In the study carried out between March 2016 to July 2017, researchers examined the characteristics of recognition of the six facial expressions of "happiness," "sadness," "fear," "anger," "surprise," and "disgust". They researched 107 people aged 60 years and more, diagnosed with dementia. In the end, it was revealed that a patient suffering from Lewy Body Disease, could recognise happiness and it was the only facial expression that was unaffected by ageing, onset, and duration of the disease. These people also faced difficulty in understanding the expression of fear, the study found.
