How we perceive or “see” something depends on how much we know about our own body and how it moves, and how well we take in information from our senses (what we see, hear, and feel). It also depends on how well we can compare new sensory information to information stored in our memory from past experiences. We can then use the combined information to make decisions about how to respond to new situations. This processed information builds over a lifetime. It lets us do the complicated tasks we do every day, like getting dressed, cooking, driving a car, or reading.
Damage to the areas of the brain that help us to understand our body and how it moves, as well as what we see, hear, or feel affects perception. Damage to the area of the brain involved in memory, thinking, and reasoning can affect how well sensory information is collected and stored. The damage can also affect how information is used to make decisions in new situations. Any of these changes can affect how well a person is able to do everyday tasks.
The following are some of the common perceptual problems that happen after a brain injury, how they affect everyday activities, and some ways of helping people with these problems.
Please talk to your healthcare provider, such as a physiotherapist or occupational therapist, for tips on how to help with perception problems.
