Recognition of facial emotional expression in amnestic mild cognitive impairment.

We examined whether recognition of facial emotional expression would be affected in amnestic mild cognitive impairment (aMCI). A total of 50 elderly persons met the initial inclusion criteria; 10 were subsequently excluded (Geriatric Depression Score > 5). 22 subjects were classified with aMCI based on published criteria (single domain aMCI [SD-aMCI], n = 10; multiple domain aMCI [MD-aMCI], n = 12); 18 subjects were cognitively normal.

Magnetic resonance analysis of amygdalar volume in Alzheimer's disease.

Purpose Of Review: With the rising prevalence of Alzheimer's disease, there is an increasing need for better comprehension of its pathophysiology. The purpose of this article is to review recent studies investigating the association between amygdalar volume and clinical symptoms in Alzheimer's disease. The first part describes the technique of MRI segmentation of amygdala.
