Epileptic waves during a seizure on an EEG Procedures for diagnosis of<unk>  include hematology, biochemistry, screenings for metabolic disorders, DNA analysis, and most commonly, MRI. Electroencephalogram (EEG) is also used to detect abnormal brain waves and activity that is reflected as slow waves, or spikes on the recordings. For<unk> , commonly identified abnormalities on the EEG when a seizure is not occurring (inter-ictal) includes posterior lateralized slow waves, asymmetrical alpha and photic following, and unilateral<unk>  spikes. Idiopathic cases may appear mostly normal, with<unk>  spikes or paroxysms. Ictal EEG’s show<unk>  paroxysmal fast activity, spiking, or both, as well as brief<unk>  flattening. About one-third of<unk>  seizures do not show any obvious changes. An MRI would be performed to look at any lesions, damage, or abnormalities in the<unk>  region of a patient’s brain. More specifically, a functional MRI, or fMRI, can detect changes in blood flow throughout the brain when specific parts of the brain are being used. Blood tests and other hematological assays can check for any signs of infection, genetic conditions, or other conditions that could be causing seizures. Computerized tomography (CT) can also be used to detect any abnormalities such as tumors, lesions, bleeding, or cysts. Based on all of these techniques, a provider would conclude if it appears that there has been seizure activity in a patient’s brain, where it is located, and the severity of the condition, based on any existing tissue damage.
