Thank you very much for posting this question in HCM
Let me tell you that any symptom in medicine can be due to various causes and the primary objective of the rerating doctor is to establish the cause and deal accordingly.
Note that there are various types of brain tumor
and it can be diagnosed by MRI
scan of brain. The long term outcome of a patient with brain tumor depends upon the type and stage of the tumor. The symptoms of brain tumor largely depend upon its location. It may cause the symptoms that you have told. It may cause weakness of hands or legs or epilepsy
. In the absence of the exact description of tumor, MRI or any histopathology data it will be difficult to predict the longevity of patients with brain tumor.
I will advise you to get re-examined by a local neurosurgeon, and get all her medical records examined too. This will give you an idea of her prognosis. Further I will also advise you to take a medical oncology opinion if any definite treatment can be offered.
Hope this will help you
