In brief: Possible delirium
Dear karthika, because your father's current symptoms are preceded by the fever and headache, he could have a medical condition changing his behavior. Sudden and acute onset, alteration in attention, and fluctuating course are the central features of delirium, which can be caused by a wide variety of things including meningitis and drug intoxications.
He needs emergency evaluation.
