Welcome to Health Care Magic
Your mother has sustained a stroke
...She needs MRA / She should be seen and followed up by a Neurologist
You have not stated her personal habits, family history, or co-morbidities...which could have an influence on the diagnosis and outcome...It does not seem reasonable or realistic to suggest some suitable solutions, with this inadequate information provided here... One does not treat a CT scan
or lab – the patient as a whole needs care... Follow up with neurologist.
Wishing speedy recovery
