[Clinical Picture] Feeding dystonia, chorea, psychosis, and self-mutilation in an African patient with neuroacanthocytosis syndrome

A 34-year-old woman with a 2-year history of progressively worsening difficulties in walking, eating and swallowing, presented to our department. The patient's sister reported observing unusual behaviours over the past 6 months: she said her sister had been taking her meals to eat alone in the bathroom and had crafted a doll from leaves gathered from local trees, referring to it as her son (figure A). Additionally, she had been experiencing low mood and general cognitive decline, including memory and attention deficits, along with personality changes such as increased impulsivity and aggression.
