What Are Brain Shivers
Brain shivers can be described as one of the unusual withdrawal symptoms that a person experiences, after going through a prolonged use of antidepressants. Till date, mainly the antidepressants venlafaxine (Effexor), duloxetine (Cymbalta) and escitalopram (Lexapro) have been associated with brain shivers. Even amongst all these, Effexor is the one regarded as the major culprit. All of these antidepressants affect the levels of serotonin (a neurotransmitter) in the brain. Many of those people, who have stopped using these antidepressants, after an extended period of usage, reported experiencing brain shivers. There are also some people who underwent brain shivers even after missing one dose only.
It is difficult to define the symptoms of brain shivers exactly. Some people describe them as the feeling of someone vomiting inside your brain, while others say that they felt as if an electric shock just passed through them. Then, there are others who felt like a strobe light pulsed inside their head. In majority of the cases, the brain shiver is followed by a brief, but significant, sense of vertigo, nausea, disorientation, lightheadedness, and/or ringing in the ears. It usually occurs when a person suddenly shifts his eyes or moves his head and is known to last for only a few seconds at a time.
Brain shivers, as the very name suggest, have their main symptom limited to the head only. However, in some of the cases, the sensation begins in the head and then radiates downward and outward as well. Though this particular side effect of antidepressants has not been established by the doctors, the phenomenon has been given a clinical terminology - paresthesia (which basically means tingling), electric shock sensations and discontinuation symptoms. It has been reported by people that brain shivers tend to increase in frequency as the withdrawal time from the antidepressant increases.
