Tonic clonic seizures were also known as “grand mal seizures” in the past. During the seizure, the patient suddenly loses consciousness, the whole body muscles continue to contract strongly, the head tilts back, falls to the ground, the eyes roll up, the teeth clench, the limbs stretch or flex, which lasts for several seconds to tens of seconds and then turns into a faster frequency of whole body tremor. The patient then relaxes and enters deep sleep, may be incontinent, wakes up with generalized aches and pains, and cannot recall the seizure process. The sudden loss of consciousness, the ongoing movements and language stop, eyes stare, expression dull, no response to external stimuli, lasts for a few seconds to tens of seconds and then suddenly recover, continue the actions carried out before the seizure, the patient is often unconscious or only feel the brain “blank”. Third, spasmodic seizures Most often seen in small infants, manifested as a brief nodding with limb flexion-like contraction, or limb extension, head tilted back. The seizures often occur in bunches, with the intensity of each spasm gradually increasing, reaching a peak and then gradually decreasing. The mild spasms are only a brief deviation or upward gaze of the eyes, and are very typical of “knife folding”, “bowing”, or “ball hugging” seizures. The number of seizures per day varies from a few to dozens per string. They often appear before going to sleep or soon after waking up, and the child often cries or is agitated between the spasms. Fourth, myoclonic seizures Patients show nodding, head tilting back or bilateral shoulder and arm twitching, resulting in unstable movements or dropping objects, and if it affects the lower limbs, the patient may stand unsteadily or gait unsteadily and fall suddenly. Myoclonus may appear spontaneously or be triggered by certain factors, such as sound, flashing light, physical sensory stimulation, etc. V. Atonic seizures Short-term atonic seizures, also known as fall seizures, are characterized by a sudden decrease or loss of generalized muscle tone, resulting in the patient’s head dropping or falling. A prolonged dystonic seizure, also known as a motor seizure, is characterized by loss of consciousness, general flaccidity, staring or closing of the eyes, and no vocalization or movement. Localized sensory seizures 1. Basic sensory symptoms: monotonous, contentless or shapeless sensory symptoms originating from body sensations, vision, hearing, smell, taste or visceral sensations, often indescribable sensations that have never been experienced in daily life. For example: localized pins and needles, numbness, flashing lights, dark spots, black haze in front of the eyes, hearing beeps, drums, noise or distorted sensations such as external sounds suddenly becoming louder, smaller, farther or closer, smelling unpleasant smells, etc. 2.Complex sensory symptoms: Patients have memory disorders, such as unfamiliarity, déjà vu, panoramic flashbacks of past experiences; perceptual disorders, such as dream-like states, abnormal sensation of time or space; emotional disorders, such as fear, anger, depression, euphoria, etc.; hallucinations or delusions such as a sense of personality dissolution.
