The pathophysiological processes underlying onset and progression of amyotrophic lateral sclerosis (ALS) remain poorly understood. Unlike conventional imaging techniques, which provide information only at a gross structural level, advanced imaging modalities have shed light on the microstructural changes that accompany this disease. Eva Feldman and colleagues describe how advanced neuroimaging studies have delineated key factors, such as white matter tract integrity and brain metabolism, that are altered in ALS, and consider how such insights could aid diagnosis and treatment.
