When Gordon R. Kelley, MD, was called to the ICU in Kansas City, Mo, to evaluate a deteriorating patient who had apparently overdosed on methadone, he was puzzled. CT and MRI scans revealed an obstructive hydrocephalus associated with abnormal signals throughout the cerebellum, basal ganglia, and hippocampi. He knew that these findings were not consistent with a typical cerebrovascular injury, but he and other treating physicians were unsure of the cause of the findings. Reaching for his handheld computer, he entered several key words into his favorite program, NERVLINE: cerebellum . . . heroin . . . leukoencephalopathy

Diagnosis of the two main major eating disorders, anorexia nervosa and bulimia nervosa, can be difficult because of denial of symptomatology by the patients and problems with some of the diagnostic criteria. Although CBT has been the most effective, there are no treatments available that can guarantee a cure for either disorder. Medication is only a helpful adjunct to the treatment of anorexia, while many controlled studies that show antidepressant medications are effective in reducing binge/purge behavior in bulimia.

The FDA has issued a "black box" warning about the use of all antidepressants in the pediatric population due to a 1.8-fold increase in suicidality on drug compared to placebo. Yet these medications can be an effective tool in treating depression. How should parents and patients be educated, considering this information?

Autism is a highly prevalent, highly heterogeneous disorder of unknown etiology. Studies to clearly establish the efficacy of various classes of psychoactive drugs are scarce. Nonetheless, available findings do support the efficacy of atypical antipsychotics and antidepressants in treating the core symptoms of repetitive behavior.

Psychiatric evaluation of juveniles who commit murder is perhaps one of the most difficult tasks in forensic psychiatry. A study has shown that these inmates are more likely to have been abused, be addicted to drugs or alcohol, or have a serious psychiatric disorder. Additionally, they are more likely to engage in risky behavior without thinking about the consequences.

Alzheimer disease (AD) affects between 6% and 8% of Americans older than 65 years. As the population of older adults increases, the number of persons with AD is expected to rise from 4.5 million in 2000 to 13.2 million by 2050.1 This disease is important not only because of the number of patients affected but also because it leads to significant physical and emotional burdens on families and caregivers.

Sildenafil (Viagra, Pfizer) may help patients recover from stroke by aiding regeneration of brain cells. After successfully proving that the drug stimulates cortical neurogenesis in experimental models of stroke, researchers from the Henry Ford Hospital in Detroit have now embarked on a clinical trial of sildenafil and plan to recruit 84 patients who have suffered a moderate stroke within 72 hours of entering the study.

Osteoporosis is a disorder characterized by low bone mass and microarchitectural deterioration with resulting compromised bone strength and increased risk of fracture.1 The World Health Organization defines osteoporosis based on T-scores, which reflect bone mineral density (BMD) relative to mean BMD for healthy 25-year-old same-sex populations. A T-score between 0 and 21 is considered normal density, a score between 21 and 22.5 indicates osteopenia, and a score of less than 22.5 signifies osteoporosis.2 Severe osteoporosis is defined as a T-score of less than 22.5 combined with a fragility fracture.2

Little attention has been paid to the prevalence of sexual assault and its sequelae among military men. The past-year prevalence of sexual assault among enlisted men ranges from 0.4% to 3.7%, a figure equal to or exceeding the lifetime prevalence among civilian men in some studies. Increased awareness and understanding of male sexual assault as well as routine screening of all patients, regardless of gender, for exposure to sexual victimization will enhance their recovery.

Road rage is well known in popular culture and to many people it is a common and dangerous experience. Alcohol problems, illicit drug use and general psychiatric distress are associated with road rage perpetration. Road rage incidents may also result in psychiatric distress. Although treatment for road rage has received little research attention, encouraging results have been reported from specialized programs.

Youth gangs are a recognized risk factor for adolescent violence and delinquency. This article reviews recent research on these topics, including the prevalence, characteristics and influence of youth gangs, and discusses the implications of those findings for clinical practice.

Mental illness occurs more frequently among people infected with HIV. In addition, individuals with mental illnesses are at greater risk for contracting HIV. Therefore, psychiatry has a great deal to offer in the management of patients with HIV--whether through proper patient education or safe and effective psychopharmacology.

Multiple studies show that diabetes approximately doubles the risk of comorbid depression. Furthermore, major depressive disorder is a risk factor for the subsequent development of type 2 diabetes mellitus. Treatments for depression in the setting of diabetes must be evaluated for their effects on blood glucose levels, propensity for weight gain, possible concomitant use for diabetic neuropathy and potential drug interactions.

Attempts have been made to integrate psychiatry and medicine as far back as Benjamin Rush, a physician and signer of the Declaration of Independence. Recent advances in research, clinical practice and organizational makeup, however, now make integration seem more plausible than ever. Find out what's happening to bring these two fields closer together.

Management of diabetic peripheral neuropathy (DPN) centers on proper footcare, offloading, and various orthotic devices to prevent the development of ulcers. Management trends, however, show that off-label use of some pharmaceutical agents is common and that these agents are proving beneficial in relieving the pain that can accompany DPN in up to 35% of patients. In addition, innovations in orthotic devices and new technologies for patient monitoring are being rolled out.

Published research is now backing up what would appear to many to be a clear heart and brain connection. As more of this research is circulated, it could have a direct impact on how neurologists practice medicine and on how neurologists and primary care physicians treat patients and interact with each other.

"No longer a pipe dream," is the suggestive lead-in of a widely distributed press release issued last October touting the potential benefits of cannabinoid compounds in the treatment of Parkinson disease (PD), Lou Gehrig disease-or amyotrophic lateral sclerosis (ALS)-and a number of other debilitating conditions, as reported during last fall's 2004 annual meeting of the Society for Neuroscience. According to Daniele Piomelli, PhD, an expert in cannabinoid research and professor in the Department of Pharmacology at the University of California, Irvine, certain cannabinoid compounds can be harnessed to "provide select benefits to patients while avoiding some of the unwanted effects" associated with marijuana use. Compounds of greatest interest have been WIN 55212-2, delta(9)-tetrahydrocannabinol (THC), and anandamide.

The post-stroke patient is at significant risk for various psychiatric syndromes. The most commonly reported of these in the literature are post-stroke depression (PSD) and post-stroke dementia (PSDem), which may present simultaneously with overlapping mood and cognitive symptoms. In this article, we offer a review of current literature on post-stroke psychiatric syndromes and an integrated clinical approach to screening, diagnosis, and pharmacologic intervention.

Some patients with epilepsy have more treatment options today because of constantly expanding computer power, the development of model neurons and neuronal networks, and the ability of neurologists and neurosurgeons to translate medical and scientific research into clinical practice.

Since the 1990s there has been an increase in research on sexual harassment and its mental health consequences. These researchers discuss the use of alcohol to self-medicate harassment-engendered distress and the need for greater attention to potential alcohol-related consequences of harassment experiences.

In the past decade, important advances have been made in detecting and treating substance abuse disorders. In addition, research has revealed influences on the etiology and course of SUDs. Dr Pettinati introduces this Addictive Disorders Special Report, noting that the articles add to this knowledge base.
