We evaluated central nervous system and psychiatric involvement in a clinical sample of 32 patients with systemic sclerosis (SSc) (scleroderma). All patients underwent clinical neurological examination. Electroencephalography (EEG) and visual evoked potentials (VEPs) were also recorded. Prominent central nervous system (CNS) or psychiatric symptoms were present in 5 patients (16%), including encephalopathy, psychosis, anxiety disorder, grand mal seizures and transient ischemic attack. In addition, abnormal VEPs were recorded from 5/32 patients (16%), suggesting optic neuropathy. EEGs were mainly normal or showed only slight, nonspecific changes. Primary CNS involvement in scleroderma, however, could not be shown in any of the 5 cases with neuropsychiatric symptoms. Our results suggest that neuropsychiatric symptoms in SSc are, if not coincidental, indirectly caused by internal organ involvement of SSc or by possible overlapping connective tissue diseases. On the other hand, optic neuropathy might be a primary complication of SSc.

The adverse stresses and injuries associated with epileptic seizures are prevented routinely when programmed, controlled grand mal seizures are administered. According to the described concepts of clinical benefit, symptoms of brain illnesses that are without substantial neuronal deterioration, but that have a sense of neurotransmitter dysregulation, are candidates for mitigation by administration of programmed seizures. Such symptoms include delirium, dementia, neuroleptic malignant syndrome, movement disorder, psychosis, and depression. Prior to recommending cortical excision for management of offtial complex epilepsy, a course of programmed seizures should be considered routinely.

A case of psychosis accompanied with variable symptoms induced by chronic volatile solvent inhalation is reported in this study. The patient was a 27-year-old male who had abused volatile solvents for 15 years, and was sent to the hospital because of a tonic-clonic seizure. Severe psychomotor excitement was observed on the first day and the 7th day after admission. After 10 days of admission, we observed visual transformation and hyperthermia, which suggested acute toxic symptoms due to a volatile solvent. Furthermore, symptoms such as incoherence, delusions of persecution, and catalepsy were also observed in this case. There have been few reports of multiple neurological and mental symptoms appearing in cases of volatile solvent psychosis. Although we sometimes experience cases of solvent abuse with acute mental symptoms and recurrent excitement after sedation, such symptoms are not always observed because of flashback in the strict sense. Therefore, careful early treatment should be employed to prevent 'secondary excitement'.

Three patients who presented with grand mal seizures and an associated behavioral disorder were recognized as suffering from a severe butalbital withdrawal syndrome. All were migraineurs who had become dependent on barbiturates. We propose that the occurrence of seizures, psychotic behavior, or a recent personality change should be considered clues to possible barbiturate abuse in patients with migraine.

Ramsay Hunt syndrome (RHS) is a rare condition within the progressive myoclonic epilepsies syndrome (PME), with a triad of action myoclonus, grand mal seizure and severe cerebellar ataxia. There are few reports about the psychiatric disturbances associated with PME or RHS. The present study examines the evidence that RHS may accompany an organic mental syndrome, ethanol's effective suppression of myoclonus, and the possible resultant problem of alcohol dependence in RHS patients. Two brothers with the previous long-standing diagnosis of RHS and their mental symptoms of persecutory delusion and depression are reported, as well as the additional problem of alcohol dependence in one of them. The cerebellar dysfunction found in RHS may be associated with an underlying organic condition. Determination of the relationship between cerebellar dysfunction and psychosis in RHS will require further study. Although the mechanism of the suppression of myoclonus by alcohol remains unclear, patients should be allowed to drink socially, and alcohol consumption should not be totally prohibited. However, effective treatment of the problems of alcohol tolerance, abuse, or dependence requires the cooperation of both neurologists and psychiatrists.

The association of epilepsy and psychosis is studied. Among the 500 patients of epilepsy evaluated, there were 12 patients, 8 males and 4 females with epilepsy-related psychosis. Their average age was 38 years. The interval between the age of onset of epilepsy and psychotic features was 9 years. Complex partial seizures were present in 7 patients and primary generalized tonic-clonic seizure was present in 1 patient. Four patients had post-ictal psychosis, 7 had acute interictal psychosis and 1 patient had chronic psychosis. The inter-ictal and chronic psychoses were schizophreniform whereas the post-ictal psychoses were not. EEG showed a temporal focus in 7 patients with complex partial seizures and an extra-temporal focus was identified in 4 out of the other 5 patients. Imaging (CT scan/MRI) revealed abnormalities in 10 patients. This study attempts to define the characteristics of psychoses occurring in epileptics.

Electroconvulsive therapy (ECT) is the fastest and most effective treatment for severe or treatment-resistant affective and psychotic disorders. Its therapeutic effect is obtained through a generalized tonic-clonic seizure of adequate duration. Several factors (older age, male gender, and the sessions of ECT themselves) increase seizure threshold and reduce seizure time. In our work, sleep deprivation was used as a strategy to enhance the ECT seizure. A matched sample design was conducted on the basis of the following variables: gender, age range, and seizure threshold. After the first ECT, when the initial seizure threshold was measured, subjects were assigned to ECT (electroconvulsive therapy) or SD+ECT (sleep deprivation + electroconvulsive therapy). Changes in the variable of seizure threshold were studied in both groups during the treatment course. A nonparametric analysis was implemented for 2 independent groups. During the treatment course, the SD+ECT group showed a decreased seizure threshold, from 190.4 mC in the first ECT session to 176.4 mC in the last ECT session, whereas the ECT group showed an increased seizure threshold, increasing from 190.4 mC to 321.91 mC. Sleep deprivation is an effective and safe technique used to lower the seizure threshold of ECT and to obtain an adequate seizure time without increasing the energy applied.

A 55-year-old man with congenital hemiparesis of the right side, three episodes of generalised tonic-clonic seizure at 16 years of age, and two episodes of severe depression and two episodes of hypomania in the past, presented with severe depression with psychotic symptoms. Computed tomography of the brain showed a grey matter-lined cerebrospinal fluid-filled cleft in the left cerebral hemisphere, involving the temporoparietal region. He was diagnosed to have bipolar II disorder, and was currently severely depressed with psychotic symptoms and schizencephaly. He improved with sodium valproate 1,000 mg/day, quetiapine 450 mg/day and escitalopram 20 mg/day after three weeks without any emergent side effects, and was maintaining well at three months follow-up. Although uncommon, schizencephaly may be considered as one of the differentials in cases of bipolar disorder along with congenital hemiparesis, mental retardation and/or seizures; and neuroimaging should be done to confirm the diagnosis.

Atypical antipsychotics are known to be associated with electroencephalogram abnormalities. Olanzapine can lower seizure threshold and induce epileptiform discharges. However in patients on olanzapine for the treatment of a primary psychiatric disorder, clinical seizure is a rare occurrence. We report the case of a 25-year-old man with a diagnosis of paranoid schizophrenia with obsessive-compulsive disorder of 8 years' duration who developed new-onset generalized tonic-clonic seizure with exposure to olanzapine. Electroencephalogram showed epileptiform discharges; results of computed tomographic scan and metabolic investigations were normal. His antipsychotic was changed to haloperidol, and the patient showed a significant improvement in psychotic symptoms with no recurrence of seizures and did not require anticonvulsant therapy. Olanzapine has a profile similar to that of clozapine and shares its seizure-inducing potential. Typical antipsychotics such as haloperidol might be a safer option for such patients.

Postictal psychoses are common comorbid conditions of temporal lobe epilepsy and are reported to be characterized by affective changes. However, postictal psychoses are rare among patients with idiopathic generalized epilepsy, and the causal relationship between postictal psychoses and idiopathic generalized epilepsy is unknown. Here, we report the case of a man who had idiopathic generalized epilepsy and experienced 4 episodes of schizophrenia-like interictal psychosis before the age of 41 years. At the age of 56 years, he experienced a generalized tonic-clonic seizure for the first time in 15 years and developed psychotic symptoms on the next day. Notably, in addition to the schizophrenia-like symptoms, the patient experienced mania-like symptoms such as elated mood, grandiose delusions, agitation, and pressured speech during the last psychotic episode in the postictal period. It was suspected that postictal neuronal processes and a predisposition to endogenous psychosis both contributed to the psychopathology of this episode.
