  • Editorial index: substances classified under stimulant. This index does not assert a combined effect. Compounds associated with increased arousal; mechanisms and risks differ.

  • Editorial index: substances classified under dopamine transporter. This index does not assert a combined effect. A membrane transporter involved in dopamine reuptake. Human PET studies can measure occupancy without establishing general cognitive benefit.

  • Editorial index: substances classified under dopamine. This index does not assert a combined effect. A neurotransmitter whose extracellular availability is influenced by dopamine transporters. Increased signaling is not a universal benefit.

  • Editorial index: substances classified under wakefulness. This index does not assert a combined effect. The experience of being awake rather than sleepy. Reported wakefulness is distinct from performance and measured ability to remain awake.

  • Editorial index: substances classified under measured wakefulness. This index does not assert a combined effect. Sleep latency or wake-maintenance measurements under defined laboratory conditions; not interchangeable with subjective alertness.

  • Acute PET findings in healthy men; target occupancy is distinct from a clinical outcome.

Relationship nodes connect multiple concepts in one sourced statement. Member roles identify the substance, biological target, measured outcome, or exposure context. Editorial index relationships group classifications. Connections are not recommendations to combine substances.
