Which of the following is a sign of reduced cognition?

Memory loss is a notable sign of reduced cognition. It indicates difficulties in retaining or recalling information, which can stem from various cognitive impairments or conditions such as dementia, brain injuries, or general age-related decline in mental function. When cognitive abilities are compromised, individuals may struggle to remember recent events, learn new information, or utilize previously learned material effectively.

On the other hand, increased alertness, a focused approach to tasks, and improved reaction time are typically associated with enhanced cognitive functioning. Increased alertness indicates heightened awareness of one's surroundings, which often correlates with better cognitive performance. Similarly, focusing on tasks suggests a strong ability to concentrate, while improved reaction time reflects efficient processing and response capabilities, all of which are characteristics of good cognitive health.
