416Gratification phenomena in infants, also known as infantile masturbation, are self-stimulatory behaviors that have tendency to become a habit 1 . They are generally not well recognized by general practitioners and pediatricians, resulting in misdiagnoses that often include epilepsy, recurrent abdominal pain, and paroxysmal dystonia or dyskinesia 1 . Gratification phenomena may begin from very early age, typically after two to three months of age 2,3 . Stereotypic motor manifestations include lower limbs scissoring posture and repetitive pelvic movements with rubbing the thighs together and rocking the genital region against the bed or other objects, such as the infant seat or its belt [4][5][6] . The paroxysmal movements are typically associated with grunting, facial flushing, and irregular breathing, which are all followed by sweating and exhaustion. The infant may not appear ABSTRACT: Background: Infantile gratification phenomena are self-stimulatory behaviors that are often misdiagnosed as epilepsy. Although the prognosis is thought to be benign, limited long-term follow-up studies exist. This was the objective of our study in addition to exploring the risks of future developmental, behavioral, or neurological abnormalities. Methods: Series of consecutive infants with gratification phenomena were identified both retrospectively and prospectively over an eight year period from a single pediatric neurology service. The diagnosis was based on descriptive history, review of videotaped events, lack of neurological or developmental abnormalities, and normal routine electroencephalogram. Results: Nineteen infants were followed for 3-11 years (mean 7.1). Their ages ranged between 4-13 months (mean 7) with 79% females. The diagnosis was not reached by the referring physician and 74% were misdiagnosed as epilepsy or movement disorder. The episodes recurred with variable frequency with gradual reduction in number and increase in length of attack-free periods with advancing age. Complete remission was noted in all patients by age 1-3 years (mean 1.9). However, 4 children (21%) developed features of attention deficit hyperactivity disorders (ADHD) on long-term follow up. In this group, the gratification phenomena appeared at a younger age with higher attack frequency. Conclusions: Gratification phenomena in infants are benign and self-limited, often spontaneously disappearing by two years of age. A correlation with future ADHD was found; however, larger prospective studies are needed to further examine this possible association.
