Brain Tumor - Glioblastoma

Signs and Symptoms

Signs and symptoms of glioblastoma depend on the size of the tumor and its location within the brain. Headaches are often an initial symptom caused by the pressure placed on the inside of the skull or on the brain's ventricular system. Nausea and vomiting are also common symptoms. Seizures occur in about one-quarter of patients with newly diagnosed glioblastoma and are usually controlled with anticonvulsant drugs throughout the course of the disease (Batash 2017; Alexander 2017; Reni 2017; DeAngelis 2012; NCCN 2016).

Tumors in some parts of the brain may cause weakness or numbness in the arms, legs, or face; loss of vision; or changes in speech. More subtle symptoms, such as cognitive dysfunction, mood disorders, personality changes, fatigue, and mild memory problems can also be observed in patients with larger tumors located in the frontal or temporal lobes, or in the corpus callosum, a structure that connects the two hemispheres of the brain (DeAngelis 2012; NCCN 2016; Alexander 2017; Batash 2017; Reni 2017).
