Ictal visual hallucinations due to frontal lobe epilepsy in a patient with bipolar disorder.

Manfioli V, Saladini M, Cagnin A - Epilepsy Behav Case Rep (2013)

Bottom Line: In ictal psychosis with complex visual hallucinations (VHs), widespread functional changes of cortical networks have been suggested.We describe the clinical and EEG findings of a patient with bipolar disorder who manifested complex VHs associated with intense emotional symptoms caused by frontal epileptic seizures.This description highlights the challenges of diagnosing the epileptic nature of new psychotic phenomena in patients with previous psychiatric disorders and shines light into the role of the frontal cortex in the genesis of complex VHs.

ABSTRACT
In ictal psychosis with complex visual hallucinations (VHs), widespread functional changes of cortical networks have been suggested. We describe the clinical and EEG findings of a patient with bipolar disorder who manifested complex VHs associated with intense emotional symptoms caused by frontal epileptic seizures. This description highlights the challenges of diagnosing the epileptic nature of new psychotic phenomena in patients with previous psychiatric disorders and shines light into the role of the frontal cortex in the genesis of complex VHs.

f0015: Interictal EEG characterized by normal rhythms with preservation of voltage suppression with eye opening. Sensitivity: 7 μV/mm; TC: 0.1 s; HF: 50.0 Hz.

Mentions: During EEG recording, he experienced the same complex VH as described above. Ictal EEG showed the sudden appearance of continuous rhythmic spikes at a frequency of 5 Hz/s localized on the frontal regions bilaterally and lasting 40 s, followed by spikes and spike–waves in the same regions, lasting 9 min (Fig. 1), and abruptly discontinued with transient postictal slowing of rhythms (Fig. 2). Afterward, a return of normal EEG activity was maintained in the interictal phases (Fig. 3). Cerebrospinal fluid investigations excluded infective encephalitis. Brain magnetic resonance imaging showed the presence of mild cortical atrophy mainly in the frontal regions.
