10 Reye's Syndrome Symptoms
Reviewed: Dr. Gromatzky
Symptom #5: Lethargy
Lethargy is different from simple sleepiness in that it is a deep-seated form of fatigue. Patients with lethargy are often unable to perform simple tasks and find that it’s hard for them to follow a daily routine.
Lethargy can be both an initial symptom and one that persists throughout the development of the condition. Some children and teenagers experience lethargy, daytime sleepiness, and vomiting that fade, whereas others don’t develop lethargy until the condition has progressed.
