BRP is an enigmatic condition with a controversial cause; some authors consider BRP to be a photodermatosis, whereas other authors attribute BRP to compression of cervical nerve roots. BRP may be attributed to a neuropathy, such as chronic cervical radiculopathy. The possibility of an underlying neuropathy should be considered in the evaluation and treatment of all patients with BRP.The main cause of BRP is not known, but there is evidence to suggest that BRP may arise in the nervous system. Cervical spine disease may also be an important contributing factor. Patients with BRP may have underlying cervical spine pathology. Whether this association is causal or coincidental remains to be determined. There is controversy regarding the cause of brachioradial pruritus: is it caused by a nerve compression in the cervical spine or is it caused by a prolonged exposure to sunlight?In many patients, itching of the arms or shoulders is seasonal. Some patients reported neck pain.BRP can be linked to the thyroid. Diagnosis
Treatments
Symptom management may include the application of a unique prescription topical combination of ketamine .5% and amitriptyline hydrochloride 1%. [2]
Milder cases may use lidocaine or capsaicin, and/or cervical traction. Treatment with lamotrigine has been reported. Treatment by acupuncture has been reported.Treatment with Gabapentin has been reported. See also

Freud also made a rough correlation between the location of the problem inside the brain and the location of the affected limbs on the body and documented the many kinds of movement disorders.In the early 20th century, the attention of the medical community generally turned away from CP until orthopedic surgeon Winthrop Phelps became the first physician to treat the disorder. He viewed CP from a musculoskeletal perspective instead of a neurological one. Phelps developed surgical techniques for operating on the muscles to address issues such as spasticity and muscle rigidity. Hungarian physical rehabilitation practitioner András Pető developed a system to teach children with CP how to walk and perform other basic movements. Petős system became the foundation for conductive education, widely used for children with CP today. Through the remaining decades, physical therapy for CP has evolved, and has become a core component of the CP management program.In 1997, Robert Palisano et al. introduced the Gross Motor Function Classification System (GMFCS) as an improvement over the previous rough assessment of limitation as either mild, moderate, or severe. The GMFCS grades limitation based on observed proficiency in specific basic mobility skills such as sitting, standing, and walking, and takes into account the level of dependency on aids such as wheelchairs or walkers. The GMFCS was further revised and expanded in 2007. Society and culture
Economic impact
It is difficult to directly compare the cost and cost-effectiveness of interventions to prevent cerebral palsy or the cost of interventions to manage CP.
