A significant number of brain tumor patients who received radiation or chemotherapy have thinking problems as a result of their treatment. The purpose of this study is to find out if treatment with Aricept (donepezil) may improve some aspects of thinking abilities in patients with brain tumors who received radiation or chemotherapy. This research will also study whether persons having particular genes for a blood-borne substance called apolipoprotein E (APOE) are more likely to have thinking problems after radiation or chemotherapy treatment for their brain tumors. The findings of this study will help us find out whether Aricept can improve thinking abilities after cancer treatment, and whether some of the thinking difficulties may be in part related to having certain genes.
A significant proportion of brain tumor patients treated with radiation or chemotherapy who are in disease remission experience cognitive sequelae from their treatment. Cognitive dysfunction can be of sufficient severity to interfere with their ability to function at premorbid professional and social levels. There are, however, no approved pharmacological interventions for improving cognitive functions in cancer patients who display treatment-related cognitive deficits. Donepezil, an acetylcholinesterase inhibitor, has been shown to provide cognitive and functional benefits in patients with Alzheimer's disease, vascular dementia, and in patients with other neurological diseases without known cholinergic deficiency. The proposed pilot study will examine the efficacy of donepezil in improving cognitive functions in adult brain tumor patients treated with radiation and/or chemotherapy who have mild to moderate cognitive difficulties. Neuropsychological measures of executive, psychomotor speed, attention, and memory abilities will be administered prior to, during and following donepezil therapy. The proposed study will also test the hypothesis that the apolipoprotein E (APOE) e-4 allele correlates with the development of cognitive impairment after radiation or chemotherapy treatments. The proposed investigation is unprecedented and may provide preliminary information about (1) a pharmacological therapy that could improve cognitive functions in this population, and (2) a genetic risk factor that may increase vulnerability to radiation or chemotherapy-induced cognitive decline.

RATIONALE: Donepezil and EGb761 may be effective in improving neurocognitive function (such as thinking, attention, concentration, and memory) and may improve quality of life in patients w...
RATIONALE: Donepezil may decrease the side effects caused by radiation therapy to the brain. PURPOSE: This clinical trial is studying how well donepezil works in treating young patients w...
The purpose of the study is to examine patterns of brain activity in people who are at risk for memory problems (e.g., Alzheimer's disease or dementia)before and after the medication donep...
This study investigate the relationship between regional brain volume measured by MRI and donepezil treatment response in patients with Alzheimer's Disease.
The study hypothesizes that donepezil will have a positive impact on brain blood flow deficits in subjects with memory deficits and/or mild dementia and that improvements in brain blood fl...
A few studies have performed on the brain morphometric changes over the whole brain structure following donepezil treatment in patients with Alzheimer's disease (AD). We evaluated the gray matter (GM)...
Donepezil is an established treatment for mild, moderate, and severe Alzheimer's disease (AD). An international study demonstrated superior efficacy of sustained release (SR) 23 mg/day donepezil ove...
Neoplasms of the brain are often overlooked in resource-limited countries. Our literature search via AJOL and PubMed demonstrated that brain tumor research is still a rarity in these regions. We highl...

Very few studies have utilized specific criteria to assess mental disorders in brain tumor patients, and from them, they are mainly descriptive. The purpose of this study is to examine mental disorder...
Tissue NECROSIS in any area of the brain, including the CEREBRAL HEMISPHERES, the CEREBELLUM, and the BRAIN STEM. Brain infarction is the result of a cascade of events initiated by inadequate blood flow through the brain that is followed by HYPOXIA and HYPOGLYCEMIA in brain tissue. Damage may be temporary, permanent, selective or pan-necrosis.
Localized reduction of blood flow to brain tissue due to arterial obstruction or systemic hypoperfusion. This frequently occurs in conjunction with brain hypoxia (HYPOXIA, BRAIN). Prolonged ischemia is associated with BRAIN INFARCTION.
Antineoplastic agent especially effective against malignant brain tumors. The resistance which brain tumor cells acquire to the initial effectiveness of this drug can be partially overcome by the simultaneous use of membrane-modifying agents such as reserpine, calcium antagonists such as nicardipine or verapamil, or the calmodulin inhibitor, trifluoperazine. The drug has also been used in combination with other antineoplastic agents or with radiotherapy for the treatment of various neoplasms.
Multi-channel hearing devices typically used for patients who have tumors on the COCHLEAR NERVE and are unable to benefit from COCHLEAR IMPLANTS after tumor surgery that severs the cochlear nerve. The device electrically stimulates the nerves of cochlea nucleus in the BRAIN STEM rather than the inner ear as in cochlear implants.
Bleeding within the brain as a result of penetrating and nonpenetrating CRANIOCEREBRAL TRAUMA. Traumatically induced hemorrhages may occur in any area of the brain, including the CEREBRUM; BRAIN STEM (see BRAIN STEM HEMORRHAGE, TRAUMATIC); and CEREBELLUM.
Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
