To examine the relationship between different types of dementia and hippocampal volume.
Hippocampal volume was measured by magnetic resonance imaging in patients with Alzheimer's disease (n = 22), vascular dementia (n = 14), mild cognitive impairment (n = 12) or pseudodementia (n = 16), and in healthy control subjects (n = 11). The Mini Mental State Examination was used to stratify subjects according to cognitive function.
Hippocampal volume was reduced by 42% in Alzheimer's disease, 21% in vascular dementia, 15% in mild cognitive impairment and 13% in pseudodementia compared with controls. The severity of dementia increased in line with decreasing hippocampal volume.
Measurement of hippocampal volume may facilitate differentiation between dementia subtypes. There was a relationship between reduced hippocampal volume and the degree of cognitive impairment.
研究不同类型痴呆与海马体积之间的关系。
采用磁共振成像测量阿尔茨海默病患者(n = 22)、血管性痴呆患者(n = 14)、轻度认知障碍患者(n = 12)或假性痴呆患者(n = 16)以及健康对照者(n = 11)的海马体积。使用简易精神状态检查表根据认知功能对受试者进行分层。
与对照组相比,阿尔茨海默病患者的海马体积减少了42%,血管性痴呆患者减少了21%,轻度认知障碍患者减少了15%,假性痴呆患者减少了13%。痴呆的严重程度随着海马体积的减小而增加。
测量海马体积可能有助于区分痴呆亚型。海马体积减小与认知障碍程度之间存在关联。
