Trial Outcomes & Findings for New Approach for Treatment of Behavioral Disorders in Alzheimer's Disease (Alzheimer's Behavioral and Cognitive Disorders) (NCT NCT02462291)

NCT ID: NCT02462291

Last Updated: 2018-10-12

Results Overview

Through the use of Neuropsychiatric Inventory (NPI), the investigators assessed the frequency and the severity of the behavioral disorders. The total scale range of the NPI is 0-144, and higher values represent worse outcome.

Experimental Group (TR)
A group of 82 patients with AD performed a program of EET for 2 hours a day, 5 days a week for a total of 6 months. Ecological Environmental therapy: The program of EET consist of the physical interaction (visual, tactile, olfactory) between natural ecological elements such as flowers, trees, grass, and the patients with AD.
Control Group (CTRL)
A group of 81 patients with AD were treated with the standard therapy.

Timeframe: PRE and POST 6 months of treatment

Through the use of Mini Mental State Examination (MMSE) the investigators estimated the severity and progression of cognitive impairment. MMSE is a questionnaire that examines cognitive functions including registration, attention, calculation, recall, language, ability to follow simple commands and orientation. The scale range of the MMSE tests is 0-30, and higher values represent a better outcome.

Independence and level of activities of daily life (ADL) were evaluated with the Barthel index. Levels of ADL was measured by observing each resident's daily activities (eating, bathing, grooming, dressing, transfers from bed to chair, mobility on level planes, stairs, and getting on/off the toilet). The total score of the Barthel index is 0-100, and higher values represent a better outcome.

Levels of cortisol was measured via saliva samples using plain Sarstedt Salivette collection devices (Nümbrecht, Germany). Samples will be collected at 6.30 AM, 11.30 AM, and 6.30 PM. Immediately after collecting the saliva samples, were centrifuged for 2 min at 1,000 rpm. Purified saliva was stored in a freezer at -20 °C, and subsequently analyzed. Cortisol levels was determined by a time-resolved immunoassay with fluorometric detection.
