Brain Connectome for Acupuncture-treated Migraine Patients

Since 2002, acupuncture has been employed as a method for treating headaches and migraine. It is recognized by the World Health Organisation (WHO), and is now part of the prophylactic treatments for migraine. Brain activations/de-activation via acupuncture lead to a modification of haemodynamic responses in the brain which may impact the sensorial, cognitive and affective dimensions of pain. Randomized studies on patients who suffer from migraine without aura have shown that the painkilling effect of repeated acupuncture sessions on the cerebral substratum, compared with simulated sham-type acupuncture, make it possible to reduce the frequency of bouts of migraine, the number of days of headaches, and the intensity of the bouts. Following repeated sessions of acupuncture treatment for pain, modifications occur in the white matter (WM) and in the grey matter (GM) and these may be observed by magnetic resonance imaging (MRI) which is a highly sensitive technique and very often used to detect functional brain changes and/or subtle abnormalities.
