BENGALURU — In a significant clinical development for preventative neurology, a multi-year cohort study conducted by researchers at the National Institute of Mental Health and Neurosciences (NIMHANS) in Bengaluru has identified widespread dietary protein and folate deficiencies as primary, modifiable risk factors driving Cerebral Venous Sinus Thrombosis (CVT)—a devastating form of stroke predominantly afflicting adults between the ages of 18 and 45.
Published in leading peer-reviewed medical archives, the study tracked 320 consecutive patients diagnosed with angiographically confirmed venous strokes. The epidemiological data revealed that patients presenting with CVT were more than four times as likely to have severe dietary protein shortfalls and elevated plasma homocysteine levels (hyperhomocysteinemia) compared to age-matched healthy controls. Furthermore, concurrent moderate-to-heavy alcohol consumption was found to exacerbate vascular endothelial damage and accelerate pro-thrombotic cascades.
Unlike arterial strokes, which predominantly afflict older demographics with established hypertension and atherosclerotic disease, venous sinus thrombosis typically presents with persistent, worsening headaches, papilledema, and seizures—symptoms frequently misdiagnosed as tension headaches or migraines during initial primary care consultations. Lead investigators emphasised that prompt MR venography is vital in halting irreversible haemorrhagic venous infarction.
Public health experts point out that because hyperhomocysteinemia is largely reversible through targeted supplementation of bioactive folate (methylfolate) and vitamin B12 alongside balanced dietary protein intake, widespread awareness programs in primary healthcare centres could substantially curtail young-stroke incidence across southern Indian states.
