Neurologista, desmaio


OFainting (syncope)it is the rapid and sudden loss of consciousness, usually accompanied by loss of strength in the muscles.  In most cases, it tends to be rapid, with a return to consciousness after a few seconds or a few minutes. But as it can often lead to falls and, consequently, trauma, it should always be investigated and, if possible, treated.

They can be the cause of fainting, brain diseases such asEpilepsy, or heart disease likearrhythmias,postural hypotension, and many others.

Stressful situations and strong emotions, closed or hot environments, use of some medications, can also predispose to fainting or the feeling of pre-fainting (or almost fainting), calledlipothymia.
