Transient Ischaemic Attacks Related to Carotid Stenosis Precipitated by Straining, Bending, and Sneezing
Postgrad Med J 75:145-146, Harrison, M.J.G., 1999
See this aricle in Pubmed

Article Abstract
Three patients are described in whom one or more carotid territory transient ischaemic attacks (TIAs) were preceded by sneezing, straining, or bending over. It is argued that the mechanism involved dislodgment of embolic material from the site of carotid atheroma. This mechanism should be considered as an alternative to paradoxical embolism when TIAs are precipitated by such psychological manoeuvres. Furthermore, TIAs should be added to the list of medical hazards associated with such events.
