Treatment of Multiple System Atrophy with Nocturia and Nocturnal Micturition Syncope

This protocol targets patients with Multiple System Atrophy who present with nocturia — repeated nighttime urination — together with the risk of nocturnal micturition syncope, a dangerous episode of loss of consciousness that can occur when rising at night to void.

In this setting, nocturia is not only disruptive to sleep but directly elevates the risk of micturition syncope with each nighttime rise. Reducing the frequency of nighttime voiding and mitigating the syncope hazard are the two parallel goals addressed by this protocol.

First-line management involves timed modifications to evening fluid habits in the hours before sleep. Additional environmental measures to reduce syncope risk during nocturnal voiding are also part of the approach — including adaptations specifically relevant for male patients. The complete structured regimen is available below.
