What is a common feature of anterior cerebral artery infarction?

Infarction of the anterior cerebral artery (ACA) often leads to specific clinical features due to its role in supplying blood to the medial portions of the frontal and parietal lobes. A key characteristic of ACA infarction is the impact on motor control and function, particularly affecting the lower extremities.

Loss of bladder control can occur in patients with anterior cerebral artery infarction because damage to this area can disrupt the neural pathways involved in bladder management. The frontal cortex, particularly the medial frontal lobe supplied by the ACA, plays a role in controlling voluntary bladder function. Therefore, significant damage in this region can lead to issues with involuntary bladder control.

Meanwhile, the specific motor deficits typically associated with ACA infarctions include contralateral hemiplegia affecting the lower extremity more than the upper extremity. This pattern arises because the ACA supplies regions of the motor cortex that primarily control the legs, leading to weakness or paralysis more pronounced in the legs.

Therefore, while the loss of bladder control is indeed a common feature related to anterior cerebral artery infarction, the other manifestations, such as sparing of the lower extremity, are not consistent with the expected clinical picture of this type of vascular event.
