Clinical and neuroimaging features in MELAS cohort and healthy study controls.

Key: FVC = forced expiratory vital capacity is the volume change of the lung between a full inspiration to total lung capacity and a maximal expiration to residual volume; FEV1 = forced expiratory volume is the volume exhaled during the first second of a forced expiratory maneuver started from the level of total lung capacity; MOCA = Montreal Cognitive Assessment which is a cognitive screening test—a score of ≥ 26 is considered normal; N/A = not done due to difficulty with cooperation; SLEs = stroke-like episodes.
