  2. Sensory neuronopathy - Wikipedia

    en.wikipedia.org/wiki/Sensory_neuronopathy

    The dorsal root ganglion contains cell bodies for sensory nerves including large, myelinated Aβ fibers which carry proprioception and tactile touch sensation to the brain via the dorsal column–medial lemniscus pathway and small, unmyelinated C fibers which carry thermal and pain sensation to the brain via the spinothalamic tract. [2]

  3. Dorsal root ganglion - Wikipedia

    en.wikipedia.org/wiki/Dorsal_root_ganglion

    A dorsal root ganglion (or spinal ganglion; also known as a posterior root ganglion [1]) is a cluster of neurons (a ganglion) in a dorsal root of a spinal nerve. The cell bodies of sensory neurons known as first-order neurons are located in the dorsal root ganglia. [2] The axons of dorsal root ganglion neurons are known as afferents.

  4. Complex regional pain syndrome - Wikipedia

    en.wikipedia.org/wiki/Complex_regional_pain_syndrome

    Dorsal root ganglion stimulation is a type of neurostimulation that is effective in the management of focal neuropathic pain. The FDA approved its use in February 2016. The ACCURATE Study demonstrated superiority of dorsal root ganglion stimulation over spinal (dorsal column) stimulation in the management of CRPS and causalgia. [62]

  5. Dorsal root of spinal nerve - Wikipedia

    en.wikipedia.org/wiki/Dorsal_root_of_spinal_nerve

    The root emerges from the posterior part of the spinal cord and travels to the dorsal root ganglion. The dorsal root ganglia contain the pseudo-unipolar cell bodies of the nerve fibres which travel from the ganglia through the root into the spinal cord. The lateral division of the dorsal root contains lightly myelinated and unmyelinated fibres ...

  6. Tabes dorsalis - Wikipedia

    en.wikipedia.org/wiki/Tabes_dorsalis

    Tabes dorsalis is a late consequence of neurosyphilis, characterized by the slow degeneration (specifically, demyelination) of the neural tracts primarily in the dorsal root ganglia of the spinal cord (nerve root). These patients have lancinating nerve root pain which is aggravated by coughing, and features of sensory ataxia with ocular ...

  7. Anesthesia dolorosa - Wikipedia

    en.wikipedia.org/wiki/Anesthesia_dolorosa

    Dorsal root entry zone lesioning, damaging the point where sensory nerve fibers meet spinal cord fibers, produced favorable results in some patients and poor results in others, with incidence of ataxia at 40%. Patient numbers were small, follow-up was short and existing evidence does not indicate long term efficacy.

  8. Adie syndrome - Wikipedia

    en.wikipedia.org/wiki/Adie_syndrome

    This second set of symptoms is caused by damage to the dorsal root ganglia of the spinal cord. Adie's pupil is supersensitive to ACh so a muscarinic agonist (e.g. pilocarpine) whose dose would not be able to cause pupillary constriction in a normal patient, would cause it in a patient with Adie's Syndrome. The circuitry for the pupillary ...

  9. Erythromelalgia - Wikipedia

    en.wikipedia.org/wiki/Erythromelalgia

    The neuropathological symptoms of primary erythromelalgia arise from hyperexcitability of C-fibers in the dorsal root ganglion. Specifically, nociceptors (neurons responsible for the sensation and conduction of painful stimuli) appear to be the primarily affected neurons in these fibers. This hyperexcitability results in the severe burning pain ...
