topicVitamin B12 Fatigue Randomized Trial
claimIntroduction Motivation is a key driver in achieving goals and performing daily tasks, involving cost-benefit valuations of the amount of effort required for a particular reward and can be influenced by socio-environmental factors and neurological conditions that may impact the brain reward circuitry.
