Near infrared LEDs and lasers used on the head have been shown to have positive effects in dementia patients by decreasing inflammation in the brain and promoting synaptogenesis and neurogenesis: creation of new synapses and neurons in the brain. Light therapy, or photobiomodulation, also improved quality of life for dementia patients by promoting longer, peaceful sleep, improved memory recall and improved visual motor coordination.
