Understanding the Root Causes of Agitation
Before considering any treatment, it is crucial to investigate the underlying triggers of agitation. Dementia-related behaviors are often a form of communication when a patient can no longer express their needs effectively. Identifying and addressing these issues is the first and most effective step toward calming a person with dementia.
Common causes of agitation
- Physical Discomfort: Unrecognized pain, hunger, thirst, constipation, or a full bladder can cause distress. Caregivers should look for non-verbal cues like grimacing or restlessness.
- Environmental Triggers: Excessive noise, glare, confusing clutter, or an unfamiliar environment can overwhelm a person with dementia. Changes to routine can also be highly unsettling.
- Overstimulation or Understimulation: Too much activity, noise, or people can be overwhelming, while boredom can lead to restlessness and agitation.
- Fear and Confusion: Delusions, paranoia, or difficulty with reasoning can cause fear. Symptoms like sundowning, where confusion worsens in the late afternoon, are a common source of agitation.
- Poor Sleep: Sleep disturbances and fatigue are known to increase late-day restlessness and irritability.
Non-Pharmacological Strategies to Calm Patients
Many dementia specialists and recent studies emphasize that non-drug interventions are safer and often more effective than medication for managing agitation. These strategies focus on person-centered care, tailoring the approach to the individual’s preferences, history, and needs.
Practical non-drug approaches
- Create a Consistent Routine: Predictable daily schedules for meals, bathing, and bedtime provide a sense of security and reduce confusion.
- Modify the Environment: Reduce noise and clutter to create a peaceful atmosphere. Use nightlights to prevent nighttime confusion and close blinds at dusk to minimize disorienting shadows.
- Use Sensory Therapies: Engaging the senses can be highly calming.
- Music Therapy: Playing familiar, gentle music can reduce agitation. Personalized playlists based on the person's past can be especially effective.
- Therapeutic Touch: A gentle hand massage or holding the person's hand can provide reassurance and comfort.
- Aromatherapy: Using calming scents like lavender has shown some benefit, though studies are mixed.
- Provide Engaging Activities: Meaningful activities can occupy and distract from agitated thoughts. Simple tasks like folding laundry, sorting objects, or gardening can be helpful.
- Validate and Reassure: When a patient expresses fear or distress, respond to the emotion rather than correcting the facts. Phrases like, “I can see you’re upset. I am here for you,” can be more effective than arguing.
Medications Used for Agitation
When non-pharmacological methods are insufficient, a physician may consider medication. It is critical to note that many of these drugs carry significant risks, and treatment should be closely monitored by a specialist, such as a geriatrician or psychiatrist.
Comparative Overview of Dementia Medications
| Medication Class | Primary Purpose in Dementia | Key Risks/Side Effects | Use Considerations |
|---|---|---|---|
| Atypical Antipsychotics (e.g., brexpiprazole, risperidone, quetiapine) | Addresses severe agitation, aggression, hallucinations, and delusions. Brexpiprazole (Rexulti) is the only FDA-approved atypical antipsychotic specifically for agitation associated with Alzheimer's. | Increased risk of stroke, death, sedation, falls, and extrapyramidal symptoms. | Should only be used for severe symptoms that pose a danger to the patient or others, and for the shortest possible duration. Use with extreme caution in patients with Lewy body dementia. |
| Antidepressants (SSRIs) (e.g., citalopram, sertraline, trazodone) | Manages agitation associated with anxiety, depression, or sleep problems. | Variable effectiveness for agitation alone. Some are associated with increased fall risk or heart problems, particularly at higher doses. | Often used for patients with co-existing depression or anxiety. Side effects are generally less severe than antipsychotics. |
| Anxiolytics (e.g., lorazepam, oxazepam) | Short-term management of acute anxiety or severe restlessness. | Can worsen confusion and increase risk of falls. There is a high risk of dependence and sedation. | Use is generally discouraged due to significant risks, but may be used at the lowest possible dose for very short periods. |
| Cholinesterase Inhibitors (e.g., donepezil, rivastigmine) | Primarily for cognitive symptoms, but may also slightly reduce agitation in some cases, particularly in specific dementias like Lewy body dementia. | Nausea, vomiting, diarrhea, and fatigue are common. | Not prescribed specifically for agitation, but can have a calming effect as a secondary benefit in some patients. |
Combining Approaches for Comprehensive Care
Effective dementia care almost always requires a multifaceted approach that combines non-drug strategies with careful medical management. A team of specialists, including neurologists, geriatricians, and occupational therapists, can help create a personalized care plan. Caregiver education is also vital to understanding and implementing these strategies effectively. By treating the person, not just the dementia, caregivers can enhance quality of life and reduce the need for powerful, high-risk medications. Finding what works best is a process of observation, flexibility, and patience.
Conclusion
While various medications are available for dementia-related agitation, such as atypical antipsychotics and antidepressants, the safest and most effective first-line approach involves prioritizing non-pharmacological interventions. Behavioral strategies—like creating a calm environment, maintaining routine, and using sensory therapies—address the root causes of distress without the serious risks associated with drugs. When medication is necessary, it must be used cautiously and under expert supervision to manage severe symptoms, always weighing the benefits against potential side effects. A comprehensive, person-centered approach provides the best chance for keeping a dementia patient calm and comfortable.
