ACHE and Cognitive impairment: CEF and selegiline improved scopolamine induced cognitive impairment.  Both drugs (CEF and selegiline) showed a substantial memory enhancing ability compared to negative control.  Elevated level of acetylcholine esterase (AchE) were attenuated in mice that received either CEF or selegiline.  CEF or selegiline received mice also showed improved oxidative status.  Concomitant administration of CEF and selegiline displayed a synergistic action on cognitive-improvement, AchE and antioxidant activities.
