Office management of attention-deficit/hyperactivity disorder (ADHD) differs in many important ways from ADHD management conducted in a research environment. In clinical trials, treatments and eligible patients are selected in advance by committees, patients are randomized to different management strategies, and both clinicians and pa tients are blinded to the treatments.

The setting of a fast-paced emergency department (ED) or psychiatric emergency service makes it especially difficult to sensitively elicit and address an individual patient's needs and concerns. When considering the myriad differences in culture that come into play between a patient and a psychiatrist or other mental health care clinician, optimal diagnosis and treatment can be even more challenging, as the cases described here illustrate. The important influence of culture cannot be stressed enough. Taking the time to understand "where the patient is coming from" can prevent an already stressful, highly emotionally charged situation from becoming even more convoluted.

In 1931, Gananath Sen and Kartick Chandra Bose reported on the use of an alkaloid extract from the Rauwolfia serpentina plant in the treatment of hypertension and "insanity with violent maniacal symptoms." They noted that dosages "of 20 to 30 grains of the powder twice daily produce not only a hypnotic effect but also a reduction of blood pressure and violent symptoms

Most physicians make at least some use of the placebo effect to enhance treatments, whether they realize it or not. This article examines the extent of the placebo effect in patients with psychiatric illness, and reviews what is known about how placebos work.

Schizophrenia poses a challenge for diagnosis and treatment at least in part because it remains a syndromal diagnosis without clearly understood neuropathological bases or treatments with clearly understood mechanisms of action. Neuroimaging research promises to advance understanding of the unique pathological processes that contribute to this syndrome, and to foster both better appreciation of how current treatments work, and how future treatments should be developed.

Although several clinical studies suggest that cognitive impairments in schizophrenia are associated with reduced stimulation of dopamine receptors in the prefrontal cortex, mounting evidence suggests that other monoaminergic neurotransmitter systems may also be involved. We provide an overview of neurotransmitters that hold promise as therapeutic interventions for the cognitive deficit in schizophrenia.

If done properly, the assessment of alcohol and substance use disorders in the emergency department (ED) or psychiatric emergency service can be the first step toward recovery. A proper assessment, however, can be extremely taxing for both the clinician and the patient. This article offers a paradigm for performing a rapid and comprehensive evaluation in the ED of medically stable adults with alcohol and substance use disorders.

There has been increasing interest in the overlap between attention-deficit/hyperactivity disorder and substance use disorders. Pharmacotherapeutic treatment of ADHD in children reduces the risk for later SUD in adolescence and adulthood. In contrast, medication treatment of substance-abusing adolescents with ADHD does not reduce the SUD. Diagnostic and treatment strategies for adults with ADHD plus SUDs are discussed.

Impulsive behaviors play an important role in both bipolar and substance abuse disorders. However, results of studies investigating this link are often ambiguous, in part, due to the multidimensional nature of the impulsivity construct and the fact that many studies use a single measurement technique. We describe a model of impulsivity characterized by three components: response initiation, response inhibition and consequence sensitivity. How these components differ from one another in terms of their use, behavioral theory and biological function is discussed, along with measurement techniques.

Biogen Idec and Elan Corporation voluntarily withdrew natalizumab (Tysabri) from the market on February 28 and suspended clinical trials. The move came after 1 patient died and suspected progressive multifocal leukoencephalopathy developed in another.

What actually happens neurochemically in the brain to cause addiction? A well-known researcher discusses her findings on the role that dopamine levels play in addiction and aversion to cocaine.

Many psychiatrists limit the application of their skills to individuals whose discomfort matches the phenomenological criteria of DSM-IV-TR. Can psychiatry transcend the concept of "objective cure" and include "subjective perfection" as a goal? Is there a logical reason why the concept of "treatment pills" cannot coexist with that of "lifestyle pills" on the psychiatric prescription pad? Dr. Giannini reflects on whether there can be both "cosmetic" as well as "reconstructive" psychiatry and if a disease is needed in order to be treated.

Addiction-as-disease or addiction-as-choice may be better defined by delineating initial experimentation with addictive drugs from ongoing drug use. Repeated exposure to addictive substances changes the molecules and neurochemistry of the addict. Addiction-as-disease accepts the responsibility of the health care professional to treat the patient and precludes the stigmatization that addiction is a choice.
