The team usually works under the supervision of a neurologist or rehabilitation physician directing treatment goals.Physiotherapy interventions include strength, endurance, and gait training with graduated increases in mobility, maintenance of posture and alignment as well as joint function. Occupational therapy aims to improve everyday function with domestic and community tasks as well as driving and work. Home modifications, gait aids, orthotics, and splints may be provided. Speech-language pathology input may be required in those with speech and swallowing problems, as well as to support communication in those who require ongoing breathing support (often through a tracheostomy). Nutritional support may be provided by the team and by dietitians. Psychologists may provide counseling and support. Psychological interventions may also be required for anxiety, fear, and depression. Prognosis
Guillain–Barré syndrome can lead to death as a result of many complications: severe infections, blood clots, and cardiac arrest likely due to autonomic neuropathy. Despite optimum care, this occurs in about 5% of cases.There is a variation in the rate and extent of recovery. The prognosis of Guillain–Barré syndrome is determined mainly by age (those over 40 may have a poorer outcome), and by the severity of symptoms after two weeks. Furthermore, those who experienced diarrhea before the onset of the disease have a worse prognosis. On the nerve conduction study, the presence of conduction block predicts poorer outcome at 6 months.
Intravenous immunoglobulins were introduced in 1988, and studies in the early 1990s demonstrated that they were no less effective than plasma exchange. Research directions
The understanding of the disease mechanism of Guillain–Barré syndrome has evolved in recent years. Development of new treatments has been limited since immunotherapy was introduced in the 1980s and 1990s. Current research is aimed at demonstrating whether some people who have received IVIg might benefit from a second course if the antibody levels measured in blood after treatment have shown only a small increase. Studies of the immunosuppressive drugs mycophenolate mofetil, brain-derived neurotrophic factor and interferon beta (IFN-β) have not demonstrated benefit to support their widespread use.An animal model (experimental autoimmune neuritis in rats) is often used for studies, and some agents have shown promise: glatiramer acetate, quinpramine, fasudil (an inhibitor of the Rho-kinase enzyme), and the heart drug flecainide. An antibody targeted against the anti-GD3 antiganglioside antibody has shown benefit in laboratory research. Given the role of the complement system in GBS, it has been suggested that complement inhibitors (such as the drug eculizumab) may be effective. In animals it is called acute polyradiculoneuritis or "coonhound paralysis", and may onset in the coonhound 7 to 10 days after transmission from raccoons. If the coonhound has not been around raccoons, the disease is called acute idiopathic polyradiculoneuritis. References
