540 5-2 Discussion: Memory Impairment Memory loss or impairment can be difficult to deal with because it affects many aspects of life. Many factors and conditions can lead to memory loss. Conduct a little research, and report on two different types of memory loss. Compare and contrast (Parkinson's disease, and dementia) changes in the brain and memory that occur with each type of memory loss. After discussing specific types of memory loss, provide a few suggestions for improving memory based on what you learned about memory systems in this week's readings.
