Cognitive training versus brain games: similar language, different evidence
These terms overlap in everyday conversation, but research protocols and consumer games are not interchangeable.
Structured cognitive training
Research programs usually define the skill being trained, session schedule, participant group, comparison condition, and outcome measures.
Commercial brain games
Consumer programs may borrow similar tasks, but their design and claims vary widely. Evidence for one program should not be assumed to apply to another.
General mental stimulation
Reading, learning, hobbies, puzzles, games, and social activities can all be mentally engaging without being formal cognitive training.
Why labels matter when shopping
A product can call itself brain training without meeting the design of a clinical cognitive training study. Look past the category name and inspect the actual routine and evidence.

Near transfer and far transfer
One useful distinction is transfer. Near transfer means improvement on tasks that resemble the training. Far transfer means improvement on more distant abilities or everyday functioning. A program can improve practiced skills without establishing broad effects across unrelated cognitive abilities.
Why study design changes the answer
Results can depend on the participant group, training schedule, comparison activity, outcome test, and length of follow up. A study in healthy adults should not automatically be used to make a treatment claim for people with cognitive impairment. The reverse is also true.
