Systems and methods for preventing, mitigating, and / or treating dementia
Inducing synchronized gamma oscillations in the brain using light or sound stimuli addresses the limitations of current AD treatments by reducing amyloid plaque deposition and neuroinflammation, enhancing microglial activity, and improving cognitive function.

AI Technical Summary
Current treatments for Alzheimer's disease (AD) are palliative and lack effectiveness in inhibiting pathological progression, with existing medications having toxic side effects and limited cognitive benefits, and there is a need for methods to prevent, mitigate, or treat dementia by addressing the accumulation of amyloid plaques and neuronal loss.
Inducing synchronized gamma oscillations in specific brain regions, such as the hippocampus and sensory cortex, using devices that emit stimuli like light or sound to activate fast-spiking-parvalbumin interneurons, thereby reducing amyloid peptide levels and promoting neuroprotective microglial activity.
The synchronized gamma oscillations reduce amyloid plaque deposition, neuroinflammation, and cognitive decline by decreasing amyloid peptide production and enhancing microglial uptake, improving cognitive function and overall brain health.
