Marijuana is the most commonly used illicit drug in the United States and worldwide. Initiation of use typically occurs during adolescence. The most recent epidemiological data indicate that in the United States, 42% of high school seniors have tried marijuana, 18% have used it in the past 30 days, and 5% use it daily.

There are hundreds of studies that show that pharmacotherapy is used to treat depression in adult and geriatric populations. There are far fewer studies that test the efficacy of psychotherapies and even fewer studies that focus on combined treatment for older patients.

Almost one third of US mental health care costs (approximately $50 billion) go toward the treatment of anxiety disorders. Conventional pharmacological treatments for anxiety are often beneficial but have limited efficacy.

One consequence of the "graying" of the world's population is that psychiatrists, along with all health care professionals, will increasingly be providing services to older adults. In the United States, the first set of people belonging to the baby boom generation turned 60 in 2005, and the number of people older than 60 will soonoutnumber children for the first time in recorded history.

Parkinson disease (PD) is a progressive neurodegenerative disorder affecting 1% of people 65 years and older. The core symptoms include the motor manifestations of tremor, bradykinesia, and rigidity.

Contributing to the problem is the relative unreliability of EEG tracings recorded from patients during the interictal period. Although these tracings can reveal certain abnormalities that are characteristic of epilepsy, such as spikes, they tend to be relatively nonspecific. Interictal spikes, for instance, occur inconsistently; they are present in some persons who do not have epilepsy and absent in others who do.

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.

Poetry of the Times

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.
