Why You Should Never Read Online Illness or Medication Forums, and Why You Should be Skeptical of Google Search Results as Well

The first thing many people seem to do when they get a diagnosis of a physical or mental illness is to go to the internet and search on that illness. Patients who are prescribed medications do the same. Often the search results lead to internet forums. These forums consist of user-generated content that usually is not moderated or edited by any professional. Anyone can post on these forums. This seems reasonable, right? But in this article, I’m going to tell you why, for the most part, you should avoid reading these forums. And I will also tell you why you should be skeptical of Google search results regarding any illness.

When people read on forums about their illness or medication, they get scared. Many of the forum posts will say that your illness leads to awful and dire outcomes and that the medications prescribed to you will make you depressed, addicted, or crazy.

For instance, I often treat tinnitus patients. Samplings of the forums that cover tinnitus suggest that most of the people who post on these forums are completely miserable and suffering terribly from their tinnitus.

So what’s the problem here? Isn’t this useful information? Can’t patients learn something interesting and helpful from these forums?

Unfortunately, Internet illness forums often present a distorted, grim, and negative impression of most illnesses and most medications. Why is this? The main reason is because of selection and sampling bias. The groups of people who post on illness forums are not a representative sample of people with a particular illness. Let’s use tinnitus as an example. If you read the tinnitus forums you would assume that everybody with tinnitus is anxious and depressed about it.

But actually, we know from research studies that roughly 20% to 40% of the population experience tinnitus symptoms from time to time. We also know that roughly 2% of people who have tinnitus symptoms suffer psychologically. So the data from research suggests that a small subset (2%) of people who have tinnitus symptoms suffer anxiety and depression as a result of their tinnitus. Most people (98%) with tinnitus symptoms do not suffer significantly or they have adapted over time and gotten over their suffering.

But the forums are full of posts from the people who suffer the most. People who don’t suffer don’t spend their time posting. And people who have overcome their suffering also don’t post. So reading the forums gives a tinnitus patient a distorted and scary view of the experience of tinnitus.

The other problem in reading internet information about illnesses is the way that Google Search ranks and orders search results. When you search on tinnitus, what you might not realize is that Google presents pages in order of popularity, not in order based on how accurate or scientific they are. Sites that are clicked on more frequently will rise up in the Google search results and sites that are clicked on less frequently will fall down. When you do a Google search people typically click on the most shocking and scary links. “Tinnitus caused by alien abduction” will get a lot of clicks even though it may represent a site run by a single person who claims to have been abducted by aliens. Thus the alien abduction tinnitus site will move up in the Google rankings.

Boring scientific sites fall down in the search rankings. That’s because they have scientific names that don’t encourage people to click on the links.

So how can patients get accurate information about their illness or about medication treatments?

One way is to search within scientific and medical sites. For instance, Medscape is an excellent website that offers medical articles about almost every illness. WebMD is another site more designed for lay people, which also offers good information. If you want to search scientific articles you can use the PubMed search engine which searches published research articles.

Let’s do a Google search on tinnitus. Overall, the 1st page of Google results is pretty representative of medical and scientific sites. But the 3rd listing titled “In the news”, is an article “Martin McGuinness tells of misery living with tinnitus,” from the Belfast Telegraph. Pretty grim, you think, misery!

But if you actually clicked through to the article you would get a very different impression because what Martin McGuinness actually says is that tinnitus “had a limited impact on day-to-day life and work and that family, friends and work colleagues were very supportive. It does not limit me in a professional or personal capacity.” This is a much more positive view than suggested by the title and the Google link.

This is a great example of why the Internet is dangerous. The headline is what’s called clickbait, a link that falsely represents the actual page, which is designed to attract people’s clicks.

Forums about medication are also problematic. Many psychiatric medications can have side effects. For most people, these side effects are minimal or tolerable and are overbalanced by the benefits of the medications. For a minority of patients, the side effects are not minimal and these are the patients who are over-represented in most Internet medication forums. Also, on an Internet forum you never really know all of the medications the person is taking, the accurate dosages, as well as their underlying illness.

There is one more problem with reading about illnesses on the Internet. It’s one that particularly disturbs me. Many websites, even websites that purport to be objective, actually are selling something. They may be selling a supplement or vitamin, or an e-book or some other kind of program to treat an illness. Obviously, to increase sales, these commercial websites will paint a distorted negative picture of any illness or condition. They may also disparage other more traditional and scientifically validated treatments or drugs. In general, you should be skeptical of any information that comes from a website that sells products or services.

To review:

  1. Take Google search results with many grains of salt. Remember that Google orders search results by popularity not by accuracy.
  2. Beware of Internet illness and medication forums. By and large, they are populated with an unrepresentative sample of illness sufferers, the ones who suffer the most and cope the least well. Reading them will depress you and make you anxious.
  3. If you want to get information about your illness or potential treatments, consider using established and reputable medical and psychological information sites. An exhaustive list of best medical sites can be found at the Consumer and Patient Health Information Site. Some of the good medical sites include MedscapeWebMD, and MayoClinic. Some of the best sites for mental health information include PsychCentral, NIMH, American Psychiatry Association, American Psychology Association.
  1. Finally, remember that a very large percentage of websites are actually selling something, and be skeptical of information from these sites.

In conclusion, suffering any illness or condition is unpleasant and sometimes scary. Don’t make it worse by consuming information on the Internet in a random way. Be skeptical and selective and remember that Google is not always your friend. Often a good physician or good psychologist can give you clear and balanced information.

Good News! You May Be Getting More Sleep Than You Think, Especially If You Suffer Insomnia!

The Wall Street Journal today had a very interesting article about how people with insomnia tend to greatly underestimate how much sleep they get and overestimate how long it takes them to fall asleep. They also overestimate how often they wake up at night.

Roughly 30% of adults have some insomnia each year. About 10% of people have chronic insomnia which means that you have trouble sleeping three times a week or more. According to the Journal article, 42% of insomniacs who actually slept the normal amount (6 hours or more) underestimated how much they slept by more than an hour. I looked up the research article which was published in Psychosomatic Medicine. According to this research, insomniacs who slept six hours or more typically showed a profile of high depression and anxiety and low coping skills according to psychological testing.

What’s also interesting is that even though insomniacs may be sleeping six or more hours a night, there does appear to be some real differences in their brainwave activity compared to good sleepers. Even though they are asleep, their brains are more active, which may account for why they perceive their sleep to be less than it really is.

Another interesting factoid was that normal people tend to overestimate how much sleep they get. Most people when asked how much sleep they get will answer between seven and eight hours, but they are actually getting six hours. That’s why people tend to be so sleep deprived. For most people six hours is not enough sleep to feel really good.

So what’s the answer to this sleep estimating dilemma? It turns out there is a very simple answer. The two gold standards for measuring sleep are brainwave measurements and activity measurements. While brainwave measurements are difficult to come by in the home, activity measurements are very easy and inexpensive to obtain. Many of the current fitness tracker’s have a sleep tracking function. For instance, according to my Xiaomi Mi Band, which cost me the grand sum of $15, last night I was in bed for seven hours and 58 minutes, and got three hours 20 minutes of deep sleep and four hours and 38 minutes of light sleep. I was awake for one minute. (Yes, I know, please don’t hate me all you insomniacs!)

For insomniacs who worry about how much sleep they are getting, I recommend buying a fitness tracker and wearing it every night. The best ones automatically track sleep without having the requirement that you push a button to activate sleep mode. This is pretty important as most people forget to press the button. I have been pretty happy with my Xiaomi Mi Band, which you can buy directly from the company  but I’m sure there are other brands of fitness trackers which offer similar features.

Also, as I’ve written about previously here and here, cognitive behavioral therapy for insomnia (CBT-I) may also improve the quality of sleep as well as the quantity. Some studies show that CBT-I improves people’s ability to accurately estimate their sleep time, and it also may calm  the over-activity of the brain that occurs when insomniacs sleep.

So here’s the executive summary for all of you sleep-deprived folks:

1. If you are an insomniac who is anxious and depressed, then you are probably getting more sleep than you think. Buy a fitness tracker with a good sleep tracking function, and you will see how much sleep you are actually getting.

2. If you want to improve the quality of your sleep, either practice meditation or see a CBT psychologist for CBT-I, as both of these interventions seem to lower the activity of the brain during sleep, which will improve your perception of your own sleep.

3. If you consistently feel anxious or depressed, consider getting some cognitive behavioral therapy for these problems, as they may contribute to sleep difficulties.

I’m off to bed now and hope I don’t have insomnia now that I’ve written about it!

 

Cognitive Behavioral Therapy for Insomnia (CBT-I) Outperforms Drugs for Insomnia

The New York Times today had an excellent article The Evidence Points to a Better Way, which summarized what I have written about before. Cognitive behavioral therapy for chronic insomnia (CBT-I) kicks the butt of drug therapy!

One study compared CBT with a common sleeping pill called Restoril and found that the CBT treatment led to larger and longer lasting improvements in sleep. Another study found that CBT treatment outperformed the drug Ambien, and that CBT alone was even better than CBT plus Ambien combined.

Even more impressive are the results of a large meta-study which was published today. This meta-study, which combined data from 20 clinical trials and involved over 1000 patients with chronic insomnia showed that CBT I resulted in these patients falling asleep 19 minutes faster and having 26 minutes less wakefulness during each night on average. The actual study is protected by a pay wall, but the summary results are here.

One might question the clinical relevance of these outcomes. Does falling asleep 19 minutes faster really make that much of a difference? Does sleeping an extra 26 minutes a night make patients feel better the next day? As a good sleeper, I don’t really know the answer to these questions.

But I suspect that the biggest impact of CBT-I is in affecting the person’s perception of control over sleep. One of the horrible things about chronic insomnia is that patients feel out of control in terms of their sleep. They worry tremendously about the impact of loss of sleep on their ability to function the next day. It is this worry cycle that actually can create insomnia.

So I suspect that even though the effects were durable but modest, that the overall treatment made a large difference in how people felt. There is a big difference between taking 45 minutes to fall sleep and 20 minutes to fall sleep. And I suspect that sleeping an extra 26 minutes a night actually does make a difference. I know that I feel much better on eight hours of sleep as opposed to 7.5 hours of sleep.

When I work with patients on CBT-I one of the things I work on is helping the patient lower their anxiety about the impact of sleep restriction. As crazy as it sounds, one of the interventions I typically use is to have the patient stay up all night and go to work the next day. Although they are typically very tired, they discover that they can focus and function, maybe not at 100% but at an adequate level, maybe 75% or so. This lowers a lot of the anxiety about insomnia, since even a bad night of insomnia typically leads to quite a bit more sleep than staying up all night.

Other than the time and energy that a patient must invest in learning CBT-I skills, there are no side effects of cognitive behavioral therapy for insomnia. All sleeping medications have significant side effects the most troubling of which involve impaired cognition and coordination during the night and the following day. This impaired coordination and cognition leads to increased falling in the elderly, and probably also leads to an increase in automobile and other accidents. Because drug companies don’t want studies done on this issue, there are relatively few studies, but one study in Norway found that there was a doubling of traffic accidents among patients who took a variety of sleeping pills. Another study that compared 10,000 sleeping pill users to 23,000 nonusers found that the sleeping pill users were five times more likely to die young than nonusers.

So what does this mean to the person suffering insomnia? It means that you should avoid taking sleeping medications, and get cognitive behavioral therapy for insomnia. This kind of therapy typically does not take very many sessions. I teach the basic skills of CBT-I in about 4 to 6 sessions, and typically the entire course of CBT-I takes less than 10 sessions. There are also options for CBT- I online and even apps that run on your phone. One such app that runs on both android and iPhone is called CBT-I Coach. This app was developed with your tax dollars as part of a large Veterans Administration insomnia treatment program, and is excellent.

It’s getting late, so rather than have to experiment with any of these treatments, I’m off to bed…

Calming An Overactive Brain–My Day In Pacifica

Today I am taking a seminar with William Sieber calling Calming an Overactive Brain. He’s an excellent presenter, with a good sense of humor, a down to earth speaker. He’s got a nice balance of enough confidence to be a an excellent speaker without being arrogant. This is quite rare in the seminar business. Even though there’s a lot of stuff I already know I’ve learned a number of  interesting things. The seminar is on the ocean in Pacifica, and outside the windows of the meeting hall I can see the waves crashing on the sand.

One funny thing happened at lunch. I had hurried out to the next door cafe so I could get a table before the crowds hit. Dr. Sieber showed up, looking for a table. I invited him to join me at my table. We started talking and discovered some remarkable commonalities! Both of us had attended Yale for training, me for undergrad, and he for graduate school. He had worked closely with Judith Rodin and Peter Salovey while there. Judy Rodin had been my first psychology professor, and probably the one that influenced me to go into psychology. Peter I had known while teaching at the Bridge, Stanford’s peer counseling center, many years before, and in whose book I have a chapter on Listening Skills. Eventually he went on to teach at Yale, and now is Yale’s president. More surprisingly, Dr. Sieber and I both interned at the Palo Alto Veterans Hospital, in different years! We had a fun lunch reminiscing.

About the seminar. He spoke at length about sleep and it’s impacts on health and wellness. For instance, one study showed that those who got less than 6 hours of sleep were 42% more likely to get diabetes. Or that those with the most disturbed sleep were 97% more likely to die in the next 20 years. Poor sleep makes you more prone to pre-diabetes, anxiety, upsetting emotions, not to mention lowering overall mood and vitality.

Less sleep also affects appetite and eating. Leptin is the hormone that lowers our appetite, and ghrelin is the hormone that increases appetite. With sleep deprivation our leptin goes down, and our ghrelin goes up, and on average we consume 250 calories more on days after a bad night’s sleep. This doesn’t sound like much, but it adds up to about 25 pounds of extra weight per year if you chronically sleep poorly.

I also learned how to assess sleep. The key metric is “sleep efficiency”. This means what percent of the time you are in  bed trying to sleep are you actually asleep. A good number is 90-95%. This is hard.  It means if I am in bed for 8 hours a night, I am asleep 95% of the time, or all except 24 minutes. What is your sleep efficiency? He went over how to use the sleep efficiency log to diagnose sleep problems and guide treatment.

One other interesting factoid for all of you pet lovers. Fifty-three percent of pet owners have disturbed sleep due to their pets.  Maybe we should all shut the door at night and train our pets to sleep somewhere else other than in bed with us.

He discussed how to fix common sleep problems. One such pattern is mine, the delayed sleep cycle. This is the night-owl pattern, going to bed late and getting up late. To fix it, he suggested a short term use of sleep aids to shift the cycle to earlier bedtimes, combined with bright light in the mornings, and no screen light for an hour before bedtime. Cutting back on caffeine use is also helpful.

Others suffer the early phase shift, those who fall asleep too early, and get up too early. To shift these people he recommended getting bright light exposure in the early evening so the melatonin production is suppressed until later in the evening.

In the afternoon we got into discussion of moods and control. Discussing anxiety, he explained the key role that perceived control over situations plays in creating or ameliorating anxiety. Exercise turns out to be a strong treatment for anxiety. Most people with anxiety disorders do not exercise more than once a week, and those who exercise 3 or more times a week rarely have anxiety disorders.

Then he turned to relaxation training for anxiety. He made a great point—that even if you train people to relax deeply, the probability of them continuing to practice even four weeks later is very low. So instead, he shared a 20 second relaxation. Take two deep and slow belly breaths, exhaling for longer than you inhale. While doing that go somewhere relaxing in your mind, and experience that place (ie the beach) in the sensory modality of your preference—seeing, hearing, smelling, or feeling. Make up a two word description of that sensory experience, i.e. “Warm sun”. Repeat that phrase as you take your 2 deep breaths, during the exhale.

He suggested pairing this relaxation practice with something you do multiple times a day. So for instance, pair it with hitting the Send button on your email. That way you will remember to practice a quick relaxation many times a day.

He also shared James Pennebaker’s work, which I often use with patients. Pennebaker found that writing about traumatic events for just 30 minutes a day for 4 days in a row had a fairly profound impact on future emotional and physical health. Interestingly, the initial impact was negative, more anxiety and upset, and more susceptibility to illness. But after three to six months, the pattern reversed, with people showing less upset and anxiety, and better health.

Finally, he shared some info about new findings about heart rate variability (HRV). HRV is the change in the rate of your heartbeat over each beat and each several seconds. It turns out that having MORE HRV is better for both mental and physical health. People with anxiety disorders have less HRV. And it turns out the the three factors that most predict low HRV are: sedentary lifestyle, a cynical and hostile view of life, and anxiety.

Can you retrain your heart rate variability? Yes, with both breathing retraining, and with biofeedback. And it turns out that when you learn to increase your HRV, your anxiety goes down. Very interesting and cool stuff.

The final part of the workshop was about mindfulness. I won’t even try to summarize this part of the seminar, as it was very detailed, and even profound. Perhaps I’ll blog about it later.

Overall, it was a good learning experience, with a wonderful view of the ocean the whole time!

Now I need to go to sleep early….

SSRI Antidepressants Given in High Doses May More than Double the Risk of Suicide in Adolescents and Young Adults Under 25

So you’ve got a teenage child who’s depressed. What do you do? A new study published in the Journal JAMA Internal Medicine suggests what NOT to do. In this study, conducted at Harvard, the authors looked at 162,625 people from ages of 10 to 64 years old who took selective serotonin reuptake inhibitors (SSRIs) for depression. (These are drugs like Paxil, Prozac, Celexa, Zoloft, Lexapro, and Luvox, and their generic equivalents.)

The researchers looked at the relationship between initial starting dose and the rate of deliberate self harm and suicidal behavior. What they found was shocking. They found that for people under the age of 25 starting SSRI medication at a higher than normal dose more than doubled the risk of self harm behavior! This translated into one additional occurrence of self harm behavior for every 136 patients who were treated with high-dose SSRIs. This is a lot of additional suicide attempts!

Interestingly enough, for adults 25 to 64 years old, there was only a very small increase in self harm behavior with high-dose SSRI treatment, and the overall risk of self harm behavior was much lower.

Delving more deeply into the data is interesting. In the under 25-year-old range, 142 patients attempted suicide within one year. The rate was 14.7 suicide events per 1000 person-years for those who started SSRIs at average doses, and 31.5 suicide events per 1000 person-years in those who started at high doses. For the older adults the rates were 2.8 per 1000 person-years for average doses, and 3.2 suicide events per 1000 person-years for those who started at high doses.  These numbers translated into seven more suicide events per 1000 for patients under 25 during the first 90 days of treatment with high dose SSRIs.

Also, disturbingly, the study found that 18% of all patients were started on high initial doses of antidepressants, despite clinical guidelines that specifically recommend starting at a low dose and titrating the dose upwards slowly.  The typical doses of common antidepressants are 20 mg for Prozac, 20 mg for Paxil, 20 mg for Celexa, 50 mg for Zoloft, and 10 mg for Lexapro. For unknown reasons, almost one in five patients were started at higher doses than these.

Why were almost one in five patients started at higher doses than these? I suspect I know the answer, although it wasn’t discussed in the study. Unfortunately, the vast majority of patients are given antidepressants by their internist or family physician or pediatrician. In contrast to psychiatrists, these practitioners do not have the time or bandwidth see patients every week. So they are more likely to start the patient at a higher dose.

Most psychiatrists will start patients at subclinical doses and gradually increase the dosage to avoid side effects. It certainly has been my clinical experience that some general medicine doctors do not do a very good job of administering antidepressants. That is why with most of my patients, especially if they can afford it or have good insurance coverage, I suggest that they seek the advice of a psychopharmacologist or psychiatrist for psychoactive drugs.

The authors of this paper point out that recent research suggests that antidepressant medication is at best only slightly effective in young people and that the dosage of antidepressants are typically unrelated to their effectiveness. Given these two research findings, it certainly does not make any sense to start antidepressant treatment at a higher than average dose.

But I would go one step further. I would argue more strongly that in most cases it does not make sense to use antidepressant medications in young people at all. Why expose a young person to the heightened risk of suicide for what is at best a relatively modest improvement in mood?

This is even more relevant when you consider that there is an alternative treatment that has no side effects and has been shown to be effective. That is cognitive behavioral therapy (CBT) for depression. And there is even a specific cognitive behavioral therapy for suicide prevention that has been developed. (CBT-SP). This is a 12 week focused CBT program that in one study demonstrated that it significantly lowered the probability of a suicide event in suicidal adolescents.

If medication is going to be used, one recommendation that follows from all of this research is that it is good idea for doctors to follow the guideline of “start low and slow” when prescribing antidepressant medications to people under 25. Start at lower than typical doses, and very slowly and gradually increase the doses. While this is happening the patient should be followed on a weekly basis.

If the prescribing doctor is not a psychiatrist who sees the young person weekly, it’s a good idea to pair this with weekly psychotherapy sessions. The weekly psychotherapy session, especially when conducted by someone skilled in cognitive behavioral therapy who evaluates mood and suicidal ideation at every session, can be an essential safety measure when prescribing antidepressants to young people. Or consider treating with CBT alone,  which may very well be just as effective.

Because this is so important, I am listing some references below.

No jokes today, as suicide is not a laughing matter…
