Pharmacological Cognitive Enhancement

Early Phase 1

Completed

• Conditions: Fluid Inteligence; Modafinil; Healthy Young Subjects; Resting State Networks
• Interventions: Drug: Placebo; Drug: Modafinil

• Registration Number: NCT01684306
• Lead Sponsor: Università degli Studi 'G. d'Annunzio' Chieti e Pescara

Brief Summary

There is growing debate on the use of drugs that can promote cognitive enhancement. Amphetamine-like drugs have been employed as cognitive enhancers, but all of them have important side effects and may induce addiction. In our study, we will investigate the use of modafinil which, in recent years, has been proposed as cognitive enhancer. Modafinil appears to have less side effects compared to amphetamine-like drugs and we will analyzed whether the drug can influence cognitive performances and the brain resting state network activity of healthy young subjects.

Detailed Description

Subjects will be included in a double-blind, placebo-controlled study in which a single dose (100 mg) of modafinil will be administered. Both groups will be, before and three hours after administration of drug or placebo, tested for neuropsychological performances with the Raven's Advanced Progressive Matrices II set (APM).

Resting state functional magnetic resonance (rs-fMRI) will be also employed, before and after three hours, to study changes in the activity of resting state brain networks. Finally, with Diffusion Tensor Imaging (DTI) we will evaluate the structural connectivity of the two groups.

Arm && Interventions

Group	Intervention	Description
Placebo	Placebo	Study subjects received, in a double blind fashion, a placebo pill identical to the drug.
Modafinil	Modafinil	Modafinil (Provigil), a drug on the market since 1997, is employed for the treatment of narcolepsy and other sleep disorders. In recent years, modafinil has also been used off-label to treat cognitive dysfunction in psychiatric disorders such as schizophrenia and Attention Deficit/Hyperactivity Disorder (ADHD). Study subjects received, in a double blind fashion, either a single dose (100 mg) of modafinil.
