Pseudotumor Cerebri: Causes, Symptoms, and Prevention
Pseudotumor cerebri, also known as idiopathic intracranial hypertension, is a condition characterised by increased pressure around the brain, leading to headaches and vision problems. The exact cause remains unknown, but it may be linked to excess cerebrospinal fluid in the skull.
Symptoms of this condition include dull headaches, vision issues, tinnitus, nausea, vomiting, and dizziness. Certain medications, such as birth control pills, excessive vitamin A, tetracycline, and steroids, can increase the risk of developing pseudotumor cerebri. Other risk factors include young age, female gender, low BMI, pregnancy, chronic headaches, and use of specific medications like oral retinoids combined with tetracyclines. Obesity is a leading risk factor, with women under 44 being nearly 20 times more likely to develop it. Other health conditions like kidney disease, sleep apnea, Addison's disease, and Lyme disease can also increase the risk.
Diagnosis involves an eye exam, imaging tests like CT or MRI scans, and a spinal tap to measure spinal fluid pressure. Treatments range from medications like migraine drugs, glaucoma drugs, and diuretics to surgeries such as optic nerve sheath fenestration and spinal fluid shunt placement. Regular eye checks post-treatment are necessary to monitor vision, and weight loss can help prevent the condition.
Pseudotumor cerebri is a serious condition that requires prompt medical attention. Understanding its causes, symptoms, and risk factors is crucial for early diagnosis and effective management. Regular health checks and lifestyle modifications, such as maintaining a healthy weight, can help prevent this condition.
