Abstract

We evaluated Gamalate® B6 (GB6) in patients with borderline intellectual functioning (BIF) or mild intellectual development disability (IDD). This was a prospective phase IV observational pilot study in 30 patients who underwent neuropsychological evaluation during treatment with GB6 for 12 weeks. 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. 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.
