Magnetic Field Enhanced Docosahexaenoic Acid Delivery for Acetylcholine Restoration in Alzheimers Disease an In Silico Study

Alzheimer's Disease is characterized by the gradual loss of Acetylcholine, a vital neurotransmitter for cognition and synaptic communication. Docosahexaenoic acid, the main omega 3 fatty acid in brain cells, can increase Acetylcholine and support the transmission of cholinergic signals, but its effectiveness is hindered by poor blood brain barrier permeability and slow diffusion.

This study utilizes a mathematical model to examine how a static magnetic field can improve DHA's movement and Acetylcholine synthesis. DHA's diamagnetic anisotropy allows it to align along the magnetic field, while body cells form linear arrays along the field. This alignment increases DHA's diffusion rate. At a specific point 0.5cm from the magnetic source, the magnetic field improves the time for Acetylcholine to reach a therapeutic level by 83.3%, from 10.55 seconds to 1.76 seconds.

This improvement is consistent across the entire range of 0 to 3.0 cm from the source, with the time saved increasing from 6.71 seconds at the source to 19.21 seconds at 3.0 cm.

The mechanism behind this improvement was analyzed through co-evolution. Within a 2-second period, the magnetic field increases DHA concentration by 7.39 times compared to the initial level. This elevated DHA drives Acetylcholine levels to 133.7% of the required threshold, as opposed to just 18.1% without the magnetic field assistance.

The researchers propose a Brain Computer Interface (BCI)-based closed loop dosing system for potential clinical trials. These findings provide a mathematically solid theoretical foundation for magnetically enhanced DHA therapy as a potential strategy to restore cholinergic function in Alzheimer's Disease.
