Many of the symptoms of<unk>  overlap with NF2. * Schwannomas occur instead of the neurofibromas that are hallmarks of neurofibromatosis Type 1 (NF1). * Multiple schwannomas manifest throughout the body or in isolated regions. * The schwannomas develop on cranial, spinal and peripheral nerves. * Chronic pain, and sometimes numbness, tingling and weakness. * About 1/3 of patients have segmental<unk> , which means that the schwannomas are limited to a single part of the body, such as an arm, a leg or the spine. * There are several cases where people with<unk>  have developed a vestibular schwannoma (acoustic neuroma). An acoustic neuroma is a schwannoma on the vestibular nerve in the brain. This nerve is involved in hearing and patients with vestibular schwannomas experience hearing loss. However, bilateral vestibular schwannomas (vestibular schwannomas on both sides of the brain) do not occur in<unk> . Juvenile vestibular tumors do not occur either. * Patients with<unk>  do not have learning disabilities related to the disease. * Symptoms are sometimes brought on by hormonal changes such as puberty and pregnancy.
