Attention is the capacity of the central nervous system to select and prioritize relevant information, whereas concentration refers to the ability to sustain attention on a given activity for a defined period of time. These processes are part of the broader spectrum of cognitive and executive functions, together with learning, thinking, reasoning, memory, problem-solving, and decision-making.

Efficient and flexible cognitive functioning is important for adaptation to novel situations, the management of social interactions, and the achievement of daily goals. Impairment of executive functions may affect concentration capacity, activity organization, time management, impulse control, emotional regulation, and performance at work or in everyday activities.

The HumanoPedia medical dictionary provides essential information on attention, concentration, and cognitive functions. This facilitates a clearer understanding of how these processes contribute to central nervous system health and mental performance.
