CBD And Neuroprotection: How It Can Help Protect And Repair The Brain?

April 13, 2023

Neurons in the brain gradually die off in neurodegenerative illnesses like Alzheimer's, Parkinson's, and Huntington's diseases. These illnesses can cause various symptoms, such as behavioral changes, motor dysfunction, and cognitive decline, and they can significantly reduce a person's quality of life. Current therapies for neurodegenerative illnesses frequently have limited efficacy and severe side effects. Thus, there is a demand for new, efficient treatments that can shield and restore the brain.

Cannabidiol, or CBD, is a non-psychoactive substance in the hemp plant. Due to its possible therapeutic advantages for various conditions, including neurodegenerative diseases, it has attracted growing research interest in recent years. We will discuss the idea of neuroprotection in this piece and how CBD may present a promising strategy for defending and repairing the brain. We'll also go over how CBD exerts its effects on the brain.

Neuroprotection: What Is It?

In the case of damage, illness, or aging, neuroprotection means maintaining neural structure and function. In addition to promoting the repair and regeneration of damaged neurons, it includes preventing or minimizing the damage to neurons that may result from these circumstances.

There are many ways to practice neuroprotection, including avoiding oxidative stress, lowering inflammation, encouraging neurogenesis, and controlling neurotransmission. These methods work to prevent brain injury and encourage neuronal repair and regeneration, which can enhance performance and lessen symptoms.

For the creation of brand-new treatments for neurodegenerative diseases, neuroprotection is a crucial area of study. Neuroprotective therapies may give a more focused method of treating the underlying causes of these conditions, whereas current treatments frequently concentrate on managing symptoms.

How Does The Brain Respond To CBD?

The endocannabinoid system (ECS), a sophisticated communication system in the body that controls several physiological processes, including pain, inflammation, and mood, is affected by CBD. Endocannabinoids, receptors, and enzymes comprise the ECS, which collaborates to keep the body in equilibrium or homeostasis.

CBD may work in the brain by modifying the activity of different ECS receptors. For instance, it can attach to CB1 and CB2 receptors, which are found throughout the body and brain and have the power to affect various physiological functions.

The serotonin 5-HT1A receptor and the GABA-A receptor, implicated in anxiety and mood regulation, are two additional brain receptors with which CBD interacts. CBD can affect different parts of brain function, such as mood, cognition, and motor coordination, by modifying the activity of these receptors.

CBD has antioxidant and anti-inflammatory qualities and effects on receptors, which can help safeguard the brain from harm and encourage repair and regeneration. It might also encourage neurogenesis—the development of new neurons in the brain—which might enhance cognitive performance.

CBD's impacts on the brain are intricate and comprise several different mechanisms of action. It is a promising field of study for creating brand-new treatments for neurodegenerative diseases due to its capacity to modulate several physiological processes in the brain.

Neuroprotection, Oxidative Stress and CBD

In numerous animal models of neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, and multiple sclerosis, CBD can have neuroprotective qualities.

Reactive oxygen species (ROS) generation and the body's capacity to detoxify them can get into conflict, leading to oxidative stress. It can destroy cellular building blocks like proteins, lipids, and DNA and fuel the emergence of neurodegenerative illnesses.

The antioxidant qualities of CBD may help shield the brain from reactive stress. In a rodent model of Alzheimer's disease, CBD was able to lessen oxidative damage in the hippocampus, a brain region crucial for memory and learning. According to other research, a rat model of brain damage found that CBD improved memory and reduced oxidative stress.

The ability of CBD gummies to increase the activity of antioxidant enzymes in the brain, including superoxide dismutase (SOD) and catalase, may cause its ability to decrease oxidative stress. CBD boosted the activity of these enzymes and lessened oxidative damage in rat brain research, where oxidative stress was induced by hydrogen peroxide.

Inflammation And CBD

The immune system's natural reaction to injury or infection is inflammation. Chronic inflammation, however, has been linked to the emergence of several illnesses, including neurological conditions.

According to research, CBD has anti-inflammatory qualities that may help lessen brain inflammation. In a mouse model of Parkinson's disease, CBD was able to lower inflammation and enhance motor performance. In a mouse model of Alzheimer's disease, CBD could lower inflammation and enhance cognitive function.

CBD's ability to prevent the synthesis of pro-inflammatory cytokines and chemokines like tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) may cause its anti-inflammatory effects. Additionally, CBD may boost the creation of anti-inflammatory cytokines like interleukin-10 (IL-10).

Neurogenesis And CBD

The process of creating new synapses in the brain is called neurogenesis. Although it happens continuously throughout life, this process can be hampered by neurodegenerative illnesses.

CBD may encourage neurogenesis in rodent models of neurodegenerative diseases. In one research using a mouse model of Alzheimer's disease, CBD increased the number of new neurons in the hippocampus. Further research discovered that CBD could promote the growth of neural stem cells in the rat hippocampus.

Because of its effects on different brain signaling pathways, including the Wnt/beta-catenin pathway and the AKT/mTOR pathway, CBD may be able to stimulate neurogenesis. These networks are crucial in controlling how neural stem cells proliferate and differentiate.

Neurotransmission And CBD

The synapses in the brain use chemicals called neurotransmitters to communicate with one another. Different neurological and psychiatric disorders can emerge due to neurotransmitter-level imbalances.

Studies also show that CBD alters cerebral neurotransmission. According to one research, CBD raises brain levels of the neurotransmitter serotonin, which can help people feel less anxious and happier. Another research discovered that CBD could boost the GABA neurotransmitter system's activity, lessening anxiety and seizures.

The modulatory effects of CBD on the brain's various receptors, including the serotonin 5-HT1A receptor and the GABA-A receptor, may cause its impacts on neurotransmission. In addition, CBD can delay the reuptake of neurotransmitters like anandamide, extending their impacts on the brain.

CBD And Anxiety And Depression

Many neurological conditions, including neurodegenerative diseases, include anxiety and melancholy as prevalent symptoms. Since CBD can have both anxiolytic and antidepressant qualities, it can lessen the symptoms of both depression and anxiety.

In both animal models and people, studies have shown that CBD can lessen the signs of anxiety and melancholy. It indicates that CBD may help treat neurological disorders as a neuroprotective agent.


CBD has demonstrated tremendous promise as a neuroprotective agent in numerous rodent models of neurodegenerative diseases. The brain can be protected from harm by its anti-inflammatory and antioxidant properties. It can be repaired and restored to function by its capacity to support neurogenesis and modulate neurotransmission. Most of the research on CBD and neuroprotection was on animal models, so more studies are required to establish how well it works in people. Furthermore, it still needs to be determined what the best CBD gummies dosage and delivery strategy for neuroprotection should be.

Despite these drawbacks, CBD study is promising to create novel therapies for neurodegenerative diseases. It makes an appealing option for additional research due to its safety profile and accessibility as a natural compound. It's essential to remember that CBD shouldn't be used in place of standard medical care or as a panacea for neurodegenerative disorders. However, it merits further investigation as a potential therapy for these crippling conditions because it might give a complementary strategy to treatment.
