Seizures

A seizure is a sudden attack affecting physical or behavioral action and is caused by abnormal electrical activity in the brain. Seizures can result in uncontrolled bodily, sensational, awareness, or emotional changes lasting from seconds to minutes. Recurring seizures may be due to epilepsy. There are more than 32 different types of seizures due to the complexity of brain function, yet most seizures can be classified into two major categories: partial seizures and generalized seizures. Although most causes of seizures are unknown, some recognized causes include brain diseases such as meningitis or hydrocephalus, head trauma, stroke, infection, or brain tumors, brain poisoning caused by exposure to carbon dioxide and lead or poor nutrition and lack of sufficient oxygen in babies can induce seizures. High fever in children may cause seizures, known as febrile convulsions. The occurrence of seizures tends to be genetically inherited. Seizures may be chemically influenced due to the abuse of some substances, such as cocaine, or the overdose of antidepressants.
