Systems and methodologies for treating or preventing psychiatric disorders, brain trauma, and addiction or dependence by light therapy with modulated frequency

A method for treating a subject suffering from a traumatic brain injury, comprising:

• diagnosing the subject as suffering from a traumatic brain injury;
• providing a light therapy unit comprising (a) a chassis, (b) a plurality of LEDs disposed on said chassis, and (c) a controller which controls the operation of said LEDs;
• and
• operating the plurality of LEDs at a plurality of distinct wavelengths of light such that the light emitted by the LEDs impinges on the subject, and such that at least one of the plurality of distinct wavelengths of light is modulated at a frequency within the range of about 20 Hz to about 60 Hz.

A method for treating a subject suffering from an opioid addiction, comprising:

• diagnosing the subject as suffering from an opioid addiction;
• providing a light therapy unit comprising (a) a chassis, (b) a plurality of LEDs disposed on said chassis, and (c) a controller which controls the operation of said LEDs;
• and
• operating the plurality of LEDs at a plurality of distinct wavelengths of light such that the light emitted by the LEDs impinges on the subject, and such that at least one of the plurality of distinct wavelengths of light is modulated at a frequency within the range of about 20 Hz to about 60 Hz.

A method for treating a subject suffering from ADHD, comprising:

• diagnosing the subject as suffering from ADHD;
• providing a light therapy unit comprising (a) a chassis, (b) a plurality of LEDs disposed on said chassis, and (c) a controller which controls the operation of said LEDs;
• and
• operating the plurality of LEDs at a plurality of distinct wavelengths of light such that the light emitted by the LEDs impinges on the subject, and such that at least one of the plurality of distinct wavelengths of light is modulated at a frequency within the range of about 20 Hz to about 60 Hz.

A method for treating a subject suffering from PTSD, comprising:

• diagnosing the subject as suffering from PTSD;
• providing a light therapy unit comprising (a) a chassis, (b) a plurality of LEDs disposed on said chassis, and (c) a controller which controls the operation of said LEDs;
• and
• operating the plurality of LEDs at a plurality of distinct wavelengths of light such that the light emitted by the LEDs impinges on the subject, and such that at least one of the plurality of distinct wavelengths of light is modulated at a frequency within the range of about 20 Hz to about 60 Hz.
