Seniors, Pessimism and NPY
Scientists at the University of Michigan have performed a study to determine what causes seniors to be pessimistic. The outcome of the study has revealed that the molecule known as NPY is actually responsible for optimism and pessimism. When the brain has high levels of the molecule, seniors will be optimistic. However, low levels not only induce pessimism, but can also be linked to depression.
1. The molecule is called neuropeptide Y, also referred to as NPY. Low levels of this may be the reason many seniors have difficulty coping with stress.
2. The study revealed that low levels of NPY resulted in an increased activity in the prefrontal cortex of the brain. This is what processes emotion. The increase was seen when participants in the study were exposed to negative words.
3. People with low levels of NPY are more apt to have a negative outlook on things and experience more negative feelings.
4. The reaction due to the levels of the molecule may be directly related to depression. Studies are being conducted to determine if using this molecule could be a treatment for severe depression.
5. At this time, the study does not show how pessimists can become more positive.
