There are many other symptoms that might lead your doctor to refer you to a neurologist. These are generally unexplained symptoms that could be caused by several conditions. For example, unexplained pain could be the result of multiple conditions that cause your nerves to become overactive, while dizziness could be the result of injury or inflammation to your brain. Memory loss can also lead people to a neurologist. You might be referred if you’ve been having increased forgetfulness, trouble concentrating, and brain fog.
