Convulsions and epilepsy present in the same way, but convulsions are not always epilepsy. Epilepsy is a chronic brain disorder with recurrent seizures. It manifests itself in motor, sensory, and autonomic dysfunction. Epilepsy is caused by excessive discharges of neurons in the brain and is recurrent and transient in nature. It can be secondary to head trauma, cerebrovascular disease, tumor, neurological degeneration and other brain diseases, and some causes are not clear. It is prevalent in the elderly and children. Convulsions are mainly triggered by brain disorders, systemic diseases or neurological disorders. Convulsions are one of the common symptoms in neurology, mainly involuntary, paroxysmal twitching of skeletal muscles of the limbs, trunk and face, which may cause joint movements. For example, low calcium, low blood sugar, low blood sodium and intracranial infection may cause convulsive seizures. If patients with similar symptoms must go to a regular hospital for examination, according to the clinical manifestations of electroencephalography and other related tests, to clarify the cause and treatment.
