TRANSCORTICAL APRAXIA Meaning and
Definition
-
Transcortical apraxia is a neurological disorder characterized by a difficulty in executing purposeful and planned movements, typically caused by damage to specific parts of the brain. More specifically, it is characterized by impaired motor planning and execution, resulting in various forms of apraxia.
Apraxia refers to a loss or impairment of the ability to perform skilled movements, despite having the physical capability to do so. Transcortical apraxia is often due to lesions or abnormalities in the dominant hemisphere of the brain, particularly the parietal, frontal, or supplementary motor areas, although it can also be a result of damage to subcortical structures.
Individuals with transcortical apraxia may experience difficulty performing complex tasks that involve multiple steps, such as dressing, cooking, or using tools. They may exhibit unusual and awkward gestures, difficulty imitating movements, or have trouble coordinating their limbs to perform certain actions. However, their muscle strength and coordination for routine automatic movements may remain intact.
The term "transcortical" refers to the involvement of cortical areas neighboring the traditional motor cortex, such as the premotor and supplementary motor areas. These regions play crucial roles in initiating, planning, and sequencing movements. Hence, damage to these areas can disrupt the normal motor programming and execution processes, leading to transcortical apraxia.
In conclusion, transcortical apraxia is a neurological condition characterized by impaired motor planning and execution, resulting in difficulties performing purposeful and planned movements. Proper assessment, diagnosis, and rehabilitation strategies can help manage the symptoms and improve functional abilities for individuals affected by this disorder.

Etymology of TRANSCORTICAL APRAXIA
The term "transcortical apraxia" comes from combining the words "transcortical" and "apraxia".
1. Transcortical: "Trans" is a Latin prefix meaning "across" or "beyond", and "cortex" refers to the outer layer of the brain, which is responsible for higher cognitive functions. Therefore, "transcortical" refers to something that goes beyond or involves the cortex.
2. Apraxia: "A" is a prefix meaning "without" or "lack of", and "praxis" is a Greek word meaning "action" or "movement". Therefore, "apraxia" refers to a condition characterized by the inability to execute or perform voluntary movements, despite having intact muscle function.
