ADHD

Any person who once “drew a blank” during an exam is familiar with the horrors of cognitive difficulties: that terrible moment is for most of us so rare that it remains a traumatic memory for years to come. Imagine those who suffer from protracted cognitive difficulties.

In my January column (“Fishing Expeditions and Autism: A Big Catch for Genetic Research?” Psychiatric Times, January 2009, page 12), I described the great difficulties research­ers face characterizing the genetic basis of the disease. Complexities range from trying to establish a stable diagnostic profile to making sense of the few isolated mutations that show clear associations (either with disease or syndrome variants).

The prescription of psychotropic medications for children continues to be a controversial area of medical practice. In the United States, academic medical centers, medical researchers, prescribers, and the FDA are all ostensibly committed to the common goal of disseminating accurate information and promoting treatment based on scientific evidence. In the United States, however, medical treatment takes place in the context of legal and pervasive direct-to-consumer advertising (DTCA). There are concerns about the potential for DTCA to affect public health negatively and to increase health care costs.

Attention-deficit-hyperactivity disorder (ADHD) is one of the most widely diagnosed disorders: an estimated 8% to 12% of children are affected worldwide. Although many studies about treatment options have been published, we are still discovering the genetic components that underlie the disorder. A special issue of the American Journal of Medical Genetics, Part B: Neuropsychiatric Genetics, highlights recent research and includes results from the first genome-wide study of patients with ADHD. Genome-wide studies have successfully identified variants associated with obesity and such diseases as age-related macular degeneration, diabetes, and prostate cancer.

My first job after residency involved working at a large Veterans Affairs hospital in an outpatient dual diagnosis treatment program that focused on the comorbidity of schizophrenia and cocaine dependence. Having recently completed a chief resident position at the same hospital’s inpatient unit that focused on schizophrenia without substance abuse, I was struck by how “unschizophrenic” my new patients were. They were organized and social. Their psychotic symptoms were usually limited to claims of “hearing voices,” for which insight was intact and pharmacotherapy was readily requested.

The words attributed to Socrates resonate with the perspectives of many contemporary parents and clinicians.1 The endurance of the concern suggests something fundamental about the psychopathology of deviant, disruptive behavior of youth. Yet clinicians struggle to understand its origins, to help parents control their children, and to help the children control themselves. Clinically, this manifests in failed pharmacological treatments, incompleted courses of individual therapy, problems in engaging families in treatment, and controversies over which therapy is most effective.

Does adoption pose psychological risks? University of Minnesota researchers revisited this controversial issue recently and found that common DSM-IV childhood disorders are more prevalent in adoptees than nonadoptees.

A large percentage of youths use and abuse psychoactive substances. According to the 2007 Monitoring the Future (MTF) survey, the percentage of US adolescents who used illicit drugs or drank alcohol continued a decade-long drop, revealing that 19% of 8th grad­ers, more than 36% of 10th graders, and 47% of all 12th graders have taken an illicit drug (other than alcohol) during their lifetime.1 According to the National Survey on Drug Use and Health, the rate was 3.3% for misuse or nonmedical use of prescription drugs.2 The misuse of prescription drugs among adolescents was second only to marijuana use. In fact, prescription drugs increasingly have become a part of the repertoire of drug-using adolescents.

Youths aged 6 to 16 years with any subtype of ADHD participated in the study. Comorbid bipolar disorder, pervasive developmental disorder, psychotic illness, anxiety disorders, and tic disorders were exclusionary criteria. Patients with other comorbid psychiatric disorders, including major depressive disorder, were allowed to participate if ADHD was the primary diagnosis.

Major depressive disorder has become psychiatry’s signature diagnosis. Depression is diagnosed in about 40% of patients who see a psychiatrist. This percentage is double that of just 20 years ago.

Participants from around the globe recently came together to create an international consensus statement on bipolar disorder that was presented at the 21st Congress of the European College of Neuropsychopharmacology (ECNP).

Too often news headlines exert a major influence on our patients-and nothing in child psychiatry grabs headlines like the alleged overprescription of medicines. Physicians sidestep the debate, assuring their patients and themselves that each prescription is written only after careful consideration of risks and bene-fits.

Medication adherence, especially in children and adolescents, is a complex problem that is poorly understood and underresearched, yet it is a clear barrier to effective treatment and is frequently encountered in everyday clinical practice.

Two recent studies on the treatment of depression in children and adolescents will help guide clinicians’ treatment decisions.

ADHD, the most common diagnosis in child psychiatry, appears to be more challenging to diagnose and treat when there is a comorbid depressive disorder.

Elder abuse is a concern for all practitioners who care for elderly patients or their family members. An elderly person’s fears of aging and dependence may be heightened by stories and news accounts of abuse.

This article focuses on recent innovations in diagnostic issues, tactics, and strategy, and takes a brief look at the future.

Debates over conflicts of interest (COIs) in medical research and practice are intensifying with recent proposals to ban industry funding of medical education, to better “manage” industry-physician relationships, and to mandate public disclosure of industry payments to physicians and medical institutions. Caught in the cross fire are prominent psychiatrists accused of underreporting payments received from pharmaceutical companies.

Two recent studies present clinical evidence that the use of stimulants to treat boys with attention deficit hyperactivity disorder (ADHD) does not increase their risk of later substance use disorders. This evidence provides clinicians and families with much needed reassurance.

In the era of genomics, psychiatry-like all areas of medicine-will likely undergo radical change. As genetic risk factors are uncovered and the dynamic nature of gene expression is elucidated, novel approaches to prevention will diminish or preempt diagnosis and treatment for many psychiatric and neurobehavioral disorders.

In clinical medicine, the term recovery connotes the act of regaining or returning to a normal or usual state of health. However, there is lack of consensus about the use of this term (which may indicate both a process and a state), as well as of the related word remission, which indicates a temporary abatement of symptoms. Such ambiguities also affect the concepts of relapse (the return of a disease after its apparent cessation) and recurrence (the return of symptoms after a remission).

There is substantial comorbidity with oppositional defiant disorder (ODD) and conduct disorder (CD) in children with attention-deficit/hyperactivity disorder (ADHD). It is important to determine the effect of comorbid ODD and CD on the clinical course in youth with ADHD. Biederman and associates1 recently published clinical findings from a 10-year prospective, longitudinal study of boys with ADHD, following them into early adulthood.

In the past several years, there has been an increasing awareness of the syndromal persistence of ADHD into adulthood. Once considered only a childhood disorder, ADHD has become increasingly recognized as a valid psychiatric disorder in adults.

"I've lost my interest in sex." As psychiatrists, we hear this concern (if we ask) from women in a variety of situations: those who are depressed, postpartum, menopausal, traumatized, and those who have been treated with psychotropic medications. Thankfully, we have many interventions, both behavioral and pharmacological, to use in addressing sexual issues.

An international team of experts recently proposed expanding the diagnostic criteria for several subtypes of bipolar disorder, adding a pediatric bipolar disorder category and eliminating the schizoaffective disorder category.

Recently, a number of studies have examined the characteristics of early-onset schizophrenia spectrum disorders and medication treatment for youths with schizophrenia.

Evidence-based medicine (EBM) is rapidly becoming the norm. It is taught in medical schools and is encouraged by both government agencies and insurance plan providers. Yet, there is little proof that this model can be adapted to fit psychiatry.

Although there is evidence in the research literature from as far back as 40 years showing that the symptoms of attention-deficit/hyperactivity disorder (ADHD) often persist into adulthood, it has been only in the past decade or so that integrative treatment models designed specifically for adult ADHD have been developed.
