Effects of Cannabidiol on Memory and Attention in Adults Aged 60-70: A Pilot Study
Sponsor: Medical University of Silesia
Summary
This pilot study aims to investigate the effects of a single oral dose of cannabidiol (CBD) on memory and attention in healthy adults aged 60 to 70 years. CBD is a naturally occurring compound found in cannabis that does not produce the intoxicating effects associated with THC. The main research question is whether CBD can improve episodic memory (the ability to remember previously learned information), working memory (the ability to temporarily hold and use information), and attention compared with placebo. The researchers hypothesize that participants will perform better on memory and attention tasks after receiving CBD than after receiving placebo. The study will involve approximately 50 healthy adults aged 60 to 70 years. Each participant will attend two study sessions, scheduled 14 to 30 days apart. During one session, participants will receive a single oral dose of 25 mg CBD, while during the other session, they will receive a placebo capsule containing no CBD. The order of administration will be randomly assigned, and neither the participants nor the researchers assessing their performance will know which capsule was administered during each session. Memory and attention will be evaluated using standardized memory tests and computer-based cognitive tasks. The findings will provide preliminary evidence on the potential effects of CBD on cognitive functioning in older adults.

Interventions
Cannabidiol (CBD)
Single oral administration of a softgel capsule containing 25 mg of cannabidiol (CBD). Each participant will receive CBD during one of the two experimental sessions, according to the randomized treatment sequence.
Placebo
Single oral administration of a placebo softgel capsule containing medium-chain triglyceride (MCT) oil only. The placebo capsules will be visually indistinguishable from the CBD capsules. Each participant will receive placebo during one of the two experimental sessions, according to the randomized treatment sequence.
