Answer

Answer

Severe but reversible diffuse abnormalities can occur and are exemplified by the so-called low-voltage pattern throughout the EEG record. QS and AS are only distinguishable by the slightly higher voltage in QS, where mixed frequencies under 10–50 mV are almost continuously recorded. This finding and a diffuse delta pattern with minimal theta rhythms throughout the entire EEG record hold an intermediate prognosis. When the abnormalities are compatible with these changes seen in sleep, they are generally considered moderate and reversible.
