Objective: ) on memory and cognitive functions in patients with Alzheimer's disease (AD). Materials and Methods: In this randomized controlled trial, 60 AD patients with mild to moderate cognitive disorder were randomly allocated into an almond group (10 g/day powdered sweet almond plus 1 teaspoon of powdered rock candy along with their previous prescriptions), or the control group (continue previous prescriptions) for 3 months. The Mini-mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), Clinical Dementia Rating (CDR), and Functional Assessment Staging (FAST) questionnaires were completed at the beginning and the end of the study.

Duration of memory deficit was 2.8±0.92 and 3±1.2 months in the almond and control group, respectively (p=0.473).
