A double-blind, intra-individual cross-over comparison of the mental performance of 18 aging, non-deteriorated individuals during two 4-week periods of piracetam (1-acetamide-2-pyrrolidone) and placebo administration was performed using conventional and computerized perceptual-motor tasks. In a majority of these tasks the subjects did significantly better when on piracetam than on placebo, a finding consistent with ratings completed by two independent observers. The findings indicate new avenues for the treatment of individuals with reduced mental performance possibly related to disturbed alertness--a neglected group of psychiatric conditions.
对18名未出现精神衰退的老年人在两个为期4周的阶段分别服用吡拉西坦(1-乙酰氨基-2-吡咯烷酮)和安慰剂期间的心理表现进行了双盲、个体内交叉比较,采用了传统的和计算机化的感知运动任务。在大多数这些任务中,受试者服用吡拉西坦时的表现明显优于服用安慰剂时,这一发现与两名独立观察者完成的评分一致。这些发现为治疗可能与警觉性障碍相关的心理表现下降的个体指明了新途径,而警觉性障碍是一组被忽视的精神疾病。
