**How to Spot and Handle Drug-Induced Delirium in Dementia**
Drug-induced delirium is a sudden, severe confusion that can happen when medications affect the brain. For people with dementia, this risk is higher because their brains are already vulnerable. Here’s how to recognize it and what to do:
—
### **What Does Drug-Induced Delirium Look Like?**
– **Sudden confusion**: A person might forget where they are or struggle to follow conversations.
– **Agitation or aggression**: Unusual restlessness, yelling, or physical outbursts[1][4].
– **Sleep changes**: Sleeping during the day but awake and disoriented at night[5].
– **Hallucinations**: Seeing or hearing things that aren’t there[1].
Unlike dementia symptoms (which worsen slowly), delirium comes on fast—often within hours or days[5]. If you notice these changes after starting a new medication, suspect drug-induced delirium.

### **Common Culprits**
Many medications can trigger delirium in dementia patients:
– **Painkillers** like opioids (e.g., morphine).
– **Anticholinergics**, including some allergy meds (e.g., diphenhydramine) or bladder drugs.
– **Benzodiazepines** (e.g., lorazepam) for anxiety[4][5].
Even antidepressants like citalopram may cause agitation in some cases[4]. Always review medications with a doctor if behavior changes suddenly.

### **What You Can Do Immediately**
1. **Stop new medications temporarily**: If a drug was recently started, ask the doctor if it’s safe to pause it while evaluating symptoms[4][5]. *(Never stop without medical advice.)*
2. **Check for infections**: Urinary tract infections (UTIs) often mimic delirium but require different treatment[1][5]. A simple urine test can rule this out.
3. Simplify surroundings: Reduce noise and clutter to ease confusion[4][5]. Keep lights dim at night to prevent sleep disruptions.

### Medical Treatment Options
Doctors may recommend:
– **Switching medications**: Safer alternatives like Rexulti (brexpiprazole), which is FDA-approved for Alzheimer’s-related agitation, might help without worsening confusion[4].
– Short-term use of antipsychotics (**only if severe**) such as risperidone—but these carry risks like stroke in dementia patients and should be used cautiously[4][5].
Non-drug approaches like calming music or gentle massage are often tried first to avoid side effects[4][5].

### Prevention Tips
To reduce future risks:
✔️ Keep an updated medication list and share it with all healthcare providers before starting new drugs—even over-the-counter ones!
✔️ Avoid “as-needed” sedatives unless absolutely necessary; they increase fall risks and confusion in dementia patients [4][5]
✔️ Monitor hydration and nutrition; dehydration worsens delirium [1]
Delirium recovery can take weeks but acting quickly improves outcomes significantly [1] Always involve a geriatric specialist who understands both dementia care AND medication safety nuances unique to older adults!
