Which brain-related symptom is associated with long-term cognitive effects after ICU stay?

• A. Brain Fog
• B. Delirium
• C. PTSD
• D. Depression

Answer: (A)

After an ICU stay, many survivors experience lasting cognitive difficulties such as trouble with attention, memory, and processing speed. This persistent brain fog reflects the ongoing cognitive effects that can follow critical illness and fits with post-ICU syndrome. Delirium, by contrast, is an acute, in-hospital confusion state; while it signals higher risk for later problems, it is not the long-term symptom itself. PTSD and depression can affect cognition as well, but brain fog specifically describes the enduring mental cloudiness people report after discharge. So the term brain fog best aligns with long-term cognitive effects after an ICU stay.
