The Promise of Leqembi

Dementia due to Alzheimer’s disease is a condition that has deeply affected the lives of many individuals and their families. However, with the introduction of Leqembi, the Alzheimer’s disease treatment landscape is shifting dramatically, bringing renewed hope and possibilities.

Leqembi, the result of tireless research and development, has demonstrated its potential to slow down the symptoms and progression of early onset dementia. Clinical trials have revealed promising outcomes, offering patients the opportunity to regain control over their lives, extend their cognitive abilities, and maintain their independence for longer periods.

This innovative drug works by targeting beta-amyloid plaques, a hallmark characteristic of Alzheimer’s disease dementia. By reducing the accumulation of these plaques in the brain, Leqembi aims to preserve cognitive function and delay the decline experienced by individuals with the condition. In effect, providing an opportunity for individuals to continue engaging in meaningful relationships, pursuing their passions, and enjoying a higher quality of life.

The Pros and Cons of Taking Leqembi

While the launch of Leqembi brings newfound optimism, it is crucial to consider both the advantages and potential drawbacks associated with this medication.


1. Slowing Disease Progression: Leqembi has shown promising results in clinical trials, suggesting its effectiveness in slowing down the progression of early Alzheimer’s disease by about 27% over the course of a year and a half. By preserving cognitive function, it offers patients greater odds of having an extended period of mental clarity and independence.

2. Enhanced Quality of Life: With Leqembi, individuals may have the opportunity to continue participating in activities they cherish, maintain relationships, and enjoy the things that bring them joy. This increased quality of life positively impacts not only patients but also their loved ones.

3. Availability of Expertise: As a trusted healthcare provider, Isaac Health stands at the forefront of advancements in the medical care of people with cognitive symptoms, including those in the early mild cognitive impairment and mild dementia stages. Isaac Health helps to close the gap in the current national shortage of Alzheimer’s-experienced specialists. With the ability to determine clinical eligibility, prescribe Leqembi, and monitor safety and efficacy closely over time, we reinforce our commitment to providing our patients with the best possible care and serving as a leader in the healthcare industry.


1. Strict Patient Criteria: The prescription of Leqembi requires meeting stringent criteria. Due to limited availability and potential side effects, the drug is reserved for individuals who meet specific eligibility requirements. This means that not everyone with mild cognitive impairment or mild dementia will qualify for Leqembi, which can be a source of disappointment and frustration. For instance, to qualify, patients must not have any other brain health issues such as stroke or Parkinson’s disease. The patient must also be in the early stages and have proven evidence of accumulation of amyloid plaques in their brain for Leqembi to function correctly. 

2. Potential Side Effects: Like any medication, Leqembi carries the possibility of side effects. Common side effects may include allergic reactions to the infusion (such as anaphylaxis), headaches, and fatigue. It is essential for patients to closely monitor their health and communicate any concerns to Isaac Health or their PCP healthcare provider.

3. Availability and Accessibility: While Leqembi holds tremendous promise, its availability may be limited initially – at least within the next year or two. This can pose challenges for individuals who may live in regions where access to the drug or specialists who can prescribe and monitor its safety is not yet widespread. Luckily, Isaac Health’s coverage is broad, including Florida, New York, and North Carolina – contact us to find out if you live in an area where we are able to see you. Additionally, there will be system-wide implications regarding the coverage of Leqembi. despite broader coverage following the traditional FDA approval, the cost of the medication may present a barrier for some patients as the cost of Leqembi is not yet covered by Medicare and Medicaid without being enrolled as part of an approved registry. Luckily, if eligible, Isaac Health works with you to figure out coverage details and will be among the first to become aware as the extent of this drug’s coverage evolves over time. 

Potential Health Risks of Taking Leqembi

While Leqembi offers potential benefits, it is essential to be aware of the health risks associated with the medication. Transparency and informed decision-making are crucial when considering any treatment option.

1. Allergic Reactions: Some individuals may experience allergic reactions to Leqembi. It is essential to be vigilant and seek immediate medical attention if any signs of an allergic reaction, such as rash, swelling, or difficulty breathing, occur.

2. ARIA: One of the main risks associated with Leqembi is the development of Amyloid-Related Imaging Abnormalities (ARIA). ARIA is characterized by fluid buildup or swelling in the brain as well as bleeding, which can lead to symptoms such as headaches, confusion, and seizures. Regular monitoring and communication with healthcare providers are essential to detect and manage ARIA effectively. It is also possible that people with certain genetic profiles may be at higher risk of these complications related to having one or more APOE4 alleles.

3. Drug Interactions: Leqembi may interact with other medications or supplements, potentially compromising their effectiveness or causing adverse effects, especially when it comes to risk of bleeding. It is vital for patients to inform their healthcare providers about all the medications and supplements they are taking to prevent any harmful interactions.
