Which of the following is NOT a sign of stroke?

The correct answer is that a severe headache with fever is not typically recognized as a sign of a stroke. While it is true that headaches can occur with certain medical conditions, a stroke is more commonly associated with a sudden loss of function or changes in physical condition rather than with fever.

Signs of stroke primarily stem from the rapid onset of neurological deficits, which are well captured in the other options. Arm weakness indicates a loss of strength that may occur if one side of the brain is affected, typically leading to weakness on the opposite side of the body. Sudden confusion reflects impairments in cognitive function, which can result from blood flow interruption to areas of the brain responsible for cognition. Face drooping is a classic symptom, often assessed using the smile test to detect potential asymmetry resulting from stroke-induced muscle weakness.

Therefore, while severe headache with fever might suggest other medical issues, such as an infection or a different neurological condition, it does not align with the acute and specific symptoms associated with a stroke.
