Apraxia, although little known outside the medical field, affects thousands of people around the world. This neurological disorder prevents those who suffer from it from making voluntary movements directed towards a specific action, despite having sufficient strength and coordination. The most recent figures indicate that, in Spain, nearly 100,000 people suffer from apraxia. 10% of people who have suffered a stroke have some degree of apraxiaBut what exactly does it consist of? What types are there and how can they be rehabilitated? How does it affect daily life and what solutions does science offer?
Apraxia is a neurological disorder that affects the ability to perform directed movements, even when there are no problems with muscle strength or coordination. This article discusses the types of apraxia most common, the rehabilitation options available and how these interventions can improve daily life. In the words of a study published in The Lancet Neurology In 2023, apraxia "represents a failure in the connection between intention and execution, affecting areas of the brain responsible for motor planning."
For example, a person with apraxia may be unable to shake hands or use a toothbrush effectively, even if he or she knows how.
Causes: Brain damage and underlying factors
Brain injuries, such as those caused by stroke, head trauma or neurodegenerative diseases, are the most common causes of apraxia. This disorder not only limits physical movements, but also affects the ability to communicate in cases such as apraxia of speech.
The most common cause of apraxia is brain injury. These can be due to:
- cerebrovascular accidents (strokes): responsible for more than 50% of cases according to the Spanish Society of Neurology.
- Head injuries: especially common in young adults after accidents.
- Neurodegenerative diseases like Alzheimer's and multiple sclerosis.
- Brain tumors or infections such as encephalitis.
The impact depends on the brain region affected, mainly the frontal and parietal lobes, responsible for planning and executing movement.
Most common types of Apraxia
The diagnosis of apraxia includes a classification according to the affected areas. The main ones are described below: types of apraxia:
- Ideomotor Apraxia: Difficulty performing simple movements, such as waving or pointing at an object.
- Ideational Apraxia: Problems performing sequences of actions, such as preparing a sandwich.
- Constructional Apraxia: Difficulty assembling objects or drawing figures.
- Apraxia of Speech: Difficulty articulating words precisely.
- Orofacial Apraxia: Problems moving the muscles of the face voluntarily.
These types affect daily activities differently, and each requires a specific approach in management. rehabilitation.
Neuroplasticity: An opportunity for rehabilitation
La neuroplasticity is the brain's ability to reorganize itself by forming new neural connections. In the case of apraxia, this phenomenon is key to recovery. Recent studies have shown that the brain can reconfigure healthy areas to take over lost functions due to injuries.
For example, a report from the American Academy of Neurology of 2022 revealed that patients with apraxia undergoing repetitive and structured therapies showed an improvement in 35% of its functional capacity, thanks to the activation of alternative neural networks.
Impact of apraxia on daily life
Apraxia profoundly affects quality of life. According to data from the World Health Organization (WHO), more than 60% of people with moderate or severe apraxia need support to perform tasks such as dressing or cooking. For example, a patient with ideational apraxia may be unable to handle basic tools, which limits their autonomy at home.
Rehabilitation: Key to improving functionality
La rehabilitation of apraxia It is essential to improve quality of life and recover skills. There are several strategies that have proven to be effective:
- Occupational Therapy: Train specific motor skills to facilitate daily activities.
- Speech Therapy: Vital to address apraxia of speech, with exercises focused on muscle coordination.
- Physiotherapy: Helps improve body movements and coordination.
- Technology and Robotics: Devices such as Inrobics Rehab® They offer personalized interactive sessions that improve both motor and cognitive skills.
A recent study highlights that the incorporation of robotics can increase the effectiveness of therapies by up to 40%, offering new hope for those suffering from this disorder.
Conclusion: Apraxia, types and rehabilitation
Apraxia, in any of its forms, is a significant challenge, but with the right tools, it is possible to improve the quality of life. Understanding the types of apraxia and take advantage of the possibilities offered by the rehabilitation, including advanced technologies, is key to overcoming limitations and regaining independence.
