The Info List - Convulsions


--- Advertisement ---



A convulsion is a medical condition where body muscles contract and relax rapidly and repeatedly, resulting in an uncontrolled shaking of the body.[1] Because epileptic seizure is often a cause of convulsion, the term convulsion is sometimes used as a synonym for seizure. However, not all epileptic seizures lead to convulsions, and not all convulsions are caused by epileptic seizures. Convulsions are also consistent with an electric shock and improper enriched air scuba diving. For non-epileptic convulsions, see non-epileptic seizures. The word "fit" is sometimes used to mean a convulsion or epileptic seizure.[2]

Signs and symptoms[edit] When a person is having a convulsion, they may experience several different symptoms. These may include: a brief blackout, confusion, drooling, loss of bowel/bladder control, sudden shaking of entire body, uncontrollable muscle spasms, temporary cessation of breathing, and many more. Symptoms usually last from a few seconds to around 15 minutes. If someone has a fit like this, it is advised to make sure they don't fall and injure themselves, cushion their head and loosen any restricting clothing/jewelry, and also call for medical help. Do not try to pin/hold them in place, as this could possibly cause harm or injury to the individual. Do not place anything between the person's teeth during a seizure (including your fingers).[1] Generalized seizures[edit] Main article: Tonic-clonic seizures The most common type of seizure is called a generalized seizure, also known as a generalized convulsion. This is characterized by a loss of consciousness which may lead to the person collapsing. The body stiffens for about a minute and then jerks uncontrollably for the next minute. During this, the patient may fall and injure themselves or bite their tongue and lose control of their bladder. A familial history of this puts a person at a greater risk for developing them.[3][4] Causes[edit] Convulsions are often caused by some sort of electrical activity mishap in the brain. Oftentimes, the cause cannot be pinpointed. Convulsions can be caused by chemicals in the blood, as well as infections like meningitis or encephalitis. A very common cause of convulsions is fevers. Other possibilities include head trauma, stroke or lack of oxygen to the brain. Sometimes the convulsion can be caused by genetic defects or brain tumors.[1] Convulsions can also be caused by any type-1 diabetic, whose blood sugar is too low. Hypoglycemia can cause very bad convulsions until the person's blood sugar is raised to normal level. Convulsions can also be caused by deficiency of vitamin B6 (pyridoxine). References[edit]
