Reversible cerebral vasoconstriction may or may not lead to stroke. In many cases, stroke symptoms occur but are completely reversed later. However, some people may be left with permanent deficits. The event may also cause seizures and death.
Who Is Affected by RCVS?RCVS affects women more often than men, being most common after having given birth.
What Causes RCVS?The cause of RCVS is not known, but it is thought that it results from a transient disturbance of the arterial wall, which leads to its constriction. Several substances have been associated with RCVS, including:
- Selective serotonin reuptake inhibitors (SSRIs)
- Nasal decongestants containing pseudoephedrine or ephedrine
- Nicotime patches
