A disability is a physical or mental impairment that substantially limits one or more major life activities such as learning, working, walking, seeing, and hearing. Here are some examples:
- Attention Deficit Disorder
- Blindness and Low Vision
- Chronic Health Impairments
- Deafness and Hearing Loss
- Developmental Disabilities
- Learning Disabilities
- Mobility Impairments
- Psychological Impairments
- Acquired Brain Injury
ATTENTION DEFICIT DISORDER
Definition: Attention deficit disorder (ADD) is a neuro-biological disorder. Malfunctions in brain chemistry result in inattention, impulsiveness or hyperactivity. Symptoms appear in childhood, are chronic in nature and not attributable to other physical, mental, or emotional causes.
Educational Limitations: ADD results in limitations in completing tasks, controlling impulsivity, or sustaining attention, and concentration.
Definition: Blindness is often thought to be complete loss of vision with no remaining perception of light. However, this ultimate form of blindness is rare. Far more students have a permanent loss of some, but not all, of their eyesight. Blindness can be either congenital (occurring before or at birth), or a result of trauma, or a medical disorder. The severity of vision loss varies widely. The definition of legally blind is 20/200 vision with best correction. The most prevalent eye diseases are age-related macular degeneration, cataracts, diabetic retinopathy, retinitis pigmentosa, and glaucoma. Other vision impairments may be the result of night or color blindness, myopia (nearsightedness), astigmatism (irregular curvature of the cornea), hyperopia (farsightedness), and presbyopia where the eye lens becomes elastic.
Educational Limitations: Students who are blind or low vision will have limitations in reading, viewing classroom materials, boards, overheads, videos and other visual presentations. Getting around the campus will be a limitation and locating places or materials in labs and classrooms. In addition, visual perceptual problems such as discriminating figure or ground, sequencing, or reading similarly shaped letters or words may preclude comprehension of printed test materials. Students with low vision vary greatly in their ability to use vision. They may be limited in sharpness of vision or ability to see distances, or the student may have reduced central or peripheral vision. If the condition fluctuates, a student may have varying degrees of visual ability from day to day.
Definition: Deafness refers to a profound hearing loss of 90 decibels or greater. Hard of hearing refers to those students who have some residual hearing. Hearing loss may be conductive when there is a disruption of the transmission of sound through the outer and/or middle ear or sensorineural, which is due to sensory or nerve damage in the inner ear, auditory nerve, or auditory cortex of the brain. When the deafness is congenital (occurring before or at birth) or pre-lingual (before the age of about three when spoken language is normally acquired) the student will have significant communication impairments resulting from having a restricted exposure to language and social frame of reference when learning to speak, write, or lip-read.
Educational Limitations: The most significant limitation is that hearing loss cuts students off from the usual means of acquiring and transmitting spoken language. Deaf students cannot engage in spoken conversation, listen to information or enjoy the radio, television, movies, music, or video games. Limitations also include appreciating social nuance, jokes, and gossip exchanged by hearing people. Deafness limits hearing in various ways. Many deaf students are unable to perceive sounds, including speech, in a way for it to have meaning for ordinary purposes. Many other students have hearing impaired by background noise, cross talk and certain sound frequencies that limits accurate transmission of information. Deaf and hard of hearing students often are limited in mastering English grammatical structure despite intelligence and effort. Lip reading, while helpful, is only 30% to 40% effective and is very tiring.
CHRONIC HEALTH IMPAIRMENTS
Definition: Some chronic health impairments are visible disabilities, but many are invisible illnesses or medical conditions. In some cases the degree of impairment will vary from one day to the next because of the nature of the medical condition, the medication used, or the therapy required. When illnesses do not follow a set course, are progressive, or involve chronic pain, the student may additionally experience depression, anxiety, or other emotions. Chronic Health impairments include AIDS, allergies, back disorders, burns, cancer, diabetes, fibromyalgia, heart disease, hemophilia, lupus, multiple sclerosis, muscular dystrophy, renal-kidney disease, respiratory disorders, seizure disorders, sickle cell anemia, Tourette's syndrome. Side effects of medication may include fatigue, memory loss, shortened attention span, loss of concentration, or drowsiness.
Educational Limitations: Medical complications result in a variety of limitations for these students including regular class attendance. In addition, attendance at particular times of day may be a limitation due to treatments or hospitalizations. Side effects of medication may limit classroom responses or taking tests in a timed situation. Some medical conditions may limit mobility, speech, vision, or muscle control. Students may be limited in their use of standard furniture or be limited in ability to concentrate for extended class periods.
Definition: Title V of the California Education Code defines the developmentally delayed learner as a student who exhibits below average intellectual functioning and potential for measurable achievement in instructional and employment settings.
Educational Limitations: When instruction goes beyond rote learning the student may have limitations with critical thinking, inferential reading, analysis or synthesis, and abstract reasoning.
Definition: Title V of the California Education Code defines learning disabilities as a persistent condition of presumed neurological dysfunction which may exist with other disabling conditions. This dysfunction continues despite instruction in standard classroom situations. Students with learning disabilities exhibit average to above average intelligence ability, severe processing deficits, severe aptitude-achievement discrepancies, and measured achievement in an instructional or employment setting.
Educational Limitations: Learning disabilities may result in limitations in the rate, accuracy, or efficiency of reading, writing, or math. A student with a learning disability does not lack aptitude or ability but is inhibited from demonstrating his or her true intelligence in at least one area of achievement (reading, writing, or math) due to the severe processing deficit. Time management, project organization or initiation, sustained attention, and social skills may be limited. Taking in information, retaining it, or expressing knowledge and understanding to others may be a challenge. The student will have uneven abilities and persistent deficits in auditory, visual, or memory functions.
Definition: There are a wide range of neuro-muscular and orthopedic impairments that are congenital, the result of illness, or accident related. Mobility impairments range from slight difficulties with movement to paralysis. Such impairments may be caused by disorders such as arthritis or multiple sclerosis, or they can have congenital causes such as cerebral palsy or muscular dystrophy. They can also be the result of illness, accidents, strokes, or injury to the spinal cord. Some students have impairments in arm or hand movement that are the result of repetitive strain injury. These strain injuries can fluctuate in severity and are susceptible to aggravation from overuse.
Educational Limitations: Impairments can be painful and can limit mobility, strength, speed, endurance, or coordination. Mobility impairments cause difficulties with movement and fine-motor activity. In some conditions, limitations are constant; in others, flare-ups increase limitations intermittently. Some students have difficulty walking; others can stand but cannot walk. Fatigue may be a factor in limiting mobility; many students are able to walk but need to conserve energy by using a wheelchair occasionally. Limitations may include physical access to classrooms, offices, and rest rooms. Limitations may include use of standard height desks or tablet chairs. Some students are limited in their use of stairs. Sometimes upper extremity limitations, which involve the use of hands or arms, can impact the student's ability to reach and manipulate. Limitations may include fine motor tasks such as writing class notes, taking essays and tests, doing homework, completing tasks in science labs,
or using computers.
Definition: Psychological disabilities cover a wide range of conditions varying in symptoms and severity. In college the most commonly observed diagnoses are disorders of mood such as bipolar disorder and major depression. Other conditions are anxiety and panic disorders, obsessive-compulsive disorder, post traumatic stress disorder and schizophrenia. These disabilities are recognized to have a biological basis and many can be treated with appropriate psychotherapy and psychiatric medications.
Educational Limitations: Most students with these disabilities are limited with communication because they react to the increased stress of college by withdrawing. Psychological disabilities limit times of class choice because the student's functioning fluctuates throughout the day. Student's attendance may be limited because of relapses or hospitalizations. Student's ability to read may be impaired due to inability to concentrate. Students may have difficulties in social settings and have panic attacks under the pressure of giving a speech or taking a test.
Acquired Brain Injury (Traumatic Brain Injury)
Definition: Traumatic brain injuries result from either external events such as an injury to the head from an accident or war related injury, or internal events, such as a tumor or stroke.
Educational Limitations: Limitations vary depending upon the type, location, and severity of the injury. The student is usually limited in cognitive functioning in the area of memory, concentration, speed of response, spatial reasoning, conceptualization, problem-solving, organization, time management or communication through reading, writing, speaking, or listening.
