OBJECTIVE: To provide a comprehensive description of abnormal behaviors in patients with Gaucher disease type 3 (GD3) and relate these behaviors to demographic, neurodevelopmental, and neurologic characteristics.
METHODS: Thirty-four Egyptian patients with GD3 (mean age of 7.9 years) were enrolled in the study. They were selected based on parent report and/or physician observation of one or more abnormal behaviors documented in 2 settings and by 2 different individuals and/or by video recording. Behaviors were grouped into 4 categories: Crying/Withdrawal, Impatience/Overactivity, Anger/Aggression, and Repetitive Acts. Baseline and follow-up 6-12 monthly neurologic evaluations included IQ assessment and an EEG. All patients were receiving enzyme replacement therapy (30-60 IU/kg every 2 weeks) and were followed for periods of 3-10 years.
RESULTS: Supranuclear palsy of horizontal gaze, and of both horizontal and vertical gaze, bulbar symptoms, seizures, convergent strabismus, abnormal gait, and neck retroflexion were present in 97.1%, 50%, 55.9%, 29.4%, 29.4%, 20.6%, and 4.4% of patients, respectively. The most abnormal behavioral features were excessive anger (88.2%) and aggression (64.7%), and both were significantly higher in males. Anger/Aggression scores were highly correlated with IQ but not with either EEG/Seizure status or neurologic signs.
CONCLUSIONS: We describe behavioral problems with a unique pattern of excessive anger and aggression in patients with GD3. Defining these components using quantitative behavioral scoring methods holds promise to provide a marker of neurologic disease progression and severity.
