The paper “Cannabinoids for the Treatment of Alzheimer’s Disease: A Narrative Review of the Preclinical and Clinical Evidence” (Alzheimer’s & Dementia: Translational Research & Clinical Interventions, 2023) is a narrative review of the preclinical and clinical evidence on the use of cannabinoids for the treatment of Alzheimer’s disease (AD).

Preclinical evidence

Preclinical studies have shown that cannabinoids have neuroprotective, anti-inflammatory, and antioxidant effects that could be beneficial for the treatment of AD. For example, cannabinoids have been shown to reduce amyloid beta (Aβ) production and aggregation, and to protect neurons from Aβ-induced toxicity. Cannabinoids have also been shown to reduce neuroinflammation and oxidative stress, which are two key pathological features of AD.

Clinical evidence

Clinical trials of cannabinoids for the treatment of AD are still in their early stages, but the results so far are promising. For example, a recent study found that CBD was effective in reducing cognitive decline and improving symptoms of behavioral and psychological symptoms of dementia (BPSD) in patients with mild to moderate AD. Another study found that THC was effective in improving sleep quality and reducing agitation in patients with AD.

Safety and tolerability

Cannabinoids are generally well-tolerated, with a low risk of serious side effects. However, they can cause some mild side effects, such as dizziness, fatigue, and drowsiness. CBD is particularly well-tolerated, with a very low risk of side effects.

Conclusion

The review concludes that cannabinoids are a promising treatment option for AD. However, more research is needed to confirm the long-term safety and efficacy of cannabinoids for AD, and to identify the optimal dosing regimen.

If you are considering using cannabinoids for AD, it is important to talk to your doctor first. They can help you weigh the risks and benefits of treatment and develop a treatment plan that is right for you.

Here are some of the key findings of the review:

• Cannabinoids have neuroprotective, anti-inflammatory, and antioxidant effects that could be beneficial for the treatment of AD.
• Preclinical studies have shown that cannabinoids can reduce Aβ production and aggregation, protect neurons from Aβ-induced toxicity, reduce neuroinflammation, and reduce oxidative stress.
• Clinical trials of cannabinoids for the treatment of AD are still in their early stages, but the results so far are promising.
• CBD has been shown to be effective in reducing cognitive decline and improving symptoms of BPSD in patients with mild to moderate AD.
• THC has been shown to be effective in improving sleep quality and reducing agitation in patients with AD.
• Cannabinoids are generally well-tolerated, with a low risk of serious side effects.
• CBD is particularly well-tolerated, with a very low risk of side effects.
• More research is needed to confirm the long-term safety and efficacy of cannabinoids for AD, and to identify the optimal dosing regimen.

The paper you mentioned, “Cannabinoids for the Treatment of Alzheimer’s Disease: A Narrative Review of the Preclinical and Clinical Evidence,” was published in Alzheimer’s & Dementia: Translational Research & Clinical Interventions in 2023. The study is a narrative review of the preclinical and clinical evidence on the use of cannabinoids for the treatment of Alzheimer’s disease (AD) ¹.
