BrainsWay vs Nexstim: Deep TMS vs Navigated TMS

BrainsWay and Nexstim are both premium TMS systems that go beyond standard figure-8 coil approaches. BrainsWay uses the H-coil to reach deeper brain structures with a larger stimulation volume. Nexstim adds MRI-based neuronavigation for precise, personalized targeting. Both are more sophisticated than standard systems — deciding between them requires understanding what each is optimized for.

• Availability and insurance considerations

The Core Difference: Depth vs Precision

BrainsWay optimizes for depth. The H-coil reaches subcortical structures — specifically the anterior cingulate — more efficiently than figure-8 coils. This makes it well-suited for OCD, where those deeper regions are key treatment targets. The targeting is anatomical and functional (the H-coil geometry is designed to maximize deep penetration).

Nexstim optimizes for precision. MRI-based neuronavigation creates a personalized 3D brain map for each patient, with real-time coil tracking. The target is placed with millimeter accuracy based on individual anatomy. This matters most for patients with atypical brain structure or when research-level targeting precision is needed.

OCD: BrainsWay’s Specific Edge

BrainsWay holds the only dedicated FDA clearance for OCD in TMS. The clinical trials that earned that clearance used the H-coil deep TMS protocol targeting the anterior cingulate.

Nexstim can treat OCD off-label and its navigation may offer targeting advantages for OCD. But without the specific indication, insurance coverage is less straightforward, and the labeled protocol data is on BrainsWay’s side.

For OCD patients specifically, BrainsWay is the more practical and accessible choice.

When Nexstim May Be Better

Nexstim’s navigation advantage is most meaningful for:

• Patients who didn’t respond to standard TMS or deep TMS
• Patients with brain anatomy altered by surgery, stroke, or congenital variation
• Research protocols requiring precise, reproducible targeting

If you’ve already tried BrainsWay or standard TMS without adequate response, Nexstim’s precision targeting is worth exploring at an academic center.

Availability and Cost

Nexstim has a smaller US footprint than BrainsWay. The system is found primarily in academic medical centers and specialized neuromodulation clinics. Finding a Nexstim provider requires specific searching.

Both are premium systems. Insurance coverage for Nexstim is less well-established than for BrainsWay, which now has multiple commercial indications.

The Bottom Line

For OCD: BrainsWay wins on availability, insurance, and labeled indication.

For complex or refractory cases: Nexstim’s navigation may offer a genuine advantage.

For most patients: Neither is the first choice over standard NeuroStar TMS, which is more accessible and sufficient for typical treatment-resistant depression.
