From: White matter alterations in cluster headache identified using PSMD analysis

Comparison of PSMD between patients with cluster headache and healthy controls. The figure illustrates that patients with cluster headaches have significantly higher PSMD values compared to healthy controls (0.273 × 10⁻ 3 mm²/s vs. 0.227 × 10⁻ 3 mm²/s, p = 0.009). The unit of PSMD in the figure is x 10⁻ 3 mm²/s. PSMD peak width of skeletonized mean diffusivity.
