Affected Individuals
Shy-Drager syndrome has an equal impact on both males and females. While the majority of individuals develop the disease between the ages of 55 and 60, it has been known to affect people as young as 30 and as old as 90. Recent studies estimate that approximately 1,900 new cases of this syndrome are diagnosed each year in the United States. Interestingly, when compared to similar diseases, there is one living case of multiple system atrophy for every 40 cases of Parkinson’s disease. This statistic is particularly relevant because individuals with Parkinson’s disease generally have a longer life expectancy compared to those with multiple system atrophy.
Diagnosis of Shy-Drager Syndrome
Diagnosing Shy-Drager syndrome can be challenging for doctors as it shares similarities with Parkinson’s disease. However, several tests and assessments can help differentiate between the two conditions.
One method of diagnosis is through the use of magnetic resonance imaging (MRI), which can reveal changes in different areas of the brain. Another test, known as a tilt table test, can confirm the presence of orthostatic hypotension, a common symptom of Shy-Drager syndrome.
Various other tests can also aid in detecting autonomic dysfunction, a key feature of the syndrome. These include blood tests, sweat tests, electrocardiograms (ECGs), and bladder assessments. Additionally, some doctors may choose to evaluate patients in a sleep laboratory to identify any abnormalities in sleep patterns.
