The distinction between hysterical and organically determined epileptic seizures may be more difficult than is sometimes supposed, and misdiagnosis can have dire consequences. Hysterical seizures may on occasions present as life-threatening crises requiring urgent and intensive treatment. Three such cases, each of which received the diagnosis of status epilepticus, are reported, and their management is discussed.

Our experience of using video-audio/EEG monitoring in the diagnosis and management of epilepsy at The Queen Elizabeth Hospital Comprehensive Epilepsy Service from March 1987 to December 1990 is described. We performed 75 long term monitoring studies on a total of 66 patients. Following monitoring, a change in seizure diagnosis was made in 21 of 66 patients (32%). Pseudoseizures were diagnosed in 17 patients. A change in management as a consequence of monitoring occurred in 53 of the 66 patients (80%). The referring neurologists considered that 56 of the 75 studies (75%) were successful. The investigational technique is effective and is particularly useful for the diagnosis of pseudoseizures.

We evaluated 30 patients with a tentative diagnosis of epilepsy who did not respond to anticonvulsant therapy. Crisis were induced through suggestion with simultaneous EEG recording. Pseudoseizures were revealed in 10 patients. A depressive syndrome was present in 5 and other psychiatric disorders in the rest. Psychiatric therapy was effective in suppressing seizures in 7 compliant patients. We feel that suggestive induction of crisis is an effective diagnostic tool for identification of pseudoseizures.

Differentiating seizures from pseudoseizures frequently is challenging in very young children manifesting repetitive, stereotypic behavior. Using video electroencephalographic recording, we evaluated 60 patients, younger than 10 years of age, with episodic signs and symptoms believed to be seizures despite repeatedly normal routine electroencephalograms. Nine patients (15%) had simple partial and atypical absence seizures. Twenty-four patients (40%) had pseudoseizures presenting as rhythmic movements or staring. Pseudoseizure frequency was greater than the frequency of true seizures; brief staring episodes were common. Motor pseudoseizures usually were of longer duration than true seizures and could be brought on with verbal encouragement. Furthermore, the stereotypic motor presentations were quite different from those of true motor seizures but were difficult to recognize from historic, clinical, and routine electroencephalographic data. Symptomatic patients can be clinically diagnosed by analyzing confirmed episodes with video electroencephalography.

Pseudoseizures, formerly called hysterical seizures, have become an acknowledged clinical entity in their own right. Diagnosis of pseudoseizures is a complex process, depending primarily on clinical neurologic observation of the spell pattern and negative response to anticonvulsant therapy. Diagnosis is aided by psychiatric evidence of psychopathology, and in difficult cases, by video/EEG observation of actual spells, either spontaneous or induced by saline infusion or hypnosis. Exposure to some model of spell behavior is considered important in the development of most cases of pseudoseizures. Pseudoseizures are difficult to treat successfully, and exploratory attempts at treatment have included hypnosis and behavior therapy. Pseudoseizures may represent either conversion disorder or dissociative disorder.

Pseudoseizures should be considered in the differential diagnosis of intractable seizures. Incorrect diagnosis may result in incorrect management, with the patient unnecessarily exposed to side effects of drugs. The authors report on three patients who presented with uncontrolled seizures originally diagnosed and managed as status epilepticus. Electroencephalography performed during provoked attacks led to a diagnosis of pseudoseizures. Psychiatric assessment revealed psychologic disorders. The patients received supportive therapy, and the pseudoseizures stopped.

Failure to recognize pseudoseizures is a common problem, affecting both epileptic patients who additionally have pseudoseizures and nonepileptic patients inappropriately called epileptic. Pseudoseizures most commonly mimic generalized tonic-clonic (GTC, "grand mal") seizures or complex-partial seizures. Several patients whose speudoseizures were not recognized are described. Adhering to logical principles of diagnosis for epilepsy, as for other medical problems, and remaining aware of basic beahvioral dynamics should eliminate the confusion between pseudoseizures and epileptic seizures.

Pseudoseizures, clinical events that superficially resemble epileptic attacks but which are not associated with central nervous system paroxysmal activity, are often difficult to differentiate from epileptic seizures. To evaluate the frequency and clinical manifestations of pseudoseizures in children with intractable seizures, children admitted to a Comprehensive Epilepsy Unit received prolonged simultaneous EEG telemetry and video recording. Pseudoseizures occurred in 11 of 53 pediatric patients admitted during the study period. Eight of the 11 patients with pseudoseizures also had documented epileptic seizures. Clinical characteristics of pseudoseizures and epileptic seizures documented by TEEG-VR were compared. Degree and duration of the postictal state, incontinence, combativeness, relationship to stress, and response to anticonvulsant medication were useful differentiating criteria. Pseudoseizures are not unusual in pediatric patients, often occur concurrently with epileptic seizures, and may be difficult to diagnose. However, careful clinical observation may offer clues in differentiating pseudoseizures from epileptic seizures.

We report two patients with epilepsy with pseudoseizures at age 6 years. Both presented with intractable staring spells. Pseudoseizures were provoked and aborted by suggestion, leading to the diagnosis. In both patients, evidence of a neuropsychological disturbance was later found and psychotherapy started. Monitoring of intractable staring episodes is recommended prior to escalating antiepileptic drug levels or resorting to polytherapy. In addition, differentiation from other non-epileptic phenomena is necessary to initiate proper therapy.

Previous research in the area of pseudoseizures has focused upon their phenomenology and the characteristics of the individual with pseudoseizures. This study set out to examine the role of pseudoseizure behaviour in fulfilling a function within the family context. Pseudoseizure patients, patients with epilepsy and healthy controls completed questionnaires measuring the following variables--anxiety and depression, locus of control, self-esteem, family characteristics and perceived seizure severity. People with pseudoseizures perceived their families as displaying less commitment and support to each other (family Cohesion scale) and less emphasis on ethical issues and values (family Moral-religious scale) than both the epilepsy and the control groups. People with pseudoseizures reported levels of family interest in political, social and recreational activities (family Intellectual-cultural scale) similar to people with epilepsy, both these group scores being lower than the control group. The two patient groups also reported higher depression scores than controls, yet only the epilepsy group had lower self-esteem than the controls. These initial findings support a role of family involvement in therapy for people with pseudoseizures and may lead to a better understanding of the aetiology of pseudoseizures, as well as clarifying characteristics which may well aid the differentiation of pseudoseizures from epilepsy.
