Abstract
BACKGROUND: We evaluated Gamalate® B6 (GB6) in patients with borderline intellectual functioning (BIF) or mild intellectual development disability (IDD). PATIENTS AND METHODS: This was a prospective phase IV observational pilot study in 30 patients who underwent neuropsychological evaluation during treatment with GB6 for 12 weeks. RESULTS: In comparison with baseline, the responses were positive, with a significant improvement in hyperactivity (51.7%), irritability (35.5%), and logorrhea (50%), and no sedative effect. The Clinical Global Impressions - Severity (CGI-S) score was much improved or very much improved in 73% of cases. Reaction time was better with fewer errors, thus indicating an improvement in attentional processes. A statistically significant result was obtained for the number of movements used to solve the problem and for the total number of correctly solved problems. CONCLUSION: In this pilot study, GB6 was effective and well tolerated in cases of ADHD and challenging behavior in young adults with borderline-to-mild BIF/IDD. However, given the small number of patients involved and the uncontrolled nature of the study, these results should be viewed cautiously.
