Hi, My Dad, After Flu Like Symptoms, Is Hospitalized Due
A correct diagnosis is mandatory. Treatment is mainly supportive.
Detailed Answer:
Hello and welcome to " Ask a Doctor" service.
I have read your query and here is my advice.
Since there was a fever, an infection is very likely.
A brain MRI may give more information about any possible diagnosis such as encephalitis, etc. in such a case.
A spinal tap (lumbar puncture) with subsequent cerebrospinal fluid examination also may be necessary.
Treatment, until a correct diagnosis is mainly supportive, oxygenation, blood pressure, and blood sugar levels should be maintained within normal ranges.
Antibiotics and antivirals also may be considered to be used.
The drugs you provided are a supplement for the brain and antivertiginous.
Discuss with a Neurologist for these issues.
Hope this helps.
Feel free to ask if you have further questions.
