  • Title: Contribution of concurrent Doppler and EEG in differentiating occipital epileptic discharges from migraine.
    Author: Wilder-Smith E, Nirkko AC.
    Journal: Neurology; 1991 Dec; 41(12):2005-7. PubMed ID: 1745366.
    Abstract:
    In a young woman, episodes of visual symptoms were accompanied by simultaneous nonspecific EEG alterations. Concurrent Doppler sonography showed increased blood flow velocity with latency of a few seconds in the posterior cerebral arteries only. This is typical for local autoregulatory hyperperfusion due to increased neuronal activity, thus indicating focal epileptic discharges and excluding migrainous attacks.
