Cerebral palsy


Cerebral palsy (CP) is a group of permanent movement disorders that appear in early childhood. Signs and symptoms vary between people. Often, symptoms include poor coordination, stiff muscles, weak muscles, and tremors. There may be problems with sensation, vision, hearing, swallowing and speaking. Often babies with cerebral palsy do not roll over, sit, crawl, or walk as early as other children their age. Difficulty with the ability to think or reason and seizures each occurs in about one third of people with CP. While the symptoms may get more noticeable over the first few years of life, the underlying problems do not worsen over time.

Cerebral palsy is caused by abnormal development or damage to the parts of the brain that control movement, balance, and posture.〔 Most often the problems occur during pregnancy; however, they may also occur during childbirth, or shortly after birth. Often the cause is unknown. Risk factors include premature birth, being a twin, certain infections during pregnancy such as toxoplasmosis or rubella, exposure to methylmercury during pregnancy, a difficult delivery, and head trauma during the first few years of life, among others.〔 About 2% of cases are believed to be due to an inherited genetic cause. A number of sub-types are classified based on the specific problems present. For example, those with stiff muscles have spastic cerebral palsy, those with poor coordination have ataxic cerebral palsy, and those with writhing movements have athetoid cerebral palsy. Diagnosis is based on the child's development over time. Blood tests and medical imaging may be used to rule out other possible causes.〔

CP is partly preventable through immunization of the mother and efforts to prevent head injuries in children such as through improved safety. There is no cure for CP; however, supportive treatments, medications, and surgery may help many individuals. This may include physical therapy, occupational therapy, and speech therapy. Medications such as diazepam, baclofen, and botulinum toxin may help relax stiff muscles. Surgery may include lengthening muscles and cutting overly active nerves. Often external braces and other assistive technology are helpful. Some children have near normal adult lives with appropriate treatment. While alternative medicines are frequently used there is no evidence to support their use.〔

CP is the most common movement disorder in children. It occurs in about 2.1 per 1,000 live births. Cerebral palsy has been documented throughout history with the first known descriptions occurring in the work of Hippocrates in the 5th century BCE. Extensive study of the condition began in the 19th century by William John Little, after whom it was called "Little disease". William Osler first named it "cerebral palsy" from the German "zerebrale Kinderlähmung" (cerebral child-paralysis). A number of potential treatments are being examined, including stem cell therapy. However, more research is required to determine if it is effective and safe.〔
==Signs and symptoms==

Cerebral palsy is defined as "a group of permanent disorders of the development of movement and posture, causing activity limitation, that are attributed to non-progressive disturbances that occurred in the developing fetal or infant brain."〔; Corrected in 〕 While the central feature of CP is a disorder with movement, difficulties with thinking, learning, feeling, communication and behavior often occur along with cerebral palsy.〔 Of those with CP, 28% have epilepsy, 58% have difficulties with communication, at least 42% have problems with their vision, and 2356% have learning disabilities.〔
Cerebral palsy is characterized by abnormal muscle tone, reflexes, or motor development and coordination. There can be joint and bone deformities and contractures (permanently fixed, tight muscles and joints). The classical symptoms are spasticity, spasms, other involuntary movements (e.g., facial gestures), unsteady gait, problems with balance, and/or soft tissue findings consisting largely of decreased muscle mass. Scissor walking (where the knees come in and cross) and toe walking (which can contribute to a gait reminiscent of a marionette) are common among people with CP who are able to walk, but taken on the whole, CP symptomatology is very diverse. The effects of cerebral palsy fall on a continuum of motor dysfunction, which may range from slight clumsiness at the mild end of the spectrum to impairments so severe that they render coordinated movement virtually impossible at the other end of the spectrum.
Babies born with severe CP often have an irregular posture; their bodies may be either very floppy or very stiff. Birth defects, such as spinal curvature, a small jawbone, or a small head sometimes occur along with CP. Symptoms may appear or change as a child gets older. Some babies born with CP do not show obvious signs right away. Classically, CP becomes evident when the baby reaches the developmental stage at 6 to 9 months and is starting to mobilise, where preferential use of limbs, asymmetry, or gross motor developmental delay is seen.
Resulting conditions can include seizures, apraxia, dysarthria or other communication disorders, eating problems, sensory impairments, intellectual disability, learning disabilities, urinary incontinence, fecal incontinence, and/or behavioural disorders.
