Personality Has Significant Impact , on Brain Health, , New Study Finds.<br />The study was conducted by researchers at the University of Victoria and published in the 'Journal of Personality and Social Psychology.'.<br />It found a connection between traits of personality and the development of mild impairment of brain function.<br />Personality traits reflect relatively enduring patterns of thinking and behaving, , Dr. Tomiko Yoneda, Lead Author, via CNN.<br />... which may cumulatively affect engagement in healthy and unhealthy behaviors and thought patterns across the lifespan, Dr. Tomiko Yoneda, Lead Author, via CNN.<br />The accumulation of lifelong experiences may then contribute to susceptibility of particular diseases or disorders, Dr. Tomiko Yoneda, Lead Author, via CNN.<br />... such as mild cognitive impairment, or contribute to individual differences in the ability to withstand age-related neurological changes, Dr. Tomiko Yoneda, Lead Author, via CNN.<br />Medical professionals reacted to the study, saying that it remains unclear whether personality leads to impaired cognition, .<br />... or if a genetic predisposition to cognitive impairment may be expressed through personality.<br />Specific traits may increase risk due to a lifetime of behaviors that predispose a person to developing cognitive decline or Alzheimer's disease, , Dr. Richard Isaacson, Alzheimer's Prevention Clinic, via CNN.<br />... or there could be more of a direct biological role related to early disease pathology, Dr. Richard Isaacson, Alzheimer's Prevention Clinic, via CNN.<br />Health professionals point to neurotic tendencies as an example of uncertainty over which comes first.<br />Neuroticism is specifically one trait that comes to mind, and past meta-analyses have also show this. Rumination and worry is linked to smaller brain volumes, Dr. Richard Isaacson, Alzheimer's Prevention Clinic, via CNN.<br />It's unclear if the stress/neuroinflammation pathway drives this. A biomarker doesn't really exist for this so it's hard to prove, Dr. Richard Isaacson, Alzheimer's Prevention Clinic, via CNN.<br />However, this study is the latest of recent research to find a clear link between cognitive health and personality
