How Implicit Bias Leads to Misdiagnosis in Healthcare

Video summary

The video explores how implicit biases in healthcare can lead to the misdiagnosis of mental and behavioral disorders by overlooking the profound impact of socioeconomic factors on a patient's symptoms. The speaker argues that behaviors often interpreted as resistance, non-compliance, or pathology are frequently rooted in external circumstances such as poverty, limited education, or language barriers. For instance, a client falling asleep during group therapy might be mistakenly labeled as unmotivated rather than recognized as sleep-deprived due to working night shifts, while individuals with low blood sugar from food insecurity may exhibit irritability and an inability to focus that mimics ADHD or depression. Specific examples illustrate how diagnostic errors occur when clinicians fail to consider context, such as the case of children with dyslexia who are incorrectly diagnosed with oppositional defiant disorder because they struggle to read or participate in classroom activities. The speaker emphasizes that environmental toxins can cause confusion and brain fog that resembles early-onset dementia, while a lack of access to natural green spaces can trigger biochemical changes and behavioral symptoms similar to ADHD without the child actually having the condition. Furthermore, community violence and unstable housing create states of hyper-vigilance and chronic stress that manifest as defensive or acting-out behaviors, which are often misinterpreted as inherent personality disorders rather than survival responses to unsafe environments. The core conclusion is that effective diagnosis requires healthcare providers to step back and ask what else might be contributing to a patient's symptoms before jumping to pathological conclusions based on superficial characteristics. The speaker notes that middle-class practitioners may not immediately recognize these environmental stressors because they do not personally experience them, yet it is crucial to understand the culture, experiences, and realities from which clients emerge. By examining behavior within its full context—including factors like thyroid issues causing pain, poor sleep quality affecting cognitive function, and the specific challenges of limited English proficiency—clinicians can avoid mislabeling vulnerable populations and provide more accurate, compassionate care that addresses the root causes of distress rather than just treating perceived symptoms.

Think about how the following may cause symptoms or behaviors that are misdiagnosed as a mental or behavioral disorder or resistance to treatment based on people's implicit biases. You're working with somebody who lives in poverty. What assumptions do you make about them? What treatment How might treatment plans differ for this person? What about [snorts] people with limited education or limited English proficiency? How might your diagnoses be a little bit different? And when I worked in Florida, I worked at a a community behavioral health care center. Wonderful place. A lot of the people that we work with were impoverished and had limited education, but that didn't mean they were resistant. That didn't mean that they were um necessarily had any particular disorders besides obviously addiction that they were diagnosed with. It's important to look at behavior in context. If a client is falling asleep in group, if a client seems to be um resisting doing what you ask them to do or even become somewhat disruptive, we want to examine what is that behavior saying? For people with limited education, it may be saying, I don't understand. You're going too fast. You're using a lot of jargon. This is not useful to me and it's very frustrating. People with dyslexia often are misdiagnosed as having oppositional defiant disorder when they're children because in school they can't read uh as well as the other children or maybe they have difficulty with math and there's another word for that um, that I can't remember right now. But, instead of asking, "What is this behavior saying when this child refuses to participate in activities? When this child becomes agitated when they're told to sit at their desk and read an entire chapter in their social studies book?" What is that telling us? Um, have we screened for other issues, or are we jumping to the conclusion based on certain characteristics they have that they are being oppositional defiant? People who have shift or hourly work may have difficulty participating in treatment that's available during banker's hours. And if they are participating, maybe they work midnight shift and they have to come directly to group, then they start falling asleep in group. Are they being resistant? Are they unmotivated? No, they're sleep deprived. We need to step back and say, "What else could be causing this besides pathology?" People with poor health care access may have difficulty with a lot of things. If their thyroid is low, if they are in pain all the time, it's really hard to concentrate and be in a good mood when these things are going on. So, they may be more irritable. Um, environmental toxins can alter cognitive abilities. Um, people may show evidence of confusion and brain fog when exposed to environmental toxins. Does that mean they have early onset dementia? No, not at all. It means that they're having a toxic reaction. Lack of access to natural spaces. The research is just overwhelming that shows that when we're out in natural spaces, it helps regulate a lot of our biochemical processes. It reduces cortisol. It helps reduce blood pressure. They found that children who don't have access to natural spaces, green spaces, actually show more symptoms of behavioral issues and ADHD. That they don't have ADHD, they're ADHD-like symptoms. Um as opposed to children who do have access to those green spaces. And that was when they compared children who are in urban environments, even ones that have access to a park, but a park with no trees, no grass, no nothing, versus environments in which there's grass and trees and that sort of thing. So, that's interesting, but let's think about who lives in these really urban areas, and could that be contributing the the imbalance in the child's chemistry as a result of having a lack of access to natural spaces. Food insecurity. When you're hungry, it's difficult to focus. It's difficult to have energy. It's difficult to be motivated. If you're stressed about food, there may be hoarding of food. But generally, when we talk about food insecurity, we're talking about the result of being hungry. And think about yourself, and ways your behavior changes when your blood sugar is low. This isn't just be having a grumbly tumbly. This is having low blood sugar, not having enough calories to fuel your brain to help you do what you need to do. Community violence keeps people from feeling safe, keeps people from sleeping well, may keep people on edge and hyper-vigilant, which eventually can lead to irritability, um resistant behaviors, acting out behaviors. People become more stressed and more defensive. They stay in that stressed p- place and react from that stressed place when in general they feel like their environment is unsafe. And finally, unstable, crowded, or unsafe housing. If you can't get good sleep, it impacts every aspect of your being. It impacts you physically, it impacts you emotionally, cognitively, it impacts your relationships, your self-esteem, and can create a lot of other issues. People need adequate quality sleep in order to be able to function. When we are assessing somebody who is presenting with symptoms of depression or anxiety or ADHD or cognitive dysfunction of some sort, we need to back up and say, "What else might be going on for this individual that is contributing?" As, you know, a person of the middle class, I may not experience these things, so they may not be the things that first pop into my head. But it's important that we recognize the environment, the culture, the experiences from which our clients are emerging.
