[E.E.G. recordings during the course of a rare disease: piroplasmosis (author's transl)].

Two E.E.G. recordings were made in a patient with human piroplasmosis (babesiosis). They showed signs of vigilance disturbances and generalized abnormalities, together with lateralization in the temporal region, on the right side in the first recording and on the left in the second one. These abnormal E.E.G. findings are reported, even though the clinical signs were not typical of babesiosis, as the biological diagnosis was certain (parasite definitely identified in the red blood cells, severe and progressive parasitic infestation), and it is impossible to evoke other aetiological elements. It is impossible to formulate a valid hypothesis, based on our present knowledge, to explain the mechanisms of this encephalic condition. We can only state the findings without prejudging its direct or indirect nature.
