Implications For Stroke Rehabilitation

Can the brain heal itself?

A stroke occurs when either a clot or rupture in a blood vessel in the brain blocks the blood supply and stops the affected area from receiving the oxygen and nutrients that it needs to keep cells alive and working.

Most strokes are caused by clots, and these are known as ischemic strokes. A temporary clot that clears itself is known as a transient ischemic attack, which is also referred to as a mini-stroke.

When the affected area of the brain stops receiving the blood that it needs, brain cells die and the corresponding part of the body stops working properly or fails to work at all.

Often, the approach to rehabilitation therapy that individuals receive following a stroke focuses on helping them to compensate for the disability. The researchers propose that their study points to an alternative approach.

Our findings, says senior study author Jin-Moo Lee, a professor of neurology, suggest that we may be able to stimulate recovery by temporarily vacating some brain real estate and making that region of the brain more plastic.

One way to do that might be by immobilizing a healthy limb, he adds.

Can The Brain Heal After Lack Of Oxygen

A full recovery from severe anoxic or hypoxic brain injury is rare, but many patients with mild anoxic or hypoxic brain injuries are capable of making a full or partial recovery. Furthermore, symptoms and effects of the injury are dependent on the area of the brain that was affected by the lack of oxygen.

New Insights Into Brains Repair System Point To Improved Stroke Therapies

Dr. Walter Koroshetz, deputy director of the National Institute of Neurological Disorders and Stroke, discusses brain-computer interfaces and stroke recovery. New research is revealing how the stroke-damaged brain can respond to treatment, even after the crucial first six months when most recovery typically occurs, a leading stroke expert said at a briefing arranged by AAAS with support from the Dana Foundation.

Dr. Walter Koroshetz, deputy director of the National Institute of Neurological Disorders and Stroke, said research on the brains plasticity as well as some striking developments in robotics and brain-machine interfaces are giving new hope for stroke patients.

He called the science of stroke recovery the brightest and most exciting area in stroke research. But in remarks at the 22 May Capitol Hill briefing hosted by AAAS in conjunction with Rep. Chaka Fattah Koroshetz offered some sobering statistics on the prevalence, impact and cost of stroke.

What Are The Links Doctors Found Between Fish Oils Brain Trauma And Healing

To recap, your brain may heal itself. You must help facilitate the process if you suffered a traumatic brain injury. We know that guys like Matt Hughes are into healing oils like CBD. But here, we will discuss an oil type found primarily in specific species. This oil is a particular type of lard like extract pressed from the flesh of oily fish like anchovies, salmon, and bass. Omega-3 itself is a fatty acid, which includes eicosapentaenoic acid and docosahexaenoic acid. These are precursors of a type of eicosanoids, but no scientific data demonstrates these will reduce inflammation in the body. These oils also remain tied to the improvement of hypertriglyceridemia.

With all the talk of brain injury healing oils in the news and former MMA star Matt Hughes suffering a TBI after getting hit by a train, this is a hot topic. From a personal injury law perspective, a magic potion to heal the brain could come in handy. Omega-3 derivatives, EPA, and DHA, remain essential components of human cell membranes that reduce inflammation present in many severe traumatic brain injury cases. And we also know that these two fatty acids play a critical role in human heart development.

The Brain Could Repair Itself With Help

Jocelyne Bloch: After An Injury, Can The Brain Heal Itself ...

Neurosurgeon Jocelyne Bloch knows about the brains failure to heal itself perfectly, from stroke care to car crash injuries. But now, she believes, in doublecortin-positive cells, she and her team have found the secret to neuronal repair.

They are stem cell-like cells, highly adaptable, which can help regenerate and reconstruct when extracted from the brain and then pumped back into an injured region of the same brain. So according to Bloch, with a little help the brain might be able to repair itself.

Yes, this can be a breakthrough in neuroscience. Lets hope little by little to understand more about this wonderful organ: the human brain.

Whats Going On In A Traumatized Brain

Traumatized brains look different from non-traumatized brains in three predictable ways:

  • The Thinking Center is underactivated.
  • The Emotion Regulation Center is underactivated.
  • The Fear Center is overactivated.
  • What these activations indicate is that, often, a traumatized brain is “bottom-heavy,” meaning that activations of lower, more primitive areas, including the fear center, are high, while higher areas of the brain are underactivated. In other words, if you are traumatized, you may experience chronic stress, vigilance, fear, and irritation. You may also have a hard time feeling safe, calming down, or sleeping. These symptoms are all the result of a hyperactive amygdala.

    At the same time, individuals who are traumatized may notice difficulties with concentration and attention, and often report they cant think clearly. This, not surprisingly, is due to the thinking center being underactivated.

    Finally, survivors of trauma will sometimes complain that they feel incapable of managing their emotions. For example, if someone spooks them as a prank, they may experience a rapid heart rate long after the joke is up, or may have a hard time just letting go of minor annoyances. Even when they want to calm down and feel better, they just cant. This is in large part due to a weakened emotion regulation center.

    Does The Brain Heal After Years Of Substance Abuse

    Neuroplasticity is the brains ability to reorganize itself by forming new neural connections throughout life. Neuroplasticity allows the neurons in the brain to compensate for injury and disease and to adjust their activities in response to new situations or to changes in their environment. Thats great news for people in early recovery who may be concerned about feeling in a funk. It gets better. Your brain does eventually heal itself.

    This neuroplasticity or brain plasticity is the more recent discovery that gray matter can actually shrink or thicken neural connections can be forged and refined or weakened and severed. Changes in the physical brain manifest as changes in our abilities. For example, each time we learn a new dance step, it reflects a change in our physical brains: new wires that give instructions to our bodies on how to perform the step.

    But there are practical things you can do to help speed the process up. Roc & Doc talk more about it in this latest episode.

    A common concern for people recovering from active addiction is the worry that theyll never feel like they once did. Like theyre consigned to a foggy existence. Its the fear that theyve irreparably damaged the sense of being totally in touch with the fullness of their feelings.

    Roc shares his personal experience with this fear early on and his journey out of the funk.

    Doyles Problem Solved Algae To The Vegans Omega

    There is no evidence Doyle received a traumatic brain injury, but if he did, he is already receiving the best post-accident treatment. There is no way you can look like Doyle, discussed above, unless you have nutrition dialed in. And at his age, his songwriting keeps getting better and better. So if I were a betting man, I would bet Doyle was getting some of his Omega-3s from seed, nuts, etc. But for him to maintain his high level, he is likely to get the more bioavailable types of fatty acids from algae-based plants. Last time we checked, algae can create a vegan-friendly form of essential DHA.

    After all, you are what you eat. And fish get their DHA from gobbling up large amounts of DHA containing eating phytoplankton. And phytoplankton gets its DHA from consuming microalgae. When you think about it, all DHA is just microalgae. Guys like Doyle are probably just going straight to the source, so they dont have to eat the fish stuck in the middle of the food chain transaction. Omega-3 DHA is available online and at many health food stores as algal oil from fermented from microalgae. Consuming DHA may help your brain heal from catastrophic, cognitively harmful injuries.

    EPA and DHA are omega-3 fatty acids in fish oil vital for normal brain function and development. People with depression or a mild decline in brain function should consider taking them from an animal source, as they may see improvements in brain function.

    The Brain Is Super Vulnerable

    Can the Brain Heal Itself From Trauma? Professor Russell Meares 5 of 9

    Your brain and your spinal cord together form what we call the central nervous system. Looking at a skeleton, have you ever asked yourself why the brain and spinal cord are the only organs in our body encased in bone? True, the lungs and the heart are also well protected by the rib cage. But when you look at the skull, it is basically a bony box with a few holes in it to let nerves leave the brain. The nervous system is unique compared to many other organs in that it does not expand or contract like your heart, lungs, and intestines do. Because there is no major movement, it is alright for the central nervous system to be entirely encased in bone. Why is the central nervous system so well protected? The answer is simple: because it is super sensitive and very vulnerable.

    Which organ of your body do you think youre injuring most often? Probably, your skin. Think about a time when you fell, your skin broke open and you had a wound like a scrape or a cut for some time. If this injury happened a while ago, chances are you wont even see the spot on your skin any more. Or maybe you can see a scar, but basically your skin was able to repair itself almost perfectly. Unfortunately, the brain and spinal cord are fundamentally different. If your brain gets injured, some damage may persist throughout the rest of your life.

    Improving Your Chances Of Recovering

    To improve your chances of recovering, you can spend some time learning about strategies and techniques to compensate for abilities that you may have lost as a result of the injury. This can include taking notes to make up for short-term memory loss or taking classes on how to approach the otherwise daunting task of rehab and therapy.

    Also, try to get back into the swing of things as early as possible . While rest is the usual recommendation for patients recovering from a wide range of injuries and ailments, when it comes to brain recovery, an interesting medical finding is that getting back to your usual daily routine can help expedite the recovery process.

    People who have suffered a stroke tend to be immobilized for a considerable amount of time after the stroke. Their ability to relearn simple tasks such as writing or walking can take a very long time. Recent findings suggest that reintroducing stroke patients to these kinds of activities earlier in the recovery process can help speed up their recovery.

    Every injury and every person is extremely unique. If youre struggling after a traumatic brain injury, be sure to work with medical professionals and do your own research to reach the best possible outcome for recovery.

    How Can We Sculpt The Brain

    We already know that brain plasticity is a key tool for facing challenges in our environment. Likewise, researchers have discovered that aspects such as cognitive reserve allow us to better deal with neurological conditions.

    The keys to being architects of our brain are actually pretty easy to apply. They greatly benefit our brain since they allow it to generate new connections. Theyre stimulating, protective, and optimizing.

    Lets see what neurologist Pascual-Leone advises:

    Prevention Is The Best Medicine For Brain Health

    To help keep your brain safe and prevent TBI:

    • Wear a seat belt every time you drive or ride in a motor vehicle.
    • Always buckle your child into a child safety seat, booster seat, or seat belt in the car.
    • Never drive under the influence of alcohol or drugs, including prescription medications that can impair the ability to drive.
    • Avoid high-risk sports and activities where you can hit your head .
    • Always wear a helmet and make sure your children wear helmets while playing contact sports, bike riding, horseback riding, skateboarding, snowmobiling, skiing, or snowboarding.
    • Do not dive in water less than 12 feet deep or in above-ground pools. Check the depth and check for debris in the water before diving.
    • Always hold handrails when going down stairs.

    Those Who Have Taken Drugs Will Eventually Ask Themselves A Question

    How the brain can repair itself and reconnect?

    Will I ever feel normal again? There are many factors that will determine the rate at which your body heals, so you should make sure to understand that before you get frustrated with your healing. It took time to cause the damage, and it will take time to reverse it as well.

    First, think about the factors that will determine how long it will be before you feel normal. They could include:

    • The length of time you took the drug
    • The type of drug you were on
    • The method of detox you completed
    • Your ability to go to therapy and/or group meetings
    • The amount of drugs you took

    These five factors will actually be very important to your ability to heal and to how long it will take to feel better.

    The brain is constantly changing. The drug that you took will affect it by changing the neurons in the reward sector, which will make you feel good every time you take the drug. The result of this change is more release of dopamine, and this will give you a rush of good feelings. The change in your feelings will last a short time, but the actual change to the brain will last longer.

    Your ability to stop cravings is also altered when this occurs. Now, when the body sees the drug or needs it, you will face more serious cravings for it. The amygdala, a part of the brain, has been altered, and it will trigger an urge for the drug when it wants it.

    Were Sculptors Of Our Own Brain

    The brain is full of complex constellations. Every day we learn more about that cosmic ocean that extends beyond our small planet and, additionally, were now skilled astronauts who enjoy exploring and discovering relevant data about our neural networks.

    • We know, for example, that every experience, thought, and behavior can modify our brain.
    • Weve also discovered a process called neurogenesis that clearly demonstrates that our central nervous system can continue to generate new neurons.
    • Studies such as the one carried out by Drs. Chunmei Zhao and Fred H. Gage from the University of California, San Diego state just how important this process is in the prevention and mitigation of the impact of health issues such as depression, memory loss, or neurodegenerative diseases.

    This is undoubtedly one of the most interesting areas of neuroscience because, until very recently, we believed that we were only capable of generating new neurons during the first years of our lives.

    Can You Heal A Damaged Brain

    No, you cannot heal a damaged brain. Medical treatments can just help to stop further damage and limit the functional loss from the damage. The healing process of the brain is not the same as the skin. When the skin gets damaged, such as due to minor skin wounds, it usually heals wells without leaving scars. Major wounds can heal with scarring. Skin healing is completed by replacing the damaged/lost cells with new ones. In the brain, the damaged cells are nerve cells known as neurons and neurons cannot regenerate. The damaged area gets necrosed and it is never the same as it was before.

    When the brain gets injured, you are often left with disabilities that persist for the rest of your life. Rehabilitation can help in functional recovery, but structural abnormality is hard to correct with available treatments.

    Can The Brain Heal Itself

    Until the 20th century, neurogenesis was thought to end after the development of the embryo. Starting in the second half of the last century, it was discovered that cells continue to be born in the brain throughout life. Today, this knowledge helps to understand the process of learning and memory and also how the brain is able to repair itself.

    In this brief guide we are going to answer the question Can the brain heal itself? We will establish at what point the brain is able to regenerate and create new cells to heal itself, what processes are involved and what are its limitations.

    How Could This Happen

    How long does it take to recover from a stroke?Can brain heal itself after it? – Dr.Anil R

    What happens is that the brain sort of rewires itself. Nerve cells sprout extensions that spread out and connect with nerve cells in other parts of the brain. This allows other parts of the brain to take over the jobs that used to be done by the part of the brain that was damaged.

    You can see this in Figure 2, showing results of a study called a functional magnetic resonance imaging scan. MRI scans use a very powerful magnet that switches on and off. When the magnet switches on, it makes atoms in the cells spin to line up with the magnetic poles of the magnet. When the magnet switches off the atoms spin back, and they give off radio signals that can be detected and mapped, so that images of the brain can be made: . Functional MRI assesses changes in blood flow in different parts of the brain during brain activity. The figure is explained in Box 1.
