- Blood clotting disorders: Inherited or acquired conditions that affect the normal clotting process can increase the risk of CVT.
- Dehydration: Reduced fluid intake or excessive fluid loss can contribute to the development of blood clots.
- Infections: Certain infections, such as sinusitis, meningitis, or ear infections, can lead to inflammation and clot formation.
- Trauma: Head injuries or trauma to the brain can disrupt blood flow and cause clots to form.
- Pregnancy and postpartum period: Hormonal changes and altered blood flow during pregnancy and after childbirth can increase the risk of CVT.
- Hormonal factors: Use of oral contraceptives or hormone replacement therapy, especially those with high estrogen content, can raise the risk.
- Cancer and malignancies: Some cancers, particularly those involving the brain or blood, can predispose individuals to CVT.
- Inflammatory conditions: Autoimmune disorders like systemic lupus erythematosus (SLE) can increase the risk of clot formation.
Symptoms:
- Headache: Often severe and may worsen over time.
- Visual disturbances: Blurred vision, double vision, or loss of vision in one or both eyes.
- Seizures: Especially in the early stages of CVT.
- Focal neurological deficits: Weakness, numbness, or tingling in specific body parts.
- Altered mental status: Confusion, drowsiness, or coma.
