Assessment and Grading

Characterize the symptom (onset, pace)

Ask the patient:

Have you had any issues with feeling cloudy or confused in the past? Is this a new or worsening symptom? When did it start or get worse? Has it developed gradually or suddenly?

Grade the symptom

Ask the patient:

How disoriented/cloudy do you feel? Does it come and go? Is it affecting your ability to take care of yourself?

Patient Query Regarding Other Symptoms/Red Flags

Ask the patient:

Any problems with eating/drinking? How much fluid are you drinking per day?

Do you have any new or worsening head pain with vision changes, fever, nausea, or vomiting while feeling confused or tired?

Do you have a headache plus a stiff neck? Have you had any sleepiness, hallucinations, seizures?

Patient Factors to Consider That Affect the Approach to Intervention

Consider the following in individualizing the intervention: Is the patient a good or poor historian? Any language barriers or cognitive deficits? Is the patient reliable (able to carry out treatment recommendations)? Does this patient have alcohol/substance abuse issues? Does the patient have transportation? Is there sufficient caregiver support?
