Cannabis use has been linked to morphological and functional changes in the brain, as well as cognitive impairment and an increased risk of mental health issues. Neuroimaging studies have shown that CBD can modulate brain activity and connectivity in areas related to psychosis and anxiety, which may explain its therapeutic effects. Research has also suggested that CBD may have neuroprotective properties, such as promoting the growth of new brain cells and reducing inflammation. To understand how CBD affects the brain long-term, future studies should focus on long-term CBD treatment of psychiatric patients in combination with neuroimaging evaluations.
The results of these studies could help elucidate the neural factors underlying the therapeutic effects of CBD. It is important to note that the effects of CBD can vary from person to person. To use CBD effectively for brain health, it is important to identify the best product, dosage, and duration of treatment for you. Studies have shown that CBD can reduce anxiety, fear, and immobilization associated with stressful or life-threatening events.
It can also reduce autonomic arousal under conditions of emotional and physical stress. Interestingly, there are several areas of the brain that are positively combined with ARAS after CBD treatment. In summary, CBD has been shown to modulate networks relevant to psychiatric disorders during the resting state and several cognitive tasks. It has also been shown to have dissonant effects compared to THC during the resting state and during several cognitive tasks.
To understand how CBD affects the brain long-term, further research is needed.
