Thanks for your health concerns. Recent advances in Neurology have identified that permisive hypertension
, meaning allowing the blood pressure to be between 160-180 after an ischemic stroke
might improve chances of recovery; we used to try do control blood pressure aggressively and patients did not do better.
In terms of the temperature change, it could be circumstantial, but patients after stroke can have disregulation of temperature, heart rate
, blood pressure and other functions that are brain dependant but automatic
Hope this is useful, wish you and your father the best,
