Description
Marta Reales-Moreno's team reviewed fractal analysis as a way to characterise brain patterns in mental illness, in a 2026 systematic review. Mental-health diagnosis rests on symptoms and classifications, while brain scans hold complex organisation that standard tests may miss. Fractal dimension, a number capturing pattern complexity, promises a complementary lens. The team reviewed 39 original studies of brain-shape and brain-activity scans.
Schizophrenia and autism dominated the literature, and frontal-cortex abnormalities recurred across conditions. Whole-brain tests, however, may have diluted local effects by averaging too much tissue. The authors conclude fractal analysis reveals shared shape and activity patterns, but without a standard protocol its clinical use for earlier or sharper calls remains out of reach.
