Anaemia, alcohol major risk factors behind brain clots, finds ICMR study
An ICMR study identifies anaemia and alcohol consumption as primary risk factors for cerebral venous thrombosis (CVT) in India, differing from Western findings that emphasize hormonal and genetic factors. The study highlights a significant demographic trend, with young males being increasingly affected.
Why it matters
Understanding region-specific risk factors for stroke is critical for developing effective public health interventions and improving diagnostic awareness in different populations.
Anaemia and alcohol consumption have emerged among the leading risk factors of cerebral venous thrombosis (CVT), in contrast to Western studies where hormonal and genetic factors such as abnormal clotting of blood predominate, said an Indian Council of Medical Research-National Institute of Non-communicable Disease Epidemiology (ICMR-NINE).The CVT is a type of stroke that occurs due to a blood clot inside veins that drains blood from the brain.Of the 34,792 stroke cases registered in the hospital-based stroke registry (HBSR) from January 2020 to December 2022, 575 (1.6 per cent) cases were diagnosed with CVT and were included in the study.A majority of these patients -- 72.4 per cent -- were between the age of 18–44. Males constituted 60 per cent of the study population, while females accounted for 40 per cent; while 59.8 per cent of the patients were from rural areas.
