Complex visual hallucinations and occipital seizures
Abstract:Walterfang M, Yerra R, Gaillard F, O’Brien T, Mocellin R, Velakoulis D. Complex visual hallucinations and occipital seizures. Background:
We describe the presentation of a young woman with long-standing complex partial seizures with occasional secondary generalization, who presented with complex visual hallucinations (CVHs) and delusions. Methods:
Routine biological workup including magnetic resonance imaging revealed an area of significant left-sided occipital gliosis. Video telemetry monitoring revealed a left occipital focus for the origin of the electrographic seizure discharge. Conclusion:
CVHs occur in a range of organic states, including epilepsy, and can be understood in terms of the underpinning neuroanatomy and neurotransmitter systems of the visual system.
