How can short-term memory loss be assessed in a neurological exam?

Short-term memory loss can be effectively assessed by asking the patient to recall three unrelated words. This method directly evaluates the patient's ability to encode, store, and retrieve new information, which is central to short-term memory function. By using a simple task such as recalling three unrelated words, the examiner can observe the patient's cognitive processing and immediate recall capabilities, both of which are crucial for assessing short-term memory.

Analyzing reaction times focuses on the speed of response to stimuli, which may provide insights into cognitive processing but does not directly assess memory. Performing a finger-to-nose test is primarily a coordination and motor function assessment, not specifically related to memory evaluation. Measuring blood pressure is important for overall health and can indicate some neurological status, but it does not assess memory capabilities. Thus, recalling three unrelated words is the most direct and effective method for assessing short-term memory in a neurological exam.
