Patients with NF-2 do not necessarily have the same characteristic skin symptoms (café-au-lait spots, freckling, and neurofibromas of the skin) that appear in NF-1. The characteristic symptoms of NF-2 are due to tumors along the acoustic nerve. Interfering with the function of this nerve results in the loss of hearing; and the tumor may spread to neighboring nervous system structures, causing weakness of the muscles of the face, headache, dizziness, poor balance, and uncoordinated walking. Cloudy areas on the lens of the eye (called cataracts) frequently develop at an unusually early age. As in NF-1, the chance of brain tumors developing is unusually high. Doctors have come up with ways to rank their importance to be able to make more reliable diagnoses. Patients may have “café-au-lait” spots which are darkened marks on the
