Computed tomography of anorexia nervosa

Area of Science:

• Neurology
• Psychiatry
• Radiology

Background:

• Anorexia nervosa is a complex eating disorder with potential neurological implications.
• Previous studies suggested reversible cerebral atrophy in patients with this condition.

Purpose of the Study:

• To investigate and confirm reversible cerebral atrophy in anorexia nervosa using computed tomography (CT).
• To correlate brain tissue changes with cerebral function through psychological testing.

Main Methods:

• Computed tomographic (CT) scans were performed on 23 patients with anorexia nervosa.
• Follow-up CT scans were conducted on 11 patients after weight restoration.
• Psychological tests were administered concurrently with CT scans.
• Statistical analysis (Student t-test) was applied to the data.

Main Results:

• Marked enlargement of cortical sulci and interhemispheric fissures was observed in 21 of 23 patients.
• These brain changes reversed in 11 patients after 4 weeks of normal weight.
• Statistically significant correlations were found between brain changes and cerebral function (p=0.01).

Conclusions:

• Anorexia nervosa is associated with reversible cerebral atrophy.
• The illness involves significant organic brain changes alongside psychodynamic factors.
• These findings highlight the role of organic brain lesions in the course of anorexia nervosa.
