A Recent Study Offers New Data On Brain Stimulation

brain stimulation presentation

A study from University of Pennsylvania researchers brought came with new data on the brain stimulation treatment.

To date, an effective solution for memory loss hasn’t been identified. As it is, a recent study from University of Pennsylvania researchers has sparked new life into a brain stimulation treatment previously disputed as only marginally beneficial.

The study, published in Current Biology, brings the world one step closer to solving memory loss in patients with epilepsy, brain trauma, or dementia.

It’s All in the Timing of the Brain Stimulation

This research was part of the Department of Defense’s Restoring Active Memory initiative. The goal of the four-year program is to develop an implantable device capable of restoring memory function.

While this study targeted and was completed for epilepsy patients, the DOD got involved due to the memory loss problems exhibited by soldiers who suffered traumatic head injuries.

The research team examined the process of deep brain stimulation using implanted electrodes. Previous attempts with this method showed mixed results. In some cases, it improved memory. However, the same pulses also worsened the recall is some of the instances. This study cleared up the confusion by proving that the effectiveness depends on the timing.

When the electric stimulation was delivered during a memory loss moment, the patients’ memory actually benefited from it. At the same time, when their memory was functioning well and they went through with the procedure, the electrical impulses seemed to impair their recall. As such, the team determined that the deep brain stimulation improved the memory function only if administered at the right moment.

This research could bring the “closed loop” treatment one step forward towards being used. A closed loop system of implanted electrodes works by monitoring the brain function in memory areas. As it does so, it also delivers a pulse. But only when the function is low. These sensitive systems could help bring the subtle difference needed for memory improvement.

This study could represent a turning point in neuroscience. The puzzle of the deep brain stimulation’s complicated nature could be one step closer to clarification. More research is needed to distil this concept into an actual therapy.

More Screen Time May Mean Less Sleep Time For A Toddler

toddler less sleep

Preliminary studies found that the more young children play video games, the less sleep they get.

Toddlers, even babies playing with smartphones and tablets can be seen everywhere nowadays. But as more and more young children are given electronic games to play, some parents and researchers are questioning their effects and consequences.

Preliminary studies found that the more young children play video games, the less sleep they get. These new touch screen games can help teach dexterity and sharpen mental skills. However, they shouldn’t take away the life-regenerating sleep kids need.

New Study Found That Spending More Time In Front of a Screen May Also Lead To Less Sleep

A new research showed that for every hour spent playing on a device, young children get 15 minutes less sleep. The study team stated that:
“It isn’t a very a massive amount when you’re sleeping  10 -12 hours a day in total, but every minute matters in young development because of the benefits of sleep.”
Most experts agree toddlers need their sleep. It is while sleeping that their bodies grow, their hearts are strengthened and weight regulated. Their immune function improves, and the attention span and learning skills increase.
Sleep also helps them store up the energy needed to face the next day. If more sleep meant less crying and tantrums, every parent would insist on it.A good night’s sleep for a toddler or baby can be ensured by limiting the amount of screen time during the day. Do not allow them to play on the devices after dinner. Instead, you could play board games, go for a walk or take playful baths. Once settled in bed, you can tell them stories or read books that are gentle and comforting and will help ensure your child gets an adequate amount of rest.

Sleep is one of the essential building blocks of a healthy body and mind, regardless of age. But for babies and toddlers, it is absolutely critical to mental and physical growth. Let the electronic games be an occasional activity and ensure that sleep regains its prominent place in the life of a child.

A paper presenting the study results of this new study was published in the Scientific Reports journal.

What Is Adult ADHD And What Are Its Signs?

adult adhd sign

Adult ADHD is a mental health condition characterized by difficulty maintaining attention.

Adult ADHD or Attention Deficit Hyperactivity Disorder is a mental health condition characterized by difficulty maintaining attention. Currently, it affects more than 3 million people in the United States each year.
Since the cardinal symptoms of ADHD include trouble focusing, hyperactivity, and impulsive behavior, Adult ADHD has a profound impact on life activities. Persons with this disorder report relationship difficulties and a poor work performance. They are characterized as being impulsive and having a risk-taking behavior.

Brief Account of Adult ADHD

Some problems linked to inattention include making careless mistakes, having trouble organizing activities, and losing necessary materials. Many adults attribute such difficulties to a lack of energy, forgetfulness or other issues.

These are also erroneously associated with an advancing age. Some have even engineered their lives to avoid activities requiring a high degree of focus. Other adults have underlying medical issues such as untreated diabetes or thyroid issues that make completing tasks difficult.

For these reasons, consulting with a licensed psychologist, psychiatrist, or other professionals with specialized ADHD training is of particular importance. In an adult, hyperactivity can take the form of fidgeting, interrupting during conversations, or restlessness.

Between 10% and 60% of children become adults with ADHD. Those who have this condition and are not diagnosed until adulthood must have exhibited inattentive or impulsive behavior before age 12 to receive a formal diagnosis of ADHD as an adult. Although a variety of factors, ranging from gluten sensitivity to parenting techniques, have been blamed for ADHD, a recent study has linked it to brain structure differences. This was determined by using medical imaging.

Adult ADHD is a relatively common condition that is completely treatable with talk therapy, medication or, most often, a combination approach. If you think that either a loved one or yourself are affected, you need to see a licensed specialist for screening and a possible treatment.

New Study Claims That Running Can Prolong The Life Expectancy

A new study claims that running can allegedly help prolong the life expectancy by around 3 years.

A new study claims that running can allegedly help prolong one’s life. The researchers state that only two hours of such an exercise per week can help expand one’s lifespan with about three years. Reportedly, neither the speed nor the mileages of the run will matter.

The new research was carried out by Iowa State University scientists. They published their results in the Progress in Cardiovascular Diseases. For their study, the team re-analyzed information and data gathered by previous researchers carried out at the Cooper Institute in Dallas, Texas some three years ago.

These found that running on a weekly basis for some 5 to 10 minutes every day at about less than 6 miles per hour can reduce the mortality risk by even up to 30 percent.

Running Is Reportedly Beneficial Even If Performed At A Slow, Or Rather Short Rate

Now, this new study echoes and reinstates some of the original findings and also comes with new information. For example, they found that the actual pace or mileage of a run do not actually matter. Instead, just the physical activity in itself is enough to reduce the risk of premature death. This was estimated to fall by about 40 percent.

The research team then introduced factors such as drinking, smoking, or various health problems. Nonetheless, the findings still ‘held true’ even in such cases.

Based on the previously gathered data, the team also went to establish that runners engaging in such a physical activity for 2 hours every week, could significantly expand their life expectancy. This could grow by three years or even more. Also, this would translate into less than 6 months of actual running over a 40-years period.

However, people should not expect a further addition in years, no matter how much they run. The team also stated that are as yet unsure what actually cause these benefits, or of why running can extend the life expectancy. They offered the lifestyle as a potential reason, but more research on the matter is still needed.

New Study Claims That Bed Bugs Are Becoming More Resistant

A new study went to discover the reasons why bed bugs are becoming harder to kill.

A new study went to discover the reasons why bed bugs are becoming harder to kill. According to this research, these have seemingly become more resistant to most common insecticides used to terminate them.

Research results were released earlier this week in The Journal of Economic Entomology. The study team found bed bugs have started showing a lower susceptibility to most pesticides, especially to the two most common ones. These latter are known to contain bifenthrin and chlorfenapyr.

This Is The First Study To Point Out The Increased Pesticide Resistance Of The Bed Bugs

In order to confirm their theory, the research team tested 10 bedbug species. These were collected from across several states including Virginia, Tennessee, New Jersey, and Ohio. They were also gathered from Indiana and Washington DC. Then, the researchers subjected the collected specimens to a pesticide treatment.

Also, the team used a strain known to be susceptible to these insecticides as a control group. As such, they compared the impact of bifenthrin and chlorfenapyr on the two groups. The study went to verify how long it took before their effects started to kick in.

As it is, research noted that killing the collected specimens required a higher concentration of insecticides when compared to the control group. The bugs in this latter group died three days after being exposed to bifenthrin. It also took seven days before their exposure to chlorfenapyr killed them.

However, both these time frames were stretched out in the case of the 10 test populations. These took longer to perish after being exposed to the same quantity of such pesticides. Nonetheless, the research team pointed out as follows.

These ‘pesky insects’ are not unstoppable. “[…], both bifenthrin and chlorfenapyr should be integrated with other methods used for bed bug elimination in order to preserve their efficiency in the long term.”

Parkinson Symptoms May Be Improved Through This New Method

parkinson symptoms in the brain

A new study believes to have found a new way of ameliorating Parkinson symptoms.

A new study believes to have found a way of ameliorating Parkinson symptoms. The research team considers that it may be able to do so by injecting a modified virus into a specific brain part. By doing so, they should be able to reprogram cells in order to help treat the disease.

People who have Parkinson’s disease have trouble controlling their movements. According to research, this happens as some of their dopamine-producing neurons start dying off. Dopamine is seen as a brain signaling chemical.

Now, this latest study proposes a new way of replacing such neurons. Research was carried out by a team of Karolinska Institute in Stockholm, Sweden scientists. They published their results in a paper in the Nature Biotechnology journal.

The research team, led by Ernest Arenas, tested its new method in lab tests on mice. These latter had already lost their brain’s dopamine neurons.

Parkinson Symptoms Could Reportedly Be Reduced, Even Treated, With Help From This New Method

The researchers stated that they injected the study mice with a specifically modified virus. This latter was engineered so as to carry 4 exact genes. These were used for reprogramming astrocytes which are also seen as the support cells of the brain. They were then turned into dopamine-producing neurons. Some 5 weeks later, the researchers started seeing an improvement in the way in which the mice moved.

“They walked better, and their gait showed less asymmetry than controls”. This is according to Arenas, the study lead.

The research team stated that the effects of its virus were only localized in the specific injection area. They did not notice astrocytes turning into dopamine-producing neurons in any other brain region. Also, they did not observe any adverse reactions nor did they see signs of tumors or other such counter effects.

As it is, the team stated that it would have to improve the technique and carry out careful safety checks before even trying such a technique on humans. Nonetheless, preliminary tests found that it may potentially be useful in humans as well.

A team of scientists has managed to achieve another breakthrough in the area of stem cell therapies.

A team of scientists has managed to achieve another breakthrough in the area of stem cell therapies. They were able to create totipotent stem cells in the lab. This is the first time ever to achieve such a feat and follows the creation of pluripotent stem cells.

Scientists Will Try To Develop New Stem Cell Therapies Based On Such Totipotent Cells

This new breakthrough was achieved by an international team of researchers coming from the California Salk Institute and the Chinese Peking University. Study results were published in the Cell journal. They were able to create the totipotent stem cells from both cultured mouse and human such cells.

Totipotent stem cells are known to be able to form tissues capable of providing embryonic support. At the same time, they may also offer extra-embryonic tissues, for example, the amniotic sac and the placenta.

“This is the first study reporting the derivation of a stable stem cell type that shows totipotent-like bi-development potential towards both embryonic and extra-embryonic lineages”.

This is according to Juan Carlos Izpisua Belmonte, a Salk Professor, and researcher involved in the study. The team was able to divide the new cells into either totipotent or pluripotent stem ones, while still early on in the development process.

They were able to do so thanks to a new chemical cocktail. This was able to stabilize the cells before the division process and this prolonged their versatility. As such, the researchers dubbed their result EPS cells or “extended pluripotent stem cells”.

Based on the new chemical cocktail, the team was able to create various stem cell therapies. More exactly, they were able to form chimeras or a collection of embryonic cells coming from different zygotes. According to Izpisua Belmonte, the new, totipotent-like stem cells line may have a “broad and resounding impact” in the stem study field.

New Skull Cap May Offer New Chance For Brain Tumor Patients

ness skull cap

According to a clinical trial, a new skull cap device could help improve the survival chances of brain tumor patients.

According to a clinical trial, a new skull cap device could help improve the survival chances of brain cancer patients. It could do so as it shocks the tumor with low-intensity electric fields. Nonetheless, this therapy would also have to combine with an oral chemotherapy.

The new clinical trial study results were presented at the American Association for Cancer Research annual meeting. This new skull cap device is produced by Optune and works as follows. It is capable of continuously delivering alternating electric fields to the affected brain part. According to the researchers, this can have an anticancer effect as it helps block cell division.

This New Skull Cap Could Improve And Prolong Glioblastoma Survival Rates

The trial study involved patients diagnosed with the aggressive cancer type named glioblastoma. For the trial, they were randomly assigned to one of two treatment methods. A first was based on the Optune skull cap combined with a chemotherapy treatment. The other offered solely the chemo method.

Then, the research team monitored the patients and reported their median overall survival rates. Those that used the Optune cap had a 21-months such rate. In contrast, chemo-only patients had a 16-months median overall survival one.

Median survival rates presented, in general, an overall improvement even on the 1 to 5-years time frame. After a year, the team reported a 43 percent cap survival rate, compared to 31 percent for patients with just chemo. 5 years later, the percentages had fallen to 13 percent versus 5 percent, but the Optune results still stand.

 “Now, we see a meaningful improvement in survival at two years and beyond. With the combination of Optune a temozolomide, one out of seven patients is living longer than 5 years.”

This is according to Dr. Roger Stupp, a Neurological Surgery Professor part of Northwestern University.

Reportedly, There Are Over 20 Million Physically Inactive Britons

physically inactive people

A new study found that over 20 million people living in Britain are quite physically inactive.

A new study went to analyze the lifestyle choices of British people. According to it, over 20 million people living in Great Britain are quite physically inactive, which could come with serious risks to their health. The study and report come from the British Heart Foundation or BHF, a charity organization based in the United Kingdom.

According to the researchers, they considered ‘physically inactive’ any person which did not follow the governmental health guidelines. These state that every individual should accomplish 150 minutes of physical activity each week. This doesn’t even have to be intense, it can have a moderate intensity. Also, they should perform strength activities at least every two days throughout a week.

The BHF found that women are more likely to be physically inactive than men. More exactly, they are 36 percent less active which accounts for some 11.8 million people, compared to 8.3 million men.

The Rates Of Physically Inactive Also Varied According To Region

In its report, the charity also presented a list with the least activity regions in the United Kingdom. North West England residents placed first, with a 47 percent rate of inactivity. They were followed by the Northern Ireland population with 46 percent and the Welsh with 42 percent. North East England and London residents rounded up the top 5 less active.

According to the BHF, this lack of physical activities poses more risks than initially believed. The charity claims that it leads to over 5 million deaths each year at a worldwide level. Exercising regularly is recommended as it can help reduce the risk of circulatory problems and heart disease. This can be reduced by as much as 35 percent. The early death risk can also see a significant reduction thanks to regular exercises, one of up to 30 percent.

Deep Breaths Help Us Calm Down

deep breaths

Deep breaths are the ones that calm our brain activity.

Remember when you were so angry that you wanted to punch somebody. When you feel that way the best thing you can do to calm down is to take deep breaths. A new research shows that deep breaths can calm your nerves in a few seconds.

This new study focused on showing the effects of deep breathing when it comes to our feeling. In order to conduct this study, researchers analyzed mice. They observed a connection between the nerve cells and breathing. Deep breaths were the ones that calmed the brain activity.

Less than 400 nerve cells are responsible for the connection between our brain activity and breathing. Once the researchers removed those nerve cells from the mice they observed that the mice were very calm and that they breathed normally.

Scientists mentioned that their research could, someday, help people that suffer from panic attacks, anxiety, and stress. Their findings were published in the journal Science. Breathing is involuntary, an unconscious action that we do in order to stay alive. Animals and human inhale oxygen and exhale carbon dioxide after they used the oxygen to create energy.

People have been taking deep breaths when they feel angry or anxious for a long time. This research just showed the connection between the activity of the brain and deep breaths. Panic attacks, for instance, make a person to take fast, short breaths. This causes the person to feel even more panicked.

This research was conducted by scientists from Stanford University School of Medicine. They observed that our breathing can control the way we feel. When we are angry we tend to breathe faster and to inhale less oxygen. The interesting fact is that the brain is the ones that control the breathing. So, if we manage to make our brain to control the breathing in such a way for us to take deep breaths in the moments when we feel angry, we are more likely to calm down easily.

The problem is that people who suffer from a panic attack have a hard time controlling their breathing. Despite this fact, people who suffer from anxiety should consider doing this simple “treatment”. Deep breaths can make a person feel calm and relax in almost any situation.

What is your opinion about this study? Did you ever use this method of calming down?
