| Outline of Final Research Achievements |
Anorexia nervosa (AN) is a psychiatric disorder characterized by a low body weight and abnormal perception of a body shape. Previous studies indicated abnormalities of neuroinflammation and serotonin (5-HT) system in AN patients. Here, we aimed to clarify an alteration of activated microglia, which plays a major role in the neuroinflammation in living human brain, and 5-HT transporter (5-HTT) in AN using positron emission tomography (PET).
Twenty female AN patients (mean age±SD, 25.0±6.0 years old, mean BMI±SD, 14.1±1.3) and 20 healthy female subjects (22.8±3.7years old, BMI 20.6±2.4) underwent activated microglia and 5-HTT PET measurements and neurocognitive tasks. We showed increased activated microglia and reduced 5-HTT availability in AN patients.
