epilepsy, tonic-clonic (medicine)


epilepsy, tonic-clonic
Primary generalised epileptic seizures, starting without warning, characterised by loss of consciousness, tonic contraction of muscles, loss of postural control, and production of a cry by the forced expiration of air due to contraction of the respiratory muscles. The individual then falls to the floor and remains rigid for a few seconds, after which a series of rhythmic contractions occur in all four limbs. This clonic phase can last for a variable period, ending only upon muscle relaxation. Upon recovery, there is a gradual return to consciousness, disorientation, amnesia for the seizure, sometimes retrograde amnesia as well, headache, and drowsiness. The individual may not return to baseline functioning for days.
