Title: Effect of Indomethacin on the Progression of Alzheimer's Disease
Brief Summary: The purpose of this study is determine whether indomethacin is able to retard disease progression in patients with mild to moderate Alzheimer's disease.


Options:
A: Inclusion Criteria:

* The patient will satisfy the DSM-IV criteria for dementia of the Alzheimer's type.
* The patient will satisfy the NINCDS/ADRDA criteria for the clinical diagnosis of probable Alzheimer's disease (Appendix I).
* The severity of dementia for each patient will be quantified by a Mini-Mental State Examination (MMSE) score between 10 and 26 (both inclusive).
* The patient is living at home or in a home for the elderly.
* The patient has a responsible caregiver who is able to provide information about the patient's functional status.
* Written informed consent is obtained from the patient or the legally accepted representative.

Exclusion Criteria:

* The patient satisfies the NINDS-AIREN criteria for probable vascular dementia.
* A known exaggerated pharmacological sensitivity or allergy to NSAID's.
* History of peptic ulceration, gastric surgery or gastrointestinal bleeding.
* Current diagnosis of active peptic ulceration.
* Current diagnosis of severe and unstable cardiovascular disease.
* Current diagnosis of renal failure.
* Advanced, severe and unstable disease of any type, other than Alzheimer's disease, that may interfere with primary and secondary variable evaluations, including a medical condition which should be expected to progress, recur, or change to such an extent that it may bias the assessment of the clinical or mental status of the patient to a significant degree or put the patient at special risk.
* Intake of any of the following concomitant medications: salicylates, coumarin derivatives, ACE-inhibitors, loop diuretics.
* Intake of any of the following concomitant medications more than two months immediately prior or during the study: NSAID's, systemic corticosteroids.
* Intake of any of the following concomitant medications with a possible effect on cognition: estrogen, deprenyl, vitamin E, neuroleptics, anticholinergics. Patients using stable doses of cholinesterase inhibitors were eligible, with the provision that the dose should not be changed during the study. Cholinesterase inhibitors could not be initiated during the study.
* Excessive use of alcohol (more than 5 units per day)
* The patient is, either alone or with the aid of a caregiver, not able to reliably take the medication.
B: * INCLUSION CRITERIA:

To be eligible for the study each participant must have at least one eye, which satisfies all ocular inclusion criteria:

1. Participants with type 1 or 2 diabetes.
2. Participants with clinically significant macular edema in at least one eye that requires laser treatment, but in the opinion of the Investigator, can be delayed for up to at least 3 months.
3. Best corrected visual acuity 20/400 or better as measured on an ETDRS chart in the eye with clinically significant macular edema; this eye will be considered they study eye. If both eyes have clinically significant macular edema and best corrected visual acuity greater than or equal to 20/400, the right eye will be considered the study eye, however, both eyes will be eligible for treatment.
4. May have had proliferative diabetic retinopathy but scatter photocoagulation must have been performed more than four months ago.
5. Ocular media sufficiently clear to allow for quality fundus photography.
6. If aphakic or pseudophakic, lens removal must have occurred at least 6 months prior to enrollment.
7. Documented hemoglobin A1C 12% or less within one month of baseline.
8. Willingness to accept randomization for diet or drug therapy for lowering of elevated lipid levels (for sites participating in the Lipid Lowering study option).
9. Understand and sign the informed consent.
10. Participants 18 years of age and older since the population of interest is primarily adults.

EXCLUSION CRITERIA:

To be eligible for the study, each participant must not satisfy an ocular exclusion cirterion in both eyes.

1. Retinopathy that requires scatter photocoagulation immediately.
2. Ocular disease other than diabetic retinopathy that may confound the outcome of the study (e.g. age-related macular degeneration, drug toxicity, uveitis, etc.).
3. Prior of current macular detachment in the eligible eye(s).
4. Use of an investigational drug within 30 days of enrollment.
5. Malaborsorption syndrome.
6. Concurrent administration of the anti-obesity drug orlistat (Xenical).
7. Positive serum pregnancy test or currently lactating for women of childbearing potential.
8. Chronic requirement (e.g., greater than or equal to 4 weeks at a time) for ocular medication for diseases that, in the judgement of the examining physician, are vision thereateniong or may affect the primary outcome (artificial tears are permitted).
9. History of cancer and prognosis of survival of less than 3 years.
10. Participants whose diabetic macular edema, in the opinion of the Principal Investigator, cannot benefit from laser treatments, including those with subretinal fibrosis, severe macular non-perfusion, or parafoveal leakage in oth eyes.
11. Participants that have a history of focal laser treatment, and in the opinion of the investigator are thought to be refractory (e.g., \> 50 micron burns or equivalent) to laser treatment or wwere treated within 3 months of baseline.
12. Participants with clear vireal-retinal tracion wiich in the opinion of the investigator needs to be treated as a contributor macular edema.
13. Participants requiriing herapy with topaical ophthalmic prostaglandin analogues.
14. Laboratory values outside normal limits and considered clinically significant by the investigator.
15. Past or current liver disease, which precludes the use of the lipid-lowering drugs.
16. Used Celebrex \[Registered Trademark\] or any other COX-2 inhibitor, NSAIDs, or ocular topical NSAID use great than 3 days per week for a period of 4 weeks or more within 6 months prior to enrollment, or likely need during the study (Aspirin dose of 325 mg per day is permitted).
17. Concurrent warfarin therapy or known bleeding diathesis.
18. Concurrent lithium therapy.
19. History of peptic ulcer disease within 1 year prior to enrollment.
20. History of kidney disease (serum creatinine greater than 2.5 mg/dL, or need for dialysis).
21. Allergy to sulfa- containing compounds, NSAIDs, or demonstrtion of the aspirin triad.
22. History of inflammatory bowel disease.

* The subject is willing to abstain from chronic use of all NSAIDs or COX-2 inhibitors excluding aspirin at cardioprotective doses for the duration of the study.
