Friedreich's Ataxia
|
|
Friedreich's AtaxiaFriedreich's Ataxia is a slowly progressive disorder of the nervous system and muscles characterized by the inability to coordinate voluntary muscle movements (ataxia). This condition is caused by degeneration of nerve tissue in the spinal cord and of nerves that extend to peripheral areas such as the arms and legs. It affects upper and lower limbs, and the head and neck. There is also some loss of the sensations of touch and pressure in the arms and legs.
RELATED TERMS--------------------------------------
Ataxia
Ataxia is unsteady and clumsy motion of the limbs or trunk due to a failure of the fine coordination of muscle movements. The cerebellum is the center of the fine coordination of muscle movements, while the information emerging from it is carried to the muscles by the spinal cord and peripheral nerves, respectively. Therefore a disorder in either the spinal cord or in the peripheral nerves can cause ataxia.
Muscle
Tissue made up of bundles of long, slender cells that contract when stimulated.
Condition
The term "condition" has a number of biomedical meanings including the following: 1.An unhealthy state, such as in "this is a progressive condition." 2.A state of fitness, such as "getting into condition." 3.Something that is essential to the occurrence of something else; essentially a "precondition." 4.As a verb: to cause a change in something so that a response that was previously associated with a certain stimulus becomes associated with another stimulus; to condition a person, as in behavioral conditioning.
Nerve
Tissue that conveys sensation, temperature, position information to the brain.
Tissue
Biological tissue is a group of cells that perform a similar function.The study of tissues is known as histology, or, in connection with disease, histopathology.The classical tools for studying the tissues are the wax block, the tissue stain, and the optical microscope, though developments in electron microscopy, immunofluorescence, and frozen sections have all added to the sum of knowledge in the last couple of decades.
Cord
1. In anatomy, a long ropelike structure. 2. Short for the spinal cord or the umbilical cord.
Peripheral
At or near the surface of the body. Located away from the center structure.
Arms
An appendage in anatomy and in clinical trials. See: Arm.

Frottage
See frotteurism.
Frotteur
One who has the syndrome of frotteurism.
Frotteurism
A paraphilia of the solicitational/allurative type in which sexuoerotic arousal and facilitation or attainment of orgasm are responsive to and contingent on rubbing especially the genital area against the body of a stranger in a densely packed crowd. There is no technical name for the reciprocal paraphilic condition, namely being sexuoerotically dependent on being rubbed by a stranger. Synonym, frottage. See also toucheurism. the condition in which a person (a frotteur) is dependent on rubbing against and feeling the genital or other region of the body of a stranger, especially in a tightly packed crowd, in order to obtain erotic arousal and facilitate or achieve orgasm.
Fuck
The Anglo-Saxon synonym for sexual intercourse, coition, or copulation (all Latin-derived). To copulate and to fuck are the only one-word verbs for mutual genital intercourse. The former is too stilted for vernacular use. The latter, being tabooed as dirty, is often replaced by euphemisms like to screw or to ball.
Fugue
An altered state of consciousness in which what is happening now is unrelated to, or dissociated from what had happened then, in the preceding phase of existence; as for example in the alternating manifestations of dual or multiple personality. A state of dissociation, which subsequently may be followed by an amnesia for events which occurred during the state of dissociation.
Friedreich's Ataxia
False negative report
A negative result when in reality it is positive in nature.
False positive report
A positive result when in reality it is negative in nature.
Fats
One of the three main classes of food and a source of energy in the body. Bile dissolves fats, and enzymes break them down. This process moves fats into cells.
Fatty liver
The buildup of fat in liver cells. The most common cause is alcoholism. Other causes include obesity, diabetes, and pregnancy. Also called steatosis.
Fecal fat test
A test to measure the body's ability to break down and absorb fat. The patient eats a fat-free diet for 2 to 3 days before the test and collects stool samples for examination.
