A convulsion is a medical condition where the body muscles contract and relax rapidly and repeatedly, resulting in uncontrolled shaking.
[3] A person having a convulsion may experience several different symptoms,[1] such as a brief blackout, confusion, drooling, loss of bowel or bladder control, sudden shaking of the entire body, uncontrollable muscle spasms, or temporary cessation of breathing.
[5] In these patients, the frequency of occurrence should not downplay their significance, as a worsening seizure state may reflect the damage caused by successive attacks.
[5] Symptoms may include:[verification needed] Most convulsions are the result of abnormal electrical activity in the brain.
Other possibilities include celiac disease,[7] head trauma, stroke, or lack of oxygen to the brain.
[8] It is a noncontagious illness and is usually associated with sudden attacks[9] of seizures, which are an immediate and initial anomaly in the electrical activity of the brain that disrupts part or all of the body.
[further explanation needed][8] Epileptic seizures can have long-lasting effects on cerebral blood flow.
During this, the patient may fall and injure themselves or bite their tongue, may lose control of their bladder, and their eyes may roll back.
[15] GTCSs are very hazardous, and they increase the risk of injuries and sudden unexpected death in epilepsy (SUDEP).
[19] The exact reason for febrile convulsion is unidentified, though it might be the outcome of the interchange between environmental and genetic factors.
[22] A few neuroimaging (functional and structural) studies suggest that PNES may replicate sensorimotor alterations, emotional regulation, cognitive control, and integration of neural circuits.
