What is Apraxia?
Apraxia is a neurological condition that can be incredibly frustrating not only for individuals with dementia but also for their caregivers. Despite not being widely discussed, up to 52% of people with dementia experience apraxia at some point. It occurs when the brain’s messages don’t reach the body correctly, despite the physical ability to perform the action being intact. This disconnect can make everyday activities extraordinarily challenging. Can you imagine knowing how to do something but finding your body simply won’t cooperate?
Types of Apraxia in Dementia
Apraxia can be classified into several forms, depending on how it affects motor functions and the specific challenges it presents. Here are some of the main types of apraxia:
- Ideomotor Apraxia: Difficulty coordinating muscle movements needed to perform tasks, even though the task itself is understood.
- Ideational Apraxia: Difficulty sequencing the steps involved in complex tasks, leading to errors in the order of operations.
- Constructional Apraxia: Difficulty in organizing or assembling parts into a whole, often seen in tasks like drawing or assembling objects.
- Orofacial or Buccofacial Apraxia: Difficulty in carrying out movements of the face on demand, such as licking lips, whistling, or winking.
- Limb-Kinetic Apraxia: Difficulty with fine motor movements of a limb, such as using tools or manipulating small objects.
- Apraxia of Speech: Difficulty in planning and sequencing the movements necessary for speech, affecting the ability to form words correctly.
- Oculomotor Apraxia: Difficulty in controlling eye movements, particularly in making quick eye shifts.
Today, let's focus on the two most common types: ideomotor and ideational apraxia.
Ideomotor Apraxia: This type is prevalent in dementia patients who find it challenging to execute motor tasks, which can be deeply frustrating both for them and their caregivers. Ideomotor apraxia often manifests in everyday activities that require intentional movements or gestures. Patients may understand what is asked of them and even desire to complete the task, yet they find themselves unable to coordinate their muscles to do so. For instance, they may recognize the gesture for waving goodbye, know when it’s appropriate, and want to wave, but their hand simply doesn’t move as intended.
Real-life scenarios provide a clearer picture of how ideomotor apraxia plays out. Consider the action of unlocking a door with a key—an action that involves fine motor skills and a sequence of movements. A person with ideomotor apraxia might hold the key, approach the door, and then stand perplexed, unable to remember how to insert the key into the lock or turn it. Similarly, dressing becomes a daunting task rather than a routine part of getting ready. A patient might pick up a jacket, hold it up, and turn it around in their hands, visibly confused about how to proceed with putting it on.
These difficulties stem from the disconnect between the brain’s intention and the body’s execution. The brain sends the signal to perform an action, but somewhere along the line, the signal gets disrupted, and the intended movement doesn’t occur. This can be exasperating for patients who, in a sense, can still remember the action but find their bodies unresponsive. It’s not just forgetting how to perform the task; it’s more about the brain’s inability to communicate effectively with the muscles required to execute the task. This breakdown in communication is what makes ideomotor apraxia particularly perplexing and distressing, as the brain seems to forget how to do things it has orchestrated thousands of times before.
Ideational Apraxia: This form of apraxia presents a unique challenge, as it involves a breakdown in the sequencing of tasks. Individuals with ideational apraxia retain the knowledge of the tasks they need to perform but face significant difficulties in planning and executing these tasks in the correct order. Their cognitive processing errors manifest in everyday situations, often leading to actions that seem illogical to onlookers but make sense to them in the moment due to their disrupted sequencing abilities.
For example, when attempting to dress, a person with ideational apraxia might attempt to put shoes on before socks. In their mind, the goal is to complete the task of dressing, but the steps to reach that goal are muddled. Similarly, in the kitchen, making a sandwich—a task that requires a series of steps performed in a specific sequence—becomes a complex challenge. They might place two slices of bread together without any fillings or spread the peanut butter and jelly directly on the plate instead of on the bread. These actions are not merely mistakes; they are indicative of the struggle to recall and execute the sequence of steps involved in a task.
This type of apraxia goes beyond simple forgetfulness; it’s like the brain’s playbook has indeed been jumbled. The usual sequences that guide daily activities are disrupted, leading to frustration and confusion. Patients often realize that something is wrong but can’t pinpoint what it is or how to correct it. This can lead to feelings of helplessness and dependence, as even routine activities require significantly more effort and external guidance.
Ideational apraxia thus affects more than just physical actions—it impacts a person’s ability to live independently and perform tasks that are crucial for daily living. For caregivers and loved ones, understanding this condition is vital for providing the appropriate support and adapting care practices to accommodate the unique challenges posed by this disorder. Recognizing the need for structured guidance and clear, step-by-step instructions can help mitigate some of the daily frustrations experienced by individuals with ideational apraxia.
Coping Strategies for Managing Apraxia
Managing apraxia requires patience, understanding, and some clever strategizing. Here are a few tips to help your loved one navigate their daily challenges:
- Simplify Instructions: Break tasks down into simple, manageable steps. Instead of saying, “Get ready for lunch,” specify, “Let’s put on your jacket because it’s cold outside.” This helps in reducing the cognitive load required to interpret the task.
- Visual Cues: Use visual aids to guide the patient through tasks. This can be particularly helpful for those with ideational apraxia, who struggle with sequencing.
- Routine Reinforcement: Establishing a routine can help reinforce the sequence of activities, making it easier for the patient to remember and perform tasks with less confusion.
Apraxia often remains undiagnosed because its symptoms can be mistaken for general dementia progression. Understanding that apraxia is a distinct condition is crucial for effective management. It’s not just about the decline in cognitive function; it’s about finding ways to bridge the communication gap between the brain and the body. By identifying and addressing apraxia, we can tailor our care strategies to be more effective and compassionate.

Thank you for these articles. They are incredibly helpful in my understanding what may potentially be going on with my dad. Problem is he’s always acted helpless as long as I’ve known him and now I can’t tell if he’s got a real problem.
