PBM is widely used to treat conditions related to neurogenesis. It improves post-stroke local microenvironment and stimulates neuroprogenitor cells, significantly alleviating behavioral deficits after PT stroke. Red light therapy has even been shown to stimulate so-called mesenchymal stem cells in bone marrow to enhance their capacity to infiltrate the brain. This has implications for healing degenerative conditions such as dementia, Alzheimer’s and Parkinson’s disease – conditions currently lacking any orthodox treatment solution.
