Media coverage of disasters can have lasting effects on children’s mental health

In 2018, American children have been exposed to multiple disasters—ravaging wildfires in California, to major Hurricanes in Florida and the Carolinas, and mass shootings in schools and places of worship—all of which have been covered 24/7 by the media. Disaster communication experts at the University of Missouri say disaster media coverage can have lasting effects on children’s mental health and suggest teachers and parents be prepared to respond to questions during and after a catastrophe.

Researchers in the MU Disaster and Community Crisis Center found that teachers and parents might not be prepared to respond to students’ questions and anxieties in the aftermath of natural or human-caused disasters. The coverage can impact children’s mental health, not only in school but in response to future disasters as well.

“Teachers spend seven to eight hours a day with children,” said Jennifer First, program manager at the Disaster and Community Crisis Center and a doctoral candidate in the MU School of Social Work. “They often are the first responders, both directly and indirectly.”

The Disaster and Community Crisis Center developed a step-by-step plan with guidelines on how to discuss disasters with children. They found that teachers commonly don’t know how to answer children’s questions about disasters such as mass shootings or devastating wildfires, or explain why they happen at all.

“Images of disasters stay with kids for a long time,” First said. “That’s why it’s important to be prepared and offer helpful coping methods.”

The researchers surveyed 42 teachers on their preparation in dealing with media coverage of disasters. They also were asked what techniques they felt were needed to help students in dealing with their fears and anxieties. First and her colleagues found that many children bring concern to teachers and parents about why these terrible things happen and what can be done to stop it happening to them. The Disaster and Community Crisis Center includes instructions in their disaster intervention protocols about encouraging safety measures and helping victims. The detailed instructions can be found on their website.

Chemo-brain IS real: How cancer treatment causes mental fog

Chemo-brain IS real: Scientists discover how cancer treatments damage white matter to cause mental fog

  • More than half of cancer patients treated with chemo experience brain fog 
  • ‘Chemo-brain’ is a recognized phenomenon, but poorly understood
  • Stanford University researchers found that chemo affects three types of cells in the white matter 
  • They also discovered that a drug that may block and reverse these effects 

Scientists have finally begun to work out what exactly ‘chemo-brain’ is – and may have found a way to reverse the brain fog cancer treatment cause, a new study reveals. 

More than half of patients that receive chemotherapy report experiencing a cognitive fog for months and sometimes years after undergoing the intensive cancer treatment, but doctors haven’t really understood what causes this. 

A team of Stanford University scientists, however, have identified chemo’s effects on three different types of brain cells. 

They think that chemo causes a sort of arrested development for some brain cells and blocks the activity of cells that help ensure our brain cells are well-fed with nutrients because the drug triggers an overly-active immune response. 

In their experiments on mice, a drug to quell those immune cells helped to reverse chemo’s cognitive effects, giving the team hope that a treatment could be on the horizon.  

More than half of cancer patients who undergo chemotherapy experience ‘brain-fog.’ A new study reveals how the drug affects three types of brain cells – and a potential way to reverse it

The advent of chemotherapy was a revolution in the treatment of cancer.

Around the time of World War II, the US military’s tests of mustard gas led to the discovery that compound based on mustard gas could combat some cancers. 

Soon thereafter, the predecessor to the now commonly-used methotrexate was discovered. 

Tumors grow when a DNA mutation allows cells to divide and multiply out of control. But methotrexate’s predecessor blocked that DNA from replicating, so it blocked cancer growth, too. 

Chemo’s roots in poisons and warfare are telling. Any chemotherapy is toxic to us – it’s just most toxic to carcinogenic cells.   

And our body responds accordingly. chemo often makes patients nauseous, unable to eat, makes them achy and tired and makes their hair fall out.

Most worryingly to many cancer patients, chemo often comes with a decline in cognitive function that can last far longer than the treatments – or even the cancers, in some cases – themselves do. 

Chemo-brain was once dismissed as a wive’s tale. 

Even the world-renowned Mayo Clinic still calls the term ‘misleading’ and says that it is ‘unlikely that chemotherapy is the sole cause of concentration and memory problems in cancer survivors. 

We are at last beginning to understand what role it does play, however. 

The Stanford researchers focused on the neuron-supporting brain cells in the white matter. 

Three particular types seemed implicated in chem-brain: oligodendrocytes, astrocytes and microglia. 

Oligondendrocytes produce myelin, the coating that protects neurons. If these sheaths are damaged incomplete or missing, signals sent between brain cells are liable to interference. Like a radio, the signals might not come through clearly – or at all. 

Astrocytes lay important supporting roles for neurons, making sure that they are running smoothly and getting sufficient nutrition. 

And microglia are the brain’s own personal immune system. 

The researchers gave some mice with cancer chemotherapy, and left the others untreated.   

In the brains of those who had had chemotherapy, the myelin-producing cells never reached maturity, so they couldn’t produce sufficient myelin to protect the neurons. 

As a result, the mice moved more slowly, and had a harder time recalling elements of an environment that should  have been familiar to them. 

Even when they were injected with cells that would become oligondendrocytes from healthy mice, the cells got stuck in a state of arrested development in the chemo-treated mice’s brains, suggesting it was something about the toxicity of the brain environment that was interfering with this process. 

On the other hand, chemo seemed to supercharge the brain’s immune cells. The microglia were ‘persistently activated’ for at least six months after chemo was administered. 

They were on the defensive, behaving as if there was an infection or other pathogen to fight off, which likely meant prioritizing defensive action over other functions like nutrition. 

Indeed, the overactivity in the microglia interfered with the astrocytes, and the neurons struggled to get enough nutrition, which could be an additional cause of brain-fog. 

Remarkably, the Stanford researchers discovered that they could use a drug that attacked the microglia to restore the balance between them and the nutrient-feeding cells – reversing the cognitive effects of the chemo. 

‘The biology of this disease really underscores how important intercellular crosstalk is,’ lead study author and Stanford neurologist Dr Michelle Monje said. 

‘In addition to existing symptomatic therapies – which many patients don’t know about – we are now homing in on potential interventions to promote normalization of the disorders induced by cancer drugs. 

‘There’s real hope that we can intervene, induce regeneration and prevent damage in the brain.’

Rates of Mental Health Tx, Diagnosis Up for College Students

FRIDAY, Nov. 16, 2018 — From 2007 to 2017, there was an increase in the rates of mental health treatment and diagnosis among college students and a decrease in stigma, according to a study published online Nov. 5 in Psychiatric Services.

Sarah Ketchen Lipson, Ph.D., Ed.M., from the Boston University School of Public Health, and colleagues used 10 years of data from the Healthy Minds Study, which included 155,026 students from 196 campuses, to examine mental health service utilization by college students.

The researchers observed significant increases in the rates of mental health treatment and diagnosis. From 2007 to 2017, the rate of treatment increased from 19 to 34 percent, and an increase from 22 to 36 percent was seen in the percentage of students with lifetime diagnoses. Increases were also seen in depression and suicidality, while there was a decrease in stigma.

“We found that utilization increased substantially over the past decade, with much of this burden falling to campus counseling centers,” the authors write. “To better meet the mental health care demand from students and reduce strain on existing services, campuses may wish not only to expand capacity but also to increase the use of preventive and digital mental health services, such as those delivered via mobile apps.”

One author disclosed receiving consulting fees from Actualize Therapy.
