Cognitive functioning is a term referring to an individual’s ability to process to (thoughts) that should not deplete on a large scale in healthy individuals.
 It is defined as "the ability of an individual to perform the various mental activities most closely associated with learning and problem solving.
 Examples include verbal, spatial, psychomotor, and processing-speed ability."
 Cognition mainly refers to things like memory, the ability to learn new information, speech, understanding of written material.
 The brain is usually capable of learning new skills in the aforementioned areas, typically in early childhood, and of developing personal thoughts and beliefs about the world.
 Old age and disease may affect cognitive function, causing memory loss and trouble thinking of the right words while speaking or writing ("drawing a blank").
 Multiple sclerosis (MS), for example, can eventually cause memory loss, an inability to grasp new concepts or information, and depleted verbal fluency.
 Not all with the condition will experience this side effect, and most will retain their general intellect and the ability.
