Comorbidity

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

The assessment and treatment of psychiatric symptoms in persons with cognitive dysfunction are becoming increasingly important. Prevalence estimates of dementia in the United States range from 5% in those aged 71 to 79 years to 25% to 50% in those 90 or older.

Autism spectrum disorders (ASDs) are a group of 5 neuro developmental conditions (autism, Asperger syndrome, pervasive developmental disorder not otherwise specified [PDD-NOS], Rett syndrome, and disintegrative childhood disorder).1 Once thought to be rare, the incidence of these disorders is now estimated to be 1 in 150 children in the general population.2 Furthermore, the number of recognized cases has increased markedly in recent years.

The co-occurrence of obsessive-compulsive symptoms (OCS) and psychotic illness has been a challenge for clinicians and investigators for more than a century. Over the past decade, interest in this area has burgeoned because of recognition of higher-than-chance comorbidity rates of schizophrenia and OCD.

What exactly is a “mental disorder”? For that matter, what criteria should determine whether any condition is a “disease” or a “disorder”?

The central tenet of clinical comorbidity, the occurrence of 2 syndromes in the same patient, presupposes that they are distinct categorical entities.

This article emphasizes core philosophies and components of effective dual disorder programs.

Generalized anxiety disorder (GAD) is a prevalent, chronic, debilitating mental illness associated with marked impairment in daily functioning.1 An ongoing evolution of the definition of GAD has resulted in a bifurcation of the historical anxiety neurosis designation.2 A diagnosis of GAD currently implies chronic, excessive worry lasting at least 6 months and 3 of the possible 6 somatic or psychological symptoms (restlessness, fatigue, muscle tension, irritability, difficulty concentrating, and sleep disturbance).3 GAD typically presents in an episodic pattern of moderate improvement or remission and relapse characterized by a chronic and complicated clinical course.

The cardiovascular properties of serotonin (5-HT) have been known for some time-its name reflects its presence in serum and its action in increasing vascular tone. Serotonergic medications are routinely used to treat depressive and anxiety disorders, and the association of depression with cardiovascular disease has become well established.2 Recent studies have confirmed the colloquial wisdom that anxiety (especially panic) and hypertension are linked.

The rationale for the use of anticonvulsants in anxiety disorders is supported by neurobiological underpinnings that make these compounds a likely alternative for short-term treatment.

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.

Suicide risk assessment is a core competency that all psychiatrists must have.1 A competent suicide assessment identifies modifiable and treatable protective factors that inform patient treatment and safety management.2 Psychiatrists, unlike other medical specialists, do not often experience patient deaths, except by suicide. Patient suicide is an occupational hazard. A clinical axiom holds that there are 2 kinds of psychiatrists: those who have had patients commit suicide-and those who will.

Late-life depression is both underrecognized and undertreated, and the impact of medical comorbidity may mask depressive symptoms. Depression further complicates the prognosis of medical illness by increasing physical disability and decreasing motivation and adherence to prescribed medications and/or exercise or rehabilitation programs

Chronic posttraumatic stress disorder (PTSD) may occur secondary to combat, terrorism, civilian assaults including physical and sexual abuse, or other traumatic experiences.

Our returning military veterans remind us dramatically of the importance to consider traumatic brain injury (TBI) as a potential comorbid illness in cases of posttraumatic stress disorder (PTSD). The common causes of comorbid TBI and PTSD are assault and battery to the head, head trauma (personal or work-related injuries), civilian or military explosions, inflicted head trauma in children, motor vehicle accidents, and suicide attempts by jumping. Prevalence figures for comorbid TBI and PTSD historically have been lacking

Late-life depression is both underrecognized and undertreated. The impact of medical comorbidity may mask depressive symptoms.

The National Comorbidity Survey estimates that approximately 50% of the population in the United States is exposed to traumatic events and that the lifetime prevalence of posttraumatic stress disorder (PTSD) is approximately 7.8%.

DSM-IV-TR, our current diagnostic classification system of psychiatric disorders, follows the diagnostic paradigm first established by DSM-III in 1980.

Reducing complex human experiences into a psychiatric diagnosis can be a daunting task. For children with developmental disorders, this process is even more complicated and requires distilling often incomplete and frequently contradictory scientific evidence.

Recent research has raised concerns about the adequacy of psychiatric diagnostic evaluations conducted in routine clinical practice, particularly the detection of disorders that are comorbid to the principal diagnosis.

Diagnostic assessment of psychiatric disorders and their comorbidities is a challenge for many clinicians. In emergency settings, there is no time to conduct lengthy interviews, and collateralinformation is often unavailable.

Emergency medicine provides care to a vast number of patients each year. In 2005, 115.3 million people visited emergency departments (EDs).

Gambling has become a major recreational activity in the United States. Formerly confined to a few states such as Nevada and New Jersey, legal gambling opportunities have exploded across the nation in the past 2 decades.

The high rate of comorbid substance abuse in women with bulimia nervosa (BN) has remained consistent in the literature. This article reviews the prevalence of substance abuse in BN and summarizes treatment approaches for persons with BN and comorbid substance abuse.

Adolescents who present with symptoms that suggest a psychotic disorder pose a number of diagnostic and treatment challenges. This article attempts to provide a practical guide to the assessment and management of adolescents with severe psychotic illness, including schizophrenia, schizophrenia-like disorders, and bipolar disorder.

A 52-year-old female college professor was referred to a psychiatrist by a nurse practitioner at the college health clinic. The referring diagnosis was “adjustment disorder with depressed mood versus atypical depression with somatization; rule out fibromyalgia.”

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

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