Seizures

 A seizure happens due to abnormal electrical activity within the brain. It may go nearly unnoticed. Or, in some severe cases, it's going to cause unconsciousness and convulsions, when your body shakes uncontrollably.Seizures usually come on suddenly. How long and severe they are can vary. A seizure can happen to you only once, or over and over. If they keep returning , that's epilepsy, or a seizure disorder. Less than one in 10 people that have a seizure get epilepsy. Experts put seizures into two general categories: Generalized Seizures:These involve your entire brain from the beginning . Common subtypes include:Tonic-clonic (grand mal): This is the most common subtype. Your arms and legs get stiff, and you may stop breathing for a bit. Then your limbs will jerk around. Your head will move about, as well.Absence seizures (petit mal): You lose awareness briefly once you have one among these. Children get them more often than adults. Typically, they last only a couple of seconds.Febrile seizures: These are convulsions a toddler may have from a high fever caused by an infection. They can last a few minutes but are usually harmless. Infantile spasms: These usually stop by age 4. The juvenile body gets stiff suddenly and his head goes forward. Many kids who have these get epilepsy later in life.
