The reductions in the physiological operations of the brain have an effect on the person's abilities to:
- pay attention to information,
- access procedural and long-term memories,
- retain information in working memory,
- learn and remember new information,
- talk,
- coordinate their gross, fine motor and bilateral movements,
- understand what they read,
- write or text a message, and
- comprehend what money is.
All these reductions reduce their capacity to manage their own affairs.
