Table 1. Information regarding patients, treatment details including management strategy and duration of resolution with follow-up periods. Analysis of the cases A careful history and physical examination revealed that all of the patients had their regular menstrual cycle before these events of amenorrhea. There was no evidence of recent weight gain or loss and no history of eating disorder or excessive athletic activities. There was no previous contributing

medical or family history of any other possible hereditary, traumatic, surgical, metabolic, infective, organic or pathologic diseases. None of the patients were smokers, alcoholic, or diabetic. Further meticulous clinical and physical examinations Inhibitors,research,lifescience,medical were negative for other psychiatric illnesses, surgeries, or substance abuse.

Inhibitors,research,lifescience,medical The vital signs of all five patients were essentially within normal limits. The first four out of five patients were sexually active and were continuously on oral contraceptive pill (OCP). Hence, sudden withdrawal of oral contraceptives cannot be implicated as a likely cause of their amenorrhea. The fifth patient denied taking any OCPs. None of patients reported any hot flushes, severe headaches, or visual field disturbances. Examination of the breasts Inhibitors,research,lifescience,medical of the first, second, and fourth patients revealed no secretions or tenderness. In the case of patients three and five, bilateral breast secretion could be expressed without any tenderness or dimpling. Skin examination of patients three and five showed mild papular acne on their faces and mild hair Inhibitors,research,lifescience,medical growth on their chins. There was evidence for mild painful pustular lesion on back of the fifth patient. There were no abnormalities in their routine blood chemistry, liver function tests, or renal function tests. Routine electrolyte and urine analysis were essentially within normal limits. The first, second, and fourth patients had mild elevated serum prolactin levels without any selleck kinase inhibitor associated physical signs and symptoms. However, the

Inhibitors,research,lifescience,medical third and fifth patients had substantially higher serum prolactin levels. During systemic evaluation, preliminary exclusion of potential causes of secondary amenorrhea and hyperprolactinemia such as adenopathy, celiac disease, hypergonadism, polycystic ovary syndrome (PCOS), primary ovary insufficiency, Turner syndrome, see more Asherman’s syndrome, and insulin sensitivity studies were done by correlating their hormonal levels, past and present menarche histories and associated physical findings followed by expert opinions from respective fields. The pertinence of the above preliminary findings was further evidenced by unremarkable pelvic examinations, pelvic ultrasounds, magnetic resonance imagining (MRI) scans (focused on the brain and particularly the pituitary gland), hysterosalpingographies (HSG), and mammography tests.

3 years (Standard deviation (SD) 2.1 years), similar to the pre-immunisation survey (19.2 years, SD 2.4 years). There were fewer specimens from community sexual health services in the post-immunisation period (3.1% vs. 24.0% pre-immunisation), which was the venue with the highest HR HPV prevalence in 2008 (with inhibitors relatively more from youth clinics

post-immunisation). The proportion of women with missing information on sexual behaviour increased between the two surveys but there was no change in the reported data with around half of respondents reporting two or more sexual partners in the previous year and a new sexual partner in the previous 3 months. The specimens were broadly representative, in terms of reported sexual behaviour data, of all Crizotinib chlamydia screens reported to PHE for females at the selected venues. Relatively high chlamydia positivity was seen amongst specimens from two laboratories selleck compound (Leeds 26.4%, Lewisham 7.2%, vs. 4.7% at all other laboratories combined) but no reason could be identified for systematic selection bias. The estimated HPV vaccine coverage was 65% for subjects aged 16–18 years, 30% for those 19–21 years and 0% for those 22–24 years. The prevalence of HPV 16 and/or 18 in the post-immunisation survey was lowest in 16–18 year olds, at 6.5% (95% CI: 5.2–8.0%) (Fig. 2). Prevalence increased

with age to 12.5% in 19–21 year olds and 18.6% in 22–24 year olds (p-value for trend <0.0001). In contrast in 2008, the prevalence was highest in 16–18 year olds (19.1%, 95% CI: 16.6–21.8%) and lower at older ages (14.8%, 95% CI: 11.9–18.3% in 22–24 year olds). The 19–21 year olds in the post-immunisation survey (2010–2012) included females eligible and not eligible for immunisation: both these groups had lower HPV prevalence than found pre-immunisation. Females

who were in birth-cohorts eligible for vaccination had a lower prevalence of HPV 16/18 (10.9% [95% CI: 9.2–12.9%]) than those who were not eligible for vaccination (15.3% [95% CI: 11.7–19.7%]), p-value = 0.036. There was no sign of any reduction amongst females aged 22–24 years. There were significant differences in the reduction of prevalence for different ethnic groups; among MYO10 white women the prevalence of HPV 16/18 infection in 16–18 year olds reduced from 19.7% to 6.7% (66%) in pre- vs. post-immunisation surveys whereas for black women this reduction was less marked (and not significant) from 14.9% to 9.4% (37%). There were too few individuals of Asian and other ethnic origin for formal comparison. The adjusted odds ratio for HPV 16/18 infection comparing the post-immunisation period with the pre-immunisation was 0.3 (95%CI: 0.2–0.5) for 16–18 year olds and increased with age (Table 2) as would be expected as a reflection of vaccine coverage and age of immunisation (p-value for heterogeneity <0.0001).

Univariate analysis Univariate analysis will be performed to determine the strength of association between the predictor variables and serious outcomes. We will choose the appropriate univariate technique based on the type of data: chi square test with continuity correction for nominal variables; unpaired, two tailed t-test for continuous

variables, using pooled or separate variance estimate Inhibitors,research,lifescience,medical as appropriate; and, the Mann–Whitney U test for ordinal variables. For continuous variables we will assess for the most discriminative cut point to include in multivariate analysis. Multivariate analysis Variables that are reliable (kappa ≥0.6) and strongly Epacadostat chemical structure associated with serious outcomes (p-value <0.2) will be selected for

multivariate analysis by logistic regression using Statistical Analysis System (SAS) software or using recursive partitioning. We will use multivariate analysis to identify the risk factors for serious outcomes within 30 days of ED discharge and to derive a clinical decision tool. When building the model, for Inhibitors,research,lifescience,medical missing predictor variables, we plan to either impute Inhibitors,research,lifescience,medical by multiple imputations or assume as normal if it is in young patients with obvious vasovagal syncope [58]. We will evaluate interaction among predictor variables using Mantel-Haenszel and logistic model procedures. We will consider appropriate combining of variables and use composite variables for incorporation (e.g. bifascicular block). We will assess Inhibitors,research,lifescience,medical for multicolinearity in the model, a statistical phenomenon in which two or more predictor variables are highly correlated. We will also assess for lack of fit

by Hosmer-Lemeshow goodness-of-fit test and for overfitting in the model by Akaike information criterion [59,60]. If difficulties arise in developing a clinical decision tool with acceptable diagnostic test characteristics, we will explore the option of building models Inhibitors,research,lifescience,medical with separation of serious events: before and after the 7-day mark; detection of serious underlying conditions (serious structural heart disease, aortic dissection, pulmonary embolism, severe pulmonary hypertension, subarachnoid hemorrhage or significant hemorrhage) versus prediction of serious events (arrhythmia or death); separation of cardiac versus non-cardiac events; and excluding patients with procedural interventions performed without evidence of underlying Casein kinase 1 serious condition (e.g. pacemaker insertion without evidence of bradyarrhythmia). If there is considerable variation in the ED length of stay among the study patients, we will also explore the option of the primary outcome as occurrence of serious outcome 6 hours after ED arrival. The majority of syncope patients are assigned a Canadian Triage and Acuity Scale (CTAS) 3. As a result, in most Canadian provinces it is expected that a disposition decision is made within six hours of arrival. Hence, we will choose a 6 hour cut off point if needed.

Given the stoichiometry of ion coupling to glutamate uptake, the theoretical lower limit of extracellular glutamate in brain is approximately 2 nM (Zerangue and Kavanaugh, 1996 and Levy et al., 1998). Many studies using intracerebral microdialysis have reported levels of ambient glutamate ⩾ 2 μM, three orders of magnitude higher than the theoretical lower limit (Benveniste et al., 1984 and Lerma et al., 1986; for reviews see Cavelier et al., 2005 and Nyitrai et al., 2006). By contrast, reports of ambient glutamate concentration estimated from electrophysiological

measurement of tonic NMDA receptor activity in hippocampal slice selleck chemical range from 87 to 89 nM (Cavelier and Attwell, 2005 and Le Meur et al., 2007) to as low as 25 nM (Herman and Jahr, 2007). Accurate knowledge of the ambient glutamate concentration in different brain selleck kinase inhibitor regions is important for evaluating its effects on synaptic transmission. Several ionotropic and metabotropic glutamate receptor subtypes are activated by low micromolar concentrations of glutamate, and tonic exposure in this range profoundly inhibits synaptic circuitry in vitro ( Zorumski et al., 1996). Glutamate transporters play a dominant role in limiting ambient glutamate, as pharmacological

inhibition of transport has been shown to lead to a rapid increase in ambient glutamate causing increased tonic NMDA receptor signaling ( Jabaudon et al., 1999, Cavelier and Attwell, 2005, Le Meur et al., 2007 and Herman and Jahr, 2007). In this work we attempt to integrate data in the literature with new in vitro measurements and in vivo modeling of diffusion gradients formed by glutamate transporters. Proceeding from the assumption that in steady-state conditions, the volume-averaged rates of release and uptake of glutamate are equal, we

show the influence of glutamate transporter membrane density on steady-state diffusion gradients in a density range relevant to in vivo brain expression. We suggest that Libraries metabolic impairment of glutamate transport in a shallow boundary region of a microdialysis probe can account for the discrepancies between estimates of ambient glutamate from dialysis and electrophysiological approaches. Approximately 50 ng of human EAAT3 cRNA was microinjected into stage V–VI Xenopus oocytes and recordings Tolmetin were made 1–6 d later. Recording solution contained 96 mM NaCl, 2 mM KCl, 1 mM MgCl2, 1.8 mM CaCl2, and 5 mM Hepes (pH 7.5). Microelectrodes were pulled to resistances between 1 and 3 MΩ and filled with 3 M KCl. Data were recorded with Molecular Devices amplifiers and analog–digital converters interfaced to Macintosh computers. Data were analyzed offline with Axograph X (v.1.0.8) and KaleidaGraph (v 3.6; Synergy) software. For stopped flow measurements, oocytes were voltage clamped at −60 mV in a perspex recording chamber in which glutamate depletion in the absence of perfusion was <1% of the total in the recording chamber.

2). Negative motivation (Neg > Neut-N) resulted in greater bilateral VS, left ventral tegmental area, right fusiform gyrus, and left MOG activation when contrasted with its corresponding neutral condition (Table ​(Table2).2). There

were no significant differences between the neutral conditions (Neut-N > Neut-P and Neut-P > Neut-N). Table 2 Effect of motivation on BOLD activity: fMRI whole-brain analysis Correlation between change in response bias and Inhibitors,research,lifescience,medical brain activation Region-of-interest analyses revealed that the shift to a more liberal response bias in the positive motivation condition (ΔcPositive) correlated with increased activation in the left IFG pars triangularis (MNI coordinates: x, y, z: −42, 14, 19; r = −0.67, pFWE < 0.05) (Pos > Neut-P) (Fig. ​(Fig.3A3A and B). Similarly, in the negative motivation condition, increased Inhibitors,research,lifescience,medical activation in the left IFG pars triangularis (MNI coordinates: x, y, z: −33, 29, 4; r = −0.62, pFWE < 0.05) (Neg > Neut-N) correlated with the liberal shift in response bias (ΔcNegative) (Fig. ​(Fig.3C3C and D). Whole-brain analyses did not identify

any additional regions. Figure 3 Correlation between the change in response bias and activation in the left IFG. The larger the shift toward a liberal response bias (Δc), the greater the left IFG activation for both the Pos compared to Neut-P (A & B) and Neg compared … Discussion Using response Inhibitors,research,lifescience,medical bias as a measure for decision criterion and altering it by manipulating motivation in a perceptual decision-making task, the left IFG was identified as a possible response bias regulating region. This PLX4032 nmr region met Inhibitors,research,lifescience,medical the two criteria we established a priori: BOLD activity correlated with the change in bias from the neutral to the motivated conditions, and this relationship held true regardless of whether positive or

negative motivation induced the shift in response bias. In line with previous findings (Henriques et Inhibitors,research,lifescience,medical al. 1994; Reckless et al. 2013), motivation resulted in the adoption of a more liberal response bias compared Tolmetin to when less motivated. There was, however, no motivation mediated increase in detection sensitivity. While the absence of such a relationship is in keeping with results from a study using a similar paradigm (Reckless et al. 2013), it is contrary to other perceptual decision-making studies that suggest a positive, linear relationship between motivation and increased performance (Engelmann and Pessoa 2007; Engelmann et al. 2009). These studies, however, used a discrimination task while this study used a detection task. Still, the absence of a relationship between motivation and performance draws into question whether the flexibility in decision-making observed in this study was actually adaptive. Response bias, however, was mathematically more optimal in the motivated conditions.

Coupling of the somatostatin receptor type 2 agonist to irinotecan-loaded liposomes improved their antitumor activity in a medullary thyroid

carcinoma model [105]. Its coupling to PEGylated doxorubicin-loaded liposomes led to superior doxorubicin accumulation in tumors and enhanced anticancer efficacy against small cell lung cancer tumors compared to untargeted liposomes [106]. Han and coworkers selected a peptide (HVGGSSV) by phage display which selectively bound to the tumor vasculature of tumors that were regressing after radiotherapy, while no binding was detected before irradiation or in areas of tumor necrosis factor alpha-induced inflammation in mice [140]. They proposed the peptide Inhibitors,research,lifescience,medical Inhibitors,research,lifescience,medical that recognized a protein displayed only on tumor endothelial cells that were responding to therapy. Interestingly, they conjugated this peptide to the surface of doxorubicin-loaded liposomes for “radiation-guided tumor-targeted drug delivery” [141]. SCH772984 supplier higher tumor accumulation of doxorubicin was achieved with targeted liposomes after irradiation over untargeted doxorubicin-loaded liposomes with or without irradiation

and resulted in higher therapeutic Inhibitors,research,lifescience,medical efficacy in both Lewis lung carcinoma and non-small cell lung carcinoma (HL460) tumors. Identification of a non-small cell lung cancer-specific peptide also identified by phage display to doxorubicin or vinorelbine-loaded PEGylated liposomes enhanced

drug distribution to tumors and resulted in increased therapeutic efficacy over untargeted Inhibitors,research,lifescience,medical drug-loaded liposomes [38]. Another group reported higher therapeutic efficacy against lung cancer xenografts of PEGylated doxorubicin-loaded liposomes conjugated with a large-cell cancer-specific peptide over untargeted doxorubicin-loaded liposomes [142]. Breast cancer-specific peptide/phage fusion coat protein pVIII chimeras have been used for tumor-targeted drug delivery Inhibitors,research,lifescience,medical [143, 144]. Membranophilic major phage coat protein pVIII fused with a targeting peptide identified by phage display spontaneously inserts into liposomes. The insertion of a breast cancer-specific phage fusion protein into doxorubicin-loaded liposomes (Doxil) led to an increased binding to breast tumor cells and enhanced cytotoxicity over untargeted Doxil liposomes in vitro [143, 144]. This is noteworthy, since no chemical conjugation step Non-specific serine/threonine protein kinase is involved, this method allows fast and selective identification of tumor ligands. PEGylated paclitaxel-loaded liposomes harboring a synthetic luteinizing hormone-releasing hormone (LHRH) peptide designed to interact with the LHRH receptors that are overabundant in the membrane of cancer cells [145] showed increased tumor accumulation and therapeutic efficacy over untargeted paclitaxel-loaded liposomes [107].

These trans-acting factors recruit HATs to the target gene resulting in increased histone acetylation, chromatin opening, and increased accessibility of the DNA to demethylases. Since methylation of cytosine is an extremely stable chemical bond on DNA, this modification will

remain stable for years. For methylation signals to serve as stable markers, they should Inhibitors,research,lifescience,medical not be responsive to transient chromatin noise or short-term signals. The mechanism proposed here also allows for a reversal of the methylation marker by a similar intense change in chromatin structure later in life.99,110 This model has important implications on our understanding of how environmental signals, such as variations in maternal care, might stably alter glucocorticoid gene expression. DNA methylation marks genes for silencing by a number of mechanisms. The first mechanism is indirect and links DNA methylation to inactive chromatin structure. A region of methylated DNA juxtaposed

to regulatory regions of genes attracts different members of a family of methylated DNA Inhibitors,research,lifescience,medical binding proteins, such as methylCpG-binding protein, MeCP2, which recruits HDACs105,106 and histone methyltransferases111 to methylated genes.91,112 This results in a modification of chromatin around the gene precipitating an inactive chromatin structure. A different mechanism, which is relevant to our discussion Inhibitors,research,lifescience,medical here, involves direct interference of a specific methylated CpG residing within a response element for a transcription factor with the interaction of a transcription Inhibitors,research,lifescience,medical factor, such as the inhibition of binding of cMyc to its response element when it is methylated.113 Essentially,

the methylated cytosine serves as a mutation of the recognition element, functionally reducing the binding affinity of the response element for its transcription factor. A third mechanism involves a combination of binding of a methylated DNA binding protein and inhibition of activity of a transcription factor.114 While the first mechanism is dependent on the general density of methyl cytosines within the region associated with a gene rather than Inhibitors,research,lifescience,medical methylation of a specific CpG, the second mechanism requires a discrete methylation event and is relevant to the PD184352 (CI-1040) mechanism proposed here. The important consideration is the stability of cytosine methylation, which is preserved by covalent carbon-carbon bonds and could therefore serve as a long-term genomic “memory” of early experience influencing chromatin structure and GR expression in offspring of highand low-LG mothers. GR gene expression is increased throughout the hippocampus in the adult offspring of high-LG compared with low-LG mothers.39 The exon 17 GR promoter sequence appears to be significantly more active in the adult offspring of high-LG compared with low-LG mothers and was therefore the focus of ZD1839 purchase initial studies of possible maternal effects on DNA methylation.

It is incumbent upon the member to update this disclosure should his/her personal situation change. Members, representatives and consultants are expected to conduct themselves in an appropriate manner and in accordance with the NACI guidelines. In situations where a conflict of interests or the appearance thereof inhibitors arises in the course of the work of the committee,

the individual involved must declare its existence and either work with the Executive Secretary to resolve the this website conflict, or if necessary, disqualify himself/herself from participation in the discussion or from further participation on the committee according to the circumstances of specific situations. In January 2009, NACI formally introduced its process to develop and grade evidence-based recommendations through the publication of its Statement: “Evidence-based recommendations for immunization—Methods

of the National Advisory Committee on Immunization” (available at: http://www.phac-aspc.gc.ca/publicat/ccdr-rmtc/09vol35/acs-1/index-eng.php). Publication of this process is intended to provide a transparent and clear description Selleck Ku-0059436 of the methods used for retrieving, synthesizing and weighing evidence that leads to a NACI recommendation. In brief, the stages for the development of NACI recommendations are: 1. Knowledge synthesis (retrieval and summary of individual studies on vaccine safety, efficacy, immunogenicity, effectiveness, ranking of the level and quality of evidence of each study). The relevant NACI Working Group is responsible for establishing the scope of and requirements for the literature review. Ketanserin The literature review may be contracted out to an external group/consultant, or performed within the PHAC. As part of the literature review, evidence tables are assembled in which each study is assigned a level of evidence based on research design (e.g. Level I for evidence from randomized controlled trials) and an assessment of the quality (internal validity) of the study is made (i.e. Good, Fair, Poor-based on design-specific criteria as outlined in Harris et

al., 2001 [4]). The full knowledge synthesis includes a review of the product monograph, scientific literature on the burden of disease (epidemiology, morbidity, mortality) in the population in general and in specific risk groups, vaccine characteristics (e.g. safety, immunogenicity, efficacy, effectiveness), in addition to various scientific factors outlined in “An Analytic Framework for Immunization Programs in Canada” [5]. Recommendations from other groups (e.g. WHO, Advisory Committee on Immunization Practices, Canadian Pediatric Society) are reviewed. The Working Group prepares recommendation options for consideration by the full NACI committee. The Medical Lead and the NACI Working Group Chair review all individual studies, but all the assembled evidence is available to the Working Group and to NACI.

Few studies examined the influence of antipsychotic medications, and most, studies could not find a significant influence of medications in EMG recordings. However, a recent, study33 reported less zygomatic activity in unmedicated patients than in NCSs, and a decrease in smiling activity when IWSs were treated with risperidone, but, not with olanzapine. Autonomic nervous system Some physiological Inhibitors,research,lifescience,medical manifestations

of emotions, such as increased heart, rate, Fluorouracil cost perspiration, hot face, faster respiration, dry mouth, and increased urination are expressed through the ANS. Although some authors reported emotion-specific ANS response patterns, replications did not follow, and emotion-specific ANS response patterns have been considered as unreliable. Skin conductance. Skin conductance Inhibitors,research,lifescience,medical has been the most frequently physiological measure used to evaluate ANS response to emotions. Skin conductance is under sympathetic control, is correlated with the number of eccrine sweat glands, and is sensitive to a large range of stimuli, Inhibitors,research,lifescience,medical including emotional arousal.3-1 Compared with NCSs, IWSs showed similar (four studies) or higher (one study) skin conductance reactivity in positive conditions,

and similar (five studies) or higher (two studies) skin conductance reactivity in negative conditions. It should be noted that IWSs have shown more skin conductance reactivity even with neutral stimuli in two studies.31,35 A thorny issue concerns medication status. Acetylcholine, norepinephrine, and dopamine are Inhibitors,research,lifescience,medical neuromediators involved in the ANS,36 and it has been shown that antipsychotic medications have an impact on skin conductance. Therefore, it, has been thus recommended to conduct psychophysiological studies with unmedicated patients only. Among the studies just reviewed above, only two used unmedicated Inhibitors,research,lifescience,medical patients, and one of them37 reported a higher skin conductance for positive and negative conditions. Cardiovascular system. Other studies32,38-40 looked at cardiovascular reactivity (heart rate and blood volume)

to emotional stimuli. The results have been mixed. Some studies found no differences between groups, a decreased finger pulse volume reactivity, or different time-response curves for heart rate variability in schizophrenia. Conclusions: emotion expression It thus appears that expression studies in schizophrenia research can be divided into two broad categories: emotion expressiveness and emotion reactivity. Fossariinae Emotion expressiveness includes controlled expressions with an intentional component and their social, communicative value is evident. Expressiveness encompasses verbal output, and overt facial expressions. Emotion reactivity contains an idea of automaticity or covert, expressions. Covert facial muscle activity and ANS reactions can be placed in this category. IWSs show deficits in emotion expression in verbal, facial, and acoustic channels.

57 Schizophrenia spectrum disorders There is an emerging formulation from several laboratories that schizophrenia is part of a larger set of disorders called schizophrenia spectrum disorders or schizotaxia; these disorders are related to each other in terms of genetics, symptom expression, cognitive characteristics, and, potentially, pathophysiology. Schizophrenia itself may be the most severe manifestation of the class and Inhibitors,research,lifescience,medical characterized by the most flagrant psychosis and the worst psychosocial

function (Figure 1). But impairment at multiple levels and schizophrenialike symptoms span the entire spectrum group. Approximately 20% of family members of an individual with schizophrenia have spectrum manifestations. Moreover, approximately 20% of persons with spectrum Inhibitors,research,lifescience,medical manifestations have symptoms that are severe enough to impair work function and may benefit from antipsychotic treatment (G. Thaker, personal communication). Figure 1. Schizophrenia spectrum disorders. The prevalences of schizophrenia and schizophrenia-related personality disorders in the www.selleckchem.com/products/umi-77.html general population are 1% and 5%, respectively; the prevalence of both together is 6%. First-degree relatives of schizophrenic probands may display many of the cognitive symptoms characteristic of schizophrenia, only without the florid psychosis. These include task-related impairments in attention,

language Inhibitors,research,lifescience,medical comprehension, verbal fluency, verbal memory, and spatial working memory. It is suspected that these cognitive disturbances in relatives Inhibitors,research,lifescience,medical occur predominantly in those with spectrum symptoms, however more study is required. Some adjustments in the criteria for spectrum disorder (ie, loosening) may be required for that diagnosis to capture all affected persons. Considering Inhibitors,research,lifescience,medical spectrum disorders as a relevant diagnostic category adds 5% to the prevalence of the schizophrenia diagnosis. Perhaps up to 20% of the spectrum group is impaired enough to require treatment. These observations may serve to broaden our concepts of schizophrenia, its manifestations, and beneficial treatment opportunities. Brain

structure and function in schizophrenia Brain structure One of the first discoveries in schizophrenia using modern imaging technologies isothipendyl was structural, first with computerized axial tomography (CAT) scanning and later with magnetic resonance imaging (MRI). Johnstone and Crow58 then Weinberger59 described enlarged cerebral ventricles in persons with the illness. Over time, an overwhelming number of confirmations have accumulated.59,60 Ventricular size is a crude and nonspecific indication of cerebral dysfunction, and possibly only an epiphenomenon of this illness. However, this observation has served to redirect interest toward examining the brain for abnormal characteristics in persons with the illness.
