GERIATRIC SYNDROME IN OLD ADULTS, AROMATHERAPY AND MUCH MORE – HOW DOES THE SENSE OF ODOR REFLECT TO THE BRAIN?

In line with age-related decline in physiological function and other related consequences, the person's care
It is defined as geriatric syndrome. Some symptoms of geriatric syndrome
symptoms associated with acute illness, such as falling and shortness of breath; over 75 years old
symptoms related to chronic diseases, such as cognitive and respiratory impairment in the middle-aged population, and
loss of appetite, malnutrition. Often interrelated in older adults
multiple symptoms coexist. Existing medical conditions that do not combine symptoms
practices often cause undesirable side effects. Muscle and brain functions

functional loss can also affect the function of sensory organs. human olfactory mucosa

it is thin. Decreased sense of smell in humans in recent years has been associated with cognitive dysfunctions.
It was considered an early sign. Studies on the sense of smell
It has been shown to be a part of brain function and associated with nervous system diseases.
A recent study in Japan found that aromatherapy was especially effective for shortness of breath,
symptoms of geriatric syndrome, such as cognitive decline, instability, and a tendency to fall
examined its effects on In addition, the use of aromatherapy for medical care in the elderly
demonstrated the potential to extend healthy life expectancy.
Patients with chronic respiratory disease, while performing body movements in daily life
they feel stuck. Therefore, they tend to involuntarily reduce their movements.
In short, they unconsciously reduce the effort as much as possible. This behavior; physical activity, capillary bed
It leads to a decrease in the density and number of mitochondria, thus aggravating the disease.
Reversing this situation with respiratory rehabilitation including exercises in these patients
It is possible and very important. In a study of patients with chronic lung disease
The effect of menthol on olfactory stimulation and airflow in patients was investigated. from 32 patients
while one group received volatile strawberry menthol, the other group was designated as a placebo and attended the fragrance sessions.

changed and the feeling of dyspnea (shortness of breath) decreased.
According to the data of the World Health Organization, the number of dementia patients by 2050

showed that the key to remembering is olfactory memory.
Another symptom most common in older adults with dementia is persistent falling.
Among the emergency admissions, the number of fall-related accidents among older adults is quite high.
Changing sensory and motor systems in response to changing task and environmental demands
ability is called postural control. Postural control with various sensory inputs
are related. The main ones are visual and vestibular inputs. Visual for a healthy balance
Input is very important. Visual input is based on both the head position and the body during movement.
It contains information about the relationship between the environment. Vestibular input, standing with eyes closed
provides. In addition, it allows the evaluation of verticality perception, allowing walking, sliding or

reaches the sensory cortex area. Then the information coming from every part of the body
sends it to an area where it is integrated and forwarded. (somatosensory convergence area) Briefly,
The thalamus is the intersection point of both various stimuli and information from the sense organs.
The results of the study on the relationship between geriatric syndrome and aromatherapy in Japan,

It is a proven prediction. Numerous sensory and motor functions for posture and movement control

As a result, this research, which marked the year 2021, shows that aromatherapy can be used in older adults.
