They are called developmental. Some synesthesias may be, on the contrary, acquired following a brain injury or in certain diseases, such as Parkinson’s disease, damage of the optic nerve or temporal lobe epilepsy. The synesthesias may just be intermittent. Migraines are sometimes accompanied by phenomena synesthetic that disappear when the crisis ends. Similarly, the taking of certain drugs, in particular LSD and mescaline, often causes associations synesthetic disappear when the “trip” ends.
