Impaired recognition of emotion in facial expressions
Some of the previous studies argue that the visual attention mechanisms underlying worse performance in AD patients might be related the fact that AD patients spend less time exploring the face area compare to the off-face areas . The clinical diagnosis of AD was made by a psychiatrist based on a clinical interview with the people with AD and their caregivers and on cognitive screening tests, laboratory tests and imaging studies. Discussion In this study among older adults, we examined the association between cognitive function and recognition of emotions in facial expressions across the full continuum of cognitive capacity. Impaired social cognition in mild Alzheimer disease. Participants were then shown five photographs of the same individual with each photograph depicting one of the five different facial expressions of emotions the face stimuli were the same as those used in other subtest of FAB. It is essential for the future studies to conduct more in-depth investigations of the effects of the AD on the processing of facial expression.
Preserved recognition and selection of facial expression of happiness in mild Alzheimer’s Disease
Recognition of facial emotion in nine individuals with bilateral amygdala damage
No time limits were set, and no feedback was provided about performance during the test trials. It will be so beneficial if future studies to utilize both behavioral and structural and functional MRI scanning to provide more robust evidence to support the previous findings. It would be important to examine whether different types of stimuli, e. The people with AD completed assessments about facial recognition tasks, quality of life QoL , cognition, and their awareness of their disease.

Am J Geriatr Psychiatry. Int J Geriatr Psychiatry. We examined participants' recognition of facial expressions conveying the six basic emotions previously examined by McCown et al. Recommended or similar items. In a second stage, participants were evaluated within a maximum of 30 days using the PHQ-2, MMSE, and the tasks with static and dynamic stimuli of facial expressions of emotions. This result is in line with previous studies showing that happiness is usually better recognized than the other emotions in FTD and AD patients . Task with static stimuli The Penn Emotion Recognition Test comprises 96 color photographs of facial expressions of basic emotions happiness, sadness, anger, fear and disgust , as well as faces showing no emotion neutral in static stimulus.
Evaluation of emotional blunting in behavioral variant frontotemporal dementia compared to Alzheimer's disease. A neuropsychological battery would provide a more thorough exploration of the cognitive and perceptual components of emotion perception. The parametric variables were described by their mean and standard deviations SD , and the non-parametric variables were described by their percentages. Our sample did not include any people with AD who had familial AD. This might be particularly difficult for the AD patients as their cognitive resources are limited.
