Management of Mild Cognitive Impairment Patients With Greek Mountain Tea - TEAMENTIA

Study Overview
=================
Brief Summary
-----------------
There is accumulating evidence suggesting that Greek Mountain Tea may have a positive impact on conditions involving cognitive deficits, such as Mild Cognitive Impairment (MCI) and AD. More specifically, greek mountain olympos tee is rich in essential oils, flavonoids, diterpenes and phenylpropanes, which are primarily responsible for its pharmacological properties. Its confirmed antioxidant properties are what make mountain tea promising against Alzheimer's disease and other neurodegenerative diseases. It has also been proven to possess cholinergic and cognitive enhancing capabilities. Greek Mountain Tea is deeper studied and it shows promising results in neuroprotection against AD through various suggested mechanisms, such as the enhancement of amyloid-beta clearance in the brain and the inhibition of neurofibrillary tangles formation. The aim of the study is to evaluate the beneficial effect of Greek Mountain Tea in patients diagnosed with mild cognitive impairment MCI. Study Type: Interventional Study Design: Allocation: Randomized Intervention Model: Parallel Assignment Masking: Double Blind (Subject, Investigator) Primary Purpose: Prevention

Detailed Description
-----------------
OBJECTIVES OF THE TRIAL The objectives of this study are: To investigate the efficacy of Greek Mountain Tea as a disease course modifying treatment for MCI in a phase III double-blind placebo-controlled study. To investigate the effects in objective measurements in patients with MCI. STUDY DESIGN This is a Greek, randomised, double-blind, placebo-controlled study group of compared Greek Mountain Tea placebo. Qualifying patients will be randomly assigned to receive 12 grams of Greek Mountain Tea or mediterranean dietary protocol on a daily basis for 24 months. Patients undergo assessments at baseline,12 and 24 months +/- 7 days after beginning of the treatment. Duration The total study duration will be 36 months. Patients will receive study medication for 24 months.The recruitment will be about 6 months and the statistics and the preparation of the paper other 6 months. Number of Subjects One hundred fifty (100) subjects total will be enrolled. ; Fifty (50) in the experimental group (Greek Mountain Tea); and Fifty (50) in control Group 2(same dietary habits mediterranean dietary protocol). Patient Eligibility Screening Form (ESF) An eligibility form documenting the patient's fulfilment of the entry criteria will be completed by the assessor. The following information will be included in the ESF: Patient identification: Initials (First initial of first name and First initial of surname), date of birth and Patient Identification Number. Eligibility Screening; Checklist of inclusion and exclusion criteria Eligibility Statement; for patients found to be ineligible, the reason for ineligibility must be stated Written informed consent will be obtained from the subject . The informed consent form must be co-signed by the physician. The nature of the study and the potential risks associated with the trial will be explained to all subject candidates and their responsible informants. Signature and date: the ESF may be completed by an assessor but it is required that the principal investigator/study clinician sign and date the ESF to verify eligibility of the patient for inclusion.
