A new study indicates that certain types of games may help reduce the risk of Alzheimer's disease.

ABC News reports that researchers from the University of California-Berkeley determined this after interviewing 65 healthy people about their game-playing habits throughout their lives. These individuals also had their brains scanned to see if a high number of beta-amyloids were detected, a brain protein that is a hallmark of Alzheimer's disease.

Based on the images and responses, the researchers found that individuals who played games that involved thought - such as crossword puzzles, Sudoku or strategy-based computer games like Angry Birds or Tetris - had a lower chance of developing Alzheimer's disease, as they had fewer amounts of the brain protein.

However, Susan Landau, the study's lead author, told ABC News that just about any game that stimulates brain activity may be helpful.

"There was no emphasis on what games were played, but just at what age and how often people were participating in brain stimulating activities, including reading, writing, and games," said Landau.
