A patient with wide open aortic regurgitation and high left ventricle end-diastolic pressure may have no murmur or a soft diastolic murmur depending upon its chronicity and left ventricular function symptoms 8dp5dt order 6.5 mg nitroglycerin amex. Mitral Stenosis Mitral stenosis is found almost exclusively with rheumatic heart disease but is occasionally heard in patients with congenital or even severe calciic mitral heart disease treatment centers for depression buy discount nitroglycerin. More signiicant mitral stenosis causes pulmonary hypertension as demonstrated by an increased pulmonic closure sound and evidence of right ventricular volume and pressure overload. In pure mitral stenosis, the left ventricle is protected and therefore not enlarged. A rumble is heard virtually exclusively at the apex and often requires exercise or auscultation in the left lateral decubitus position to be recognized. A rub is generated by the epicardial and pericardial surfaces coming in contact during parts of the cardiac cycle. Before an investigator can eliminate the diagnosis of pericardial disease, he or she should listen with the patient in the supine, left lateral decubitus, and leaning forward positions. As the hand is pressing the abdomen, the murmur is auscultated to determine whether or not it is enhanced. As their hearts decompensate, the dynamic nature of their pulses and in fact the murmur itself may change. In the mitral or tricuspid positions, the S2 opening sound intervals can be used to judge the height of the atrial pressure. Depending on the size of the prostheses (smaller are louder), there will be a systolic or diastolic low murmur. Valves must be evaluated regularly to ensure that the closing and opening sounds remain crisp and clear. Evidence of excessive endothelial ingrowth into the mechanical prosthesis will result in diminished opening and closing sounds. Maneuvers Occasionally maneuvers are performed to enhance or differentiate murmurs. For instance, the best way to hear a murmur of aortic regurgitation is to have the patient lean forward, grip hands to increase outlow resistance, take a deep breath in, and then exhale. As the patient is holding his or her breath in expiration, one listens carefully for the aorta regurgitation. Inspiration (natural and not forced) may increase low to the right side and enhance a murmur of tricuspid or pulmonic regurgitation or stenosis. Exercise, such as sit-ups, is occasionally used to increase blood low to enhance murmurs, particularly in mitral stenosis. Squatting is, however, a complex maneuver that simultaneously diminishes preload because of venous obstruction and increases afterload because of squatting and is often complicated by an unusual position making auscultation diicult. Valsalva can be performed to enhance underilling of the left heart and murmur of the hypertrophic cardiomyopathy with dynamic outlow tract obstruction. Speciic guidelines have been addressed by the American Heart Association and should be followed. If the patient has diicult auscultation of the pressures because of low output or large arms, the arm can be raised above the head for a few seconds while the cuf is inlated. A 68-year-old man with a long-standing history of hypertension and stable coronary disease complains of sudden severe acute chest pain radiating to his back. Which one of the following is the typical auscultatory inding in mitral valve prolapse Jerky, with full expansion followed by sudden collapse (Corrigan or water-hammer pulse) 3. Validity of the hepatojugular relux and clinical test for congestive heart failure. Diagnosis of severe mitral regurgitation due to non-rheumatic chordal abnormalities. Relation of third and fourth heart sounds to blood velocity during left ventricular illing. Accompanying symptoms may include dyspnea, nausea, vomiting, diaphoresis, lightheadedness, and palpitations. Vulnerable plaques usually cause only a mild or moderate degree of stenosis, contain a soft atherogenic lipid core, and are covered by a thin cap that can easily rupture. Conversely, stable plaques tend to be larger, less lipid laden, and covered by a thick ibrous cap. Numerous factors contribute to plaque vulnerability, including inlammation and sheer stress. When a vulnerable plaque ruptures, the inner lipidladen core is exposed to the bloodstream and activates multiple pathways leading to the rapid formation of a superimposed platelet- and ibrin-rich thrombus. Frank cardiogenic shock can present with small volume pulses and a narrow pulse pressure in addition to classic signs of shock (cool extremities and end-organ hypoperfusion manifest as altered mental status and oliguria). We now know that Q waves do not necessarily relect the transmurality of an infarct. Notably, the absolute peak as well as the combination of time to peak and duration of elevation ("area under the curve") of cardiac-speciic markers corresponds to the extent of myocardial injury, subsequent myocardial dysfunction, and overall 1-year mortality. Cardiac troponin I and T are proteins that originate from the cardiomyocyte apparatus and therefore are highly speciic for cardiac injury when detected in the systemic circulation. Notably, troponin levels can be elevated in the setting of renal dysfunction; thus interpretation must take this factor into account.

Recent Liver Biopsy Percutaneous needle biopsy of the liver is a commonly used, safe procedure that can be performed at the bedside. It often provides tissue diagnosis without resorting to general anesthesia and laparotomy, and most agree that it can be performed as an outpatient procedure provided facilities are available for short-term observation and hospitalization if necessary. Of note, liver biopsy provides no information regarding the site or nature of the obstructing lesion. Although liver biopsy remains the gold standard for diagnosing cirrhosis, noninvasive tools are being widely adopted, particularly in patients for whom the diagnosis is not in question. A 62-year-old white male is referred for evaluation of a persistently elevated serum aminotransferase. His medical history is notable for long-standing but well-controlled hypertension and hypercholesterolemia. On examination, his blood pressure is 139/62 mm Hg, heart rate 78 beats per minute, and he weighs 238 lb with a body mass index of 32. A 29yearold man presents with evidence of ascites and abnormal liver function tests. He denies alcohol con sumption but smokes (approximately one pack per day for the past 10 years). Which of the following phenotypes would most likely lead to this clinical presentation A 39-year-old woman is found to have the following iron studies: serum iron 184 g/mL, total iron binding capacity 250 g/mL, and serum ferritin 285 ng/mL (normal 25­240 ng/mL). Her liver function tests are normal, and she is asymptomatic with a normal physical examination. A 42-year-old gardener presents with an 8-month history of bullous lesions on the dorsum of his hands, his forearms, and his neck. Elastography, spleen size, and platelet count identify portal hypertension in patients with compensated cirrhosis. American Gastroenterological Association Institute technical review on the role of elastography in chronic liver diseases. Non-invasive assessment of liver ibrosis: between prediction/prevention of outcomes and cost-efectiveness. Liver injury activates hepatic stellate cells, transforming them into myoibroblasts that secrete excessive extracellular matrix proteins, thus leading to progressive ibrosis. Chronic liver disease and cirrhosis result in about 35,000 deaths each year in the United States. Cirrhosis is the eleventh leading cause of death in the United States and is responsible for 1. Alcoholic liver disease, once considered to be the predominant cause of cirrhosis in the United States, remains a signiicant etiologic factor, especially given that its interaction with hepatitis C infection accelerates ibrosis and development of cirrhosis. Other individuals have a multitude of the most severe symptoms of end-stage liver disease and, as such, have a limited chance for survival. Patients with clinically advanced cirrhosis present with ascites, jaundice, hypoalbuminemia, coagulopathy, and encephalopathy. In addition, there is marked muscle wasting, renal dysfunction as manifested by hepatorenal syndrome, and pulmonary abnormalities characterized by hepatopulmonary syndrome, portopulmonary hypertension, and hepatic hydrothorax. Complications of Cirrhosis Ascites Ascites is deined as an accumulation of excessive luid within the peritoneal cavity. Ascites formation in patients with cirrhosis is the result of portal hypertension, which, through several mechanisms leads to salt and water retention. Diagnostic Evaluation of Ascites he key steps in the evaluation of ascites include acquiring a thorough history and physical, obtaining an ascitic luid evaluation, and obtaining special tests. Clinically, ascites is suggested by the presence of abdominal distension, bulging lanks, shifting dullness, and elicitation of a "puddle sign" in patients in the knee-elbow position. Ascites may be graded as follows: grade 1, mild, only visible on ultrasound; grade 2, detectable with lank bulging and shifting dullness; and grade 3, gross ascites with marked abdominal distension. On physical examination, the presence of vascular spiders and abdominal wall collaterals are useful in supporting the diagnosis of chronic liver disease as a cause of ascites. The serum-ascites albumin gradient is superior to the exudatetransudate concept in the differential diagnosis of ascites. Paracentesis is routine for new-onset ascites in patients on admission and in patients who have a clinical deterioration. A popular option for the tap site is the left lower quadrant of the abdomen, two ingerbreadths medial and cephalad to the anterior superior iliac spine. Chylous ascites, caused by obstruction of the thoracic duct or cisterna chyli, most often is as a result of malignancy. In addition, ascites triglyceride concentrations are greater than those observed in plasma. Appropriate radiologic studies must be performed in such patients to rule out surgical causes of peritonitis. Factors associated with worsening of ascites include excess luid or salt intake, malignancy, venous occlusion. Some patients with mild ascites respond to sodium restriction or diuretics taken once or twice per week. Other patients require aggressive diuretic therapy, careful monitoring of electrolytes, and occasional hospitalization to facilitate even more intensive diuresis. Both conditions represent serious infections that carry a 10% to 30% mortality rate. Pleural efusions may result from the passage of ascitic luid across channels in the diaphragm. Umbilical and inguinal hernias are common in patients with moderate and massive ascites.

Another rarer cause of overlow proteinuria is lysozymuria in the setting of acute myelogenous leukemia symptoms mercury poisoning order nitroglycerin cheap online. Light chains may not be detected by the dipstick 9 medications that cause fatigue cheap nitroglycerin 2.5 mg, but a discrepancy between the dipstick and the quantitative measurement of proteinuria is a telltale sign for the presence of paraproteins. Sulfosalicylic acid can be used to detect light chains in the setting of a negative dipstick test for proteinuria. Tubular proteinuria: he protein excretion in patients with tubular injury mainly relects failure of the proximal convoluted tubule to reabsorb iltered protein and some tubular secretion of protein. Transient proteinuria: Transient excretion of a small amount of albumin is common in certain acute set tings including fever, pneumonia, exercise, and con gestive heart failure. Proteinuria Proteinuria is often an incidentally noted laboratory inding and, at other times, the central inding of a critically ill patient. Normal protein excretion is <150 mg per day with <10 to 20 mg of albumin excretion a day. Classification of Proteinuria Proteinuria can be classiied as overt proteinuria or microalbuminuria, which is detected by radioimmunoassay, enzyme-linked immunosorbent assay, or nephelometry. Lowlevel proteinuria that is not detect able by the dipstick may be clinically very signiicant. Microalbuminuria is the excretion of between 30 and 300 mg of albumin per gram of creatinine. Orthostatic proteinuria: Young patients with asymptomatic proteinuria should be evaluated for this condition in which there is predominantly proteinuria with upright position and not on recumbency. Although this is deemed to be a benign condition based on lack of kidney pathology on biopsy and a benign course with long-term follow-up over decades, this condition may occasionally relect the initial stage of a more serious kidney lesion and hence should be followed closely. Nonnephrotic proteinuria: Proteinuria in the nonnephrotic range if not from overlow proteinuria can represent tubulointerstitial disease or glomerular disease. Patients with a ratio of <1 could have either a glomerular or tubulointerstitial source for their proteinuria. In general, for glomerular lesions, the degree of proteinuria relects the extent of kidney disease unless there is advanced chronic kidney disease. Differential Diagnosis he diferential diagnosis of proteinuria is summarized in Table 62. Overlow proteinuria: Bence-Jones proteinuria, multiple myeloma, amyloidosis, lymphoma, Waldenstrom, monoclonal gammopathy of uncertain signiicance. Orthostatic proteinuria can be idiopathic and benign or rarely an early manifestation of a primary kidney disease. Tubular proteinuria: hese can be transient in the set ting of acute tubular injury such as aminoglycoside or cisplatininduced tubular injury as well as acute ischemic injury. Infections such as Legionella pneumonia, leptospirosis, and ehrlichiosis can cause acute interstitial nephritis. Glomerular proteinuria and nephrotic syndrome: his can be subclassiied as either primary kidney disease, genetic, or secondary to a systemic disease. Familial nephrotic syndrome with a number of mutations identiied in podocyte proteins including nephrin, podocin, and alpha-actinin-4. Infections associated with membranous nephropathy include hepatitis B, hepatitis C, malaria, syphilis, and schistosomiasis. Immune complex glomerulonephritis with low complements including systemic lupus, subacute bacterial endocarditis, cryoglobulinemia, membranoproliferative glomerulonephritis, and visceral abscess. Systemic features of weight loss and constitutional symptoms may relect an underlying malignancy. A family history of kidney disease may be a clue to Alport syndrome, especially if there is an Xlinked inheritance pattern. Lymphadenopathy that is pathologic may be a clue for an underlying lymphoma with a paraneo plastic nephrotic syndrome. Central to the extent and pace of the evaluation are the quantiication of the proteinuria, the presence of a nephritic component, and the level of accompanying kidney function. A careful history of drug intake, both prescribed and over-the-counter medications, may be useful in the evaluation of proteinuria. Dysmorphic red blood cells and red cell casts are indicative of glomerular pathology. Both overlow proteinuria with Bence-Jones proteins and tubular proteinuria can be detected by the urine immune electrophoresis looking for monoclonal light chains. In amyloido sis, there will be large amounts of albumin and light chains that are monoclonal in most patients. Both solid tumors and lymphomas can present with nephrotic syndrome, especially in the elderly. An exhaustive evaluation for an underlying malignancy does not need to be undertaken for all cases of nephrotic syndrome. Kidney ultrasound will reveal congenital absence or hypoplasia of one kidney, which leads to focal sclerosis. Kidney ultrasound may reveal hydronephrosis, and a void ing cystoureterogram may reveal relux as the etiology for proteinuria, especially in children. Therapy of Specific Kidney Conditions herapeutic approaches are summarized in Table 62. Overlow proteinuria is fully evaluated, and treatment is of the underlying myeloma, leukemia, or lymphoma. Patients with tubulointerstitial disease should have treatment for the underlying disorder including withdrawal of ofending drugs. Multiple myeloma with myeloma kidney or cast nephropathy will need speciic therapy. Idiopathic nephrotic syndrome is treated with ste roids alone for minimal change disease and focal scle rosis and a combination of steroids and melphalan or cyclophosphamide for membranous nephropathy.

A diet that is rich in fruits and vegetables and thereby high in potassium is beneicial and may lower the risk of stroke medications 7 rights discount nitroglycerin on line. A Mediterranean diet supplemented with nuts may be considered in lowering the risk of stroke symptoms of diabetes buy nitroglycerin 2.5 mg amex. On the basis of national survey data from 1999 to 2000 and 2007 to 2008, the prevalence of hypertension in the United States remained stable at 29%. Despite the improvements, however, rates of control were lower among Hispanics compared with whites and among those age 18 to 39 years compared with older individuals. Individuals who are normotensive at age 55 years have a 90% lifetime risk for developing hypertension. In a metaanalysis of 16 trials involving 70,664 prehypertensive patients, prehypertensive patients randomized to active antihypertensive treatment had a consistent and statistically signiicant 22% reduction in the risk of stroke compared with those taking placebo (P <. Behavioral lifestyle changes are recommended by the Seventh Joint National Committee as part of a comprehensive treatment strategy for hypertension. Because 9% of patients stopped therapy as a result of side efects, the authors recommended further trials be conducted. Further hypothesisdriven trials are warranted, however, to test diferences in eicacy of individual agents in speciic subgroups of patients. However, there was no efect on either the primary composite outcome or overall mortality. Pharmacogenomics may contribute to improving individualized selection of antihypertensive medications for stroke prevention. In the absence of target-organ damage, the target should be <135/85 mm Hg; in the presence of target-organ damage, the target should be <130/80 mm Hg. Similarly, on the basis of observational data from 19 cohorts with 177,025 participants showing lower salt intake to be associated with a lower risk of stroke and other cardiovascular outcomes, population-wide reductions in salt intake may be advocated as a way to reduce stroke risk. Obesity and Body Fat Distribution Stroke, along with hypertension, heart disease, and diabetes mellitus, is associated with being overweight or obese. Increasing public awareness and government initiatives have placed this pub lic health issue in the forefront. According to the National Center for Health Statistics data from the Department of Health and Human Services, in 2009 and 2010, the prevalence of obesity was 35. Among the race/ethnic groups surveyed in the United States, age adjusted rates of obesity indicate the highest rates in non Hispanic blacks (49. Men presenting with a waist circumference of >102 cm (40 in) and women with a waist circumference >88 cm (35 in) are categorized as having abdominal obesity. Adiposity, however, correlated with risk of ischemic heart disease for both sexes. When fat distribution measured by dual-energy x-ray absorptiometry in relation to incidence of stroke was studied, there was a signiicant association in both men and women between stroke and abdominal fat mass. Mounting evidence shows a graded positive relationship between stroke and obesity independent of age, lifestyle, or other cardiovascular risk factors. When diabetes mellitus, hypertension, dyslipidemia, and other confounders were taken into account, there was no signiicant increase in the incidence of hemorrhagic stroke. Adjustments for covariates in all these studies signiicantly reduced these associations. Some 36,000 Swedish subjects followed for >13 years again showed a signiicant decrease in stroke incidence when more than three healthy lifestyle goals, including normal weight, were met. Diabetes Mellitus People with diabetes mellitus have both an increased susceptibility to atherosclerosis and an increased prevalence of atherogenic risk factors, notably hypertension and abnormal blood lipids. Moreover, the prevalence of prediabetes among Americans age >65 years tested in 2005 through 2008 was estimated to be 50%. Diabetes mellitus more than doubles the risk for stroke, and 20% of patients with diabetes mellitus will die of stroke. Duration of diabetes mellitus also increases the risk of nonhemorrhagic stroke (by 3% per year of diabetes duration). Ageadjusted fatal, nonfatal, and total stroke event rates per 10,000 person-years for normal fasting plasma glucose (80­ 109 mg/dL), impaired fasting glucose (110­125 mg/dL), and undiagnosed diabetes mellitus (126 mg/dL) were 2. Age-speciic incidence rates and rate ratios showed that diabetes mellitus increased ischemic stroke incidence for all ages but that the risk was most prominent before age 55 years in blacks and before age 65 years in whites. Eighteen of the 30 strokes were fatal in the conventional group, and all 6 were fatal in the intensive group. In the Euro Heart Survey on Diabetes and the Heart, 3488 patients were enrolled, 59% without and 41% with diabetes mellitus. Evidence-based medicine was deined as the combined use of renin-angiotensin-aldosterone system inhibitors, -adrenergic receptor blockers, antiplatelet agents, and statins. Although stroke rates were not changed, there was an 50% reduction in cerebrovascular revascularization procedures. Participants were then randomized to receive intensive (glycated hemoglobin goal, <6. From the available clinical trial results, there is no evidence that reduced glycemia decreases the short-term risk of macrovascular events, including stroke, in patients with type 2 diabetes mellitus. A glycated hemoglobin goal of <7% has been recommended by the American Diabetes Association to prevent long-term microangiopathic complications in patients with type 2 diabetes mellitus. Whether or not control to this level also reduces the long-term risk of stroke requires further study. In patients with recent-onset type 1 diabetes mellitus, intensive diabetes therapy aimed at achieving near-normal glycemia can be accomplished with good adherence but with more frequent episodes of severe hypoglycemia. Despite the lack of convincing support from any individual clinical trial for intensiied glycemic control to reduce stroke incidence in patients with diabetes mellitus, a recent metaanalysis provided some supportive evidence in a subgroup of patients with diabetes mellitus. From 649 identiied studies, the authors identiied nine relevant trials, which provided data for 59,197 patients and 2037 stroke events. However, at levels of <130 mm Hg, there was a 40% increase in serious adverse events with no beneit for other outcomes.

It is not unlikely that startle seizures in patients with widespread cortical lesions frequently involving underlying white matter medications mothers milk thomas hale purchase online nitroglycerin, especially the pyramidal tract symptoms your having a girl buy cheap nitroglycerin 6.5 mg online, could be triggered after an initial exaggerated startle reflex. The precipitating stimulus would induce such a reflex and thus a bilateral motor contraction predominating in the hemiplegic side, reflecting activation of an abnormally facilitated subcortical loop. In addition, proprioceptive reafferentation from the muscles first involved at seizure onset, directly projecting to hyperexcitable motor and premotor cortices through a transcortical reflex loop, would then trigger the motor seizure itself [4]. Differential Diagnosis the main differential diagnoses of startle-induced seizures are non-epileptic disorders such as exaggerated startle reflex and hyperekplexia. The startle reflex is a defense reaction induced by sudden stimulation and occurs in normal subjects, but the exaggerated startle reflex is usually myoclonic and seen in various diseases including Creutzfeldt­Jakob disease, subacute sclerosing panencephalitis, tumor and cerebral vascular disorder [34]. Clinical features of hyperekplexia manifest as exaggerated startle responses and severe generalized stiffness (hypertonia) that result in a fall. Management Startle-induced seizures are usually refractory, though seizures tend to remit with increasing age (usually in late teenage years). In small case series, carbamazepine, clobazam, valproic acid, levetiracetam and lamotrigine have been found to be effective against startle-induced seizures [35­39]. In cases with massive hemiplegia, a focal resection of the cortex involved in the epileptogenic zone may be indicated. In a number of cases, the epileptogenic zone size can be far less extensive than the lesion. Some patients may have seizure control by other procedures of surgical treatment such as callosotomy and multiple subpial transection [40,41]. The somatosensory onset within the postcentral gyrus can be confirmed by intracranial recordings [5,45]. Movement-induced seizures appear to be triggered by activation of the joint position receptors of one joint or of a group of neighboring joints, and typically start with sensory symptoms close to the joint or group of joints involved, followed by tonic and often then clonic manifestations of one limb with or without involvement of axial muscles and spread bilaterally. Somatosensory signs usually precede motor signs, but rarely motor signs can inaugurate the seizure, are first focal, and secondarily spread [46,47]. The seizures are brief, without alteration of contact nor secondary generalization. Initial myoclonic jerks [48] and even atonic seizures in patients with widespread bilateral cerebral lesions [49] have been reported. Preparation for movement and the slow initiation of an action may reduce or abort the seizure. The seizures induced by movements should be distinguished from non-epileptic paroxysmal movement disorders, such as familial paroxysmal dystonic choreoathetosis and paroxysmal kinesigenic choreoathetosis. Familial paroxysmal dystonic choreoathetosis is linked to chromosome 2q35 with onset in childhood [50]. It is characterized by involuntary chorea, dystonia and ballism that typically last from half an hour to several hours. Paroxysmal kinesigenic choreoathetosis is characterized by involuntary dystonia and choreoathetosis induced by sudden voluntary movement, and has a duration which is usually less than 1 minute. The triggering of sensorimotor seizures by movement of one or several joints may be related to a hyperexcitable lesion localized in the rolandic cortex with afferent impulses arising from proprioceptive sensory stimulation of the involved muscles and joints [5]. Seizures Induced by Cutaneous Stimulation the individual trigger zone in seizures induced by cutaneous stimulation remains unchanged in each patient throughout their seizure history. Sensory disturbance such as numbness or tingling sensation may occur intermittently in the trigger zone and be accentuated before the seizure. The seizures induced by cutaneous stimulation start with localized paresthesia such as tingling sensations and then spread in the form of a Bravais­Jacksonian march preceding the tonic (more rarely clonic) motor signs which are initially focal and sometimes rapidly become bilateral. The localization of ictal somatosensory or somatomotor signs is closely related to the triggering spatially restricted cutaneous region. Goldie and Green [42] reported a case in which the seizure was evoked by the sole mental representation of the triggering stimulus. The seizure induced by tooth brushing was also reported in which the gums were the trigger zone [43,44]. Some patients can learn how to evoke seizures and self-induce seizures in order to perform important activities during the refractory period. To facilitate seizures triggered by cutaneous stimulation, patients may simultaneously carry out a movement of a joint (see below) close to the the cutaneous trigger zone. Proven startle-provoked epileptic seizures in childhood: semiologic and electrophysiologic variability. The primary-specific variety is the only reflex syndrome accepted by the Commission on Classification and Terminology of the International League Against Epilepsy as an age-related idiopathic localisation-related epilepsy syndrome (1989). Since a first meta-analysis of 111 published cases in 1992, more than 70 additional cases have been reported with three larger case series from the Bethel Centre [2,3], Mayo Clinic [4] and London [5] in addition to several single case reports. In reflex epilepsies, it remains a challenge to identify the tipping point, when normal physiological activities or sensations lead to recurrent extreme events [7]. Epilepsy in the Disease Clinical Features the age of onset is adolescence and in young adulthood, long after reading skills have been acquired. In other cases, seizures start with visual symptoms consisting of elementary visual hallucinations. Seizures characteristically progress to generalised seizure activity, if patients continue to read. Increasing the complexity of the epileptogenic stimuli seems to facilitate such recruitment. Task difficulty, complexity, emotional content, or duration enhance the chances of electrographic or clinical activation in reading epilepsy, suggesting that maximal neuronal interaction is at least a facilitating factor [6]. This recruitment can involve the participation and interaction of several cortical and subcortical structures activated by reading or the emotional content of the reading material (mesiotemporal/amygdala/limbic structures). It may rely on both existing and re-organised functional links between brain regions and need not be confined to physically contiguous brain sites or established neuronal links.
