Reversible brain atrophy and reversible developmental retardation in a malnourished infant

An 11-month-old infant suffering from microcephalus, developmental delay, severe failure to thrive and marked cortical atrophy on brain CT is presented. The cause of this condition was total calorie malnutrition induced by the emotional dysfunction of the mother. Improvement of the maternal-infant relationship, combined with appropriate nutrition, transformed the infant within 2 months into a normally developing baby with body weight and head circumference within the normal percentile range. A corresponding improvement was found in the brain CT.
