The field of movement disorders is relatively broad, encompassing disorders of increased
movement, such as tremors, dystonia, and tics, to disorders characterized by a
paucity of movement, such as Parkinson’s disease. Our understanding of the pathogenic
mechanisms and our treatment options are expanding at a rapid pace. This expansion
ranges from the medical and surgical advances in treating Parkinson’s disease to the flood
of genetic abnormalities that have now been found to cause various movement disorders.
Evidence of left hemispatial neglect and simultanagnosia. A. A 47-yearold man with a large frontoparietal lesion in the right hemisphere was asked to circle all the As. Only targets on the right are circled. This is a manifestation of left hemispatial neglect. B. A 70-year-old woman with a 2-year history of degenerative dementia was able to circle most of the small targets but ignored the larger ones. This is a manifestation of simultanagnosia.Cerebrovascular lesions and neoplasms in the right hemisphere are the most common causes of hemispatial neglect.
While history and examination will always remain the foundation of neurolog-
ical diagnosis, MRI and CT have now become the most important diagnostic
tests used by neurologists and neurosurgeons. These tests are critical not only
for confirming clinical diagnosis, but in many cases will give additional infor-
mation absolutely essential to patient care. Modern clinical diagnosis and treat-
ment of central nervous system disorders relies heavily upon neuroimaging. In
some cases, the optimal management of clinical problems affecting patients
with brain tumors, strokes, etc.
