A review of the worldwide published literature was conducted to assess the efficacy and safety of alprazolam for the treatment of anxiety disorders, panic disorder, and depression in comparison with those of other active drugs (including other benzodiazepines and antidepressant medications). In all, a total of 8878 patients participated in the 84 active-drug-controlled studies that were reviewed: 3574 were treated with alprazolam, 3666 were treated with another active drug, and 1638 were treated with placebo. Two general findings emerged: (1) Alprazolam demonstrates efficacy for the treatment of anxiety disorders, panic disorder, and depression in the large majority of studies; for these illnesses, it appeared equal in efficacy to the active agents with which it was compared. (2) Medical events, such as depression, suicidality, hostility/aggression, mania/psychosis, abuse, withdrawal reactions, and seizures, were reported infrequently or not at all for alprazolam and the comparator drugs; there were no marked differences between drug classes in the frequencies of these events.

Since Cullen coined the term "neurosis" in the 18th century, medical investigators have searched the neural substrates of conditions we now classify as anxiety disorders. Harper and Roth in 1962 hypothesized that the temporal lobes might represent one such substrate for phobic-anxious patients with depersonalization-derealization (DD); the association between the presumed temporal lobe feature and phobic anxiety was so compelling that Roth (in 1959) described the condition as "phobic-anxiety-depersonalization" syndrome. Introduced into our current nosology as panic disorder-agoraphobia (PDA), this seemingly neuropsychiatric condition is nonetheless distinct from complex partial epilepsy (CPE), from which it is conventionally differentiated through clinical and anamnestic evaluation. Yet increasingly there are clinical-and laboratory-hints of certain overlap between manifestations of the two disorders, hitherto based largely on evaluation of psychosensorial phenomena in PDA or affective phenomena in CPE. We located only one systematic study that monitored 24-hour electroencephalogram (EEG) abnormalities in PDA. Finally, recent epidemiologic data suggest a significantly greater than chance association between PDA and a history of seizures. To further explore these intriguing links, the present study directly compared a group of 91 PDA outpatients with a group of 41 CPE outpatients with respect to DD and other psychosensorial symptoms. The broad similarities discovered between psychosensorial and related phenomena provide further support for the hypothesis that there may be a common neurophysiological substrate linking CPE phenomena with PDA.

The goal of this paper is to draw conclusions about the usefulness of the standard EEG in psychiatry. In general, two thirds of psychiatric referrals for an EEG are expected to provide useful information. The emphasis in schizophrenia is placed on left-sided abnormalities, especially on the left temporal area. In mood disorders the emphasis is on right-sided foci, in addition to the controversial 6/sec spike and wave complexes, small sharp spikes and positive spikes. In the acute stage of alcoholism, a relationship is seen between the degree of intoxication and the amount of slow activity, while in the chronic stage an increase in slow activity is seen, but another change is fast activity on the temporal areas. During withdrawal a low seizure threshold can be seen as irregular bilateral spike and wave complexes. During abstinence 2-4 yr may be required before slow wave sleep is normal in all regards. Among the organic mental syndromes, delirium shows slow activity, except in delirium tremens, which often is associated with a normal record with fast activity. In dementia the prevalence of EEG abnormalities is related to the degree of impairment. After five sessions of ECT diffuse slow waves are often seen. In other conditions, among developmental disorders about one half of autistic children show abnormalities and epileptiform activity is not uncommon. Mild nonspecific abnormalities are seen in about 40% of dyslexics and also in behavior disorders. Anxiety disorders include anorexia nervosa, showing abnormal background activity related to the effect of starvation on cerebral metabolism. In panic attacks paroxysmal activity can be seen. In borderline personality positive spikes have been (again) associated with impulsivity and 6/sec spike and wave complexes with interpersonal problems. Of the drugs of abuse psilocybin and phencyclidine are often associated with generalized epileptiform patterns and with marijuana the alpha shows a decreased frequency with increased amplitude. Typically, an increase in slow activity is seen with psychotropic drugs if there is a change in the level of awareness. Finally, distinctive personality traits are, at times, seen in temporal lobe epilepsy and the phenomenon of "forced normalization" may appear when seizures stop and psychotic symptoms appear.

Clinicians must consider the psychiatric issues relevant to patients undergoing neurosurgical procedures for epilepsy. Obtaining the patient's psychiatric history can facilitate stabilizing the patient's condition before operative intervention. Preoperatively, depressive and anxiety disorders are the most common psychiatric conditions diagnosed in candidates for surgical treatment of epilepsy. Although psychotic disorders occur infrequently, they demand attention because symptoms may interfere with patient compliance with follow-up care. Patients with chronic psychotic symptoms who have ongoing seizures postoperatively and bilateral seizure foci are at higher risk for a poor outcome and postoperative psychosis. When psychiatric disorders are present, surgical management is not contraindicated, but preoperative psychiatric intervention may be warranted. Most patients have a favorable outcome with the elimination of seizures, which simplifies the subsequent treatment of a psychiatric disorder.

Children with asthma frequently have significant anxiety and depression that interfere with treatment outcome. Although the use of antidepressants may be helpful, in the one published study of antidepressant use in pediatric asthma, significant side effects necessitated discontinuance; these side effects were increased motor activity, impulsive behavior, insomnia, postural hypotension, premature auricular contractions, diastolic hypertension, and generalized seizure. The objective of this retrospective chart review was to examine whether antidepressants could be tolerated and administered safely to children on asthma medications. Forty pediatric inpatients (mean age 13.3 years, range 7-19) with varying levels of asthma severity (5 mild, 11 moderate, 24 severe) and an average duration of asthma treatment of 10.0 years were administered antidepressants while also taking an average of 5 medications for asthma (range 2-7). Ten of the patients had an additional comorbid medical diagnosis. There were 17 children diagnosed with a primary affective disorder; 7 with a primary anxiety disorder; and 16 with both an affective and anxiety disorder. Thirty-six children ultimately were continued on an antidepressant: 13 on desipramine, 9 on nortriptyline, 6 on imipramine, 4 on fluoxetine, 3 on bupropion, and 1 on sertraline. Significant cardiovascular side effects (tachycardia, hypertension, and postural hypotension) occurred in 4 subjects on tricyclic antidepressants (TCAs) and 1 subject on a non-TCA (fluoxetine); 3 of these subjects were able to continue treatment with an antidepressant. Two subjects were taken off antidepressants because of hypomanic symptoms (increased motor activity, mood lability, impulsive behavior, and insomnia). No medications were discontinued because of electrocardiogram changes, arrhythmias, or seizures. Doses of TCAs were comparable to those in previous studies, but the asthma medications differed. Discussion of current anti-asthmatic medications and potential for interactions with antidepressants is included.

A retrospective study compared the course of alcohol withdrawal, including delirium tremens, in women and men hospitalized in the Nowowiejski Hospital in Warsaw from 1973 to 1987. Medical records pertaining to 1179 patients were analyzed; 13.8% of these patients were women and 86.2% were men. The study showed that women began intensive alcohol drinking later than men (p < 0.0001), but the period between the onset of alcohol abuse and the first occurrence of alcohol withdrawal was shorter in women than in men (p < 0.0001). In the period of heavy drinking before hospitalization, women consumed significantly less alcohol then men (p < 0.0001); moreover, women drank nonbeverage alcohol less frequently than men (p < 0.05). Women were hospitalized substantially longer than men (p < 0.0001), whereas the duration of alcohol withdrawal symptoms at the time of hospitalization was comparable in both groups. Withdrawal seizures were significantly more frequent among men than among women (p < 0.001). Significant differences in the patients' somatic conditions were not noted between the groups, with the exception of anemia and decreased potassium concentration, which were more frequently observed in women (both p < 0.0001), and of increased concentration of ALT and hypoproteinemia, which were more frequent in men (respectively, p < 0.05 and p < 0.01). Co-existing personality disorders, depressive disorders, and anxiety disorders--as well as abuse of benzodiazepines and barbiturates--were more frequently observed in women (p < 0.0001). The period between the first hospitalization due to alcohol withdrawal and the time of death was significantly shorter in men than in women (p < 0.05). The results point to differences in the conditions and the course of alcohol dependence and alcohol withdrawal between women and men.

Buspirone is a novel anxiolytic agent that is commonly used in the treatment of generalized anxiety disorder. Many studies have found it to be equal in efficacy to the benzodiazepines in the treatment of this illness. Its use has gained favor over the past few years because of its relatively mild and tolerable side-effect profile. The authors report a case of buspirone overdose that resulted in a generalized tonic clonic seizure approximately 36 hours after ingestion. Although there have been no previous cases of seizure induction by buspirone in humans, there are animal models of this phenomenon. The authors describe the case, review the literature regarding buspirone overdose and toxicity, and discuss treatment recommendations.

Children with epilepsy have more behavioral and cognitive problems than children with other chronic illnesses and children in the general population. Risk factors are multiple, probably involving a combination of neurological, seizure, family, and child variables. Problems with attention and symptoms of depression occur frequently but may be unrecognized. Anxiety disorders and psychoses are less common. There are very few studies defining most effective therapies for behavioral problems in children with epilepsy. Education, group psychotherapy, and psychopharmacology have been used with success.

Autism is a neurobiological disorder. The core clinical features of autism include impairment in social interaction, impairments in verbal and nonverbal communication, and restricted, repetitive, and stereotyped patterns of behavior, interests, and activities. Autism often has coexisting neuropsychiatric disorders, including seizure disorders, attention deficit hyperactivity disorder, affective disorders, anxiety disorder, obsessive-compulsive disorder, and Tourette disorder. No etiology-based treatment modality has been developed to cure individuals with autism. However, comprehensive intervention, including parental counseling, behavior modification, special education in a highly structured environment, sensory integration training, speech therapy, social skill training, and medication, has demonstrated significant treatment effects in many individuals with autism. Findings from preliminary studies of major neurotransmitters and other neurochemical agents strongly suggest that neurochemical factors play a major role in autism. The findings also provide the rationale for psychopharmacotherapy in individuals with autism. This article reviews studies of neurochemical systems and related psychopharmacological research in autism and related neuropsychiatric disorders. Clinical indications for pharmacotherapy are described, and uses of various medications are suggested. This article also discusses new avenues of investigation that may lead to the development of more effective medication treatments in persons with autism.

The authors studied six children with repetitive psychogenic seizures severe enough to mimic status epilepticus. All received IV antiepileptic drugs in an emergency setting. Most had a family history of epilepsy. Affective and anxiety disorders predominated as comorbid psychiatric diagnoses. Acutely stressful situations precipitated all episodes of nonepileptic status epilepticus. With aggressive psychotherapeutic intervention and pharmacologic treatment of their underlying psychiatric diagnosis, the patients improved.
