Lyra has an anxiety disorder along with noise sensitivity and aversion — both innate and worsened by experience. She is behaviourally abnormal in her intensity and reactivity.
Lyra will never be “cured.” Her quality of life will be limited by her temperament, learning, and emotional/mental health issues. The goal is to prevent further setbacks by reducing exposure to triggers, and to use reward-based training and counter-conditioning to improve her responses to those triggers. Medication may help in her training. We must keep in mind that her behaviour may grow more intense and that new issues may arise as she matures.
In other words, we are looking at a future of 1) management, 2) behaviour modification, 3) and medication — at least for now — to give her an acceptable quality of life.
