“Capgras” Delusions Involving Belongings, Not People, and Evolving Visual Hallucinations Associated with Occipital Lobe Seizures

Abstract

Capgras syndrome is characterized by the delusional belief that a familiar person has been replaced by a visually similar imposter or replica. Rarely, the delusional focus may be objects rather than people. Numerous etiologies have been described for Capgras to include seizures. Similarly, visual hallucinations, both simple and complex, can occur secondary to seizure activity. We present, to our knowledge, the first reported case of visual hallucinations and Capgras delusions for objects that developed secondary to new onset occipital lobe epilepsy. We then discuss the possible underlying neurologic mechanisms responsible for the symptomatology.

Epileptic Capgras-Like Delusions in a Patient with Right Frontal Meningioma: Case Report

“…The occurrence of Capgras syndrome has been documented in postictal delirium, such as in the Kim's case described above [2] and in other reports [4][5][6], but it was also described in the interictal period [7][8][9]. For example, Chawla and Virmani [7] reported the case of a young man suffering from temporal lobe epilepsy since he was 19 years old.…”

“…In the context of epilepsy-associated Capgras syndrome, reduplicative paramnesia may appear because of ictal or postictal disinhibition of both the dominant and nondominant hemispheres, respectively, involved in recognition and in perceptual integration [4, 5]. There is little information concerning the pathomechanisms of the 3 types (ictal, postictal, and interictal) of Capgras-like delusions.…”

Wahnhafte Missidentifikation und gewalttätiges Verhalten – Risikoabschätzung und Management

“…Trotzdem wird in der Literatur häufig der Begriff "Wahnhaftes Missidentifikations-Syndrom" verwendet. Neben dem Auftreten von WM bei schizophrenen und organischen Störungen, ist es auch im Zusammenhang mit Hypothyreose [13], Temporallappenischämie [14], Okzipitallappenepilepsie [15], Multipler Sklerose [16], Limbischer Enzephalitis [17] und Posttraumatischer Belastungsstörung [18] beschrieben worden.…”

Avaliação qualitativa e quantitativa por SPECT cerebral das alterações funcionais associadas ao Lúpus Eritematoso Sistêmico forma Neuropsiquiátrica (LESNP)

“…O SISCOM revelou hiperperfusão no LT e LO (reperfusão) e melhora do quadro de alucinações e memória da paciente. O lobo occipital (LO), responsável pela área visual, corresponde também pelas alucinações visuais(LILLY et al, 2018) e um aumento de perfusão nesta área, justificou a melhora da paciente no quadro (LAROCQUE;WAGNER, 2015). O SISCOM foi determinante em mostrar essa reperfusão, já que a análise visual não havia discriminado esse fenômeno.…”
