Serum cholesterol and perception of anger and sadness

Analysis of cholesterol levels in 34 forensic patients indicated significant associations with measures of the patients' perceptions of the emotional content in auditory stimuli. In particular, patients with low cholesterol showed hypersensitivity in the detection of anger and sadness. The authors hypothesize the involvement of serotonin in the hypersensitivity effects. Organicity and age were ruled out as contributing factors.
