[Variability in seizure phenomenology in the same epileptic patient].
There are many different causes for an alternate outbreak of different seizure manifestations in the same patient. According to Herpin's 'law of identity', this is more a question of differing degrees of intensity of the same seizure type. Subsequently, minor or partial seizures are to be interpreted as rudimentary forms of 'major' seizures. This may be true for some, but not for all cases. It would be daring to maintain that a typical absence is a rudimentary form of a 'grand mal' seizure. Their mutual pathogenetic relations are unknown. A series of other cases would likewise go beyond the scope of Herpin's law. A patient can show, even during a cerebral condition of the same etiology, several different localized epileptogenic foci which 'flame up' alternately and initiate different types of seizures. Progressive cerebral illnesses can lead to a change in the original seizure symptoms and can also trigger off additional seizure forms. This can occasionally occur during medication. Finally, it is necessary to consider the possibility of an alternate outbreak of epileptic and nonepileptic seizures in the same patient.
