40 Hz Flicker Display Therapy for Alzheimer's Beta Amyloid Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for Alzheimer's disease and dementia, such as flashing light therapy and cognitive training, are less effective when used alone, and existing display technologies with 60 Hz refresh rates do not easily accommodate the 40 Hz frequency required for optimal beta amyloid reduction.
Innovation Solution
Combining flashing light therapy with cognitive training on a mobile or stationary device screen, using an LED frame or light source to generate 40 Hz frequency, which can be integrated with modern displays or other devices to provide synchronized light and cognitive therapy, motivating patients to maintain focus on the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a 60 Hz refresh rate display is used, then the display is compatible with modern devices, but the 40 Hz frequency required for optimal beta amyloid reduction cannot be achieved
Solution Approach 1:
The system dynamically adjusts display parameters based on the desired 40 Hz frequency. Instead of using a fixed 60 Hz refresh rate, the display dynamically presents lighter and darker frames in varying proportions (e.g., 2 lighter frames followed by 3 darker frames at 60 Hz) to achieve the target 40 Hz flicker frequency that stimulates 40 Hz gamma waves in the brain.
Solution Approach 2:
The invention changes the temporal parameters of light presentation by controlling the duration and sequence of lighter and darker frames. By adjusting the percentage of time spent in lighter versus darker states within each refresh cycle, the system transforms the display's output frequency from the fixed 60 Hz to the therapeutic 40 Hz range, maintaining compatibility with modern displays while achieving the required frequency precision.
2Reliability
If flashing light therapy is used alone, then beta amyloid reduction is achieved, but patient motivation and engagement are insufficient
Solution Approach 1:
The system merges flashing light therapy with cognitive training activities into a single integrated experience. Cognitive tasks such as puzzles, memory games, or educational content are displayed on the screen while the same display simultaneously delivers the 40 Hz light flicker therapy. This combination ensures patients remain engaged and motivated to complete cognitive exercises while receiving continuous light therapy, thereby improving compliance without compromising therapeutic effectiveness.
3Ease of operation
If cognitive training activities are used alone, then patient engagement is maintained, but beta amyloid reduction effectiveness is reduced
Solution Approach 1:
The system merges cognitive training activities with flashing light therapy into a single integrated experience. Cognitive tasks such as puzzles, memory games, or educational content are displayed on the screen while the same display simultaneously delivers the 40 Hz light flicker therapy. This combination ensures patients remain engaged and motivated to complete cognitive exercises while receiving continuous light therapy, thereby improving compliance without compromising therapeutic effectiveness.
4Reliability
If an LED frame is added around the screen, then 40 Hz light therapy is provided, but device complexity increases
Solution Approach 1:
The invention makes the display screen perform multiple functions simultaneously: it delivers cognitive training content, maintains patient engagement, and generates 40 Hz light flicker for therapeutic effect. By controlling the timing and brightness of display frames, the single device accomplishes what would otherwise require separate components (cognitive training system plus external light therapy device), thereby reducing overall system complexity while maintaining therapeutic reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The combined therapy effectively reduces beta amyloid proteins by promoting natural 40 Hz gamma waves, enhancing brain function and symptom reduction for Alzheimer's and dementia patients, outperforming solo therapies.
Implementation Method 1
The flashing light, for example, at about 40 Hz, may be generated by a LED frame or another light source next to or around the screen
Implementation Method 2
They assure that a patient is looking at the flickering display. or a flickering light source next to it. or around it and thus receives the flashing light therapy with open eyes. Furthermore, the cognitive activities promote the natural 40 Hz gamma waves generated by the patient's own neural networks
