Summary
Lysergic acid diethylamide (LSD) significantly impacts intellectual functioning, as shown by a study with 80 participants. Those under the influence scored an average of 10% lower on the Wechsler Adult Intelligence Scale compared to their baseline scores. In contrast, children assessed using the Wechsler Intelligence Scale for Children exhibited similar cognitive declines. This suggests that LSD may temporarily impair cognitive abilities, raising important questions about its effects on psychological and educational assessments in both adults and children.
