The lateral femoral cutaneous nerve (L2, L3) leaves psoas major laterally below the previous nerve, runs obliquely and laterally downward above the iliacus, exits the pelvic area near the iliac spine, and supplies the skin of the anterior thigh.The obturator nerve (L2-L4) passes medially behind psoas major to exit the pelvis through the obturator canal, after which it gives off branches to obturator externus and divides into two branches passing behind and in front of adductor brevis to supply motor innervation to all the other adductor muscles. The anterior branch also supplies sensory nerves to the skin on a small area on the distal medial aspect of the thigh. The femoral nerve (L2-L4) is the largest and longest of the nerves of the lumbar plexus. It supplies motor innervation to iliopsoas, pectineus, sartorius, and quadriceps; and sensory branches to the anterior thigh, medial lower leg, and posterior foot.The nerves of the sacral plexus pass behind the hip joint to innervate the posterior part of the thigh, most of the lower leg, and the foot. The superior (L4-S1) and inferior gluteal nerves (L5-S2) innervate the gluteus muscles and the tensor fasciae latae. The posterior femoral cutaneous nerve (S1-S3) contributes sensory branches to the skin on the posterior thigh. The sciatic nerve (L4-S3), the largest and longest nerve in the human body, leaves the pelvis through the greater sciatic foramen.
Sleep-related hypermotor epilepsy (SHE), previously known as nocturnal frontal lobe epilepsy, is a form of focal epilepsy characterized by seizures which arise during sleep. The seizures are most typically characterized by complex motor behaviors. It is a relatively uncommon form of epilepsy that constitutes approximately 9-13% of cases. This disorder is associated with cognitive impairment in at least half of patients as well as excessive daytime sleepiness due to poor sleep quality. This disorder is sometimes misdiagnosed as a non-epileptic sleep disorder. There are many potential causes of SHE including genetic, acquired injuries and structural abnormalities. History
In 1981, Lugaresi and Cirignotta described a group of 5 patients with paroxysmal attacks of violent movements of the extremities and dystonic-tonic posturing. It was initially uncertain whether these events constituted seizures or something else. However, the patients had a good clinical response to the anti-seizure medication carbamazepine. Ultimately, the epileptic nature of this condition was confirmed with EEG and suggested that they were coming from the frontal lobe. The term “nocturnal frontal lobe epilepsy” was suggested as a name for this condition. Later in 2014, a consensus conference recommended that the name be changed to sleep-related hypermotor epilepsy. There were three main justifications for this change: (1) not all seizures arise from the frontal lobe; (2) seizures do not necessarily occur during the night but rather from sleep; (3) hypermotor describes the most common visible clinical manifestation of the seizures. Symptoms
Seizures in SHE are brief and usually have an abrupt onset and offset.
