Attacking the brain

Stroke kills more women than men each year but there are preventive steps you can take to minimise your risks.



IN Malaysia, strokes are the third leading cause of death for women, following heart attacks and pneumonia.

For some unknown reasons, many women choose not to join a post-stroke rehabilitation programme.

It is more deadly to women than breast cancer, and if it doesn’t kill you, can leave you with permanent disabilities.

A stroke is sometimes known as a “brain attack.”

It occurs when blood flow to a part of the brain is blocked by a blood clot or plaque, and brain cells begin to die.

Here are some facts about how strokes affect women differently from men:

> More women have strokes later in life.

> After age 85, stroke affects many more women than men.

> It is twice as common for women between 20 and 39 to have a stroke compared to men of the same age.

> Having a history of problems during pregnancy like gestational diabetes or preeclampsia.

> Using hormonal birth control while smoking.

> Being on menopausal hormone therapy during or after menopause.

> Experiencing migraines with aura, atrial fibrillation (irregular heartbeat), and diabetes.

Many strokes are preventable and treatable.

By knowing your risk factors and making healthy changes, you can minimise your risks of experiencing a stroke.

Three types of stroke

Ischemic stroke is the result of blockage of blood flow to the brain. This is the most common type of stroke, and it happens most often when a person has a blood clot or atherosclerosis, a condition when an artery is clogged with plaque

Hemorrhagic stroke, caused by bleeding into the brain.

This type of stroke happens when a blood vessel in the brain bursts, and blood bleeds into the brain.

An aneurysm, which is a thin or weak spot in an artery that can burst, is responsible for this type of stroke.

Mini-stroke, also called a transient ischemic attack or TIA, can happen when, briefly, less blood than normal flows to the brain.

TIA usually lasts only a few minutes or up to several hours. Many people aren’t even aware that they had a stroke.

Stroke affects different parts of the brain, and depending on which part, you may experience problems with speech, movement, balance, vision or memory.

Division of brain

The brain is divided into four main parts: right hemisphere; left hemisphere; the cerebellum; which controls balance and coordination; and the brain stem, which controls all of our body’s functions that we don’t think about, such as heart rate, blood pressure, sweating and digestion.

A stroke can happen in different parts of the brain.

In the right half of the brain, a stroke can cause:

> Mobility issues on the left side of your body.

> Problems with misjudging distances. This can cause falls, or inability to guide your hands to pick something up.

> Short-term memory loss. You may be able to remember events from 10 years ago, but may forget the directions to your regular grocery store.

> Misjudgement of abilities to do things and unusual behaviour such as leaving your house without getting fully dressed.

In the left half of the brain, a stroke can cause:

> Mobility issues on the right side of your body.

> Difficulty completing everyday tasks quickly.

> Trouble speaking or understanding others.

> Memory problems, or a tough time learning new things.

In the cerebellum, a stroke can cause:

> Dizziness, nausea (feeling sick to your stomach), and vomiting.

> Stiffness and tightness in the upper body that can cause spasms or jerky movements.

> Balance problems.

> Eye problems, such as blurry or double vision.

In the brain stem, strokes are most harmful.

Impulses that start in the brain must travel through the brain stem on their way to the arms and legs, so individuals that suffer a stroke in the brain stem may also develop paralysis.

Beware of these symptoms

Some women are more at risk because of certain health problems, family health history, age and habits. These are called risk factors.

There are certain risk factors that cannot be changed, such as age, race or ethnicity, or family history. The only thing that you can do is to control other stroke risk factors, such as high blood pressure, diabetes, smoking and unhealthy eating.

Common symptoms of stroke include:

> Trouble seeing in one or both eyes.

> Severe headache with no known cause.

> Trouble walking, dizziness, or loss of balance or coordination.

> Numbness or weakness of face, arm, or leg, especially on only one side of the body.

> Confusion or trouble speaking or understanding.

Recovering from stroke

The process of recovery can take a lot of time and depends on many factors, like the type of stroke you had, the area of your brain affected, and the amount of brain injury.

Recovery begins once you are medically stable, and this is within a day of suffering the stroke.

Your next steps will involve changes in everyday habits, medicines and rehabilitation.

In some cases, surgeries may be needed to lower the risk of another stroke.

The first step is to learn about your condition and what you should do during recovery.

Your doctor, nurses and physical therapist can answer questions you may have about about the treatment and rehabilitation.

The next critical step is to take steps to prevent another stroke from happening.

Stroke patients are always at a higher risk of having another down the road, so you need to:

> Identify and control your personal risk factors.

> Be consistent with your treatment plan. It is designed to help you recover from your stroke and prevent a recurrence.

> Continue taking medications even if you feel better. Discuss with your doctor before making changes. Also, determine the rehabilitation services you will need.

For unclear reasons, many women do not join a post-stroke rehabilitation programme.

After a stroke, you will often recover some function in the first few months. This is part of the body’s natural healing process.

But women who do go to stroke rehabilitation reap the following benefits:

> Regain as much independence as possible.

> Relearn skills and abilities that were damaged or lost.

> Learn to cope with any remaining limitations.

Setting a goal
Settling a goal can motivate you to measure your progress - TNS
Another important step is to set goals for your recovery.

You need to set realistic and measurable goals for recovery in every area of your life that has been affected.



Stroke recovery may be fast in the first few months, but it may slow down eventually.>>

When you set goals, it can motivate you to maintain progress.

Create a timeline for achieving long-term goals.

Take a multi-step approach for each goal and celebrate the short term wins when you gain them. And finally, don’t give up! The aftermath of a stroke can make patients feel powerless.

Part of your recovery is determining how to live as independently as possible.

Be reasonable with yourself, and be prepared to face challenges as you adapt to the differences in how your body works.

The road to stroke recovery may not be easy, but by focusing on celebrating your progress at every step, you can reach your goals.

Ensure you also have adequate nutrition and nutritional supplements to expedite the healing and recovery process.

The U.S. hit another grim milestone on Thursday as thee number of total confirmed cases of COVID-19 passed four million, with data showing it only took 16 days to go from three million to four million, with the average number of new cases now rising by more than 2,600 every hour. Deaths are also increasing, with Florida and Texas each reporting record one-day increases in the number of new deaths.

Trump has 100 days to save his US presidency

Donald Trump has 100 days from Sunday to save his presidency, while the US tries to avoid a collective nervous breakdown ahead of one of the most divisive, tension-filled elections in US history.

Coronavirus is ravaging the economy, adding to a death toll already above 140,000, while undermining national trust in government institutions.

Add explosive protests against racism and police brutality, leftist-led riots, flourishing right-wing conspiracy theories and the spectre of Russian meddling — and you have a country more on edge than at any time since the cataclysmic 1960s.

At the centre is Trump, a man who boasts he never tires of “winning” yet faces possible humiliation on November 3.

Democratic challenger Joe Biden, whom Trump derides as weak and mentally incompetent, leads by double digits in some polls.

Trump is 74, Biden 77 — a matchup of two elderly white men seemingly out of step with 2020s uprisings against racism and sexism.

One is a billionaire born into privilege; the other, with three decades in the Senate and two terms as vice-president under Barack Obama, the epitome of the professional politician.

Trump vs Biden will deliver all the upheaval a confused US electorate can stomach.

Trump’s pitch boils down to claiming Biden will have Americans “cowering to radical left-wing mobs”. Biden says he’s fighting for “the soul of America”.

On Thursday, Trump cancelled the traditional Republican convention planned in Florida in August due to coronavirus concerns.

The Democrats scrapped theirs weeks ago.

Polls give Biden an advantage nationally and strong leads in swing states.

Congressional Democrats, who already control the House, are eyeing recapture of the Senate.

Many incumbents in Trump’s predicament might at this point start planning their post-presidential libraries.

Trump presides over mass unemployment triggered by the coronavirus shutdown, racial unrest and a growing crisis of confidence.

On coronavirus, polls show two-thirds of Americans have no faith in his leadership.

Trump, with approval ratings stuck in the low 40% range, is the first president to seek re-election after impeachment.

Yet no-one counts him out.

Belittled in 2016, he defeated all the top Republican establishment names for the nomination, then came from behind to defeat Hillary Clinton.

Trump believes he still has the secret sauce.

“I’m not losing, because those are fake polls,” he insisted last weekend.

“They were fake in 2016 and now they’re even more fake.”

Biden is running his campaign from his Delaware home, with no rallies, few media interviews and even rarer press conferences.

Biden is able to sit back and watch Trump lurch ever deeper into self-inflicted troubles.

Until the onset of Covid-19 and the economic downturn, Trump was on a roll.

His then confident campaign manager Brad Parscale described the Republican re-election team in May as the “Death Star” in the Star Wars movies and tweeted they were about to press the “fire” button.

Today, that vaunted machine resembles a misfiring rocket.

Trump’s mass rallies have fizzled due to health risks, while his trademark bravado and name-calling sit less easily in a country shaken by death and economic misery. — AFP

China's Long March-5 Y4 carrier rocket, carrying the Mars probe, blasted off at 12:41 p.m., July 23, 2020, from Wenchang Spacecraft Launch Site in south China's Hainan Province.

2020 can be regarded as the year of Mars. Following Sunday's launch of the UAE's Mars probe, China inaugurates its first Mars exploration mission Tianwen-1 in Wenchang Space Launch Center in southern Hainan Province. After the launch via a Long March-5 carrier rocket, the Mars probe will conduct a series of tasks and explorations on the red planet.

China successfully launched its first Mars probe, named Tianwen-1, via a Long March-5 Y4 carrier rocket from Wenchang Space Launch Center in South China's Hainan Province into planned orbit on Thursday. The move heralds a new era in China's deep-space exploration, which has steadily progressed beyond moon probes to interplanetary missions, mission commanders and developers said.

After a flight of around 2,000 seconds, the probe entered the planned Earth-Mars transfer orbit, officially embarking on its journey to the Red Planet, according to the China National Space Administration (CNSA)on Thursday.

China's Tianwen-1 Mars probe is expected to reach Mars' gravity field in February 2021, about seven months after the launch. If it succeeds, Tianwen-1 will be the first Mars expedition to complete orbiting, landing and roving in a single mission in humanity's history.

According to the CNSA, the project is set to achieve a series of technological advances, including Mars orbit insertion, long-term automatic probe management, long distance communication and Mars surface roving capabilities.

The interplanetary mission will also mark China's establishment of a complete deep-space exploration project system, covering design, production, flight mission and scientific research.

The mission also involves international cooperation, as the European Space Agency and Argentina will participate by taking part in spacecraft monitoring and controlling, the Global Times has learned from the CNSA.

Moreover, China is also working with countries including France and Austria on payload scaling and data analysis for the mission.

The Thursday launch mission was the fifth flight of the Long March-5 carrier rocket series, the strongest member of China's launch vehicle family. The last launch mission of the Long March-5B, a smaller variant of the Long March 5, took place on May 5, also from the Wenchang Space Launch Center in Hainan.

The Thursday launch also marked the first time the Long March-5 was put to practical mission use, the rocket developer China Academy of Launch Vehicle Technology (CALT) under the state-owned space giant China Aerospace Science and Technology Corporation (CASC) told the Global Times on Thursday.

"The completion of the first practical mission would indicate that the Long March-5 series has officially joined service," Wang Jue, chief commander of the Long March-5 rocket model, told the Global Times.

Long March-5 has a 5-meter diameter core stage and four 3.35-meter diameter boosters, and is 57 meters long with a take-off weight of around 870 tons and thrust of 1,000 tons. It has raised the country's Geostationary Transfer Orbit (GTO) launch capability from 5 tons to 14 tons.

The Long March-5 Y4 carrier rocket has reached an escape velocity of over 11.2 kilometers per second, managing to send the probe into planned orbit, and according to Li Dong, chief designer of the Long March-5, "this speed set a new fastest flight speed record for China's launch vehicles."

The Tianwen-1 Mars probe, which weighs about five tons, is also the heaviest deep space probe that China has ever sent into space, and is one ton heavier than the Chang'e-4 lunar probe, which China successfully sent to the dark side of the moon in January 2019, the CALT noted.

The powerful launch capability of the Long March-5 rocket has advanced the country's deep-space exploration to a new starting point in interplanetary expeditions, and a new era of planet probes beyond the moon has officially been ushered in as the first Mars probe begins, Li Minghua, CALT's Party chief, announced upon the successful launch on Thursday.

The Long March-5 carrier rocket is expected to launch another Chang'e-5, weighing about eight tons, which aims to undertake the country's first moon sample return mission, set to take place before the end of this year. The Long March-5B will launch the core module of the country's first space station around March 2021, Lou Luliang, the rocket series vice chief designer, revealed to the Global Times.

Challenges ahead


Mars, one of Earth's closest neighbor planets in the solar system, has the most similar environment to Earth's. Human beings have made 44 Mars mission attempts, and only 24 of them succeeded.

The minimum distance between Mars and Earth is about 55 million kilometers, and the two planets only come that close every 26 months. The Mars exploration window is open between July and August.

No country other than China has ever set the goals of orbiting, landing and roving the Red Planet in its first mission attempt, and the successful launch will only mark the beginning of a long expedition full of challenges, and uncertainties also remain, observers noted.

According to the CASC on Tuesday, only a handful of Mars missions have been able to land on the planet and conduct roving explorations.

China's Mars orbiter will carry seven scientific payloads, while the rover will have six, according to the CASC. Safely landing the Mars rover after the probe enters the planet's orbit, which will take around seven minutes, will be one of the most decisive stages of the whole mission. During those seven minutes, the probe needs to slow down from more than 20,000 kilometers per hour to zero, which poses a grave challenge to its surface heat-resistance capability.

To overcome that, CALT has developed a new material structure, which is more advanced than that for the US Apollo flight, to ensure the safety of the probe in the deceleration process.

Besides China, the US and the UAE are also launching their Mars missions this summer.

The first Arab space mission to Mars, an unmanned probe dubbed Hope, blasted off from Japan on Monday, in a bid to reveal more about the atmosphere of the Red Planet.

NASA moved its first launch attempt of its Mars 2020 mission to no earlier than July 30, according to the US space agency's official website.

ExoMars, a cooperation program between Europe and Russia, earlier announced that it will be delayed to 2022.

Who's next? US closing Chinese consulate worries people on both sides

Whether it is Chinese people in Houston or US citizens in China, they all expressed concerns about the US abruptly demanding China close its Consulate General in Houston on Wednesday, worrying they will be the next target of the Trump administration as leverage to further contain China. 

US cannot get away from China's countermeasures against consulate closure

Will China retaliate against the US for abruptly ordering China to close its consulate in Houston? How will China strike back to such action? Reuters reported that China is considering shutting down the US consulate in Wuhan. It is very likely that the news agency is wrong this time.
