Symptoms of seizures depend on the seizure type and the part of the brain it starts in. Some symptoms of focal seizure include muscle jerking or twitching on one side of the body, repetitive movements such as chewing or blinking, and periods of staring. Some people with focal seizures also experience smelling strange smells and changes in their vision. Focal seizures may be preceded by an 'aura', a collection of distinctive sensations before a seizure occurs. Symptoms of generalized seizures include stiffening of the muscles, muscle jerking, loss of consciousness and staring episodes. Some people with generalized symptoms may bite their lip or tongue while having a seizure and lose control of their bladder and/or bowels.
