11. Visual field testing: Assessing peripheral vision to detect potential visual impairments caused by tumors.
12. Neuropsychological testing: Evaluating cognitive functions such as memory, attention, and language abilities.
13. Genetic testing: Screening for inherited genetic mutations associated with an increased risk of brain tumors.
14. Electromyography (EMG): Recording electrical activity in muscles to assess nerve function and detect any abnormalities.
15. Evoked potentials: Measuring electrical signals in response to sensory stimuli to assess nerve function.
16. X-ray: Providing images of the skull and spine to rule out other potential causes of symptoms.
17. Ophthalmological examination: Assessing visual acuity and eye movements to identify any abnormalities associated with brain tumors.
18. Endocrine testing: Checking hormone levels to detect any imbalances caused by pituitary tumors.
19. Neuroimaging with contrast: Injecting a contrast agent to enhance the visibility of tumors on MRI or CT scans.
20. Molecular profiling: Analyzing tumor tissue to identify specific genetic mutations or biomarkers that may guide treatment decisions.

Treatments for Deep Grey Matter Tumors:

Treatment options for deep grey matter tumors depend on various factors, including the type of tumor, its location, size, and the patient’s overall health. Non-pharmacological treatments may include:

1. Surgery: Removing the tumor to relieve pressure on surrounding brain tissue and reduce symptoms.
2. Radiation therapy: Using high-energy beams to target and destroy cancerous cells.
3. Chemotherapy: Administering drugs to kill cancer cells or inhibit their growth.
4. Targeted therapy: Using drugs or other substances to specifically target cancer cells while minimizing damage to healthy tissue.
5. Immunotherapy: Stimulating the body’s immune system to recognize and attack cancer cells.
6. Watchful waiting: Monitoring the tumor’s growth and progression without immediate intervention.
7. Stereotactic radiosurgery: Delivering precise doses of radiation to tumors while minimizing damage to surrounding tissue.
8. Laser interstitial thermal therapy (LITT): Using laser energy to heat and destroy tumor cells.
9. Brachytherapy: Placing radioactive sources directly into or near the tumor to deliver targeted radiation therapy.
10. Electrochemotherapy: Combining chemotherapy with electric pulses to enhance drug delivery to tumor cells.
11. Photodynamic therapy: Administering a photosensitizing agent followed by light therapy to destroy tumor cells.
