Based on the symptoms you've described, there are several potential nerve-related diseases that could cause these symptoms. One possibility is multiple sclerosis (MS), a chronic autoimmune disease that affects the central nervous system. However, it is important to remember that I am an AI language model and cannot provide a diagnosis. It is best to consult a medical professional for an accurate evaluation.

To diagnose the specific disease causing these symptoms, a healthcare provider may perform a series of examinations, including a physical examination, neurological examination, and possibly further tests such as magnetic resonance imaging (MRI) or a lumbar puncture. These tests can help identify any abnormalities or inflammation in the brain, spinal cord, or optic nerves, which can aid in arriving at a diagnosis.

If you or someone you know is experiencing these symptoms, it is important to seek medical attention promptly to receive the appropriate care and diagnosis.
