Neurofibromatosis 2 is a tumor predisposition syndrome most commonly associated with the development of multiple schwannomas (classically bilateral vestibular schwannomas), meningiomas, and ependymomas. Most adult patients present with symptoms of hearing loss, tinnitus, and impaired balance. Children more commonly present with visual symptoms such as strabismus, cataract, visual loss, or proptosis, and sometimes unilateral facial nerve paralysis or seizures.

Transverse myelitis is part of a spectrum of demyelinating disease but has unique features that differentiate it from multiple sclerosis. The spinal cord damage in acute complete transverse myelitis generally affects all cord functions, and the symptoms are typically more severe than in typical cord lesions of multiple sclerosis. The first symptoms in transverse myelitis are ascending paresthesias or back pain at the level of the myelitis, plus leg weakness and sphincter dysfunction. Tingling or paresthesias in the feet soon progress to loss of pain, temperature, and vibration sensation, and then halt at a sensory level, usually thoracic (approximately 80%).

Amyotrophic lateral sclerosis (ALS), also known as motor neuron disease (MND), is a neurodegenerative disease that causes progressive muscle weakness and fasciculations without sensory loss. Presenting symptoms can be bulbar, cervical, thoracic, or lumbosacral.

Headache & Pain
Chronic pain can be considered a neurologic disorder by itself and is also a symptom of several neurologic diseases, such as Parkinson disease. It manifests by several sensations, such as stabbing and burning, and is usually triggered by noxious stimuli or by lesions in the nervous system. Prognosis and complications are determined by the primary condition causing pain and condition of the patient.
Epilepsy & Seizures
Epilepsy with continuous spike-and-waves during sleep syndrome can be characterized by the following features: (1) epilepsy, with focal and apparently generalized seizures; (2) neuropsychological impairment with global or selective regression of cognitive functions; (3) transient motor impairment with ataxia, dyspraxia, dystonia, or unilateral deficits; (4) typical EEG findings with diffuse or more or less unilateral electrical status epilepticus during slow sleep occurring in up to 85% of slow sleep.
