Patients with migraines and patients classified as Caucasian had higher odds of being diagnosed with transient global amnesia (TGA), according to a recent study. All minority populations, however, showed a lower rate of diagnosis that fell short of statistical significance. Data were obtained from the Nationwide Inpatient Sample using ICD-9 and procedure codes. Descriptive and survey logistic regression analyses were conducted and adjusted for influence of comorbidities, demographic characteristics, and hospitalization-related factors. Researchers found:
- Patients with migraines were 5.98 times more likely to also have a diagnosis of TGA compared with patients without migraines.
- Similarly, patients with TGA were more likely to have hypertension, precerebral disease, and hyperlipidemia.
- The odds of being diagnosed with TGA was lower among African Americans and Hispanics as well as among patients classified as Asian/other, compared with Caucasians.
- TGA was associated with lower hospital charges ($14,242 vs $21,319), shorter hospital stays (mean days: 2.49 [SE=0.036] vs 4.72 [SE=0.025]), and routine hospital discharges (91.4% vs 74.5%).
