A historical essay is presented relating concepts of epilepsy, hysteria, and "possession." The designation "hysteroepilepsy" is placed into the context of combined phenomena in individual subject instances. An association of psychotic states resembling a schizoprenic disorder is indicated as occurring in certain epileptic patients, especially some complex partial seizures (i.e., temporal lobe-psychomotor type). Phenomena of possession may appear within any of these entities. Differential diagnosis now is aided greatly by ulilization of monitoring with combined split screen television viewing and recording of the patient's behavior and the concomitant electroencephalogram. Treatment is directed both medically and toward alleviation of contributing and precipitating psychological and sociological factors.

The EEG findings in waking, sleep, and sphenoidal electrode recordings in 96 patients with partial epileptic seizures with complex symptoms, who, after a median interval of 18 years developed paranoid/hallucinatory psychosis, were compared with the findings from a group of patients without psychosis, who had had the same type of epilepsy in median 24 years. There were no significant differences between the two groups with regard to median age at onset of epilepsy or complex partial seizures, age, or duration of epilepsy at time of examination. The psychotic patients had a significant preponderance of temporal medio-basal spike foci, recorded on the sphenoidal electrode, indicating deep temporal lobe dysfunction as an important factor in the pathogenesis of psychosis. A significant higher frequency of bilateral and multiple spike foci, together with a significant frequency of slow-wave admixture to the waking background EEG activity, indicated more extensive and severe epileptogenic lesions in the psychotic patients. There was no correlation between psychosis and unilateral EEG-foci in either temporal lobe.

The EEGs of hospitalized psychotic boys were analyzed quantitatively by means of visual evaluation, analog frequency analysis, and digital computer period analysis and were compared with those of age- and sex-matched normals. Visual evaluation of the records demonstrated that psychotic children have significantly more beta activity as well as fewer alpha bursts than normal controls. EEG analog frequency analysis showed that psychotic children have a greater percentage of total voltage in the 3-5 cps and 13-33 cps bands, while they show less voltage in the 6-12 cps bands as compared with normal controls. Digital computer period analysis demonstrated more slow, less alpha, and more fast activity, as well as a greater average frequency and frequency deviation in both the primary wave and first derivative measurements in psychotic children than normals, while normals showed a trend towards higher amplitude and amplitude variability. The similarity of the EEG differences between psychotic and normal children to those differences observed between adult chronic schizophrenics and normals, as well as to those between children of "high risk" for becoming schizophrenic and controls, suggests that the above described findings are characteristic for the pathophysiology of schizophrenia.

A tenth case (a subtype of complex partial seizures) is proposed as a Limbic (?) Psychotic Trigger Reaction. Upon crying, an infant girl was hit fatally by her devoted father while he was off anticonvulsants prescribed for Jacksonian and petit mal (?) seizures with "porencephalic cyst involving motor cortex and limbic system." Crying revived traumatic memories of frequently repeated ("kindling") experiences of his mother crying when hit by his father, in turn sometimes hit by patient while helping the mother. Hitting also had been helpful (cognitive mismatch between helpful and harmful hitting) during the victim's accidental choking 11 days earlier. This had occurred on the same day his distant mother died. Two days later he attempted suicide with anticonvulsants. Symptoms of the well remembered, unmotivated infanticide included flat affect, olfactory and command hallucinations, and delusions of grandeur (his mother leaving him millions and power).

Slow rhythmic activity (SRA) in the frequency range from 2.5 to 5.0 cps was studied in 20 subjects (Ss) in order to examine its effect upon sensorimotor reactions and its possible relationship to psychological findings. With monopolar EEG derivations, maximal power density of SRA is found in frontal regions, whereas bipolar leads reveal maximum occurrence of SRA over posterior areas. Reaction times (RT) to visual and auditory stimuli increase significantly during the occurrence of SRA; the amount of this prolongation (ca. 74 ms) is independent of stimulus modality but significantly correlates with SRA frequency: the lower the frequency, the higher the RT increment. In psychological tests, most Ss with SRA displayed disturbances of emotionality as well as 'pathological' values in the subscales hysteria, hypochondria, psychasthenia, and paranoia, but none of our Ss was diagnosed as psychotic. There is a high correlation between the SRA frequency and the extent of psychological deviations: Ss with low SRA frequency values are more likely to reveal psychological disturbances than Ss with high SRA frequency. The possible origin and physiological impact of SRA is discussed and the desirability of further neurophysiological studies is emphasized.

Case report of a 35 years old patient, who, without previous history of epilepsy, within two years experienced two long-lasting psychotic episodes due to non-convulsive status epilepticus with complex partial seizures. During the second psychotic episode she developed ictal vegetative phenomena such as profuse sweating, flush, apnoea, and, above all and most alarming, periods of severe bradycardia and asystolia with clinical signs of syncope. Ictal asystolia, though being an uncommon sing of epileptic seizures, may be one cause of sudden unexpected death in epileptics.

This report is a phenomenological study of 20 cases of temporal lobe disorders manifested as complex partial seizures. The major behavioral symptoms observed were episodic affective disturbances, episodic cognitive disturbances, and "spells," with normal functioning between episodes. The remarkable similarity of this phenomenology to what has been described as atypical or episodic psychosis provides a possible theoretical link to the etiology of atypical psychosis. These cases also establish atypical psychosis as an entity clearly different from the other major psychoses.

Depression is common in epileptics, but few studies of this relationship exist. We investigated the prevalence of depression in comparably disabled outpatients and its phenomenology in psychiatrically hospitalized inpatients. Fifty-five percent of 175 outpatient epileptics and 30% of 70 matched controls reported depression; 30% of epileptics vs 7% of controls reported prior suicide attempts. Epileptics were four times more likely to have been hospitalized for depression than nonepileptics. Twenty depressed epileptic inpatients were characterized by "endogenous" rather than "neurotic" features with more psychotic traits, paranoia, and underlying chronic dysthymia. Sixteen patients had complex partial seizures, and ten of 11 patients had a lateralized electroencephalographic focus lateralized to the left hemisphere. These results suggest a specific epileptic psychosyndrome due to limbic dysfunction.

Data are presented on 24 patients with epilepsy and psychosis whose clinical presentation was rated using the Present State Examination (PSE). Seventeen had complex partial seizures and a diagnosis of temporal lobe epilepsy, seven had generalised epilepsy. An association between a CATEGO category of nuclear schizophrenia (NS) and a lesion of the left side was noted. No clear link between depressive symptoms and a right-sided focus was discovered. Affective disorders were noted in both groups of epileptic patients, although paranoid psychoses were commoner in the temporal lobe group. There was also a tendency for the latter to have more delusions of persecution, ideas of reference, and special features of depression. The group rated as NS appear less likely to show evidence of intellectual deterioration than the other psychotic patients; in addition, the interval between the onset of their epilepsy and the onset of their psychosis is shorter. Radiological assessment by CAT reveals few differences between groups, but the psychotic samples do show higher than expected values on a number of variables, in particular the bilateral septum-caudate distance and the size of the third and fourth ventricle.

A 36-year-old woman was treated for a wide variety of psychiatric illnesses over a span of two decades before a diagnosis of complex partial seizures was made. Her history included poor impulse control, rage attacks, multiple suicide attempts, rapid mood swings, depression, and psychotic episodes. Bulimia, panic attacks, severe obsessive-compulsive symptoms, and multiple somatic complaints were also present. In retrospect, these symptoms could be attributed to complex partial seizures with cognitive and affective symptomatology, automatisms, and psychosensory symptoms, and were controlled by anticonvulsant medications. Therefore, so-called "purely" psychiatric disorders should not be diagnosed before a diagnosis of limbic epilepsy (however, this might be labeled, e.g., complex partial seizure, psychomotor seizure, psychical seizure, or temporal lobe epilepsy) has been considered.
