Objective:
Migraine is one of the leading causes of disability worldwide and a recognized contributor to health disparities with public health implications. Although migraine is a highly prevalent neurological condition, research on the cognitive manifestations of migraines is inconsistent. Studies have confirmed neurocognitive compromise during the presence of a migraine attack, with it’s onset and frequency being associated with greater cognitive decline. Research on the cognitive implications of migraines in underserved communities is scarce. The American Migraine Prevalence and Prevention Study (2015) found that the prevalence of chronic migraines was the highest amongst Hispanic females compared to White females. Latina/os are 50% less likely to receive a migraine diagnosis and adequate headache medication when compared to non-Hispanic White patients. Latina women were more likely to report somatic symptoms than White and African American participants (F=8.96; p>0.001) (Liefland et al., 2014). Somatoform disorders are often diagnosed amongst Latina/os to account for medical unexplained symptoms, and if misdiagnosed can be stigmatizing and detrimental to treatment. We illustrate the critical role that neuropsychologists play by utilizing Socially Responsible Neuropsychology (SRN), a theoretical framework that promotes equitable and precise neuropsychological care to reduce misdiagnosis, elucidate cognitive implications, and address the complex medical needs of Latina/o/ patients. Given the limited literature on migraines and neurocognitive functioning, our objective is to present two case studies to illustrate the neuropsychological implications among bilingual Latina/o with chronic migraines.
Participants and Methods:Two highly educated Latina/o women, ages 39 and 41 years old, with chronic migraines, cognitive decline, diagnoses and a history of somatization symptoms. The onset of symptoms was gradual, worsening in intensity and frequency, along with notable motor symptoms (e.g., paralysis, weakness, numbness, bilateral tremors), photophobia, and phonophobia. Their cognitive complaints were conceptualized as part of a somatoform presentation by their providers.
Results:The SRN model guided clinical decision-making to establish reliable normative anchors to identify relative impairment compared to premorbid estimates. Testing was completed in English after establishing language dominance via English and Spanish measures of verbal fluency. Cognitive profiles identified declines in attention, processing speed, language, perceptual reasoning, visual memory, executive functioning, motor functioning, and notable decline in their functioning over several years. The neuropsychological profile discounted the presence of a somatoform disorder. One case was diagnosed with an Unspecified Mild Neurocognitive Disorder, while the other case met criteria for a Major Neurocognitive Disorder due to Multiple Etiologies (i.e., vascular contribution, migraines, history of other contributions- choking episode).
Conclusions:Given the decline in each profile, it was hypothesized that the patients’ utilization of compensatory strategies and higher education may have masked the onset of symptoms. These complex cases highlight the need for comprehensive neuropsychological evaluations that are culturally and linguistically responsive to boost the sensitivity of accurate diagnosis. The ability to objectively capture neurocognitive decline offers a unique opportunity to enhance treatment, which would have otherwise remained undetected and untreated. The SRN model enhanced diagnostic considerations, treatment planning, and allowed for advocacy strategies to improve the quality of life, and access to culturally/linguistically appropriate resources.

Objective:
In the wake of the national controversy over demographically corrected normative comparisons used in neuropsychological assessment, the field finds itself in need of adopting better practices and providing stronger instruction in norm selection and application when assessing underrepresented populations. Neuropsychologists must employ critical thinking within their clinical decision-making that takes into account patient demographics, analysis of the measures themselves, normative samples, and statistical adjustments employed in normative studies. Not doing so may result in erroneous diagnostic conclusions, exposing underserved patient populations to poor or harmful clinical care and even misdiagnosis. The following case series presents several demographic considerations illustrating how selection and application of different (at times, ill-fitting) normative reference groups can affect treatment outcomes in the Latinx community. We examined the performance of various published norms when applied to monolingual and bilingual Spanish speakers.
Participants and Methods:This study samples three demographically diverse (i.e., education, age, and sex) clinical cases and applies regression-based and stratified norms to raw scores to demonstrate the possible differential outcomes when using different reference groups. One example is Ms. Congeniality, a 69-year-old, Spanish and English bilingual woman with 12 years of education who presented for a third revaluation at our clinic due to progressive memory loss. Her prior Spanish language profiles demonstrated impaired confrontation naming and steadily decreasing letter fluency over the past 10 years.
Results:Her performance on semantic fluency (i.e., animal naming) showed relative stability based on her raw scores (10 in 2012, 11 in 2016, and 12 in 2022). Using the Neuropsi A&M norms, which stratify performance across nine age ranges between ages 6-85 and three education ranges between 0-10+ years, her performance over the past 10 years ranged between the less than 1st percentile to the 9th percentile (1%, 1%, and 9%, respectively). However, using the NP-NUMBRS norms, which use regression-based continuous age (19-60) and education (0-20) predictors of test performance, her scores corresponded to steadily improved performance (8%, 28%, and 86%). Thus, this qualitative comparison demonstrates a likely overcorrection for individuals of advanced age when using norms based on samples that are a poor fit because they lack representation of older adults, as in NP-NUMBRS, and a possible undercorrection when using norms with overly broad education stratifications (e.g., 10-22 years, as in Neuropsi).
Conclusions:Application of ill-fitting normative standards can have far-reaching implications for interpretation of neuropsychological test results. Moreover, this case series exemplifies the need for higher-order instruction in norm selection, specifically for underserved communities who run the risk of being misdiagnosed. Through case examples, this study underscores the importance of understanding the unique effects of different demographic corrections in the context of limited available normative reference groups. This abstract is the first illustration in a series of papers aimed at facilitating the decision-making process within the framework of socially responsible neuropsychological practice.

Objective.
The National Neuropsychology Network (NNN) is a multicenter clinical research initiative funded by the National Institute of Mental Health (NIMH; R01 MH118514) to facilitate neuropsychology’s transition to contemporary psychometric assessment methods with resultant improvement in test validation and assessment efficiency.
Method:The NNN includes four clinical research sites (Emory University; Medical College of Wisconsin; University of California, Los Angeles (UCLA); University of Florida) and Pearson Clinical Assessment. Pearson Q-interactive (Q-i) is used for data capture for Pearson published tests; web-based data capture tools programmed by UCLA, which serves as the Coordinating Center, are employed for remaining measures.
Results:NNN is acquiring item-level data from 500–10,000 patients across 47 widely used Neuropsychology (NP) tests and sharing these data via the NIMH Data Archive. Modern psychometric methods (e.g., item response theory) will specify the constructs measured by different tests and determine their positive/negative predictive power regarding diagnostic outcomes and relationships to other clinical, historical, and demographic factors. The Structured History Protocol for NP (SHiP-NP) helps standardize acquisition of relevant history and self-report data.
Conclusions:NNN is a proof-of-principle collaboration: by addressing logistical challenges, NNN aims to engage other clinics to create a national and ultimately an international network. The mature NNN will provide mechanisms for data aggregation enabling shared analysis and collaborative research. NNN promises ultimately to enable robust diagnostic inferences about neuropsychological test patterns and to promote the validation of novel adaptive assessment strategies that will be more efficient, more precise, and more sensitive to clinical contexts and individual/cultural differences.
