Neuromodulation techniques targeting neurotransmitter dysfunction: Innovation in treatments for Alzheimer's disease

Area of Science:

• Neuroscience
• Neurology
• Biomedical Engineering

Background:

• Alzheimer's disease (AD) involves progressive cognitive decline, synaptic dysfunction, and neurotransmitter imbalance.
• Neuromodulation offers potential therapeutic strategies for AD by restoring neural integrity and cognitive function.
• Understanding the interplay between neuromodulation, neural circuits, and neurotransmitters is crucial for developing effective AD interventions.

Purpose of the Study:

• To review and synthesize recent advances in neuromodulation techniques for Alzheimer's disease.
• To elucidate the relationship between neuromodulation, neural network circuits, and neurotransmitter systems.
• To propose a novel "circuit-transmitter" triad framework for AD intervention.

Main Methods:

• Systematic review of current neuromodulation techniques.
• Focus on modulation of cholinergic, glutamatergic, GABAergic, and monoaminergic systems.
• Evaluation of clinical viability and synaptic plasticity mechanisms.

Main Results:

• Neuromodulation effectively targets key neurotransmitter systems implicated in AD.
• A strong association exists between neurotransmitter regulation, synaptic plasticity, and cognitive function.
• The hippocampus-thalamus axis is identified as a promising target for ultrasonic neuromodulation.

Conclusions:

• Neuromodulation presents a viable therapeutic avenue for Alzheimer's disease.
• The proposed "circuit-transmitter" framework offers a novel approach to AD intervention.
• Targeting the hippocampus-thalamus axis warrants further investigation for ultrasonic neuromodulation in AD.
