2. An apparently goal-directed activity that is not, in fact, under the conscious, voluntary control, of the subject (occurring in epilepsy, catatonia, and fugue states).
This subject includes the performance of acts without conscious will, as, for example, after an attack of epilepsy or a concussion of the brain.
In such conditions, the person may perform acts of which he or she is neither conscious of at the time nor has any memory afterwards.
It is especially liable to occur when people suffering from epilepsy, mental subnormality, or concussion consume alcoholic drinks.
During ambulatory automatisms, epileptic patients walk around and are able to carry out some functions without being clearly conscious of either themselves or their surroundings.
