The following are health and medical definitions of terms that appear in the Sign Language article.
Acquired: Anything that is not present at birth but develops some time later. In medicine, the word "acquired" implies "new" or "added." An acquired condition is "new" in the sense that it is not genetic (inherited) and "added" in the sense that was not present at birth. See the entire definition of Acquired
American Sign Language: Abbreviated ASL. A complete, complex language that employs signs made with the hands and other movements, including facial expressions and postures of the body, used primarily by people in North America who are deaf.
Brain: That part of the central nervous system that is located within the cranium (skull). The brain functions as the primary receiver, organizer and distributor of information for the body. It has two (right and left) halves called "hemispheres."
Deafness:Deafness is defined by partial or complete hearing loss. Levels of hearing impairment vary from a mild but important loss of sensitivity to a total loss of hearing. Older adults suffer most often from hearing loss. Age-related hearing loss affects 30 to 35 percent of the population between the ages of 65 and 75 years, and 40 percent of the population over the age of 75. The most common cause of hearing loss in children is otitis media, a disorder that affects predominantly infants and young children. A substantial number of hearing impairments are caused by environmental factors such as noise, drugs, and toxins. Many sensorineural hearing losses result from a genetic predisposition.
Imagery: Both a mental process (as in imagining) and a wide variety of procedures used in therapy to encourage changes in attitudes, behavior, or physiological reactions. As a mental process, it is often defined as "any thought representing a sensory quality." It includes, as well as the visual, all the senses - aural, tactile, olfactory, proprioceptive, and kinesthetic. See the entire definition of Imagery
Sign language: A language that employs signs made with the hands and other movements, including facial expressions and postures of the body, used primarily by people who are deaf. There are many different sign languages as, for example, British and American sign languages. British sign language (BSL) is not easily intelligible to users of American sign language (ASL). Unlike ASL, BSL uses a two-handed alphabet. In developing countries, deaf people may use the sign language of educators and missionaries from elsewhere in the world. For example, some deaf individuals in Madagascar use Norwegian sign language. By contrast, deaf children in Nicaragua have created their own sign language. Study of the emerging Nicaruagan sign language (NSL) has revealed that children naturally possess learning abilities capable of giving language its fundamental structure. See also: American sign language.
Stage: As regards cancer, the extent of a cancer, especially whether the disease has spread from the original site to other parts of the body. See also: Staging.
Vertigo is a feeling of spinning movement, and at times accompanied by nausea and vomiting occur. Vertigo is most often associated with an inner ear problem. The treatment for vertigo can be lifestyle changes and medication if necessary.
Fragile X syndrome is the most common inherited form of mental retardation. It's caused by a mutation on the X chromosome. People with Fragile X syndrome suffer from physical, social, emotional, speech, language, sensory, intelligence, and learning impairments. There is no definitive treatment for Fragile X, though there are ways to minimize the symptoms.
Learning disabilities can cause an individual to have trouble learning and using skills such as reading, listening, writing, reading, speaking, reasoning, and performing mathematics. There is no cure for learning disabilities. Parents and teachers working together to properly diagnose learning disabilities can properly plan a course of education. For some, medication may be appropriate as complimentary treatment.
Balance is a state of body equilibrium or stability. We often take for granted how dependent we are on a healthy balance system. When the system breaks down, however, patients will describe symptoms such as dizziness, vertigo, lightheadedness, or motion sickness.
Landau-Kleffner syndrome (LKS, infantile acquired aphasia, acquired epileptic aphasia, or aphasia with convulsive disorder), a childhood disorder that occurs between the ages of 3 and 7, is characterized by the sudden loss of speech, epileptic seizures, depression, hyperactivity, and aggressiveness.
Hearing loss (deafness) may be present at birth or it may manifest later in life. Deafness may be genetic or due to damage from noise. Treatment of deafness depends upon its cause.
Pendred syndrome, a genetic disorder that causes hearing loss. Generally, the hearing loss is affected in early childhood. Pendred syndrome also affects other parts fo the body (for example, the thyroid gland). Treatment is generally cochlear ear implants.
Children with auditory processing disorders often do not recognize subtle differences between sounds in words, even though the sounds themselves are loud and clear. Symptoms of auditory processing disorder include low academic performance, behavior problems, language difficulty, difficulty reading, and trouble paying attention. Treatment may involve auditory trainers, environmental modifications, auditory memory enhancement, and auditory integration training.
Balance is defined as a state of equilibrium. It takes significant amount of
work for this to occur in the body. The brain uses inputs from many sources to
understand where the body is located in relationship to the world and to allow
it to function. Sensory information from the eyes, ears, and position receptors
in the rest of the body help keep the body upright and allow it to move in a
coordinated fashion.
Information comes to cerebellar lobes located in the base of the brain from
the vestibular system in the inner ear, vision from the eyes, and proprioception
(position) receptors located throughout the body that send signals through the
spinal cord. The cerebellum uses that information to maintain posture,
coordinate body motions like walking and also coordinate fine motor skills like
using a pen to write.
Vertigo, a feeling of spinning movement and sometimes accompanied by nausea
and vomiting, occurs when an...
