Lactobacillus helveticus-fermented milk improves learning and memory in mice.

Area of Science:

• Neuroscience
• Pharmacology
• Nutritional Science

Background:

• Cognitive impairments affect learning and memory.
• Neurodegenerative disorders like Alzheimer's disease pose significant health challenges.
• Lactobacillus helveticus-fermented milk products are explored for their potential health benefits.

Purpose of the Study:

• To investigate the effects of Calpis sour milk whey on learning and memory.
• To evaluate its efficacy in improving cognitive function in animal models.

Main Methods:

• Scopolamine-induced memory impairment was assessed using the spontaneous alternation behaviour test.
• Learning and working memory were evaluated with the novel object recognition test in mice.
• A total of 195 male ddY mice were used across the behavioral tests.

Main Results:

• Calpis sour milk whey powder significantly improved scopolamine-induced cognitive impairments at doses of 200 and 2000 mg/kg.
• Object recognition memory was also significantly enhanced at a dose of 2000 mg/kg.
• The study demonstrated a dose-dependent improvement in cognitive functions.

Conclusions:

• Calpis sour milk whey shows promise for preventing neurodegenerative disorders.
• It may enhance learning and memory in healthy individuals.
• Further human clinical studies are required to confirm these findings.
