Low level light therapy for enhancement of neurologic function of a patient affected by Parkinson's disease
First Claim
1. A method of treating a subject having neurologic function affected by Parkinson'"'"'s disease, the method comprising:
- identifying a subject having neurologic function affected by Parkinson'"'"'s disease; and
delivering electromagnetic radiation noninvasively through the scalp and the skull of the subject to at least one portion of the brain of the subject, the electromagnetic radiation having a wavelength in the visible to near-infrared wavelength range, wherein the wavelength, power density, and amount of the electromagnetic radiation delivered to the at least one portion of the brain are sufficient to reduce the severity of symptoms of Parkinson'"'"'s disease in the subject, wherein the power density of the electromagnetic radiation delivered to the at least one portion of the brain is at least 0.01 mW/cm2, wherein delivering the electromagnetic radiation comprises;
identifying at least about 10 treatment sites on the subject'"'"'s scalp;
directing an electromagnetic radiation source to each of the treatment sites; and
propagating electromagnetic radiation from the source to each treatment site, the electromagnetic radiation having a wavelength within a range between about 800 nanometers and about 830 nanometer.

Abstract
A method of treating a patient having neurologic function affected by Parkinson'"'"'s disease is provided. The method includes providing a patient having neurologic function affected by Parkinson'"'"'s disease. The method further includes delivering electromagnetic radiation noninvasively through the scalp and the skull of the patient to at least one portion of the brain of the patient. The light energy has a wavelength in the visible to near-infrared wavelength range, and the wavelength, power density, and amount of the light energy delivered to the at least one portion of the brain are sufficient to reduce the severity of symptoms of Parkinson'"'"'s disease in the patient.
