“…Dentre os principais distúrbios psiquiátricos associados ao desenvolvimento da síndrome podem-se citar: depressão, esquizofrenia, e ansiedade, sendo que a demência por corpos de levy também foi relatada como possível desencadeadora da doença (Mendonça et al, 2020). Segundo Alvez, Martelli, Fogagnolo e Nassif (2010), a fisiopatologia da síndrome ainda não é totalmente conhecida, podendo estar relacionada a diversos fatores, especialmente doenças orgânicas e lesões em determinadas áreas do cérebro.…”

“…Além dos antipsicóticos, pode-se associar ao tratamento os antidepressivos da classe dos inibidores seletivos de receptação de serotonina, como a fluvoxamina, sertralina e citalopram (Mendonça et al, 2020;Roulet & Zdanowicz, 2017;Tan et al, 2020). Esses antidepressivos são utilizados especialmente devido ao estado de fobia obsessiva em que o paciente se encontra, visto que acredita estar sendo infestado por parasitas na pele.…”

A síndrome de Ekbom leva os pacientes a apresentarem uma ideia delirante e persistente de que vermes e micróbios os infestam. Este artigo se trata de uma revisão de literatura, na qual foram utilizadas as seguintes plataformas como base de dados para pesquisa: PubMed, Lilacs, Cochrane Library e Scientific Eletronic Library On-line (SciELO). Foram usados relatos de caso publicados no período entre 2017-2021, nas línguas portuguesa e inglesa, que abordavam as medicações utilizadas no tratamento da Síndrome de Ekbom. A análise bibliográfica foi realizada por meio da leitura criteriosa dos artigos baseados nos critérios de inclusão e exclusão citados. Dos 79 resultados obtidos, apenas 11 abordaram de forma clara e objetiva sobre o tema da pesquisa, sendo utilizados na confecção do artigo. Dessa forma, dentre os principais distúrbios psiquiátricos associados ao desenvolvimento da síndrome podem-se citar: depressão, esquizofrenia, e ansiedade, sendo que a demência por corpos de levy também foi relatada como possível desencadeadora da doença, ademais, a prevalência da Síndrome de Ekbom é maior em mulheres entre 50-60 anos. Com isso, tornou-se perceptível que a síndrome de Ekbom é uma doença de considerável prevalência na sociedade, e que devido à sua fisiopatologia desconhecida necessita de pesquisas mais aprofundadas sobre o assunto.

“…Both patients had visual hallucinations, which is one of the core clinical features of DLB. Among four prior cases of delusional infestation diagnosed with DLB, two patients had visual hallucinations (7)(8)(9). Even in cases of suspected dementia in which a diagnosis of DLB had not been made, the coexistence of complex visual hallucinations and delusional infestation have been reported (15)(16)(17).…”

“…Ochiai et al reported a patient with delusional infestation and depressive symptoms with DLB who was treated with a combination of 5 mg/day of donepezil hydrochloride and 1.5 mg/day of aripiprazole, with temporary administration of mirtazapine ( 8 ). de Mendonça et al reported a DLB patient with delusional infestation and depressive symptoms who was treated with a combination of rivastigmine and citalopram ( 9 ). All patients in all cases, including ours, were safely treated with medication.…”

BackgroundDelusional infestation is characterized by delusions of being infested with parasites, vermin, or small insects and is frequently accompanied by tactile and visual hallucinations. Herein, we report two cases of dementia with Lewy bodies (DLB) with delusional infestation.Case presentationCase 1 was an 83-year-old man. At the age of 75, he began to show symptoms of rapid eye movement sleep behavior disorder. At the age of 83, he began to complain of visual hallucinations of people and delusional infestation with tactile and visual hallucinations of insects, resulting in the use of insecticides for non-existent insects. He also complained of mild amnesia and was admitted to our psychiatric ward for evaluation and treatment. After admission, the delusional infestation disappeared without any new medication. Based on our examinations, he was diagnosed with probable DLB with delusional infestation. He was treated with 5 mg/day of donepezil hydrochloride; his visual and tactile hallucinations disappeared, and the delusional infestation had not recurred at the 1-year follow-up. Case 2 was a 69-year-old woman. At the age of 60, she underwent clipping for subarachnoid hemorrhage (SAH). At the age of 65, she began to have visual hallucinations of people. At the age of 67, she began to complain of visual illusions in which she mistook lint for insects. At the age of 69, she developed delusional infestation and mild amnesia. She took various actions to get rid of these non-existent insects, including insecticide use, consulting an exterminator, and visiting several dermatologists. She eventually burnt her leg in an attempt to kill the non-existent insects. Based on our examinations, she was diagnosed with prodromal DLB in addition to SAH sequelae. We determined that her delusional infestation was caused by DLB rather than SAH sequelae based on the course of her symptoms. She was treated with a combination of 3 mg/day of donepezil hydrochloride and 12.5 mg/day of quetiapine. Thereafter, the delusional infestation partially improved, and she took no further action against non-existent insects.ConclusionDelusional infestation may be caused by DLB. Acetylcholinesterase inhibitors (AChEI) may be effective for delusional infestation in DLB, although antipsychotics may also be needed in severe cases.

We herein report a case of oral cenesthopathy that proceeded dementia with Lewy body (DLB). A 70-year-old female presented with oral cenesthopathy. She was diagnosed with major depression/late-onset schizophrenia and treated with paroxetine and perospirone. Subsequently, she developed severe parkinsonism. Her diagnosis changed to DLB based on clinical features and her magnetic resonance imaging, MIBG scintigraphy, and DAT scans. After tapering off paroxetine and perospirone, the patient was treated with donepezil and levodopa. The DLB symptoms, including oral cenesthopathy and parkinsonism, were relieved. This case indicates that oral cenesthopathy may occur as an early symptom of DLB.
