Uncoordinated movement is an abnormality of muscle control or an inability to finely coordinate movements, resulting in a jerky, unsteady, to-and-fro motion of the trunk or the limbs.
|

Ataxia, a medical term originated from the Greek language meaning " without order, " refers to disturbances in the control of body posture, motor coordination, speech control, and eye movements. Several brain areas, including the cerebellum and the spinocerebellar tracts, substantia nigra, pons, and cerebral cortex control these functions.
|
|
Developmental coordination disorder is diagnosed when children do not develop normal motor coordination (coordination of movements involving the voluntary muscles). Developmental coordination disorder has been known by many other names, some of which are still used today.
|
|
Lack of coordination in the muscles. Ataxia, an extreme lack of coordination of the muscles, is a symptom of damage to the central nervous system.

Mental retardation is described as a condition that is diagnosed before age 18, and includes below-average general intellectual function, accompanied by impairment in the person?s ability to acquire the skills necessary for daily living.
|
|
|
(Also called sociocultural or cultural-familial retardation) Mild mental retardation attributed to environmental causes and generally involving some degree of psychosocial disadvantage. The majority of persons suffering from mental retardation fall into the category of familial retardation rather than that of clinical retardation, which usually has neurological or other organic causes.
|
|
|
Below-average intellectual abilities that are present before the age of 18 and interfere with developmental processes and with the ability to function normally in daily life (adaptive behavior). The term mental retardation is commonly used to refer to people with an intelligence quotient (IQ) below 70.
|
|
Mental retardation is a developmental disability that first appears in children under the age of 18. It is defined as an intellectual functioning level (as measured by standard tests for intelligence quotient) that is well below average and significant limitations in daily living skills (adaptive functioning).

Mental retardation (MR) is a developmental disability that first appears in children under the age of 18. It is defined as a level of intellectual functioning (as measured by standard intelligence tests ) that is well below average and results in significant limitations in the person ' s daily living skills (adaptive functioning).

Numbness and tingling are abnormal sensations that can occur anywhere in your body, but are often felt in your hands, feet, arms, or legs.
|
|
Numbness and tingling are decreased or abnormal sensations caused by altered sensory nerve function. The feeling of having a foot " fall asleep " is a familiar one.
|
|
A seizure is a sudden change in behavior due to an excessive electrical activity in the brain.
|
|
A seizure is a sudden change in behavior characterized by changes in sensory perception (sense of feeling) or motor activity (movement) due to an abnormal firing of nerve cells in the brain. Epilepsy is a condition characterized by recurrent seizures that may include repetitive muscle jerking called convulsions.

Epilepsy is a condition characterized by recurrent seizures that may include repetitive muscle jerking called convulsions.
|
|
A temporary series of uncontrollable muscle spasms brought on by unusual electrical activity in the brain. Also known as convulsion, clonic seizure, or tonic-clonic seizure.
|
|
Children with epilepsy may have seizures only once in a while, or every day. Though seizures can be scary for parents and caregivers, they aren’t painful and are usually brief.
|
|
|
First Aid: SeizuresA seizure results from a sudden rush of abnormal electrical signals in the brain. Symptoms may range from a minor daze to uncontrollable muscle spasms(convulsion).In some cases, the victim may even lose consciousness.

Tremors are a type of involuntary shaking movement.
|
|
Tremor is an unintentional (involuntary) rhythmical alternating movement that may affect the muscles of any part of the body. Tremor is caused by the rapid alternating contraction and relaxation of muscles and is a common symptom of diseases of the nervous system (neurologic disease).

Uncontrollable eye movements are involuntary, rapid, and repetitive movement of the eyes.
|
|
Rhythmic, oscillating motions of the eyes are called nystagmus. The to-and-fro motion is generally involuntary.
|
|
Nystagmus is a condition in which there is involuntary and rhythmic movement or oscillation of the eye. It is often caused by an underlying ocular or neurological disorder.

Total blindness is the inability to tell light from dark, or the total inability to see. Visual impairment or low vision is a severe reduction in vision that can ' t be corrected with standard glasses or contact lenses and reduces a person ' s ability to function at certain or all tasks.
|
|
|
What Is Low Vision?When you have low vision, you need more than glasses or contact lenses to see well enough to get around and do day-to-day tasks.
|
|
|
Treatment for Low VisionUsing vision aids can help you do the things you need and want to do. There are many kinds of vision aids.
