Negative seizures.
Negative phenomena can occur with seizures, but some ictal negative manifestations are rare and may lead to misdiagnosis. A patient series is presented with unusual ictal negative phenomena: neglect syndrome, catastrophic depression, apraxia, aphasia, amnesia, homonomous hemianopsia, and hemiparesis. One had repeated episodes with PLEDs but no parenchymal lesions. Clinicians should consider seizures in the setting of unexplained deficits, even if there are no positive ictal phenomena.
