Lewy Body Dementia

Lewy Body Dementia (LBD) is a progressive neurological disorder that affects both the cognitive and motor functions of an individual. It is characterized by the presence of abnormal protein deposits, known as Lewy bodies, in the brain, which disrupt normal brain functioning. LBD is the third most common form of dementia after Alzheimer’s disease and vascular dementia, affecting approximately 1.4 million people in the United States alone. The symptoms of LBD often overlap with those of other neurodegenerative conditions, making it challenging to diagnose accurately. In this article, we will discuss the causes, symptoms, diagnosis, and available treatment options for managing Lewy Body Dementia effectively.

What is Lewy Body Dementia?

Lewy Body Dementia (LBD) is a progressive neurodegenerative disorder characterized by the presence of abnormal protein deposits called Lewy bodies in the brain. These deposits disrupt normal brain functioning, leading to cognitive and motor impairments. LBD is often considered an umbrella term, comprising two related conditions: dementia with Lewy bodies (DLB) and Parkinson’s disease dementia (PDD).


The symptoms of LBD can vary from person to person, but may include:

  1. Cognitive decline: Memory loss, difficulty with problem-solving, and impaired attention or concentration.
  2. Visual hallucinations: Vivid and recurring visual hallucinations that may involve people, animals, or objects.
  3. Parkinsonism: Motor symptoms similar to those seen in Parkinson’s disease, including stiffness, shuffling gait, tremors, and balance issues.
  4. Fluctuating alertness: Sudden changes in attention, alertness, or wakefulness throughout the day.
  5. Sleep disturbances: Rapid eye movement (REM) sleep behavior disorder, which involves physically acting out dreams during sleep.
  6. Autonomic dysfunction: Disruptions in the autonomic nervous system can lead to blood pressure fluctuations, constipation, urinary problems, and temperature regulation issues.


The exact cause of LBD remains unknown, but it is believed to be linked to the accumulation of Lewy bodies in the brain. These abnormal protein deposits, primarily composed of alpha-synuclein, interfere with the communication between brain cells and contribute to cell death. While genetic factors may play a role in some cases, the majority of LBD cases appear to be sporadic, with no clear genetic link identified.


There is currently no known way to prevent LBD, as the precise cause of the disorder remains unclear. However, maintaining overall brain health and reducing the risk of developing other neurodegenerative conditions may be beneficial. Some general recommendations for promoting brain health include:

  1. Regular physical activity: Engaging in regular exercise can help improve cardiovascular health, maintain mobility, and support cognitive function.
  2. Healthy diet: Consuming a balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats can promote overall health and well-being.
  3. Mental stimulation: Participating in mentally engaging activities, such as puzzles, reading, or learning new skills, can help support cognitive function.
  4. Social engagement: Staying socially active and maintaining strong connections with friends and family can contribute to emotional well-being and mental health.

If you suspect that you or a loved one may have LBD, it is crucial to consult with a healthcare professional for proper evaluation and diagnosis. Early intervention and appropriate treatment can help manage symptoms, improve the quality of life, and provide support for individuals living with Lewy Body Dementia and their caregivers.

Medical Marijuana as a Treatment for Lewy Body Dementia

There is limited research on the use of medical marijuana specifically for Lewy Body Dementia (LBD). However, some studies and anecdotal evidence suggest that it may help alleviate certain symptoms associated with the disorder. Medical marijuana interacts with the endocannabinoid system, which plays a role in regulating various physiological processes, including inflammation, pain, and sleep.

How does medical marijuana help?

Medical marijuana may help address some LBD-related symptoms through several mechanisms:

  1. Pain relief: Cannabinoids such as THC and CBD can help manage chronic pain that may be experienced by individuals with LBD.
  2. Sleep improvement: Medical marijuana has been shown to improve sleep quality and reduce REM sleep behavior disorder symptoms, a common issue in LBD patients.
  3. Anxiety reduction: Some strains of medical marijuana can help alleviate anxiety and promote relaxation, improving the overall well-being of individuals with LBD.

Cannabinoids and Terpenes for Lewy Body Dementia

Several cannabinoids and terpenes may be particularly effective in addressing symptoms associated with LBD:

  1. THC (tetrahydrocannabinol): THC is known for its psychoactive effects, but it also possesses analgesic and sedative properties that may help manage pain and improve sleep in LBD patients.
  2. CBD (cannabidiol): CBD has demonstrated anti-inflammatory, analgesic, and anxiolytic effects without causing psychoactive side effects. It may help reduce pain, inflammation, and anxiety for those with LBD.
  3. CBN (cannabinol): CBN is a lesser-known cannabinoid with potential sedative and analgesic effects, which may contribute to its therapeutic benefits in managing sleep disturbances and pain in LBD patients.
  4. Linalool: Linalool is a terpene that exhibits sedative and anxiolytic effects, potentially providing relief for sleep disturbances and anxiety in LBD patients.
  5. Myrcene: Myrcene is a terpene with sedative and analgesic properties, which may help manage pain and improve sleep quality in individuals with LBD.

It is crucial to consult with a healthcare professional experienced in cannabinoid medicine when considering medical marijuana as a treatment for LBD. They can help determine the appropriate strains, ratios of cannabinoids, and dosages tailored to an individual’s specific needs and circumstances. Further research is needed to fully understand the long-term effects and efficacy of medical marijuana in managing Lewy Body Dementia and its symptoms.

Dosage and Consumption Methods

Recommended dosage:

Figuring out the right dose of medical marijuana can be hard because people’s reactions to cannabinoids and terpenes can be very different. Factors such as the specific condition being treated, the patient’s weight, metabolism, and prior experience with cannabis all play a role in determining the right dosage.
Most of the time, it is best to start with a low dose and slowly increase it until you get the effects you want while minimising any possible side effects. For patients who are new to medical marijuana, starting with 2.5–5 mg of THC or CBD and slowly titrating upwards is often advised.

However, consulting a healthcare professional experienced in medical marijuana is essential to developing a personalised dosing plan tailored to the patient’s needs.

Consumption methods:

There are several methods of consuming medical marijuana, each with its advantages and disadvantages. Some common consumption methods include:

  1. Inhalation (smoking or vaping): Inhalation provides rapid onset of effects, usually within minutes, making it suitable for patients requiring immediate relief. However, smoking may pose respiratory risks, while vaping has been associated with lung injuries in some cases.
  2. Oral ingestion (edibles, capsules, tinctures): Ingesting medical marijuana provides longer-lasting effects compared to inhalation but has a slower onset, typically taking 30 minutes to 2 hours for effects to be felt. This method is suitable for patients requiring sustained relief but may require careful dosing to avoid overconsumption.
  3. Topical application (creams, balms, patches): Topicals can provide localised relief for conditions such as arthritis or skin disorders without producing psychoactive effects. The onset of action and duration of effects can vary depending on the product formulation and individual absorption rates.
  4. Sublingual administration (tinctures, dissolvable strips): Sublingual products are absorbed through the mucous membranes under the tongue, providing rapid onset of effects without the need for inhalation or ingestion. This method offers discreet consumption and precise dosing.

Obtaining a Medical Marijuana Card

Why get a medical marijuana card?

Getting a medical marijuana card is helpful for patients who are looking for other ways to treat their conditions.

  1. Legal protection: A medical marijuana card allows patients to possess, use, and in some cases, cultivate cannabis for medical purposes, within their state’s legal limits.
  2. Access to quality products: Medical marijuana dispensaries offer a wide range of tested and regulated cannabis products, ensuring patients receive safe and effective medication.
  3. Tax savings: In some states, medical marijuana patients are exempt from certain taxes applied to recreational cannabis sales.
  4. Professional guidance: Medical marijuana cardholders have access to healthcare professionals who can provide personalised recommendations, dosing advice, and ongoing support.

How to apply:

The process of obtaining a medical marijuana card varies by state but generally involves the following steps:

  1. Consult with Marijuana specialists to determine if medical marijuana is appropriate for your condition and obtain a written recommendation.
  2. Complete an application with the required documentation, including proof of residency, identification, and the healthcare professional’s recommendation.
  3. Submit the application to the appropriate state agency, along with any required fees.
  4. Await approval and issuance of the medical marijuana card.

Risks and Side Effects

Potential risks:

While medical marijuana can offer relief and improve the quality of life for many patients, it also carries certain risks and side effects. Some potential risks associated with medical marijuana use include:

  1. Dependency and addiction: Although the risk of addiction is considered lower than that of opioids or alcohol, some individuals may develop a dependency on cannabis.
  2. Impaired cognitive function: THC, the primary psychoactive compound in cannabis, can impair memory, attention, and reaction times, particularly with prolonged or heavy use.
  3. Respiratory issues: Smoking cannabis can cause respiratory problems, including bronchitis and lung irritation. Vaping has also been linked to lung injuries in some cases.
  4. Mental health concerns: High doses of THC or predisposition to mental health disorders can lead to increased anxiety, paranoia, or exacerbate existing mental health conditions.
  5. Drug interactions: Medical marijuana may interact with other medications, either enhancing or diminishing their effects. It is essential to discuss potential drug interactions with a healthcare professional before starting medical marijuana therapy.


Medical marijuana might not be right for every patient, especially those who already have certain health problems or risk factors. Contraindications to medical marijuana use may include:

  1. Personal or family history of substance abuse or addiction
  2. Severe liver or kidney disease
  3. Severe cardiovascular disease
  4. Pregnancy or breastfeeding
  5. History of psychosis or other severe mental health disorders
  6. Allergies or hypersensitivity to cannabis or its components

Legal Status

Where is it legal?

In the United States, the laws about medical marijuana are always changing. Currently, over 30 states and the District of Columbia allow its use under certain conditions. Each state has its own rules and a list of medical conditions that are allowed to use medical marijuana.

Even though some states have made medical marijuana legal, it is still illegal at the federal level because it is a Schedule I substance under the Controlled Substances Act.

This difference between state and federal laws can make it harder for medical marijuana patients to get jobs, find housing, or travel across state lines, among other things. Patients should research their state’s guidelines and remain aware of potential legal risks.


Medical marijuana could help relieve symptoms and improve the quality of life for many people with long-term or debilitating illnesses.

When thinking about this treatment option, it’s important to know the right dose, how to use it, how to get a medical marijuana card, possible risks, side effects, and legal status.

Work closely with a doctor or nurse who knows a lot about medical marijuana to find out if it is a good and safe choice for your needs.

As the legal landscape surrounding medical marijuana continues to evolve, staying informed about changing regulations and guidelines is essential to ensuring responsible and compliant use.
