The precursors of seizures in children include prodromal and aura symptoms in two situations, as follows: 1. Prodromal symptoms: generalized discomfort, irritability, irritability, depression, fussy or whining may occur in the days or hours before a grand mal seizure, i.e., a generalized tonic-clonic seizure. When a child has these symptoms, it is a sign that the child may have a grand mal seizure in a few hours or days. Parents should provide good psychological care, help stabilize the child’s mood, and contact the child’s doctor to get relevant guidance. If necessary, the dose of antiepileptic drugs taken by the child can be increased or other antiepileptic drugs can be added under the guidance of the doctor to prevent seizures; 2. Aura symptoms: that is, the child has delusions, hallucinations, automaticity, local muscle clonus or other special sensations, etc. When the child has such symptoms, parents should prepare the child before the grand mal seizure, such as having the child immediately lie down in bed or on the ground, or take the child quickly away from dangerous areas such as roads, stoves, swimming pools and river banks. In addition, remove hard objects from the child’s side or place dental pads between the child’s upper and lower teeth to avoid damage to the child during a seizure.
