Free Visual Perception Packet Visual perception is made up of several areas that are crucial to development, learning, and functioning. Because of this, patients are also more likely to experience a debilitating loss of independence in ADLs (Jehkonen and Colleagues, 2006), which makes treating this aspect of the patients condition post-injury even more important. WebVisual Inattention/Neglect (Strategies to Help Individuals) Stroke or brain injury can affect a persons ability to see or attend to one-half of his visual field.
