Epilepsy can be categorized into partial seizures and generalized seizures according to the pathogenesis, in which patients with partial seizures may experience involuntary twitching of some limbs, and patients with generalized seizures may experience loss of consciousness. 1. Partial seizures: patients may experience involuntary twitching of some limbs, such as one eyelid, one corner of the mouth, involuntary twitching of one limb, as well as numbness and pins and needles sensation of one limb, pallor, flushing of the face and the whole body, and sweating, etc. If the patient has complex partial seizures or generalized seizures, the patient may experience loss of consciousness. If the patient has complex partial seizures or partial secondary generalized seizures, he or she may have impaired consciousness. 2. Generalized seizures: In generalized seizures, patients with epilepsy may experience loss of consciousness, persistent contraction of skeletal muscles all over the body, and are prone to tongue biting, as well as increased blood pressure, respiratory arrest, and accelerated heart rate. The clinical manifestations of epilepsy are rich and varied, but they all share the following common characteristics: ictal, transient, repetitive, and stereotyped. It is recommended that patients with epilepsy be admitted to the hospital as soon as possible for examination and standardized treatment under the guidance of a doctor according to the severity of the condition.
