Final answer:
The symptoms described are consistent with PTSD, affecting regions of the brain involved in emotions and memory, and the type of memory affected is traumatic memory.
Step-by-step explanation:
The symptoms described in the question, such as hyperarousal, avoidance behaviors, and re-living of an experience, are consistent with the diagnosis of Post-Traumatic Stress Disorder (PTSD). PTSD is a mental health condition that can occur in individuals who have experienced or witnessed a traumatic event, such as a bad breakup. The symptoms typically last for more than a month and can significantly impact a person's daily life.
In terms of the regions of the brain that are likely to be affected by the antibodies from the patient's immune system, research suggests that the amygdala, hippocampus, and the prefrontal cortex may play a role in the development of PTSD. These regions are involved in processing and regulating emotions, as well as encoding and retrieving memories.
The type of memory affected in PTSD is traumatic memory. Traumatic memories are often vivid and can lead to the re-living of past traumatic events, causing distress and hyperarousal. It is important for individuals experiencing these symptoms to seek professional help, as treatment options are available to manage and alleviate the impact of PTSD.
