  • Score gains in the Writing component of the Test have been the main focus of much of this research. Green (2004) presents the findings of four studies, all of which involved candidates whose average initial score was 5.0 and who were undertaking periods of English language instruction of not more than three months. Average score gains in these four studies were less than half a band. In these studies, the candidates who achieved a score of 5.0 or below on the first test tended to improve on the second, while those achieving a score of 7.0 tended to receive a...

  • Conduction Aphasia Speech output is fluent but paraphasic, comprehension of spoken language is intact, and repetition is severely impaired. Naming and writing are also impaired. Reading aloud is impaired, but reading comprehension is preserved. The lesion sites spare Broca's and Wernicke's areas but may induce a functional disconnection between the two so that lexical representations formed in Wernicke's area and adjacent regions cannot be conveyed to Broca's area for assembly into corresponding articulatory patterns.

  • Language in PPA The language impairment in PPA varies from patient to patient. Some patients cannot find the right words to express thoughts; others cannot understand the meaning of heard or seen words; still others cannot name objects in the environment. The language impairment can be fluent (that is, with normal articulation, flow, and number of words per utterance) or nonfluent. The single most common sign of primary progressive aphasia is anomia, manifested by an inability to come up with the right word during conversation and/or an inability to name objects shown by the examiner.

  • Language allows the communication and elaboration of thoughts and experiences by linking them to arbitrary symbols known as words. The neural substrate of language is composed of a distributed network centered in the perisylvian region of the left hemisphere. The posterior pole of this network is located at the temporoparietal junction and includes a region known as Wernicke's area. An essential function of Wernicke's area is to transform sensory inputs into their lexical representations so that these can establish the distributed associations that give the word its meaning. ...

  • Pure Alexia Without Agraphia This is the visual equivalent of pure word deafness. The lesions (usually a combination of damage to the left occipital cortex and to a posterior sector of the corpus callosum—the splenium) interrupt the flow of visual input into the language network. There is usually a right hemianopia, but the core language network remains unaffected. The patient can understand and produce spoken language, name objects in the left visual hemifield, repeat, and write.

  • The correspondence between individual deficits of language function and lesion location does not display a rigid one-to-one relationship and should be conceptualized within the context of the distributed network model. Nonetheless, the classification of aphasias of acute onset into specific clinical syndromes helps to determine the most likely anatomic distribution of the underlying neurologic disease and has implications for etiology and prognosis (Table 27-1). The syndromes listed in Table 27-1 are most applicable to aphasias caused by cerebrovascular accidents (CVA).

  • Gestures and pantomime do not improve communication. The patient does not seem to realize that his or her language is incomprehensible and may appear angry and impatient when the examiner fails to decipher the meaning of a severely paraphasic statement. In some patients this type of aphasia can be associated with severe agitation and paranoid behaviors. One area of comprehension that may be preserved is the ability to follow commands aimed at axial musculature.

  • The present book, Differential Diagnosis in Internal Medicine, first appeared as a German edition in 1952 and since then has been translated into 10 other languages. Over the past 50 years 19 German editions have been published, and now the 19th edition of the work, which has become the classic differential diagnosis textbook, is available in English for the first time. This book encompasses differential diagnosis across the spectrum of internal medicine, covering dermatology, neurology, and rheumatology, and provides the very latest knowledge including pathophysiological aspects.

  • Increasing numbers of children are recognised as experiencing an autistic spectrum disorder, and educational provision for most of these children is found within a mainstream school. Autistic spectrum disorders (ASDs) are also sometimes referred to as pervasive development disorders because they pervade so many areas of life and are intrinsic to that individual’s development.

  • Hemiparesis Hemiparesis results from an upper motor neuron lesion above the midcervical spinal cord; most such lesions are above the foramen magnum. The presence of other neurologic deficits helps to localize the lesion. Thus, language disorders, cortical sensory disturbances, cognitive abnormalities, disorders of visual-spatial integration, apraxia, or seizures point to a cortical lesion. Homonymous visual field defects reflect either a cortical or a subcortical hemispheric lesion.

  • lasso estimates can be obtained at the same computational cost as that of an ordinary least squares estimation Hastie et al. (òýýÀ). Further, the lasso estimator remains numerically feasible for dimensions m that are much higher than the sample size n. Zou and Hastie (òýý ) introduced a hybrid PLS regression with the so called elastic net penalty dened as "Ppj =Ô(ò ( j + Ô −)SjS). Here the penalty function is a linear combination of the ridge regression penalty function and lasso penalty function. A dišerent type of PLS, called garotte is due to Breiman (ÔÀÀç).
