Eye-movement disorders in brain-stem and cerebellar stroke.

Vertebrobasilar strokes can yield varied disturbances of eye movements, by affecting specific centers and pathways contained in the brain stem and cerebellum. Unique disorders combining supranuclear, nuclear, and infranuclear syndromes may occur. Some eye-movement abnormalities are useful localizing signs (eg, gaze palsies, rotatory nystagmus, and ipsilateral saccadic bias), but many others are not. The use of techniques such as magnetic resonance imaging may provide new insights in clinicotopographic correlations in patients with good recovery, in the absence of pathologic verification.

Paroxysmal dyskinesias as a paradigm of paroxysmal movement disorders.

Paroxysmal dyskinesias are genetically and clinically heterogeneous. Paroxysmal kinesigenic choreoathetosis is frequently familial, with autosomal-dominant transmission. Benign infantile convulsions can be observed in these families and both diseases as linked to the pericentromeric region of chromosome 16. Two different forms of paroxysmal dystonic choreoathetosis are distinguished on clinical grounds, by the presence or absence of spasticity, and genetically, as they are linked with loci on different chromosomes. Among the paroxysmal disorders, these diseases may belong to the group of channelopathies.

Strategies underlying the control of disordered movement.

The purpose of this article is fourfold. First, a theory of motor control--the dual-strategy hypothesis--is outlined. Second, the methodologies and theoretical framework that are used to develop this theory are examined. Third, motor dysfunction is discussed in the context of this theory. In particular, Down syndrome, Parkinson's disease, cardiovascular accidents, and spasticity are discussed. Finally, potential applications of the theory to physical therapy are considered.
