Question

Quizplus · Accepted Answer

The sudden onset of specific cognitive impairment and difficulty in speaking is more indicative of a stroke, which can cause vascular neurocognitive disorder. Creutzfeldt-Jakob disease and Huntington's disease are both degenerative neurological disorders that tend to have a more gradual onset of symptoms. Mercury poisoning may cause a wide range of symptoms, but would generally not cause such specific cognitive impairment and difficulty in speaking without affecting other cognitive functions as well.
