Which condition is categorized as affecting the quality of sleep by presenting physical and behavioral abnormalities?

Parasomnia is a category of sleep disorders that involve physical acts or behaviors that occur during sleep or sleep-wake transitions. This can include activities such as sleepwalking, night terrors, or abnormal movements. These behaviors can directly impact the quality of sleep by disrupting the person's ability to achieve restful slumber, leading to fragmented sleep patterns and reduced overall sleep quality.

In contrast, while sleep disorders as a broader category encompass a wide range of conditions that may affect sleep quality, parasomnia specifically highlights the physical and behavioral manifestations that are characteristic of this disruption. Chronic Fatigue Syndrome primarily refers to pervasive fatigue that is not explained by underlying medical conditions and is more focused on post-exertional malaise rather than direct sleep abnormalities. Panic Disorder, although it can affect sleep due to anxiety and related symptoms, does not inherently involve the sleep-related behaviors seen in parasomnias. Thus, parasomnia stands out as the condition that distinctly includes the physical and behavioral abnormalities affecting sleep quality.
