At first, Dorothy Sorlie thought she was just getting old, though not as gracefully as she'd hoped. Retired from teaching English at a local college, Sorlie, then 74, began losing interest in things she'd enjoyed, including reading and cooking. She couldn't concentrate. Her handwriting changed. The symptoms occurred so gradually that initially she wasn't aware anything was happening.
Things kept getting worse. She started worrying that she might be developing early dementia (痴呆). The physical symptoms progressed too. Most worrisome, she began having trouble walking and started falling. Through it all, her doctors struggled to explain what was happening.
She and her husband, Jim Urness, were desperate for answers; It would take years before they got them. The doctors' diagnoses (诊断), all incorrect, could account for one or two of Sorlie's symptoms but not all of them, and none of the treatments seemed to help.
The couple traveled across the country looking for someone who could tell them what was wrong. However, one possible explanation for her symptoms after another proved incorrect. At last, Sorlie's primary care doctor, Kevin Wergeland found the disease responsible for all her symptoms was a little-known condition called normal pressure hydrocephalus (NPH). Although her condition was detected at an advanced state, it was treatable.
In fact, NPH is sometimes referred to as "treatable dementia". It is an insidious (潜伏的) and mysterious disorder that can copy many more common problems including Alzheimer's and Parkinson's. An estimated 700000 people in the United States have NPH, although ifs believed that fewer than 20 percent of them are correctly diagnosed.
Sorlie is now free of NPH symptoms, and taking advantage of her good health and using her dramatic recovery to inform others about NPH. She gives presentations to local senior centers as a volunteer. "If this awareness can help one person avoid what my husband and I endured, " Sorlie says, "then my efforts are worth it. "
