In most—but not all—cases, autonomic neuropathy occurs alongside other forms of neuropathy, such as sensory neuropathy.Autonomic neuropathy is one cause of malfunction of the autonomic nervous system, but not the only one; some conditions affecting the brain or spinal cord also may cause autonomic dysfunction, such as multiple system atrophy, and therefore, may cause similar symptoms to autonomic neuropathy.The signs and symptoms of autonomic neuropathy include the following:

Urinary bladder conditions: bladder incontinence or urine retention
Gastrointestinal tract: dysphagia, abdominal pain, nausea, vomiting, malabsorption, fecal incontinence, gastroparesis, diarrhoea, constipation
Cardiovascular system: disturbances of heart rate (tachycardia, bradycardia), orthostatic hypotension, inadequate increase of heart rate on exertion
Respiratory system: impairments in the signals associated with regulation of breathing and gas exchange (central sleep apnea, hypopnea, bradypnea). Skin : thermal regulation, dryness through sweat disturbances
Other areas: hypoglycemia unawareness, genital impotence

Neuritis
Neuritis is a general term for inflammation of a nerve or the general inflammation of the peripheral nervous system. Symptoms depend on the nerves involved, but may include pain, paresthesia (pins-and-needles), paresis (weakness), hypoesthesia (numbness), anesthesia, paralysis, wasting, and disappearance of the reflexes. Causes of neuritis include:

Signs and symptoms
Those with diseases or dysfunctions of their nerves may present with problems in any of the normal nerve functions. Symptoms vary depending on the types of nerve fiber involved. In terms of sensory function, symptoms commonly include loss of function ("negative") symptoms, including numbness, tremor, impairment of balance, and gait abnormality. Gain of function (positive) symptoms include tingling, pain, itching, crawling, and pins-and-needles.
Juvenile hyaline fibromatosis (also known as "Fibromatosis hyalinica multiplex juvenilis," "Murray–Puretic–Drescher syndrome") is a very rare, autosomal recessive disease due to mutations in capillary morphogenesis protein-2 (CMG-2 gene). It occurs from early childhood to adulthood, and presents as slow-growing, pearly white or skin-colored dermal or subcutaneous papules or nodules on the face, scalp, and back, which may be confused clinically with neurofibromatosis. The World Health Organization, 2020, reclassified the papules and nodules that occur in juvenile hyaline firbromatosis as one of the specific benign types of tumors in the category of fibroblastic and myofibroblastic tumors. Presentation
This condition is characterised by abnormal growth of hyalinized fibrous tissue with cutaneous, mucosal, osteoarticular and systemic involvement. Clinical features include extreme pain at minimal handling in a newborn, gingival hypertrophy, subcutaneous nodules, painful joint stiffness and contractures, muscle weakness and hypotonia. Genetics
This condition is due to mutations in the anthrax toxin receptor-2 (ANTXR2) gene. This gene is also known as capillary morphogenesis protein-2. This gene is located on the long arm of chromosome 4 (4q21.21). Management
There is no presently known curative treatment for this condition.Management is supportive

Prognosis
This is very poor with a median age at death of 15 months. Epidemiology
84 cases have been reported as of 2018. See also
