The focal attenuation pattern refers to a single scalp region with a persistent voltage attenuation. This pattern has an inconsistent association with neuropathological lesions; both false-positive and false-negative correlations have been observed. Focal slowing is highly unusual and may be a sign of ongoing seizures.
