Psychological and cognitive evaluation of autism in a patient with MOMO syndrome: a case report and literature review.

MOMO is an acronym for macrosomia, obesity, macrocephaly and ocular abnormalities. The syndrome was first described in 1993, with a total of nine patients published thus far. All the cases presented intellectual disability and in one case autism was described. We present a new case of a patient with MOMO syndrome, who consulted for hallucinatory phenomena. He completed a neuropsychological, clinical and cognitive evaluation, showing a borderline intelligence quotient and fulfilled the criteria for autism spectrum disorder. This is the first neurocognitive evaluation of a patient with MOMO, supporting the use of standardized scales in order to assess the autism and other psychiatric comorbidities in patients with genetics syndromes.
