A 40-year-old male complains of uncontrolled excessive movement and progressive dysfunction of intellectual and thought processes. He is experiencing movement problems that begin in the face and arms and eventually affect the entire body. The most likely diagnosis is:

Alterations in cognitive systems, cerebral hemodynamics, and motor function can cause problems and diseases that affect functional adequacy.  Some examples of alterations in cognitive systems include: Alterations in arousal, Alterations in awareness, Data processing deficits, and Seizure disorders.  Some examples of alterations in cerebral hemodynamics include: Abnormalities in the control mechanisms regulating cerebral blood flow, Disorders of cerebral metabolism  Some examples of alterations in motor function include: Alterations in muscle tone, Alterations in movement, and...

Alterations in cognitive systems, cerebral hemodynamics, and motor function can cause problems and diseases that affect functional adequacy. 

Some examples of alterations in cognitive systems include: Alterations in arousal, Alterations in awareness, Data processing deficits, and Seizure disorders. 
Some examples of alterations in cerebral hemodynamics include: Abnormalities in the control mechanisms regulating cerebral blood flow, Disorders of cerebral metabolism 

Some examples of alterations in motor function include: Alterations in muscle tone, Alterations in movement, and Extrapyramidal motor syndromes. 
Periventricular vascular lesions can cause simultaneous dysfunction in both motor and cognitive systems. This is due to the close proximity of frontal-subcortical circuits that control both systems.
