This is a report on six psychiatric patients who indulged in excessive ingestion of water and subsequently developed tonic-clonic seizures in the course of the underlying mental disorders. On the basis of the DSM-III criteria, they were diagnosed as follows: schizophrenic disorder, 4; schizo-affective disorder, 1; borderline personality disorder, 1. The levels of serum electrolytes were estimated during five episodes of seizures in three patients. Hyponatremia was a consistent finding (serum sodium: mean = 120.6 mEq/liter). Plasma osmolality and plasma levels of arginine vasopressin (AVP) were determined during two episodes in two patients. The inappropriately high circulating levels of AVP relative to plasma hypoosmolality were documented. However, the response to the overnight fluid deprivation and acute water load during the period of no seizures in two patients revealed no evidence of the persistent SIADH, suggesting the temporal association of hyponatremic encephalopathy with inappropriate AVP secretion. It is not conclusive whether the transient SIADH is the cause or the consequence of hyponatremic encephalopathy, although a delusion or an auditory hallucination could play a critical role in drinking water excessively in three patients.

We present here magnetic resonance imaging (MRI) and single photon emission computed tomography with 123I-N-isopropyl-p-iodoamphetamine (123I-IMP-SPECT) of a patient suffering from Klinefelter's syndrome with various neuropsychiatric symptoms. He was a 30-year-old male, who showed impaired consciousness seizures, auditory hallucination, delusion of reference, delusion of grandeur, psychomotor excitement and intellectual impairment. Although no focal lesion was detected by computed tomography or T1-weighted MRI, T2-weighted MRI provided a heterogeneous high-signal-intensity lesion of the inferior part of the left temporal lobe, which was not enhanced with Gd-DTPA. In addition 123I-IMP-SPECT exhibited focal hypoperfusion in the left temporal lobe on the early images. We suggest that the neuropsychiatric symptoms of this case are associated with the focal organic brain dysfunction which was revealed by MRI and 123I-IMP-SPECT.

This report describes two cases of schizophrenia inpatients with polydipsia, intermittent hyponatremia, and water intoxication. Case 1, a 38 year-old male, developed polydipsia after seven years duration of schizophrenia, with a daily intake of water of more than 10 liters as a result of auditory hallucination suggestion. Nocturnal hyponatremia, agitation and exacerbation of psychosis were noted during admission. After 12 treatments of electroconvulsive therapy, the symptoms of psychosis and polydipsia declined. Case 2, a 42 year-old male, had also been a case of schizophrenia for about twenty years, and developed polydipsia with more than 5 liters of daily water intake in a chronic psychiatric hospital for a period of 5 years schizophrenia. He claimed that he enjoyed the pleasure of drinking water. The symptom of water intoxication had been noted intermittently in the past year, leading to at least two seizures. Finally the patient was transferred to our ward due to agitated mood, self-destructive behavior, consciousness loss, and motor weakness. The clinical features, differential diagnosis and treatment concept of polydipsia and water intoxication were also discussed in context.

Intravenous drip infusions of lidocaine (IDIL; 1-5 mg/kg/h) were performed in ten patients with intractable seizures. The medication was very effective in five patients, whose seizures disappeared immediately after the treatment of IDIL. In four patients, the medication proved to be effective judging from decreased incidence of seizures. In one patient with intractable seizures, the therapy was not effective. In nine patients with the effective medication, five had generalized seizures and four had partial seizures. Side effects were observed in four patients. Two patients had muscle hypotonia, one had visual and auditory hallucination and another had bradycardia. These symptoms completely disappeared after the ceasing of IDIL. Serum concentrations of lidocaine at the appearance of the side effects ranged from 1.8 to 4.7 micrograms/ml, although the toxicity level is more than 5.0 micrograms/ml for arrhythmic adult patients. These findings suggest that the serum toxic level of lidocaine in children is different from that in adults, and that careful observation and appropriate management for the children with lidocaine therapy should be necessary, even though the serum level of lidocaine ranges within the therapeutic level.

Four patients with ictal speech disturbance were studied. Their seizures featured isolated, or series of, brief episodes of fluent paraphasia, paragraphia, and comprehension deficit. These episodes were often induced by language activity. Six patients with ictal paraphasia or paragraphia, as a recurrent habitual seizure, are reported in the literature. All ten cases, including the four cases described here and the six cases reported in the literature, featured patients who uttered meaningless speech fluently or displayed paragraphia. The syllables uttered during seizures contained many neologisms and resembled the neologistic jargon of patients with fluent aphasias of the Wernicke type. Nine patients had clusters or status of brief seizures and four patients had auditory hallucination as an ictal event. The seizures in six patients were easily induced by the use of language. Seizure focus was on the left side in all patients mentioned. The possibility of another type of language-induced seizures than those seen in reading epilepsy or language-induced epilepsy is suggested in which myoclonias of the jaw and face, or upper extremities are the main seizure types.

In several experimental models, status epilepticus (SE) leads to secondary brain hyperexcitability and epileptogenesis. In humans, such phenomena have been rarely demonstrated, particularly in cases of SE involving the neocortical structures. We report a 36 year old woman that presented partial SE in May 1991 involving the right cerebral hemisphere. The patient was then treated in the intensive care unit with artificial ventilation and anesthesia by pentobarbital and clometiazole. MRI showed transient right parietal and temporal posterior cortical hyperintensity. The cause of SE was not determined. Three months later, the patient developed partial complex seizures with aura characterized by vertigo, nausea and auditory hallucination. Ictal video/EEG recording showed a clear right temporal posterior onset of the discharges. We speculate that status epilepticus created the lesions which subsequently caused the focal chronic epilepsy.

The authors previously reported linkage to chromosome 10q22-24 for autosomal dominant partial epilepsy with auditory features. This study describes seizure semiology in the original linkage family in further detail. Auditory hallucinations were most common, but other sensory symptoms (visual, olfactory, vertiginous, and cephalic) were also reported. Autonomic, psychic, and motor symptoms were less common. The clinical semiology points to a lateral temporal seizure origin. Auditory hallucinations, the most striking clinical feature, are useful for identifying new families with this synome.

Hallucinations are defined as sensory phenomena in the absence of external sensory stimuli. Auditory hallucinations have been shown to arise from many different intracranial lesions, but seizures manifesting as musical hallucinations triggered by unruptured intracranial aneurysms are rare. We present a case of persistent, episodic musical hallucinations associated with seizures that led to the discovery of 2 small intracranial aneurysms. Typical electroencephalographic findings for seizure activity were observed but resolved after surgical clipping of the aneurysms. Concomitantly, the patient's hallucinations resolved. The literature on musical hallucinations is reviewed.

A 9-year-old boy diagnosed as having Rasmussen syndrome had congenital IgA deficiency and juvenile alopecia. He developed auditory hallucination and consciousness disturbance with intractable complex partial epileptic status. Anti-glutamate receptor epsilon2 antibodies were detected in his serum and cerebrospinal fluid. He was administered immunomodulatory agents and his seizures were treated with an intravenous anticonvulsant for 2 months. Subsequently, he developed a nephrotic syndrome, which proved to be membranous nephropathy and was treated with cyclophosphamide. Anti-basement membrane antibodies were detected in his serum. The boy died at the age of 14 years, and autopsy revealed diffuse brain atrophy with neuronal loss, infiltration of glial cells in the cerebrum, and loss of Purkinje cells in the cerebellum. A kidney specimen contained many sclerotic glomeruli, indicative of progressive membranous nephropathy. The patient was considered to have multimodal autoimmune disorder producing juvenile alopecia, autoimmune encephalitis, and a membranous nephropathy, based on the congenital IgA deficiency.

Self-injurious behavior (SIB) or self-mutilating behavior (SMB) is rare but can occur in temporal lobe epilepsy. Such a behavior during seizures is not usually recalled by patient. Here is a case with self mutilating behavior in left temporal lobe epilepsy, presented because of its rare manifestation and diagnostic dilemma. A 19 year old unmarried Muslim student presented to emergency with SMB, guilty rumination and a persecutory delusion. The patient was intermittently confused about place and time. In subsequent assessments, he was found harboring death wishes and suicidal ideation. He transiently had auditory hallucination and thought broadcasting. He episodically tried to harm himself by severely biting only his left ring finger. It was difficult to influence him during such episodes. EEG revealed left temporal lobe seizure. Diagnosis of 'Epilepsy and Organic Psychosis' was made. The patient responded well to Antiepileptic and Antipsychotic medications.
