• Self-reported cognitive disruption (FACT-Cog Version 3 Perceived Cognitive Impairments sub-score of < 63)

• Negative serum pregnancy test within 10 days prior to registration for women of child-bearing potential.

EXCLUSION CRITERIA:

• Evidence or suspected recurrent or metastatic disease

• History of dementia, Alzheimer's disease, multi-infarct dementia or CVA (history of transient ischemic attack (TIA is allowed)

• Current use of donepezil, galantamine, rivastigmine, tacrine, memantine, methylphenidate, dextroamphetamine, or any other specific cognition enhancing drugs.are not allowed. For patients who have used these medications they must not have used them within 4 weeks prior to registration.

• History of schizophrenia, psychosis or substance abuse

• Untreated current severe depression. (Currently treated depression is permitted if treatment is stable.)

• Acute severe fatigue, chronic fatigue syndrome or fibromyalgia.

• History of hepatic or renal dysfunction or disease

• Pregnant women are excluded from this study. The effects of donepezil on the developing human fetus at the recommended therapeutic dose are unknown. For this reason and because donepezil is known to be teratogenic, women of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her study physician immediately.

• It is unknown whether donepezil is excreted in breast milk, for this reason women who are currently breast-feeding are not eligible for this study.
