Lycanthropy is a kind of melancholy making the affected persons wander at night-time, visiting the tombs and the deserts like wolves, and come back in the morning as their human figure and stay at home. In any case, they have ulcerated legs and feet because of falls on stones and thorns; they have dry eyes and tongue and feeble vision… Some patients avoid speaking and remain silent and sad while others try to converse with people.
Johannes Actuarius, Therapeutike Methodos
Werewolf diagnosis is tricky! Look for dry eyes, dry mouth, and [checks notes] ah yes, visiting tombs at night and returning in human form in the morning.
