Abstract
Stroke is the leading cause of human death and disability. After a stroke, many patients may have some physical disability, including difficulties in moving, speaking, and seeing, but patients may also exhibit changes in mood manifested by depression, anxiety, and cognitive changes which we call post-stroke mood disorders (PSMDs). Astrocytes are the most diverse and numerous glial cell type in the central nervous system (CNS). They provide structural, nutritional, and metabolic support to neurons and regulate synaptic activity under normal conditions. Astrocytes are also critically involved in focal ischemic stroke (FIS). They undergo many changes after FIS. These changes may affect acute neuronal death and brain damage as well as brain recovery and PSMD in the chronic phase after FIS. Studies using postmortem brain specimens and animal models of FIS suggest that astrocytes/reactive astrocytes are involved in PSMD. This chapter provides an overview of recent advances in the molecular base of astrocyte in PSMD. As astrocytes exhibit high plasticity after FIS, we suggest that targeting local astrocytes may be a promising strategy for PSMD therapy.

Abstract
Neurological disease can impair emotional communication by several means: damaging the networks important in understanding the meaning of emotional stimuli (emotional semantics); damaging networks important in the perceptual recognition and production of emotional stimuli, and damaging the connections between networks supporting emotional semantics and recognition/production networks. Disorders of emotional expression, comprehension, and emotional semantics may improve with pharmacological or behavioral treatments. Pharmacological treatments can be used to redress naturally occurring or disease-related alterations in the computational properties of target neural systems. No drug treatment can replace a loss of cerebral knowledge related to the pathological loss of neural connectivity. Behavioral treatments that benefit either comprehension or expression of specific emotions may be of value if these emotions are particularly important in enabling human social interaction. However, behavioral treatments that achieve generalization, that is, improve performance with untrained exemplars and in daily life, are much to be preferred, even as they pose the greatest methodological challenges. This chapter will discuss possible mechanisms of generalization and then review what is known about the treatment of expressive and receptive affective aprosodia, deficits in recognition of facial emotions, and pseudobulbar affect. The final section of the chapter is devoted to a discussion of three disorders of emotional semantics, apathy, alexithymia, and impaired empathy.

Abstract
OBJECTIVE To examine the validity of factor analytically based summary scores that were developed using the National Institutes of Health Toolbox Emotion Battery (NIHTB-EB); (ie, psychological well-being, social satisfaction, negative affect) normative sample in individuals with neurologic conditions. DESIGN Cross-sectional, observational cohort. SETTING Community. PARTICIPANTS A total of 1036 English-speaking adults from the National Institutes of Health Toolbox (NIHTB) normative project and 604 community-dwelling adults with neurologic conditions including spinal cord injury (SCI n=209), traumatic brain injury (TBI n=184), and stroke (cerebrovascular accident [CVA] n=211) (N=1640). INTERVENTION Not applicable. MAIN OUTCOME MEASURES The NIHTB-EB. RESULTS A series of univariate analyses comparing summary scores across the 4 groups (SCI, TBI, CVA, normative group) were conducted to identify group differences. Base rates (defined as >1 SD toward the problematic direction) were also identified. The normative group demonstrated better emotional functioning characterized by greater social satisfaction and psychological well-being (normative group > SCI, TBI, CVA; P's <.0001), and less negative affect (normative group < SCI, P=.016; normative group < TBI, P<.001; normative group < CVA; P=.034) compared with each neurologic group. Using base rates to identify problematic emotions for the 3 summary scores, there were higher rates of problematic emotions on all 3 summary scores for the neurologic groups compared with the normative group. CONCLUSIONS The NIHTB-EB summary scores demonstrate an increased prevalence of problematic emotions among individuals with 3 neurologic conditions, and might be useful for identifying individuals with similar conditions and potentially in need of psychological support.

Abstract
PURPOSE To determine if it is possible to successfully treat pseudobulbar affect (PBA) using a behavioral approach. DESIGN AND METHODS Two experiments were conducted, each a double reversal design with the same single subject in both. The first experiment tested the hypothesis that the rate of PBA could be controlled by manipulation of its consequences. The second experiment tested the hypothesis that use of a self-control procedure would control the rate of PBA. FINDINGS Rate of PBA could not be controlled by consequence manipulation, but rate of PBA could be controlled through use of a self-control procedure. PRACTICE IMPLICATIONS Pending confirmatory research, behavioral interventions utilizing self-control procedures should be considered in patients with PBA.

Abstract
Dextromethorphan (DM) is a commonly used antitussive and is currently the only FDA-approved pharmaceutical treatment for pseudobulbar affect. Its safety profile and diverse pharmacologic actions in the central nervous system have stimulated new interest for repurposing it. Numerous preclinical investigations and many open-label or blinded clinical studies have demonstrated its beneficial effects across a variety of neurological and psychiatric disorders. However, the optimal dose and safety of chronic dosing are not fully known. This review summarizes the preclinical and clinical effects of DM and its putative mechanisms of action, focusing on depression, stroke, traumatic brain injury, seizure, pain, methotrexate neurotoxicity, Parkinson's disease and autism. Moreover, we offer suggestions for future research with DM to advance the treatment for these and other neurological and psychiatric disorders.

Abstract
OBJECTIVES Characterize the prevalence and impact of crying and tearfulness as symptoms that may be suggestive of pseudobulbar affect (PBA) in residents of nursing facilities, including those with Alzheimer's disease (AD) and non-AD [non-AD-associated] associated dementia. DESIGN Data were extracted retrospectively from a large repository of de-identified and linked Minimum Data Set 2.0 (MDS) and prescription claims records for the period between October 1, 2009, and September 30, 2010. A score of 1 or 2 on MDS item E1m ("crying, tearfulness") was used to identify potential PBA. SETTING 19,000 nursing facilities in 48 states. PATIENTS/PARTICIPANTS Prescription and MDS records of nursing facility residents. MAIN OUTCOME MEASURES Comparison of concomitant diagnoses, MDS mood, and behavioral indicators, and psychopharmacologic medication use, in residents with crying/tearfulness to a control group matched for age, gender, diagnosis of AD or non-AD dementia, and diagnosis of depression. RESULTS A total of 137,829 residents underwent at least one MDS assessment during the study period. Of these, 12,595 (9.1%) had item E1m ("crying, tearfulness") scored as a 1 or 2 on their MDS assessments. Ten thousand residents were then randomly selected from this group and matched to 10,000 controls without "crying, tearfulness" (MDS E1m = 0) for analysis. A total of 4,786 (47.9%) unique residents with "crying, tearfulness" had a diagnosis of AD (8.8%), non-AD dementia (31.5%), or both (7.6%). All of the MDS mood indicators were at least twice as prevalent in this group compared with those without "crying, tearfulness" Additionally, mood symptoms such as anger, worried/pained facial expressions, and repetitive verbalizations; and behavioral symptoms such as verbal/physical abuse and socially inappropriate/disruptive behavior, were more than twice as frequent in the "crying, tearfulness" group. Antipsychotic medications were also used more often in this group (50% vs. 36.1%), as were antidepressants (59.1% vs. 49.8%). CONCLUSIONS In the absence of an International Classification of Diseases 9th edition, Clinical Modification code, the presence of "crying, tearfulness" on MDS 2.0 item E1m was used as a proxy to identify potential PBA. Nursing facility residents with "crying, tearfulness" had a higher prevalence of all mood and behavior indicators as well as psychopharmacological medication use, compared with matched controls without "crying, tearfulness." Similar results were seen in the subgroup of residents with an underlying diagnosis of AD and/or non-AD dementia. Further research should validate the actual prevalence of PBA in this population, and the corresponding impact on resident outcomes.

Abstract
Pseudobulbar affect (PBA) is defined by episodes of involuntary crying and/or laughing as a result of brain injury or other neurological disease. Epidemiology studies show that 5.3%-48.2% of people with traumatic brain injury (TBI) may have symptoms consistent with (or suggestive of) PBA. Yet it is a difficult and often overlooked condition in individuals with TBI, and is easily confused with depression or other mood disorders. As a result, it may be undertreated and persist for longer than it should. This review presents the signs and symptoms of PBA in patients with existing TBI and outlines how to distinguish PBA from other similar conditions. It also compares and contrasts the different diagnostic criteria found in the literature and briefly mentions appropriate treatments. This review follows a composite case with respect to the clinical course and treatment for PBA and presents typical challenges posed to a provider when diagnosing PBA.

Abstract
BACKGROUND Brain injury from stroke and traumatic brain injury (TBI) may result in a persistent neuroinflammatory response in the injury penumbra. This response may include microglial activation and excess levels of tumour necrosis factor (TNF). Previous experimental data suggest that etanercept, a selective TNF inhibitor, has the ability to ameliorate microglial activation and modulate the adverse synaptic effects of excess TNF. Perispinal administration may enhance etanercept delivery across the blood-CSF barrier. OBJECTIVE The objective of this study was to systematically examine the clinical response following perispinal administration of etanercept in a cohort of patients with chronic neurological dysfunction after stroke and TBI. METHODS After approval by an independent external institutional review board (IRB), a chart review of all patients with chronic neurological dysfunction following stroke or TBI who were treated open-label with perispinal etanercept (PSE) from November 1, 2010 to July 14, 2012 at a group medical practice was performed. RESULTS The treated cohort included 629 consecutive patients. Charts of 617 patients following stroke and 12 patients following TBI were reviewed. The mean age of the stroke patients was 65.8 years ± 13.15 (range 13-97). The mean interval between treatment with PSE and stroke was 42.0 ± 57.84 months (range 0.5-419); for TBI the mean interval was 115.2 ± 160.22 months (range 4-537). Statistically significant improvements in motor impairment, spasticity, sensory impairment, cognition, psychological/behavioural function, aphasia and pain were noted in the stroke group, with a wide variety of additional clinical improvements noted in individuals, such as reductions in pseudobulbar affect and urinary incontinence. Improvements in multiple domains were typical. Significant improvement was noted irrespective of the length of time before treatment was initiated; there was evidence of a strong treatment effect even in the subgroup of patients treated more than 10 years after stroke and TBI. In the TBI cohort, motor impairment and spasticity were statistically significantly reduced. DISCUSSION Irrespective of the methodological limitations, the present results provide clinical evidence that stroke and TBI may lead to a persistent and ongoing neuroinflammatory response in the brain that is amenable to therapeutic intervention by selective inhibition of TNF, even years after the acute injury. CONCLUSION Excess TNF contributes to chronic neurological, neuropsychiatric and clinical impairment after stroke and TBI. Perispinal administration of etanercept produces clinical improvement in patients with chronic neurological dysfunction following stroke and TBI. The therapeutic window extends beyond a decade after stroke and TBI. Randomized clinical trials will be necessary to further quantify and characterize the clinical response.

Abstract
Correct diagnosis of acute stroke is of paramount importance to clinicians to enable selection of correct treatments and to ensure prevention of acute complications, including recurrent stroke. Timely diagnosis can be difficult in some cases because patients with acute stroke can present with atypical or uncommon symptoms that suggest another cause altogether. Publications on these patients suggest that the following strategies could help to reduce misdiagnosis. First, clinicians should suspect stroke in any patient with abrupt onset of neurological symptoms. Second, clinicians should be aware that some patients will initially present with various uncommon and atypical stroke symptoms. Third, a complete and systematic neurological examination should be routinely done in patients presenting with acute neurological symptoms because this might shed light on the true nature of the problem. Finally, clinicians should be aware that even with the most sophisticated neuroimaging tests, stroke might be missed in the early hours after the event.
