The First Step: Non-Pharmacological Strategies
Before considering medication, healthcare providers and caregivers focus on non-drug interventions to address restlessness and agitation. Many behavioral symptoms are a response to a person's inability to communicate discomfort, confusion, or unmet needs. A person-centered approach is key to identifying and mitigating these triggers.
- Environmental Modifications: A calm, familiar, and predictable environment can significantly reduce anxiety. This includes reducing clutter and noise, providing comfortable lighting, and keeping familiar objects nearby. Shadows in the evening can be particularly confusing and may trigger sundowning, so ensuring rooms are well-lit is important.
- Structured Routines: A consistent daily schedule for meals, bathing, and activities can provide a sense of security and reduce uncertainty. Engaging in regular, light physical activity, such as walks, can also help improve sleep quality and reduce restlessness.
- Communication and Validation: Approaching the individual with a calm and friendly demeanor, validating their feelings without correcting them, and offering reassurance can de-escalate situations. Sometimes, simply acknowledging their distress can help.
- Sensory Stimulation: Engaging the senses can be calming. This includes listening to soft music, receiving gentle hand massages, or engaging in simple, enjoyable hobbies. For individuals who fidget, providing worry beads or a box of meaningful items can occupy their hands.
- Addressing Unmet Needs: Always check for underlying physical issues. Pain, hunger, thirst, constipation, and infections can all manifest as restlessness or agitation. Since the person may not be able to articulate their discomfort, a thorough medical assessment is crucial.
Pharmacological Interventions for Agitation
When non-drug approaches are not effective or the behavior poses a significant risk of harm, a doctor may consider medication. It is crucial to have an open discussion about the potential risks and benefits. Only one medication is currently FDA-approved for agitation related to Alzheimer's dementia.
FDA-Approved Medication: Brexpiprazole (Rexulti)
In May 2023, the FDA approved brexpiprazole specifically for the treatment of agitation associated with Alzheimer's dementia.
- Mechanism: Brexpiprazole is an atypical antipsychotic that works by targeting serotonin and dopamine pathways in the brain.
- Effectiveness: Clinical trials showed significant improvement in caregiver-reported agitation symptoms.
- Boxed Warning: Like other atypical antipsychotics, brexpiprazole carries a boxed warning indicating an increased risk of death for older people with dementia-related psychosis.
Off-Label Use of Antipsychotics
Other atypical antipsychotics are often used off-label for agitation, meaning they are prescribed for a purpose other than their FDA-approved indication. These include risperidone, olanzapine, and quetiapine.
- Risks: These medications also carry the same serious black box warning about increased mortality risk. Other side effects can include sedation, cognitive worsening, and an increased risk of stroke, blood clots, heart failure, and falls.
- Use: When prescribed, it is typically for short-term use at the lowest possible dose, under constant medical supervision.
Off-Label Use of Antidepressants
For individuals whose agitation may be linked to underlying mood issues, certain antidepressants may be considered.
- SSRIs: Selective serotonin reuptake inhibitors (SSRIs) like citalopram or sertraline are sometimes used off-label. Some studies suggest they can help with agitation, but evidence is mixed and potential side effects exist. Some studies indicate that higher doses may be linked to a faster cognitive decline.
- Trazodone: This antidepressant may also be prescribed, with some evidence suggesting it helps with specific aggressive behaviors.
Other Medications
- Memantine: An anti-dementia drug for moderate-to-severe AD, memantine can sometimes help reduce behavioral disturbances like agitation. However, there are also reports of it paradoxically increasing agitation in some individuals.
- Dextromethorphan/Quinidine (Nuedexta): This combination drug may be effective at reducing agitation in some dementia patients, but more research is needed.
Comparing Medication Classes
This table provides a high-level comparison of the types of medication used for dementia-related restlessness.
Medication Class | Example Drugs | FDA Status for Agitation | Common Risks & Considerations |
---|---|---|---|
Atypical Antipsychotics | Brexpiprazole (Rexulti), Risperidone (Risperdal), Olanzapine (Zyprexa) | Brexpiprazole: FDA-approved for AD-agitation. Others: Off-label. |
Boxed Warning: Increased mortality in elderly with dementia-related psychosis. Stroke, sedation, falls, cognitive decline. |
Antidepressants (SSRIs) | Citalopram (Celexa), Sertraline (Zoloft) | Off-label use. | Mixed evidence for efficacy. Potential for side effects like increased risk of falls, sleep disturbances, cognitive decline. |
NMDA Receptor Antagonist | Memantine | Approved for moderate-to-severe AD; sometimes helps with behavioral symptoms. | Can paradoxically cause agitation in some individuals. Common side effects include headache and dizziness. |
The Importance of a Holistic Approach
The decision to use medication is never taken lightly. Due to the significant risks associated with many pharmacological options, especially for older adults, it is a last resort. Healthcare professionals emphasize a holistic, individualized approach that begins with understanding the person's history, personality, and current needs.
Working closely with a physician and a geriatric specialist is essential to develop a comprehensive care plan. The plan should integrate non-drug strategies first, while using medication judiciously if necessary, for the shortest possible duration, and with careful monitoring for adverse effects. Continued reassessment is vital to balance the potential benefits against the serious risks. Organizations like the Alzheimer's Association offer valuable resources for caregivers and families navigating this difficult journey.
Conclusion: A Path of Caution and Compassion
When dealing with restlessness in dementia patients, the path to management should always begin with a foundation of compassionate, person-centered non-pharmacological care. This involves thoughtful environmental adjustments, consistent routines, and empathetic communication. When medication becomes necessary, brexpiprazole is the only FDA-approved option for agitation associated with Alzheimer's. Other options, like off-label antipsychotics, antidepressants, and anti-dementia drugs, must be used with extreme caution and regular medical review due to serious safety risks, including a black box warning on antipsychotics regarding increased mortality. The best outcomes are achieved through a collaborative effort between caregivers, family, and medical professionals, with the ultimate goal of improving the individual's comfort and quality of life.
