An 86-year-old man has diminished vibratory sensation at the knees and toes, although his reflexes are intact, temperature sensation is normal, and he feels well apart from headaches. Which one of the following is the most likely explanation?

1) peripheral neuropathy

2) normal age-related change

3) spinal cord lesion

4) small strokes

5) brain or brain stem tumor


1. vibration sense is usually the first to be lost


is that the classic clinical presentation of a peripheral neuropathy?


yup, eg in diabetes, Vit B deficiency, note that vibration is lost first,


but i meant if a peripheral neuropathy is classically symmetrical, right? correct me if i´m wrong
