Magic Mushrooms can ‘Reset’ Depressed Brain

A hallucinogen found in magic mushrooms can “reset” the brains of people with untreatable depression, raising hopes of a future treatment, scans suggest.

The small study gave 19 patients a single dose of the psychedelic ingredient psilocybin.
Half of patients ceased to be depressed and experienced changes in their brain activity that lasted about five weeks.

However, the team at Imperial College London says people should not self-medicate.

There has been a series of small studies suggesting psilocybin could have a role in depression by acting as a “lubricant for the mind” that allows people to escape a cycle of depressive symptoms.
But the precise impact it might be having on brain activity was not known.

The team at Imperial performed fMRI brain scans before treatment with psilocybin and then the day after (when the patients were “sober” again).

The study, published in the journal Scientific Reports, showed psilocybin affected two key areas of the brain.

  • The amygdala – which is heavily involved in how we process emotions such as fear and anxiety – became less active. The greater the reduction, the greater the improvement in reported symptoms.
  • The default-mode network – a collaboration of different brain regions – became more stable after taking psilocybin.

Dr Robin Carhart-Harris, head of psychedelic research at Imperial, said the depressed brain was being “clammed up” and the psychedelic experience “reset” it.

He told the BBC News website: “Patients were very ready to use this analogy. Without any priming they would say, ‘I’ve been reset, reborn, rebooted’, and one patient said his brain had been defragged and cleaned up.”

However, this remains a small study and had no “control” group of healthy people with whom to compare the brain scans.

Further, larger studies are still needed before psilocybin could be accepted as a treatment for depression.

However, there is no doubt new approaches to treatment are desperately needed.

Prof Mitul Mehta, from the Institute of Psychiatry at King’s College London, said: “What is impressive about these preliminary findings is that brain changes occurred in the networks we know are involved in depression, after just a single dose of psilocybin.

“This provides a clear rationale to now look at the longer-term mechanisms in controlled studies.”

The Best Way To Stop Depression From Recurring

Depression frequently recurs but therapy and drugs are not the only answers.

Seeking out social relationships may help people to recover from depression.

Building a social support system helps people stay depression-free.

In addition, people who find activities they enjoy recover better from depression.

By contrast, people who are aggressive loners are at a heightened risk of depression recurrence, research finds. Those who do not seek out social relationships find it harder to recover from depression.

Aggression can also make it difficult to for these type of people to heal.

Dr Jackie Gollan, the study’s first author, said:

“Depression is a recurrent disease for a lot of people just like cancer.
People who receive cognitive behavioral psychotherapy for depression tend to feel less depressed when they complete it.
However, other factors in their lives beyond their mood need to be identified if we are to help them stay well.
We need to consider who people are and how they interact with others to understand how patients remain nondepressed.”

Somewhere between 50% and 80% of people successfully treated with therapy experience a relapse within two years.

Dr Gollan explained how moderate dependency on others may help people recover:

“Low dependency increases risk for relapse while moderate dependency encourages recovered patients to seek out social relationships that may function, over time, to reduce relapse risk.”

The research followed 78 people whose depression was successfully treated with therapy and followed them over two years.

44% of people relapsed, but people with no social support system were most at risk.

Dr Gollan explained that more aggressive people were also more likely to relapse…

“…perhaps because they don’t make good friends and turn off people.
In their professional careers they have channeled aggression in productive, socially acceptable ways to their advantage and use people to their advantage.
They also are pathologically independent and independence may be a risk factor if you have depression.”

Dr Gollan said finding enjoyment was the key to recovery:

“We need to focus on how the activities feel.
We don’t know why, but it is becoming clear that people are less at risk for relapse when they do things they enjoy rather than working on overcoming their negative thinking patterns.
The treatment should be tailor-made to the depressed patient.”

The study was presented at the annual meeting of the Association for Advancement of Behavior Therapy in Toronto in 1999 (Gollan & Jacobson, 1999).

This Social Media Behaviour Triples Depression Risk

Depression and anxiety risk much higher in some people using social media.

Using over seven different social media platforms is linked to a tripling in depression risk, psychological research finds.

The study asked about the 11 most popular social media platforms: Facebook, YouTube, Twitter, Google Plus, Instagram, Snapchat, Reddit, Tumblr, Pinterest, Vine and LinkedIn.

Those who used between 7 and 11 of these, had 3.1 times the depression risk.

They also had 3.3 times the risk of having high levels of anxiety symptoms.

Professor Brian A. Primack, who led the study, said:

“This association is strong enough that clinicians could consider asking their patients with depression and anxiety about multiple platform use and counseling them that this use may be related to their symptoms.
While we can’t tell from this study whether depressed and anxious people seek out multiple platforms or whether something about using multiple platforms can lead to depression and anxiety, in either case the results are potentially valuable.”

There are a number of ways in which using multiple platforms might lead to depression and anxiety, the authors argue:

  • Multitasking is known to lead to poor mental health and weakened thinking skills.
  • Using more platforms might lead to more opportunities for embarrassing mistakes.

Professor Primack said:

“It may be that people who suffer from symptoms of depression or anxiety, or both, tend to subsequently use a broader range of social media outlets.
For example, they may be searching out multiple avenues for a setting that feels comfortable and accepting.
However, it could also be that trying to maintain a presence on multiple platforms may actually lead to depression and anxiety.
More research will be needed to tease that apart.”

The results come from a 2014 survey of 1,787 US adults aged between 19 and 32.

How To Deal With Negative Thoughts And Anxiety

People in the study were asked to journal about their most stressful experiences.

Accepting negative emotions is the best way to deal with them in the long-run, new research finds.

People who are more accepting of their darker moods have better psychological health.

Dr Iris Mauss, one author of the study, said:

“We found that people who habitually accept their negative emotions experience fewer negative emotions, which adds up to better psychological health.”

Psychologists are still not sure exactly why acceptance is so powerful, said Dr Mauss:

“Maybe if you have an accepting attitude toward negative emotions, you’re not giving them as much attention.
And perhaps, if you’re constantly judging your emotions, the negativity can pile up.”

The results come from research on over 1,300 people.

Those who most strongly resisted negative emotions, or judged them excessively, were more stressed.

Over six months, the people who did best were those who let their dark moods run their course, with little judgement or criticism.

They had fewer symptoms of mood disorders like depression.

Dr Brett Ford, the study’s first author, said:

“It turns out that how we approaach our own negative emotional reactions is really important for our overall well-being.
People who accept these emotions without judging or trying to change them are able to cope with their stress more successfully.”

The researchers ruled out being richer as a factor, Dr Mauss said:

“It’s easier to have an accepting attitude if you lead a pampered life, which is why we ruled out socio-economic status and major life stressors that could bias the results.”

People were asked to journal about their most stressful experiences, in one of three studies the researchers conducted.

In general, those who did not feel bad about feeling bad had the highest levels of well-being and psychological health.

Next, the researchers want to look at where the habitual acceptance of negative emotions comes from.

Dr Mauss said:

“By asking parents about their attitudes about their children’s emotions, we may be able to predict how their children feel about their emotions, and how that might affect their children’s mental health.”

The study was published in the Journal of Personality and Social Psychology (Ford et al., 2017).

Does Too Much Sugar Lead to Depression?

Previous studies have shown that sugar can be just as addictive as cocaine, but recent research suggests the sweet stuff may not be doing any favours for our mental health, either.

According to a recent report by the University College London, published in the Scientific Reports journal, men who consumed a high intake of sweet food and drinks were more likely to develop common mental health disorders like anxiety and depression after five years.

“Our research confirms an adverse effect of sugar intake from sweet food/beverage on long-term psychological health and suggests that lower intake of sugar may be associated with better psychological health,” researchers wrote.

Looking into the research

To find patterns between eating sugar and developing mental health disorders, civil participants in the U.K. were monitored between 1985 to 1988, and then were asked to filled out questionnaires ever few years until 2013. The experts studied more than 8,000 people, but a majority of them (around 5,000) were men.

Researchers noted men who consumed more than 67 grams of sugar a day had a 23 per cent increased chance of experiencing a mental health disorder — compared to those who ate less than 39.5 grams per day, the Guardian reports.

But the study has also received some criticism, including the fact that consumption was self-reported, and sugar intake from alcohol was not included.

“The dietary analysis makes it impossible to justify the bold claims made by the researchers about sugar and depression in men,” dietitian Catherine Collins, a spokeswoman for the British Dietetic Association, told AFP. “Reducing intake of free sugars is good for your teeth, and may be good for your weight, too. But as protection against depression? It’s not proven.”

 

A new study claims high sugar intake
can lead to depression and anxiety among men.

But previous research also points to similar results — sugar was not good for your mental health. One 2004 report published in the National Center for Biotechnology Information found a high intake of refined sugar and dairy increased the risk of depression and was even worse for people who had schizophrenia, Psychology Today reports.

The site adds The Standard American Diet, which is full of fat and sugar, didn’t increase the likelihood of developing anxiety but made anxiety symptoms in individuals worse.

Digging deeper into sugar

Abby Langer, a Toronto-based registered dietitian, says we should take studies like these with a grain of salt.

“[There are] always limitations with a questionnaire,” she tells Global News. “Depression is subjective and the reporting could be subjective.”

She adds the study also didn’t look at the consumption of straight sugar. She says if participants were mostly eating sugary foods, it could have also been the saturated fat, for example, affecting their mental health. “[Research has shown] people who are mentally ill tend to eat more sugar, there is a link for sure, but this study doesn’t prove that sugar is the cause.”

Langer argues instead of focusing so much on sugar, a highly processed diet high in sugar and refined carbs can result in low energy levels. “A diet high in protein, veggies and fruit can help your energy levels,” she says.

Cutting back on sugar this summer

And while criticisms of this particular study doesn’t mean you should load up on sugar, Langer says summer can be a tricky time to limit consumption.

“It is very important to avoid sweetened beverages,” she says. “I know you may want Gatorade, but if you aren’t running a marathon, you don’t need it.”

Iced hot drinks (think iced coffees) and the increased consumption of alcohol during warmer months, can also add up in the long-run. And instead of reaching for ice cream or another trendy summer dessert, opt for seasonal fruit instead.

“Just have frozen desserts less often,” she continues. “Limit the treats to once or twice a week.”

This Mineral Fights Depression — And It Is Cheaper And Safer Than Drugs

The supplement starts to take effect after only two weeks, the researchers found.

Over-the-counter magnesium is a safe and effective way to treat mild to moderate depression, a new study suggests.

The mineral magnesium has already been linked to lower inflammation and improvements in depression.

Now a new randomised controlled trial has tested the effects of magnesium chloride supplements compared with no treatment.

For the research, half of 126 people with mild to moderate depression were given 248 mg of magnesium chloride per day for six weeks.

After just two weeks, some positive effects of the supplement could be seen.

Those taking magnesium had clinically significant improvements over the six weeks.

People did not have any problems taking magnesium and there were no differences based on sex, age, whether people were also taking antidepressants, or other factors.

More than half of the people in the study said they would continue to take magnesium to help them with their depression.

Ms Emily Tarleton, the study’s first author, said:

“This is the first randomized clinical trial looking at the effect of magnesium supplementation on symptoms of depression in U.S. adults.
The results are very encouraging, given the great need for additional treatment options for depression, and our finding that magnesium supplementation provides a safe, fast and inexpensive approach to controlling depressive symptoms.”

Ms Tarleton says that the next stage is to move on to larger populations to see if the results can be replicated.

While many more studies have investigated antidepressant medications, there is also much evidence of their side-effects.

A survey of people taking antidepressants has found higher than expected levels of emotional numbness, sexual problems and even suicidal thoughts associated with the medication.

Of the 20 adverse effects to antidepressants that people were questioned about:

  • 62% said they had ‘sexual difficulties’,
  • 52% said they ‘didn’t feel like themselves’,
  • 42% noticed a ‘reduction in positive feelings’,
  • 39% found themselves ‘caring less about others’,
  • and 55% reported ‘withdrawal effects’.

The study was published in the journal PLOS ONE (Tarleton et al., 2017).

Depression: This Tiny Change to Diet Has Protective Effect

This small change to your diet could be enough to reduce the risk of depression.

A Mediterranean diet including fruits, vegetables and legumes can prevent depression, a large new study finds.

People only had to make relatively small changes to see the benefits.

The scientist think that depression could be partly down to a lack of essential nutrients.

The study included 15,093 people who were followed over 10 years.

People who reported eating more nuts, fruits and vegetables were considered to be following the Mediterranean diet more closely.

Those who ate more meats and sweets were considered to be moving away from the healthy diet.

The benefits of the diet are likely related to higher levels of omega 3 and other essential nutrients.

Dr Almudena Sanchez-Villegas, who led the research, said:

“We wanted to understand what role nutrition plays in mental health, as we believe certain dietary patterns could protect our minds.
These diets are all associated with physical health benefits and now we find that they could have a positive effect on our mental health.
The protective role is ascribed to their nutritional properties, where nuts, legumes, fruits and vegetables (sources of omega-3 fatty acids, vitamins and minerals) could reduce the risk of depression.”

Relatively small dietary changes were enough to reduce depression risk, Dr Sanchez-Villegas explained:

“A threshold effect may exist.
The noticeable difference occurs when participants start to follow a healthier diet.
Even a moderate adherence to these healthy dietary patterns was associated with an important reduction in the risk of developing depression.
However, we saw no extra benefit when participants showed high or very high adherence to the diets.
So, once the threshold is achieved, the reduced risk plateaus even if participants were stricter with their diets and eating more healthily.
This dose-response pattern is compatible with the hypothesis that suboptimal intake of some nutrients (mainly located in low adherence levels) may represent a risk factor for future depression.”

The research was published in the journal BMC Medicine (Sánchez-Villegas et al., 2015).
