Diagnosis
The condition may be difficult to diagnose. The subject himself/herself may be unaware s/he is having a seizure disorder. To others, the involuntary movements made during sleep may appear no different than those typical to normal sleep.
One who suffers a nocturnal seizure may notice some unusual differences upon awakening in the morning, such as a headache, having wet his/her bed, having bitten his/her tongue, a bone or joint injury, or lightheadedness. Others may notice unusual mental behaviors with the person, consistent with the aftermath of a seizure. There may also be objects in the vicinity of the bed knocked on the floor, or the subject him/herself may be surprised to find him/herself on the floor.
A possible risk of any nocturnal seizure is that a concussion, possibly a significant one, could occur and the patient thus would be in danger and might not know it until late in the process.
