Although the rarer causes of dementia pose a challenge for even an experienced practitioner, most patients present with typical symptoms that should not be difficult to diagnose. A typical patient with Alzheimer's disease will forget recent events, such as what they did yesterday, often called "short term memory loss." But as the disease progresses, longer term memories, such as their year of high school graduation, or the age they were when they married, will be lost. Affected persons may forget to pay bills; social graces may be lost as well. Demented patients' judgment is often affected, making them susceptible to scams and poor financial decisions. Unfortunately, almost always patients lack insight into their deficits and do not complain of memory loss. This can delay diagnosis, as relatives may be slow to recognize their problems.
