1/320. Utility of a microcomputer as an external memory aid for a memory-impaired head injury patient during in-patient rehabilitation.memory deficit is one of the most frequent cognitive complications encountered after brain injury. It is recognized as difficult to treat. Over the past decades, various strategies of memory remediation have been used. Among them, prosthetic devices, such as notebooks and alarms, have shown some benefit. This study describes the case of a 22-year-old man who demonstrated deficits in memory and executive function. In an in-patient rehabilitation setting, a microcomputer was introduced as an external memory aid. With this intervention, the patient demonstrated an immediate improvement in the ability to attend every therapy and ask for every medication on his schedule. This case study demonstrates the usefulness of a microcomputer as an external memory aid for a memory-impaired head injury survivor.- - - - - - - - - - ranking = 1keywords = brain injury, injury, brain (Clic here for more details about this article) |
2/320. Selected legal issues in movement disorders.This article explores the long-standing question of whether trauma causes Parkinson's disease, and discusses the impact of informed consent and confidentiality in issues of genetic testing for Huntington's disease. Neurologists are appropriately concerned about the legal aspects of genetic testing, and this article attempts to address that subject from a medical-legal perspective.- - - - - - - - - - ranking = 0.0010664330924436keywords = trauma (Clic here for more details about this article) |
3/320. Right median nerve electrical stimulation to hasten awakening from coma.Electrical stimulation of the right median nerve may hasten the awakening of closed head injured, comatose patients. A series of 25 comatose patients have been treated. These patients made better recoveries than similar individuals reported in the literature. In a double-blind pilot project patients in the treated group scored better on interval glasgow coma scale scores, spent fewer days in the intensive care unit, and showed better Glasgow Outcome Scores at 1 month post-injury. Peripheral electrical stimulation of the right median nerve, through activation of the ascending reticular activating system, may be sufficient to arouse the moderate to severely comatose patient.- - - - - - - - - - ranking = 0.12947464800498keywords = injury (Clic here for more details about this article) |
4/320. Primary brainstem injury: benign course and improved survival.Primary brainstem injury following head injury is a rare event. The victims often have features of supratentorial injury, and a primary isolated injury to the brainstem occurring due to shearing stresses or to injury from the tentorial edge is extremely rare. In the presence of supratentorial injury, these patients may have altered sensorium. Isolated brainstem injury may manifest itself as internuclear ophthalmoplegia, anisocoria, rigidity and cerebellar tremor. Such injuries are now being diagnosed more often due to improved imaging techniques. We treated nine such cases who had sustained primary brainstem injury in road traffic accidents, all but one of whom were subsequently independent. Primary brainstem injuries need not be associated with poor prognosis and mortality and may run a benign course with good quality of survival.- - - - - - - - - - ranking = 1.6112356837902keywords = injury, brain (Clic here for more details about this article) |
5/320. wisconsin Card Sorting Test performance following head injury: dorsolateral fronto-striatal circuit activity predicts perseveration.The wisconsin Card Sorting Test (WCST) has been argued to be a sensitive indicator of frontal lobe function. However, several recent studies have failed to find a consistent relationship between structural damage to this cortical area and perseveration on the test. In the present study, positron emission tomography (PET) imaging with 18F-fluorodeoxyglucose was used to examine the relationship of regional brain metabolism to perseverative responding on the WCST in patients with a history of closed-head injury. An inverse relationship was found between perseverative responses and metabolism in the right, but not the left, dorsolateral prefrontal cortex and caudate nucleus. Perseverative responding was not related to metabolism in several other regions of the frontal lobes and basal ganglia, including the putamen and the frontal poles bilaterally. These data suggest that the functional integrity of the right dorsolateral frontal-subcortical circuit is critical for WCST performance.- - - - - - - - - - ranking = 0.65376656310607keywords = injury, brain (Clic here for more details about this article) |
6/320. Confabulation and delusional misidentification: a four year follow-up study.We describe a patient, AZ, who showed, in addition to an amnesic syndrome which eventually improved, longstanding confabulation and delusional misidentification following bilateral frontal and right temporal post-traumatic lesions. Confabulation appeared in personal recollections and on long-term verbal memory testing. Misidentification concerned mainly his wife and house. During the four year follow-up AZ's confabulation progressively shrinked so as to become restricted to verbal memory tasks. By contrast, misidentification persisted. General semantic memory was unimpaired throughout, while performance on frontal tests was initially poor and partly improved in time. We argue that confabulation and misidentification, though often intermingled and occurring after similar lesion pattern, should be considered as different neuropsychological entities.- - - - - - - - - - ranking = 0.0010664330924436keywords = trauma (Clic here for more details about this article) |
7/320. Isolated trigeminal neuropathy due to trigeminal nerve root hemorrhage.BACKGROUND: Isolated trigeminal neuropathy is uncommon; causes include trauma, inflammation, or neoplasm. methods: We report a patient who fell and struck his head during a myocardial infarction, was treated with streptokinase, and developed symptoms and signs of an isolated trigeminal sensory neuropathy. RESULTS: Imaging showed hemorrhage in the trigeminal nerve root; follow-up imaging showed resolution of the hemorrhage, but no underlying structural lesion. CONCLUSION: A combination of head trauma plus thrombolysis resulted in an isolated trigeminal neuropathy.- - - - - - - - - - ranking = 0.0021328661848873keywords = trauma (Clic here for more details about this article) |
8/320. aneurysm of the posterior inferior cerebellar artery caused by a traumatic perforating artery tear-out mechanism in a child.Traumatic posterior circulation aneurysms in the absence of fractures and penetrating wounds are extremely uncommon, especially in children. To our knowledge this is the first traumatic posterior inferior cerebellar artery(pica) aneurysm reported that cannot be related to a skull fracture or a trauma caused by the edge of a rigid meningeal structure. In the present case, the initial subarachnoid hemorrhage (SAH) was caused by a perforating artery, originating from the pica, which was torn out as the result of a deceleration trauma. Such a mechanism explains both the initial SAH and the development of the false aneurysm responsible for the second SAH.- - - - - - - - - - ranking = 0.0074650316471055keywords = trauma (Clic here for more details about this article) |
9/320. magnetic resonance imaging findings of Kernohan-Woltman notch in acute subdural hematoma.OBJECTIVE AND IMPORTANCE: We report the case of a 73-year-old patient who presented a right motor deficit caused by an ipsilateral acute subdural hematoma. A magnetic resonance imaging (MRI) demonstration of Kernohan-Woltman notch phenomenon was obtained. CLINICAL PRESENTATION: The woman sustained a major head injury at home, followed by loss of consciousness. On admission to the emergency room, she was comatose, anisochoric (left > right), and showed a reaction to pain with decerebrating movements of left limbs (glasgow coma scale (GCS) 4/15). A right severe hemiparesis was observed. Cerebral computed tomography scan showed a large right hemispheric subdural hematoma. INTERVENTION AND POST-OPERATIVE COURSE: A wide right craniotomy was performed and the subdural hematoma evacuated. During the post-operative period, the level of consciousness gradually improved. A MRI performed about 2 weeks after operation showed a small area of abnormal signal intensity in the left cerebral peduncle. On discharge, the woman was able to communicate with others, but her right hemiparesis was still severe.- - - - - - - - - - ranking = 0.12947464800498keywords = injury (Clic here for more details about this article) |
10/320. sports-specific concerns in the young athlete: football.There are over 1.5 million males playing American football at all levels in the united states. American football is the most common participant sport among high-school-aged males. Owing to its high rate of injury per exposure hour, American football injuries are commonly treated in the emergency department during the autumn sports season. This article will review the history, epidemiology, and specific injury patterns seen in American football, with a focus on head and shoulder injuries.- - - - - - - - - - ranking = 0.25894929600997keywords = injury (Clic here for more details about this article) |
