Post-polio syndrome may result in which of the following conditions?

1. Memory loss

2. Sleep apnea

3. Depression

4. Increased muscle strength

The correct answer is: Sleep apnea

Post-polio syndrome is a condition that affects polio survivors, typically many years after recovery from the initial polio infection. It is characterized by new or worsening muscle weakness, fatigue, and pain. Among the symptoms that may arise from post-polio syndrome, sleep apnea is significant and relevant. Individuals with post-polio syndrome may experience sleep apnea as a result of respiratory muscle weakness or changes in the neuromuscular function that can arise from their previous poliovirus infection. This condition can lead to interrupted breathing during sleep, contributing to daytime fatigue and a decline in overall health status. In this context, while memory loss, depression, and increased muscle strength are not typically associated with post-polio syndrome in a direct manner, sleep apnea is a recognized complication that can greatly impact the quality of life for affected individuals. The presence of sleep apnea in these patients is noteworthy and underscores the importance of monitoring and managing the various dimensions of health that can be influenced by post-polio syndrome.
