What is a characteristic of an ACA stroke?

A characteristic of an anterior cerebral artery (ACA) stroke includes abulia and incontinence.

In a stroke affecting the ACA, the areas of the brain that control the lower limbs and some aspects of executive function may be impacted. Abulia refers to a lack of will or initiative, which can be seen in individuals with ACA strokes because of the involvement of the frontal lobe. Incontinence is also commonly observed due to the involvement of areas responsible for bladder control. Therefore, recognizing these symptoms is crucial for identifying an ACA stroke and understanding the functional impairments that may arise following such an event.

Other symptoms associated with ACA strokes may also include weakness in the contralateral leg more than the arm, but these specific symptoms highlight the behavioral and cognitive aspects related to the frontal lobe function affected in ACA strokes.
