It is now generally recognized that Epilepsy takes many more forms than the commonly known grand mal, falling down types of seizures. There are other forms, far more common: Petit mal, also called absence seizures, that might be characterized by staring off into space, or being unresponsive. Partial complex seizures that may resenble grand mal, but have fewer or less totally involving features. Temporal lobe epilepsy, which some clinicians thing resembles schizophrenia, paranoia, or psychosis, in that it may be accompanied by delusions or hallucinations. There are also silent seizures that may be difficult to detect even for the person having them. In addition, outbreaks of panic, rage, violence, may have seizure-like features, and frequently accompany “sub-clinical” seizure disorder.
The below are some 21 site QEEG recordings of subjects with seizure disorder, used for instructional purposes:
Sometimes seizures are preceded by “storms” of hi-beta activity also called “pro-dromal seizures.” These can also have seizure-like features themselves.
The qEEG protocol below indicates features in the frontal area (frontal beta spindles that could reflect the possibility of kindling.
The alpha activity is appropriately the strongest at O1 and O2. The small beta spindles run throughout the frontal sites, particularly FP2 and F4.
