  • ("They carried all they could bear, and then some, including a silent awe for the terrible power of the things they carried." - Tim O'Brien, "The Things They Carried" )

    (「彼らは背負えるものすべてを背負い、そしてさらに、背負ったものの恐ろしい力に対する無言の畏怖を含めて、背負った」。- ティム・オブライエン「The Things They Carried」)

  • Many of us will experience some kind of trauma during our lifetime.


  • Sometimes, we escape with no long-term effects.


  • But for millions of us, those experiences linger, causing symptoms like flashbacks, nightmares, and negative thoughts that interfere with everyday life.


  • This phenomenon called post-traumatic stress disorder, or PTSD, isn't a personal failing.


  • Rather, it's a treatable malfunction of certain biological mechanisms that allow us to cope with dangerous experiences.


  • To understand PTSD, we first need to understand how the brain processes a wide range of ordeals,

    PTSD を理解するためには、まず、さまざまな試練を脳がどのように処理しているかを理解する必要があります。

  • including the death of a loved one, domestic violence, injury or illness, abuse, rape, war, car accidents, and natural disasters.


  • These events can bring on feelings of danger and helplessness, which activate the brain's alarm system, known as the "fight-flight-freeze" response.


  • When this alarm sounds, the hypothalamic, pituitary, and adrenal systemsknown as the HPA axiswork together to send signals to the autonomic nervous system.


  • That's the network that communicates with adrenal glands and internal organs to help regulate functions like heart rate, digestion, and respiration.


  • These signals start a chemical cascade that floods the body with several different stress hormones, causing physiological changes that prepare the body to defend itself.


  • Our heart rate speeds up, breathing quickens, and muscles tense.


  • Even after a crisis is over, escalated levels of stress hormones may last for days, contributing to jittery feelings, nightmares, and other symptoms.


  • For most people, these experiences disappear within a few days to two weeks as their hormone levels stabilize.


  • But a small percentage of those who experience trauma have persistent problems, sometimes vanishing temporarily only to resurface months later.


  • We don't completely understand what's happening in the brain.


  • But one theory is that the stress hormone cortisol may be continuously activating the "fight-flight-freeze" response while reducing overall brain functioning, leading to a number of negative symptoms.


  • These symptoms often fall into four categories:


  • Intrusive thoughts like dreams and flashbacks.


  • Avoiding reminders of the trauma.


  • Negative thoughts and feelings like fear, anger, and guilt.


  • And reactive symptoms like irritability and difficulty sleeping.


  • Not everyone has all these symptoms or experiences them to the same extent and intensity.


  • When problems last more than a month, PTSD is often diagnosed.


  • Genetics, ongoing overwhelming stress, and many risk factors, like pre-existing mental illnesses or lack of emotional support, likely play a role in determining who will experience PTSD.


  • But the underlying cause is still a medical mystery.


  • A major challenge of coping with PTSD is sensitivity to triggersphysical and emotional stimuli that the brain associates with the original trauma.

    PTSD に対処するための大きな課題は、脳がトラウマと関連付けるトリガー⏤物理的・感情的刺激に過敏になることです。

  • These can be everyday sensations that aren't inherently dangerous but prompt powerful physical and emotional reactions.


  • For example, the smell of a campfire could evoke the memory of being trapped in a burning house.


  • For someone with PTSD, that memory activates the same neurochemical cascade as the original event.

    PTSD の人にとって、その記憶は元の出来事と同じ神経化学的連鎖を活性化させるのです。

  • That then stirs up the same feelings of panic and helplessness as if they're experiencing the trauma all over again.


  • Trying to avoid these triggers which are sometimes unpredictable can lead to isolation.


  • That can leave people feeling invalidated, ignored, or misunderstood, like a pause button has been pushed on their lives while the rest of the world continues around them.


  • But there are options.


  • If you think you might be suffering from PTSD, the first step is an evaluation with a mental health professional who can direct you towards the many resources available.

    PTSD の可能性がある場合、まず、精神衛生の専門家による診断を受け、利用可能な多くの対策を紹介してもらうことが必要です。

  • Psychotherapy can be very effective for PTSD, helping patients better understand their triggers.

    PTSD には心理療法が非常に有効で、患者さんが自分のきっかけについてよりよく理解できるようになります。

  • And certain medications can make symptoms more manageable, as can self-care practices like mindfulness and regular exercise.


  • What if you notice signs of PTSD in a friend or family member?


  • Social support, acceptance, and empathy are key to helping in recovery.


  • Let them know you believe their account of what they're experiencing and that you don't blame them for their reactions.


  • If they're open to it, encourage them to seek evaluation and treatment.


  • PTSD has been called "the hidden wound" because it comes without outward physical signs.

    PTSD は、外見的な症状がないため、「隠れた傷」とも呼ばれています。

  • But even if it's an invisible disorder, it doesn't have to be a silent one.


  • Mental health conditions impact millions of people around the world, yet are often misunderstood.
