Shafaqna India: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. The incidence of CVT-related stroke among men has further shown an increasing trend in recent years.
According to the study, “A striking sex difference was noted, with anaemia, pregnancy and oral contraceptives/hormone therapy-related risk factors more common among women, whereas alcohol and tobacco use were predominant among men.”
