Jacksonian epilepsy
Last reviewed 01/2018
Jacksonian epilepsy is a partial epileptic seizure that occurs because of a lesion in the primary motor area.
Such a lesion causes jerking and tonic spasms of the contralateral face and limbs.
In Jacksonian epilepsy, movement begins at the angle of the face or thumb and index finger and then progressively spreads to the arm, trunk, and then the leg and foot.
