STOCKHOLM -- Clinicians shy away from disclosing a diagnosis of mild cognitive impairment and its potential to convert to Alzheimer's disease.
They also differ in how they word the disclosure when they opt to share the diagnosis and prognosis with the patient and relatives. For their part, families may not want patients to know when they have been diagnosed with Alzheimer's disease, according to reports presented at the 12th Congress of the International Psychogeriatric Association.
"In dementia, disclosure is not common clinical practice"--only about 15% of professionals disclose the diagnosis to patients--"but there seems to be a trend toward more openness about the diagnosis," said Els Derksen, R.N., a researcher at the Alzheimer's center at St. Radboud University Medical Center, Nijmegen, the Netherlands. But in contrast to several studies of disclosing a diagnosis of dementia, no studies have been published about disclosing a diagnosis of mild cognitive impairment (MCI).
Ms. Derksen discussed the responses of physicians who completed an optional appendix to a questionnaire that was a part of the European DESCRIPA (Development of Screening Guidelines and Diagnostic Criteria for Predementia Alzheimer's Disease) multicenter study. The study included patients with suspected MCI.
In discussions with 101 patients with MCI or possible early dementia, physicians told 28% that they had MCI, 62% that they had abnormal memory or cognitive problems, 4% that they had worrisome symptoms or depression plus memory problems, 3% that they had normal memory problems or forgetfulness, 2% that they had amnestic symptoms, and 1% that they had mixed and vascular dementia.
Among 100 patients who received information about their prognosis, physicians told 4% nothing, 18% that the prognosis was unknown or uncertain, 20% that the condition probably would remain stable, 10% that it probably would progress, and 66% that follow-up would be indicated. (The percentages do not add to 100% because follow-up was included with other information for some patients.)
When physicians were asked to describe their use of the term Alzheimer's disease in their interactions with a total of 80 patients, they reported that they did not use the term at all in 23%. Physicians told 72% that they could possibly convert to Alzheimer's disease. They told 4% of the patients that they had Alzheimer's disease or predementia, and 1% that Alzheimer's was not present or detected.
In nearly all instances, the same information about diagnosis, prognosis, and specific use of the term Alzheimer's disease was given to patients' families. …
