Cognition, or information processing, is often affected by mental illness. My daughter had a tough time being able to make choices and to follow simple sequences of tasks. Her thinking and perception were impaired, and it took time before she regained these skills. Cognitive difficulties were not immediately apparent to me and it was frustrating until I learned that issues like this were common with mental illness. When I recognized that she was not necessarily being lazy or making unwise decisions, that she just simply could not process the information correctly, it was a lot easier for me to accept why she was not helping out around the house.
