Definition, diagnosis, and treatment

Most of us who are older than 50 have experienced what we may jokingly call a “senior moment.” The name of a favorite movie is easy enough to recollect, but—what was the name of the actor who co-starred? Later the same day, that actor’s name pops up, virtually unbidden, at the front of the brain. Not to worry, says the Alzheimer’s Association, “Changes in cognition (e.g., thinking) are a natural part of aging.”

The human brain is at peak performance from its teen years into the 40s and 50s. After that, the Alzheimer’s Association notes cognitive abilities may diminish a bit. For many of us, these small changes don’t interfere with daily life and are undetected during formal cognitive testing. In other words, most of us likely will experience some changes in cognition as we age. As a result, we rely on lists a little more often, and we forget a name or date here and there.

But when cognitive changes become more troubling, it’s time to talk to a physician. Make that call if:

  • Simple decisions become hard to make
  • Appointments are missed due to forgetfulness
  • Recent conversations can’t be recalled
  • Visual perception changes

Definition and Risk Factors

Symptoms like those listed above may be caused by mild cognitive impairment, also known as MCI. This condition sits somewhere between infrequent forgetfulness and dementia on the cognition spectrum. The Mayo Clinic notes that MCI “causes a slight but noticeable and measurable decline in cognitive abilities, including memory and thinking skills.” According to the Mayo Clinic, about 15% to 20% of people 65 and older have MCI.

The most common risk factors associated with MCI are the same as for dementia, says the Mayo Clinic, and include “advancing age, family history of Alzheimer’s disease or other form of dementia, and conditions that raise the risk for cardiovascular disease.” The risk for MCI increases as a person ages, and it appears that men are more likely to have MCI than women. About 5% to 20% of those with MCI eventually develop dementia. Though in some cases, MCI can be an early stage of Alzheimer’s or dementia, this is not true for all.

Diagnosis

A physical exam by a specialist can yield an accurate diagnosis of MCI. The Mayo Clinic notes that an examination of this type will include:

  • Thorough medical history, including any family history of dementia
  • Assessment of independent function and performance of daily activities
  • Input from loved ones for their perspective
  • Assessment of mental status to evaluate memory, planning, judgment, ability to understand visual information
  • Neurological exam to assess nerves, reflexes, coordination, senses
  • Evaluation of mood to detect depression
  • Lab tests that may include blood work and brain imaging

When a specialist tests for MCI, he or she will also look for cognitive problems that may be caused by depression and side effects from medications. If a diagnosis is difficult to make, a specialist may recommend neuropsychological testing. It evaluates thinking skills, or further brain imaging or cerebrospinal fluid tests that can determine whether an individual has MCI due to Alzheimer’s disease.

There are two types of MCI; symptoms help determine which type an individual has.

  • Amnesic MCI most often affects memory. Someone with this form of cognitive impairment may forget things that were once easily remembered: a recent conversation or event or an upcoming appointment.
  • Nonamnesic MCI most often affects thinking skills unrelated to memory: difficulty making decisions, for example, or an inability to determine how long a task might take to complete (or the steps involved to reach completion). Changes in visual perception can also be an indicator of nonamnesic MCI.

Treatment

Currently, there are no drugs approved by the Food and Drug Administration for the treatment of MCI.

However, if depression or medication is causing MCI-like symptoms, the condition can be treated with a change in medication or evaluation and treatment of depression. The Alzheimer’s Association notes that aerobic exercise, mental activity, social engagement, and management of cardiovascular risk factors (including blood pressure and cholesterol) may help reduce the risk of further cognitive decline.
