A common symptom indicating involvement of the right ACA may include?

• A. right arm paralysis
• B. left leg weakness
• C. speech deficits
• D. right visual field loss

Answer: (B)

Involvement of the right anterior cerebral artery (ACA) typically affects the motor and sensory functions of the lower extremities due to its vascular supply to the medial portions of the frontal and parietal lobes. This area of the brain is associated with controlling the movement and sensation of the contralateral leg. Therefore, a common symptom of right ACA involvement would manifest as weakness or paralysis of the left leg, since the motor control is contralateral to the side of the brain affected. The other options relate to different areas of the brain or conditions. Right arm paralysis would generally be linked to the left side of the brain, which controls the right arm, while speech deficits are commonly associated with the left hemisphere, particularly in regions such as Broca’s area or Wernicke’s area. Right visual field loss typically indicates involvement of the left hemisphere's processing areas for visual information. Thus, left leg weakness is the most characteristic symptom associated with a right ACA stroke due to its specific control over the lower limbs.
