What neurological disorder can cause 'falling towards the side of lesion' as a symptom?

The symptom of "falling towards the side of the lesion" is characteristic of a condition known as AICA syndrome, which is associated with a blockage of the anterior inferior cerebellar artery. This syndrome can lead to symptoms due to the involvement of the cerebellum and other brainstem structures. The cerebellum plays a vital role in coordinating balance and movement, and when one side is affected by a lesion, patients may exhibit difficulty maintaining balance and may tend to lean or fall toward the side of the lesion, as their proprioceptive and motor coordination is disrupted on that side.

In contrast, other syndromes like MCA syndrome, PCA syndrome, and Basilar syndrome present different symptoms and issues based on the regions of the brain they affect. MCA syndrome primarily influences motor and sensory functions associated with the lateral aspect of the brain, including weakness in the contralateral arm and face, along with other cognitive deficits. PCA syndrome primarily affects visual processing areas, leading to visual field deficits rather than balance issues. Basilar syndrome involves symptoms related to brainstem injury and can cause a range of neurological impairments, but does not typically lead to leaning or falling towards a specific side in the way that AICA syndrome does. Thus, the specific mechanism of
