What Are Neuronal and Mixed Neuronal-Glial Tumors?

Neuronal and mixed neuronal-glial tumors are rare growths that form in the brain or spinal cord. These tumors affect the central nervous system, which controls movement, thinking, sensation, and many body functions.

The exact cause of these tumors is not fully known. Researchers continue to study possible genetic changes and other factors that may play a role. These tumors can occur in both children and adults.

Symptoms

Symptoms can vary depending on where the tumor develops and how large it becomes. Some people notice symptoms gradually, while others develop problems more suddenly.

Common symptoms may include:

• Seizures
• Headaches
• Nausea or vomiting
• Dizziness
• Problems with balance or coordination
• Difficulty walking
• Vision changes
• Trouble thinking clearly or memory changes
• Personality or behavior changes
• Increased sleepiness or fatigue

How Is It Diagnosed?

Healthcare providers begin with a detailed medical history and neurological exam. During the exam, they may test reflexes, coordination, strength, balance, and memory.

Imaging tests are often used to look closely at the brain and spinal cord. These may include:

• MRI scans
• CT scans

In many cases, a biopsy or surgery is needed to confirm the exact tumor type and determine how quickly it may grow.

How Is It Treated?

Treatment depends on the tumor’s size, location, and growth pattern. Surgery is often the first treatment and may successfully remove the tumor completely.

Other treatments may include:

• Radiation therapy
• Chemotherapy
• Medicines to help control seizures or symptoms

Some tumors require ongoing monitoring with regular imaging tests after treatment. Recovery varies from person to person, but many people with low-grade tumors do well after surgery and continued follow-up care.
