Neurological morbidity of severe epilepsy.
The "severity" of a disease is a relative expression and its definition will vary depending on the perspective of the observer. The patient's subjective perception of the disease, the way it is regarded socially by the community, and the doctor's objective assessment rarely coincide. In fact, they are frequently diametrically opposed. As far as the patient's personal perception of epilepsy is concerned, there has apparently been no satisfactory attempt thus far at a systematic grading of the subjective handicap, despite the growth of interest in psychological matters and the self-help movement. Similarly, social ability or disability cannot be adequately assessed on the basis of medical criteria such as frequency and type of seizures. We present a grading system which will serve as an example of an appropriate method of assessing social abilities, and which will permit the patient's occupational potential to be estimated in relation to the risk of accidents resulting from seizures. From the medical point of view, the impairment of a patient's abilities due to epilepsy is a function of the patient's responsiveness to treatment. We present a critical review of the factors which have an effect on the therapeutic prognosis: the causes of epilepsy, underlying structural lesions, the incidence of convulsive status epilepticus, various types of attacks, and the different epileptic syndromes. Taking two examples--epilepsy presenting in the form of absence and epilepsy with complex focal seizures--we show that ultimately the "severity of epilepsy" can only be defined from the medical standpoint on the basis of several factors whose value is of a predictive nature.
