Focal seizures occur when this electrical activity is in a limited area of the brain. Sometimes the seizures stay only in one part of the brain, while at other times, the seizures can turn into bilateral tonic-clonic seizures, which affect the whole brain. This is called secondary generalization.Bilateral tonic-clonic seizuresBilateral tonic-clonic seizure is a type of seizure that involves the entire body. It is also called grand mal seizure. The terms generalized seizu...ImageRead Article Now Book Mark Article Focal seizures can be divided into whether they affect awareness or not:Focal, aware Focal, awareness impairedFocal seizures are also classified by whether they are motor (movements with the seizures) or not. Causes Focal seizures are the most common type of seizure in people 1 year and older. In people older than 65 who have blood vessel disease of the brain or brain tumors, focal seizures are very common. Focal seizures are usually associated with an area of the brain in which nerve cells are easily excitable. This is often due to brain injury that can result from conditions such as stroke, infection, trauma, or from problems present at birth. Symptoms People with focal, awareness impaired seizures may or may not remember any or all of the symptoms or events during the seizure.Depending on where in the brain the seizure starts, symptoms may include:Abnormal muscle contraction, such as abnormal head or limb movements Muscle contractionMuscle cramps are when a muscle gets tight (contracts) without you trying to tighten it, and it does not relax.
