Patients with SDS will not have the normal increase in blood pressure and heart rate.
Medication can relieve many of the symptoms, especially the parkinsonism and low blood pressure.
Gastrostomy — An artificial opening into the stomach through the abdomen to enable a patient to be fed via a feeding tube.The procedure is given to patients with SDS who are unable to chew or swallow..In later stages, problems in the autonomic nervous system lead to breathing difficulties such as sleep apnea, loud breathing, and snoring.In advanced stages of the disease, patients can die from irregular heartbeat.Other drug treatment includes fludrocortisone, indomethacin, nonsteroidal anti-inflammatory drugs, beta blockers, central stimulants, and other medications.
Occasionally, a pacemaker, gastrostomy, or tracheostomy may be needed.
When this problem becomes severe (for example, a blood pressure below 70/40 mm Hg), it can lead to a momentary loss of consciousness.
When the person faints, the blood pressure returns to normal and the person wakes up.
Another test for the condition is the Valsalva maneuver.
In this test, the patient holds his or her breath and strains down as if having a bowel movement while the doctor monitors blood pressure and heart rate for 10 seconds.
However, typical antiparkinsonism drugs such as carbidopa-levodopa (Sinemet) should be used with caution, since they often worsen the postural low blood pressure and may cause fainting.
