Final answer:
Both increased and decreased levels of sodium (Na+) can result in confusion in an individual.
Step-by-step explanation:
Both increased and decreased levels of sodium (Na+) can result in confusion in an individual. Increased Na+ levels can disrupt the balance of electrolytes in the body, leading to confusion and other symptoms. On the other hand, decreased Na+ levels, known as hyponatremia, can also cause confusion and cognitive difficulties.
