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.

Marijuana and The Brain

By: Tori Ling

            Today, Marijuana has grown tremendously in popularity, but as a relatively new drug, are we sure what it is doing to our brains? According to the CDC, short-term effects of cannabis (within 24 hours of usage) include immediate impact on thinking, attention, memory, coordination, movement, and time perception. Long-term effects of cannabis can affect memory, attention, and learning. Using Marijuana before the age of 18 is especially harmful for the developing brain and can lead to permanent deficits (as listed above).

            In contrast, Harvard’s MIND investigated a longitudinal observational study of individuals using medical cannabis for various conditions and symptoms. Participants chose their own cannabis product, and were evaluated performing tasks at 3, 6, 12, 15, 18 and 24 months after their treatment begun. The results found that the patients using medical marijuana actually had better performance on cognitive tasks requiring executive function over time. Patients also described their improved mood, energy, sleep, and reduced use of conventional medications. Patients included in this study were generally above the average recreational use age. There has been preclinical data suggesting that cannabis may help boost the body’s aging endocannabinoid system. (The endocannabinoid system (ECS) is a crucial, complex cell-signaling network in mammals that maintains homeostasis by regulating mood, sleep, appetite, pain, and immune responses. When activated, it helps manage stress and physiological balance. )

            The National Institute of Health (NIH) states: “Adult chronic cannabis users with healthy controls, neural activation was measured in paradigms including tests of attention, cognitive controls, memory, decision-making, motor performance, and affective processing. Most studies have found changes in brain function, often without notable performance deficits” the NIH found that Schizophrenia patients who reported abusing cannabis actually had a better memory than those who were not using cannabis from Marijuana potentially reducing negative symptoms.

            Overall, Cannabis is not recommended for anyone under the age of 21, as it can cause permanent harm to your brain and its functions, but studies have found no evidence that adolescent cannabis use or dependence are associated with IQ decline or neurocognitive performance . However, Marijuana can be beneficial to those suffering from some chronic conditions. THC can “promote neurogenesis, restore memory and prevent neurodegenerative processes and decline in animal models of Alzheimer’s disease.” (National Institute of Health). THC can modulate memory and cognition in an age-and-dose dependent manner. Marijuana should be used on a case by case basis after being evaluated by a medical professional.
