Cardiovascular autonomic dysfunction (CVAD) is a malfunction of the autonomic control of circulatory homeostasis and is an important component of post-COVID-19 syndrome. In this Review, Fedorowski and colleagues define the major forms of CVAD (including postural orthostatic tachycardia syndrome), and discuss the aetiology, diagnosis and management of post-COVID-19 syndrome-associated CVAD.

Acute depletion of meningeal lymphatic vessels impairs the clearance of cerebrospinal fluid and brain macromolecules. A new study by Antila et al. shows that amyloid pathology in Alzheimer’s disease is neither improved nor aggravated by genetic expansion or depletion of meningeal lymphatic vessels.

The link between migraine and cardiovascular disease is complex and involves overlapping mechanisms, such as endovascular disturbances. Challenges in measuring migraine, in distinguishing between causation and prediction, and in the understanding of clinical implications highlight the need for further research to guide treatment and cardiovascular risk assessment for the millions of individuals living with migraine.

The post-acute sequelae of COVID-19 present major problems for many patients, their physicians and the health-care system. They are unrelated to the severity of the initial infection, are often highly symptomatic and can occur after vaccination. Many sequelae involve cardiovascular autonomic dysfunction, with postural orthostatic tachycardia syndrome in 30% of individuals. Prognosis is unknown, and treatment is still unsatisfactory.
