Fatigue

What it is

Fatigue is a profound, persistent tiredness — more than ordinary tiredness and not fully relieved by rest — that is very common in people with gliomas and during their treatment. It can significantly affect daily life and quality of life.

Understanding Fatigue

Fatigue is one of the most common and underappreciated symptoms in people with gliomas. It can stem from many sources: the tumor itself and its effects on the brain, treatments (radiation and chemotherapy commonly cause fatigue), medications (such as anti-seizure drugs or steroids), disrupted sleep, emotional factors (such as anxiety or low mood), and other contributors (such as anemia). Glioma-related fatigue is often described as overwhelming and is more than feeling sleepy — it can include mental fatigue and reduced motivation. Because it has multiple causes, managing fatigue involves addressing contributing factors (such as adjusting medications, improving sleep, treating low mood or anemia), balancing activity and rest, gentle exercise where appropriate, and support. Recognizing fatigue as a real, manageable symptom — not a personal failing — is important. Understanding fatigue in gliomas clarifies a common, impactful, but addressable symptom.

Why it matters

Understanding fatigue helps patients and families recognize profound tiredness as a real and common effect of a glioma and its treatment — not a personal failing — that has multiple causes and can be managed and supported.
