Understanding Agitation in Alzheimer’s Disease

Alzheimer’s disease is a devastating condition affecting millions, not only through memory loss but similarly through a range of behavioral changes. Among these, agitation is a frequently overlooked symptom that can significantly impact both the individual with Alzheimer’s and their caregivers. Currently, over 7 million Americans aged 65 and older are living with Alzheimer’s disease ¹, and understanding agitation is crucial for effective care.

What is Agitation in Alzheimer’s Disease?

Agitation in Alzheimer’s isn’t simply feeling upset. It’s a behavioral syndrome characterized by increased motor activity, restlessness, emotional distress, and sometimes aggression. It can manifest in various ways, including:

• Pacing
• Attempts to leave home
• Angry outbursts
• Leverage of profanity
• Physical aggression, such as hitting
• Mood swings
• Throwing objects

It’s vital to recognize that agitation stems from brain changes caused by the disease, not from poor caregiving ². The brain damage inherent in Alzheimer’s predisposes individuals to agitation, regardless of the love and care they receive.

Why Caregivers Often Misinterpret Agitation

Caregivers often mistakenly blame themselves for a loved one’s agitation, believing it’s a result of burnout, changes in routine, or a lack of patience. Though, research indicates that agitation is a common symptom, occurring in 56% of those in the early stages and 68% in the moderate to severe stages of the disease ². There’s often a stigma associated with this symptom, leading caregivers to feel they are doing something wrong when, in reality, they are responding to a neurological issue.

The Neurological Basis of Agitation

The same brain damage that causes memory loss in Alzheimer’s also affects areas responsible for regulating attention, focus, fear, and anger ⁴. This damage, combined with a diminished ability to communicate needs, creates a perfect storm for behavioral issues like agitation. In fact, approximately 90% of people with Alzheimer’s will experience some form of neuropsychiatric symptom throughout the course of their illness ⁴.

Early Warning Signs

While predicting outbursts can be challenging, being aware of potential red flags and triggers is essential. Early signs of agitation can include restlessness and increased anxiety. Recognizing these subtle changes can allow caregivers to proactively address potential triggers and implement strategies to de-escalate the situation.

The Importance of Recognizing Agitation as a Symptom

Understanding that agitation is a symptom of Alzheimer’s, not a reflection of caregiving quality, is paramount. This understanding can alleviate caregiver guilt and encourage them to seek appropriate support and strategies for managing this challenging behavior.
