Dual nerve block technique shows promise for stubborn anxiety cases

A research team in Karnataka has reported that a dual nerve block approach may offer relief to individuals with anxiety that has not improved after conventional therapy, according to The Hindu. The study evaluated patients who received two sequential nerve block injections and tracked changes in anxiety severity over several weeks.

The investigators observed that participants experienced a measurable reduction in anxiety symptoms following the combined procedure, with many noting improved daily functioning. While the report did not disclose exact percentages or sample sizes, it highlighted the potential of this minimally invasive method as an adjunct to medication and psychotherapy.

Anxiety disorders affect millions worldwide and are a leading cause of disability. Standard care typically involves cognitive‑behavioral therapy, antidepressants, or anxiolytics. However, a subset of patients—often termed "treatment‑resistant"—fails to achieve adequate control, prompting clinicians to explore alternative interventions such as neuromodulation, transcranial magnetic stimulation, and nerve blocks.

Nerve block techniques involve injecting anesthetic agents near specific peripheral nerves to interrupt pain or stress pathways. The dual approach described in the Karnataka study likely targets two distinct neural circuits implicated in the stress response, though the article did not specify which nerves were involved. Prior research on single nerve blocks, such as the stellate ganglion block, has shown short‑term anxiety relief, suggesting that a combined strategy could amplify benefits.

If larger trials confirm these early findings, the dual nerve block could become a valuable tool for psychiatrists and pain specialists dealing with refractory anxiety. The procedure’s relative simplicity and outpatient setting may make it accessible in tertiary care centers across India, potentially reducing the burden on mental‑health services.

The study’s authors caution that more rigorous, randomized trials are needed to establish safety, optimal dosing, and long‑term outcomes. Nonetheless, the initial results add to a growing body of evidence that targeting the nervous system directly can complement traditional psychiatric care.

The Hindu reported the findings, underscoring the importance of interdisciplinary research in addressing complex mental‑health challenges.
