Superior Olivary Nucleus Degeneration

Superior Olivary Nucleus (SON) degeneration is a condition where the nerve cells in the SON deteriorate, affecting various functions of the auditory system. In this comprehensive guide, we’ll delve into the types, causes, symptoms, diagnosis, and treatment options for SON degeneration, explained in simple terms for better understanding.

Types of Superior Olivary Nucleus Degeneration:

There are two primary types of SON degeneration: primary and secondary. Primary degeneration occurs due to direct damage to the SON cells, while secondary degeneration is caused by damage to neighboring structures affecting the SON.
