This series highlights modern psychological problems that are often linked to modern foods and environmental toxins (which is not explained here from what I can see), which would explain why we didn't have problems like this until late 20th century. Before the second half of the 20th century there was a small % of such documented cases.
This series is intriguing and well done for what it is. But like a lot of docudramas it does focus on just a few people per episode who aren't necessarily train to do well behind the camera and can become annoying. It's interesting to see these people explain their circumstances and to hear the doctors try to identify them in such simplistic terms. As someone trained in psychology myself, from the '80s and '90s, these sound like people who don't really have a true connection with the human psyche. But that's just my personal opinion. There's one case here where a woman named Nicole couldn't interact with her mother or brother because of the way they use their hands or spoke. So, immersive therapy would work well for this type of situation since this form of OCD is really a form of control or need for power. The appropriate solution is to make sure her mother and brother do not keep coddling her need for them to be controlled by her OCD. But in the other case of the woman named Trina, who had thoughts of murdering strangers, I think immersive therapy is totally inappropriate. There are certain cases that are documented where the perpetrator had sought therapy and were sent away but then did commit the acts that were obsessing over. This includes Kaczynski and Whitman. I think it's totally inappropriate to treat someone with such violent obsessions as if they can be cured by immersive therapy.
They don't give any last names here so I don't have any way to see how Trina has done, but if she's not in some sort of psychiatric ward or in prison, I'd be surprised. These type of obsessive thoughts should be taken very seriously and not treated like mere thoughts.
And honesty, we all have thoughts that are obsessive about the way someone talks or eats or sleeps or sneezes or any number of things. We obsess over our addictions like smoking, eating, drinking, or obtaining attention from the opposite sex. Many of us spend more than 50% of our lives focused on these addictions - which we politely call addictions rather than obsessions.
I was raised in the '60s and the way we dealt with those things is to not placate a child who makes demands on others based on their inappropriate need for comfort derived from some action or inaction from anoher person. Accompanied by teaching them find something else to focus on, this was the basic tool for a lot if successful therapy in the 90s. They teach this in nicotine replacement therapy; when you want to have a cigarette, you have to make a plan of what you're going to do instead; so you might take up knitting or crossword puzzles or go for a walk or even recite a favorite poem or look at your goals list or any number of things. From the mid 20th century until now, we've allowed too many liberal minded ideas to become normalized into our society which coddle people regarding their personal opinions and idiosyncrasies instead of embracing the differences of family members and society members and accepting personal responsibility. This has become extremely problematic, as demonstrated on social media where people openly and frequently admonish, criticize, and blatantly bully people who have trouble expressing themselves, misspell words, misuse phrases, or whom they disagree with. This is a relatively new phenomenon that would never be acceptable in a real social environment such as school or business. Hopefully, it will be subsiding at this point as we begin reinstituting personal responsibility and weeding out food toxins and pharmaceutical toxins.
