Progressive supranuclear palsy (PSP) is a late-onset degenerative disease of the CNS characterized by balance difficulties, vertical gaze palsy, dysarthria, dysphagia, and axial dystonia. Many patients also present with complaints of cognitive slowing, apathy, loss of verbal fluency, and loss of ability to recognize emotion in others. Patients with PSP are more likely to progress faster if they have poorer baseline performance on cognitive tests.

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.

The brachial plexus is a network of nerves that control the shoulder, arm, and hand. A brachial plexus injury occurs when these nerves are stretched, compressed, or in the most serious cases, ripped apart or torn away from the spinal cord. Mechanism of injury, time since injury, type of injury (preganglionic or postganglionic), and associated injuries are all important factors to consider when determining a treatment option.
