Which symptom of hypercalcemia can affect cognitive function?

• A. Hyperactive reflexes
• B. Impaired memory
• C. Excessive energy
• D. Euphoria

Answer: (B)

Impaired memory is a recognized symptom of hypercalcemia that can significantly affect cognitive function. In conditions of elevated calcium levels in the blood, such as hypercalcemia, several neurological deficits can occur. Increased calcium interferes with neurotransmission and can disrupt normal brain function, leading to cognitive manifestations such as confusion, memory impairment, and even depression. While hyperactive reflexes could be seen in some neuromuscular conditions, it is not directly linked to hypercalcemia as prominently as cognitive changes. Excessive energy and euphoria may not be typical responses to hypercalcemia; rather, individuals often become lethargic or may experience a decrease in mental clarity. Thus, impairment of memory is the most relevant symptom in the context of hypercalcemia affecting cognitive function.
