To bolster public support for ratification, Wilson barnstormed the Western states, but he returned to the White House in late September due to health problems. On October 2, 1919, Wilson suffered a serious stroke, leaving him paralyzed on his left side, and with only partial vision in the right eye. He was confined to bed for weeks and sequestered from everyone except his wife and his physician, Dr. Cary Grayson. Dr. Bert E. Park, a neurosurgeon who examined Wilson's medical records after his death, writes that Wilson's illness affected his personality in various ways, making him prone to "disorders of emotion, impaired impulse control, and defective judgment." Anxious to help the president recover, Tumulty, Grayson, and the First Lady determined what documents the president read and who was allowed to communicate with him. For her influence in the administration, some have described Edith Wilson as "the first female President of the United States." In mid-November 1919, Lodge and his Republicans formed a coalition with the pro-treaty Democrats to pass a treaty with reservations, but the seriously indisposed Wilson rejected this compromise and enough Democrats followed his lead to defeat ratification.
