My overall reaction to Dr. Heilbrun’s testimony is that, with the important exception of his repeated reliance on “mortal sin”, he appeared fair, neutral, and methodical.
Of the experts we have heard from, I believe he looked at Lindsay most holistically. He considered who she was before Callan, what was happening in the months leading up to January 24, and her mental state since. He diagnosed her with bipolar II, which multiple clinicians considered and appears plausible based on the testimony. He also acknowledged her current suicidality, even when the prosecution seemed reluctant to move into her present condition.
Today, he discussed peritraumatic dissociation: disconnection from one’s body, emotions, surroundings, or reality during or around a traumatic event.
I know derealization and depersonalization personally. Many women with pmdd or premenstrual exacerbation have also described feeling detached from themselves, unreal, outside their bodies, or unable to access their emotions during their deepest depressive episodes, often in the final 1 to 3 days before their periods.
However, dissociation is not psychosis, but it is a significant altered state of consciousness.
We do not have Lindsay’s last menstrual period or enough cycle data to place January 24 within a hormonal phase. We cannot turn thought into fact or create wild theories.
This testimony reinforces why I continue asking about her cycle, nutritional status, weight loss, medications, sleep, and metabolic health. The brain does not exist separately from the body. Could multiple contributing factors have pulled her further into a depressive or dissociative state?
I believe women often recognize that something inside them has shifted before they understand what the signal means. Intuition can be powerful, although it can also become distorted when someone is severely unwell. It should invite careful investigation by not only the woman, but also by per providers, not automatic dismissal, as Dr. Mack’s testimony illuminated.
I believe what we learn from this tragedy may help prevent the next one.
