Brain tumors can take many forms. Even those that aren’t cancerous can put pressure on delicate areas of the brain, causing symptoms. The symptoms you experience will depend on the type of tumor you have and where it’s located in the brain.
Tinnitus — or ringing in the ears — and dizziness can occur with some types of brain tumors, but these are usually indirect symptoms.
There are just a few millimeters of space between the brain and the skull. The adult brain — weighing about 3 pounds — along with the meninges and cerebrospinal fluid, uses just about every inch of space in the cranial cavity. Any growths, extra fluid, or any kind of swelling can cause serious problems.
The tissues of the brain are delicate and very sensitive to pressure. When tumors develop, parts of the brain can swell or become displaced, putting pressure on the other areas. This is called cerebral edema, and it can lead to increases in your intracranial pressure.
Symptoms of cerebral edema may include:
Any tumor, as well as a number of other injuries and infections, can cause increases in intracranial pressure and cerebral edema. In addition to symptoms caused by overall swelling, damage can also be caused to different parts of the brain from direct pressure or by the tumor.
One example of this is acoustic neuroma (vestibular schwannoma). This is a benign (noncancerous) tumor that develops on the eighth cranial nerve. Although this tumor is slow-growing and doesn’t spread to other parts of the brain or cause cancer, the nerve it develops on helps to control hearing and balance.
Tinnitus and dizziness aren’t the defining symptoms of this kind of tumor, but they’re commonly reported. In one study, 80 percent of people with acoustic neuromas reported hearing loss in one ear. The second most common symptom was tinnitus in one ear (6.3 percent), followed by dizziness, vertigo, and headaches.
Other types of growths, like skull base tumors, can also affect the parts of the brain that control balance and hearing.
Ringing ears and dizziness aren’t the only things that could signal a brain tumor. The brain is the command center for the entire body, so as different parts of the brain are affected, symptoms can appear in the different body systems they control.
Some common symptoms of brain tumors include:
- vision changes
- hearing loss
- changes to your sense of smell
- personality changes
- sleep problems
- memory problems
- balance problems
- weakness, especially on one side of the …….
