Primary care is the ideal setting to screen for mild cognitive impairment. Screening can be performed in under 10 minutes using brief cognitive assessment tools. When it comes to treatment, deprescribing is a priority, as many drug interactions contribute to cognitive disorders. Drugs also influence the value of nondrug therapies.
At the XXIX National Congress of General and Family Medicine of the Spanish Society for General and Family Physicians, Granada, Spain, Alberto Freire, MD, a family doctor and head of the society’s neurology group, presented a way to detect cognitive impairment in a few minutes during a primary care office visit. He also presented a stepwise algorithm for diagnosing and treating the condition, which is highly prevalent and underdiagnosed.
The specialist dismissed the idea that “memory problems are associated with age,” though it is true that in normal aging, “cognitive frailty develops, and some processes will move a little slower. But there won’t be significant functional impairment.” Mild cognitive impairment falls between normal aging and dementia.
“Primary care is essential for screening for mild cognitive impairment due to its high level of accessibility, proximity, and continuity, but most of all due to its longitudinal perspective, which differentiates it from other specialties,” said Dr. Freire. He pointed out that screening is not the same as diagnosis because screening merely indicates probability or well-founded suspicion that can then be confirmed in secondary care.
He also highlighted the need for assessment of cognitive function using brief cognitive tests, as well as the need for functional assessment of activities of daily living. Many cognitive function tests are available, some of which are patient oriented and some caregiver oriented.
“The patient initially comes to see us due to memory loss that he or she, or that some reliable reporter, has detected,” said Dr. Freire. He indicated that 18.5% of consultations for cognitive impairment are prompted by subjective perceptions of memory complaints, which represent the most common subtype of the condition: mild amnestic cognitive impairment.
Quick cognitive tests
Dr. Freire was in favor of picture-based tests, which he strongly recommended. “These are the most-studied tests in Spain for detecting neurocognitive impairment, and they eliminate the reading factor. They’re quick, they’re easy to use and interpret, and are well-accepted by patients. Also, they assess executive function (verbal fluency) and memory.” Dr. Freire stressed the importance of referencing categories when showing the pictures, as well as the fact that the test is available for free online.
He also questioned whether the Mini-Mental State Examination is dead because “there’s an abbreviated version that the author rejects, and the author’s permission is required to use it. It’s very appropriate for Alzheimer’s disease, but not for cognitive impairment.”
Another notable test is the episodic test (a test that avoids interfering with working memory). It has been validated for amnestic mild cognitive impairment and Alzheimer’s disease, but a reliable caregiver is required to verify patient responses.
For caregiver-oriented tests, Dr. Freire pointed to AD8, which, when paired with any brief cognitive test, significantly increases detection of cognitive impairment.
He also recommended a useful website for everyday consultations created by several scientific societies, including the Spanish Society of General and Family Physicians. The site includes the AD8 and Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) questionnaires that can be completed online. “It produces a score that indicates the likelihood that the patient has cognitive impairment, and it can be filled out by family members or caregivers to get the result during the consultation,” he said.
