Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ultrasonic therapy for degenerative dementia is time-consuming and expensive due to the need for multiple hospital visits and the use of MRI machines to accurately target treatment zones, and existing treatments for amyloid plaque are ineffective or minimally effective.
Innovation Solution
A transducer system using low intensity focused ultrasound pulsation (LIFUP) that simulates deep sleep brain rhythms to open interstitial spaces, stimulate astrocyte cells, and remove amyloid plaque by applying ultrasonic waves during natural or sedated sleep, utilizing anatomical and functional MRI targeting and non-invasive attachment methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ultrasonic therapy is applied to treat degenerative dementia, then amyloid plaque removal is achieved, but treatment time and cost increase due to multiple hospital visits and MRI machine usage
Solution Approach 1:
The system performs preliminary anatomical mapping and treatment zone identification using MRI before the actual ultrasonic therapy sessions. Once the target areas are identified and the treatment parameters are established, the same treatment can be repeatedly applied without requiring repeated MRI scans, thereby reducing treatment time while maintaining effectiveness
Solution Approach 2:
The system creates a digital model or map of the patient's brain anatomy and treatment zones based on initial MRI scans. This digital copy allows for repeated treatment sessions to be precisely targeted without requiring repeated physical MRI scans, thus reducing both time and cost while maintaining treatment accuracy

3Reliability
If LIFUP device is used to simulate deep sleep brain rhythms, then glymphatic flow is enhanced and plaque removal is improved, but device complexity increases
Solution Approach 1:
The LIFUP device applies ultrasonic pulsation in periodic cycles that simulate natural deep sleep brain rhythms. By using periodic rather than continuous ultrasonic delivery, the device achieves enhanced glymphatic flow and improved plaque removal while managing energy consumption and simplifying control mechanisms
Solution Approach 2:
The device modulates ultrasonic parameters such as intensity, frequency, and pulse duration to match physiological sleep rhythms. By dynamically adjusting these parameters rather than using fixed settings, the system achieves therapeutic effectiveness while maintaining manageable device complexity through programmable control

AI summary
Ultrasonic energy is used for treating degenerative dementia. A focal point of an ultrasonic transducer beam is directed at a target area of the brain to promote removal of substances that accumulate in the interstitial pathways that are at least partially responsible for the degenerative dementia. In one example, the target area of the brain may comprise the hippocampus and the degenerative dementia may be Alzheimer's disease. The ultrasonic beam may stimulate brain tissue at a frequency that corresponds to a naturally occurring deep sleep burst frequency of neurons and subsequent astrocyte activation patterns that drive a convective process responsible for brain solute disposal. For example, the transducer may generate a burst frequency of between 1-4 hertz to stimulate deep sleep brain functions that help remove amyloid plaque.
