Does anorexia cause permanent brain damage?

Can the brain fully recover after anorexia?
3 Results showed: All brain structures in the recovered women were normal in volume and similar to those of control subjects. This study suggests that structural brain abnormalities are reversible with long-term recovery.
Does anorexia rewire the brain?
Summary: Even after weeks of treatment and considerable weight gain, the brains of adolescent patients with anorexia nervosa remain altered, putting them at risk for possible relapse, according to researchers.
