[Omega-3 fatty acids and acetylcysteine diet supplementation effects on learning performance]

Area of Science:

• Nutritional Neuroscience
• Biochemistry
• Animal Models

Background:

• Omega-3 fatty acids are vital for brain function, development, and cardiovascular health.
• Dietary intake of essential fatty acids plays a crucial role in overall well-being.

Purpose of the Study:

• To investigate the impact of omega-3 polyunsaturated fatty acids (N3-PUFA) and acetyl-1-carnitine (ACC) on cognitive performance.
• To evaluate the combined effects of N3-PUFA and ACC on cognitive function in a rodent model.

Main Methods:

• Sixty male Wistar rats were divided into control and experimental groups.
• Experimental groups received N3-PUFA, ACC, or a combination for 36 weeks.
• Cognitive performance was assessed using a multiple T-maze labyrinth.

Main Results:

• All supplemented groups (N3-PUFA, ACC, and combination) showed significant decreases in maze completion time.
• The N3-PUFA group improved by up to 33.88%, ACC by 34.28%, and the combination by 32.33%.
• The control group showed a smaller decrease in maze completion time (17-18%).

Conclusions:

• Dietary supplementation with polyunsaturated fatty acids significantly enhances cognitive performance.
• Combined N3-PUFA and ACC supplementation shows potential for improving cognitive function.
• These findings highlight the importance of omega-3 fatty acids in supporting brain health.
