Headaches (recurrent or constant), nausea, vomiting, decreased appetite, changes in mood, changes in personality, behavioral changes, cognitive decline, inability to concentrate, vision problems, hearing problems, and balance problems are all common symptoms in patients with various types of brain lesions. A patient with a brain tumor may experience any or all of these symptoms. The location where the tumor is growing affects which parts of the body it can be felt in. For example, if a tumor is growing in the frontal lobe, it may cause headaches, dizziness, and problems with decision-making. It may also cause nausea and vomiting. The patient may also have visual problems such as double vision or loss of vision in that eye movement control is affected by this type of lesion. Hearing problems may occur if the tumor impacts the auditory cortex. Problems with balance may occur if the nerve connecting the cerebellum and the brainstem is damaged. Symptoms will vary depending on the type of brain tumor. For example, patients with gliomas may experience headaches, mental changes, nausea, vomiting, and weakness. Patients with meningiomas may experience headache, depression, anxiety, memory problems, speech difficulties, pain, numbness, tingling, or blindness. Brain tumors are usually diagnosed using magnetic resonance imaging (MRI) or computerized axial tomography (CT) scans.
