A simple smell test can help detect memory problems

Specialists from the Massachusetts General Hospital have studied how the ability to distinguish odors is related to brain function. It turned out that even small changes in the perception of scents can indicate the beginning of problems with cognitive functions. This discovery could be the basis for early diagnosis of neurological diseases.

The procedure is simple: a person is given cards with odors that need to be distinguished, remembered and named. This method allows you to assess the state of memory and perception, without resorting to complex and expensive examinations. The test can be completed independently at home, which makes it accessible to a wide audience.

Detecting cognitive impairment in the early stages makes it possible to adjust lifestyle and slow down the development of the disease. If memory problems are detected early, you can begin prevention by changing your diet, adding physical activity and controlling stress levels.

Testing is especially useful for older adults who notice decreased concentration and forgetfulness. The study found that participants with memory complaints performed worse at identifying odors compared to those who had no such difficulties.

The authors plan to expand the research by supplementing the test with neuropsychological analyses and observing participants over a longer period of time. If the link between olfaction and cognitive health is confirmed, this method could become a standard tool for early diagnosis.
