Brief Summary: Conventional psychotropic medications may be used to treat behavioral disturbances and psychotic symptoms in patients with dementia and they are the drugs of choice for treating delusions and hallucinations However the sensitivity to side effects in these patients often restricts the use of these agents 2 3 Although atypical antipsychotics have some advantages compared with conventional neuroleptics they also are associated with side effects 5 6

Cholinesterase inhibitors ChEIs enhance neuronal transmission by increasing the availability of acetylcholine in muscarinic and nicotinic receptors According to findings of some researchers ChEIs have psychotropic effects and may play an important role in controlling neuropsychiatric and behavioral disturbances in patients with Alzheimers disease 7-10 These agents may also contribute to the management of other disorders with cholinergic system abnormalities and neuropsychiatric symptoms such as visual hallucinations 11

Donepezil is a piperidine-based reversible noncompetitive ChEI which is indicated in the management of patients with Alzheimers disease of mild to moderate severity 12-14 Preliminary observations suggest the possible value of ChEIs in the amelioration of psychotic symptoms in patients with dementia of the Alzheimers type DAT dementia with Lewy bodies and patients suffering from Parkinsons disease 11-18

The results of our study 18 indicate that the addition of donepezil to perphenazine resulted in qualitatively superior clinical gains compared to higher doses of neuroleptic therapy without donepezil

The finding of the pilot study although impressive stem from data regarding a rather small sample The present second phase of the study will include a larger sample of patients We now intend to examine 80 inpatients aged 65-90 years old suffering from DAT
Detailed Description: Criteria for inclusion into the study will be 1 DSM-IV diagnosis of Dementia of the Alzheimer type with psychotic symptoms such as hallucinations and delusions aggressionagitation irritability and disinhibition that called for the administration of antipsychotic drugs 2 duration of psychotic symptoms at least 2 weeks before beginning of treatment 3 lack of improvement of psychotic symptoms less than 25 on Positive and Negative Symptoms Scale PANSS during perphenazine treatment 8 mgday for at least three weeks 4 drug regimen for physical disease of all patients was unchanged for at least three months before the study

Exclusion criteria include 1 a vascular dementia 2 concurrent Axis I DSM-IV diagnoses delirium schizophrenia delusional disorders and affective disorders 3 significant medical illness cardiovascular liver renal endocrinal vitamin B12 or folic acid deficiency and neurological illnesses 4 drug orand alcohol addiction

The study design will be a double blind group study lasting for 9 weeks Complete physical and laboratory examinations will be performed on all inpatients Subjects will be randomized in a 11 fashion to receive treatment with 4 mg of perphenazine or 5 mg of donepezil or placebo in addition to the perphenazine treatment 8 mgday that they have received for the past 3 weeks baseline According to mental state improvement less than 20 on PANSS scores perphenazine dose will be elevated by 4 mgday to maximum 16 mgday in the first group and donepezil dose will be increased by 5 mgday to maximum 10 mgday in the second group and placebo will be elevated up to 2 capsulesday in the third group All preparations will be administered in identical capsules made by a professional pharmacist and supplied in individual number-coded packages

Assessments for psychotic symptoms will be done using PANSS and CGI at baseline and repeated weekly Assessments for extrapyramidal side effects will be done using AIMS at baseline and repeated every week In addition both at the beginning and at the end of the study all patients will be assessed with MMSE and GDS Complete blood profiles and urine analysis will be performed at screening and at week 9
