Serious condition. Sir , the problem is!

Hello sir , The problem is regarding my sister health . She is 28 years old. Couple of days back she complained about headache for 3 to 4 days and later she started behaving strangely that she is not able to remember us and even her name later she went into serious condition that she stopped taking food and even she went through some severe seizures that she herself bitten her lips and tounge and she even got fits and now she in critical care unit . I tried to reach to consultation through practo but I am unable to complete payment method. We even unable to bring the patient. I live in USA. The doctor told us the problem is due to blood and spine infection. We are pretty much confused wat actual problem is and she is absolutely healthy before this happend. Can u plz provide me some means so that I can reach through any source regarding problem as my parents are unable figure this out . Even I had her MRI and other test reports plz give me away to reach u as she is criticalconditio
