You are assessing a patient with suspected frontal lobe pathology and want to check for moria. Before revealing the answer, decide what you would look for.

Observe whether the patient persistently makes jokes, puns, or facetious remarks across the interview, including at moments when the topic is serious and humour would not ordinarily be expected. Assess the quality of the humour specifically — does it feel shallow, hollow, or childish rather than reflecting genuine wit or warmth, and does the patient seem unable to engage seriously with a topic without lapsing into joking. Look for other signs suggestive of frontal lobe involvement alongside it, such as disinhibition or impaired social judgement, and take a history and, where relevant, arrange imaging to establish whether a frontal lobe lesion or other pathology is present, since this specific association is part of what distinguishes moria from mood elevation of primarily psychiatric origin.
