Effects of THC-Free CBD Oil on Agitation in Patients With Alzheimer’s Disease
This is a randomized, double-blinded, placebo-controlled, crossover trial that aims to 1) determine the efficacy of THC-free cannabidiol (CBD oil) in reducing the severity of agitation among participants and 2) determine whether THC-free CBD oil can reduce the burden on caregivers and increase the participants’ quality of life.

Individuals with Alzheimer’s and other forms of dementia often go through a period of significant behavioral and psychological symptoms of dementia (BPSD). It is estimated that up to 90% of persons with dementia (PWD) experience behavior problems at some point. BPSDs can be challenging for both unpaid family caregivers as well as paid caregivers. Family caregivers provide the bulk of care for PWD and number over 15 million. One of the most common types of BPSDs is agitation with a prevalence of up to 87%, based on a recent systematic review. Agitation can lead to impaired daily functioning, prolongation of hospitalization, reduced time to institutionalization, and is associated with higher mortality. Additionally, agitated behavior is associated with increased injury to both patients and caregivers. Based on the 2018 Alzheimer’s disease drug development pipeline report almost 70% of clinical trials related to BPSD are dedicated to agitation behavior. Finding ways to address agitation is necessary to improve overall quality of life for PWD and their caregivers. Currently, there are no medications available specifically for the treatment of BPSDs. The use of benzodiazepines, antipsychotics and mood stabilizing agents are common, but the risks and side effects often outweigh any benefits.
Several small studies have investigated the use of cannabinoids in the treatment of pathology and symptomology of Alzheimer’s disease (AD), as well as treatment of the agitation component of BPSD. A handful of these studies showed that the symptoms of BPSD were decreased with the use of cannabinoids. However, due to small sample sizes, study design, and short trial duration of these studies, the efficacy of these agents on BPSD cannot be confirmed. In addition, cannabinoids have demonstrated anti-oxidant and anti-inflammatory effects, and both processes have been indicated as major contributors to the neurologic effects of AD. Some evidence exists that agitation is related to this neuroinflammatory process. This study will examine the effects of cannabinoids on the behavioral and psychological symptoms of individuals with a dementia diagnosis.
CBD Oil for Alzheimer’s & Dementia: How to Use & Dosage
Hemp and CBD oil were federally legalized with the 2018 Farm Bill, but scientists have been researching cannabidiol and its potential benefits for many years prior to the cannabis boom.
CBD products are gaining popularity at a rapid pace, mainly due to the number of conditions potentially alleviated by this compound.
Researchers are discovering new symptoms that CBD may be able to treat or help with in some way — from anxiety to inflammation and neurodegenerative diseases like dementia. CBD may provide relief to thousands of people across the country.
In this article, I’ll dive specifically into the potential application of CBD for dementia and the collateral damage it does to individuals suffering from this disease.
I want to explain the ins and outs of using CBD oil, how it can interact with dementia, and guide you through the brands that currently offer the best CBD products on the market.
Best CBD Oils for Dementia
Not all CBD is made equal. In fact, there’s a large degree of difference when it comes to the quality of ingredients in different CBD oils.
If you’re using this supplement for dementia, it’s important to find something clean and as high quality as possible — preferably in a higher potency.
Here are my top 3 recommended products that meet those requirements:
1. Royal CBD
Get 15% off all Royal CBD products. Use code “CFAH” at checkout.
- Royal CBD uses organic hemp from local farmers
- The company makes its products with supercritical CO2 extraction
- Available as full-spectrum CBD and isolate
- Four potency strengths to choose from: 250mg, 500mg, 1000mg, and 2500mg
- The oil is potent — it contains up to 83.3 mg of CBD in each mL
- Suspended in premium MCT oil for better taste and improved absorption
- Every batch of product has been tested for potency and purity in a 3rd-party laboratory
- The 2500 mg oil is available only in the unflavored option
- Royal CBD products are slightly more expensive than the competition given the quality of ingredients this company uses
My Thoughts on Royal CBD:
Royal CBD is a rising star of premium CBD oils — offering high-quality products made from organically-grown American hemp. The oil contains the full spectrum of cannabinoids and terpenes, providing the synergy from these compounds and contributing to the higher efficacy of CBD.
Aside from extracting its oil with pressurized CO2, Royal CBD sends each batch of product to independent laboratories for testing. This is used to confirm the potency and purity of every bottle sold.
The oil offers 250 mg to 2500 mg of full-spectrum CBD per bottle, suiting both novice consumers and experienced users or those with more severe symptoms.
I like how this product tastes. Because it’s suspended in high-quality MCT oil, it doesn’t leave that bitter, earthy aftertaste on the tongue. The flavor is masked by nutty rather than earthy notes.
But if you prefer other forms of administration, Royal CBD offers convenient soft gel capsules (25 mg of CBD per piece) and isolate-based gummies (10 mg of CBD per count). These forms may not have the fastest onset but are easier to dose and take on the go.
- CBDPure’s products are sourced from organic hemp grown in Colorado
- The company uses CO2 extraction in all their products
- The oil is sold in larger bottles than the competition (60 mL)
- These products are made with full-spectrum hemp extract
- The entire product lineup has been tested in an independent laboratory for quality assurance
- Narrow product range
- The oil is less potent than Royal CBD
- No isolates available
My Thoughts on CBDPure:
If you don’t know where to start and need plenty of information about each stage of the CBD oil manufacturing stage, CBDPure is one of the best brands you can choose. This company is very transparent and uses organic hemp in every product they offer.
Similar to Royal CBD, CBDPure prefers to keep things simple, offering two types of products — oil drops and capsules.
Their CBD oil comes in 60 mL bottles but is slightly less potent than Royal CBD, so you may choose this option if you benefit from lower doses, which isn’t common for people with dementia symptoms.
If you want a product that will give you more CBD and offer consistent dosing, you may go for CBDPure softgels. Each capsule comes with 25 mg of full-spectrum cannabidiol.
- CBDistillery uses Colorado-grown hemp
- The company’s products are available as ‘full-spectrum’ or ‘pure oil’ (zero THC)
- Broad product selection
- The oil is very potent — up to 5,000 mg of CBD per bottle
- CBDistillery sends samples of their CBD oil to a third-party laboratory for thorough content analysis
- It’s one of the most affordable brands on the market
- Their hemp isn’t organic
- The CBD oil is available only in the unflavored version
My Thoughts on CBDistillery:
CBDistillery is a Colorado-based brand with a diverse product selection. Out of all their products, my favorite is their full-spectrum CBD oil. Interestingly, this product is also available as pure oil, with no THC inside.
The oil comes in a wide potency range, from 250 to 5,000 mg of total CBD. The company caters to different types of CBD consumers and budgets.
Their oil may not be as high quality as Royal CBD or CBDPure — it’s not made from organic hemp — but this is well justified by the cost of their products. CBDistillery doesn’t sell the best CBD oil out there, but that’s definitely the best CBD oil in this price range.
On top of making affordable CBD products, CBDistillery is known for its influence on raising awareness about the health benefits of cannabis. They have created the #CBDMOVEMENT hashtag to provide education for customers in their social media.
What is Dementia?
Dementia is not a disease, per se. Instead, it’s a group of conditions that impair the functioning of your brain.
Generally, dementia is characterized by the deterioration of at least two important brain functions, such as weakened judgment and memory loss. As a matter of fact, any form of dementia can compromise cognitive functioning.
As with every health condition, there are certain symptoms that can help diagnose dementia, namely:
- Impairment of motor functions and coordination
- Memory loss usually noticed first by a close family member
- Personality changes
- Difficulty with problem-solving or reasoning
- Anxiety, agitation, depression, or paranoia
- Hallucinations and awkward behavior
- Problems handling complex tasks
Is Dementia the Same as Alzheimer’s Disease?
Alzheimer’s is the most common form of dementia, so dementia is just a category that Alzheimer’s Disease belongs to. Yet, there are other forms of dementia besides Alzheimer’s.
Dementia can be categorized into four different forms of dementia:
- Frontotemporal dementia: the type where the nerve cells in the temporal and frontal lobes of the brain degenerate. Frontotemporal dementia affects the parts of the brain that control behavior, language, and personality
- Lewy Body Dementia: the most common type of progressive dementia, Lewy Body Dementia occurs when abnormal clumps of protein start to form in the brain.
- Vascular Dementia: it’s the second most prevalent form of dementia. It’s caused by the damage in the blood vessels that limits direct blood supply to the brain and may lead to blood vessel clogs or stroke.
- Mixed dementia: it typically involves some combination of Alzheimer’s Disease and other forms of dementia. While Alzheimer’s may strike those over the age of 65, mixed dementia occurs upon further progression.
What Are the Benefits of CBD for Dementia?
CBD has been proposed by scientists as a natural alternative for many serious conditions including memory loss conditions, anxieties, and sleep disorders.
CBD is a potent antioxidant, anti-inflammatory, and neuroprotectant, so it may greatly improve brain functioning, which is essential in slowing and halting the progression of neurodegenerative diseases.
Below I explain how CBD oil could improve different forms of dementia based on the latest scientific findings.
1. Alzheimer’s Disease
Research shows a clear link between CBD and the reduction of inflammation and brain cell decline.
Inflammation increases the negative impact of Alzheimer’s disease. It’s a core cause of this condition. The more inflamed the brain, the greater the damage.
Alzheimer’s sufferers often show a path of rapid decline and degeneration of brain cells in certain regions. Scientists have recently found that CBD has the potential of improving the plasticity of the hippocampal region — the part of the brain responsible for cognitive functioning and forming memories.
In clinical trials, researchers have found that the endocannabinoid system is involved in neurotransmission, neuropathology, and neurobiology of different forms of dementia, including Alzheimer’s Disease.
2. Vascular Dementia
As mentioned, people who have vascular dementia typically encounter problems with planning, reasoning, memory, judgment, and other thought processes due to brain damage from reduced blood flow to their brains.
A 2016 study conducted by the National Institute of Health (NIH) found that activating cannabinoid receptors in the brain promoted the recovery of blood flow to the brain.
3. Parkinson’s Disease Dementia
Parkinson’s is a progressive neurodegenerative disease mainly affecting middle-aged and elderly people. Some symptoms of dementia may be the result of Parkinson’s disease — referred to as Parkinson’s disease dementia.
Scientists suggest that Parkinson’s disease may derive from lowered dopamine production and is most commonly expressed by muscular strains, tremors, and slow, flawed movement.
A digestive imbalance may also be a significant factor in the progression of Parkinson’s and the seriousness of its symptoms. Cannabinoids such as CBD have been shown to produce neuroprotective and antioxidant effects on the brain which, along with its anti-inflammatory properties, can be effective in managing Parkinson’s disease-induced dementia.
4. Lewy Bodies Dementia
Lewy Bodies is a scientific name for the alpha-synuclein protein deposits in the brain. These buildups can lead to problems with judgment, sleeping, behavior, movement, and mood.
Research has found that CBD may reduce anxiety and stabilize mood. In addition, the anti-inflammatory effects of CBD can reduce the severity of motor symptoms and help with sleep regulation.
5. Frontotemporal Dementia
As the brain loses more cells in its frontal or temporal lobes, this can trigger symptoms of depression and psychosis. Unlike many antipsychotic drugs, CBD may alleviate tremors, anxiety, and rigidity without the side effects associated with prescription drugs.
6. Huntington’s Disease Dementia
Also known as Huntington’s chorea, this disease is an inherited disorder that leads to degeneration of brain cells — which often results in symptoms of dementia.
The earliest symptoms of this condition are often mild and involve problems with mood and concentration. As the disease progresses, a person may suffer from a general lack of coordination and an unsteady gait (walking motion).
A 2016 study conducted by researchers from the University of Madrid discovered that CBD’s antioxidant and anti-inflammatory properties can be beneficial for managing Huntington’s disease and is safe even at very high doses.
What Experts Say About CBD Oil and Dementia
Scientists are going to use a CBD/THC oral spray Sativex to treat dementia patients in the first major trial in the UK. The study is led by researchers at King’s College London and funded by Alzheimer’s Research UK.
Researchers will be investigating the efficacy of Sativex, a drug already approved for patients with multiple sclerosis, by observing 60 patients between the age of 55–90 who are living in care homes for the duration of the trial. The study will aim at easing aggression and agitation, one of the main symptoms of dementia.
Dag Aarsland, a psychiatrist and the professor supervising the trial says:
“Most often, people associate Alzheimer’s disease with memory problems, but this is just one aspect of a complex condition that can affect people in different ways. Many people with Alzheimer’s can become agitated or aggressive, and this can pose difficulties for the person with the condition and those closest to them.”
If full-spectrum extracts prove effective as a dementia treatment, this can be a breakthrough for modern medicine considering that scientists have been struggling to come up with effective solutions for almost two decades.
“With no new dementia treatments in over 15 years, it is vital that we test a wide range of approaches to find effective ways to help people living with the condition,” said David Reynolds, Ph.D., of Alzheimer’s Research U.K. Reynolds underlines the importance of finding a medicine that will not only slow or stop the progression of dementia but also benefits people’s day-to-day performance.
“Based on some preliminary studies in other populations, like younger individuals with bipolar disorder and schizophrenia, as well as animal studies, there is at least some reason to theorize these drugs would have a benefit,” follows Dr. Nathan Herrmann, head of geriatric psychiatry department at Sunnybrook Health Sciences Centre in Canada, showing support for his colleagues in the UK.
Sativex has equal amounts of THC and CBD. Hemp-derived CBD oil contains only 0.3% THC and there are no trials that would look into the effects of this cannabis solution on dementia.
What’s the Best CBD Oil Dosage for Dementia?
There are no definite dosage guidelines when it comes to using CBD oil for dementia. However, various studies have been performed on the efficacy of different CBD doses for Alzheimer’s patients.
A study conducted in 2014 found that higher concentrations of CBD may be required until the effects take hold. The study was conducted on transgenic mice.
Given the lack of regulation in the CBD marketplace, the best thing you can do is observe the effects of different dosages and report to a foundation or science institute that specializes in seeking new forms of dementia treatment. With more self-reports from patients, healthcare professionals will be able to come up with some general guidelines for people with dementia in the future.
Where to Buy CBD Oil for Dementia
If you’ve been considering taking hemp-derived CBD oil for dementia, you can buy one in a local cannabis dispensary or search for CBD products online.
I prefer buying CBD oil online. The majority of CBD supplements are sold this way, so you get access to a wider range of products. Cannabis dispensaries have plenty of CBD supplements as well, but they may not carry the best products out there, not to mention that they might have stood on the shelves for a long time after arrival — which is not the best way to store CBD oil.
Buying CBD oil online is also more convenient. You can easily check the reputation of your potential supplier. Always make sure that your manufacturer uses organic hemp, makes its products with CO2 extraction, and posts testing results from 3rd-party laboratory screening.
Finally, online stores are less expensive than dispensaries. Usually, you will pay around twice as much for CBD oil in a local dispensary than you would for a product ordered online.
It’s worth waiting the extra 2-3 days to get exactly what you’ve been looking for without spending an arm and a leg.
Final Thoughts on Using CBD Oil for Dementia
Dementia is a severe neurodegenerative condition. It’s not a disease per se; instead, it’s a set of symptoms that describe a predictable set of symptoms. It can take many forms, from Alzheimer’s Disease to vascular dementia and Lewy Bodies Dementia. Dementia can also result from the progress of other neurodegenerative diseases, such as Parkinson’s or Huntington’s Disease.
Scientists have been investigating the neuroprotectant properties of CBD and its influence on neurodegeneration for quite some time now. While the evidence isn’t conclusive yet, results from animal studies and preclinical trials indicate that the endocannabinoid system and cannabinoids can be used to prevent neurodegeneration and reverse its impact with consistent administration.
If you’re interested in trying CBD oil for dementia, make sure to contact your doctor first to figure out whether CBD is good for you, especially if you’re already using some medication.

Can CBD Help Seniors with Alzheimer’s & Dementia?
CBD, or cannabi diol , has been suggested as a treatment to help seniors with dementia manage their symptoms. While there is currently no evidence to show that CBD can stop, reverse, or prevent dementia , there is research that sho ws that it could help manage symptoms. This could be great news for families and seniors who are struggling with the effects of dementia. In this post, we will explore what CBD is along with how CBD can be used to help seniors deal with Alzheimer’s or related dementias.
What Is CBD?
Let’s start with the basics of CBD. It comes from the hemp plant , which is related to the marijuana plant . The plant is dried and the resin is extracted. This compound contains 2 parts: tetrahydrocannabinol (THC) and cannabidiol (CBD).
- THC is the recreational form of cannabis, which is associated with generating a “high.” In the US, products with more than 0.2% THC are considered illegal.
- CBD is the medicinal form of cannabis that generally helps improve mood and reduce damage caused by inflammation. It does not CBD is legal in various forms in 47 US states. It also does not exhibit the potential for dependence or health-related problems.
This distinction is important because CBD does not have the intoxicating feeling associated with THC. Instead, it has been shown t o have anti-anxiety properties that can help manage behavior and promote calm. Additionally, CBD is the main ingredient in recent FDA-approved medication, Epidiolex, to treat epilepsy.
CBD can be administered in different forms, but the most common is as oil, which can be dropped onto the tongue , contained in gel capsule s, or applied to the skin directly. However, it is also available in pill forms or as an inhalant.
What Are the Benefits of CBD for Seniors with Dementia?
CBD is commonly used to help with anxiety, insomnia, poor sleep, and even pain relief. B ecause CBD has been shown to help reduce anxiety and agitation, it is believed that it can help reduce these symptoms in seniors with dementia.
Because of how dementia affects the brain, a senior may become agitated or anxious in everyday situations. Sometimes this agitation can even turn vio lent. But remember that these behavior changes are caused by the disease and are not your loved one’s fault. CBD may be able to help alleviate these symptoms .
Additionally, Dementia Care Central indicates that CBD may also help:
- Reduce inflammation
- Reduce oxygen buildup
- Stimulate the brain & reduce the decline of memory and other brain functions
Let’s dive deeper into how CBD could help in each of these areas.
Inflammation is the body’s natural response to injury. You might be used to seeing inflammation around a cut or wound. However, neuroinflammation is also associated with various forms of dementia. For example, Alzheimer’s disease causes clumps of proteins to build up in the brain. This can make it harder for the brain to function over time. As a result, the body may respond with inflammation in the area, which could make it even harder for the brain to make connections. However, CBD may help reduce that inflammation and help with dementia.
Oxygen buildup ties in with inflammation in the brain. As brain tissue expands, oxygen is released. So, the more inflammation, the more oxygen that builds up. As more oxygen is released into the brain, the brain loses functionality. This can result in memory loss or other brain deterioration. Oxygen is also released when the body is stressed, which happens often for seniors with dementia. CBD may help reduce stress and reduce the negative effects of oxygen on the brain.
Memory & Brain Function
As dementia progresses, brain tissue actually dies and function is lost for good. This process can take the time or it can happen very rapidly. In some trials, CBD showed promising results to help stop or even reverse the loss of brain function and memory loss in dementia patients. Additionally, CBD may help stimulate the brain to help keep connections within the brain and help seniors potentially delay the effects of dementia.
While this information gives us much hope in the fight against dementia, know that only small clinical trials have been conducted to determine the effects of CBD on dementia, making it difficult to come to a scientific conclusion. However, scientists are continuing to conduct rese arch to help further our ability to help those with dementia.
Are There Any Risks Associated with CBD?
The World Health Organization (WHO ) has stated that “no public health problems. have been associated with the use of pure CBD.” Additionally, it does not exhibit addictive properties and has not been shown to cause any health risks.
However, this applies to pure CBD. There are some retailers who produce CBD products with other ingredients or strains of CBD that have been tainted with other substances. Some companies also misrepresent their products and place different packaging labels on the products. This could pose a risk for your loved one, so i t’s important for you to obtain any CBD products through a company that has been approved by a third party , meaning the products have been tested independently for quality.
If you or your loved one is interested in using CBD to manage symptoms, make sure you talk to a doctor first to evaluate the risks and discuss the best options.
There is still much we do not know when it comes to CBD and its effectiveness in treating the symptoms of dementia. However, we are hopeful that new research and medications will be developed that will end dementia for good!
