A system that provides neuroprotection or neuroregeneration to biological tissue includes a pulsed energy having energy parameters including a wavelength or frequency, a duty cycle and a pulse train duration. A delivery device applies the pulsed energy to neural elements of the target tissue having a chronic progressive disease or at risk of having a chronic progressive disease. The delivery device applies the pulsed energy for a predetermined total pulse train duration such that the target tissue temperature is raised sufficiently to provide neuroprotection or neuroregeneration to the neural elements of the target tissue, while maintaining the average temperature rise of the target tissue at or below a predetermined level so as not to permanently damage the target tissue.

Systems and methods for phototherapeutic modulation of nitric oxide in mammalian tissue include use of a first wavelength and first radiant flux of light to stimulate enzymatic generation of nitric oxide, and use of a second wavelength and second radiant flux of light to stimulate release of nitric oxide from endogenous stores of nitric oxide. Pulsed light and/or partially non-overlapping light impingement windows may be used. Non-coherent light impinged on tissue may include a peak wavelength in a range of from 410 nm to 440 nm in the absence of light emissions having a peak wavelength of from 600 nm to 900 nm.
