In this case report, the syndrome of acquired stuttering is described including its etiology, common presenting features, and differences from developmental stuttering. A case is described in an elderly female patient with sudden acquired stuttering associated with ischemic infarct near the left basal ganglia.

The transition from reproductive age to menopause is a major milestone in the female lifecycle. It is a hormonal process with a very clear end result: a menopausal state—though its commencement is gradual and vague. It is unavoidable and perfectly normal. The age of the transition varies widely, a fact that hints at the possibility that the reproductive clock is individualized, ticking at a diversified pace. Therefore, the study of the menopausal transition may actually be a derivative of the study of reproduction because it marks the closing of that chapter in a woman's life.

In a sequential approach, the period of transition is defined as perimenopause, or the menopausal transition, the beginning of the second phase in the life of the adult woman, characterized by a stable, low level of gonadal steroids, as opposed to the cyclic fluctuations during the reproductive phase. This imposed, though anticipated, closing of the reproductive chapter of life is often associated with mixed feelings.

As reviewed by Andrea Riccardo Genazzani, MD, PhD, and colleagues, gonadal steroids exercise a profound effect on many body systems, including the brain, in which they have specific receptors, influencing neurotransmitters and other central nervous system (CNS) mechanisms that are considered to be involved in the regulation of mood, cognition, and behavior. Therefore, it would be anticipated that the menopausal decrease in activity levels of female gonadal hormones, ie, estrogen and progesterone, resulting in substantial changes in mood, cognition, and behavior of menopausal women—but this is not the case. This fact illuminates two issues of social and clinical significance: Menopause, per sé, is a normal healthy situation, and even though it is normal it is characterized by age-related processes that may be slowed down or delayed by gonadal steroids.

The etiology and pathophysiology of seasonal affective disorder (SAD) has been linked to the seasons and to light since its first conceptualization. Aspects of SAD that make it particularly amenable to biological investigation include the predictable recurrent episodes, the rapid response to a nonpharmacologic treatment, the specific neurovegetative features, and the availability of rich animal models of seasonality. This paper reviews new findings for the major biological hypotheses for SAD, focusing on circadian rhythms, neurotransmitters, and molecular genetics. Integrative issues and future directions for the study of SAD, including the heuristic value of a dualvulnerability hypothesis that conceptualizes seasonality as a dimensional construct and the importance of studying endophenotypes, will be discussed.

In the same way that a war mobilizes the creative energies of a nation and often leads to major advances in science, technology, and medicine, the terrorist attacks on the World Trade Center and the Pentagon provided a powerful impetus to advance the traumatic stress field. Stung by our inability to provide policymakers with recommendations on evidence-based, early interventions for survivors of the September 11, 2001, attacks, we have been forced to confront the major gaps in our current knowledge.

These gaps are myriad and include our limited understanding of the natural longitudinal course of psychological consequences from the immediate post-impact phase to months and years later. They also include our inadequate scientific understanding of the psychological and psychobiological mechanisms underlying acute and long-term reactions to traumatic events and sparse empirical literature on which to base decisions concerning best practices for interventions. Questions of vulnerability and resilience have taken on a new urgency as we struggle to determine when to respect natural recovery processes and when to provide a formal intervention. With the recognition that there is little empirical justification for psychological debriefing as a one-stop early intervention panacea for the population-at-large has come intensification of efforts to develop and test a variety of novel early interventions that may be suitable for adults and children during the acute aftermath of catastrophic events.

The risks of ischemic stroke, intracerebral hemorrhage, and subarachnoid hemorrhage are not increased in the 9 months of gestation except for a high risk in the 2 days prior and 1 day postpartum. The remaining 6 weeks postpartum also have an increased risk of ischemic stroke and intracerebral hemorrhage, though less than the peripartum period. Although there are some rare causes of stroke specific to pregnancy and the postpartum period, eclampsia, cardiomyopathy, postpartum cerebral venous thrombosis, and, possibly, paradoxical embolism warrant special consideration. The diagnostic and therapeutic approaches to stroke during pregnancy and the postpartum period are similar to the approaches in the nonpregnant woman with some minor modifications based on consideration of the welfare of the fetus. There is a theoretical risk of magnetic resonance imaging exposure during the first and second trimester but the benefit to the mother of obtaining the information may outweigh the risk. Available evidence suggests that low-dose aspirin (<150 mg/day) during the second and third trimesters is safe for both mother and fetus. Postpartum use of low-dose aspirin by breast-feeding mother is also safe for infant. While proper counseling is imperative, a history of pregnancy-related stroke should not be a contraindication for subsequent pregnancy.

The central nervous system is one of the main target tissues for sex steroid hormones, which act on both through genomic mechanisms, modulating synthesis, release, and metabolism of many neuropeptides and neurotransmitters, and through non-genomic mechanisms, influencing electrical excitability, synaptic function, morphological features, and neuron-glia interactions. During the climacteric period, sex steroid deficiency causes many neuroendocrine changes. At the hypothalamic level, estrogen withdrawal gives rise to vasomotor symptoms, to eating behavior disorders, and altered blood pressure control. On the other hand, at the limbic level, the changes in serotoninergic, noradrenergic, and opioidergic tones contribute to the modifications in mood, behavior, and nociception. Hormone replacement therapy (HRT) positively affects climateric depression throughout a direct effect on neural activity and on the modulation of adrenergic and serotoninergic tones and may modulate the decrease in cognitive efficiency observed in climaterium. The identification of the brain as a de novo source of neurosteroids, suggests that the modifications in mood and cognitive performances occurring in postmenopausal women may also be related to a change in the levels of neurosteroids. These findings open new perspectives in the study of the effects of sex steroids on the central nervous system and on the possible use of alternative and/or auxiliary HRT.

Following the introduction of lamotrigine in 1994 as a treatment for epilepsy in the United States, the drug has seen progressively greater application in psychiatry, particularly as a treatment for bipolar disorder. This review critically evaluates the support for lamotrigine use across a broad range of psychiatric disorders as well as discuss its pharmacology, side-effect profile, and interactions with other medications.

Since their introduction 50 years ago, antidepressants have been used in a wide variety of settings involving gastrointestinal (GI) disease. In the 1950s, antidepressants were shown to have some efficacy for the treatment of peptic ulcer disease. This is most likely due to their antihistaminic and anticholinergic effects. Since then, more efficacious and more disease-specific treatments have become available. In the last 20 years, antidepressants have been increasingly used for the treatment of functional gastrointestinal disorders such as irritable bowel syndrome, noncardiac chest pain, and other functional GI disorders. This article will review the rationale for the use of antidepressant drugs for the treatment of functional GI disorders. The role of psychiatric comorbidity in functional GI disorders, the impact of antidepressants on GI motility and visceral sensation, and the ability of these agents to produce improvements in the global well-being and overall quality of life will be reviewed. Finally, guidelines for prescribing and barriers to a patient's acceptance of these agents will be discussed.

Bright light therapy for seasonal affective disorder (SAD) has been investigated and applied for over 20 years. Physicians and clinicians are increasingly confident that bright light therapy is a potent, specifically active, nonpharmaceutical treatment modality. Indeed, the domain of light treatment is moving beyond SAD, to nonseasonal depression (unipolar and bipolar), seasonal flare-ups of bulimia nervosa, circadian sleep phase disorders, and more. Light therapy is simple to deliver to outpatients and inpatients alike, although the optimum dosing of light and treatment time of day requires individual adjustment. The side-effect profile is favorable in comparison with medications, although the clinician must remain vigilant about emergent hypomania and autonomic hyperactivation, especially during the first few days of treatment. Importantly, light therapy provides a compatible adjunct to antidepressant medication, which can result in accelerated improvement and fewer residual symptoms.

Objective: In multiple sclerosis (MS), magnetic resonance imaging (MRI) predictors of cognitive impairment are based on sophisticated computer-generated analyses that are difficult to apply in clinical settings. This study investigated the clinical usefulness of a new visual rating scale, the Cholinergic Pathways Hyperintensities Scale (CHIPS), in detecting cognitive dysfunction.

Methods: Forty clinically definite MS patients underwent a brain MRI. Based on the CHIPS, cholinergic pathway hyperintensities were rated in 10 regions on four axial slices. Computerized hyperintense lesion volumes were also obtained. For cognitive testing, The Neuropsychological Screening Battery for Multiple Sclerosis was used. “Low” and “High” lesion score groups were computed based on the mean of the total CHIPS score. Optimal sensitivity and specificity of the total CHIPS score in detecting cognitive impairment were determined using a receiver operator characteristic curve.

Results: Despite a similar demographic profile, subjects with a “High” lesion score performed significantly worse than the “Low” lesion score group on verbal (P=.007) and visuospatial (P=.02) memory, and on a global index of cognitive functioning (P=.001). Optimal sensitivity (82%) and specificity (83%) were reached with a threshold total CHIPS score of 18 points. Total CHIPS score and total hyperintense lesion load were correlated (σ=0.82, P<.0001).

Conclusion: CHIPS is helpful in clinically predicting cognitive impairment in MS.
