Description
Summary:•Acute unilateral lateral medullary infarction (ULMI) may cause unilateral damage to the respiratory network.•Breathing patterns in ULMI have not yet been systematically analyzed.•ULMI seems to induce or exacerbate irregular breathing patterns, such as ataxic, periodic breathing and shallow tachypnea. Our aim was to perform an exploratory study of various irregular breathing patterns (IBPs) across different sleep stages in patients with acute unilateral lateral medullary infarction (ULMI) and compare them to apparently healthy individuals. Polysomnography (PSG) was analyzed for IBPs, such as periodic breathing, ataxic breathing and tachypnea. IBPs were found in 52 % of healthy and 90 % of ULMI subjects (p = 0.001) and occurred in long (≥ 10 min) episodes in 8% of healthy and 68 % of ULMI (p
