On Morel's 'épilepsie larvée: the first Danish epileptologist Frederik Hallager's opposition in 1884 against Morel's psychical epileptic equivalents.

In 1860 B. A. Morel published some cases of masked epilepsy, i.e., paroxysmal behaviour disturbances or "epileptic equivalents". The majority behaved criminally. Hughlings Jackson opposed and Hallager showed that all the cases related later as épilepsie larvée could be explained as postepileptic attacks, general paralysis, paradoxical normalization, schizophrenia, mania and otherwise. True criminal behaviour was exceptional. The present author agreed. There is no need for épilepsie larvée. It is discussed whether Blumer's recent "Paroxystic neurobehaviour disorder" will revive "Morel's disorder".
