Eye Movement Desensitization and Reprocessing (EMDR): Therapy for PTSD

By: Jessica Much

Post-traumatic stress disorder is a complex disorder affecting those who have experienced single or repeated trauma. The most commonly-known symptom of PTSD is flashbacks. Flashbacks occur when a person is reminded of the traumatic event by an environmental cue, known as a trigger, which leads to an episode of feeling as if they are experiencing the trauma all over again in real time. For instance, if someone who has been hit by a red car sees a red car while they are driving, it may remind them of the incident and cause them to have a vivid flashback of the event.

          For those who experience flashbacks, it may be hard to feel in control of their emotions, and they may feel helpless to stop them. However, there is a lesser-known therapy that can help ease the severity of flashbacks. Eye movement desensitization and reprocessing therapy (EMDR) was created by Francine Shapiro in the 1980s to address trauma through physical stimulation as well as talk therapy. EMDR believes that traumatic memories are stuck within an individual’s conscious (causing flashbacks), and must be reprocessed and unstuck by the patient to alleviate symptoms and their severity.

          During this therapy, patients are verbally guided through questions and feelings about their memories while bilateral brain activity in the patient is stimulated by the therapist through various methods (most commonly side-to-side eye movement). This encourages the reprocessing of memories from the emotional right brain hemisphere to the more logical left brain. Doing this can help reduce the emotional intensity of memories, as well as allow patients to change their beliefs about the memory (“My sexual assault is my fault” can be modified to “I am not to blame for what happened to me”). Additionally, reprocessing memories can help address symptoms of PTSD that are not directly attached to a memory, such as not sleeping well, being generally fearful, or lashing out at others.

          EMDR therapy shows significant results in the treatment of PTSD, especially when combined with other forms of therapy, such as cognitive behavioral therapy. Studies show that 84%-90% of single-trauma victims no longer met the criteria to be diagnosed with PTSD after three 90-minute sessions, and 77% of multiple trauma victims no longer meet the criteria after only six 50-minute sessions.

          EMDR is a quick, effective, and science-based treatment for PTSD. If you are suffering from recurring nightmares, flashbacks, have gone through single/repeated trauma, experience unidentified emotional outbursts, or want to reframe how you recall negative memories, this therapy might be right for you.

Mental Illness: Genetics or Environment?

Mental Illness: Genetics or Environment?

By: Isabelle Siegel

The term “Nature vs. Nurture” describes an age-old scientific debate regarding whether behavior, personality, and other individual characteristics are the result of nature—one’s biology and genetics—or nurture—one’s environment and upbringing. The development of mental illness is a prime example of the Nature vs. Nurture debate, as scientists and others seek to understand: Is mental illness caused by genetics or environment?

The Big Question. Is Nature or Nurture responsible for mental illness? This is essentially a trick question, as both Nature and Nurture contribute to the development of mental illness. In fact, it is ultimately the interaction between one’s genes and one’s experiences and environment that leads a person to develop a mental illness. According to the Diathesis-Stress Model, genetic predispositions develop into mental illnesses when they are met with stressful environments and/or experiences. For example, a person can be born with a genetic predisposition for depression, but that person may not develop depression unless they experience stressful environmental events such as abuse.

Nature. What are the biological and genetic causes of mental illness? It is well-documented that mental illness can be hereditary, or passed on within families. For example, a person is four to six times more likely to develop Bipolar Disorder if someone in their family has or had Bipolar Disorder. Another potent biological factor contributing to the development of mental illness is brain anatomy and brain chemistry. Research suggests, for instance, that people with schizophrenia have less active prefrontal cortices (the area of the brain associated with decision-making, planning, and personality). Other biological factors implicated in the development of mental illness include exposure to infection or toxins, damage during pregnancy, and use of substances.

Nurture. What are the environmental causes of mental illness? The development of mental illness can often be associated with one’s childhood experiences. Exposure to abuse is a potent example of an environmental factor that can lead to mental illness. Other experiences can also result in the onset of mental illness, including death, divorce, and/or other forms of grief or trauma.

In conclusion, neither Nature nor Nurture is solely responsible for the development of mental illness. Rather, genetic and biological factors combine with environmental and experiential factors to result in the onset of mental illness.
