Sjogren's in particular is known for this, and for sometimes having central nervous system (CNS) effects as well. Often, in SJogren's, the cell bodies in the dorsal root ganglia are attacked, leading to what is more properly called a Neuronopathy, which may not be length-dependent, and can involve many parts of the body, not just the extremities.
