to be brain-organic syndromes. These changes most frequently occurred with glioblastomas and meningiomas; but principally they were found with all tumour types. All the tumours destroyed, respectively, touched parts of the limbic system. Emotional and menestic troubles emerged in these cases. It is suggested than an injury of the limbic system is responsible for an exclusive or prevailing psychical symptomatology.
