Symptoms & Diagnosis (DX)

Brain Map


While there are many types of symptoms to Glioblastoma and Astrocytoma (a lower grade of Glioblastoma), below is a list. These symptoms can and will depend on the location of the tumor. Below is a list of common signs:

  • Headache
  • Nausea or vomiting
  • Dizziness or vertigo
  • Confusion or decline in brain function, trouble thinking, gradual loss of fine motor skills
  • Memory loss
  • Personality changes or irritability, mood changes
  • Difficulty with balance
  • Urinary incontinence
  • Vision problems such as blurred vision, double vision or loss of peripheral vision
  • Speech difficulties, trouble speaking, making complete sentences
  • Seizures, especially in someone without a history
  • Weakness on one side of the body




Diagnosis of Glioblastoma Multiform and brain tumors is done is done by utilizing MRI’s, CAT Scans, blood test, lumbar puncture and a biopsy of the growth. Doctors may use a neurological exam to diagnose low grade gliomas.

  • Functional MRI: Maps brain activity by valuating the structures of the brain and detecting changes in blood flow
  • Perfusion MRI: Identifies parts of the brain with less blood flow, a potential sign of a tumor blocking the path
  • Tractography: Visualizes white matter tracts which carry electric signals and sensory information for the central nervous system. These images are uploaded to a neurosurgical navigation system in the operating room to guide the surgeon around critical pathways as the tumor is removed.
  • CT Scan to diagnose astrocytomas – some people cannot have an MRI because the magnet interfere with implanted medical devices such as pacemakers etc. CT scans take multiple x-rays and provide doctors with another way to see structures in the brain.
  • Biopsy – A biopsy removes cells (not the tumor) from the tumor. Doctors can confirm the sample is cancerous based on the information and pathology which can also determine how aggressive.
