Risk For Suicide is Higher Among Veterans When Compared With U.S. Civilian Adults

In 2014, an average of 20 Veterans died by suicide each day. Six of

the 20 were users of VHA services

In 2014, Veterans accounted for 18 percent of all deaths by suicide

among U.S. adults and constituted 8.5 percent of the U.S. adult

population

In 2014, rates of suicide were highest among younger Veterans

(ages 18–29) and lowest among older Veterans (ages 60+).

Suicide rate among recent Veterans is 50 % higher than non-

military civilians.

Current Treatments for PTSD

Pharmaceutical

Therapeutic: Exposure/Cognitive Behavioral

Problems

Overall: High dropout

Pharmaceutics: aversive side effects, results mixed

Therapy: difficulty revisiting trauma; substantial residual effects

Stigma

Unwillingness to be a victim/dependent & rely on drugs/therapist

Post-Traumatic Stress Disorder (PTSD) Diagnostic Criteria – DSM-5

Anxiety disorder that develops after exposure to trauma:

A. Exposure to actual or threatened death/injury

B. Intrusion Symptoms (thoughts, distressing dreams, dissociative reactions)

C. Avoidance Symptoms (memories, thoughts, feelings)

D. Negative cognitive and mood symptoms (amnesia for event, detachment

from others)

E. Arousal and reactivity (hyper-vigilance, Startle, Anxiety, Insomnia)

Meditation is effective for treating PTSD: Systematic Review and Meta-Analysis

10 trials (N=643)

Cohen’s d = 0.41; CI [0.81, 0.01]

PTSD symptoms for adjunctive meditation interventions were statistically

significantly different compared with all comparators in favor of meditation

Substantial heterogeneity in study quality

Sudarshan Kriya Yogic (SKY) Breathing

Prana – translates to “life force” or “energy”

Pranayama- “control of energy” and “expansion of energy”

Breathing techniques have potential to relieve stress-related illness including

-anxiety

-depression

-PTSD

Breathing under both voluntary and involuntary control via complex feedback

loops involving

- autonomic visceral networks

-brains stem nuclei

- limbic system

- cortical areas

- neuroendocrine system

By voluntarily controlling breathing it is possible to influence these networks

and hence mood and cognition.

Sudarshan Kriya Yogic (SKY) Breathing Developed by Sri Sri Ravi Shankar, cofounder of the

International Association for Human Values

International Association of Human Values holds special

consultative status with the United National Economic

and Social Council (ECOSOC).

Widely used across many cultures

Follows a reproducible sequence

Research and clinical experience demonstrates it

significantly alleviates

Stress

Anxiety

Depression

SKY has 4 breath components

1. Three-stage pranayam using ujjayi – 2-4 breaths per minute. Subjective

experience of mental and physical calmness with alertness

2. Bhastrika – (Bellows Breath) – air is rapidly inhaled and forcefully exhaled at 30

breaths per minute. It engenders excitation followed by calmness

3. Chanting of “om” chanted 3 times with very prolonged expiration.

4. Sudarshan Kriya (cyclical breathing) –an advanced form of cyclical breathing at

various rates.

SKY courses also include: Yoga-based stretching

Guided relaxation after the practice

Aspects of CBT and psychoeducation

Group exercises to teach self-awareness, connectedness and create a sense of

community

Follow-up Study Based on Mechanism of Action

Mechanisms of SKY meditation are currently

unclear

Mechanism is important to define in order to

refine treatment

From the perspective of cognitive neuroscience,

potential mechanisms may relate to changes in

sleep and memory processing

Post-Traumatic Stress Disorder (PTSD) Diagnostic Criteria – DSM-5

Anxiety disorder that develops after exposure to trauma:

A. Exposure to actual or threatened death/injury

B. Intrusion Symptoms (thoughts, distressing dreams, dissociative reactions)

C. Avoidance Symptoms (memories, thoughts, feelings)

D. Negative cognitive and mood symptoms (amnesia for event, detachment

from others)

E. Arousal and reactivity (hyper-vigilance, Startle, Anxiety, Insomnia)

Sleep problems represent two of the diagnostic criteria for PTSD in DSM-5

B2: recurrent distressing dreams in which

the content and/or affect of the dream are

related to the traumatic event.

E6: sleep disturbance (e.g., difficulty falling

or staying asleep or restless sleep).

The Paradox of Traumatic Memory

Emotionally salient memories are more

persistent and vivid than non-emotional

memories, but normally there is a gradual

reduction in emotional salience over time

Why don’t traumatic memories fade over time?

Memory Consolidation

Memory consolidation during sleep allows

memories to be integrated with existing

memories

Memory consolidation may involve

decoupling of emotion and memory during

REM sleep (Walker).

REM sleep may be chronically impaired,

or defragmened (Melman) in PTSD so

emotional “tag” is not removed from the

trauma memory

PTSD and Cognition

Relationship between PTSD and cognitive functioning is not clear

Typically effects memory, attention, and executive functioning.

Memory problems could be accounted for by attentional difficulties –

e.g., internal distraction due to hyperarousal, hypervigilance, re-

experiencing.

Some anatomical studies show reduced hippocampal volume. This

may be cause or effect.

Possible that standard neuropsychological tests are not sufficiently

sensitive to PTSD, which would be revealed by computerized

cognitive battery.

Summary

Tests of cognition function and sleep are not usually

included in meditation studies.

Tests of cognitive function and sleep provide objective

measures for studies of PTSD and complement self-

reported measures.

Mechanisms of meditation-based therapies are currently

unclear.

Mechanism important to refine and optimally implement

meditation-based approaches.

More research needed on alternative and complimentary

treatments
