Scientists are currently working to reduce the emotional charge related to a painful memory. It seems that migraine can fulfill this role.
Mitigate its traumatic memories through a drug? This promise may sound totally crazy, and yet it seems that the laboratory of traumatic stress from Toulouse, attached to the University Paul Sabatier and the University Hospital, developed this innovative treatment.
The effects on the brain propranolol
This breakthrough, described by La Dépêche du Midi, is made possible with the propranolol, a migraine drug class of beta blockers.
La Dépêche du Midi recalls that the effects of propranolol were discovered in the 1990s when tested on laboratory mice. After unpleasant sensations, rodents who received drug injection off again explore the cage. The others continued to hide in a corner.
In the 2000s, the Canadian Professor Alain Brunet has tested this process in people with chronic post-traumatic symptoms in response to aggression or an accident.
Subsequently, the drug has also been tested on people traumatized by the September 2001 explosion of the AZF plant. Eight people have been treated with propranolol and twenty-five others preferred to be followed without treatment for six months.
"Among the eight patients, there was the decrease symptoms of post-traumatic stress: sweating, sleep disturbances, exaggerated bursts ..." explains Professor Philippe Birmes, who works with the CRCA and quoted by the newspaper. "We are in the research phase but believes many it is a hope for many patients: the drug is cheap, generic, and the effects are there in six sessions. "
Administered 90 minutes prior to the reactivation of a traumatic memory, propranolol may reduce the emotional charge related to a painful memory. After taking the patient had to write a text in the first person in which he told her trauma. This experiment was repeated in six session. Each time, the levels of post-traumatic stress symptoms were measured.
Prof. Birmes emphasizes that memories do not disappear. He hopes that eventually it will be possible for the patient to take this medicine at home.
