Although recently developed disease-modifying therapies target molecular pathology, their clinical benefits remain modest, underscoring the need for interventions that target dysfunctional circuits. Neuromodulatory techniques such as transcranial magnetic stimulation, transcranial electrical stimulation, and deep brain stimulation demonstrate safety and act at network/system levels to engage target sites, yet these techniques are limited by their ability to modulate deep anatomic structures and/or their invasiveness. Focused ultrasound (FUS) offers the distinct capability of modulating cortical and deep subcortical networks noninvasively and with anatomic precision. Preclinical studies demonstrate that FUS neuromodulation can influence mechanosensitive ion channels, synaptic plasticity, neurotrophic signaling, and oscillatory dynamics, with downstream effects on distributed memory networks. Early human investigations similarly suggest that FUS neuromodulation can alter functional connectivity within default mode, frontoparietal, and limbic networks. Together, these findings support a framework in which FUS may help reshape pathological network states that emerge prior to irreversible neurodegeneration. Here, we present a narrative review of evidence across neuromodulation approaches to define principles of circuit engagement in AD and discuss a network-based rationale for ultrasound interventions. As an illustration of this framework, we also report preliminary findings from a phase I pilot study of FUS neuromodulation in amyloid-positive mild cognitive impairment demonstrating safety, tolerability, and measurable modulation of hippocampal connectivity.

Convergent evidence identifies the dorsolateral prefrontal cortex (dlPFC) as a critical site of molecular, cellular, and circuitry alterations in these disorders. The primate dlPFC contains recurrent, excitatory microcircuits in layer III that sustain working memory and top-down control through specialized forms of neurotransmission and intracellular signaling. Specifically, NMDA receptor and cholinergic modulation, as well as tightly regulated calcium-cAMP (cyclic adenosine monophosphate) signaling within dendritic spines, support task-specific firing of layer III pyramidal neurons but may also increase vulnerability to genetic risk, stress, inflammation, and aging. This review integrates findings from human postmortem studies, neuroimaging, and genetics to examine how dlPFC circuitry is altered in these disease states. In schizophrenia, layer III pyramidal neurons exhibit altered synaptic and cytoskeletal signaling, lower dendritic spine density, and compensatory shifts in inhibitory inputs that likely weaken recurrent excitation and network synchrony. In MDD, dysfunction of dlPFC pathways that regulate the subgenual cingulate cortex contributes to impaired top-down control of emotion and motivation. In AD and frontotemporal lobar degeneration, tau pathology and neurodegeneration target association cortices, including layer III dlPFC circuits, contributing to progressive cognitive decline and impaired executive function.
