Diseases caused by abnormal chromosomes or by defective genes inherited from one

or both parents.

Segments of DNA located on a chromosome that code for a specific hereditary trait

Occur when 1 gene out of 30,000 to 40,000 genes in the body has a harmful mutation.

When a gene carries incorrect instructions

Nerve cells use a brain chemical called dopamine to help control muscle movement. Parkinson's disease occurs when the nerve cells in the brain that make dopamine are slowly destroyed. Without dopamine, the nerve cells in that part of the brain cannot properly send messages. This leads to the loss of muscle function.

Degeneration of brain cells• Passed down through families• Causes:• uncontrolled bodily movements• facial grimaces• emotional disturbances• mental deterioration

Blood disease in which the body produces defective hemoglobin.

Blood disease inwhich the bodyproduces little or none of the

blood proteins necessary forclotting.

Disease of the body’s mucous glands. It primarily affects the respiratory and digestive systems of children and young adults.

More than one gene influences the onset of a disease. Lifestyle behaviors can contribute to a person’s chance of developing a complex disease

CVD’s such as stroke, high blood pressure, heart attacks, arteriosclerosis, type 2 diabetes and cancer are examples of complex diseases.

When a person inherits the wrong number of chromosomes or an incomplete chromosome.

Humans normally have 23 chromosomes in

each cell.

Most common chromosomaldisease in the U.S. is Down Syndrome.

If the immune system does not function properly it can result in an immune disorder. Examples of immune disorders are allergies, asthma and AIDS.

When the immune system attacks the cells of the body that the immune system normally protect.

Rheumatoid Arthritis is an autoimmune diseases are in which the immune system attacks the joints.

Multiple Sclerosis occurs when the immune system attacks the fatty insulation of nerves

in the brain and spinal cord.

A disorder in one or more of the basic psychological processes involved in

understanding or in using language

Manifests itself as an imperfect ability to listen, think, speak, write, spell, or do

mathematical calculations. Usually have normal IQ but can’t perform academically

within the normal IQ range.

Common characteristicshyperactive behavior, short attention spans, impulsiveness, poor self concepts, delay in play development

Effects on motor proficiencyhard time with visual-motor coordination, fine motor coordination, bilateral coordination, balance, and difficulties in perception (sight, sound, touch, muscle feeling, smell, and taste)

Significantly sub-average general intellectual functioning; a wide continuum exists

Characteristics: short attention span, being

slow to understand and follow directions, being lovable and wanting to please, exhibiting a delay in physical and motor skills

Motor skills: similar to learning disabilities; Poor body image, poor spatial relations, (with themselves, others, and equipment), clumsy and lack balance

Students with mental disabilities benefit from a highly structured and consistent environment, as well as immediate praise

Suggestions: Structured, consistent environment, teach by demonstrations and verbalization, be brief with directions, affirm/praise valid attempts (instantly)

A condition exhibiting characteristics which over a long period of time (adversely affects

the child’s education):

Examples: Tourette’s syndrome, Bipolar, PDD (autism, asperger’s), Oppositional Defiant disorder

Characteristics: inability to learn that cannot be explained by intellectual, sensory, or health factors

inability to build or maintain satisfactory interpersonal relationship with peer or teachers

inappropriate behaviors or feelings under normal circumstances

general mood of unhappiness or depression tendency to develop physical symptoms or fears

associated with personal/school problems

Definition: Includes partial sight and blindness. Visual impairment, including blindness, means an impairment in vision that, even with correction, adversely affects a child’s educational performance

Characteristics: self stimulation mannerisms (rocking, clicking fingers), stand too close because don’t know distances

Motor skills: slow to walk and develop gross motor skills created by limited movement and exploration, higher body mass index (low levels of fitness)

May be a permanent or fluctuating impairment or deafness. Impairment in

hearing, whether permanent or fluctuating, that adversely affects a child’s education

performance; Deafness is a hearing impairment that is so severe that the child is impaired in processing linguistic information

through hearing, with or without amplification

Characteristics: social domain is hardest, frustration when multiple conversations are going on, withdrawal from game experiences if not given special assistance

Motor skills: Poor balance, learn at normal rate but most have lower fitness scores

May result from congenital causes, disease, injury. A severe orthopedic impairment that adversely affects a

child’s educational performance includes impairments caused by congenital anomaly (missing a limb), disease

(arthritis), and other causes (cerebral palsy, amputations, etc)

Characteristics: Some are average to above IQ while others have mild to severe learning disabilities

Cerebral Palsy is the orthopedic impairment found most often in public schools. Can have “mild” (generalized clumsiness or slight limp) to “severe” (dominated by reflexes, unable to ambulate, unable to speak, almost no control of motor function); Most common form is call spasticity which is hypertension of the tendons and muscles (look and feel stiff); the degree of severity depends on the different body parts involved.
