Editing Hallucination (section)

===Focal epilepsy===
Visual hallucinations due to [[focal seizure]]s differ depending on the region of the brain where the seizure occurs. For example, visual hallucinations during [[occipital lobe]] seizures are typically visions of brightly colored, geometric shapes that may move across the [[visual field]], multiply, or form concentric rings and generally persist from a few seconds to a few minutes. They are usually unilateral and localized to one part of the visual field on the contralateral side of the seizure focus, typically the [[Temporal lobe|temporal field]]. However, unilateral visions moving horizontally across the [[visual field]] begin on the contralateral side and move toward the ipsilateral side.<ref name="Panayiotopoulos_2007" /><ref name="Teeple_2009">{{cite journal | vauthors = Teeple RC, Caplan JP, Stern TA | title = Visual hallucinations: differential diagnosis and treatment | journal = Primary Care Companion to the Journal of Clinical Psychiatry | volume = 11 | issue = 1 | pages = 26–32 | year = 2009 | pmid = 19333408 | pmc = 2660156 | doi = 10.4088/PCC.08r00673 }}</ref>

[[Temporal lobe epilepsy|Temporal lobe seizures]], on the other hand, can produce complex visual hallucinations of people, scenes, animals, and more as well as distortions of [[visual perception]]. Complex hallucinations may appear to be real or unreal, may or may not be distorted with respect to size, and may seem disturbing or affable, among other variables. One rare but notable type of hallucination is [[heautoscopy]], a hallucination of a mirror image of one's self. These "other selves" may be perfectly still or performing complex tasks, may be an image of a younger self or the present self, and tend to be briefly present. Complex hallucinations are a relatively uncommon finding in temporal lobe epilepsy patients. Rarely, they may occur during occipital focal seizures or in [[parietal lobe]] seizures.<ref name="Panayiotopoulos_2007" />

Distortions in visual perception during a temporal lobe seizure may include size distortion ([[micropsia]] or [[macropsia]]), distorted perception of movement (where moving objects may appear to be moving very slowly or to be perfectly still), a sense that surfaces such as ceilings and even entire horizons are moving farther away in a fashion similar to the [[Dolly zoom|dolly zoom effect]], and other illusions.<ref>{{cite journal | vauthors = Bien CG, Benninger FO, Urbach H, Schramm J, Kurthen M, Elger CE | title = Localizing value of epileptic visual auras | journal = Brain | volume = 123 ( Pt 2) | issue = 2 | pages = 244–253 | date = February 2000 | pmid = 10648433 | doi = 10.1093/brain/123.2.244 | doi-access = free }}</ref> Even when consciousness is impaired, insight into the hallucination or illusion is typically preserved.<ref>{{Cite journal |last1=Teeple |first1=Ryan C. |last2=Caplan |first2=Jason P. |last3=Stern |first3=Theodore A. |date=2009-02-15 |title=Visual Hallucinations: Differential Diagnosis and Treatment |url=https://www.psychiatrist.com/pcc/visual-hallucinations-differential-diagnosis-treatment |journal=The Primary Care Companion to the Journal of Clinical Psychiatry |volume=11 |issue=1 |pages=26–32 |doi=10.4088/PCC.08r00673 |pmid=19333408 |pmc=2660156 |issn=1523-5998}}</ref>
