After brain damage caused by injury there is always a chance of recovery to varying degrees. Sound Therapy is an intervention which may increase the probability of a faster and more total recovery. The sooner it is introduced after the injury or stroke, the greater the likelihood of healing. Some stroke patients who use Sound Therapy have been seen to make an unexpectedly quick recovery, often with functioning returned to a surprisingly high level.
After brain damage the brain is faced with having to develop new pathways or re-route information to compensate for the damaged area. It has been proven that sensory stimulation can assist in developing new pathways. Sound Therapy is an intensive from of stimulation which is very easy to administer. Therefore Sound Therapy may be effective in helping to create new brain pathways and reforming essential connections between more distant parts of the brain. The complex, multilayered harmonic and melodic information within the classical music stimulates many parts of the brain, helping to build form and structure which assists with various forms of sensory processing.
Sound Therapy is thought to improve integration in the cerebellum, an area near the brain stem which controls many automatic functions and overall sensory and motor integration. The filtering which causes sudden bursts of high frequency sound stimulates increased firing of neurons. When a neuron fires, it sends a message to other neurons in both chemical and electrical form. Often the process of firing off a message also creates new inter-neuronal connections called dendrites or axons. This means that using Sound Therapy may build new brain connections, increasing the neural network. This is exactly what is needed to recover from a stroke or brain damage.
