1. Cerebral palsy
Cerebral palsy is a catch-all term for a collection of neonatal motor and neurologic disorders that is nonprogressive and nonhereditary. Intrauterine hypoxia and perinatal asphyxia is believed to be the major cause. Characteristic disorders: * spastic forms: quadriplegia, diplegia, hemiplegia, paraplegia, monoplegia, triplegia * ataxia * dyskinesia * hypotonia Many sufferers have a mixture of several motor problems and are associated with seizures, mental retardation, and sensory/speech deficits.

2. Cri-du-chat syndrome
Cri-du-chat syndrome is characterized by mental retardation, cat-like cry, abnormally small head, round face, hypertelorism, micrognathia and hypotonia. This syndrome is associated with deletion of the short arm of chromosome 5.

3. Down's syndrome (Down syndrome, Trisomy 21)
Physical characteristics of a person with Down's syndrome include small and short head, flat nasal bridge, reddish cheeks, dry lips, large, protruding tongue, small ears, epicanthal folds, and short neck. Mental retardation and hypotonia are also major symptoms, the degree of which varies with individuals. There is also a high incidence of congenital heart diseases and duodenal atresia . With good support, persons with this syndrome can develop their full potential. An Alzheimer -like dementia often occurs in the fourth and fifth decades and leads to a shortened life expectancy. The chromosomal abnormality is diagnostic. In 95% of cases, trisomy 21 is present (one extra chromosome 21), and in the rest which has the usual 46 chromosomes present, there is an abnormal translocation involving chromosome 21.

4. Hypertonia (hypertonicity)
More than usual tension in a body part, particularly the skeletal muscles or arteries. Hypertonia is the opposite of hypotonia .

5. Hypotonia
Less than usual tension in any body part, especially the arteries or the skeletal muscles. In the case of muscles, this can result in the ability to stretch the relaxed muscle much farther than normal. hypotonia is the opposite of hypertonia .

6. Olivopontocerebellar degeneration
An inherited disease esp. of mid to late life that is characterized by ataxia , hypotonia , dysarthria , and degeneration of the cerebellar cortex , middle cerebellar peduncle s, and inferior olive s.
