We investigated possible causative factors for the high epileptic suicide rate by reviewing the cases of 22 patients with idiopathic epilepsy found among 711 patients hospitalized for a suicide attempt by overdose. Suicide attempts occurred with increased seizure activity in one epileptic; otherwise, no relationships were found with seizure-related variables. When matched by age, sex, and race with 44 nonepileptic controls from the same population, the epileptics had more borderline personality disorders with multiple impulsive suicide attempts (45.5% vs 13.6%), more psychotic disturbances, including command hallucinations (31.8% vs 9.1%), fewer adjustment disorders (18.2% vs 45.5%), and a comparable frequency of depression (13.6% vs 25%). We conclude that suicide attempts in epileptics are primarily associated with interictal psychopathologic factors, such as borderline personality disorder and psychosis, rather than with specific psychosocial stressors, seizure variables, or anticonvulsant medications.

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.

Central venous catheters are sometimes the cause of life-threatening complications. In two patients with underlying psychiatric disorders we observed an embolism as a result of catheter fragments. The first patient was a 30-year-old woman with a borderline personality disorder and several previous episodes of self-mutilation, psychogenic seizures and disturbances of consciousness. She cut her central venous line positioned in the external jugular vein when she was unattended. The intravasal fragment dislocated into the right ventricle and had to be removed by a forceps used for myocardial biopsies. The second patients was a 34-year-old mentally retarded male with a history of psychomotoric and grand mal seizures who suffered from a prolonged disturbance of consciousness with uncontrolled motor activity after four grand mal seizures. Despite physical restraint, the tip of his central venous catheter inserted through the subclavian vein broke and embolized in the right atrium. The embolus was removed by thoracotomy. To avoid these complications central venous lines should be used only when critically needed in uncooperative patients or those who display disturbance of consciousness and uncontrolled motor activity.

Psychogenic pain, disturbances of gait and stance, sensory symptoms, dizziness, and psychogenic seizures have been found to be the most common conversion symptoms in neurology clinics. A retrospective analysis of 18 patients suffering from pseudoseizure "status" is presented in this study. All of the patients fulfilled the DSM-III-R criteria of conversion disorder. However, 5 of them had concomitant major depression, 6 suffered from bulimia nervosa, and 7 met the criteria for substance abuse. On Axis II, 10 cases of borderline personality disorder, 2 cases of antisocial personality disorder, and 3 cases of histrionic personality disorder were diagnosed. The majority of the patients had attempted suicide and other forms of self-destructive behavior. The findings suggest that patients with pseudoseizure "status" suffer from severe affective imbalances and disturbed impulse control.

Prematurity, intrauterine infection and perinatal brain injury have been reported to be significant risk factors of cerebral palsy (CP). We examined the perinatal predictors of cerebral palsy and delayed development (DD) in 184 high risk infants. Thirty-five infants were diagnosed as cerebral palsy and delayed development at 12 months corrected age. Antenatal, intrapartum, and neonatal factors were prospectively evaluated in 2 groups of high risk infants compared with controls; Group A (n = 79), infants weighing less than 2,000 g; Group B (n = 43), infants weighing 2,000 g or more. In univariate analysis, there were no significant antenatal and intrapartum factors associated with cerebral palsy and delayed development in either group. We found that significant postnatal risk factors of CP in group A included sepsis (p = 0.008), BPD (bronchopulmonary dysplasia) (p = 0.028), IVH (intraventricular hemorrhage) (p = 0.042), ventriculomegaly (VM) (p = 0.001) and a longer duration of mechanical ventilation (p = 0.001); while in group B, sepsis (p = 0.047) and neonatal seizure (p = 0.027) were significant risk factors. In multivariate analysis, sepsis in group B was a moderate risk factor of CP (OR (odds ratio) 1.47; 95% CI (confidence interval) 1.02-2.13). In conclusion, neonatal sepsis may contribute to the development of cerebral palsy and delayed development. We suggest that high risk infants who have sepsis should be carefully followed for cerebral palsy and delayed development. The prevention of cerebral palsy may be feasible by decreasing neonatal risk factors such as sepsis during the neonatal period.

The history of antipsychotic medications begins in the 1950s with chlorpromazine, developed originally as an antihistamine but found to be an aid in the reduction of symptoms of delusions and hallucinations. This phenothiazine derivative was followed by numerous others in the same class (e.g., thioridazine) and then by antipsychotics in other classes (e.g., the popular haloperidol of the butyrophenone class). This group of medications is associated with a number of unpleasant side effects and complications. These included extrapyramidal symptoms (EPS), orthostatic hypotension, hyperprolactinemia and last, but certainly not least, tardive dyskinesia (TD). As a consequence, other alternative antipsychotics were developed in which D(2) blockade effect generally associated with EPS and TD was offset by 5-HT(2) antagonism. The first of this class was clozapine; however, it is associated with agranulocytopenia of sudden onset as well as seizure induction. However, olanzapine, a close structural relative, was soon synthesised for treatment of psychosis and particularly schizophrenia (Zyprexatrade mark, Eli Lilly). It was released in the US in November 1996 with FDA approval for that indication. However, antipsychotics have always been used for other psychiatric disorders, aside from schizophrenia. This includes, in particular, mania, where chlorpromazine use predated lithium as an effective treatment. Other uses for antipsychotics have included other mood disorders, dementia, childhood disorders and personality problems. Here, information on the application of olanzapine to non-schizophrenic disorders is reviewed. Despite the fact that the research post-dates FDA approval in 1996, there was already sufficient evidence for olanzapine's effectiveness in acute mania to obtain approval from the US FDA in March 2000. Other research supports its use as adjunctive therapy in depressive disorders. Phase IV studies and case reports have found limited support for olanzapine's use in a variety of other psychiatric disorders, behavioural disorders of dementia (including Alzheimer's disease), pervasive developmental disorder of childhood, obsessive-compulsive disorder and borderline personality disorder. In each of these latter diagnoses, double-blind studies are either underway or are planned to establish efficacy.

The clinical presentation of borderline personality disorder (BPD) bears a striking resemblance to the behavioral alterations associated with temporal lobe epilepsy. Using the Limbic System Checklist-33, we found that BPD subjects reported more symptoms associated with partial seizures than did control subjects. BPD patients also exhibited deficits on immediate and delayed recall of the Rey-Osterrieth Complex Figure and produced distorted drawings of the Rey Figure. Their degree of impairment correlated with their report of temporolimbic symptoms. Results are consistent with the proposal that temporolimbic dysfunction underlies the behavioral dyscontrol and affective dysregulation present in BPD.

Zolpidem is a sedative and hypnotic drug belonging to imidazopyridine family. Zolpidem facilitates GABAA function more selectively than benzodiazepines, and produces a selective hypnotic effect. In comparison with benzodiazepines this mechanism could be reduce liability to induce dependence. Recently, some cases of zolpidem abuse and dependence have been published. The Authors report 2 cases of addiction to high dose of zolpidem and compare them with others described in the literature. Both patients had been reknown drug addicts before their first prescription of zolpidem and a borderline personality disorder was diagnosed. The patients rapidly developed over consumption and dependence of the molecule, when taking doses as high as 240 and 400 mg daily. To get zolpidem, one patient falsifies prescriptions. They don't suffer from the sedative effects while searching for anxiolytic and stimulating effects. They were also dysarthric, confused, high energy for mental and physical activity. The cases of zolpidem abuse and dependence in the literature describe these symptoms and others such as losing sense of orientation in time and space, amnesia and visual hallucinations. The most typical withdrawal symptom is high levels of anxiety. Moreover, one patient presents an epileptic seizure whereas the other display a severe psychiatric complication such a psychosis. In the literature, withdrawal was accompanied by confusion, suicidal ideas, nausea, vomiting, sweat, tremors, tachycardia and insomnia rebound. The epileptic seizures are described but acute psychosis complication is rare. Pharmacological hypotheses are described. The effects of zolpidem on GABAA receptor gene expression are consistent with the reduced tolerance liability of this drug as well as with other ability to induce both physical dependence and withdrawal syndrome. Through the review of the literature, the Authors noted that 50% of the cases of dependence on zolpidem are drug addicts, therefore concluding that drug addicts are more likely to become dependent on zolpidem.

The tragic life of Vincent van Gogh is summarized, emphasizing his early departure from formal education, failure as a successful salesman in the art world, attempt at religious studies, difficulty with female and family relationships, return to the art world, and tendencies toward extremes of poor nutrition or near self-starvation and excessive drinking and smoking. In Paris he joined the Impressionists, but drank very heavily both absinthe and cognac. Southward he went to Arles and was joined by Paul Gauguin, with whom he had major personality problems, causing van Gogh to cut off part of his left ear. He experienced paranoid ideation and confinement in mental institutions in Arles, and then returned to Paris and onto Auvers-sur-Oise, where he committed suicide at age 37. Possible physical diagnoses include glaucoma, Meniere's disease, acute intermittent porphyria, and chronic lead poisoning, but these diagnoses seem unlikely. Possible psychiatric diagnoses include borderline personality disorder, anxiety-depressive disorder with episodes of depression and hypomania, and also paranoid schizophrenia. Van Gogh did not have spontaneous seizures and, therefore, did not have epilepsy. Before he began to drink heavily, when he was near starvation, he had "fainting fits," and after drinking, especially absinthe, a convulsant drug, he continued to have similar attacks. His episodes of unconsciousness can be well explained by chronic malnutrition and alcohol abuse, only possibly exacerbated by drinking large quantities of absinthe. Although van Gogh is an excellent example of the Geschwind syndrome, at times associated with temporal lobe epilepsy, this fact does not establish such an epilepsy. Thus, the syndrome is an orphan without the parent condition.

Valproate (VPA) is a well-established anticonvulsant drug that has found increasing use as a psychotherapeutic agent. The drug is currently used in the management of bipolar, depressive, anxiety, and psychotic disorders; alcohol withdrawal and dependence; agitation associated with dementia; and borderline personality disorder. Despite such widespread use, studies focusing on the concentration-response relationship of VPA in psychiatry are limited. This article examines the rationale for therapeutic monitoring of VPA in psychiatric disorders and reviews reports of VPA concentrations measured during efficacy studies of this drug in psychiatry. Most studies have been open-labeled and uncontrolled, and have not placed the determination of a target concentration range as a primary objective. Furthermore, most studies have used the therapeutic range (50-100 mg/L) for seizure disorders to guide dosage in the psychiatric disorders, although study outcomes have suggested the need to redefine a threshold concentration in the different psychiatric conditions. With the increasing popularity of VPA as a psychotropic agent, it is clear that further investigation of the plasma concentration range associated with efficacy in psychiatric conditions is warranted.
