The aging of the world's population brings a silent and growing challenge: the advancement of dementias, which affect more than 55 million people worldwide, according to the World Health Organization. Amidst the search for therapies that alleviate symptoms and preserve quality of life, medical cannabis has emerged as a possible ally — albeit under cautious scrutiny from the scientific community.

Initial research indicates that compounds such as cannabidiol (CBD) and tetrahydrocannabinol (THC) may exert neuroprotective effects, reducing brain inflammations and neuronal death, as well as modulating pathways related to mood and sleep. In animal models and laboratory studies, the results are promising: there are signs that cannabinoids may help protect the brain against cognitive decline.

But when the focus turns to clinical studies in humans, the scenario changes. Trials conducted so far are small, short-term, and with different methodologies, making it difficult to reach a solid conclusion. The scientific evidence is still considered limited and inconclusive, although reports from patients and caregivers bring positive experiences: less agitation, more tranquility, and a more predictable routine.

Promises, Limits, and Next Steps

As optimistic as the findings may seem, there is no evidence that cannabis can slow the progression of dementia or recover lost cognitive functions. Studies point to specific benefits, especially in behavioral symptoms, but reinforce the need for caution.

Experts emphasize that each case is unique and should be closely monitored by healthcare professionals, especially because the elderly population, the most affected audience, usually takes other medications and is more vulnerable to side effects.

Nevertheless, the topic arouses hope and curiosity. As new research advances, the expectation grows that cannabinoids may occupy a legitimate space in the care of people with dementia, not as a miraculous promise, but as an evolving alternative that combines science, compassion, and responsibility.
