The Art Of Mindfulness

The practice of mindfulness has been a hot topic recently, but what does mindfulness actually mean and how does one practice it? One Baylor College of Medicine expert discusses this.

“Mindfulness is the art of paying attention with a purpose and without judgement,” said Dr. Monica Alzate, licensed clinical social worker and assistant professor of family and community medicine. “Essentially, the idea is to be in the moment and become aware.”

Research has shown that mindfulness techniques work to help prevent, reduce and even eliminate physical and mental health symptoms, Alzate explained. These techniques also have been proven to be very helpful for people with anxiety and depression as well as those with anger management and concentration issues. Research is being done to study why mindfulness works.

“We still do not know exactly how or why mindfulness techniques work, but we know that they do,” she said.  

For example, one experiment showed that a group of people who practiced mindfulness based stress reduction for eight weeks had positive changes in the structure of the brain, such as increase in hippocampal thickness (involved in memory, learning, and modulation of emotional control), and decrease in brain cell volume in the amygdala (responsible for fear, anxiety, stress). Other studies have shown changes in gray matter volume and density, as well as in activation levels of the insula, which is involved in the process of awareness. These changes have been observed through neuroimaging studies using Electroencephalogram and Functional MRI.  

There are several types of mindfulness exercises that Alzate recommends practicing. They include:

Five senses exercise: For this exercise, you decide which of the senses you want to focus on for five minutes. For example, if you choose sight, then you would focus on picking out five objects you have never noticed before or if you choose hearing, you would then listen to five things you have never paid attention to before. You can do this exercise while simultaneously practicing abdominal breathing.

Body scan exercise: For this exercise you use your mind to scan your body all the way from the crown of your head to your toes. When doing this exercise you should try to exhale through your nose as it helps relax you more. This exercise can be as short as five minutes or as long as 30 minutes.

Mindful eating exercise: This technique involves focusing on the food you eat and can be helpful for people with eating issues. For this technique, you take a small piece of whatever you are going to eat in your hand and observe it without judgment. After observing it, you pick it up, put it close to your ear and move it around so you can hear the sound that might come from the food’s texture. Eventually, you put the piece of food in your mouth and you slowly feel the food as it breaks down and, lastly, you swallow it. The idea of this technique is to help people slow down and pay attention to what they are eating and to be present while doing so.   

brainthinkingAlzate emphasized the importance of practicing mindfulness techniques before you need to use them and suggested practicing with a mindfulness expert so you can learn how to properly execute different techniques.  

“You have to learn the exercises and practice them properly when you are not experiencing stress, that way when you need them you know how to do them,” she said. “Many people wait until the moment that they need to use a technique to start using it, but this will not work. Training helps the brain get used to how you are going to react when you practice a mindfulness technique. You cannot learn a new thing in a moment of stress.”

She added that although abdominal breathing is not a mindfulness technique in itself, it is the first step of many mindfulness practices, and many people do not do it correctly. To help practice abdominal breathing, Alzate said you should start by lying down and putting a very light pillow or a stuffed animal on your abdomen with a pillow behind your head so you can see if the pillow or stuffed animal goes up and down when you are breathing. If it does, then you are breathing correctly. Once you have mastered this, then you can put a hand on your chest and a hand on your abdomen so you can actually start feeling your body when you are breathing. After you are able to do this comfortably, you can start practicing your abdominal breathing while you are sitting, standing and walking. It is important to be able to do abdominal breathing in all situations because you may find yourself needing it when you are sitting in your car stuck in a traffic jam or standing in the back of a long line.  

Once you have mastered how to properly practice mindfulness techniques, Alzate suggests downloading a mindfulness app so you have access to mindfulness resources at any time.

She cautions that for some people with higher anxiety levels practicing mindfulness alone may not be enough and she recommends seeking help from a mental health professional.

“Practicing mindfulness can be a great first step for any kind of change that you may want to accomplish whether it is a short-term change like refocusing during a meeting or a long-term change like managing an anger problem,” Alzate said.

The Difference Between Home Genetic Testing And Carrier Screening

familywalk2Home DNA testing kits have become increasingly popular in recent years and there are now many different companies, like 23andMe, Ancestry, and National Geographic, that offer this service to consumers commercially. Without ever leaving their home, people can order a genetic testing kit, take a DNA sample, and send it back for testing. The results offer detailed data about ancestry, migration, and personal physical or character traits. Some of these companies are even offering health testing that includes carrier status information for some diseases. But how does this compare to other, more established forms of genetic carrier screening?

Genetic Carrier Screening

All methods of genetic carrier testing can give you an idea of how likely you are to pass a certain genetic trait or condition on to your offspring. There are hundreds of possible variants or genetic diseases that can be tested for in any individual. The likelihood of your child developing a genetic condition depends on a variety of factors, such as how it is inherited (what chromosome the genetic mutation is associated with) and what genetic variants your partner has. Carrier genetic testing can be performed with a saliva sample, a buccal swab, or a blood test.

Testing Criteria

Most commercially available at-home testing kits are only intended for autosomal recessive carrier screening. When a baby is conceived, they inherit a gene from each parent for every trait. An autosomal recessive disorder occurs when a person inherits two genes that cause the disorder, one from each parent. A person can also be a carrier, which means that they only inherited one of these genes, and therefore do not have the disorder but are at risk of passing it on to their offspring. If one partner tests positive as a carrier for a particular genetic disorder, the other partner will also need to be tested to determine if their child has a risk for being born with the autosomal recessive condition.

In reality, there are many different kinds of inherited disorders. Genetic diseases that are inherited in other ways (like X-linked inheritance, when there is a mutation on the X chromosome) usually can only be tested for with more thorough forms of carrier genetic testing, performed through a blood test at a healthcare provider’s office.

If you are interested in a comprehensive list of genetic conditions that you should consider getting screened for, your best bet is speaking to your doctor about the different carrier screening tests. The tests recommended by your doctor can often provide more information and information about additional genetic diseases not found in today’s at-home DNA testing kits. Before you decide what kind of genetic test is good for you, you should have a good idea of what genetic diseases or variants should be tested for and make sure your selected test meets these criteria.

Accuracy

At-home DNA tests are done precisely that way, in your own home and under your own supervision. It is obvious that their accuracy may be affected by many environmental factors such as human error during sample collection. A huge benefit of getting a blood test for carrier screening is that your sample is taken by a professional and is handled by laboratory-trained technicians throughout the process. These laboratories have many years of specialized experience dealing specifically with DNA carrier screening. This can lead to higher quality samples and therefore, higher quality results.

Consult Your Doctor

It can be fun to find out about your ancestry and where your family came from, but when you are also testing for risk or carrier status for certain health conditions, it is best to consult with an expert. If you have questions about which kind of genetic carrier screening to perform, you should consult your doctor for more information. When you receive your results, you will likely bring them to your health professional or genetic counselor for guidance on next steps, so it makes sense to consult them beforehand about which kind of testing they prefer.

Additional Testing

If you move forward with the at-home carrier screening kit, it’s important to note that depending on your results, additional testing may be recommended. Your doctor may order additional tests, like a carrier DNA screening or panel (performed via blood draw) to confirm your at-home results.
