We asked Chat GPT to describe brain fog in chronic pain: What did we learn?

Introduction

Chat GPT is a generative artificial intelligence (AI) program: its recent introduction has created controversy in the academic world. ¹ Generative AI are electronic programs utilizing information from available databases to produce outputs similar to human actions and conversation. ¹ Similar to other forms of generative AI, Chat GPT works through synthesizing vast amounts of information across electronic databases and the internet, formulating seemingly accurate and convincing texts based on any question asked by the user. ¹ Researchers across diverse fields have discussed the utility of Chat GPT in 1) aiding in literature searches by identifying relevant sources, 2) quickly predicting trends in the data to support research decision making, and 3) summarizing and communicating information in an accessible and timely manner. ²

This commentary discusses the utility of generative AI to explore healthcare issues such as chronic pain and associated conditions. We present an example of Chat GPT 3.5, a free version, to illustrate potential applications. Further, the potential advantages and dangers of Chat GPT are described. The commentary concludes with recommendations for healthcare professionals considering use of Chat GPT.

Application

Given the posited practicality and usefulness of Chat GPT in research, we were curious to apply it to the context of our current research on brain fog in persons with chronic pain. ³ Brain fog lacks a formal definition, but is often described as a state of “mental cloudiness” characterized by fluctuating issues with attention, memory, and executive function. ⁴ Given that brain fog is a relatively new concept, we hypothesized an AI-generated description would be biased towards social and media discourses: however, the results were similar to both academic and media discourses we have read on the topic. Below we present three examples of questions we asked Chat GPT 3.5 and the answers we received (Table 1):

Question	Chat GPT answer
What causes brain fog in chronic pain?	As an AI language model, I do not experience pain or have personal experience, however, based on research I can tell that chronic pain itself can cause inflammation and impair brain function, leading to brain fog. The constant state of pain and discomfort can also cause sleep disturbances, which can further contribute to brain fog. Additionally, the use of pain medications and the stress of managing chronic pain can also impact cognitive function and lead to brain fog.
How can you measure brain fog in chronic pain?	As an AI language model, I don't have personal experiences, but I can share some scientific ways to measure brain fog: 1. Cognitive Tests: Medical professionals can conduct cognitive tests like the Montreal Cognitive Assessment (MOCA) or Mini-Mental State Examination (MMSE) to assess the cognitive abilities of an individual. These tests can measure attention, memory, language skills, and other cognitive domains. 2. Questionnaires: Health care providers can use questionnaires to measure the self-reported experiences of individuals, such as the Brain Fog Questionnaire (BFQ). 3. Neuroimaging techniques: MRI, fMRI, and PET scans are ways to measure the activity or blood flow to different areas of the brain. Certain brain areas like the prefrontal cortex or hippocampus can show reduced activity in individuals experiencing brain fog. 4. Biomarkers: Biomarkers such as cortisol levels, inflammatory markers, and hormones can also indicate the presence of brain fog.
Please provide the name of a questionnaire to measure brain fog	As of my last knowledge update in September 2021, there is a widely recognized or standardized questionnaire with a specific name designed exclusively to measure “brain fog.” However, researchers and healthcare professionals may use various existing assessment tools and questionnaires to evaluate cognitive function, mental clarity, and related symptoms that can be associated with brain fog. These assessments can include: 1. The Mini-Mental-State Examination (MMSE): Although primarily used to assess cognitive impairment and dementia, it can provide insights into cognitive function. 2. The Montreal Cognitive Assessment (MoCA): Similar to the MMSE, this test assesses various cognitive functions and may indirectly help identify cognitive difficulties. 3. The Patient Health Questionnaire-9 (PHQ-9): This questionnaire assesses depression symptoms, which can be associated with brain fog. 4. The Generalized Anxiety Disorder 7 (GAD-7): This measures symptoms of anxiety, which can also contribute to cognitive difficulties. 5. The Brief Cognitive Assessment Tool (BCAT): A cognitive screen tool used in various healthcare settings. Keep in mind that these assessments are not specific to brain fog but can help identify cognitive and emotional factors that may contribute to feelings of brain fog. Depending on the context and the patient's specific complaints, healthcare professionals may choose the most appropriate assessment tools. It's also worth noting that the field of healthcare and psychology is continually evolving, and new assessment tools may have emerged since my last update. Always consult with a healthcare professional for the most up-to-date and appropriate assessments and interventions for cognitive issues or brain fog.
How can healthcare professionals treat brain fog in chronic pain?	As an AI language model, I do not have personal experiences, but I can provide a general answer to your question. Brain fog, which refers to a cognitive impairment characterized by confusion, forgetfulness, and difficulty concentration, is a common symptom associated with chronic pain. Healthcare professionals may use various strategies to help manage brain fog in patients with chronic pain including: 1. Pain management: reducing the intensity of chronic pain through pharmacological and non-pharmacological approaches to help alleviate brain fog in patients with chronic pain. 2. Cognitive behavioral therapy: this approach helps patients learn how to manage their pain-related thoughts and behaviors, which can help them focus better and reduce the impact of brain fog 3. Exercise: regular physical activity can improve brain function and reduce the risk of developing cognitive impairment associated with chronic pain 4. Nutritional therapy: some dietary changes, such as increasing protein intake and reducing sugar and carbohydrates, may help alleviate brain fog in chronic pain patients 5. Medication review: healthcare professionals may review all medications a patient with chronic pain is taking, as some drugs have side effects that can cause brain fog 6. Sleep management: patients with chronic pain may experience sleep disturbances that exacerbate brain fog. Healthcare professional may help regulate sleep hygiene or provide medication to improve sleep quality. Overall, treating brain fog in chronic pain requires a comprehensive approach that addresses both the physical and emotional aspects of chronic pain.

Discussion

The responses provided by Chat GPT are consistent with existing literature, illustrating both the potential benefits and pitfalls of adopting the technology within healthcare and research. Some responses were accurate, suggesting utility for information seeking by healthcare professionals. For example, Chat GPT was able to synthesize potential causes of brain fog identified in the literature, such as inflammation, sleep, and pain medications,^5–7 and suggested plausible, if generic, management approaches. However, when asked how to measure brain fog, Chat GPT did not generate a single accurate response. There is no such thing as the “Brain Fog Questionnaire” and we are unaware of neuroimaging or biomarker studies within the context of brain fog. ³ Also, a study investigating long-COVID-related brain fog found that the MoCA was not sensitive enough to detect cognitive changes in persons with long COVID ⁸ ; this is concordant with the mixed findings of earlier studies using such tools to investigate “fibrofog.” ³ Chat GPT may also have inconsistencies in responses as when provided with a more specified question: “please provide the name of a questionnaire to measure brain fog,” Chat GPT addressed that there were no specific measures of brain fog, but provided examples of existing measures of cognition. Interestingly, we noted Chat GPT was most accurate when describing topics which have been increasingly investigated, such as potential causes. Chat GPT is least accurate when responding to inquiries that are least investigated (e.g., measurements of brain fog). This illustrates the dependence of Chat GPT on the quality and quantity of information existing on a given topic, and its tendency to “confabulate” when information is lacking.

Recommendations

Given the potential strengths and limitations of Chat GPT we have developed four recommendations for use by healthcare professionals and researchers:

Chat GPT should be used with caution as a starting source to facilitate the search of information. Chat GPT can provide a brief and accessible synthesis of the literature that may help guide healthcare professionals to form a foundational understanding of a well-established topic or phenomenon, akin to having a reference textbook that is constantly updating itself. This may improve evidence-informed practice by facilitating time-consuming searches for relevant sources of information synthesis in busy and under resourced health care settings. ⁹ However, given the potential for imprecise or fictitious results from generative AI, critical reading, and triangulation of outputs through peer debriefing or additional sources are required.

Conclusion

To conclude, as AI-driven technologies like Chat GPT become increasingly available and trusted in our society, so does the importance of our awareness for both benefit and potential for harm when AI is used for non-critical information seeking and self-education.
