| 1. | When Jeanie was a child she experienced intense periods of stress and trauma. As an adult, she struggles with severe depression. Despite using multiple prescription anti-depressant medications, Jeanie does not find any one of them to be significantly effective. Which of the following best describes what has happened to Jeanie's brain? |
The early developmental stress Jeanie experienced caused the neural connections in her hippocampus to stunt growth, resulting in a smaller than average hippocampus. Antidepressants are ineffective initially because Jeanie's brain needs more neurogenisis in her hippocampus to assist with her mood.
The early childhood stress Jeanie experienced caused her limbic system to rewire it's route through her brain. Therefore, the anti-depressants are effecting a part of her brain that she does not currently have access to and becoming ineffective.
None of these
Jeanie's brain is overproducing the neurotransmitters that the anti-depressant is delivering. Instead of decreasing Jeanie's depression, it is intensifying it by producing more of what she already has.
Jeanie's brain is not receptive to the type of neurotransmitter being delivered by the anti-depressant. Jeanie needs an anti-depressant that delivers a different combination of neurotransmitters than the ones she has already tried.
