What does increased latency in nerve conduction studies indicate?

Increased latency in nerve conduction studies specifically indicates a conduction delay along the nerve pathway. This delay suggests that the time it takes for a nerve signal to travel from one point to another is prolonged. This could be due to a variety of factors, such as demyelination, where the protective myelin sheath around the nerve is damaged, causing slower signal transmission. Conditions like neuropathies or entrapment syndromes can also lead to increased latency as they impact the speed of nerve impulses.

Understanding the implications of increased latency is crucial for diagnosing peripheral nerve disorders and assessing the functional status of nerves. By quantifying how long it takes for signals to travel, healthcare professionals can identify areas of impairment and tailor treatment strategies accordingly.
