Thalamic and midbrain infarcts are infrequent; however, both are associated with a large spectrum of clinical manifestations. Decreased level of consciousness, vertical gaze paresis, and contralateral hypoesthesia are the main clinical manifestations of paramedian thalamic infarcts. Oculomotor and supranuclear vertical gaze palsies are the most localizing manifestations of midbrain infarction. In general, the neurologic status improves over time.

Limb girdle muscular dystrophy (LGMD) is a genetically inherited condition that primarily affects skeletal muscle leading to progressive, predominantly proximal muscle weakness at presentation caused by a loss of muscle fibers. To be considered a form of LGMD the condition must be described in at least 2 unrelated families with affected individuals achieving independent walking, must have an elevated serum creatine kinase activity, must demonstrate degenerative changes on muscle imaging over the course of the disease, and have dystrophic changes on muscle histology, ultimately leading to end-stage pathology for the most affected muscles.

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.
