What is Dementia Agitation?
Dementia agitation is a set of behavior that is characterized by restlessness, irritability, trouble sleeping, and emotional distress in people with dementia. The person may show wandering, pacing, verbal, and physical aggression, or resistance to care.
It is a common problem in people with various forms of dementia including Alzheimer’s disease, vascular disease, and Lewy body dementia. According to a study, 90% of people with dementia eventually develop agitation and other behavioral symptoms.(1)
Dementia agitation can be managed by knowing about the underlying cause and treating it.(2) It can also be managed with a calm environment, emotional support and reassurance, and using medications and interventions as appropriate. The treatment can also be tailored according to individual needs under the guidance of a healthcare professional.

Dementia agitation affects both the individual as well as their caregivers.
It can increase the level of stress, anxiety, and confusion in the individual. They might start harming themselves or others physically. Their ability to participate in daily activities would gradually get affected, they may interact less with others and this in turn may affect their quality of life.
The caregivers can have a hard time managing the agitation in the individuals, which may increase their stress and burden. The caregivers may experience emotional distress when they see their loved one suffering. They may have feelings of guilt and helplessness. Also, dementia agitation may impact the ability of caregivers to provide effective care.

Dementia agitation can be challenging for an individual as well as their caregivers. It may also contribute to cognitive decline. Persistent agitation in dementia can be a reason for cognitive decline as well as a decline in the quality of life.(3)
It is important to seek help and support from a healthcare professional to help manage the symptoms of dementia and improve the overall quality of life.
Conventional Treatment of Dementia Agitation
The conventional treatments involved in dementia agitation include both pharmacological and non-pharmacological interventions.
The non-pharmacological interventions include:
- Creating a calm environment by adjusting the stressors including noise, clutter, and bright lights.
- Engaging in calming activities including music art and gentle exercises.
- Reducing over-stimulation by limiting exposure to external stimuli such as noise and chaotic environment.
- Providing sensory stimulation such as blankets and textured objects to help reduce agitation.
The pharmacological intervention includes medications to manage dementia. These include:
- Antipsychotic medications, which are used in the treatment of severe agitation in patients with dementia.(5) But, these medications have side effects linked with them and hence should be used with caution.(6) A person taking antipsychotics should be closely monitored by a healthcare professional and the caregiver.
- Antidepressants may be used for anxiety and depression that may contribute to agitation.(4) These medications can increase the risk of heart issues in older people. Therefore, it is important to take them under a doctor’s guidance.
- Anxiolytic medications are also used for the treatment of anxiety to reduce agitation in some people.
- Always the treatment should start with non-pharmacological options. If they are ineffective, pharmacological options should be considered. The medications have benefits as well as side effects.
Benefits of medications used for dementia agitation include:
- Medication can effectively reduce agitation and bring down its frequency.
- It can sometimes reduce the risk of agitation and keep the patient from having aggressive and dangerous behavior.
- Agitation can sometimes disrupt sleep patterns. Medications can be helpful in improving sleep.

- The medication may have its own side effects such as sedation, confusion, and movement issues, especially in older adults.
- There is an increased risk of mortality in people using antipsychotic medications.
- The medication may provide short-term relief but may be lacking in long-term effectiveness. People may also develop tolerance to the medication gradually and the dosage may be needed to be increased or a change in medication would be required.
- The medication’s cost may also be an issue for some people as they may find them to be too expensive.

- Due to a lack of standardization, there may be significant variability in the quality and effectiveness of these treatments.
- Some of these treatments can be expensive and may also not be covered by insurance.
- The effect of these treatments is slow. This can delay the treatment.
