Neuropsychiatry

Neuroimaging is often used in clinical psychiatry to rule out medical and neurological conditions that can mimic psychiatric disease rather than for the diagnosis of specific psychiatric disorders.

Unipolar major depressive disorder is a debilitating condition with a lifetime prevalence of 17%. Recent epidemiological evidence indicates that MDD is the fourth leading cause of disease burden and the leading cause of disability-adjusted life years.

Universal prevention has been a focus of psychiatric research for the past 4 decades. Using a public health approach, research has shown that mitigating major risk factors, such as poverty and early life stress, and promoting protective factors can improve behavioral outcomes.

Depression complicates medical illnesses and their management, and it increases health care use, disability, and mortality. This article focuses on the recent research data on diagnosis, etiopathogenesis, treatment, and prevention in unipolar, bipolar, psychotic, and subsyndromal depression.

Traumatic brain injury (TBI) is the major cause of death and disability among young adults. In spite of preventive measures, the incidence of a TBI associated with motor vehicle accidents, falls, assault, and high-contact sports continues to be alarmingly high and constitutes a major public health concern. In addition, the recent military operations in Iraq and Afghanistan have resulted in a large number of persons with blast injuries and brain trauma. Taking into account that cognitive and behavioral changes have a decisive influence in the recovery and community reintegration of patients with a TBI, there is a renewed interest in developing systematic studies of the frequency, mechanism, and treatment of the psychopathological alterations observed among these patients.

The mind-brain dichotomy has been on a roller-coaster ride over the past few hundred years. Clinically astute European neuropsychiatrists in the 18th and 19th centuries described various neuropsychiatric disorders based on observations of their patients.

Despite an abundance of studies linking both traumatic experiences and anxiety disorders with eating disorders, relatively little has been reported on the prevalence of associated posttraumatic stress disorder (PTSD) or partial PTSD in patients with eating disorders.

The Psychodynamic Diagnostic Manual1 (PDM) was created by a task force chaired by child psychiatrist Stanley Greenspan, MD, in cooperation with the American Psychoanalytic Association, the International Psychoanalytical Association, the Division of Psychoanalysis of the American Psychological Association, the American Academy of Psychoanalysis and Dynamic Psychiatry, and the National Membership Committee on Psychoanalysis in Clinical Social Work.

From Our Readers

In recent years, we have learned a great deal about posttraumatic stress disorder (PTSD) and its public health implications. From 9/11 to Katrina and the present Iraq war, PTSD has been in the forefront of health concerns and public policy.

The number of prescriptions for antipsychotic treatment of teenagers has increased sharply in office-based medical practice. Adolescents with psychotic symptoms frequently present for clinical evaluation, and early-onset schizophrenia spectrum disorders (onset of psychotic symptoms before the age of 18 years) represent an important consideration in the differential diagnosis in these youths

No other psychiatric diagnosis has more profound negative implications than autism. On the surface, autism impacts social, emotional, behavioral, and academic functioning. However, autism is pervasive in ways less immediately observable, and, as a result, children with autism require developmental and educational interventions that are different in both form and intensity from those required by children with other special needs.

It is my great honor and pleasure as a psychiatric educator to teach many excellent medical students and residents. These young and not-so-young men and women are by and large diligent, highly professional, and caring.

Evidence for Use of Neurostimulating Techniques

In May 2007, the novelist Ann Bauer went public with the tribulations of her autistic son. When catatonia developed, a diagnosis of schizophrenia was made, and antipsychotic medications were prescribed, but with little benefit. When the catatonia syndrome was recognized as independent of schizophrenia and successfully treated, her son returned to a more normal life.1,2

The adage has it that the road to hell is paved with good intentions. It is evident from this revealing portrait of neurologist Walter Freeman--the originator of the infamous "ice pick" lobotomy--that good intentions without sober analysis can indeed have hellish consequences.

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.

The clinical diagnosis of Pick disease can be one of the most difficult facing the neurologist. Those patients found to have lobar atrophy usually present clinically with bouts of irrational behavior, bulimia, marked reductions in speech, abulia, and apathy.

Attachment may be defined as a composite of behaviors in an infant, toddler, or young child that is designed to achieve physical and emotional closeness to a mother or preferred caregiver when the child seeks comfort, support, nurturance, or protection.

During the past decade, a great deal of research has been undertaken to better understand the pathogenesis of neurodegenerative diseases. Data from stroke models has shown that the semisynthetic tetracycline antibiotic minocycline can mediate neuroprotection in neurodegenerative diseases by inhibiting caspase-1 and inducible nitric oxide synthase (iNOS) activity.

Book Review

In our presentation at the 2006 annual meeting of the American Academy of Child and Adolescent Psychiatry, we suggested that child psychiatrists who come across a child with the profile of the following hypothetical case should consider whether the child may have deficits that are not currently covered by DSM-IV nosology: either a nonverbal learning disability (NVLD) or a sensory processing disorder (SPD).

Epidemiological studies report a lifetime prevalence rate of 24.9% for (any) anxiety disorder. Feelings of anxiety can also be related to normal fear of pain, loneliness, ridicule, illness, injury, grief, or death. In both these types of situations, anxiety can be difficult to deal with. Consequently, benzodiazepines, which offer almost immediate symptomatic relief for anxiety, can be quite appealing to many persons.

Civilian cases of traumatic brain injury (TBI) account for more than 50,000 deaths annually and represent about 50% of deaths attributed to physical injury. These injuries are a significant medical and socioeconomic burden and represent one of the leading public health problems in the United States. However, thanks to injury prevention and changes in hospital admission practices, a decline of almost 50% in civilian hospitalizations for TBI has been observed since 1980, with many patients now treated on an outpatient basis.
