Neurofibromatosis Research Paper
Introduction
Neurofibromatosis is a genetic disorder of the nervous system. This disorder contains three different categories. Neurofibromatosis type 1 (NF1), neurofibromatosis type 2 (NF2), and Schwannomatosis. Each disorder has specific characteristics that set them apart. These disorders affect growth and nerve cell tissue because tumors grow on nerve tissue throughout the nervous system. Depending on what cells are involved will dictate which disorder is seen. Each disorder has a specific type of tumor associated with it. It is estimated the 100,000 Americans have a neurofibromatosis disorder and they occur in both sexes and in all races and ethnic groups (NINDS).
Disease Characteristics
Neurofibromatosis 1 is commonly known as von Recklinghaus

If the disease is very severe then evaluations may be more frequent. MRI can reveal tumors of the vestibular nerve as small as a few millimeters in diameter. Surgical options depend on tumor size and if hearing loss will be inflicted. Damaging the auditory nerve is easier as the tumor increases. However sometimes a cochlear implant or an auditory brain stem implant can be implemented to recover hearing. Cataracts or retinal abnormalities are corrected through surgery as well.
Disease Characteristics
Schwannomatosis is a rare form of neurofibromatosis that is just recently being recognized. It rarely affects people before their 20s or 30s making it different from NF1 and NF2. Schwannomatosis causes painful tumors called schwannomas and they develop on cranial, spinal, and peripheral nerves, but not the eighth cranial nerve. Schwannomatosis is the development of multiple schwannomas occurring everywhere in the body except on the vestibular nerve. Therefore, schwannomatosis does not cause hearing loss, it mainly causes chronic pain, occurring anywhere in the body. The pain is caused when the schwannomas enlarge, compresses nerves, or presses on adjacent

Essay On Cochlear Implants
941 Words | 4 PagesThe topic of cochlear implants is causing quite the argument between the deaf and medical community. The core of the disagreement centers around whether or not cochlear implantation should continue to be considered as an option for hearing impaired individuals to improve auditory ability.. According to the American Speech-Language-Hearing Association a cochlear implant is “a device that provides direct electrical stimulation to the auditory (hearing) nerve in the inner ear.” Proponents of cochlear implants claim that hose who are born with or later experience a problem with the sensory nerve of the inner ear have the opportunity to gain the ability to hearHowever, many are now arguing that this device is not as useful or healthy for the human ear as it has been said to be. Those who oppose cochlear implantation, namely the deaf community, view it as a threat to the deaf community and its culture.
Multiple Schlerosis Research Paper
875 Words | 4 PagesMultiple Sclerosis can come in many forms and can affect people very differently. It is a disease of the brain and spinal cord, it occurs from damage on the myelin sheath that is around the nerve fibers in the central nervous system. This affects the transmission of nerve signals between the brain, spinal cord, and the rest of the body. Early on symptoms of Multiple Sclerosis can include; stiffness, tingling, and blurred vision, the most common signs of a person with developed Multiple Sclerosis are muscle stiffness, joint problems, thinking problems, and some urinary problems. Currently there is no cure for the disease but there are many treatments to help with the disease.
Purdy's Argument
713 Words | 3 PagesHuntington’s Disease, “is an autosomal dominant disease, meaning it is caused by a single defective gene located on a non-sex chromosome” (Purdy 107). Huntington’s Disease is “passed from one generation to the next via affected individuals. Each child of such an affected person has a 50 percent risk of inheriting the gene and thus of eventually developing the disease” (Purdy 107). Huntington’s Disease is a lot more severe than someone being born deaf. Being deaf is a problem, but will not lead to your life being cut short like Huntington’s Disease.
Meniere's Disease Research Paper
824 Words | 4 PagesCutting the vestibular nerve permanently destroys inner ear balance, while preserving hearing, and is successful 95% of the time in controlling vertigo. Although, none of the surgical procedures to treat vertigo are useful in treating the hearing loss that often accompanies Meniere disease. Scientists estimate that 6 out of 10 people either get better on their own or can control their vertigo with diet, drugs or devices. However, a small group with Meinere 's Disease will get relief only by undergoing surgery.

Chronic Otitis Media Case Study
1588 Words | 7 PagesTable IV shows mean bone conduction hearing threshold at each frequency in the diseased ear in relation to the duration of pathology. It shows increased hearing loss with increasing duration of pathology and this relation was statistically significant (p > 0.05). There is 15dB or greater bone conduction hearing loss at one frequency or more in 42.8% of the patients involved in the study and there is 15dB or greater hearing loss at two frequencies or more in 21.4% of the patients. Table V shows mean bone conduction hearing thresholds at each frequency in relation to the type of pathology.
Physical Therapy Goals
1278 Words | 6 PagesThe patient’s goals included the ability to work a full shift and complete work duty activities, tolerate driving, and grocery shopping without any symptoms. Patient’s goals also included returning to family activities including ice-skating, riding roller coasters, and watching movies without any vestibular symptoms. Physical Therapy goals included the increasing vestibular function to improve quality of life and continuation of responsibilities without exacerbation of symptoms. Physical therapy focused on increasing patient’s static and dynamic balance, gaze stabilization, and activity tolerance to improve vestibular function. The patient’s prognosis was good due to her young age, no significant comorbidities, and level motivation to return to prior level of function without any vestibular symptoms.
Summary Of Opportunity By Edward Rowland Sill

Randel was born with a disease called neurofibromatosis. Neurofiromatosis is a genetic disorder that causes tumors to form on nerve tissue. These tumors can develop anywhere in your nervous system, which includes the brain, spinal cord and nerves.
Hearing Loss: A Genetic Disease
602 Words | 3 PagesHearing loss is not always a genetic disease. Causes of deafness can rapidly (ly) travel (v) from ear infections, trauma, loud noise, some medication, birth defects, heredity, and aging. In this paper I will be discussing a few of these types of these causes. [3] Unfortunately hearing loss affects young and old people and even dogs. [2] Concerning pets, I have learned that these diseases can affect pets too.
Cause Of Conductive Hearing Loss In Children
789 Words | 4 PagesThe hearing problem occurs when the sound transmission through the middle ear is blocked. Therefore, sound cannot be efficiently passed through the outer ear to the ear drum and to the middle ear.

The conductive hearing loss can happen to both ears and can be enduring or just a temporary problem.
