Alzheimer Disease Clinical Trial
— EFA-POfficial title:
Effects of Exercise on Cognitive Performance of Patients With Alzheimer-type Dementia. Pilot Study.
A program that combines high intensity aerobic exercise (<85% of Heart Rate Reserve) with
resistance, progressive and moderate intensity intervals, carried out in primary care, is
effective in terms of a smaller increase in respect to the baseline measurement in the total
score of the ADAS cognitive section (Alzheimer Disease Assessment Scale-Cognitive
section),in the control group that receives an intervention similar to low intensity (30-40%
of Heart rate reserve).
We Expect a difference of at least 3 points between the means of the increments between the
intervention and control group.

Inclusion Criteria: Subjects aged between 55 and 85 who meet, at the time of entry into
the study, clinical criteria compatible with probable AD according to the criteria of the
National Institute on Aging and the Alzheimer's Association, under mild or DCL-Alzheimers
(Folstein MMSE> 19/20, GDS 3-4), diagnosis will be performed by specialist neurologists
according to standard practice. Patients should be able to perform physical activity on a
cycle ergometer or treadmill and also must exist a caregiver who agrees to accompany him
to the physical exercise sessions. Exclusion Criteria: Central nervous system disease history with the possibility of neuropsychological impairment (stroke, epilepsy, meningitis, severe head trauma). History of alcohol and drug abuse. Hachinski Ischemic Scale = 7. Major depression diagnosed(CIE-10). History of severe psychiatric disease. Predictable changes in medication that may affect cognitive performance. Visual or auditory perceptual disorders that limit neuropsychological assessment. Unstable heart disease, severe behavioral problems that make impossible the intervention, or any condition judged by the investigator that advises against the intervention. - |

Primary | Change in cognitive performance that is measured in a blinded way with the cognitive section of the ADAS scale (Alzheimer's Disease Assessment Scale) at 0, 6 and 12 | Cognitive performance is measured in a blinded way with the cognitive section of the ADAS scale (Alzheimer's Disease Assessment Scale) at 0, 6 and 12. ADAS is an instrument designed to assess the severity of cognitive disorders (ADAS-Cog) and noncognitive (ADAS-cog) in patients with Alzheimer-type dementia (ATD). The ADAS-Cog, that we use, consists of 11 items that assess mainly memory (3 items, 27 points), orientation (1 item, 8 points), language (5 items, 25 points) and praxis (2 items, 10 points). The maximum score is 70 points.The higher the score, the greater the cognitive impairment.This is the primary outcome measure most frequently used in clinical trials with drugs. | 0, 6 and 12 months | Yes |
Secondary | Global cognitive performance | Global cognitive performance is measured with Test Barcelona TBR-B neuropsychological battery (abreviated version).The ADAS-COG wich is focused on the most devastated areas by Alzheimer's disease, will be complemented by the TBA-B, which has been developed in our environment, makes possible a more global assessment, and also presents adequate psychometric properties. | 0, 6 and 12 months | Yes |
