Conduction Aphasia
Conduction aphasia, also called associative aphasia, is an uncommon form of difficulty in speaking (aphasia). It is caused by damage to the parietal lobe of the brain. An acquired language disorder, it is characterised by intact auditory comprehension, coherent (yet paraphasic) speech production, but poor speech repetition. Affected people are fully capable of understanding what they are hearing, but fail to encode phonological information for production. This deficit is load-sensitive as the person shows significant difficulty repeating phrases, particularly as the phrases increase in length and complexity and as they stumble over words they are attempting to pronounce.Conduction Aphasia. (n.d.). Retrieved from http://www.asha.org/Glossary/Conduction-Aphasia/ People have frequent errors during spontaneous speech, such as substituting or transposing sounds. They are also aware of their errors and will show significant difficulty correcting them. For example: In 1970, Tim Sha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neurology
Neurology (from el, νεῦρον (neûron), "string, nerve" and the suffix -logia, "study of") is the branch of medicine dealing with the diagnosis and treatment of all categories of conditions and disease involving the brain, the spinal cord and the peripheral nerves. Neurological practice relies heavily on the field of neuroscience, the scientific study of the nervous system. A neurologist is a physician specializing in neurology and trained to investigate, diagnose and treat neurological disorders. Neurologists treat a myriad of neurologic conditions, including stroke, seizures, movement disorders such as Parkinson's disease, autoimmune neurologic disorders such as multiple sclerosis, headache disorders like migraine and dementias such as Alzheimer's disease. Neurologists may also be involved in clinical research, clinical trials, and basic or translational research. While neurology is a nonsurgical specialty, its corresponding surgical specialty is neurosurgery ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Encephalitis
Encephalitis is inflammation of the Human brain, brain. The severity can be variable with symptoms including reduction or alteration in consciousness, headache, fever, confusion, a stiff neck, and vomiting. Complications may include seizures, hallucinations, trouble speaking, memory problems, and problems with hearing. Causes of encephalitis include viruses such as herpes simplex virus and rabies virus as well as bacteria, fungi, or parasites. Other causes include autoimmune diseases and certain medications. In many cases the cause remains unknown. Risk factors include a immunosuppression, weak immune system. Diagnosis is typically based on symptoms and supported by blood tests, medical imaging, and analysis of cerebrospinal fluid. Certain types are preventable with vaccines. Treatment may include antiviral medications (such as acyclovir), anticonvulsants, and corticosteroids. Treatment generally takes place in hospital. Some people require artificial respiration.

Kurt Goldstein
Kurt Goldstein (November 6, 1878 – September 19, 1965) was a German neurologist and psychiatrist who created a holistic theory of the organism. Educated in medicine, Goldstein studied under Carl Wernicke and Ludwig Edinger where he focused on neurology and psychiatry. His clinical work helped inspire the establishment of The Institute for Research into the Consequences of Brain Injuries. Goldstein was forced to leave Germany when Hitler came to power because of his Jewish heritage. After being displaced, Goldstein wrote '' The Organism'' (1934). This focused on patients with psychological disorders, particularly cases of schizophrenia and war trauma, and the ability of their bodies to readjust to substantial losses in central control. His holistic approach to the human organism produced the principle of self actualization, defined as the driving force that maximizes and determines the path of an individual. Later, his principle influenced Abraham Maslow's hierarchy of needs. He ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sigmund Freud
Sigmund Freud ( , ; born Sigismund Schlomo Freud; 6 May 1856 – 23 September 1939) was an Austrian neurologist and the founder of psychoanalysis, a clinical method for evaluating and treating psychopathology, pathologies explained as originating in conflicts in the Psyche (psychology), psyche, through dialogue between a patient and a psychoanalyst. Freud was born to Galician Jews, Galician Jewish parents in the Moravian town of Příbor, Freiberg, in the Austrian Empire. He qualified as a doctor of medicine in 1881 at the University of Vienna. Upon completing his habilitation in 1885, he was appointed a docent in neuropathology and became an affiliated professor in 1902. Freud lived and worked in Vienna, having set up his clinical practice there in 1886. In 1938, Freud left Austria to escape Nazi persecution. He died in exile in the United Kingdom in 1939. In founding psychoanalysis, Freud developed therapeutic techniques such as the use of free association (psychology), free a ...

Theodor Meynert
Theodor Hermann Meynert (15 June 1833 – 31 May 1892) was a German-Austrian psychiatrist, neuropathologist and anatomist born in Dresden. Meynert believed that disturbances in brain development could be a predisposition for psychiatric illness and that certain psychoses are reversible. In 1861 he earned his medical doctorate, and in 1875 became director of the psychiatric clinic associated with the University of Vienna. Some of his better known students in Vienna were Josef Breuer, Sigmund Freud, who in 1883 worked at Meynert's psychiatric clinic, and Julius Wagner-Jauregg, who introduced fever treatment for syphilis. Meynert later distanced himself from Freud because of the latter's involvement with practices such as hypnosis. Meynert also ridiculed Freud's idea of male hysteria; though some authors believe this to be due to his own hidden suffering of the illness, prompting a reconciliation with Freud near to his death. Other famous students of Meynert's were Russian neurops ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Receptive Aphasia
Wernicke's aphasia, also known as receptive aphasia, sensory aphasia or posterior aphasia, is a type of aphasia in which individuals have difficulty understanding written and spoken language. Patients with Wernicke's aphasia demonstrate fluent speech, which is characterized by typical speech rate, intact syntactic abilities and effortless speech output. Writing often reflects speech in that it tends to lack content or meaning. In most cases, motor deficits (i.e. hemiparesis) do not occur in individuals with Wernicke's aphasia. Therefore, they may produce a large amount of speech without much meaning. Individuals with Wernicke's aphasia are typically unaware of their errors in speech and do not realize their speech may lack meaning. They typically remain unaware of even their most profound language deficits. Like many acquired language disorders, Wernicke's aphasia can be experienced in many different ways and to many different degrees. Patients diagnosed with Wernicke's aphasia ...

Carl Wernicke
Carl (or Karl) Wernicke (; ; 15 May 1848 – 15 June 1905) was a German physician, anatomist, psychiatrist and neuropathologist. He is known for his influential research into the pathological effects of specific forms of encephalopathy and also the study of receptive aphasia, both of which are commonly associated with Wernicke's name and referred to as Wernicke encephalopathy and Wernicke's aphasia, respectively. His research, along with that of Paul Broca, led to groundbreaking realizations of the localization of brain function, specifically in speech. As such, Wernicke's area (a.k.a. Wernicke's Speech Area) has been named after the scientist. Biography Wernicke was born on May 15, 1848, in Tarnowitz, a small town in Upper Silesia, Prussia, now Tarnowskie Góry, Poland. He obtained his secondary education at the gymnasium in Oppeln, which is a school near the university of Breslau. Wernicke then studied medicine at the University of Breslau and did graduate work studying la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Expressive Aphasia
Expressive aphasia, also known as Broca's aphasia, is a type of aphasia characterized by partial loss of the ability to produce language ( spoken, manual, or written), although comprehension generally remains intact. A person with expressive aphasia will exhibit effortful speech. Speech generally includes important content words but leaves out function words that have more grammatical significance than physical meaning, such as prepositions and articles. This is known as "telegraphic speech". The person's intended message may still be understood, but their sentence will not be grammatically correct. In very severe forms of expressive aphasia, a person may only speak using single word utterances.ASHA.orgAppendix: Common Classifications of Aphasia. (n.d.).

Paul Broca
Pierre Paul Broca (, also , , ; 28 June 1824 – 9 July 1880) was a French physician, anatomist and anthropologist. He is best known for his research on Broca's area, a region of the frontal lobe that is named after him. Broca's area is involved with language. His work revealed that the brains of patients with aphasia contained lesions in a particular part of the cortex, in the left frontal region. This was the first anatomical proof of localization of brain function. Broca's work also contributed to the development of physical anthropology, advancing the science of anthropometry. Biography Paul Broca was born on 28 June 1824 in Sainte-Foy-la-Grande, Bordeaux, France, the son of Jean Pierre "Benjamin" Broca, a medical practitioner and former surgeon in Napoleon's service, and Annette Thomas, a well-educated daughter of a Calvinist, Reformed Protestant, preacher. Huguenot Broca received basic education in the school in his hometown, earning a bachelor's degree at the age of 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Aphasia Battery
Western Aphasia Battery (WAB) is an instrument for assessing the language function of adults with suspected neurological disorders as a result of a stroke, head injury, or dementia. There is an updated version, the Western Aphasia Battery-Revised (WAB-R). It helps discern the presence, degree, and type of aphasia. It also measures how the patient performed on the test to provide a baseline so they can detect changes throughout their time in therapy. This also allows to see the patient's language strengths and weaknesses so that they can figure out what to treat, and lastly, it can infer the location of the lesion that caused aphasia. Another such test is the Boston Diagnostic Aphasia Examination. The WAB targets English speaking adults and teens with a neurological disorder between the ages of 18 and 89 years old. The WAB tests both linguistic and non linguistic skills. The linguistic skills assessed include, speech, fluency, auditory comprehension, reading and writing. The non-ling ...
