An adolescent girl with a previous history of trance-like states and a strong family history of epilepsy developed a pattern of recurrent brief psychotic episodes. These episodes seemed to coincide with her monthly menstrual periods, and after four to seven days of bizzare, catatonic behavior, she would return to a normal state. These episodes have been virtually eliminated by maintenance of a therapeutic blood level of phenytoin. The case is discussed in the light of the complex interrelationship of seizures, menstrual hormonal changes, and behavior.

This case study describes in detail two autistic siblings who were mentioned in Rimland's analysis of checklists for psychotic children, as the only pair of classically early infantile autistic siblings (Rimland, 1971). One of the children, a nonverbal girl, now 13 years old, who developed epileptic seizures at age 41/2, shows all symptoms of early infantile autism even today. Her brother, now 24 years old, however, does not fit any of the known psychopathological patterns of childhood. The boy showed all symptoms of early infantile autism, but also some of the main characteristics of childhood schizophrenia and austic psychopathy. It is suggested that we are dealing perhaps with an unusual mixed type falling within a broad category of genetically determined types of autistic disorders.

It is necessary to classify the epileptic psychoses before starting a comparative study between psychopathological and electroencephalographic findings. The knowledge of the epileptic psychoses is at the moment too incomplete for a systematic order following aetiological or topic aspects. The traditionally system of epileptic psychoses distributes in chronic and episodic, phasic, especially circular, reversible and irreversible psychopathological manifestations. We differentiate psychotic states with or without disturbances of consciousness. Well-known in EEG studies of symptomatic and endogenic psychoses is, that in these psychoses the same clinical syndrom can be related to normal and to pathological electroencephalographic findings. This contradiction could often be explained when the activity of the psychoses was taken into consideration. The activity of the psychoses is to be determined by the duration, number, intensity and variability of the psychopathological symptoms. From his own investigations from 30 patients with schizophreniform epileptic psychoses, episode affective disorders and both depressive and manic psychoses, it could be shown, that normal EEGs are markedly infrequent. Most often they occur in subacute schizophreniform epileptic psychoses. The EEG of active and particularly of schizophreniform epileptic psychoses is most often characterized by simultaneous appearance of sharp waves, paroxysmal dysrhythmias and abnormal rhythm formations. Active schizophreniform psychoses correlate usually with abnormal rhythms. These abnormal rhythms ("parenrhythmien") diminish parallel with loss of activity of the psychotic process, are correspondingly seldom seen in subacute psychoses, and are not demonstrable in inactive psychoses. The experience of an alternating correspondence between epileptic psychoses and frequency of seizures could be confirmed.

The effect of corticosteroid therapy in 28 patients with 52 episodes of neuropyciatric disease in systemic lupus erythematosus (SLE) was elevated. Categories of organic central nervous system disease were seizures (eight patients), organic brain syndromes (nine patients), aseptic meningitis (four patients) and a variety of focal neurologic findings (seven patinets). Fourteen pateints had 15 episodes of functional psychosis without other evidence of neurologic disease. Although there was a general correlation between clinical and serologic evidnce of active SLE and the development of organic neurolgic disease, there was no evidence that therapy with very large doses of corticosteroids was beneficial. Of the deaths in this series, two were due to probable active SLE involving the central nervous system wheras five were attributable to complications of therapy. The long-term morbidity, likewise, was high in the patients who recieved large doses of corticosteroids. In all, 12 patients had major complications of corticosteroid therapy. Functional psychosis was usually preciptated by corticsoteroid therapy and respond to a reduction in steroid dosage and administration of psychotropic drugs.

Transient psychotic episodes may result from continuous cerebral epileptiform discharges unaccompanied by clinically observed seizures. Such episodes may mimic depressive, hysterical and schizophrenic psychosis and delirium. I describe two patients here and review eight patient histories from the literature. Diagnosis is established by use of electroencephalography during the psychotic episode. Correct diagnosis is essential because specific treatment is available and additional episodes may be prevented by appropriate long-term anticonvulsant therapy.

Magnesium is an essential cofactor for many enzymatic reactions, especially those involved in energy metabolism. Deficits of magnesium are prevalent due to inadequate intake or malabsorption and due to the renal loss of magnesium that occurs in certain disease states (alcoholism, diabetes) and with drug therapy (diuretics, aminoglycosides, cisplatin, digoxin, cyclosporin, amphotericin B). Protracted deficits of magnesium in humans and animals result in neurological disturbances, including hyperexcitability, convulsions and various psychiatric symptoms ranging from apathy to psychosis, some of which can be reversed with magnesium supplementation, others requiring correction of the dysregulation mechanism. Although the role of magnesium in neuronal function is not completely understood, a lowering of CSF or brain magnesium can induce epileptiform activity and there is an association between decreased CSF magnesium and the development of seizures. CSF concentrations of magnesium are normally higher than magnesium plasma ultrafiltrate (diffusible) concentrations due to the active transport of magnesium across the blood-brain barrier. Under conditions of magnesium deficiency, CSF concentrations decline, although this decline lags behind and is less pronounced than the changes observed in plasma magnesium concentrations. Decreases in CSF magnesium concentrations correlate with the alterations observed in extracellular brain magnesium concentrations in animals following the dietary deprivation of magnesium. CSF magnesium concentrations can readily be repleted following magnesium supplementation, although high dose magnesium therapy, such as that used in the treatment of convulsions in eclampsia, will only increase CSF magnesium concentrations to a very limited degree (approximately 11-18 per cent) above physiological concentrations. Greater increases in CSF magnesium may occur in neonates since neonatal swine, following treatment with magnesium, have CSF magnesium concentrations that are similar to their plasma concentrations. There has been a recent resurgence of interest in magnesium deficiency and its neurological consequences due to the finding that magnesium, at physiological concentrations, blocks N-methyl-D-aspartate (NMDA) receptors in neurones. NMDA receptors are normally activated by glutamate and/or aspartate which represent the principal neurotransmitters for excitatory synaptic transmission in vertebrate CNS. Magnesium deficiency produces epileptiform activity in the CNS which can be blocked by NMDA receptor antagonists. Other mechanisms, including alterations in Na+/K(+)-ATPase activity, cAMP/cGMP concentrations and calcium currents in pre- and postsynaptic membranes, may also be at least partially responsible for the neuronal effects associated with low brain magnesium. Further studies are necessary to increase our understanding of the neurological implications of magnesium deficit in the central nervous system.

Some data from the literature on adolescent suicidal behaviour are reported: incidence, employed methods, warning signs, risk factors, some psychodynamic aspects. The purpose of this work is to contribute to the study on this matter by a research on 33 adolescents (12 males, 21 females: mean age 14 years, range 11.2-17 years) examined because of suicidal behaviour. The study method includes: anamnesis, psychodiagnostic inquiry, family and environmental investigation, psychiatric evaluation. Suicidal behaviour is characterized by low levels of determined self-elimination intent ("suicidal gestures") in 36% of cases (1 male, 11 females). Relapses are found in 35% of cases, with death in 1 case. The most frequently used methods is drug poisoning (65%). Most common place where suicidal behaviour takes place is at home (82%). Most show warning signs especially verbal threats. Some problem in the family situation (conflicts in the parental couple or between parents and children, psychopathologic disturbances in the parents) and frequent difficulties in school and social adjustment are evident. In 45% a depressed state was noted, in the other cases several psychopathologic disturbances have been found: hysteric neurosis, borderline personality, psychosis. In 30% of cases symptoms coexist with a self-injuring meanings (nervous anorexia, pseudo-epileptic seizures). Prevalent psychodynamic characteristics are: vulnerability in facing frustrating situations and research of support from inadequate parental figures: displacement from hetero-direct aggressive drives to an expiratory or revengeful self wounding behaviour. Some criteria for an emergency care and for a middle to long term treatment are mentioned, and the opportunity for collaboration between pediatricians and psychotherapists is suggested.

The authors report 6 cases of acute frontal syndrome following severe seizures of frontal origin. The study of the 6 cases shows the place of disorders in affectivity, behavior, judgement and motor activity; such features changing over time. The relationship between the frontal syndrome and epilepsy is suggested by the fact that the frontal syndrome appears after an increased frequency of frontal seizures, with prolonged discharges of generalized or frontal spikes. The frontal syndrome disappears slowly with the epileptic discharges, and no frontal lesion is found on CT-Scan. Such cases suggest that the frontal syndrome is functional, linked to the localization of the epileptic discharges; it may be regarded as a post-critic deficit, and must be differentiated from a post-critic delirium or a psychotic state.

We analyzed 71 patients (45 males and 26 females) with Wilson's disease (WD) who were seen at our hospital from 1979 through 1990. The mean age at onset was 18.1 +/- 6.5 years, with 17.0 +/- 6.6 years for males and 20.2 +/- 5.7 years for females. The mean age at the time of diagnosis was 21.0 +/- 6.3 years. Hepatic WD was the most frequent mode of presentation in childhood with a mean age of 15.5 +/- 6.0 years, while neurologic WD tended to occur in adolescence with a mean age of 21.0 +/- 8.9 years. The ages of onset were 12.5 +/- 0.5 years for renal WD and 25.3 +/- 2.4 years for psychiatric WD. The common initial symptoms were neurologic and hepatobiliary. In addition, hematologic and renal disorders were also common during evaluation. The neurologic findings at the time of diagnosis were tremors (66.2%), dysarthria (56.3%), gait disturbances (46.5%), dystonia (42.3%) and decreased facial expressions (40.8%). Less frequent but notable neurologic presentations were psychosis (11.3%), epileptic seizures (5.6%) and hypokalemic periodic paralysis (1.4%). When compared with two previous large Chinese series, the present data show a male preponderance, an earlier age of onset for males and higher incidences of hepatic, hematologic and renal involvement. The possible reasons for the discrepancies between the present study and previous Chinese series are discussed.

One hundred fifteen consecutive patients in the Austin Hospital Comprehensive Epilepsy Program (Melbourne, Australia) were surveyed to document the psychosocial and rehabilitation difficulties after temporal lobectomy. During the follow-up period (mean 4 years) 3 patients died, 5 patients were lost to follow-up, and 107 patients with family and friends were interviewed. Eighty-four patients (78%) had been seizure-free for the year preceding the interview; 13 others had seizure reduction greater than 75%. Success in ablation or reduction in seizures correlated with the amount of postoperative gain, but in this series, analysis of work and dependency outcome did not emphasize areas of success. Although improvement in work and financial status, interpersonal relations and sexuality were all recorded, successful patients deemed that most advance had been made in the areas of newly acquired independence, enhanced career potential, and social freedom. Significant postoperative anxiety, especially after left temporal lobectomy, was noted, possibly explained by benzodiazepine antiepileptic drug (AED) discontinuation. Although 1 patient committed suicide, neither depression nor psychosis was common in the rehabilitation period, in contrast to results in previous series. Significant sociodomestic problems emerged from this survey, however: 35% of patients considered successes reported postoperative problems stemming from the necessity to restructure family dynamics; in 6%, this resulted in divorce. Moreover, 20% of patients and relatives reported significant behavioral problems in coping with the seizure-free lifestyle. Finally, the problems of the worsened situation after surgical failure indicated the counterproductive potential of ineffective lobectomy. These results indicate the necessity for a preoperative counseling program to prevent these problems.
