Study Floats 'Provocative' New Theory on Alzheimer’s



A new study out of Harvard puts forward what the New York Times calls a “startling hypothesis” about Alzheimer’s. The research published in Science Translational Medicine suggests that old infections in the brain—or, more specifically, the body’s attempt to fight them off—may be at the root of the disease.

The study revolves around the telltale plaque in the brain associated with Alzheimer’s, which is caused by a buildup of a protein called amyloid beta. Scientists have never been sure why the protein begins to build up as people age.

“Does it play a role in the brain, or is it just garbage that accumulates?“ is how Harvard’s Rudolph Tanzi frames the question per New Scientist. His study suggests that it does indeed play a role, and an important one: The body produces the protein to fight off infections that pass into the brain through the blood-brain barrier; the problem occurs when it doesn’t get properly cleared away after the fight.

“It’s interesting and provocative,” an Alzheimer’s researcher at the University of California, San Francisco, tells the Times of theory. It’s been tested on mice and roundworms but not humans yet. "Most shocking of all,” writes Scientific American, “was that when they injected bacteria into the brains of Alzheimer’s mouse models, amyloid plaques—the hallmark of the disease—formed within 48 hours.”

If further research backs up the notion, it could lead to new ways of treating the disease. For example, if this protein that eventually causes trouble comes into being originally as a way to fight pathogens, “you could vaccinate against those pathogens, and potentially prevent this problem arising later in life,” says Tanzi’s co-author, Robert Moir of Massachusetts General Hospital. (Maybe memories lost to Alzheimer’s aren’t gone forever?)

Skin Picking Disorder: What It Is and How to Stop It



So, you pick your skin. We’ve all done it — picked at an unsightly scab or tugged at an annoying hangnail, only to regret it later. But if you find yourself picking at your skin frequently and find it difficult to resist the urge to pick at it, even when it’s painful and leaves your skin damaged, cut or swollen, you may have Skin Picking Disorder (SPD) or Excoriation Disorder.

What is Skin Picking Disorder?

According to Eliza Burroughs, a registered psychotherapist at CBT (Cognitive Behavioral Therapy) Associates in Toronto, SPD is pathological skin picking characterized by the recurrent picking of the skin that results in damage to the skin and leads to lesions. It affects between one to five per cent of the general population.

Those diagnosed with SPD will have made repeated unsuccessful attempts to stop or decrease the picking as well as experience significant distress or impairment in functioning as a result of the picking, and typically spend more than one hour per day picking, thinking about picking, and resisting urges to pick.

“Commonly picked sites include face, arms and hands, although it can be anywhere on the body,” Burroughs says. This can include healthy skin, minor irregularities, lesions, or scabs. Picking can occur with just fingers or tools such as tweezers or pins, and can get so bad that the person might be embarrassed to show their skin in public.

Among those diagnosed with SPD, the gender balance is dramatically skewed towards females. Approximately 75 per cent of people with SPD are women, according to Burroughs.

“It is unclear as to why this may be, however it may reflect treatment seeking behaviors based on gender or cultural attitudes as opposed to underlying biological differences between the genders,” she says. “For instance, it is possible that men feel more embarrassment or shame in seeking treatment for a mental health condition or an appearance-related concern.”

Why do people pick at their skin?

Like most mental health conditions, the causes of SPD are not entirely clear and probably multi-factorial. Genetics, mental functioning, emotional regulation and environmental factors all come into play.

”[SPD] may be related to certain emotional states. For example, stress, boredom, anxiety, fatigue, anger,“ she says. “Similarly, picking can occur when people are under or over stimulated.”

Burroughs says for some individuals the picking may be what she terms “automatic,” essentially done without full awareness. Alternatively, the reverse — “focused” picking — may occur.

“There may be a particular skin irregularity that is targeted and the person may experience a sense of tension if they try to resist or delay the picking and then experience relief once they can fulfill the urge,” she says.

What do you do if you have SPD?

First, it’s important to understand that there are options. There are many physicians, psychiatrists, psychologists, and dermatologists who specialize in SPD treatment, like Burroughs herself. She provides Cognitive Behavioural Therapy (CBT) to her patients dealing with the disorder.

“This includes habit reversal training, and psychoeducation and strategies that target the thoughts and behaviours associated with SPD,” she says.

There are currently no medications approved specifically for use in the treatment of SPD, however, some SPD pharmacological studies have looked at the same kind of medications used for OCD or other body-focused repetitive behaviors like Trichotillomania (compulsive hair pulling), says Burroughs. However, she recommends talking to a physician or psychiatrist before making any decisions.

If therapy or medication is, in fact, not the right course of action for you, Burroughs has provided some helpful ways to lessen the urge to pick:

1.) Target the sensation another way. For example, if your skin is itchy, use a brush to rub lightly against the skin

2.) Make it difficult for the fingers to automatically start picking. For example, tape fingers or wear gloves in high risk situations (e.g. while watching T.V.)

3.) Do a competing response (a behavior that makes it virtually impossible to do the picking behavior). For example, clench fists, take-up knitting, doodle.

4.) Mindfulness and meditation can help overcome urges by increasing awareness of the urge, physical sensations, and related thoughts.

5.) Relaxation training, deep breathing, progressive muscle relaxation

6.) Regular exercise

7.) Maintaining a balanced lifestyle with healthy sleep habits and diet

8.) Ask a friend or loved one to help but make sure you set the rules. For example, they are allowed to gently tap you if they notice you picking but they’re not allowed to grab your hand. Everyone is comfortable with different styles. One person may want a gentle approach; another may prefer having their hand pulled away.

How Yoga Made Me Respect The Hell Out Of My Body



I can remember my 10-year-old self looking into a full-length mirror and thinking I was "bigger than the other girls." I wasn't. Yet an unhealthy relationship with my body persisted from that day on.

Years of volleyball, starting in grade school, made my thighs bulky and muscular. I stuck to dresses and never wore jeans or shorts for fear of looking heavy in my lower half. Black became my default wardrobe when I read in a teen magazine that the color was slimming. Every time I looked in the mirror, I found something that wasn't good enough, something that I would change.

I wasn't alone in this either. I heard it in the lamenting "Ugh, I look so fat" from the girl next to me at the sink in the high school bathroom. I'd watch my friends untag themselves from photos because they didn't like how they looked. Dissatisfaction was the norm and still is today for many women.

The expectations placed on us and how we're supposed to look are nearly impossible to achieve. It's no wonder that I struggled for years to make peace with my body! Now when I think about the anxiety and hours I wasted obsessing, all I wish is that I could have that time back.

Yoga changed everything for me.

I'd always been flexible so I tried out a yoga class because I figured I'd be good at it. I was immediately hooked. The quiet space, cool people, and natural high I felt after a class kept me coming back for more.

Even in the yoga studio—the one place that's supposed to be free of judgment—I often caught myself playing the comparison game. I would try in vain not to stare at the beautiful people in their standing splits. Jealousy would rear its ugly head, and I'd wonder why I didn't have so-and-so's body or why I couldn't yet make a headstand look effortless.

Until one day in class the voices in my head quieted long enough for me to catch a glimpse of my own power.

I looked in the mirror and saw the strong, muscular legs that I had hated for so long. The epiphany hit me that those legs allowed me to hold poses that the twig limbs I once longed for couldn't handle. I saw my shoulders and arms that were tight and toned from countless chaturangas. My skin glowed with health and newfound calmness as a huge grin broke across my face.

I left that yoga class walking on air. A shift was starting to take place in the way I looked at myself. Rather than criticizing my body based on what it looked like, I began appreciating everything I was capable of doing. I no longer cared as much about looking a certain way. Instead, I started to work toward accomplishing feats of strength and flexibility. Working toward advanced poses (and achieving them!) has made me grateful for a body that can move and bend and hold itself upside down.

It's still a challenge at times to stay positive and not fall back into old habits of criticism. Maintaining a regular practice helps, as does pausing to take a deep breath and mentally list three things I'm grateful that my body can do.

Nowadays, when I notice myself looking in the mirror and thinking about what I'd change, I redirect my thoughts to be thankful for my health. Yoga gave me the perfect body by helping me to appreciate the one I already had. I don't have washboard abs, and I'm OK with that. But this beautiful, capable body is the place my soul calls home, and I'm making every effort to respect that.

A Refreshing Smoothie Packed With Protein To Fuel Your Summer

3 Fitness Myths That Are Holding You Back



Everyone, at one time or another, has been given less-than-great advice for their health. Fitness and weight loss, due to their touchy and unique nature, have been particularly clouded with mountains of bad advice over the years. And if you are like everyone else, sifting through it can be hard, and tedious. As a personal trainer, I see my clients believing in some of the same big myths, over and over again. Here's some of the loudest, and most erroneous, advice that could be slowing down your fitness gains, and what you should do instead.

1. If I take a workout supplement, I don't have to work as hard.

This fitness myth is mostly perpetuated by the radical claims that supplements, both natural and unnatural, make. Countless supplements claim they can “speed up your metabolism” or “burn fat for you” or even “put muscle on you.” This is just not true. Working out will help you speed up your fat burning, not a supplement. And eating right, and eating enough, will help you put on muscle. Besides, even if a supplement could help, there could be a trade-off. In the end, the chemicals that fill those bottles could do more harm than good to your fitness gains by damaging your glands and leading to poor health.

2. I have to go to the gym because I need weight machines to get fit.

So many people think that they need to go to the gym so that they can use all of the special machinery that is available. But lifting free weights is just as effective as, if not better than, using weight-lifting machinery. Machines do not mimic the body’s natural movement, but rather, can restrict your movement and even be harmful if they are used incorrectly.

One of the biggest advantages of using free weights in place of heavy machinery is that you have the freedom to work out from your own home. Investing in your own set of weights at home can eliminate the need for expensive gym memberships. This gives you the luxury of working out on your own time, in your own home.

3. Running on the treadmill is the most effective form of cardio.

Every day I see people sweating away on the treadmill, logging long miles at one easy pace—sometimes for hours! It’s no secret that cardio is pushed on us as the best weight-loss option at the gym. It’s also great for your heart and your health. But not all cardio is the same; there are two types to consider. One is steady-state cardio, the type you will get just running on the treadmill, at the same speed from start to finish, for an hour a day. This type of cardio burns fat for the length of time you do it. But, the second type of cardio, HIIT (high-intensity interval training), actually burns fat for up to 24 hours after your workout.

HIIT workouts tend to be shorter but more intense than traditional cardio, and they can burn more calories through out the day. Sure, you can do them on the treadmill—but you can't just press one button and zone out to your favorite TV show. And the beauty of HIIT is that you can do it anywhere, incorporating pretty much any type of cardio: running, cycling, swimming, circuit training, you name it.

It’s true that there is a lot of good fitness advice out there. But sifting through the mounds of bad advice and myths that are perpetuated over and over again can take a lot of work. These top three now-busted myths should help you realize what may be holding you back—and how to break through to the next level, no matter what your fitness goals.

A Food-Based Approach To Protecting Kids' Teeth (It's Not Just About Sugar!)



The epidemic of tooth decay in our children has increased over the past 30 years. In fact, a study by the American Academy of Pediatric Dentistry shows that tooth decay is now the most common chronic childhood disease in the U.S.

As a dentist, my approach focuses on diet first—even more than brushing and flossing. Investigation into how cavities form reveals that simple dietary habits can lead to almost 100 percent cavity prevention.

Parents have long thought that if they brushed their child's teeth long enough, flossed them regularly, and kept soda and candy to a minimum that their children wouldn't get cavities.

But it's possible to get cavities without ever touching candy or soda. Beyond any genetic predisposition to tooth decay, cavity-causing snack foods with high concentrations of simple carbohydrates are the true culprits. Snack foods we commonly give to young children, such as dry cereal, crackers, and dried fruit, convert to lactic acid, which wears away tooth enamel and causes cavities.

But parents with youngsters know it isn't practical to completely restrict carbs from their child's diet. And the good news is they don't have to. This is because it's not the amount consumed but the frequency with which simple carbs make contact with the teeth. For example, drinking a smoothie in one sitting is better than taking drinks from a sippy cup over several hours. A zero-cavity program doesn't require a complete family diet overhaul if you know how to work the system.

To achieve zero cavities for your child—as well as older children and adults—here are the five prevention principles I recommend:

1. Protect baby teeth.

Don't fall for the myth that baby teeth don't matter because children will lose them at a young age. While baby teeth may begin falling out at age 5 or 6, children keep their back molars until ages 10 to 12. Cavities in baby teeth need to be treated. Preventing cavities through diet, even at a young age, removes the trauma for everyone involved.

2. Offer teeth-friendly foods.

Fat, protein, and fiber do not cause cavities. Simple or processed carbohydrates do. This means, counterintuitively, you are better off feeding your child a piece of 70 percent dark chocolate than a pretzel, cracker, or handful of raisins.

Starches, including not only sugar but all dried, processed flours, cling to the teeth and cause a large percentage of cavities. For this reason, eating bread and fresh fruit is better than eating crackers and dried fruit. You don't have to eliminate all carbs from the diet—you just have to change the quality of the carbs and how they're consumed.

3. Promote organized eating instead of grazing.

If you floss your child's teeth twice a day but let him drink chocolate milk all day long, your child will still get cavities. How your child eats is as important as what your child eats.

Think of it like this: carb-rich foods + time on teeth = cavities.

This means that allowing your child to graze on snacks or sip juice or milk throughout the day is a recipe for a mouth full of cavities. Teeth stay coated in cavity-producing acid for too many hours. Establish six "mini meals" a day and feed your child only at these organized meal- and snack times, with water in between.

4. Make water your ally.

The adage "The solution to pollution is dilution" holds true in the mouth. Drinking water with, or immediately after, meals and snacks is a simple way to reduce cavity worry. Offer water instead of juice or milk when your child is thirsty between meals.

5. Teach good brushing and flossing.

Bacteria in the mouth breaks down simple carbs into cavity-causing lactic acid. Removing bacteria and reducing simple carbs is key to cavity prevention. Until children reach the age of 5 or 6, they need help from a parent to brush their teeth properly.

Parents should give their child a "perfect" brushing before bed, with nothing to eat or drink except water afterward. With young children, a great brushing may only take 20 or 30 seconds, as long as the parent is doing the brushing. After age 6 or 7, have them transition to brush on their own for two minutes, twice a day. You only need to floss the teeth that are touching.

The bottom line: Instilling good habits for 100 percent cavity prevention means establishing organized snack times, giving your child teeth-friendly foods, and maintaining daily brushing and flossing routines.

How To Tap Into Your Intrinsic Happiness



With two kids outgoing, social kids we meet a lot of parents. And a lot of prospective parents seem to be drawn into our orbit as well. The other day I was talking with a woman who was obviously, uncomfortably pregnant. But she was excited, you could tell, her brain stuffed full of baby books and eyes glimmering with anticipation.

“I can’t wait to see how the whole Nature vs. Nurture thing plays out,” she said.

(pause)

My wife spoke first. “No, no. There is no versus. Children have a nature and you can nurture it.” The woman raised her eyebrow. This wasn’t the answer she’d expected. “It’s only when you make it a versus thing that you have real problems,” I added, probably needlessly, because I always have to say something.

Those of us with kids know. There’s a person there, a unique personality, at 4 or 5 months. I’d say that person is there even earlier but we lack the tools to detect it, and babies can’t do much more than burble, eat, and poop to express themselves.

As Dr. Seuss says, “No one is youer than you.” And this essential you, the you who you have always been, lies below the level at which we typically define ourselves. Below what you do for money, who you love, whether you’re a boy a girl, gay/straight/bi, the you that lies below your thoughts and feelings about life.

And certainly below the level of our problems. In fact, it’s fair to say that many of the most-vexing problems we struggle with arise because we become disconnected with our essential selves. We don’t, truly, know our nature. And if we don’t know that, how can we nurture it? Perhaps our parents never really understood us (perhaps because they didn’t really understand themselves) and pushed is into molds that don’t fit. It’s not their fault. They were doing the best they could.

The good news is that as meditators, we have a wonderful tool with which to reconnect to our core selves, to ground ourselves in whom we really, truly are and always have been. The Veda teaches that this essential you is happy, whole and complete. It wants nothing. It needs nothing added to it. It is the source of all the happiness and love you’ve ever felt. Happiness is your nature. Meditation is how we nurture it.
