A battery of neuropsychological tests was administered at baseline, postcontrol period, and posttraining period to 24 drug-refractory subjects with epilepsy participating in a study of sensorimotor electroencephalographic (EEG) normalization feedback training. Results revealed the following. First, subjects exhibited significant baseline deficits in psychosocial, cognitive and motor functioning. Second, certain tests discriminated subjects before training who were subsequently above and below the median in seizure reduction following EEG training. Subjects who showed the greatest seizure reduction performed better on a test of general problem-solving ability but not on other cognitive tests and worse on tests involving strong motor components and were more intact psychosocially. These subjects also took significantly fewer medications in combination than did less successful subjects. Third, improvement on several measures occurred following participation in the study. Cognitive and motor functioning improved only in subjects with the greatest seizure reduction and only after actual training as opposed to control conditions. Psychological functioning, as measured by the Minnesota Multiphasic Personality Inventory (MMPI) improved in both outcome groups. MMPI improvement, unlike cognitive improvement, was as likely to occur after control conditions, when seizure reduction had not yet occurred, as after EEG training. Thus, MMPI changes apparently reflected the nonspecific benefits of participation in this study.

This paper presents a critical review of various attempts at computerized analysis of abnormal electroencephalograms (EEGs). A description of normal and abnormal EEGs from the viewpoint of the clinician is presented at first, along with guidelines used in the visual detection and quantification of EEG abnormalities, followed by a brief review of some important computerized methodologies for clinical EEG analysis. Automated detection and quantification of epileptogenic EEG transients and seizures are reviewed next, and digital computer (software) as well as hardwired systems are presented. Computerized techniques for the quantification of abnormal EEGs in cerebrovascular disorders and coma, metabolic disorders, and for the localization of brain lesions and tumors are presented as well. Future directions and the general problem of man-machine agreement are elaborated upon.

Barbexaclone is a salt compound of phenobarbital and propylhexedrine (a drug with indirect sympathomimetic properties). Due to the presence of the psychostimulating agent, propylhexedrine, this drug has less of a sedative effect and is well tolerated, compared to phenobarbital. Barbexaclone was widely used in Turkey until 2009 when its production ended, however, it gave rise to an epidemic for which we were not prepared. Since then, no standardised management protocol has been developed and each patient has been evaluated individually, thereby creating tailor-made solutions based on the extent of each patient's supply of remaining drug (from a few tablets to a stock which might last for six months). The rate of seizure freedom was 37.7% under barbexaclone treatment and dropped to 32.2% in the follow-up period after discontinuation of the drug. In the majority of cases, a new antiepileptic drug was added and this was commonly levetiracetam, a more expensive drug. In this article, we share our experiences of a general problem: the withdrawal of an antiepileptic drug from the market. Although there was prior notification regarding barbexaclone withdrawal, it was not possible to contact all patients since such a database is not available in Turkey. Although no conclusions regarding the efficacy of the drug or comparison of efficacy with other antiepileptic drugs is provided, it is nonetheless noteworthy to share these experiences since some patients had lost seizure control for reasons that could not be explained.
