Among disorders that cause sensory loss, the most distinctive are those that affect the sensory ganglia. These disorders are called sensory neuronopathies or sensory ganglionopathies. The importance of sensory ganglia, in addition to the unique topography of sensory loss that occurs when they are diseased, lies in their close association with general medical disorders, and paraneoplastic disorders in particular. Furthermore, ganglia may be susceptible to autoimmune attack because of the fenestrated endothelial cells that form a permeable blood–nerve barrier.
