Damage to the frontal lobes and frontolimbic tracts can result in disinhibition, impulsivity, and mood changes due to impaired regulation by the limbic system. Irritability, mood swings, loss of control, and impulsiveness are examples of such clinical manifestations.

B, C, and D are incorrect because deficits in attention and coherence of thought, loss of motor movement and coordination on the side opposite the damage, and change in level of consciousness and pupillary reaction are more characteristic of damage to other areas of the brain, such as the parietal or occipital lobes, basal ganglia or brainstem, or the reticular activating system, respectively.
