Tardive dyskinesia (TD) is a group of delayed-onset iatrogenic movement disorders caused by dopamine receptor-blocking medications that can manifest as orobuccolingual stereotypy, dystonia, akathisia, tics, tremor, chorea, or as a combination of different involuntary movements. Abnormal movements can persist for years despite discontinuation of the offending drug. In many cases, TD can be an irreversible condition, resistant to pharmacological treatment.

Diabetic neuropathies include a variety of disorders that afflict diabetics fairly exclusively and are characterized by variable degrees of peripheral nerve damage. Although chronic distal sensorimotor polyneuropathy is the most common type of diabetic neuropathy, other generalized and focal acute and chronic diabetic neuropathies are not uncommonly encountered in neurologic clinical practice.

Neuralgic amyotrophy is a disorder of the peripheral nervous system characterized by severe and sudden-onset forequarter region pain and forequarter muscle weakness and wasting. Although most neuralgic amyotrophy patients only experience a single event, multiple bouts (ie, recurrences) occur in approximately 12% of patients. They may involve the same limb or the contralateral limb, and they may involve the same nerves or have a different distribution of nerve involvement.

Acute disseminated encephalomyelitis (ADEM) is an inflammatory demyelinating disorder predominantly affecting white and gray matter in the brain and spinal cord. Clinical presentation includes encephalopathy (which may manifest as behavioral change, profound irritability, or altered consciousness) that cannot be explained by fever and polyfocal neurologic deficits. Systemic symptoms such as fever, headache, and fatigue often precede the development of neurologic deficits.
