CBD and memory performance in old age – what does the current study really say?

Study Summary: CBD and Cognitive Functions

The following findings are based on a recent scientific mini-review study (Binkowska et al., 2025), which examined how CBD can influence memory performance, concentration, and overall mental performance. Important: This is not a single study, but a summary of multiple research works – representing the current state of science. The central question: Can CBD help improve brain performance in old age?

Why Memory Performance Declines with Age

The brain changes as we age. Typical effects are:

• declining memory performance
• reduced concentration
• slower information processing

These changes are normal – but they can significantly affect quality of life.

Therefore, many specifically look for ways to enhance their mental performance and keep the brain fit in the long term.

CBD as a Hope for Better Brain Performance?

CBD (cannabidiol) is a natural compound from the hemp plant – without psychoactive effects. According to the study, CBD could be particularly interesting for:

• protection of nerve cells
• reduction of inflammation in the brain
• support of memory performance
• improvement of concentration

How CBD Could Influence Memory Performance

Brain Protection (Neuroprotection)

The study shows: CBD acts antioxidatively and anti-inflammatory – two crucial factors for stable brain performance. This means: less cell damage = better conditions for strong memory performance.

Promotion of New Nerve Cells

Especially exciting: In animal studies, CBD was able to promote the formation of new nerve cells. This is directly relevant for:

• learning
• improving memory performance
• long-term mental performance

Influence on the Memory Center (Hippocampus)

The study shows that CBD increases blood flow in the hippocampus – the area of the brain responsible for memory performance.

What Do Human Studies Say About Concentration and Memory Performance?

This is where it gets especially interesting – but also honest: The current state of studies shows a mixed picture. Positive effects:

• improved brain activity
• better neural connectivity
• influence on areas responsible for concentration

But:

• no clear evidence for better memory performance in tests
• studies mostly with young, healthy people

Conclusion: The effect on mental performance is likely – but not yet conclusively proven.

Why Older People Might Benefit More

A key result of the review study: age is a decisive factor

This means:

• The brain changes over time
• The endocannabinoid system works differently
• CBD might have stronger effects in old age

Initial indications even show: Older participants tended to have better results in memory performance and concentration.

Bioavailability – Crucial for the Effect

Many underestimate this point: How you take CBD massively influences its effect. In our blog post, you can learn more about the topic of CBD bioavailability.

Major Research Gaps – What Is Still Missing

The study clearly shows – there are still many open questions:

• Long-term effects of CBD
• Optimal dosage for better memory performance
• Differences between men and women
• Combination with brain training

Conclusion – Can CBD Really Improve Memory Performance?

The scientific summary shows – cannabidiol has great potential for:

• better memory performance
• stronger concentration
• long-term mental performance

But:

• clear evidence in humans is still lacking
• especially in old age, more studies are needed

Conclusion: CBD is an exciting approach to support brain performance – but not a miracle cure.

HANAFSAN Insight: Holistic Approach for Better Brain Performance

Those who want to improve their memory performance should focus on several factors:

• exercise
• nutrition
• sleep
• mental training
• targeted natural support, for example through CBD oils
