![]() Medical History: If you have started to have seizures after experiencing severe head trauma or after being diagnosed with a brain tumor, there is a strong chance that they are focal seizures.A generalized seizure is not typically associated with such a correlation between brain imaging and seizure symptoms or EEG patterns. A focal seizure may be associated with abnormalities on brain imaging tests that correspond to the initial seizure symptoms or the EEG pattern.A person who has focal seizures may have erratic electrical activity in one specific area on electroencephalogram (EEG) testing, while a person with generalized seizures is expected to have a more widespread pattern of irregularity. ![]() A focal seizure can produce residual symptoms of weakness such as Todd’s paralysis after the seizure is over, while a generalized seizure typically does not.A generalized seizure manifests with generalized symptoms, such as loss of consciousness or whole-body convulsions from the start. A focal seizure may begin with symptoms such as spasms or muscle tightness on one side of the face, arm, or leg before the symptoms begin to involve changes in consciousness or more widespread involuntary movements. ![]()
