Sensory neuronopathies (or ganglionopathies) represent a rare group of peripheral nerve disorders characterised by degeneration or dysfunction of dorsal root ganglia (DRG) or trigeminal sensory neurons.1 2 Large sensory fibres are typically affected, resulting in loss of proprioception and pseudoathetoid posturing of limbs, along with loss of vibration, touch and deep tendon reflects. Acute-onset and severe sensory and autonomic deficits with no motor dysfunction, typically preceded by a febrile illness, with poor recovery, and often fatal outcome are the hallmark features of acute sensory and autonomic neuronopathy (ASANN). Some other autoimmune conditions can increase your chances of developing dysautonomia.

On all occasions supramaximal stimulation of the nerves was performed. It is likely that improvement with treatment is limited by destruction of the cell body of the sensory neuron. This can improve your quality of life regardless of the severity of the condition. Pathologically and electrophysiologically, ASANN is characterized by an extensive ganglionopathy affecting sensory and autonomic ganglia with preservation of motor neurons. Rapid neurophysiological screening for sensory ganglionopathy: A novel It can occur secondary to cerebellar dysfunction (cerebellar ataxia) or because of dysfunction within the peripheral or central sensory pathways (sensory ataxia). Subacute autonomic neuropathies can be further divided into dysautonomia associated with sensory and motor neuropathy, dysautonomia associated with malignancy or idiopathic autoimmune autonomic ganglionopathy (AAG).
