The effects of carbon monoxide toxicity on cognitive deficits may include:

Visual impairments
Memory and attention issues
Severe fatigue
High blood pressure

The correct answer is: Memory and attention issues

The impact of carbon monoxide toxicity on cognitive deficits prominently encompasses memory and attention issues because carbon monoxide binds with hemoglobin in the blood, reducing oxygen delivery to the brain and other vital organs. This oxygen deprivation can disrupt normal brain function, leading to difficulties in cognitive processes, particularly in areas involving memory retention and attentiveness. Cognitive deficits may manifest as challenges in recalling information, sustaining focus on tasks, and overall decreased cognitive performance. The intricate relationship between oxygen levels and brain function highlights why individuals exposed to carbon monoxide may struggle with these specific cognitive areas more than other symptoms related to physical health or other cognitive domains like visual impairments or physical fatigue. While severe fatigue is indeed a possible symptom of carbon monoxide exposure, it is more of a physical response rather than a direct cognitive deficit. Visual impairments and high blood pressure can be associated with carbon monoxide toxicity but do not specifically point to the cognitive deficits associated with this condition.
