Also referred to as muina
The underlying cause of these syndromes is thought to be strongly experienced anger or rage. Anger is viewed among many Latino groups as a particularly powerful emotion that can have direct effects on the body and can exacerbate existing symptoms. The major effect of anger is to disturb core body balances (which are understood as a balance between hot and cold valences in the body and between the material and spiritual aspects of the body). Symptoms can include acute nervous tension, headache, screaming, stomach disturbances, and, in more severe cases, loss of consciousness. Chronic fatigue may result from the acute episode.
