Many persons with epilepsy have comorbid conditions that are treated with concomitant medications. However, patients for whom first-generation antiepileptic drugs (AEDs) are prescribed have been shown to be at high risk for drug interactions with medications that involve the cytochrome P-450 pathway, specifically antipsychotics, contraceptives, tricyclic antidepressants (TCAs), calcium channel blockers, and warfarin.

A 35-year-old right-handed white man presented with an 8-day history of left leg weakness and difficulty in walking. A day after the onset of symptoms, he self-medicated with oral prednisolone for 1 day and tapered the medication over 6 days. The leg weakness improved over the course of treatment but worsened afterward. His medical history is significant for multiple sclerosis (MS) and restless legs syndrome. He had 1 previous exacerbation of MS 3 years ago.

Vision Restoration Therapy (VRT) is an FDA-cleared device for treatment of visual field defects caused by stroke or traumatic brain injury. The therapy works by stimulating the brain to form new connections, according to NovaVision, the device's manufacturer. But critics maintain that VRT is nothing more than a pricey way to promote saccadic eye movement.

In the early 1990s, researchers began looking at potassium channel openers for seizure control. Over the past 10 years, in vitro research and animal studies demonstrated that potassium channel openers could control seizure activity in a dose-dependent way. Clinical trials are now confirming these findings.

The degree of asphyxia is best ascertained by measuring the amount of fetal acidosis determined by umbilical arterial blood. An umbilical arterial pH of less than 7.0 is seen in about 0.3% of deliveries.1 It indicates a severity of acidosis that places the fetus at risk for permanent neurological damage because of asphyxia. However, the outcome of infants with umbilical cord pH of less than 7.0 who required neonatal intensive care is relatively good. Eighty-one percent can be expected have a normal examination at discharge.

Since April 2006, I have traveled 3 times to the Central Asian Republic of Tajikistan to work with migrants on the risk of HIV/AIDS. According to the United States Agency for International Development, Central Asia has the fastest growth rate of HIV/ AIDS in the world.

Voluntary informed consent is, with rare exceptions, a necessary, albeit not sufficient, defining precondition of ethical clinical treatment, and it is essential for enrollment in clinical research trials.

The clinical management of patients with psychopathy and other psychopathic disorders presents a vexing challenge for mental health professionals. The issues of hospital treatment and civil commitment can be especially confusing.

Depression is primarily a mood disorder, but it can also be viewed as a cognitive disorder for many older adults.

A new strategy that normalizes neurotransmitter deficits common in withdrawal from long-term cocaine use may reduce cocaine-seeking behaviors.

The articles in this Special Report, although far from comprehensive, address an intriguing sample of the many key topics in child and adolescent psychiatry today.

The FDA is considering changes to the Patient Medication Guides (MedGuides), which must now accompany about 65 drugs, including those in 2 major classes, one of which is antidepressants. MedGuides provide information about potential adverse reactions and are considered a warning of sorts.

How time flies! It has been more than a year since my last column, when I staked my claim in psychiatry. I planned to eschew the medical rat race and find my own little piece of medicine as it used to be, when doctors were doctors, nurses were nurses, and insurance salespeople were . . . salespeople. Should one read anything into the long delay between that column and this one? Absolutely! But I'll get to that.

There are moments in therapy that seem to have a special, illuminative quality; something important is suddenly revealed. Such moments may come as the result of deliberate observational and interventional processes or may emerge from the therapist's unconscious.

According to the National Institute on Drug Abuse, of all the illicit substances, marijuana is the most commonly abused among adolescents and young adults, and abuse during adolescence increases the likelihood of dependency in adulthood.

Is neuromyelitis optica (nmo) igg autoantibody unique to NMO or is it expressed in multiple sclerosis (MS) as well? Recent studies have confirmed the autoantibody’s specificity and are shedding more light on how NMO IgG's autoantigen, the water channel aquaporin-4 (AQP4), uniquely behaves in NMO and MS.

I was Dr George Engel's assistant and associate for 14 years. His biopsychosocial model was a conceptual effort designed to get beyond the reductionistic biomedical model that still prevails. In his letter, Dr Victor Schwartz reads Dr Engel much more closely and to the point than does Dr Waterman "Biopsychosocial Model: Helpful or Hindering?" Psychiatric Times, May 2007).

Although the Washington Report used the term "postabortion depression," this is a term to which the APA objected. There is no credible scientific evidence for such a diagnostic category or for a causal relationship between abortion and mental illness.

Near the top of your wish list might be a way to selectively turn on or off individual wires in the black box, because it would allow you to falsify causal linkages, associating observable changes in robotic behavior with your manipulations.

All of us have heard the phrase "between a rock and a hard place," and many of us have been in the situation that the idiom describes. However, few of us (other than English professors) likely know the origin of the saying and even fewer of us know how it applies to clinical psychiatry. Delving into these seemingly unrelated queries will be the subject of this month's column.

Early relapse is a limiting defect in electroconvulsive therapy (ECT). Although more than 80% of patients with a severe depressive illness who complete an acute course of ECT are relieved within three weeks, up to 60% relapse within six months, despite continuation treatments with antidepressant medications.1,2 In a large, government-supported, collaborative study led by the Columbia University Consortium (CUC), patients with unipolar major depression that had failed to respond to multiple trials of medications were treated with ECT to clinical remission and then randomly assigned to one of three continuation treatments--placebo, nortriptyline (Aventyl, Pamelor) alone, or the combination of nortriptyline and lithium (Eskalith, Lithobid). The patients were monitored for adequacy of blood levels.1 Within the six-month follow-up period, 84% of patients treated with placebo, 60% of patients treated with nortriptyline, and 39% of patients treated with the combination medications had relapsed.

It is not known what makes children vulnerable to the development of psychogenic nonepileptic seizures. To date, there are no research studies available on the epidemiological, medical, or genetic risk factors for childhood PNES.

Since its introduction in DSM-III in 1980, attention-deficit/ hyperactivity disorder (ADHD) has proved to be a developmental disorder with many causes and complex behavioral, cognitive, and emotional manifestations that can impair academic functioning, occupational achievement, social relationships, and self-esteem.

Bone mineral density (BMD) was reduced at a greater rate in older women when they had symptoms of depression, according to one recent report from the Study of Osteoporotic Fractures Research Group, while another report implicated treatment with SSRI antidepressants.

Suicide is the third leading cause of death in younger (10- to 14-year-old) adolescents in the United States and the leading cause of death in this age group in other countries, including China, Sweden, Ireland, Australia, and New Zealand.
