There is no known cure for cerebral palsy, however there is a large array of treatments proven effective at improving quality of life and relieving some of the symptoms associated with CP, especially SHCP. Some treatments are aimed at improving mobility, strengthening muscle and improving coordination. Although CP is due to permanent damage and is not progressive in nature, without treatment the symptoms can become worse, intensifying in pain and severity, and create complications that were not initially present. Some treatments are preventative measures to help prevent further complications, such as complete paralysis of the arm due to non-use and subsequent worsening hypertonia and joint contracture. Others forms of treatment are corrective in nature. Many treatments target symptoms that are indirectly related to or caused by the SHCP. Many of these treatments are common for other forms of CP as well. Treatment is individualized based on each case and the specific needs of the patient. Treatments are often combined with other forms of treatment and a long term treatment plan is created and continuously evaluated. Treatment can include the following:

- "Physical therapy" – Physical therapy is the most common form of treatment (source needed). It may include sensory stimulation, stretching, strengthening and positioning. Constraint-induced movement therapy is a newer form of physical therapy for SHCP that involves casting or splinting the unaffected arm to promote use of the affected arm (Taub). The theory behind constraint-induced movement therapy is that new neural pathways are created. Alternative forms of physical therapy include yoga and dance. Physical therapy may also include the use of braces while not actively involved with the therapist.

- "Occupational therapy" – Occupational therapy evaluates and treats patients through selected activities in order to enable people to function as effectively and independently as possible in daily life. Occupational therapy is geared toward the individual to achieve optimal results and performance while learning to cope with their disability.

- "Speech therapy" – Due to difficulties in speech, speech therapy is often necessary. Aside from helping with understanding language and increasing communication skills, speech therapists can also assist children that have difficulty eating and drinking.

- "Behavioral therapy" — Psychotherapy and counseling are heavily used in treatment of individuals with SHPD to help them cope emotionally with their needs and frustrations. Counseling through social work can be very beneficial for social issues and adjustments to society. Psychotherapy becomes a more important aspect of therapy when more serious issues such as depression become problematic. Play therapy is a common treatment for all young children with or without disabilities, but can be very useful helping children with SHCP. This therapy again is individualized geared to improve emotional and social development; reduce aggression; improve cooperation with others; assist a child in processing a traumatic event or prepare for an upcoming event such as surgery.

- "Surgery" – Although surgery may become necessary in some cases, physical therapy and the consistent use of braces can help mitigate the need for surgery. Surgical procedures are painful with long and difficult recoveries and do not cure the condition. Most common, is surgery that effectively lengthens the muscle. This type of surgery is usually performed on the legs, but can be performed on the arms as well. Surgeries also may be necessary to realign joints. Other, less popular surgical techniques try to reduce spasticity by severing selected overactive nerves that control muscles. This procedure, known as selective dorsal root rhizotomy, is still somewhat controversial, and is generally used only on the lower extremities of severe cases. Other experimental surgical techniques are also being investigated. The benefits of surgery can also be negated or reversed if the patient does not participate in physical therapy and braces (or casts) are not worn regularly.

- "Medicinal" – Medication targeting symptoms associated with spasticity is also a relatively new treatment that is utilized, but is still in the early stages of development. Drugs such as baclofen, benzodiazepines (e.g., diazepam), tizanidin, and sometimes dantrolene have shown promise in the effort to diminish spasticity. Botulinum toxin ("Botox") type A may reduce spasticity a few months at a time and has frequently been considered a beneficial treatment for children with SHCP and other forms of CP. Botox has been shown to be especially beneficial to reducing spasticity in the gastrocnemius (calf) muscle. This therapy can improve range of motion, reduce deformity, improve response to occupational and physical therapy, and delay the need for surgery. Botox injections have also shown advantages for upper extremities. There is still some doubt for the effectiveness, and some side effects to the relaxed muscles have been a loss of strength for patients with some muscle control. Casting, in conjunction with Botox injections may be an additional option for better results. Research is constantly investing in new improvements and more experimental therapy and treatment.

Drugs can be used to treat issues related to the Upper Motor Neuron Syndrome. Drugs like Librium or Valium could be used as a relaxant. Drugs are also given to individuals who have recurrent seizures, which may be a separate but related problem after brain injury.

Rehabilitation is the main treatment of individuals with hemiplegia. In all cases, the major aim of rehabilitation is to regain maximum function and quality of life. Both physical and occupational therapy can significantly improve the quality of life.

Sleep is also used as a management technique. An early indication of an episode is tiredness so medication such as melatonin or Buccal midazolam can be administered to induce sleep and avoid the episode.

Those suffering from alternating hemiplegia are often underweight and with the help of dietitians, a meal plan should be developed for times of attack when consumption of food may be difficult.

There are several different modes of treatment for people with paralysis in their upper limbs. For example, behavioral and environmental treatments may include physiotherapy, occupational therapy, motor learning, strength training, and neurodevelopment treatment. Another treatment may be through the use of splints and casts. Electrophysical agents may be used such as neuromuscular electrical stimulation (NMES). Sometimes pharmacological treatments are necessary such as Botulinum toxin type A. On more severe cases surgery of the upper limbs may be required.

Many children affected by alternating hemiplegia also suffer from epilepsy. Seizures may occur during an attack but more often occur between attacks. Anti-epilepsy drugs are given to prevent or lessen the seizures, but the drugs often don’t work and have severe side effects that require the patient to discontinue use. Flunarizine, which blocks calcium channels, is an antiepilepsy drugs used in 50% of patients, and has been shown to shorten the duration of attacks as well as reducing the severity of the attacks. While Flunarizine does not stop the attacks, it is most common drug prescribed to treat those suffering from alternating hemiplegia.

Doublecortin positive cells, similar to stem cells, are extremely adaptable and, when extracted from a brain, cultured and then re-injected in a lesioned area of the same brain, they can help repair and rebuild it. The treatment using them would take some time to be available for general public use, as it has to clear regulations and trials.

There are several ways of getting diplegia in the arms. It is very common for people with Cerebral Palsy to have diplegia of the arms. Although most people with Cerebral Palsy have diplegia in their legs, some people have diplegia in their arms. Other ways of getting paralysis of both arms is through a traumatic event or injury.

The muscle spasticity can cause gait patterns to be awkward and jerky. The constant spastic state of the muscle can lead to bone and tendon deformation, further complicating the patient's mobility. Many patients with spastic hemiplegia are subjected to canes, walkers and even wheelchairs. Due to the decrease in weight bearing, patients are at a higher risk of developing osteoporosis. An unhealthy weight can further complicate mobility. Patients with spastic hemiplegia are a high risk for experiencing seizures. Oromotor dysfunction puts patients at risk for aspiration pneumonia. Visual field deficits can cause impaired two-point discrimination. Many patients experience the loss of sensation in the arms and legs on the affected side of the body. Nutrition is essential for the proper growth and development for a child with spastic hemiplegia.

In any manifestation of spastic CP, clonus of the affected limb(s) may intermittently result, as well as muscle spasms, each of which results from the pain and/or stress of the tightness experienced, indicating especially hard-working and/or exhausted musculature. The spasticity itself can and usually does also lead to very early onset of muscle-stress symptoms like arthritis and tendinitis, especially in ambulatory individuals in their mid-20s and early-30s. As compared to other types of CP, however, and especially as compared to hypotonic CP or more general paralytic mobility disabilities, spastic CP is typically more easily manageable by the person affected, and medical treatment can be pursued on a multitude of orthopaedic and neurological fronts throughout life.

Physical therapy and occupational therapy regimens of assisted stretching, strengthening, functional tasks, and/or targeted physical activity and exercise are usually the chief ways to keep spastic CP well-managed, although if the spasticity is too much for the person to handle, other remedies may be considered, such as various antispasmodic medications, botox, baclofen, or even a neurosurgery known as a selective dorsal rhizotomy (which eliminates the spasticity by eliminating the nerves causing it).

Treatment is directed at the pathology causing the paralysis. If it is because of trauma such as a gunshot or knife wound, there may be other life-threatening conditions such as bleeding or major organ damage which should be dealt with on an emergent basis. If the syndrome is caused by a spinal fracture, this should be identified and treated appropriately. Although steroids may be used to decrease cord swelling and inflammation, the usual therapy for spinal cord injury is expectant.

The most common drug used to treat AHC is flunarizine. Flunarizine functions by acting as a calcium channel blocker. Other drugs, in order of frequency of use are benzodiazepines, carbamazapine, barbiturates, and valproic acid. Flunarizine is prescribed for the purpose of reducing the severity of AHC attacks and the number of episodes, though it rarely stops attacks altogether. Minimizing the attacks may help reduce damage to the body from hemiplegic attacks and improve long-term outcomes as far as mental and physical disabilities are concerned.

Experts differ in their confidence in flunarizine's effectiveness. Some studies have found it to be very effective in reducing the duration, severity, and frequency of hemiplegic attacks. It is generally considered the best treatment available, but this drug is thought by some to be of little benefit to AHC patients. Many patients suffer adverse effects without seeing any improvement. Flunarizine also causes problems because it is difficult for patients to obtain, as it is not readily available in the United States.

Spastic quadriplegia, also known as spastic tetraplegia, is a subset of spastic cerebral palsy that affects all four limbs (both arms and legs).

Compared to quadriplegia, spastic tetraplegia is defined by spasticity of the limbs as opposed to strict paralysis. It is distinguishable from other forms of cerebral palsy in that those afflicted with the condition display stiff, jerky movements stemming from hypertonia of the muscles.

Spastic quadriplegia, while affecting all four limbs more or less equally, can still present parts of the body as stiffer than others, such as one arm being tighter than another arm, and so forth. Spastic triplegia, meanwhile, involves three limbs (such as one arm and two legs, or one leg and two arms, etc.); spastic diplegia affects two limbs (commonly just the legs), spastic hemiplegia affects one or another entire side of the body (left or right); and spastic monoplegia involves a single limb.

Spastic cerebral palsy is the type of cerebral palsy wherein spasticity is the exclusive impairment present. Itself an umbrella term encompassing spastic hemiplegia, spastic diplegia, spastic quadriplegia and — where solely one limb or one specific area of the body is affected— spastic monoplegia. Spastic cerebral palsy affects the cerebral cortex it is overwhelmingly the most common type of overall cerebral palsy.

The Society for Cerebral Palsy in Europe (SCPE) estimates that the spasticity-only cerebral palsy classification sweeps in 90% of global cerebral palsy cases. But even if the 90% assertion is an exaggeration, more conservative scientific estimates still place the prevalence of spasticity-dominant or spasticity-only cerebral palsy at anywhere from 70–80% of all cases, leaving cases dominated by ataxic cerebral palsy, dyskinetic cerebral palsy and athetoid cerebral palsy trailing at 20–30%.

Mild cases are managed by limiting activity, keeping a healthy body weight, and avoiding exposure to high ambient temperatures. Mild sedatives can be used to decrease anxiety and panting and therefore improve respiration. Corticosteroids may also be administered in acute cases to decrease inflammation and edema of the larynx.

Severe acute symptoms, such as difficulty breathing, hyperthermia, or aspiration pneumonia, must be stabilized with sedatives and oxygen therapy and may require steroid or antibiotic medications. Sometimes a tracheotomy is required to allow delivery of oxygen. Once the patient is stabilized, surgical treatment may be beneficial especially when paralysis occurs in both aretynoid cartilages (bilateral paralysis). The surgery (aretynoid lateralization, or a "laryngeal tieback") consists of suturing one of the aretynoid cartilages in a maximally abducted (open) position. This reduces the signs associated with inadequate ventilation (such as exercise intolerance or overheating) but may exacerbate the risk of aspiration and consequent pneumonia. Tying back only one of the aretynoid cartilages instead of both helps reduce the risk of aspiration. Afterwards the dog will still sound hoarse, and will need to be managed in the same way as those with mild cases of LP.

Recent studies have found that many dogs with laryngeal paralysis have decreased motility of their esophagus. Animals with a history of regurgitation or vomiting should be fully evaluated for esophageal or other gastrointestinal disorders. Dogs with megaesophagus or other conditions causing frequent vomiting or regurgitation are at high risk for aspiration pneumonia after laryngeal tie-back. Permanent tracheostomy is an alternative surgical option for these dogs to palliate their clincical signs.

Current research at the University of Utah is investigating whether sodium oxybate, also known as Gamma-Hydroxybutyric acid is an effective treatment for AHC. Thus far, only a small number of patients have been sampled, and no conclusive results are yet available. While some success has been had thus far with the drug, AHC patients have been known to respond well initially to other drugs, but then the effectiveness will decline over time. Currently, sodium oxybate is used as a narcolepsy-cataplexy treatment, though in the past it has been used controversially in nutritional supplements. This drug was chosen to test because of a possible link between the causes of narcolepsy-cataplexy and AHC.

Currently, there is no cure for porencephaly because of the limited resources and knowledge about the neurological disorder. However, several treatment options are available. Treatment may include physical therapy, rehabilitation, medication for seizures or epilepsy, shunt (medical), or neurosurgery (removal of the cyst). According to the location, extent of the lesion, size of cavities, and severity of the disorder, combinations of treatment methods are imposed. In porencephaly patients, patients achieved good seizure control with appropriate drug therapy including valproate, carbamazepine, and clobazam. Also, anti-epileptic drugs served as another positive method of treatment.

Triplegia is a medical condition characterized by the paralysis of three limbs (Triplegia Muscle Anatomy) . A person with triplegia can be referred to as triplegic. While there is no typical pattern of involvement, it is usually associated with paralysis of both legs and one arm — but can also involve both arms and one leg. Triplegia can sometimes by considered a combination of hemiplegia (paralysis of arm and leg of one side of the body) overlaying diplegia (paralysis of both legs), or as quadriplegia (paralysis of four limbs) with less involvement in one extremity.

The condition is commonly associated with cerebral palsy, although conditions such as stroke can also lead to it. Triplegia has also been found to be due to an increase in intracranial pressure associated with hydrocephalus resulting from traumatic brain injury.

A similar condition is triparesis, in which the patient suffers from paresis in three limbs, meaning that the limbs are very weak, but not completely paralyzed.

In a case reported only due to its rarity, triplegia was reported following a tonsillectomy (surgical removal of the tonsils). An eight-year-old male patient was sent to Willard Parker Hospital on August 12, 1929 and had been diagnosed with poliomyelitis. After an unrelated, and routine, tonsillectomy there was complete flaccid paralysis and loss of feeling in both the legs, right arm, and muscles in the trunk.

There is no treatment for Todd's paralysis. Individuals must rest as comfortably as possible until the paralysis disappears.

Treatment of all categories of congenital clasped thumbs should start with either serial plaster casting or wearing a static or dynamic splint for a period of six months, while massaging the hand. Extension by splinting shows reduction of the flexion contracture. To gain optimal results, it is important to start this treatment before the age of six months. The result of this therapy is better in less severe deformities. In most uncomplicated cases, a satisfactory result can be gained when splint therapy starts before the age of six months. Splinting should be tried for at least three months and possibly for as long as six months or longer. If the result of splint therapy stagnates, surgery treatment is indicated.

Congenital fourth cranial nerve palsy can be treated with strabismus surgery, where muscle attachment sites on the globe are modified to realign the eyes. Some eye doctors prefer conservative or no management of congenital fourth nerve palsy.

Other eye doctors recommend surgery early in a patient's life to prevent the compensatory torticollis and facial asymmetry that develop with age.

Prism lenses set to make minor optical changes in the vertical alignment may be prescribed instead of or after surgery to fine-tune the correction. Prism lenses do not address torsional misalignment and this may limit their use in certain cases. An additional consideration of prism lenses is that they must be worn at all times. Prism lenses reduce vertical fusional demands by allowing the eyes to rest in their vertically misaligned state. When they are removed the patient may experience vertical diplopia they find hard to resolve due to the rested state of their eyes.

Cases of congenital fourth nerve palsy vary in magnitude and way they affect the motion of the superior oblique muscle. Therefore different surgeries are available dependent upon the type of misalignment. Sometimes surgery on more than one eye muscle is required. In some simpler, unilateral cases a single surgery may suffice. In these cases the main problem is that the inferior oblique muscle of the same eye acts unopposed by the weakened superior oblique muscle, pulling the eye up. An example of a safe and effective procedure is a disinsertion of the inferior oblique muscle to allow it to reattach itself further down the globe of the eye. This acts to 'weaken' its action and allow the eye to move back into a more neutral alignment.

In all cases of congenital fourth nerve palsy, it is important to see an experienced strabismologist about management/treatment options. A strabismologist is an ophthalmologist (eye doctor) specialising in eye movement disorders.

Treatment generally includes the following:

- Sometimes pharmacologic therapy for initial disease treatment

- Physical therapy

- Occupational therapy

- Use of appropriate assistive devices such as orthoses

- Surgical treatment

Treatment of congenital clasped thumb includes two types of therapy: conservative and surgical.

Besides complications of surgery and anesthesia in general, there may be drainage, swelling, or redness of the incision, gagging or coughing during eating or drinking, or pneumonia due to aspiration of food or liquids. Undesirable complications are estimated to occur in 10-30% of cases. If medical therapy is unsuccessful and surgery cannot be performed due to concurrent disease (such as heart or lung problems) or cost, euthanasia may be necessary if the animal's quality of life is considered unacceptable due to the disease.

Treatment for autosomal dominant porencephaly type I is based on the symptoms that an individual is experiencing - for example, treatment of seizures with anticonvulsants. It is particularly important for individuals with this disorder and hypertension to control their blood pressure, as they are at higher risk of stroke. Other stroke prevention treatments include avoiding anticoagulants, smoking, and situations that may lead to head trauma.
