Abstract
Witzelsucht and moria are time-honored neurobehavioral terms. Witzelsucht is a tendency to tell inappropriate jokes, and moria is euphoric behavior. Focal right-orbitofrontal parenchymal lesion is often the anatomical substrate for these behavioral attitudes. This case report presents a patient with a longstanding witzelsucht-moria behavior. Single photon emission computerized tomography (SPECT) showed hypoperfused right-frontoparietal area in the absence of structural damage.Keywords
