True about autonomic neuropathy are all except

Autonomic neuropathy is a group of symptoms that occur when there is damage to the nerves that manage every day body functions. These functions include blood pressure, hea rate, sweating, bowel and bladder emptying, and digestion Sign and symptoms: Urinary bladder conditions: bladder incontinence or urinary retention Gastrointestinal tract: dysphagia, abdominal pain, nausea, vomiting, malabsorption, fecal incontinence, gastroparesis, diarrhea, constipation Cardiovascular system: disturbances of hea rate (tachycardia, bradycardia), ohostatic hypotension, inadequate increase of hea rate on exeion Respiratory system: impairments in the signals associated with regulation of breathing and gas exchange (central sleep apnea, hypopnea, bradypnea). Nervous system: pupillary defect, exaggerated hippus, dizziness or lightheadedness. Other areas: hypoglycemia unawareness, genital impotence, sweat disturbances, sicca (dryness). Absence of signs of cerebellar dysfunction or parkinsonian symptoms as the presence of either would indicate the more serious disease of multiple system atrophy Ref Harrison20th edition pg 2568
