Abstract
Objective: Closing-in (CI) consists in copying drawings near to (near-CI) or superimposed on (adherent-CI) the model and often occurs in dementia and mild cognitive impairment (MCI). We assessed whether a visuo-constructional task not requiring a grapho-motor response is sensitive to identify CI in Alzheimer's disease (AD), fronto-temporal dementia (FTD), vascular dementia (VD), and MCI.
Method: We enrolled a sample of 162 patients with dementia (AD, FTD, or VD), 66 individuals with MCI, and 20 healthy adults (HAs) who completed a neuropsychological assessment and the Stick Design test that requires arranging matches for reproducing geometrical figures.
Results: CI in the Stick test was slightly (but not significantly) more frequent than that observed in the copying drawing task. CI frequency on both tests was high and similar in AD and FTD and lower in VD and MCI. On both tests, near-CI was the most common error in VD and MCI, whereas adherent-CI prevailed in patients with AD; a similar percentage of near-CI and adherent-CI was observed in FTD. Last, in the participants with dementia and MCI, the number of CIs was significantly correlated with an index of control and executive functions but not with spatial short-term memory.
Conclusions: CI occurs with the same frequency in AD, VD, and FTD, but the prevalent type of CI varies across syndromes. The Stick Design test is a useful task to assess CI and its specific forms in dementia and MCI. (PsycINFO Database Record (c) 2020 APA, all rights reserved).
지난 달에 나온 논문입니다. CI를 두 가지로 구분해서 보네요. near는 근접하여 그리는 것이고 adherent는 제시된 자극 바로 위에 겹치듯 그리는 것을 의미하는 듯합니다.
CI 발생 빈도를 살펴보면 AD와 FTD에서 비슷하고 VD와 MCI에서는 상대적으로 적은 것으로 나타납니다. near-CI는 VD와 MCI에서 흔한 데 반해 adherent-CI는 AD에서 흔한 것으로 나타납니다. FTD 안에서 near-CI와 adherent-CI의 발생 빈도는 비슷합니다. 끝으로 dementia와 MCI에서 CI 갯수는 executive functions과 상관 있고 spatial short-term memory와는 관련 없는 것으로 나타납니다.
