Delusions, illusions and hallucinations in epilepsy: 1. Elementary phenomena

Haliucinacijų etiologijos aspektai

“…Vaizdai, matomi vienoje regėjimo lauko pusėje, leidžia spėti, kad traukulinio aktyvumo epicentras yra priešingoje galvos smegenų srityje. Kartais išsivysto ir sudėtingos haliucinacijos, kas rodo regimosios asociacinės žievės, pamatinių smilkininių vingių ir smilkininės-pakaušinės jungties įsitraukimą (24). Regos haliucinacijos vystosi dėl epilepsinio aktyvumo pakaušinėje galvos smegenų skiltyje.…”

“…Tačiau jų pobūdis yra visiškai kitoks nei migrenai būdingos auros. Klausos haliucinacijos yra asocijuotos su Heschl'o vingiu, kur manoma, kad kyla paprastos haliucinacijos, ir viršutiniu smilkininiu vingiu, taip pat ir kitos smilkininės skilties sritys, kur galimai atsiranda sudėtingos haliucinacijos (24)(25)(26).…”

Single Seizure and Cognition: Clinical and Translational Implications

“…Moreover, according to the conventional point of view, localization of epileptic focus in the left hemisphere is associated with verbal memory impairment, whereas right-side localization is linked with nonverbal memory deterioration [7]. In addition, depending on the brain area involved in the propagation of epileptic activity, epilepsy may be accompanied by occurrence of auditory, olfactory, gustatory, somatic and visual hallucinatory phenomena [8]. Cognitive impairment is determined by factors directly associated with the epilepsy-related characteristics (age at onset, disease duration, duration and frequency of seizures, localization of epileptic focus and reasons for its formation, status epilepticus history), as well as antiepileptic therapy used [3,[9][10][11].…”

A Case of Complex Visual Disturbance in a Patient with Major Depressive Disorder Successfully Treated with Buspar

“…1 Although less common than auditory hallucination, the presence of visual perceptual disturbance in patients with mental illness can be distressing. 2 Ascertaining the cause and type of visual perceptual disturbance occurring in symptomatic patients can be difficult to delineate and are often for descriptive purposes.…”

“…2 Ascertaining the cause and type of visual perceptual disturbance occurring in symptomatic patients can be difficult to delineate and are often for descriptive purposes. 1 An uncommon type of illusion is pareidolia which is a "type of complex visual illusion involving ambiguous forms being perceived as meaningful objects". 3 It is a peculiar, natural, function of the human brain that makes an individual to impose patterns on random collections of images or sounds.…”
