It is common to use gangliosides to treat cerebral palsy, brain injury, post-encephalitis and other pediatric neurological disorders, but what are the specific effects? Some children use it for 3-4 courses of treatment, but the effect is not particularly satisfactory, what are the reasons? First of all, it is important to know the role of gangliosides. Tetrahexose monosialate ganglioside sodium salt injection has been widely used clinically at home and abroad. Tetrahexose monosialate ganglioside sodium salt injection can promote the normal development of nerve cells and brain tissue, prevent and control cerebral palsy and other diseases; repair damage to nerves and brain tissue and other diseases. Brain damage is mainly caused by premature birth, low weight, asphyxia, jaundice, etc. Brain cells are above 100 billion and will not increase, using an estimated one-tenth. Once the brain cells die, they will not regenerate. It mainly relies on compensatory function and repair of nerve cells and the connection between nerve cells, i.e. synapses and dendrites, etc. Therefore, cerebral palsy or brain injury syndrome generally relies on functional training to improve the compensatory capacity of the brain, peripheral stimulation to improve abnormal posture through nerve conduction and neurofeedback, together with the repairing effect of drugs. Ganglioside is effective in treating cerebral palsy, but it is not the main treatment method, so it is not recommended to rely on infusion to treat cerebral palsy or brain injury syndrome. The treatment of cerebral palsy and brain injury syndrome is mainly rehabilitation, mainly functional training, together with physical factor therapy (electrotherapy, wax therapy, magnetic heat therapy, etc.), drugs (rat nerve growth factor, ganglioside, vitamin B1, vitamin B12, brain rejuvenation, etc.), and traditional therapy (acupuncture, acupuncture point injection, tui na, buried thread, etc.).
