Alterations of consciousness with impaired perception and drive persisting over hours to days can be due to a nonconvulsive status epilepticus. This possibility has to be considered not only in patients with already known epilepsy, but also in those with a negative history for seizure disorders. The immediately recorded electroencephalogram (EEG) provides decisive clues. In the case of petit mal status most frequently appear tiredness, reduced vigilance and lack of drive. The EEG shows a generalized spike-wave activity. In status psychomotoricus, the clinical symptomatology varies from case to case. It can be characterized by anxiety, dreamy states or productive-psychotic states with agitation, automatisms and hallucinations. In the EEG a temporal or temporally-accentuated epileptic activity will be recorded. Transitional and mixed forms of petit mal status and status psychomotoricus can also be found. I.v. injections of benzodiazepines (clonazepam, diazepam) are an appropriate therapy for any type of nonconvulsive status epilepticus. Phenytoin is indicated in status psychomotoricus, but contra-indicated in the case of petit mal status.

Fatigue represents a common side effect of several drugs, however, the underlying mechanisms have not been well identified. A depression of the central nervous system (CNS) and/or changes in peripheral processes have been associated with the development of fatigue. Antiepileptic drugs (AEDs), generally decreasing CNS excitability, are used in the treatment of seizures as well as other neurological and psychiatric diseases. Fatigue is certainly a common AEDs' side effect, although a high degree of variability exists depending on both patients' characteristics and the drug used. Here, we delineate the pathophysiological central and peripheral mechanisms by which AEDs may cause fatigue also reviewing the available clinical data in order to assess a possible AEDs rank and highlight each AEDs related risk. It appears that drugs acting on the GABAergic system have the highest incidence (with tiagabine exception) of fatigue followed by Gabapentin and Levetiracetam whereas drugs mainly inhibiting sodium channels (Carbamazepine, Eslicarbazepine, Lamotrigine, Phenytoin and Valproate) have the lowest. However, the dose used, AEDs related side effects and patients' characteristics might influence the degree of fatigue observed.
