Brain atrophy changes are quite severe, as brain atrophy is a change observable via imaging. If imaging techniques such as CT scans or MRI already reveal these changes, the morphological alterations are significant. Thus, there is a notable impact on limb movement. Post brain atrophy changes manifest as vascular dementia, cognitive impairments, and limb activities, particularly evident weakness in both lower limbs, as well as loss of bladder and bowel control, personality changes, cognitive changes, and emotional disturbances. These symptoms are quite severe.
