New study shows that use of psychedelic drugs does not increase risk of mental illness

An analysis of data provided by 135,000 randomly selected participants – including 19,000 people who had used drugs such as LSD and magic mushrooms – finds that use of psychedelics does not increase risk of developing mental health problems. The results are published in the Journal of Psychopharmacology.

Previously, the researchers behind the study – from the Norwegian University of Science and Technology in Trondheim – had conducted a population study investigating associations between mental health and psychedelic use. However, that study, which looked at data from 2001-04, was unable to find a link between use of these drugs and mental health problems.

“Over 30 million US adults have tried psychedelics and there just is not much evidence of health problems,” says author and clinical psychologist Pål-Ørjan Johansen.

“Drug experts consistently rank LSD and psilocybin mushrooms as much less harmful to the individual user and to society compared to alcohol and other controlled substances,” concurs co-author and neuroscientist Teri Krebs.

For their study, they analyzed a data set from the US National Health Survey (2008-2011) consisting of 135,095 randomly selected adults from the US, including 19,299 users of psychedelic drugs.

Krebs and Johansen report that they found no evidence for a link between use of psychedelic drugs and psychological distress, depression, anxiety or suicidal thoughts, plans and attempts.

In fact, on a number of factors, the study found a correlation between use of psychedelic drugs and decreased risk for mental health problems.

“Many people report deeply meaningful experiences and lasting beneficial effects from using psychedelics,” says Krebs.

However, Johansen acknowledges that – given the design of the study – the researchers cannot “exclude the possibility that use of psychedelics might have a negative effect on mental health for some individuals or groups, perhaps counterbalanced at a population level by a positive effect on mental health in others.”

Despite this, Johansen believes that the findings of the study are robust enough to draw the conclusion that prohibition of psychedelic drugs cannot be justified as a public health measure.

Krebs says:

“Concerns have been raised that the ban on use of psychedelics is a violation of the human rights to belief and spiritual practice, full development of the personality, and free-time and play.”

Commenting on the research in a piece for the journal Nature, Charles Grob, a paediatric psychiatrist at the University of California-Los Angeles, says the study “assures us that there were not widespread ‘acid casualties’ in the 1960s.” However, he urges caution when interpreting the results, as individual cases of adverse effects can and do occur as a consequence of psychedelic use.

For instance, Grob describes hallucinogen persisting perception disorder, sometimes referred to as “a never-ending trip.” Patients with this disorder experience “incessant distortions” in their vision, such as shimmering lights and colored dots. “I’ve seen a number of people with these symptoms following a psychedelic experience, and it can be a very serious condition,” says Grob.

Acceptance and Commitment Therapy (ACT) shows that self-compassion may be more important than self-esteem

On By A.P.In mental health, mental illness, psychologist, psychology, Science, The Brain1 Comment

Few concepts in popular psychology have gotten more attention over the last few decades than self-esteem and its importance in life success and long-term mental health. Of course, much of this discussion has focused on young people, and how families, parents, teachers, coaches, and mentors can provide the proper psychological environment to help them grow into functional, mature, mentally stable adults.

Research shows that low self-esteem correlates with poorer mental health outcomes across the board, increased likelihood of suicide attempts, and difficulty developing supportive social relationships. Research also shows that trying to raise low self-esteem artificially comes with its own set of problems, including tendencies toward narcissism, antisocial behavior, and avoiding challenging activities that may threaten one’s self-concept.

This division in the research has led to a division amongst psychologists about how important self-esteem is, whether or not it’s useful to help people improve their self-esteem, and what the best practices are for accomplishing that.

In one camp, you have people who believe improving self-esteem is of paramount importance. On the other side of the fence are those who feel the whole concept of self-esteem is overrated and that it’s more critical to develop realistic perceptions about oneself.

But what if we’ve been asking the wrong questions all along? What if the self-esteem discussion is like the proverbial finger pointing at the moon?

New research is suggesting this may indeed be the case, and that a new concept — self-compassion — could be vastly more important than self-esteem when it comes to long-term mental health and success.

Why the Self-Esteem Model Is Flawed

The root problem with the self-esteem model comes down to some fundamental realities about language and cognition that Acceptance and Commitment Therapy (ACT, pronounced all as one word) was designed to address.

The way psychologists classically treat issues with self-esteem is by having clients track their internal dialog — especially their negative self talk — and then employ a number of tactics to counter those negative statements with more positive (or at least more realistic) ones. Others attempt to stop the thoughts, distract themselves from them, or to self sooth.

Put bluntly, these techniques don’t work very well. The ACT research community has shown this over and over again. There are many reasons that techniques like distraction and thought stopping tend not to work — too many to go into all of them here. For a full discussion, see the books Acceptance and Commitment Therapy or Get Out of Your Mind and Into Your Life. For the purposes of our discussion here, we will look at one aspect of this: How fighting a thought increases its believability.

Imagine a young person has the thought, “There is something wrong with me.” The classic rhetoric of self-esteem forces this person to take the thought seriously. After all he or she has likely been taught that having good self-esteem is important and essential for success in life. If they fight against the thought by countering it, however, that means the thought is confirmed. The thought is itself something that is wrong with the individual and has to change. Every time they struggle against it, the noose just gets tighter as the thought is reconfirmed. The more they fight the thought, the more power they give it.

This is a classic example of why in ACT we say, “If you are not willing to have it, you do.”

The simple fact is, we can’t always prevent young people from experiencing insecurity and low self-esteem. Heck, we can’t eliminate those feelings in ourselves. All people feel inadequate or imperfect at times. And in an ever-evolving, ever-more complex world, there is simply no way we can protect our young people from events that threaten their self-esteem — events like social rejection, family problems, personal failures, and others.

What we can do is help young people to respond to those difficult situations and to self-doubt with self-compassion. And a couple of interesting studies that were recently published show that this may indeed offer a more useful way forward not only for young people, but for all of us.

What Is Self-Compassion?

Before we look at the studies, let’s take a moment to define self-compassion.

Dr. Kirstin Neff, one of the premier researchers in this area, defines self-compassion as consisting of three key components during times of personal suffering and failure:
1. Treating oneself kindly.
2. Recognizing one’s struggles as part of the shared human experience.
3. Holding one’s painful thoughts and feelings in mindful awareness.

Given this context, the negativity or positivity of your thoughts isn’t what’s important. It’s how you respond to those thoughts that matters. Going back to the example above — “There is something wrong with me” — instead of fighting against that thought or trying to distract yourself from it, you could notice this thought without getting attached to it (become mindful), understand that it is common to all humans and part of our shared experience as people, and then treat yourself kindly instead of beating yourself up.

Does this approach really work better than simply improving self-esteem?

It seems it does.

A just-published longitudinal study that followed 2,448 ninth graders for a year found that low self-esteem had little effect on mental health in those who had the highest levels of self-compassion. That means that even if they had negative thoughts, those thoughts had minimal impact on their sense of well-being over time as compared to peers who didn’t have self-compassion skills.6

This suggests that teaching kids who suffer from self-esteem issues to be more self-compassionate may have more benefit than simply trying to improve their self-esteem.

The question is: How do we do that?

As it turns out, this is exactly where ACT excels.

Using ACT to Enhance Self-Compassion

Knowing that enhancing self-compassion has been shown not only to mitigate problems with self-esteem, but also impacts other conditions including traumatic stress. Jamie Yadavaia decided to see in his doctoral project if we could enhance self-compassion using ACT.

The results were promising.

A group of 78 students 18 years or older was randomized into one of two groups. The first group was put in a “waitlist condition” which basically means they received no treatment. The other group was provided with six hours of ACT training.

As anticipated, ACT intervention led to substantial increases in self-compassion over the waitlist control post-treatment and two months after the intervention. In this group self-compassion increased 106 percent — an effect size comparable to far longer treatments previously published. Not only that, but the ACT treatment reduced general psychological distress, depression, anxiety, and stress.

At the heart of all these changes was psychological flexibility, this skill seemed to be the key mediating factor across the board, which makes sense. After all, learning how to become less attached to your thoughts, hold them in mindful awareness, and respond to them with a broader repertoire of skills — like self-kindness, for example — has not only been posited in the self-compassion literature as a core feature of mental health but proven time and again in the ACT research as essential for it.

Taken together these studies have an important lesson to teach all of us.

It’s time for us to put down the idea that we have to think well of ourselves at all times to be mature, successful, functional, mentally healthy individuals. Indeed, this toxic idea can foster a kind of narcissistic ego-based self-story that is bound to blow up on us. Instead of increasing self-esteem content what we need to do is increase self-compassion as the context of all we do. That deflates ego-based self-stories, as we humbly accept our place as one amongst our fellow human beings, mindfully acknowledging that we all have self-doubt, we all suffer, we all fail from time to time, but none of that means we can’t live a life of meaning, purpose, and compassion for ourselves and others.

7 Very Bizarre (and Very Rare) Psychotic Hallucinations

The many documented cases of strange delusions and neurological syndromes can offer a window into how bizarre the brain can be.

It may seem that hallucinations are random images that appear to some individuals, or that delusions are thoughts that arise without purpose. However, in some cases, a specific brain pathway may create a particular image or delusion, and different people may experience the same hallucination.

In recent decades, with advances in brain science, researchers have started to unravel the causes of some of these conditions, while others have remained a mystery.

Here is a look at seven odd hallucinations, which show that anything is possible when the brain takes a break from reality.

1. Alice-in-Wonderland syndrome
This neurological syndrome is characterized by bizarre, distorted perceptions of time and space, similar to what Alice experienced in Lewis Carroll’s “Alice’s Adventures in Wonderland.”

Patients with Alice-in-Wonderland syndrome describe seeing objects or parts of their bodies as smaller or bigger than their actual sizes, or in an altered shape. These individuals may also perceive time differently.

The rare syndrome seems to be caused by some viral infections, epilepsy, migraine headaches and brain tumors. Studies have also suggested that abnormal activity in parts of the visual cortex that handle information about the shape and size of objects might cause the hallucinations.

It’s also been suggested that Carroll himself experienced the condition during migraine headaches and used them as inspiration for writing the tale of Alice’s strange dream.

English psychiatrist John Todd first described the condition in an article published in the Canadian Medical Association Journal in 1955, and that’s why the condition is also called Todd’s syndrome. However, an earlier reference to the condition appears in a 1952 article by American neurologist Caro Lippman. The doctor describes a patient who reported feeling short and wide as she walked, and referenced “Alice’s Adventures in Wonderland” to explain her body image illusions.

2. Walking Corpse Syndrome
This delusion, also called Cotard’s Syndrome, is a rare mental illness in which patients believe they are dead, are dying or have lost their internal organs.

French neurologist Jules Cotard first described the condition in 1880, finding it in a woman who had depression and also symptoms of psychosis. The patient believed she didn’t have a brain or intestines, and didn’t need to eat. She died of starvation.

Other cases of Cotard’s syndrome have been reported in people with a range of psychiatric and neurological problems, including schizophrenia, traumatic brain injury and multiple sclerosis.

In a recent case report of Cotard’s syndrome, researchers described a previously healthy 73-year-old woman who went to the emergency room insisting that she was “going to die and going to hell.” Eventually, doctors found the patient had bleeding in her brain due to a stroke. After she received treatment in the hospital, her delusion resolved within a week, according to the report published in January 2014 in the journal of Neuropsychiatry.

3. Charles Bonnet syndrome
People who have lost their sight may develop Charles Bonnet syndrome, which involves having vivid, complex visual hallucinations of things that aren’t really there.

People with this syndrome usually hallucinate people’s faces, cartoons, colored patterns and objects. It is thought the condition occurs because the brain’s visual system is no longer receiving visual information from the eye or part of the retina, and begins making up its own images.

Charles Bonnet syndrome occurs in between 10 and 40% of older adults who have significant vision loss, according to studies.

4. Clinical lycanthropy
In this extremely rare psychiatric condition, patients believe they are turning into wolves or other animals. They may perceive their own bodies differently, and insist they are growing the fur, sharp teeth and claws of a wolf.

Cases have also been reported of people with delusional beliefs about turning into dogs, pigs, frogs and snakes.

The condition usually occurs in combination with another disorder, such as schizophrenia, bipolar disorder or severe depression, according to a review study published in the March issue of the journal History of Psychiatry in 2014.

5. Capgras delusion
Patients with Capgras delusion believe that an imposter has replaced a person they feel close to, such as a friend or spouse. The delusion has been reported in patients with schizophrenia, Alzheimer’s disease, advanced Parkinson’s disease, dementia and brain lesions.

One brain imaging study suggested the condition may involve reduced neural activity in the brain system that processes information about faces and emotional responses.

6. Othello syndrome
Named after Shakespeare’s character, Othello syndrome involves a paranoid belief that the sufferer’s partner is cheating. People with this condition experience strong obsessive thoughts and may show aggression and violence.

In one recent case report, doctors described a 46-year-old married man in the African country Burkina Faso who had a stroke, which left him unable to communicate and paralyzed in half of his body. The patient gradually recovered from his paralysis and speaking problems, but developed a persistent delusional jealousy and aggression toward his wife, accusing her of cheating with an unidentified man.

7. Ekbom’s syndrome
Patients with Ekbom’s syndrome, also known as delusional parasitosis or delusional infestations, strongly believe they are infested with parasites that are crawling under their skin. Patients report sensations of itching and being bitten, and sometimes, in an effort to get rid of the pathogens, they may hurt themselves, which can result in wounds and actual infections.

It’s unknown what causes these delusions, but studies have linked the condition with structural changes in the brain, and some patients have improved when treated with antipsychotic medications.

Psychedelic mushrooms put your brain in a “waking dream,” study finds

Psychedelic mushrooms can do more than make you see the world in kaleidoscope. Research suggests they may have permanent, positive effects on the human brain.

In fact, a mind-altering compound found in some 200 species of mushroom is already being explored as a potential treatment for depression and anxiety. People who consume these mushrooms, after “trips” that can be a bit scary and unpleasant, report feeling more optimistic, less self-centered, and even happier for months after the fact.

But why do these trips change the way people see the world? According to a study published today in Human Brain Mapping, the mushroom compounds could be unlocking brain states usually only experienced when we dream, changes in activity that could help unlock permanent shifts in perspective.

The study examined brain activity in those who’d received injections of psilocybin, which gives “shrooms” their psychedelic punch. Despite a long history of mushroom use in spiritual practice, scientists have only recently begun to examine the brain activity of those using the compound, and this is the first study to attempt to relate the behavioral effects to biological changes.

After injections, the 15 participants were found to have increased brain function in areas associated with emotion and memory. The effect was strikingly similar to a brain in dream sleep, according to Dr. Robin Carhart-Harris, a post-doctoral researcher in neuropsychopharmacology at Imperial College London and co-author of the study.

“You’re seeing these areas getting louder, and more active,” he said. “It’s like someone’s turned up the volume there, in these regions that are considered part of an emotional system in the brain. When you look at a brain during dream sleep, you see the same hyperactive emotion centers.”

In fact, administration of the drug just before or during sleep seemed to promote higher activity levels during Rapid Eye Movement sleep, when dreams occur. An intriguing finding, Carhart-Harris says, given that people tend to describe their experience on psychedelic drugs as being like “a waking dream.” It seems that the brain may literally be slipping into unconscious patterns while the user is awake.

Conversely, the subjects of the study had decreased activity in other parts of the brain—areas associated with high level cognition. “These are the most recent parts of our brain, in an evolutionary sense,” Carhart-Harris said. “And we see them getting quieter and less organized.”

This dampening of one area and amplification of another could explain the “mind-broadening” sensation of psychedelic drugs, he said. Unlike most recreational drugs, psychotropic mushrooms and LSD don’t provide a pleasant, hedonistic reward when they’re consumed. Instead, users take them very occasionally, chasing the strange neurological effects instead of any sort of high.

“Except for some naïve users who go looking for a good time…which, by the way, is not how it plays out,” Carhart-Harris said, “you see people taking them to experience some kind of mental exploration, and to try to understand themselves.”

Our firm sense of self—the habits and experiences that we find integral to our personality—is quieted by these trips. Carhart-Harris believes that the drugs may unlock emotion while “basically killing the ego,” allowing users to be less narrow-minded and let go of negative outlooks.

It’s still not clear why such effects can have more profound long-term effects on the brain than our nightly dreams. But Carhart-Harris hopes to see more of these compounds in modern medicine. “The way we treat psychological illnesses now is to dampen things,” he said. “We dampen anxiety, dampen ones emotional range in the hope of curing depression, taking the sting out of what one feels.”

But some patients seem to benefit from having their emotions “unlocked” instead. “It would really suit the style of psychotherapy where we engage in a patient’s history and hang-ups,” Carhart-Harris said. “Instead of putting a bandage over the exposed wound, we’d be essentially loosening their minds—promoting a permanent change in outlook.”

Deep brain stimulation treatment for patients with obsessive-compulsive disorder (OCD)

On By A.P.In Anxiety, brain computer interface, CIAF, Da Brayn, deep-brain-stimulation, Medicine, Neuropsychiatric Disease, Obsessive Compulsive Disease, OCD, Technology, The Future, The SingularityLeave a comment

It seems simple: Walk to the refrigerator and grab a drink.

But Brett Larsen, 37, opens the door gingerly — peeks in — closes it, opens it, closes it and opens it again. This goes on for several minutes.

When he finally gets out a bottle of soda, he places his thumb and index finger on the cap, just so. Twists it open. Twists it closed. Twists it open.

“Just think about any movement that you have during the course of a day — closing a door or flushing the toilet — over and over and over,” said Michele Larsen, Brett’s mother.

“I cannot tell you the number of things we’ve had to replace for being broken because they’ve been used so many times.”

At 12, Larsen was diagnosed with obsessive-compulsive disorder, or OCD. It causes anxiety, which grips him so tightly that his only relief is repetition. It manifests in the smallest of tasks: taking a shower, putting on his shoes, walking through a doorway.

There are days when Larsen cannot leave the house.

“I can only imagine how difficult that is to live with that every single living waking moment of your life,” said Dr. Gerald Maguire, Larsen’s psychiatrist.

In a last-ditch effort to relieve his symptoms, Larsen decided to undergo deep brain stimulation. Electrodes were implanted in his brain, nestled near the striatum, an area thought to be responsible for deep, primitive emotions such as anxiety and fear.

Brett’s OCD trigger

Brett says his obsessions and compulsions began when he was 10, after his father died.

“I started worrying a lot about my family and loved ones dying or something bad happening to them,” he said. “I just got the thought in my head that if I switch the light off a certain amount of times, maybe I could control it somehow.

“Then I just kept doing it, and it got worse and worse.”

“Being OCD” has become a cultural catchphrase, but for people with the actual disorder, life can feel like a broken record. With OCD, the normal impulse to go back and check if you turned off the stove, or whether you left the lights on, becomes part of a crippling ritual.

The disease hijacked Larsen’s life (he cannot hold down a job and rarely sees friends); his personality (he can be stone-faced, with only glimpses of a slight smile); and his speech (a stuttering-like condition causes his speaking to be halting and labored.)

He spent the past two decades trying everything: multiple medication combinations, cognitive behavioral therapy, cross-country visits to specialists, even hospitalization.

Nothing could quell the anxiety churning inside him.

“This is not something that you consider first line for patients because this is invasive,” said Maguire, chair of psychiatry and neuroscience at the University of California Riverside medical school, and part of the team evaluating whether Larsen was a good candidate for deep brain stimulation. “It’s reserved for those patients when the standard therapies, the talk therapies, the medication therapies have failed.”

Deep brain stimulation is an experimental intervention, most commonly used among patients with nervous system disorders such as essential tremor, dystonia or Parkinson’s disease. In rare cases, it has been used for patients with intractable depression and OCD.

The electrodes alter the electrical field around regions of the brain thought to influence disease — in some cases amplifying it, in others dampening it — in hopes of relieving symptoms, said Dr. Frank Hsu, professor and chair of the department of neurosurgery at University of California, Irvine.

Hsu says stimulating the brain has worked with several OCD patients, but that the precise mechanism is not well understood.

The procedure is not innocuous: It involves a small risk of bleeding in the brain, stroke and infection. A battery pack embedded under the skin keeps the electrical current coursing to the brain, but each time the batteries run out, another surgical procedure is required.

‘I feel like laughing’

As doctors navigated Larsen’s brain tissue in the operating room — stimulating different areas to determine where to focus the electrical current — Larsen began to feel his fear fade.

At one point he began beaming, then giggling. It was an uncharacteristic light moment for someone usually gripped by anxiety.

In response to Larsen’s laughter, a staff member in the operating room asked him what he was feeling. Larsen said, “I don’t know why, but I feel happy. I feel like laughing.”

Doctors continued probing his brain for hours, figuring out what areas — and what level of stimulation — might work weeks later, when Larsen would have his device turned on for good.

In the weeks after surgery, the residual swelling in his brain kept those good feelings going. For the first time in years, Larsen and his mother had hope for normalcy.

“I know that Brett has a lot of normal in him, even though this disease eats him up at times,” said Michele Larsen. “There are moments when he’s free enough of anxiety that he can express that. But it’s only moments. It’s not days. It’s not hours. It’s not enough.”

Turning it on

In January, Larsen had his device activated. Almost immediately, he felt a swell of happiness reminiscent of what he had felt in the OR weeks earlier.

But that feeling would be fleeting — the process for getting him to an optimal level would take months. Every few weeks doctors increased the electrical current.

“Each time I go back it feels better,” Larsen said. “I’m more calm every time they turn it up.”

With time, some of his compulsive behaviors became less pronounced. In May, several weeks after his device was activated, he could put on his shoes with ease. He no longer spun them around in an incessant circle to allay his anxiety.

But other behaviors — such as turning on and shutting off the faucet — continued. Today, things are better, but not completely normal.

Normal, by society’s definition, is not the outcome Larsen should expect, experts say. Patients with an intractable disease who undergo deep brain stimulation should expect to have manageable OCD.

Lately, Larsen feels less trapped by his mind. He is able to make the once interminable trek outside his home within minutes, not hours. He has been to Disneyland with friends twice. He takes long rides along the beach to relax.

In his mind, the future looks bright.

“I feel like I’m getting better every day,” said Larsen, adding that things like going back to school or working now feel within his grasp. “I feel like I’m more able to achieve the things I want to do since I had the surgery.”
