**Managing Dementia-Related Hallucinations and Delusions with Medication**
Dementia-related hallucinations (seeing/hearing things that aren’t there) and delusions (false beliefs) can be distressing for both patients and caregivers. While medications can help, they require careful use to balance benefits and risks. Here’s a straightforward guide:
—
### **1. Cholinesterase Inhibitors: First-Line Treatment**
Drugs like **donepezil (Aricept)** or **rivastigmine (Exelon)** are often tried first, especially for Lewy body dementia[4]. These improve alertness, reduce confusion, and may lessen hallucinations by boosting brain chemicals involved in memory[3][4]. They don’t cure dementia but can stabilize symptoms temporarily.

### **2. Antipsychotics: Use With Extreme Caution**
Antipsychotics like **quetiapine (Seroquel)** or **olanzapine (Zyprexa)** are reserved for severe cases where safety is at risk[1][5]. They calm agitation or paranoia but carry serious risks:
– **Side effects**: Drowsiness, weight gain, higher stroke risk[1].
– **Special warning**: Avoid older antipsychotics like haloperidol—they can worsen symptoms or even be fatal in Lewy body dementia[4][5].
*Example*: Olanzapine may help nighttime delusions better than risperidone in Alzheimer’s patients but still requires close monitoring[2].

### **3. Parkinson’s Medications: A Double-Edged Sword**
For Lewy body dementia with movement issues, drugs like **carbidopa-levodopa** might help stiffness but could trigger hallucinations if overused[4]. Doctors start at very low doses to avoid this trade-off.

### Key Tips for Caregivers
– **Track changes**: Note when hallucinations occur—medication timing might need adjustment.
– **Avoid triggers**: Poor lighting or loud noises can worsen symptoms without medication changes.
– **Prioritize non-drug approaches**: Calm reassurance (“I don’t see it either, but I understand you do”) often reduces distress before meds are needed[1][4].
Always work with a specialist to tailor treatments—what works for one person could harm another depending on their dementia type and health history[5][4].
