<unk>  is similar to other complex tics including echolalia, palilalia and coprolalia. It is defined as compulsive shouting, which can be in the form of swearing, grunting or barking. The subject may appear flushed, and<unk>  can occur with increasing frequency if the person is agitated. The duration of the incident depends on the individual, but it can be characterized by a peak period, followed by intermittent remissions of less intensity. Although the individual may sound like they are in pain, there does not appear to be any actual physical discomfort. The shouting can be accompanied by other symptoms, such as oculogyric crises or other involuntary movements. The presentation of<unk>  has been compared to temporal lobe epilepsy, although the two can be distinguished by the duration of the attack and the fact that the patient experiencing<unk>  appears to retain consciousness. A 1961 report by Wohlfart described a postman known as K.R. who contracted encephalitis lethargica at the age of 12. While he reported no significant ill effects from the disease, he was irritable and complained of fatigue for years after recovering. At 22, the patient received a head injury, though he did not sustain a concussion or cranial fracture from the incident. Six months later, he developed oculogyric spasms, as well as dyskinesias of the mouth and tongue. At the age of 44, the patient experienced his first bout of<unk> . He remained conscious for the entire incident, while he shouted for about half an hour and appeared "crazy" for hours after the shouting ended. The next day, he felt better, though he did report being tired. The patient continued to suffer from the attacks for the next few years before coming under observation of Wohlfart and colleagues. He subsequently served as a model to describe<unk>  from beginning to end. According to Wohlfart's account of one patient, onset is sometimes characterized by absentmindedness: the patient K.R. stared straight ahead and only responded in monosyllables in the minutes leading up to the incident. An oculogyric spasm then developed, during which he demonstrated echolalia. After 15 minutes, further motor symptoms arose, with the patient making small jerky motions with his arms that developed into larger, circular movements. At 20 minutes, the attack reached its peak, with the patient becoming bright red and making large compulsive movements with his arms and kicking his legs. He began swearing, shouting, screaming, grunting and barking loudly, with intermittent bouts of heavy panting. He remarked upon the people present, with his comments being related to the situation in question. He attempted at times to excuse his behavior. Afterwards the patient was able to provide an account of what had happened. Wohlfart et al. concluded that the patient was aware of his surroundings during the attack, with the patient even expressing concern over missing a scheduled appointment; the patient demonstrated some ability to control his behavior when spoken to in a sharp tone, but he would inevitably return to his shouting and movements after a few seconds of stillness. The episode lasted an hour and a half and was accompanied by salivation, sweating, and tachycardia. The peak of the attack lasted 30 minutes; the intensity then started to subside, though the patient still exhibited bouts of shouting and movement after several minutes of remission. The remission periods between the shouting episodes became longer, until the entire attack was over in about an hour and a half.
