People with fibromyalgia syndrome (FMS) experi-ence unrefreshing sleep, aches, hypersensitivity, and cognitive and emotional difficulties. Although no specific causative factor or biological agent is known to account for all of the features of FMS and these related diagnoses, the generalized hypersensitivity of the body is considered to be affected by disturbances in cen-tral nervous system (CNS) functions. Such CNS dis-turbances are intrinsic to the sleeping-waking brain, where the common symptom elements in all these illnesses are poor quality of sleep, nonspecific pain, fatigue, and psychological distress in the absence of known disease pathology.

Introduction: A growing number of studies have suggested that maternal exposure to post-tricyclic antidepressants during pregnancy might be associated with an increased risk of poor birth, obstetrical, and neonatal outcomes. Among these complications, the occurrence of spontaneous abortions represents one of the most dramatic events for the pregnant woman.

Methods: The purpose of this study was to review all studies reporting primary data investigating the rate of spontaneous abortions in women treated with selective serotonin reuptake inhibitors during pregnancy. Medical literature information published in English since 1980 was identified using MEDLINE/PubMed, TOXNET, EMBASE, and The Cochrane Library. Searches were performed using various combination of search terms and were last updated May 2008. No other limitations were imposed. Twelve articles reporting primary data on the rate of spontaneous abortions in women treated with selective serotonin reuptake inhibitors or serotonin-norepinephrine reuptake inhibitors during early pregnancy outcome of pregnancies exposed to antipsychotics were selected for the review. The author was the only reviewer who performed selection and data extraction.

Results: Information from reviewed studies are scarce and methodologically inadequate to draw definitive conclusions about the hypothesized risk of spontaneous abortions associated with serotoninergic antidepressant exposure during early pregnancy.

Problems with memory are a very common complaint in the elderly and are not synonymous with dementia. Some degree of cognitive decline, manifested as greater difficulty in learning and retrieving new information for instance, develops with normal aging. Thus many older patients do not perform at the same level they did when they were younger but they do perform well when compared to their peers. For many, cognitive change ends at this stage and they proceed to lead normal, healthy, dementia-free lives.

The cohort that has cognitive changes beyond what is expected in normal aging but does not yet meet criteria for dementia concerns clinicians greatly as many of these patients eventually become demented. These patients usually go through a latent stage in which neurodegenerative pathology silently spreads in the brain. Once there is enough pathological burden, cognitive decline beyond what is expected for normal aging can be detected by formal neuropsychological testing. Frequently such patients go through a state called mild cognitive impairment (MCI). In this state patients are still functionally intact and live independently, but show cognitive impairment relative to the age- and education-adjusted norms.

The MCI state in itself is a prominent risk factor for developing dementia. Most patients with amnestic MCI develop Alzheimer’s disease (AD) dementia over time. At six years, as many as 80% progress to AD. Thus, MCI is a very important topic of research and an increasingly important topic of clinical care.

Primary care physicians (PCPs) often provide the first line of care for the vast number of United States adults—∼30% at any given time—with either a psychiatric or a substance use disorder, or both. The widespread prevalence of this comorbidity bears reiterating: During the same 12-month period, 20% of national survey respondents with a substance use disorder (SUD) had at least one mood disorder, and 17% had at least one anxiety disorder. Conversely, at least one SUD was found among 20% of respondents with a mood disorder and 15% of those with an anxiety disorder. However, because PCPs are often not aware of or alerted to these problems, it would seem advisable that patients presenting with either a psychiatric or an alcohol use disorder should be evaluated for both conditions. Establishing the presence of co-occurring disorders may be difficult, but it is necessary for appropriate and realistic treatment planning.

Physicians treating patients with serious mental illness need to overcome a number of hurdles to ensure that appropriate health care is provided to these often underserved patients. The Community Mental Health Act of 1963 established community mental health centers (CMHCs) that provide patients with access to psychiatric care, with the unintended consequence of separating mental health care from physical care. CMHCs do not always have adequate resources to screen, monitor, and treat cardiovascular disease (CVD): they lack sufficient funding, have limited staff, and often do not have laboratory facilities for monitoring lipids and blood glucose.

Somatization disorder is a somatoform disorder that overlaps with a number of functional somatic syndromes and has high comorbidity with major depression and anxiety disorders. Proposals have been made for revising the category of somatoform disorders, for simplifying the criteria for somatization disorder, and for emphasizing the unitary nature of the functional somatic syndromes in future classifications. A review of the cognitive-affective neuroscience of somatization disorder and related conditions suggests that overlapping psychobiological mechanisms mediate depression, anxiety, and somatization symptoms. Particular genes and environments may contribute to determining whether symptoms are predominantly depressive, anxious, or somatic, and there are perhaps also overlaps and distinctions in the distal evolutionary mechanisms that produce these symptoms.

Comorbid chronic pain is common in depressed patients. It is predictive of a poor prognosis for depression and is a major risk factor for suicidal behavior. Depression and chronic pain may result from a common neurobiological dysfunction of monoamine cell bodies in the basal ganglia. Amitriptyline, which inhibits both serotonin and norepinephrine reuptake, is a preferred treatment of chronic pain although it is not officially indicated for this condition. Chronic pain can be modeled in animals where amitriptyline has been shown to be highly effective. Similar effects are obtained with the serotonin norepinephrine reuptake inhibitors milnacipran, duloxetine, and venlafaxine, whereas selective serotonin reuptake inhibitors (SSRIs) are only weakly active. Both animal and clinical studies of chronic pain show that dual-acting reuptake inhibitors are more active than selective norepinephrine reuptake inhibitors, which are, in turn, more active than SSRIs. A meta-analysis of placebo-controlled studies confirmed that dual-action antidepressants, but not SSRIs, were effective in reducing chronic lower-back pain. Milnacipran, duloxetine, and venlafaxine, have all been reported to be effective in a number of chronic pain conditions, including the treatment of fibromyalgia where their analgesic effects are independent of comorbid depression.

Mr. F is a 60-year-old Caucasian, married, unemployed male who presented to the outpatient department of the Veterans Administration (VA) ∼10 months ago with a chief complaint of sleep difficulties. Approximately 12 years ago he had been diagnosed with posttraumatic stress disorder (PTSD) and a major depressive episode (MDE). He received very little treatment, either medication or therapy, at that time. He presented after being followed in a Veteran's Center for weekly to biweekly supportive therapy with a counselor for ∼6 months. He had gone to the Veteran's Center due to the encouragement of his wife. She had noted that he was becoming increasingly irritable and isolative at home and she had asked him to seek help for his anger and irritability. An event occurred in which he broke a chair after watching war-related news coverage and that made her insist that he present for treatment.

Compulsive hoarding is a common and often disabling neuropsychiatric disorder. This article reviews the phenomenology, etiology, neurobiology, and treatment of compulsive hoarding. Compulsive hoarding is part of a discrete clinical syndrome that includes difficulty discarding, urges to save, clutter, excessive acquisition, indecisiveness, perfectionism, procrastination, disorganization, and avoidance. Epidemiological and taxometric studies indicate that compulsive hoarding is a separate but related obsessive-compulsive spectrum disorder that is frequently comorbid with obsessive-compulsive disorder (OCD). Compulsive hoarding is a genetically discrete, strongly heritable phenotype. Neuroimaging and neuropsychological studies indicate that compulsive hoarding is neurobiologically distinct from OCD and implicate dysfunction of the anterior cingulate cortex and other ventral and medial prefrontal cortical areas that mediate decision-making, attention, and emotional regulation. Effective treatments for compulsive hoarding include pharmacotherapy and cognitive-behavioral therapy. More research will be required to determine the etiology and pathophysiology of compulsive hoarding, and to develop better treatments for this disorder.

In this contribution to the CNS Spectrums neuroanatomy series, Stefanie Geisler, MD, discusses the lateral habenula (LHb). This nuclear complex is one of the areas of the brain that forms part of the cross-talk between limbic fore-brain and some important ascending modulatory pathways. Situated at the caudal end of the dorsal diencephalon and classically regarded as projecting largely to the brainstem, including the serotoninergic raphe nuclei, the LHb receives afferents from widespread forebrain areas. Therefore, the LHb is able to influence serotonin tone in the brain, and has long interested neuroanatomists as a potential limbic-motor interface. Nonetheless, the LHb was not much discussed outside neuroanatomical circles until recently, when it was discovered that its impact on the mesotelencephalic dopamine system is probably much greater than had been assumed. The LHb has become a hot topic. This article-addresses these developments and emphasizes the clinical relevance of this interesting brain structure.

Introduction: This report demonstrates parameters of quality of care and treatment outcome of acute schizophrenia patients who were involved as subjects in a clinical trial of two marketed widely used antipsychotics compared with their fellow patients who received routine clinical hospital care.

Methods: Patients were newly admitted severely agitated schizophrenia patients who agreed to participate in a double-blind randomized trial of short-term (5 days) rate of improvement in response to two second-generation oral antipsychotics. Treatment outcomes as measured by the Clinical Global Impression and parameters of quality of care were compared with the general population of inpatients in the same county hospital.

Results: Of 145 patients screened, 109 patients did not meet study inclusion and exclusion criteria. It is of note that systematic diagnostic interview did not confirm the clinical diagnosis of schizophrenia in 17 patients (11.7%). Study patients had shorter length of stay (6.75 days vs 15.3 days of total psychiatric patients at the hospital during the study period), no physical restraints (vs 21.9%), no use of antipsychotics as chemical restraints (vs 19.8%), and less recidivism following the trial (28.1%) compared with prior to the trial (64.3%).

Conclusion: Patients who participate in structured clinical research with well-delineated procedures, clinical outcome measures, and clear expectations, faired better than their fellow patients in the same non-research hospital wards. Application of some characteristics of clinical research to the diagnosis and treatment of clinical non-research patients may be considered.

Panic disorder seems to be mediated by the neuronal circuitry and neurochemical systems that have evolved to respond to external threatening stimuli. Distant threats activate prefrontal cortex (involved in complex planning of avoidance strategies), while immediate threats activate midbrain structures (involved in fast reflexive behaviors). Panic disorder may, however, also involve more specific interoceptive mechanisms. For example, the association between respiratory dysfunction and panic disorder has bolstered a false suffocation alarm hypothesis. Genetic and environmental contributors to panic disorder are beginning to be delineated. Effective pharmacotherapy and psychotherapy are able to normalize the relevant psychobiology.

This article describes the spectrum of recurrent thoughts and behaviors that can result from frontotemporal dementia (FTD) and its variants. Although repetitive behaviors can result from a range of brain disorders, FTD is the most common neurologic cause of new-onset recurrent thoughts and behaviors in middle or late life. Patients with FTD can manifest typical or bizarre compulsions, hoarding, verbal and motor stereotypies and complex tics; self-injurious acts, perseverations; and fixed, obsessional thoughts. The frequency and variability of these repetitive behaviors suggest a common disturbance of orbitofrontal-basal ganglia circuits involved in response inhibition. The amelioration of these recurrent events with the administration of serotonin selective reuptake inhibitors further suggests a serotonergic deficit.
