Which brain region is most likely to experience cerebrovascular lesions that cause post-event depressive symptoms?

The temporal lobe is closely associated with emotional regulation and memory, and it is critical in the processing of auditory information and the integration of sensory input. Post-event depressive symptoms have been linked to cerebrovascular lesions in areas of the brain responsible for managing mood and emotions. The temporal lobe contains structures such as the hippocampus and amygdala, which play significant roles in emotional processing and memory. When cerebrovascular lesions occur in this region, they can disrupt the neural pathways associated with these functions, potentially leading to symptoms of depression following an event such as a stroke.

In contrast, the other regions listed may be less directly involved in emotional processing. The cerebellum primarily coordinates movement and balance, while the occipital lobe mainly processes visual information. The pons has functions related to respiration and sleep, but it is not as closely tied to mood regulation as the temporal lobe is. Thus, lesions in the temporal lobe can be particularly impactful in the development of depressive symptoms post-event.
