Health condition and Intervention

Section to complete information about the primary medical condition(s) or problem(s) studied and, a characteristics of the intervention(s).

Health condition(s) or Problem(s) studied:

Mild Cognitive Impairment and Mild Alzheimer's Dementia

Intervention(s):

Patients with Mild Cognitive Impairment Deprexil Group (Experimental): Deprexil + Cognitive stimulation. Deprexil will be administered one vial (30 ml) Deprexil® oral solution every 12 hours (given after breakfast and lunch) for 6 months Placebo Group (Control): Placebo + Cognitive stimulation. The placebo will be administered in the same way and with the same frequency and duration as Deprexil. Patients with Mild Alzheimer's Dementia Deprexil Group (Experimental): Deprexil + Cognitive stimulation. Deprexil will be administered one vial (30 ml) Deprexil® oral solution every 12 hours (given after breakfast and lunch) for 6 months. In addition, they can receive pharmacological treatment if required. Placebo Group (Control): Placebo + Cognitive stimulation. The placebo will be administered in the same way and with the same frequency and duration as Deprexil. In addition, they can receive pharmacological treatment if required.

Outcomes and Timepoint

Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.

Primary outcome(s):

Quality of Life (SF-36 health questionnaire. The questionnaire has 36 items distributed in 8 dimensions: physical function (10 items), physical role (4 items), body pain (2 items), general health (5 items), vitality (4 items), social function (2 items), emotional role (3 items) and mental health (5 items); item 2 is related to health transition. Each item is expressed on a scale from 0 to 100 with a point cut-off at 50, above and below which there are positive or negative health states. The change in final value with respect to the baseline value will be measured in the scores of the domains and summary scores of the questionnaire. The following categories will be established: poor Quality of Life if the total score is from 0 to 25, regular Quality of Life from 26 to 50, good Quality of Life from 51 to 75 and excellent Quality of life from 76 to 100 points). Measurement time: At baseline, month 3 and one week after the end of treatment.

Key secondary outcomes:

1. Functional capacity (It will be evaluated using the Lawton and Brody scale where 0 to 1 point is considered Total dependence, Severe dependence from 2 to 3 points, Moderate dependence from 4 to 5 points, Light dependence from 6 to 7 points, and Independence 8 points.). Measurement time: At baseline, month 3 and, a week after the end of treatment. 2. Cognitive Status (It will be evaluated using the Folstein Mini Mental State Examination (MMSE), the Reisberg Global Impairment Scale (GDS) and the Montreal Cognitive Assessment (MoCA) Test. The MMSE gives a score where from 24 to 30 points is evaluated as “no cognitive deficit”, between 18 and 23 points as “Slight cognitive deficit” and 17 points or less as “Severe cognitive deficit”. The GDS gives a score that ranges from 1 (absence of cognitive deficit) to 7 (very severe cognitive deficit) and the MoCA that gives a maximum score of 30 points, where a score equal to or greater than 26 points is considered normal (no alteration of cognitive functions) and less than 26 indicates alteration of cognitive functions). Measurement time: At baseline, month 3 and, a week after the end of treatment. 3. Brain metabolism (It will be evaluated through a neuroimaging study, Positron Emission Tomography (PET). The limbic structures (hippocampal complex, medial thalamus, mammillary body, and the posterior cingulate; or temporo-parietal region) and the structure will be studied. A favorable response will be considered if an increase in metabolism is observed when there are 2 or more standard deviations above the controls provided by the equipment as an average according to the areas studied in the final evaluation with respect to the baseline result, and unfavorable if contrary). Measurement time: At baseline and, a week after the end of treatment.
