creutzfeldt-jakob disease, central nervous system, transmissible spongiform encephalopathy, mad cow, new variant cjd, creutzfeldt-jakob disease, disorder involving rapid decrease of mental function, movement, abnormalities believed to be, damage done, brain by a protein, a prion, protein folds abnormally, seems to encourage other proteins to, become similarly misshapen, affecting ability to function, creutzfeldt-jakob disease, occur sporadically, no known reason, a result of exposure to contaminated products, genetically inherited, disorder is rare, occurring in, 1 out of 1 million people, first appears in midlife, beginning between ages 20, average age at onset of symptoms, in the late 50s, cases have occurred in adolescents, received growth hormone derived, pituitary glands of cadavers, dead bodies, prions cannot be destroyed by ordinary disinfection techniques used, prevent transmission of viruses, bacteria, hormone remains contaminated, exposure is believed to be responsible, the early onset, the disease in these people, cadaver-derived growth hormone has been replaced by synthetically manufactured growth hormone, this source of contagion is no longer a problem, cases have occurred, people were given corneal transplants from infected donors, from contaminated electrodes that were used in brain surgery, it was known how to properly disinfect instruments, a type of disease, new variant creutzfeldt-jakob disease has emerged, was first reported, in the u, k, in people who had eaten meat from cows who were fed infected bone meal, version, the disease found in cows has come to be known, "mad cow disease", nvcjd has been, "the human form of mad cow disease" in news accounts, disease tends to affect younger people, has early psychiatric manifestations, any cases of nvcjd reported, once symptoms appear, disorder progresses rapidly, confused, dementia, alzheimer's disease, forms of cjd, distinguished by extremely rapid progression from onset of symptoms to disability, death, a familial tendency to acquire the disorder, early symptoms include personality changes, coordination, creutzfeldt-jakob disease related to several other diseases also thought to be, prions, kuru, seen in new guinea women who ate the brains of deceased relatives, funerary ritual, scrapie, found in sheep, bovine spongiform encephalitis, "mad cow disease", rare human diseases, gerstmann-straussler-scheinker disease, fatal familial insomnia, personality changes, hallucinations, muscle twitching, muscle stiffness, nervous, jumpy feelings, changes in gait, walking, locomotion, lack of coordination, stumbling, falls, speech impairment, poor enunciation, hard-to-understand speech, mumbling, sleepiness, delirium, dementia develops rapidly, deterioration in all aspects of brain function, profound confusion, disorientation, additional symptoms that associated, memory loss, anxiety, stress, tension, rapid onset, progression, of symptoms is what distinguishes cjd from most other dementias, disorder involves rapidly progressive dementia, myoclonus, brief muscle contraction, "jerk", rigidity, a neurological, motor system examination shows muscle twitching, spasm, strong startle response, muscle tone increased, weakness, muscle wasting, loss of muscle tissue, abnormal reflexes, an increase, in the response of normal reflexes, examination of visual fields show areas of blindness that the person, not realize, loss of coordination related to visual-spatial perception changes, in the cerebellum, the brain that controls coordination, cerebellar ataxia, an eeg, electroencephalograph, a reading of electrical activity, the brain, characteristic changes indicating creutzfeldt-jakob disease, symptoms have been present, at least 3 months, though not diagnostic, presence, the 14-3-3 protein, in the spinal fluid, obtained by lumbar puncture, "spinal tap", highly suggestive, accompanied by other characteristic symptoms, ultimately, confirmed by brain biopsy, by a post-mortem examination, shows the characteristic spongiform, sponge-like, in the brain, no known cure, creutzfeldt-jakob disease, custodial care required early, in the course, medications needed to control aggressive behaviors, sedatives, antipsychotics, provide a safe environment, control aggressive, agitated behavior, meet physiologic needs, require monitoring, assistance, in the home, in an institutionalized setting, family counseling, help in coping, the changes required, home care, visiting nurses, aides, volunteer services, homemakers, adult protective services, community resources helpful in caring, creutzfeldt-jakob disease, behavior modification helpful, controlling unacceptable, dangerous behaviors, consists of rewarding appropriate, positive behaviors, ignoring inappropriate behaviors, the bounds of safety, reality orientation, repeated reinforcement of environmental, cues, help reduce disorientation, legal advice appropriate early, in the course, the disorder, to form advance directives, power of attorney, legal actions, make it easier to make ethical decisions regarding the care of an individual, creutzfeldt-jakob disease, outcome, very poor, complete dementia commonly occurs, 6 months, the onset of symptoms, the person becoming totally incapable of self-care, disorder is fatal, short time, 7 months, a few people survive, 2 years after diagnosis, the disorder, death, infection, heart failure, respiratory failure, infection, heart failure, respiratory failure, loss of ability to function, care, oneself, loss of ability to interact, side effects of medications, treat the disorder, the specific medication, death, creutzfeldt-jakob disease is not a medical emergency, early diagnosis, make the symptoms easier to control, allow patients time to make advance directives, give families additional time to come to terms, risk of transfer, the organism on equipment, tissue is minimized by the health care provider, treatment equipment is sterilized to kill organisms, medical histories of potential cornea donors that indicate a history of diagnosed, creutzfeldt-jakob disease rule out the use of those corneas, transplantation, most countries now have strict guidelines, infected cows, strict restrictions regarding what they, fed, to avoid the potential, transmission of cjd to humans.
