Neuro-Ophthalmology & Neuro-Otology
Nystagmus refers to rhythmic involuntary oscillations of one or both eyes. Visual loss or ophthalmoparesis may be present. It may be physiologic or pathologic, and congenital or acquired.

Orbital pathology can result in neuro-ophthalmic manifestations such as optic neuropathy and ocular misalignment, leading to vision loss and diplopia. Proptosis is the hallmark of orbital pathology, but is not always present. Thyroid-related orbitopathy, orbital tumors, and orbital inflammatory syndromes are common orbital conditions.

Multiple sclerosis (MS) lesions in the brain and spinal cord damage every function of the central nervous system. Clinical symptoms vary from mild to aggressive; the course can be relapsing-remitting or progressive, and the symptoms and course evolve over time. Protean symptoms include fatigue and disturbed sensory, motor, bladder, bowel, sexual, cerebellar, brainstem, optic nerve, and cognitive realms.

Nerve ultrasound for neuropathy allows for the determination of peripheral nerve anatomical course, echogenicity, vascularity, and degree of mobility. Magnetic resonance neurography allows for visualization of higher soft-tissue contrast, which can depict milder abnormalities when there are subtle T2 signal abnormalities.

Headache & Pain
Orofacial and cephalic pain can arise from a variety of conditions that affect the nerves that supply the head, their roots, and other pain-sensitive structures. Trigeminal neuralgia, the prototypical cephalic neuralgia, is characterized by bursts of excruciating facial pain in the distribution of one or more branches of the trigeminal nerve. Cranial neuralgias may be secondary to central nervous system or peripheral pathology, including carotid artery dissection, arterial venous malformations, and aneurysmal dilatation with subsequent compression.

Nerve injury can range from minor and transient alteration in sensation to severe and permanent interruption of sensory and motor function, dependent on the particular nerve or nerves that have been injured, and the severity and level of the lesion. Pain and loss of sensory and motor function are usually noted either immediately or within days of the inciting event.
