The Centers for Disease Control and Prevention states that an average of 795,000 people each year in the United States suffer a stroke. The majority of these are new strokes. Knowing whether you have a high risk of suffering a stroke is important, but so is knowing what you can do to lower your risk.
One important step you can take for stroke prevention is exercise. Learn more about what causes strokes and why exercise can be such an important prevention tool.
Understanding Strokes: What They Are and What Causes Them
You can think of a stroke as the equivalent of a heart attack on your brain. It is a life-threatening condition that occurs when a part of your brain doesn’t receive an adequate amount of blood. Strokes usually occur from experiencing bleeding in the brain or a blocked artery.
There are two main types of strokes: ischemic and hemorrhagic strokes. Ischemic strokes happen when cells don’t get enough blood and therefore don’t get enough oxygen. An ischemic stroke occurs if something blocks blood vessels in the brain. Blood clots can lead to ischemic strokes.
Hemorrhagic strokes lead to bleeding in or around your brain. It can occur if a blood vessel in your brain breaks open and causes bleeding that puts pressure on your brain tissue. It can also happen if you experience bleeding in the space between the brain and its outer covering.
The symptoms of a stroke vary depending on which areas of the brain it affects. You can experience one or more symptoms like:
- Difficulty speaking
- Blurred or double vision
- One-sided weakness
- Paralysis
- Loss of muscle control on one side of the face
- Loss of coordination
- Dizziness
- Vomiting
- Nausea
- Slurred speaking
- Partial or total loss of one of the senses
- Memory loss
- Seizures
- Headaches
The cause of the stroke can depend on the stroke type. Ischemic strokes usually occur because of blood clots, while hemorrhagic strokes happen as a result of high blood pressure, brain cancers, brain aneurysms, and more.
Some factors can put you more at risk of suffering a stroke. These are:
- Obesity
- Smoking
- Poor diet
- Physical inactivity
- Diabetes
Strokes have the potential to occur at any age, but the risk rises as you grow older. If there’s a history of strokes in your family, you’re also more likely to suffer from one yourself. Drinking too much alcohol is another way to increase your chances of a stroke.
How Exercise Helps to Prevent Strokes
Exercise plays a role in reducing several stroke risk factors, including diabetes, high blood pressure, and even stress. For primary stroke prevention, high blood pressure is the most important risk factor. Physical activity helps control blood pressure because it improves vascular function.
Type 2 diabetes increases the chances of having a stroke because excessive blood glucose levels over time increase fatty deposits. These deposits narrow or block blood vessels, cutting off blood to the brain. Exercise helps improve glycemic control, so it can be an important way of managing your type 2 diabetes.
Exercise also helps promote lower cholesterol levels. Having high cholesterol levels causes plaque buildup in your arteries, including those that send blood to your brain.
For older people or those with certain medical conditions, turning to light exercise may be beneficial. Some options include gardening, taking walks, and even doing housework. The key is to avoid being inactive for long periods.
For adults who can manage moderate exercise, it’s important to engage in at least 2 ½ hours of exercise per week. You can choose activities like cycling, brisk walking, swimming, or anything else that gets your heart rate up.
Other Lifestyle Changes for Stroke Prevention
Besides adding more physical exercise to your life, you can also turn to other strategies to help prevent a stroke. For one thing, if you smoke, you should quit. Smoking significantly damages blood vessels, triggering plaque formation and even causing blood vessel breakdown. Smoking increases your blood pressure, too.
You should take a close look at your diet. Eating a diet that causes higher cholesterol levels can contribute to the development of plaque. Plaque narrows arteries and makes blood clots more likely.
Stick to lean proteins, unsaturated fats, fruits, and vegetables, and avoid sugary foods and saturated fats. You should also add fiber-rich foods to your diet. It is also important to cut down on the amount of alcohol you drink. Alcohol increases your blood pressure, making blood clots more likely to happen. Blood clots can cut off your blood supply and lead to strokes.
Another important step you can take if you want to prevent a stroke is to incorporate stress management techniques into your day. Stress makes the heart work harder, which increases blood pressure.
At the same time, sugar and fat levels in the blood also increase when you experience stress. They impact arterial health as well. All these factors may lead to the development of clots. Finding ways of managing stress goes a long way toward addressing these issues.
You can opt for doing deep breathing exercises, as well as focusing on mindfulness strategies to help you stay in the present. Some people benefit from meditation or yoga, while others do better if they take time to exercise. Taking up relaxing hobbies is another excellent option.
Regenerative Medicine: Can It Help with Strokes?
Working to prevent strokes is important, and your strategies for doing so can be as simple as adjusting your diet and adding exercise to your daily routine. If you’ve already experienced a stroke, however, you can also use these strategies to prevent future ones. Lowering your blood pressure, managing your diabetes, and lowering stress levels can all help.
If a previous stroke has left you with symptoms that affect your life, a treatment option that shows promise is stem cell therapy. Stem cell therapy encourages your body to heal using its natural processes, allowing you the chance to regain some of your brain’s lost function. Ask your doctor about regenerative medicine options like stem cell therapy.

Osteoarthritis (OA) is a chronic joint condition that causes pain and lack of mobility through the progressive degradation of joint cartilage. While there are several current pharmaceutical, physical therapy, and surgical treatments to address the symptoms of OA, researchers are interested in developing new therapeutic treatment approaches to address the relentless progression of the condition.
Considering their documented biocompatibility, immunomodulatory properties, and ability to precisely target specific cells and tissues, exosomes have recently emerged as a promising therapeutic option as a drug delivery system (DDS) for the treatment of OA. Specifically, these exosome-based strategies have demonstrated a safe and effective way to enhance cartilage repair, mitigate inflammation, and alleviate the persistent pain associated with OA.
While the benefits of exosome-based DDSs have been demonstrated in numerous studies, according to the author of this review, the specific application of this option for the purpose of treating OA has not been sufficiently explored.
In this review, Lu et al. summarize the emerging developments surrounding exosome-based DDSs of OA and highlight the present challenges associated with this evolving therapeutic option.
Recent studies have demonstrated the benefit of using exosomes for the delivery of drugs designed to treat OA. Specifically, researchers have found that exosomes derived from mesenchymal stem cells (MSCs) are able to be effective carriers for the delivery of specific molecules that lead to the promotion of chondrogenesis and improvement in cartilage regeneration. These same exosomes have also demonstrated themselves to be effective carriers for the localized delivery of anti-inflammatory drugs known for their potent anti-inflammatory and immunosuppressive effects.
Other studies show the potential of exosomes as an effective way to deliver growth factors to the affected joint in a targeted and sustained manner. The same exosomes have also demonstrated promise as a platform for gene delivery to areas affected by OA; a few of the notable advantages include the ability to safeguard genetic material from degradation and enable targeted delivery to specific cells and tissues.
While there is seemingly unlimited potential for using exosomes as DDSs in OA treatment, Lu et al. also call attention to several technical challenges and limitations that need to be addressed in order to fully maximize their potential and to ensure their safe application. These challenges and limitations include figuring out how to obtain a consistent supply of high-quality exosomes, developing effective methods that allows for efficient loading and controlled release of therapeutic molecules within exosomes, and a current lack of comprehensive long-term data regarding the safety and biocompatibility of exosome-based therapies.
Despite these challenges and limitations, the authors conclude that exosomes have emerged as highly promising candidates for drug delivery in OA therapy and offer numerous advantages over conventional delivery systems.

According to the Centers for Disease Control and Prevention, more than 795,000 people have strokes every year in the United States, and about 610,000 of these are first or new strokes. Recovering from a stroke can be a complex process that involves many types of therapies, and one option that shows promise is stem cell therapy.
Stem cell therapy promotes growth factors and offers relief from inflammation, providing the possibility of healing the damage the stroke caused. Learn more about stem cell therapy when used for the recovery period after a stroke.
How Strokes Affect the Brain
A stroke is like a heart attack, except it takes place in your brain. It occurs when something blocks the blood supply to the brain, not allowing the organ to get the oxygen and nutrients it needs. If your brain doesn’t receive blood, its cells begin to die off or suffer damage, making it impossible for the organ to do its job.
Your brain controls everything your body does, including how you move and how you think, feel, and communicate. The results of a stroke are immediate.
The two main types of strokes are ischemic strokes and hemorrhagic strokes. Ischemic strokes are the most common type and are caused by blockages. They can occur when:
- A blood clot forms in the main brain artery.
- A blockage forms in the small blood vessels deep within the brain.
- A blood clot from the heart or another type of blockage travels via the bloodstream to an artery supplying the brain.
Hemorrhagic strokes occur when there’s bleeding in or around the brain. They can be the result of a blood vessel bursting in the brain, or a blood vessel on the surface of the brain may burst and leak blood in the area between the skull and the brain.
When you have a stroke, the areas of the brain it affects determine the kind of issues you can struggle with.
Some people experience weakness and paralysis in certain parts of their body, while others struggle with language and the processes of speaking or understanding what other people say. A stroke can even affect what your voice sounds like.
Other issues you may experience include:
- Balance problems
- Incontinence
- Trouble swallowing
- Visual problems
- Extreme fatigue
- Feeling pain
You may also struggle with mental processes like memory, concentration, understanding, and perception. Strokes can even affect your emotions.
Understanding Stem Cell Therapy: What Are Stem Cells?
Stem cells are the body’s building blocks. They are responsible for creating organs, tissues, and even your immune system. They are undifferentiated cells that can become and create specialized cell types. In other words, they can become any cell within the body, depending on where they’re placed.
Stem cells can also divide indefinitely, either creating other stem cells or specialized cells. When used to help the recovery period after a stroke, stem cells can differentiate into brain cells.
When they’re used in the brain, they don’t integrate and become neurons that reconstruct circuits. They instead start pumping out growth factors that enhance the recovery process, allowing new blood vessels and neurons to form. All of this helps make the brain more flexible, giving it a chance to recover after a stroke.
Neuroplasticity is what’s necessary for people who’ve suffered a stroke. It is the ability of the brain to rearrange its circuits, basing the organization on your behaviors.
Benefits of Stem Cell Therapy After a Stroke
Stem cell therapy is minimally invasive. You don’t have to worry about procedures that require long recovery processes or force you to spend time in the hospital. When you get stem cell therapy, the process is fast and can be done as an outpatient treatment.
Stem cells don’t just mask the symptoms of the damage the stroke caused. Experiencing pain after a stroke many times means turning to pain medications, which temporarily give you relief but also have unpleasant side effects. When you turn to stem cell therapy, your brain gets what it needs to start healing.
One of the most important things that stem cell therapy offers is the chance to relieve inflammation. When you suffer an injury of any kind, including a stroke, your body’s natural healing process causes inflammation.
This type of swelling, however, doesn’t allow a regular flow of blood to the injured area. Without the right degree of circulation, the damaged area doesn’t receive nutrients or oxygen, which makes healing more difficult. Stem cells help reduce inflammation, making the process of healing easier.
How the Stem Cell Therapy Process Works
Mesenchymal stem cells (MSCs) have been studied for their potential therapeutic applications in various medical conditions, including stroke. MSCs have several properties that make them attractive candidates for stroke therapy:
- MSCs possess anti-inflammatory properties that can help modulate the immune response and reduce inflammation in the brain following a stroke. Excessive inflammation is a key contributor to secondary damage after a stroke.
- MSCs can modulate the immune system, potentially suppressing harmful immune responses while promoting tissue repair and regeneration.
- MSCs secrete various growth factors and neurotrophic factors that support neuronal survival, growth, and differentiation. These factors can contribute to the repair and regeneration of damaged neural tissue.
- MSCs can stimulate the formation of new blood vessels (angiogenesis), which is crucial for supplying oxygen and nutrients to the damaged brain tissue.
- While the ability of MSCs to differentiate into neurons is limited, they may contribute to neural repair indirectly by interacting with the local environment and supporting the survival of existing neurons.
Is Regenerative Medicine Right for You?
Suffering a stroke can be devastating, leaving you with lasting damage and impacting your quality of life. Along with physical therapy and other treatments your doctor recommends, patients are exploring their options with stem cell therapy. Stem cell therapy and other regenerative medicine options offer the opportunity to give your brain the tools it needs to start healing. By helping reduce inflammation and bringing growth factors to the treatment area, stem cell therapy provides the chance to promote neuroplasticity and start healing.

No one wants to grow old. That is apparent from the huge amounts of money people spend on anti-aging products and services each year. These products and services include everything from lotions to more invasive options like plastic surgery.
However, healthier aging is possible without relying on invasive procedures. Stem cell rejuvenation, for example, offers promising results for people searching for ways of going through a healthier aging process.
Intrinsic vs. Extrinsic Aging: What to Know
Intrinsic aging refers to the various traits you inherited, including collagen and elastin production levels, hormonal balance, and more. The thinning lips or particular types of wrinkles you see on your parents, for example, are intrinsic aging traits, and you will likely deal with them as you age, too.
Intrinsic aging doesn’t just refer to visible signs of aging. It also includes the damage that occurs to organs and other body tissues as you get older. How fast an organ deteriorates and how fast tissues regenerate to keep up with the damage all depends on intrinsic aging.
Extrinsic aging refers to the things that you can control about aging. It includes lifestyle choices like smoking, not eating correctly, and so much more.
Both intrinsic and extrinsic factors in aging begin to accumulate, sending messages of aging to the core of stem cells. Thus, everything associated with aging can be seen through the lens of stem cells.
Understanding Stem Cell Rejuvenation
Introducing youthful stem cells into the body can make it easier to rejuvenate existing cells, helping the body age in a healthier way and even offering the chance to reverse some of the effects of aging.
As you age, your cells are not as efficient at replicating as they were when you were younger. This leads to cells getting damaged and dying off. Inefficiency in cell replication leads to aging bodies.
Stem cells are the cells that create specialized cells. They are your body’s building blocks. To combat the natural aging process, stem cells can help regenerate damaged tissue. This is because they can be made into various cell types.
Stem cells can also stimulate the production of growth factors and other molecules that trigger healing mechanisms, helping maintain healthy tissues. Chronic, low-grade inflammation is associated with aging, and stem cells help to reduce inflammation.
They do this by impacting the processes of white blood cells. Macrophages are white blood cells that are integral to the immune system. M1 macrophages can create inflammation, while M2 macrophages reduce it.
Stem cells help transform M1 macrophages into M2 macrophages. This stimulates the process of reducing inflammation.
Another way stem cells help battle against the aging process is by modulating the immune system. They have the potential to maintain a healthy immune system and delay the type of immune dysfunction that comes with age.
Oxidative stress also plays a role in aging. Free radicals damage cells, leading to many of the issues the aging process causes. Stem cells help combat the effects of oxidative stress.
Stem cells also have the potential to affect visible signs of aging. They can increase collagen production, which is vital for maintaining skin flexibility and firmness. As part of the aging process, your collagen production decreases, leading to the formation of fine lines and wrinkles.
The Process of Stem Cell Rejuvenation
Stem cell rejuvenation begins with choosing the right type of stem cells. The main stem cell type used is mesenchymal stem cells.
Mesenchymal stem cells (MSCs) are a type of multipotent stem cell that can differentiate into a variety of cell types. They are typically found in the stromal or connective tissue of various organs and tissues in the body.
MSCs were first identified in the bone marrow, but they can also be isolated from other tissues such as adipose (fat) tissue, and umbilical cord tissue.
MSCs possess immunomodulatory properties, meaning they can regulate the immune system. They can influence the activity of immune cells, such as T cells and macrophages, and have anti-inflammatory effects. This makes them potentially useful for treating conditions with immune system dysregulation.
MSCs exhibit low immunogenicity, meaning they are less likely to provoke an immune response when transplanted into a recipient. This characteristic makes them potentially suitable for allogeneic (from a donor) transplantation.
MSCs have been studied for their potential therapeutic applications in regenerative medicine, tissue engineering, and treatment of various diseases, such as autoimmune disorders, cardiovascular diseases, and musculoskeletal conditions.
If from a patient’s own tissues, the healthcare provider extracts the stem cells and prepares them for injection. They then inject the stem cells into the treatment area to provide relief from inflammation while encouraging your body to start regenerating tissues at the same time.
Because stem cells have the ability to endlessly duplicate themselves, the benefits of stem cell therapy for rejuvenation purposes can only improve over time.
Benefits of Stem Cell Rejuvenation
Stem cell rejuvenation procedures are minimally invasive. They require an extraction of stem cells and then an injection or the introduction of an IV. Other procedures that target aging can be significantly more invasive, leading to long recovery times.
The results continue to improve over time. This is because stem cells will go on to multiply where they were injected, potentially leading to more powerful results.
Stem cell rejuvenation can target the aging process at the cellular level, helping reduce inflammation and prevent oxidative stress. Stem cells may lead to an increase in collagen production as well, which helps combat fine lines and wrinkles.
Choosing Regenerative Medicine
Anti-aging solutions don’t have to involve invasive procedures or the reliance on options that take a very long time to work. Regenerative medicine treatments like stem cell therapy offer the chance to tackle the causes of aging at the cellular level.
Stem cells can offer anti-inflammatory results while also targeting free radicals and helping repair damaged tissues as well as damaged stem cells. By turning to regenerative medicine options, you have the chance to find rejuvenation solutions that can work.
