Phenomenology of hallucinations, illusions, and delusions as part of seizure semiology

Autistic characteristics in adults with epilepsy

“…In addition, neuroimaging has implicated the somatosensory cortex in the formation of somatic markers . Consistent with this, somatosensory impairments are common to TLE, and part of seizure semiology (Kasper et al, 2010). Therefore, it can be inferred from Experiment 7 that vmPFC functioning differences are implicated in disrupting the regulation of typical somatic marker formation in adults with epilepsy.…”

“…Seizure auras are a stage of epilepsy which occur without loss of full consciousness, but awareness is lost as the seizure spreads to involve both temporal lobes (Nakken, Solaas, & Kjeldsen, 2009). Seizure auras present with sensory or autonomic symptoms such as somatosensory and sensory phenomena, disturbing all five senses (Kasper, Kasper, Pauli, & Stefan, 2010). Such phenomena can sometimes be referred to as hallucinations, which are defined as a sensory perception in the absence of adequate external stimulus (ibid., p.14).…”

Haliucinacijų etiologijos aspektai

“…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).…”

Diagnostic challenge in neuropsychiatry: two case reports

“…Though such experiences have long been known to be inducible by psychotropic agents, to occur during spiritual exercises, and to exist in association with various diseases. In addition, knowledge of the hallucinatory symptoms of epilepsy and their relationship to neuro-physiological cerebral processes has taken a long time to emerge [1]. This knowledge has developed in line with the increasing knowledge about the brain itself, ranging from the nature of neuronal activity to localization of brain functions [2].…”

“…While the 'dreamy state' can occur in isolation, it is often accompanied by fear and a peculiar form of abdominal discomfort associated with loss of contact with surroundings, and automatisms involving the mouth and gastrointestinal tract (licking, lip-smacking, grunting, and other sounds [10,11]. Intriguing descriptions and conceptual evolution followed in the writings of Critchton-Brown ('dreamy mental states'), Kinnier Wilson ('psychic variant'), Levin, Gibbs ('psychomotor seizures'), Lennox [1,[12][13][14]. Epileptic hallucinations entered modern neuro-physiologically based brain science with the work of Wilder Penfield.…”
