Cannabidiol (CBD) is a chemical compound found in hemp, a close relative of marijuana. It is thought to have neuroprotective effects due to its interaction with the CB2 receptors in the brain. This creates an anti-inflammatory response in the brain's immune cells, reducing the amount of damage caused by inflammation. Studies have shown that CBD may have neuroprotective properties, helping to heal the brain and inhibit the development of neurological diseases such as Alzheimer's.
It can also stimulate the growth of new brain cells and reduce brain inflammation in some people.The effects of CBD vary depending on the dose. Lower doses (less than 15 mg) may have more stimulating effects, while higher doses may have more sedative effects. It is best used in combination with THC and other cannabinoids, such as cannabigerol (CBG) and cannabinol (CBN).A study conducted by researchers at UCL found that a single dose of CBD increased blood flow to the hippocampus, an important area of the brain associated with memory and emotions. CBD also targets the serotonin 1A receptor, which is why it is believed to be useful for treating pain, anxiety, and obesity.
It can also control the sleep-wake cycle; low doses can induce wakefulness and reduce daytime sleepiness, while larger amounts taken a few hours before bedtime can have a sedative effect.Overall, CBD has many potential benefits for brain health. It can protect neurons from degeneration, reduce inflammation, stimulate the growth of new brain cells, and improve mood and sleep quality. However, more research is needed to understand the neurobiological substrates that underlie its potential therapeutic effects.
