While no cognitive changes were noted in the rats given ecstasy at an earlier age, memory and learning deficiencies were noted in the group exposed to ecstasy during days 11-20. The ecstasy-induced disruption in both sequential and spatial reference memory-based learning was long-term and was still apparent after this group reached adulthood.
