Clinically, there are many symptoms of petit mal seizures, and the presentation will vary in almost every patient. Clinically, the presentation of this disorder varies depending on the type of seizure. Typical petit mal seizure symptoms manifest as a brief loss of consciousness that occurs frequently and lasts about 10 seconds. (1) Loss of consciousness (typical petit mal seizure) This symptom is a brief loss of consciousness, sudden suspension of the original activity, interruption of conversation, pale face, double gaze, indifference, dropping the object in hand, head tilting forward, eyelid fluttering at the corners of the mouth, and sometimes eye fluttering, neither falling nor convulsing. The seizure does not exceed 30 seconds and suddenly stops and resumes. The general intelligence is not affected. If the seizures are frequent, tens or even hundreds of times a day, they may affect learning, and are more frequent at the age of 5-10 years. Patients with grand mal seizures have a reduced degree of medication and only a brief period of unconsciousness, which should still be considered as grand mal seizures, not aphasic seizures. (2) Variable petit mal seizures (atypical petit mal seizures) ① myoclonic seizures: this symptom shows bilateral rhythmic myoclonic jerks mainly in the head and upper limb muscles, which can be single or repeated multiple times, the seizures are not accompanied by impaired consciousness and can occur at any time. (2) Ankinetic seizure: This symptom shows sudden onset of transient loss of muscle tone, thus unable to maintain posture. When standing, it shows sudden head bowing, knee bending and falling. Sometimes it can occur several times in a row with brief loss of consciousness or impaired consciousness immediately. (3) Tonic seizure: This symptom is manifested in sudden tonic contraction of certain muscles, such as trunk forward flexion, head forward tilt, etc. fixed in one posture, lasting for a period of time, usually not more than 1 minute, with a brief loss of consciousness, immediately after the attack. (3) Compound seizures 1, aphasia with myoclonus: this symptom shows patients with facial or limb, eye, eyelid, eye upward movement in addition to aphasic seizures, often leading to falls, EEG EEG shows 3 times/sec spine a slow wave or multi-spine slow wave. 2.Aphasia with increased muscle tone: This symptom is manifested as anterior pitch aphasia, posterior tilt aphasia or rotational aphasia. 3.Aphasia with hypotonia: Aphasia with generalized loss of muscle tone and fall. Sometimes the seizure is mild and only the head is nodding downward (nodding-like seizure), and the EEG shows 3 times/second slow wave synchronization. 4.Aphasia with automatism: In addition to aphasia, it shows sucking, chewing, swallowing, dressing, walking or other purposeless movements. 5.Aphasia with vegetative symptoms: There are aphasia, and also such as: increased or decreased breathing, heart rate, nausea, vomiting, abdominal pain, sweating, urinary incontinence, etc. After the discovery of epilepsy, must be actively treated, wish you a speedy recovery.
