White matter lesioning associated with metabolic syndrome in middle age.

White matter lesions in a 57 year old with a BMI of 36, hypertension (135/100), and diabetes type 2 (HbA1c = 7.6). Vascular risk factors are associated with white matter lesions, which negatively correlate with cognition. Hawkins et al. Metab Brain Dis, 32(3), 849-857. doi: 10.1007/s11011-017-9980-9
