Some common symptoms that may indicate a problem in the brain are nausea, vomiting, dizziness, trouble concentrating, memory lapses, numbness, and problems in speech. While these symptoms do occur in people with a brain disorder, they do not necessarily indicate a brain problem. It is best to consult a general physician if you are feeling any of these in order to understand the cause of the symptoms.
Depending on the symptoms and patient history, the most common tests that a neurosurgeon or neuro physician will prescribe to identify the root cause of neurological symptoms include an MRI, CT scan, PET scan, EEG, angiogram and lumbar puncture.
On your first visit, the neurologist will typically ask you detailed questions about your symptoms to understand the root cause. They will ask questions about the duration, intensity & frequency of your symptoms, any medical history or family history of neurological problems and ongoing medication.
