RECOGNIZE THE SIGNS
Delirium looks different in every person. Knowing what to look for, and what questions to ask, can be the difference between recovery and permanent decline.
THE MOST IMPORTANT CLUE: HOW FAST DID IT START?
Delirium comes on suddenly, hours to days. Dementia develops over months and years. If a senior's behavior or cognition has changed noticeably in the last 24–72 hours, that is a medical emergency until proven otherwise.
Delirium
Hours to days
Sudden, acute change. The person you knew yesterday is not the person in front of you today.
Dementia
Months to years
Gradual, progressive decline. Changes are slow and consistent over a long period.
Depression
Weeks to months
Persistent low mood, withdrawal, loss of interest. Does not fluctuate dramatically hour to hour.
TWO TYPES — ONE IS ALMOST ALWAYS MISSED
Hyperactive Delirium
Agitation, combativeness, pulling at IVs, shouting, hallucinations, paranoia. This type gets attention because it demands it.
- →Agitation and restlessness
- →Combative or aggressive behavior
- →Hallucinations (seeing or hearing things)
- →Paranoia and extreme fear
- →Pulling at tubes, IVs, or clothing
- →Shouting or calling out
Hypoactive Delirium
Quiet, withdrawn, sleeping more than usual, slow to respond, staring blankly. This type is mistaken for tiredness, depression, or 'just getting old.' It accounts for up to 75% of delirium cases and is far more likely to be missed.
- →Unusual quietness or withdrawal
- →Sleeping far more than normal
- →Slow or absent responses to questions
- →Blank staring, 'not there' expression
- →Refusing food or drink without explanation
- →Seeming 'out of it' or heavily sedated
RED FLAG CHECKLIST
If you can answer YES to the first question AND yes to any of the others, demand a delirium assessment immediately.
Has there been a sudden change in mental status in the last 24–72 hours?— KEY QUESTION
Is the person confused about where they are or what day it is?
Are they having trouble focusing or following a conversation?
Has their behavior changed dramatically from their baseline?
Are they seeing or hearing things that aren't there?
Are they unusually sleepy, withdrawn, or unresponsive?
Have they had a recent infection, surgery, hospitalization, or medication change?
Are they expressing fear, paranoia, or a wish to die?
WHAT TO SAY TO THE MEDICAL TEAM
Families are often dismissed. Use these exact phrases to demand action.
"I need a delirium assessment performed using the CAM tool."
The Confusion Assessment Method is the gold standard. Ask for it by name.
"This is not their baseline. This change happened in the last [X] hours."
Establish the timeline clearly. Delirium is defined by acute onset.
"Please rule out a urinary tract infection before any psychiatric referral."
UTIs are the most common and most missed trigger in elderly patients.
"Can you review all medications for known delirium risk in elderly patients?"
Many common drugs — including some sleep aids, antihistamines, and bladder medications — are high-risk.
"I am not leaving until someone explains what is causing this change."
You have the right to advocate. Use it.
