ABSTRACT
This case report aimed to describe various psychiatric manifestation and treatment course in a patient with DiGeorge syndrome. Psychiatric symptoms and treatment course in a female patient with DiGeorge syndrome were described. This patient showed psychotic symptoms, mood symptoms, and intellectual disability. As well as various psychiatric symptoms, treatment response and sensitivity of side effect by antipsychotics were different from typical characteristics in psychiatric disorders. This case suggests that the genetic defect in DiGeorge syndrome might have a great association with psychiatric problems and response of antipsychotics.
ABSTRACT
OBJECTIVES: Most studies of hippocampal metabolism(HM) in amnestic mild cognitive impairment(aMCI) gave inconsistent results. Our objective was to evaluate the effect of amyloid-beta(Aβ) status on hippocampal metabolism in aMCI.METHODS: Overall, 23 aMCI underwent three-dimensional magnetic resonance imaging(MRI), ¹⁸F-fluorodeoxyglucose-positron emission tomography(¹⁸FDG-PET) and ¹⁸F-Fluorbetaben amyloid positron emission tomography (amyloid-PET). According to Aβ status on amyloid PET, 23 aMCI were classified as either Aβ+aMCI(N=13) or Aβ−aMCI(N=10). The primary outcome was HM using ¹⁸FDG-PET and we investigate the difference on HM between Aβ+aMCI and Aβ−aMCI using analysis of variance(ANOVA) model, after controlling hippocampal volume.RESULTS: We found that HM was more decreased in Aβ+aMCI than Aβ−aMCI. This result was not changed after controlling hippocampal volume.CONCLUSION: Our findings suggest that Aβ+ is associated with decreased HM, regardless of hippocampal volume, in aMCI.
