ENG question

[Jennifer Lantz, MS, CFY/A]

I am going to post this on here first and maybe on asha-forum. Does 
anyone know if hyperactive optokinetic responses (not OKAN)is indicative 
of a central problem. For a 20 deg target the responses were approx. 50 
deg (symmetrical) and for a 30 deg target they were about 70 deg 
(symmetrical). I can find references to hyperactive OKAN but not OKN. 
The sources only mention hypoactive responses for OKN. Thanks in 
advance.
