What Are Petit Mal Seizures?
In contrast to major seizures, it includes various seizures that have a smaller range and persist for a shorter period of time. Today, the term microseizure is still used for many types of epileptic seizures, such as microrotational seizures, forward microseizures, and so on. However, most people use the term epileptic seizures based on the characteristics of the EEG, specifically for the absence of seizures, myoclonic seizures, and epileptic fall episodes. Some people also use it for atypical absence. Seizures can be primary or secondary and are more common in children and adolescents.

Causes of epilepsy and common diseases
- Most scholars believe that thalamic and caudate nucleus suppression systems are seen in patients with microseizures, so when the first discharge from the mesencephalic convulsions is emitted to the cerebral cortex, the thalamic and caudate nucleus suppression system will work, only clinically Disorders of consciousness, myoclonus or muscle tension disappeared without convulsive EEG. It is characterized by a combination of high-amplitude bilateral symmetrical spines and slow waves three times per second, in which spikes represent thalamus discharge (excitation process) and slow waves are emitted by thalamus and caudate nucleus (inhibition process) to suppress systemic convulsions. Myoclonic microseizures are not easy to find the focal point of EEG because clinical seizures often occur on both sides, and are generally considered to be a type of central brain systemic seizures. The EEG of a small episode with a large episode is bilateral bilateral 3 weeks / second spike slow wave. After several seconds, the spike component gradually disappears to a high amplitude rhythmic sine wave of 6 to 10 weeks per second. Sexual tonic convulsions, however, are accompanied by loss of consciousness at 3 weeks of slow spikes per second.
Differential diagnosis of epilepsy
- All patients met the relevant diagnostic criteria in "Epilepsy", showing a sudden and brief loss of consciousness, activity stopped, and recovery in seconds or tens of seconds; at the same time or accompanied by small tremors in the hands, lips and head, loss of tension, The symptoms such as loss of holding objects and sudden fall while walking; all patients had undergone EEG examination, showing abnormalities to varying degrees.
Seizure check
- In a typical minor episode, the patient presents with a sudden cessation of his daily activities, his body remains still, his eyes are fixed, his face is dull, but the child does not fall or twitch. Minor episodes usually last 10 to 15 seconds, and then continue his activities. Some children have small episodes that occur multiple times a day. Minor seizure EEG is characterized by a "spike" discharge 3 times per second.
Epilepsy treatment principles
- Nowadays, western medicine is mainly used for valproic acid and nitroazepam, and some patients or their families choose traditional Chinese medicine for fear of the side effects of taking western medicine for a long time.
