Patients in their 50s who have chronic epilepsy seem to have cognitive deficits that may be linked to metabolic, inflammatory, and vascular abnormalities, according to a clinical study that included 40 patients with chronic localized epilepsy and 152 controls.
- To reach that conclusion, researchers conducted neuropsychological assessment, clinical examination, and blood testing to evaluate patients’ vascular status.
- The evaluation included systolic and diastolic blood pressure, body mass index (BMI), high density lipoprotein, homocysteine levels, and inflammatory markers including high-sensitivity C-reactive protein (hs-CRP), and interleukin-6.
- The metabolic assessment included measurement of insulin resistance by means of glucose levels and homeostatic model assessment of insulin resistance (HOMA-IR).
- Patients with epilepsy had impaired cognitive factor scores across the board.
- These patients also had abnormal BMI, hs-CRP, fasting glucose, and HOMA-IR.
- There was also a link between higher HOMA-IR and poor immediate memory and visuospatial ability.
- Elevated hs-CRP was associated with poorer visuospatial and verbal abilities.
