Benign childhood epilepsy with central temporal spikes (BECT) is the most common type of benign focal epilepsy in children. It accounts for about 15%-25% of epilepsy in school-aged children and has a good prognosis. Genetic factors: About 30% of cases have a family history of epilepsy. About 10% of children have a parental history of seizures during childhood that resolve in adulthood. Most scholars believe that BECT is autosomal dominant with age-dependent episodes. Acquired factors: About 10% of patients with BECT have previous birth injuries, central nervous system infections, cranial trauma, and febrile convulsions. Clinical manifestations] 1. Age of onset: Generally between 2 and 14 years old. 80% of patients aged 5 to 10 years old have seizures. Seizures: Typical seizure type is limited seizure, some seizures can be followed by generalization, and seizures during sleep are more likely to generalize. The common manifestations of seizures are as follows. (1) Oropharyngeal symptoms: characterized by salivation, corner of the mouth twitching, jaw and tongue shaking, teeth grinding, throat vocalization, abnormal oral sensations such as dryness or tingling and lip and tongue stiffness. (2) Language inability: the seizure is unable to speak, the mind is clear, and the language of others around can be understood, sometimes through gestures to communicate. The hint is mainly related to the tonic or clonic mouth and tongue, not related to the language center. (3) Facial muscle clonus: Generally, it is manifested as one side of the clonus, and the corner of the mouth is the most obvious. It can also be manifested as spastic contraction of one side of the corners of the mouth. (4) Limb syndrome: The seizure may involve the limbs and present with motor and sensory symptoms of one hand, forearm, all upper limbs or one upper and lower limb, including clonic jerking, tonic contractions or sensory abnormalities. Individual cases present with typical Jacksonian seizures. Some present with bilateral limb twitching or stiffness, tingling, etc. (5) Others: A few patients have epigastric pain and transient visual abnormalities during seizures. Individuals are combined with typical anhedonic seizures. The seizures of BECT are closely related to sleep. About 3/4 of the seizures occur during sleep, most of them shortly after sleep or before waking up. 13%-20% of patients have only one seizure, which does not recur with or without treatment. 66% of patients have more than 2 seizures, but they are not frequent. Another 20% of patients have very frequent seizures. EEG features] 1. Interictal period: central and temporal area spike waves (or spike waves). Generally high amplitude biphasic spike waves, with the highest amplitude in the central and temporal regions, followed by slow waves. The frequency of discharges does not correlate with the frequency of clinical seizures. This abnormal discharge can be confined to the middle temporal or central region, but may also spread to the periphery. Generally, the higher the wave amplitude, the easier it is to spread. 2. Seizure phase The seizure phase EEG is less frequently reported and is not specific, showing focal seizure discharges. The central temporal region of the hemisphere contralateral to the seizure body is first involved. Typical abnormal discharges show low amplitude fast activity that spreads to the ipsilateral or contralateral cortex within a few seconds. The abnormal discharge of BECT is significantly more in the sleep period than in the waking period, so for those who are clinically suspected of this disease, or whose seizures are closely related to sleep, sleep EEG should be routinely performed to improve the correct diagnosis. Treatment】: BECT has a good prognosis and clinical remission occurs 2-4 years after the onset of the disease. 95% of the patients respond well to carbamazepine and the seizures can be controlled by single drug, oxcarbazepine can also be used. However, when BECT is combined with ESES phenomenon, carbamazepine and oxcarbazepine should be avoided, which may aggravate the attack, and levetiracetam, sodium valproate or topiramate can be chosen.
