[Hallucinations of body magnification in migraine]

Hallucinations of body magnification, representing aura symptoms of migraine, are recorded in 2 original observations and in 32 cases reported in the clinical literature. These hallucinations represent an isolated neuropsychological symptom that can be conceived as a disorder of the body schema. The head and the hands are the anatomic regions that are most frequently affected. This parallels the dominance of representation of these regions in the sensory cerebral cortex. Hallucinations of body magnification frequently co-occur with aura symptoms of basilar migraine, which is compatible with the hypothesis of a localisation of these hallucinations in the regions of the thalamus and the parieto-temporo-occipital cortex.
