Dietary restriction during adolescence improves the memory performance of old female Wistar rats in an onset- and duration-dependent manner
Age-related declines in sensory, motor, and cognitive abilities are a major risk factor for neurodegenerative diseases. Dietary restriction (DR) can slow or postpone these changes, improving memory, learning, and cognitive abilities, but may not always yield positive results. In this study, we examined the impact of 30% DR (70% of ad libitum daily intake) during adolescence on the short-term (STM) and long-term (LTM) memory performance in 6- and 18-month-old female Wistar rats. The effects of DR were examined in three onsets and durations: DR1 (28th to 35th day of life), DR2 (35th to 42nd day
