Anorexia Nervosa
Conditions
Brief summary
Aims of this follow-up study are to investigate effects of anorexia nervosa on brain structure and functions in adolescence.
Detailed description
Anorexia nervosa is severe mental health problem with increased incidence rates in adolescence. Etiology of anorexia nervosa is still mostly unkonwn. Adolescence is also critical period of brain development. Aims of this follow-up study are to investigate effects of anorexia nervosa on brain structure and functions in both acute and remission state of anorexia nervosa in adolescence. Study group are young anorexia nervosa patients, and control group are healthy same-aged students. Research methods include non-invasive brain imaging methods such as Transcranial Magnetic Stimulation (TMS), and Magnetic Resonance Imaging (MRI). Other research methods are assessment of body composition, laboratory tests, self-rated questionnaires and psychiatric interview.
Interventions
Neuroimaging, body compostion, laboratory tests and psychiatric interview in study and in control groups.
