Transcendental Meditation has dramatic benefits for those with PTSD

A pilot study involving 41 military veterans and 5 active-duty soldiers diagnosed with clinical levels of PTSD has found that one month of transcendental meditation produced dramatic benefits, with 37 (80%) having their symptoms reduced to below the clinical level, and 40 having a clinically significant decrease of more than 10 points.

A test 90 days later also showed that PTSD symptoms continued to improve, and a further three individuals had dropped to below the clinical level.

Brain changes seen in veterans with PTSD after mindfulness training

A pilot study involving 23 military veterans with PTSD found that those who received mindfulness training showed reduced PTSD symptoms, and brain changes that suggest a greater ability to shift and control attention. Mindfulness training was given to 14 veterans, while the other 9 received ‘control’ group support. Both groups were given brain scans before and after the treatment program.

Exercise and meditation help beat depression

A small study involving 22 students with depression and 30 mentally healthy students had positive results from a program that combines mental training through meditation and physical training through aerobic exercise. After eight weeks, those with depression showed a nearly 40% reduction in depressive symptoms, and said they did not spend as much time worrying about negative situations taking place in their lives as they did before the study began. There were also changes in brain activity that may reflect better cognitive control.

Interestingly, those in the control group also reported fewer depressive symptoms.

The program involved two sessions a week, with each one having 30 minutes of focused attention meditation followed by 30 minutes of aerobic exercise. They were told that if their thoughts drifted to the past or the future they should refocus on their breathing - enabling those with depression to accept moment-to-moment changes in attention.

Inflammation and depression fuel each other

A review of 200 studies on depression and inflammation has concluded that depression and inflammation fuel one another, with inflammation playing a key role in the development of depression in some people, and depression priming greater physiological responses to stress.

Moreover, depression that is caused by chronic inflammation is resistant to traditional therapy methods. However, it is more responsive to activities such as yoga, meditation, omega-3 fatty acids, NSAIDS and exercise.

The review indicates that treatment for depression needs to consider its pathway. The researcher suggests that chronic inflammation is most common in individuals who have experienced stress in their lives, including lower socio-economic status or those who experienced abuse or neglect as children. Other contributing factors are a high-fat diet and high body mass index.

If inflammation is a significant factor, it needs to be treated in tandem with the depression.

Better sleep and tai chi reduce inflammation

Stress, including sleep disturbance, is a major contributor to inflammation in the body. Insomnia is associated with increased risk for depression, medical comorbidities, and mortality.

A study involving 123 older adults (55+) with insomnia randomly assigned them to one of 3 types of classes: cognitive behavioral therapy for insomnia, tai chi, or a sleep seminar (the control condition).

Cognitive behavioral therapy for insomnia reduced insomnia symptoms and levels of the inflammation marker C-reactive protein, and reversed activation of molecular inflammatory signaling pathways. These benefits were maintained for 16 months.

Tai chi also reduced inflammation, reducing the expression of inflammation at the cellular level and reversing activation of inflammatory signaling pathways. It marginally reduced levels of C-reactive protein. Again, these benefits were maintained for 16 months.

Those participants assigned to the sleep seminar classes showed no significant changes in inflammatory markers, as expected.

Mindfulness meditation appears to help improve sleep quality

A small clinical trial involving 49 older adults (average age 66) found that the group who were given a standardized mindfulness meditation program had greater improvement in sleep score than the group given a sleep hygiene education program. They also showed greater improvement on secondary measures of insomnia symptoms, depression symptoms, fatigue interference and fatigue severity. However, differences between the groups were not seen for anxiety, stress or inflammatory signaling, the last of which declined in both groups.

Mindfulness may increase susceptibility to false memories

Mindfulness meditation is associated with various positive benefits, one of which is improved attention, but it might not be all good. A new study suggests that it may have negative cognitive consequences.

The study included three experiments, in the first two of which undergraduates carried out a 15-minute guided exercise: one group was instructed to focus attention on their breathing without judgment (mindfulness group); the other group was told to think about whatever came to mind (mind-wandering group; the control).

Why older adults lose working memory capacity

I've reported before on the idea that the drop in working memory capacity commonly seen in old age is related to the equally typical increase in distractability. Studies of brain activity have also indicated that lower WMC is correlated with greater storage of distractor information. So those with higher WMC, it's thought, are better at filtering out distraction and focusing only on the pertinent information. Older adults may show a reduced WMC, therefore, because their ability to ignore distraction and irrelevancies has declined.

Why does that happen?

Evidence for the benefits of meditation in fighting age-related cognitive decline

Submitted by Fiona McPherson on

A review of meditation research reported in January last year concluded that there were insufficient good studies to allow us to say that meditation clearly improves attention and cognition. Studies from 2014 suggest three factors that might be part of the reason for inconsistent research findings:

Meditating leads to better grades

Submitted by Fiona McPherson on

Three classroom experiments have found that students who meditated before a psychology lecture scored better on a quiz that followed than students who did not meditate. Mood, relaxation, and class interest were not affected by the meditation training.

The noteworthy thing is that the meditation was very very basic — six minutes of written meditation exercises.

The effect was stronger in classes where more freshmen students were enrolled, suggesting that the greatest benefit is to those students who have most difficulty in concentrating (who are more likely to drop out).
