Cerebral refers to the affected area of the brain, the cerebrum (however the centers have not been perfectly localized and the disease most likely involves connections between the cortex and other parts of the brain such as the cerebellum) and palsy refers to disorder of movement. CP is caused by damage to the motor control centers of the young developing brain and can occur during pregnancy (about 75 percent), during childbirth (about 5 percent) or after birth (about 15 percent) up to about age three.. 
It is a non-progressive disorder, meaning the brain damage does not worsen, but secondary orthopedic difficulties are common. There is no known cure for CP. Medical intervention is limited to the treatment and prevention of complications possible from CP's consequences.
Onset of arthritis and osteoporosis can occur much sooner in adults with CP. Further research is needed on adults with CP, as the current literature body is highly focused on the pediatric patient. CP's resultant motor disorder(s) are sometimes, though not always, accompanied by "disturbances of sensation, cognition, communication, perception, and/or behavior, and/or by a seizure disorder".
CP is the second-most expensive developmental disability to manage over the course of a person's lifetime (second to mental disabilities), with an average lifetime cost per person of USD$921,000 (in 2003 dollars). The incidence in the six countries surveyed is approximately an average of 2.12–2.45 per 1000 live births; there has been a slight increase in recent years. Although improvements in neonatal nursing help reduce the number of babies who develop cerebral palsy, they also mean that babies with very low birth weights survive, and these babies are more likely to have cerebral palsy.
CP is divided into four major classifications to describe the different movement impairments. These classifications reflect the area of brain damaged. The four major classifications are:
In 30 percent of all cases of CP, the spastic form is found along with one of the other types. There are a number of other, less prevalent types of CP, but these are the most common.
A general classification is as follows:
Spastic (ICD-10 G80.0-G80.1) cerebral palsy is by far the most common type, occurring in 70% to 80% of all cases. People with this type are hypertonic and have a neuromuscular condition stemming from damage to the corticospinal tract, motor cortex, or pyramidal tract that affects the nervous system's ability to receive gamma amino butyric acid in the area(s) affected by the spasticity. Spastic CP is further classified by topography dependent on the region of the body affected; these include:
- spastic hemiplegia (one side being affected). Generally, injury to the left side of the brain will cause a right sided deficit, and vice versa.
- spastic diplegia ( the lower extremities are affected more than the upper extremities). Most people with spastic diplegia do eventually walk. The gait of a person with spastic diplegia is typically characterised by a crouched gait. Toe walking and flexed knees are common. Hip problems, dislocations, and side effects like strabismus (crossed eyes) are common. Strabismus affects three quarters of people with spastic diplegia. This is due to weakness of the muscles that control eye movement. In addition, these individuals are often nearsighted. In many cases the IQ of a person with spastic diplegia is unaffected by the condition.
- spastic quadriplegia (Whole body affected; all four limbs affected equally). Some children with quadriplegia also have hemiparetic tremors; an uncontrollable shaking that affects the limbs on one side of the body and impairs normal movement. A common problem for children with quadriplegia is fluid buildup. Diuretics and steroids are medications administered to decrease any buildup of fluid in the spine that is caused by leakage from dead cells. Hardened feces in a quadriplegia patient are important to monitor because it can cause high blood pressure. Autonomic dysreflexia can be caused by hardened feces, urinary infections, and other problems, resulting in the overreaction of the nervous system and can result in high blood pressure, heart attacks, and strokes. Blockage of tubes inserted into the body to drain or enter fluids also needs to be monitored to prevent autonomic dysreflexia in quadriplegia. The proper functioning of the digestive system needs to be monitored as well.
Ataxia (ICD-10 G80.4) type symptoms can be caused by damage to the cerebellum. Forms of ataxia are less common types of Cerebral Palsy, occurring in at most 10% of all cases. Some of these individuals have hypotonia and tremors. Motor skills like writing, typing, or using scissors might be difficult, as well as problems with balance, especially while walking. It is common for individuals to have difficulty with visual and/or auditory processing of objects.
Athetoid or dyskinetic (ICD-10 G80.3) is mixed muscle tone - sometimes hypertonia and sometimes hypotonia. People with athetoid CP have trouble holding themselves in an upright, steady position for sitting or walking, and often show involuntary motions. For some people with athetoid CP, it takes a lot of work and concentration to get their hand to a certain spot (like scratching their nose or reaching for a cup). Because of their mixed tone and trouble keeping a position, they may not be able to hold onto objects (such as a toothbrush or pencil). About one-fourth of all people with CP have athetoid CP. The damage occurs to the extrapyramidal motor system and/or pyramidal tract and to the basal ganglia. It occurs in 40% of all cases.
Incidence and prevalence
In the industrialised world, the incidence of cerebral palsy is about 2 per 1000 live births. The incidence is higher in males than in females; the Surveillance of Cerebral Palsy in Europe (SCPE) reports a M:F ratio of 1.33:1. Variances in reported rates of incidence across different geographical areas in industrialised countries are thought to be caused primarily by discrepancies in the criteria used for inclusion and exclusion. When such discrepancies are taken into account in comparing two or more registers of patients with cerebral palsy (for example, the extent to which children with mild cerebral palsy are included), the incidence rates converge toward the average rate of 2:1000.
Overall, advances in care of pregnant mothers and their babies has not resulted in a noticeable decrease in CP. This is generally attributed to medical advances in areas related to the care of premature babies (which results in a greater survival rate). Only the introduction of quality medical care to locations with less-than-adequate medical care has shown any decreases. The incidence of CP increases with premature or very low-weight babies regardless of the quality of care.[How to reference and link to summary or text]
The SCPE reported the following incidence of comorbidities in children with CP (the data are from 1980-1990 and included over 4,500 children over age 4 whose CP was acquired during the prenatal or neonatal period):
- Mental retardation (IQ < 50): 31%
- Active seizures: 21%
- Mental retardation (IQ < 50) and not walking: 20%
- Blindness: 11%
The SCPE noted that the incidence of comorbidities is difficult to measure accurately, particularly across centers. For example, the actual rate of mental retardation may be difficult to determine, as the physical and communicational limitations of people with CP would likely lower their scores on an IQ test if they were not given a correctly modified version.
Signs and symptoms
All types of CP are characterised by abnormal muscle tone, posture (i.e. slouching over while sitting), 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 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 virtually unnoticeable to"clumsy" and awkward movements on one end of the spectrum to such severe impairments that coordinated movements are almost impossible on 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, change, or become more severe as a child gets older. Some babies born with CP do not show obvious signs right away.
CP, then known as "Cerebral Paralysis", was first identified by English surgeon William Little in 1860. Little raised the possibility of asphyxia during birth as a chief cause of the disorder. It was not until 1897 that Sigmund Freud, then a neurologist, suggested that a difficult birth was not the cause but rather only a symptom of other effects on fetal development. Research conducted during the 1980s by the National Institute of Neurological Disorders and Stroke (NINDS) suggested that only a small number of cases of CP are caused by lack of oxygen during birth.
Despite years of debate, the exact cause of CP remains unclear.
Some contributing causes of CP are asphyxia, hypoxia of the brain, birth trauma, premature birth, and certain infections in the mother during and before birth such as strep infections, central nervous system infections, trauma, consecutive hematomas, placenta abruptio and multiple birth.
Between 40% and 50% of all children who develop cerebral palsy were born prematurely. Premature infants are at higher risk in part because their organs are not yet fully developed, increasing the risk of asphyxia and other injury to the brain, which in turn increases the incidence of CP. Periventricular leukomalacia is an important cause of CP. About 10% of cases with CP are caused by malformation of the CNS.
Recent research has demonstrated that intrapartum asphyxia is not the most important cause, probably accounting for no more than 10 percent of all cases; rather, infections in the mother, even infections that are not easily detected, may triple the risk of the child developing the disorder, mainly as the result of the toxicity to the fetal brain of cytokines that are produced as part of the inflammatory response. Low birthweight is a risk factor for CP--and premature infants usually have low birth weights, less than 2.0kg, but full-term infants can also have low birth weights. Multiple-birth infants are also more likely than single-birth infants to be born early or with a low birth weight.
After birth, other causes include toxins, severe jaundice, lead poisoning, physical brain injury, shaken baby syndrome, incidents involving hypoxia to the brain (such as near drowning), and encephalitis or meningitis. The three most common causes of asphyxia in the young child are: choking on foreign objects such as toys and pieces of food; poisoning; and near drowning.
Some structural brain anomalies such as lissencephaly cause symptoms of CP, although whether that could be considered CP is a matter of opinion (some people say CP must be due to brain damage, whereas these people never had a normal brain). Often this goes along with rare chromosome disorders and CP is not genetic or hereditary.
In order for bones to attain their normal shape and size, they require the stresses from normal musculature. Osseous findings will therefore mirror the specific muscular deficits in a given person with CP. The shafts of the bones are often thin (gracile). When compared to these thin shafts (diaphyses) the metaphyses often appear quite enlarged (ballooning). With lack of use, articular cartilage may atrophy, leading to narrowed joint spaces. Depending on the degree of spasticity, a person with CP may exhibit a variety of angular joint deformities. Because vertebral bodies need vertical gravitational loading forces to develop properly, spasticity and an abnormal gait can hinder proper and/or full bone and skeletal development. People with CP tend to be shorter in height than the average person because their bones are not allowed to grow to their full potential. Sometimes bones grow at different lengths, so the person may have one leg longer than the other.
CP is not a progressive disorder (meaning the actual brain damage does not worsen), but the symptoms can become worse over time due to 'wear and tear.' A person with the disorder may improve somewhat during childhood if he or she receives extensive care from specialists, but once bones and musculature become more established, orthopedic surgery may be required for fundamental improvement. People who have CP tend to develop arthritis at a younger age than normal because of the pressure placed on joints by excessively toned and stiff muscles.
The full intellectual potential of a child born with CP will often not be known until the child starts school. People with CP are more likely to have some type of learning disability, but this is unrelated to a person's intellect or IQ level. Intellectual level among people with CP varies from genius to mentally retarded, as it does in the general population, and experts have stated that it is important to not underestimate CP sufferer's capabilities and to give them every opportunity to learn.[How to reference and link to summary or text]
The ability to live independently with CP also varies widely depending on the severity of the disability. Some individuals with CP will require personal assistant services for all activities of daily living. Others can live semi-independently, needing support only for certain activities. Still others can live in complete independence. The need for personal assistance often changes with increasing age and the associated functional decline. However, in most cases persons with CP can expect to have a normal life expectancy; survival has been shown to be associated with the ability to ambulate, roll and self-feed.[How to reference and link to summary or text] As the condition does not directly affect reproductive function, some persons with CP have children and parent successfully.
According to OMIM, only 2% of cases of CP are inherited (with glutamate decarboxylate-1 as one known enzyme involved.) There is no evidence of an increased chance of a person with CP having a child with CP.
Treatment for cerebral palsy is a lifelong multi-dimensional process focused on the maintenance of associated conditions. In order to be diagnosed with cerebral palsy the damage that occurred to the brain must be non-progressive and not disease-like in nature. The manifestation of that damage will change as the brain and body develop, but the actual damage to the brain will not increase. Treatment in the life of cerebral palsy is the constant focus on preventing the damage in the brain from prohibiting healthy development on all levels. The brain, up to about the age of 8, is not concrete in its development. It has the ability to reorganize and reroute many signal paths that may have been affected by the initial trauma; the earlier it has help in doing this the more successful it will be.
Various forms of therapy are available to people living with cerebral palsy as well as caregivers and parents caring for someone with this disability. They can all be useful at all stages of this disability and are vital in a person with cerebral palsy's ability to function and live more effectively. In general, the earlier treatment begins the better chance children have of overcoming developmental disabilities or learning new ways to accomplish the tasks that challenge them. The earliest proven intervention occurs during the infant's recovery in the neonatal intensive care unit (NICU). Treatment may include one or more of the following: physical therapy; occupational therapy; speech therapy; drugs to control seizures, alleviate pain, or relax muscle spasms (e.g. benzodiazepines, baclofen and intrathecal phenol/baclofen); hyperbaric oxygen; the use of Botox to relax contracting muscles; surgery to correct anatomical abnormalities or release tight muscles; braces and other orthotic devices; rolling walkers; and communication aids such as computers with attached voice synthesizers. For instance, the use of a standing frame can help reduce spasticity and improve range of motion for people with CP who use wheelchairs.
However, there is only some benefit from therapy. Treatment is usually symptomatic and focuses on helping the person to develop as many motor skills as possible or to learn how to compensate for the lack of them. Non-speaking people with CP are often successful availing themselves of augmentative and alternative communication systems such as Blissymbols. Constraint-induced movement therapy (CIMT) has shown promising evidence in helping individuals with neurological disorders that have lost most of the use of an extremity. Research has proven the positive benefits of CIMT for people who have had a stroke and traumatic brain injury. However, later studies have addressed the application of CIMT for children with CP challenged with hemiparesis, that show a significant benefit in constraint induced movement therapy for children with cerebral palsy who are challenged with hemiparesis.
Physiotherapy programs are designed to encourage the patient to build a strength base for improved gait and volitional movement, together with stretching programs to limit contractures. Many experts believe that lifelong physiotherapy is crucial to maintain muscle tone, bone structure, and prevent dislocation of the joints.
Speech therapy helps control the muscles of the mouth and jaw, and helps improve communication. Just as CP can affect the way a person moves their arms and legs, it can also affect the way they move their mouth, face and head. This can make it hard for the person to breathe; talk clearly; and bite, chew and swallow food. Speech therapy often starts before a child begins school and continues throughout the school years.
Conductive education was developed in Hungary from 1945 based on the work of András Pető. It is a unified system of rehabilitation for people with neurological disorders including cerebral palsy, Parkinson's disease and multiple sclerosis, amongst other conditions. It is theorised to improve mobility, self-esteem, stamina and independence as well as daily living skills and social skills. The conductor is the professional who delivers CE in partnership with parents and children. Skills learned during CE should be applied to everyday life and can help to develop age-appropriate cognitive, social and emotional skills. It is available at specialized centers.
Patterning is a controversial form of alternative therapy for people with CP. The method is promoted by The Institutes for the Achievement of Human Potential (IAHP), a Philadelphia nonprofit, but has been criticized by the American Academy of Pediatrics. The IAHP's methods have been endorsed by Linus Pauling, as well as some parents of children treated with their methods.
Massage therapy is designed to help relax tense muscles, strengthen muscles, and keep joints flexible. More research is needed to determine the health benefits of these therapies for people with CP.
- Main article: Occupational therapy in the management of cerebral palsy
Occupational Therapy (OT) enables individuals with CP to participate in activities of daily living that are meaningful to them. A family-centred philosophy is used with children who have CP. Occupational therapists work closely with families in order to address their concerns and priorities for their child. Occupational therapists may address issues relating to sensory, cognitive, or motor impairments resulting from CP that affect the child's participation in self-care, productivity, or leisure. Parent counselling is also an important aspect of occupational therapy treatment with regard to optimizing the parent's skills in caring for and playing with their child to support improvement of their child's abilities to do things. The occupational therapist typically assesses the child to identify abilities and difficulties, and environmental conditions, such as physical and cultural influences, that affect participation in daily activities. Occupational therapists may also recommend changes to the play space, changes to the structure of the room or building, and seating and positioning techniques to allow the child to play and learn effectively.
Botulinum toxin A injections are given into muscles that are spastic or sometimes dystonic, the aim being to reduce the muscle hypertonus that can be painful. A reduction in muscle tone can also facilitate bracing and the use of orthotics. Most often lower extremity muscles are injected. Botulinum toxin is focal treatment meaning that a limited number of muscles can be injected at the same time. The effect of the toxin is reversible and a reinjection is needed every 4–6 months.
Surgery and orthoses
Surgery usually involves one or a combination of:
- Loosening tight muscles and releasing fixed joints, most often performed on the hips, knees, hamstrings, and ankles. In rare cases, this surgery may be used for people with stiffness of their elbows, wrists, hands, and fingers. Selective Percutaneous Myofascial Lengthening (SPML) is one example.
- The insertion of a baclofen pump usually during the stages while a patient is a young adult. This is usually placed in the left abdomen. It is a pump that is connected to the spinal cord, whereby it sends bits of Baclofen alleviating the continuous muscle flexion. Baclofen is a muscle relaxant and is often given by mouth to patients to help counter the effects of spasticity.
- Straightening abnormal twists of the leg bones, i.e. femur (termed femoral anteversion or antetorsion) and tibia (tibial torsion). This is a secondary complication caused by the spastic muscles generating abnormal forces on the bones, and often results in intoeing (pigeon-toed gait). The surgery is called derotation osteotomy, in which the bone is broken (cut) and then set in the correct alignment.
- Cutting nerves on the limbs most affected by movements and spasms. This procedure, called a rhizotomy ("rhizo" meaning root and "tomy" meaning "a cutting of" from the Greek suffix 'tomia'), reduces spasms and allows more flexibility and control of the affected limbs and joints.
Orthotic devices such as ankle-foot orthoses (AFOs) are often prescribed to minimise gait irregularities. AFOs have been found to improve several measures of ambulation, including reducing energy expenditure and increasing speed and stride length.
Cooling high-risk full-term babies shortly after birth may reduce disability or death.
Early nutritional support: In one cohort study of 490 premature infants discharged from the NICU, the rate of growth during hospital stay was related to neurological function at 18 and 22 months of age. The study found a significant decrease in the incidence of cerebral palsy in the group of premature infants with the highest growth rate. This study suggests that adequate nutrition and growth play a protective role in the development of cerebral palsy.
Hyperbaric oxygen therapy (HBOT), in which pressurized oxygen is inhaled inside a hyperbaric chamber, has been studied under the theory that improving oxygen availability to damaged brain cells can reactivate some of them to function normally. A 2007 systematic review concluded that treatment with HBOT showed no significant difference from that of pressurized room air, and that some children undergoing HBOT may experience adverse events such as seizures and the need for ear pressure equalization tubes; due to poor quality of data assessment the review also concluded that estimates of the prevalence of adverse events are uncertain.
Use of terms when referring to people with CP
Impairment is the correct term to use to define a deviation from normal, such as not being able to make a muscle move or not being able to control an unwanted movement. Disability is the term used to define a restriction in the ability to perform a normal activity of daily living which someone of the same age is able to perform. For example, a three year old child who is not able to walk has a disability because normal three year old can walk independently. Handicap is the term used to describe a child or adult who, because of the disability, is unable to achieve the normal role in society commensurate with his age and socio-cultural milieu. As an example, a sixteen-year- old who is unable to prepare his own meal or care for his own toileting or hygiene needs is handicapped. On the other hand, a sixteen-year- old who can walk only with the assistance of crutches but who attends a regular school and is fully independent in activities of daily living is disabled but not handicapped. All disabled people are impaired, and all handicapped people are disabled, but a person can be impaired and not necessarily be disabled, and a person can be disabled without being handicapped.
The term "spastic" describes the attribute of spasticity in types of spastic CP. In 1952 a UK charity called The Spastics Society was formed. The term "spastics" was used by the charity as a term for people with CP. The word "spaz" has since been used extensively as a general insult to disabled people, which some see as extremely offensive. It is also frequently used to insult able-bodied people when they seem overly anxious or unskilled in sports. The charity changed its name to Scope in 1994. In the United States the word spaz has the same usage as an insult, but is not generally associated with CP.
A common misconception about those born with Cerebral Palsy is that they are less intelligent than those born without it. Cerebral Palsy is defined as damage to the part of the brain that controls movement; areas of the brain which define a persons intelligence are not affected by CP.
Spastic Cerebral Palsy, the most common form of CP, causes the muscles to be tense, rigid and movements are slow and difficult. This can be misinterpreted as cognitive delay due to difficulty of communication. Individuals with cerebral palsy can have learning difficulties, but sometimes it is the sheer magnitude of problems caused by the underlying brain injury which prevents the individual from expressing what cognitive abilities they do possess. 
Those with CP are sometimes stigmatised and shunned. This has lessened since the 1950s thanks to public education and to United Cerebral Palsy in the U.S. and similar organisations in other countries. Prior to that time the great majority were often sent to asylums or confined to attics. They were perceived to be the products of incest and partial smotherings. [How to reference and link to summary or text] Often parents kept their children away from them in the mistaken belief that the condition was the product of disease or poor sanitary habits.
Thomas Galton believed that there was a correlation between physical disability and aptitude, and this attitude remained prevalent as concerned CP until the 1970s. At this time, CP was an overdiagnosed disorder, and a common misunderstanding then and now is that CP causes mental retardation. In fact, only CP individuals with brain damage in the hippocampus or the frontal cerebral cortex develop mental retardation. While learning difficulties and CP may co-occur, it is common for individuals with CP to lead normal lives.
