Ethical Questions at the Intersection of Neurotechnology and Psychiatry

Digital technology has transformed the way people live, work, and play. We are now able to instantly communicate with anyone, anywhere, anytime; however, an overload of technology can be counterproductive.

Transcranial magnetic stimulation (TMS) is noninvasive focused brain stimulation that uses pulsed magnetic fields. The underlying mechanism depends on the principle of electromagnetic induction, the process (discovered by Faraday in 1839) by which electrical energy is converted into a magnetic field and vice versa.1

Bioethicists often debate whether the rapid pace of medical science truly generates new ethical questions or whether what appear to be novel dilemmas are really ancient conflicts presented in modern terms and contexts.1 The valuable essays in this Special Report offer support for each position and, more important, provide clinical wisdom for mental health professionals struggling with ethical issues both profound and prosaic in a variety of practice settings.

My “most important achievement to date” is that I’m capable of even the simplest forms of basic cognition. I can remember, perceive, speak, feel, think, solve, and-sometimes-pay attention.

The recently posted first draft of DSM-5 has suggested a whole new category of mental disorders called the "Behavioral Addictions." The category would begin life in DSM-5 nested alongside the substance addictions and it would start with just one disorder (gambling).

There are limited data on clinical and biological predictors of antipsychotic drug response. The ability to identify those patients who will respond well to psychotropic drug treatment or who will be at a higher risk for adverse effects could help clinicians avoid lengthy ineffective drug trials and limit patients’ exposure to those effects. Moreover, better predictability of treatment response early in the course of a patient’s illness can result in enhanced medication adherence, a significant predictor of relapse prevention.

Available treatments are so robust that nearly one-third of patients with major depression will achieve full clinical remission with monotherapy.

Traumatic brain injury (TBI) affects approximately 2 of every 1000 persons per year. Persons vulnerable to mental illness (eg, persons with alcohol abuse or antisocial personality disorder) are particularly at risk.

Given the potential for a significant role in recognition of neurologically complex disorders, psychiatrists should become familiar with diagnostic criteria and appropriate therapeutic option.

Parkinson disease (PD) is the second most common neurodegenerative illness in the United States, affecting more than 1 million persons. Disease onset is usually after age 50. In persons older than 70 years, the prevalence is 1.5% to 2.5%.1 While the primary pathology involves degeneration of dopaminergic neurons in the substantia nigra, circuits important in emotion and cognition-such as the serotonergic, adrenergic, cholinergic, and frontal dopaminergic pathways-are also variably disrupted.

The issues being debated here have important long-term implications for psychiatry, and we are pleased to present these revised versions of 2 principal presentations.

Another lifetime ago-just after leaving residency-I took a job as a psychiatric consultant at a large, university mental health center. Had I known the poisoned politics of the place, I would have headed for someplace safe-like, say, Afghanistan.

This article reviews the differences between dementia types and future directions.

Practical approaches to integrating 3 aspects of a suicide assessment have been well delineated for adults and adolescents.

Of the screening tools available to help identify early symptoms of Alzheimer’s disease, which is best?

Repetitive transcranial magnetic stimulation (rTMS) may be an effective therapy for treatment-resistant bipolar depression, according to the results of a recent pilot study led by Guohua Xia, MD, PhD, assistant clinical professor of psychiatry at the University of California, Davis.

Information transmission, such as blogs, RSS feeds, and podcasts, have emerged as common forms of communication. The exponential growth of medical knowledge and the increasingly rapid pace of scientific discovery have made it nearly impossible for the print medium to keep abreast of new developments.

The editors of Psychiatric Times interview Vladimir Maletic, MD, PA, clinical professor of neuropsychiatry and behavioral science at the University of South Carolina School of Medicine, Columbia; founding member of the Integrative Neurobiology Educational Alliance; and member of the U.S. Psychiatric and Mental Health Congress 2009 advisory board.

Transcranial magnetic stimulation produced improvements in key areas of cognition and in short-term verbal memory in patients with major depressive disorder, and no adverse cognitive effects were shown. The results of this research were presented by Mark Demitrack, MD, vice president and chief medical officer of Neuronetics, Inc, and colleagues at the annual meeting of the American Psychiatric Association in May.

Whether you credit the idea to Niels Bohr or Yogi Berra, it is true that predictions are very difficult to make, especially about the future. It is a daunting task, yet obviously an intriguing one, to try to imagine what our field will be like in 10 years or more.

From this book’s title, iBrain, I expected to learn about the positive impact of the computer world on the ever-evolving brain. I was in for a surprise. iBrain is a nuanced account of brain anatomy and function, brain plasticity, the impact-good and bad-of the Internet and Web access on the brain, and how to have a healthy brain and life in the face of our technological world. The book is written by psychiatrist-neuroscientist Gary Small, MD, director of the Memory and Aging Research Center at UCLA, and his wife, Gigi Vorgan, a film and television actor and writer. Small and Vorgan have a linear, easy-to-understand writing style that includes entertaining and educational case vignettes.

Mr A is a 73-year-old resident of a nursing home, where the irate aides describe him as “a liar and a troublemaker.” Mr A’s “stories” were regarded by the staff as deliberate mischief on his part.

Several classes of hypnotic medication are available: the older barbiturates and their derivatives; benzodiazepines; chemically distinct “z-compounds”; antihistamines and antihistaminic antidepressants; and melatoninergic compounds. The use of hypnotic medications continues at a high rate. However, some switching to the shorter-acting benzodiazepines has occurred. The z-compounds-eszopiclone, zolpidem, and zaleplon-have become popular; they seem to have fewer residual effects than the benzodiazepines. Even so, care is needed in prescribing such hypnotics for the elderly.

Lecturing around the country has left us with the powerful impression that both psychiatrists and primary care physicians are hungry for new ways to think about and treat depression and the myriad symptoms and syndromes with which it is associated-including attention deficit disorder, insomnia, chronic pain conditions, substance abuse, and various states of disabling anxiety. Primary care physicians also seem especially excited to learn that depression is not just a psychiatric illness but a behavioral manifestation of underlying pathophysiological processes that promote most of the other conditions they struggle to treat-including cardiovascular disease, diabetes, cancer, and dementia.1,2

Many people assume that it is the emotional and psychotic symptoms that make it difficult for a person with schizophrenia to function in everyday life. In fact, research indicates that cognitive impairment is a major reason why functional outcome is so poor.1

Eli Lilly and Company pleaded guilty on January 30 to one misdemeanor violation of misbranding Zyprexa (olanzapine) by promoting it for dementia. However, a question raised by bloggers and others remains: did the drug benefit the elderly despite the fact it was not approved by the FDA for such purposes?

While ECT remains a remarkably safe and effective treatment for severe depression, its broad application has been hampered by concerns-both perceived and real-about its cognitive effects.5 Worries about memory loss make some patients reluctant to undergo this therapy and some practitioners reluctant to refer patients for it. Within the field of ECT itself, there has been tension for some years between the wish to maximize (the already excellent) antidepressant and antipsychotic efficacy of ECT and the competing wish to minimize any effects on memory.

Because numerous diseases- infectious, endocrinological, metabolic, and neurological, as well as connective-tissue disease-can induce psychiatric and/or behavioral symptoms, clinicians need to distinguish these neuropsychiatric masquerades from primary psychiatric disorders, warned José Maldonado, MD, the director of Stanford University’s Psychosomatic Medicine Service.

A new study is raising important questions about the brain’s ability to remain active and regenerate in later life and whether Web searching can stimulate brain activity in middle-aged and older adults.
