Persistent Depression Damages Cognitive Functions, Study Concludes

Persistent Depression Damages Cognitive Functions, Study Concludes

A global study involving 9,000 people has found that persistent and recurring depression can lead to a shrinking of one key area of the brain. This zone is known as the hippocampus (Greek for seahorse) and it does indeed look like one.

This is the area which helps us store long term memories and plays an essential role in connecting our emotions to memories, personality, and consciousness. It can also help us with spatial navigation. It is one of the first areas of the brain to be affected by Alzheimer’s and explains why recent memories are such a big problem for those affected.

Research details

The depression research project involved 15 institutes from all over the world. Researchers compared people possessing normal hippocampi with those who were suffering from persistent depression. This was the largest comparative study of brain volumes ever carried out. The results showed that people who had no treatment for depression (or had recurring episodes over long periods) ended up with a smaller hippocampus.

Researchers used brain magnetic resonance imaging (MRI) and this clearly showed that two thirds of the depressed patients who had recurrences over long periods of time were the ones who had a smaller hippocampus.

“The more episodes of depression a person had, the greater the reduction in hippocampus size.” – Prof. Ian Hickie, co-director of the research project

What are the implications for the treatment of depression?

First, the good news is that treatment with anti-depressants may help to preserve the size of the hippocampus. There are a wide variety of these drugs available, including Selective Serotonin Reuptake Inhibitors, or SSRIs, which help to balance serotonin and can improve mood. Other popular medications include tricyclic antidepressants.

Of course, it must be remembered that all anti-depressants are required by the FDA to carry a black box warning of possible suicidal thoughts. This usually occurs at the beginning of treatment in teens and young adults or if a drug or dosage is changed.

“There is a lot of nonsense said about antidepressants that constantly perpetuates the evils of them, but there is a good bit of evidence that they have a protective effect.”- Prof. Ian Hickie.

Experts are now convinced that medication in treating depression is just one of the many alternatives available.

Why talk therapy is a valid alternative

Talk therapy is another possible treatment for depression, with various types that can suit individual needs. The chance to talk about depression without being judged, misunderstood or even criticized cannot be overestimated. It is a great way to approach problems and possible ways of solving them. Most medications can never do that quite as effectively.

Additionally, there is a wide range of supplements and lifestyle changes which can help a patient to maintain balance and prevent relapses. These can range from exercise which helps the brain to rewire itself in positive ways to dietary and mindfulness routines.

Research presents no conclusive results regardging the use of supplements but it seems that fish oil, SAMe and folic acid hold out some promise.

“There’s promising evidence for certain supplements for depression. But more research needs to be done before we’ll know for sure.” – Dr. Ian Cook, Director of the Depression Research Program at UCLA.

The way forward

Depression is still not fully understood. We know that certain areas of the brain such as the hippocampus are involved, but experts are not sure how they all interlink and what mechanisms are at work.

“Despite intensive research aimed at identifying brain structures linked to depression in recent decades, our understanding of what causes depression is still rudimentary.”- Prof. Jim Lagapoulos, co-author of the research project, Brain and Mind Research Institute, University of Sydney.

One thing is certain. We have learned from the research on the hippocampus that lack of treatment or recurring depression are affecting the brain. Processing emotions and memories are at risk. That sends a very clear message — there may be other areas of the brain affected which may have more serious consequences. But this damage is in many cases also reversible.

This is why we can never ignore depression and always seek treatment when or if it should happen to us or our loved ones.

8 Simple Mindfulness Exercises to Bring Peace and Happiness to Your Life

8 Simple Mindfulness Exercises to Bring Peace and Happiness to Your Life

In life, we all need to be conscientious of what we are doing. You don’t need to live a life of stress if you don’t want to. You can achieve peace and happiness in life by carefully building mindfulness exercises into your life’s routine.

Exercising mindfulness isn’t rocket science and as importantly, you can do it. It will, however, take a few tries to get into the groove of things but once you get it, it is like riding a bike, you will never lose it.

Trust me. It’s in your best interest to learn and put these mindfulness exercises into practice. In this article, I will share with you 8 mindfulness exercises that will help you to boost your energy, vitality and live a more peaceful and happier life.

Why Is It Hard to Live A Peaceful And Happy Life?

Our Habitat Has Become Too Technological

The world has accepted the idea that technology is often the cure for all evil. We have accepted, as a society, that everything technological will make us live a better life without fully investigating the many side effects that modernity brings.

There are a number of technological side effects that have a tremendous impact on your life that the media rarely tells you about.[1] Some of them include self-harm, economic inequality, having less sex, and even suicide. The global community is becoming less happy because of technology.

How can anybody live a peaceful and happy life when they are depressed? Technology advancements, ladies and gents, is a major reason for why we are living a poor life because it has infiltrated our lives too much.

According to my research, Americans spend an average of 8 hours a day looking at the computer screen — The average screen time spent on smartphones alone is about 20 hours per week. That’s a lot! No wonder why living a happy and peaceful life is so difficult these days.

Too Many People Don’t Want to Unplug

Americans check their phones an average of 80 times during vacation.[2] Some admit to checking their smartphones 300 times every single day. In countries like Brazil, India and China, the situation is no different.

The reality is that people are constantly plugged into technological devices and this behavior is literally making people all over the globe fight an inner war with themselves, which consequently makes them very sad. As we know, war is the enemy of peace which won’t make anybody happy.

Listen carefully:

We have a global anxiety epidemic because people don’t want to unplug from their smartphones and most people aren’t doing anything to fix it. It is a sad state of affairs but very real. This obsession with technology is turning us into perishable robots who live terrible lives.

The era of anxiety is here to stay. There is little doubt about it. We can, however, fight back with the best remedy of all — We call it mindfulness!

Thank God there is an antidote to this whole technological madness. Without further ado, let’s go straight to the mindful exercises.

8 Mindfulness Exercises to Start Practicing

There are tons of mindfulness exercises available for you to engage with out there.[3] In the paragraphs below, I will include the best ones I’ve personally tried or have seen my close friends and family members try.

Are you ready for it? Let’s go!

1. Pray Daily

You should pray on a daily basis. Why is that you may ask — Well, because science has told us to do so.

When people pray, they feel peaceful, almost eliminating anxiety. Worries become secondary, and often gives people energy and hope to cope with the difficulties of life.

Prayer can make you more confident and focused. Prayer also helps you with self-control, helps to control pain, and can protect you against illnesses and disorders like cancer and high blood pressure. At least, this is what researchers from Harvard Medical School have said.[4]

Pray. You won’t regret it.[5]

2. Pay Attention to Your Inner Thoughts

A lot of people allow themselves to be influenced by their negative thoughts. Be different and resist believing in them. It is a bad habit that can lead to unhappiness.

By the way, if you do feel this way, chances are high that somebody other than you put these thoughts into your head.

Here is my secret to combat this cancer — look at things objectively. I bet that if you look at things as they are, you will realize that most if not all of your negative thoughts are only inside of your head.

If you pay close attention, you will quickly realize that these voices aren’t worth your time. Believe me — Ignoring them and looking at things with objectivity is often the best course of action.

3. Smile Often

Smiling will slow down your heart. It will also relax your body because when you smile, your body releases endorphins which in itself has a number of positive benefits for you as a person.

Smile often! You may want to smile early in the morning, during the day, and late in the evening. It is amazing what happens to you when you decide to smile instead of being grumpy.

Surrender your problems to a nice smile. You will notice two things. First, most people just don’t which makes them live a miserable life. Second, if you decide to smile often, you will eventually smile unconsciously which is the ideal.

The moment that you smile unconsciously, you then know that you are truly happy.

4. Organize Your Working Desk

A messy desk will make you less productive and can agitate and overstimulate you. You don’t want that.

When you clear your desk, you engage in deep inner-thinking and your systematic decision making ends up becoming therapeutic.

Most people realize that they are most creative when their creative space is clean and organized. The former often makes people more aware of what they are doing which lends to less stress and more productivity.

Organizing your desk will also make you more energetic and focused because order often decreases chaos which is a condition that often slows down daily progress.

5. Celebrate Your Friend’s Victories

I love this mindful exercise. One of the best ways to live a happy and peaceful life is to celebrate the victories of others. When you do that, you automatically make your friends in a better mood which makes you in a better mood, as well.

Happiness is contagious! We might as well celebrate others as much as we can. If you find out that your peer has won an award, celebrate with him! If your friend is the recipient of a local charity award, celebrate with her!

What is also awesome is that when you celebrate with others, they often celebrate with you in return. This, ladies and gentleman, will make you feel fantastic. You can’t go wrong with this one, period.

6. Listen to Your Spouse/Partner

God put someone in your life for a reason. You might as well listen to him or her.

I listen to my wife everyday. In fact, I often ask the following question to her, “Amanda, what are your thoughts about…” or “What am I missing about…” It is shocking what I hear back from her. Without her having much context and perspective, by the art of observation in my own nonverbal behavior and the behavior of others, she accurately gives me incredible insights which helps me out with living my life to the fullest.

I’m a firm believer that spouses are supposed to engage in interpersonal communication every day. I most definitely do and will continue doing it. You should do the same.

7. Give Yourself a Break from Technology

You can’t be in total equilibrium if your computerized devices control your life. You must get away from technology on a daily basis.[6]

How do you do that? This is my formula:

First, take this smartphone control test. It is only ten questions but this test will place you somewhere in the human robot cycle continuum.

If your score is between 25-30, take a break from the computer (or smartphone, pad, laptop/desktop) every twenty minutes and stop being on a computerized device after 8:00pm.

If you score between 30-35, still take a break every 20 minutes but stop being on these devices at 5:00pm.

If you score more than 35, you need to take action immediately.

Limit computer use as much as possible throughout the day. Give yourself as many breaks from the computer as possible. Are you ready for the challenge?

8. Go Exercise

Go exercise at least three times a week. I don’t care if you need to workout early in the morning, late in the evening, on the weekends or during work days. Working out is absolutely imperative for you to live happy and peaceful life.

The stresses of the modern world are too much for you to neglect this important mindfulness exercise. When you go to the gym, you burn calories, focus on activities one step at a time, your mind relaxes, anxiety decreases, you sweat and often think about topics unrelated to your work place among many other benefits.

You must exercise at least three hours each week for optimum results. Why? Just take a look at all the benefits of regular exercising:

The Bottom Line

It’s in your best interest to learn and put these mindfulness exercises into practice. Now that our habitat has become too technological and many people just don’t want to unplug, engaging in daily prayer, celebrate your friends’ victories, and listening to your spouse are among the best ways to be mindful about what you are doing and how you are living.

It is possible to live a happy and peaceful life. It only depends on you.

Go exercise! Take a break from technology and invest in you! Life is too short for distractions.
