Melissa Walker is a therapist who uses art to help servicemen and women work through PTSD trauma. Trauma affects the area of the brain that creates speech, which makes it difficult for sufferers to express what haunts them. Interestingly, the process of creating art bypasses the language center of the brain, helping people work through trauma in a non-verbal, non-threatening way. Then they can use words to describe their art, thus helping them finally talk about their trauma. Thanks to Melissa’s program, service members can finally express themselves for the first time in years—even decades. Once they can do this, they can finally start to heal.
