They assembled a team of about a dozen others to assist them.<\/p>\n<p>\u201cThe Old Order Amish of Lancaster County have a lower incidence of mental illness than the general population, but a much higher incidence of bipolar disorder, \u201c said Hostetter.<\/p>\n<p>Bipolar disorder, also called manic depression, often leads to suicide. \u201cIt\u2019s in the blood,\u201d said an Amish grandmother\u2014or <em>siss im blut<\/em>, in Pennsylvania German\u2014when Egeland began her research.<\/p>\n<p>Bipolar disorder is characterized by episodes of mania or depression that typically recur and often become more frequent and severe during a lifetime. It\u2019s estimated that about 1 percent of the U.S. population has a major mood disorder.<\/p>\n<p>Over the years, scientists discovered an association between mood disorders and two known genetic markers. In other words, people suffering from bipolar disorder have inherited it from their parents.<\/p>\n<p>Hostetter and Egeland found that Old Order Amish families are ideal subjects for genetic studies for a number of reasons:<\/p>\n<ul>\n<li>They descend from a limited number of pioneer couples who came to America in the 18<sup>th<\/sup> century.<\/li>\n<li>There is little marriage to outsiders or other forms of in-migration, causing the Old Order Amish of Lancaster to form a closed gene pool<\/li>\n<li>They have large families and keep extensive genealogical records.<\/li>\n<li>They prohibit the use and abuse of alcohol and drugs, which often mask the symptoms of bipolar disorder.<\/li>\n<\/ul>\n<p>\u201cWe have a total pedigree of the Old Order Amish community in a computer from the original 32 adults who came in the 1760s until in the 1970s,\u201d said Hostetter, \u201cso we can determine what percentage of genetic endowment any two people share.\u201d<\/p>\n<p>The research team focuses on the original \u201cpedigrees,\u201d or cohort. About 65 percent of the families are named Stoltzfus. Other names are King, Zook, Lapp, Beiler, Petersheim, Blank, Fisher, Miller, Glick, Esch and Smoker.<\/p>\n<p>Hostetter grew up in Lancaster County in a Mennonite family and knew some Amish families with bipolar disorder. His grandfather, who was longtime moderator of <a href=\"http:\/\/www.lancasterconference.org\/\">Lancaster Mennonite Conference<\/a>, often consulted with Amish ministers. Hostetter\u2019s father was a farmer and tobacco broker and also had much interaction with the Amish.<\/p>\n<p>\u201cMy best friend, an Amish boy, in elementary school had bipolar disorder, as did his mother and grandmother,\u201d said Hostetter. \u201cHe committed suicide at age 18 and his sister committed suicide in the 1990s.\u201d<\/p>\n<p>Hostetter was a <a href=\"http:\/\/www.emu.edu\/pphs\/pre-med\/\">pre-med major<\/a> at Eastern Mennonite University for two years in the late 1940s. He earned his bachelor\u2019s degree from Goshen College in 1953. He graduated from Jefferson Medical College in Philadelphia and trained in psychiatry at Norristown State Hospital.<\/p>\n<p>He joined a private practice in his home area and later formed a group practice in Hershey, where he met Egeland, who was on the faculty of <a href=\"http:\/\/www.pennstatehershey.org\/web\/guest\/home\">Hershey Medical Center<\/a>. \u201cWe first spoke about using the Amish population in Lancaster County to solve the medical puzzle about inheritance of bipolar disorder in 1970,\u201d he said.<\/p>\n<p>Egeland and Hostetter both joined the faculty of the University of Miami but worked out of what they called \u201cUniversity of Miami, North Office\u201d in Hershey.<\/p>\n<p>Nine years ago Hostetter retired from his psychiatry practice at age 74 and moved with his wife to Charlottesville, Va. He returns to Pennsylvania about five times a year, though, to pursue his research. In December 2012 he joined Egeland there.<\/p>\n<p>\u201cWe worked on \u2018coding\u2019 cases to detect particular characteristics of each of their manifestations of illness,\u201d he said. \u201cWe have very detailed medical histories and DNA samples on over 100 bipolar patients.\u201d<\/p>\n<p>\u201cAt this point,\u201d Hostetter continued, \u201cwe are on the verge of whole genome sequencing for 80 subjects, still attempting to locate all the specific genes involved.\u201d<\/p>\n<p>Hostetter noted that bipolar disorder is treatable and that persons with the illness can lead normal lives. \u201cHowever, untreated or inadequately treated, there is still a 15 percent suicide rate, to say nothing of the suffering and turmoil these people have and put their families through,\u201d he said.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The link between genetics and mental illness continues to engage Abram Hostetter, a psychiatrist who is in his fourth decade of world-recognized research into why Old Order Amish are more <a href=\"https:\/\/emu.edu\/now\/news\/2012\/alumnus-remains-leading-researcher-into-bipolar-disorder\/\" target=\"_self\" class=\"more-link\">... read more <span class=\"screen-reader-text\">about Alumnus Remains Leading Researcher Into Bipolar Disorder<\/span><\/a><\/p>","protected":false},"author":112,"featured_media":15309,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[266,12579],"tags":[14687,8381,17393],"feature":[],"class_list":["post-15295","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-alumni","category-pre-professional-health","tag-abram-hostetter","tag-lancaster","tag-old-order"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.6 -
