Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for neurodegenerative diseases, PTSD, and other conditions with inflammatory responses are insufficient in managing symptoms and improving cognitive function.
Innovation Solution
Administering green light therapy, specifically in the wavelength range of 515 nm to 535 nm, to subjects for extended periods, including multiple times a week, to modulate microglia activation and reduce inflammatory responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current treatments are used for neurodegenerative diseases, then symptom management is provided, but cognitive function improvement is insufficient
Solution Approach 1:
The patent changes the parameter of light wavelength to specifically green light (500-560 nm, preferably 520-540 nm) to target microglia cells. This parameter change enables simultaneous achievement of reliable symptom management and cognitive function improvement by selectively modulating microglia activation states without affecting other cell types.
2Object-generated harmful factors
If green light therapy is administered to modulate microglia activation, then inflammatory responses are reduced, but treatment duration and frequency requirements increase
Solution Approach 1:
The patent implements periodic administration of green light therapy at specific intervals (e.g., daily or several times per week) to maintain effective modulation of microglia activation. This periodic action pattern achieves sustained reduction of inflammatory responses while optimizing treatment duration by avoiding continuous exposure.
3Illumination intensity
If conventional light therapy wavelengths are used, then general illumination is provided, but specific microglia modulation is not achieved
Solution Approach 1:
The patent applies local quality by using green light with specific wavelength (500-560 nm, preferably 520-540 nm) that selectively interacts with microglia cells. This specific wavelength range penetrates the blood-brain barrier and is absorbed by cytochrome c oxidase in microglia, enabling precise modulation of these cells while leaving other brain cells unaffected.

Function Achieved in This Case
Green light therapy has shown potential in reducing symptoms of neurodegenerative diseases, improving cognitive function, and alleviating anxiety and PTSD symptoms by modulating microglia activation and reducing chronic inflammation.
Implementation Method 1
administering green light to subjects for managing or minimizing cognitive deficits or memory impairments, as well as reducing the symptoms associated with posttraumatic stress disorder (PTSD), anxiety and neurodegenerative diseases
Implementation Method 2
light with one or more wavelengths in the range between approximately 515 nm and approximately 535 nm to a retina of a subject

AI summary
Methods, systems and devices for administering green light to subjects are described. The described techniques can be used for managing cognitive deficits or memory impairments, reducing the symptoms associated with posttraumatic stress disorder (PTSD), anxiety and neurodegenerative diseases and other conditions. One example method for managing or minimizing cognitive deficits or memory impairments includes administering, for a first time period and according to a pre-arranged schedule of administrations, light with one or more wavelengths in the range between approximately 515 nm and approximately 535 nm to a retina of a subject. The method further includes administrating the light, for a second time and subsequent periods according to the pre-arranged schedule of administrations to the retina of the subject. The first, the second and the subsequent time periods occur on separate days, and the pre-arranged schedule of administrations includes administrations that span over at least one week.
