Frequency of Fibromyalgia Syndrome in Elderly Patients Aged 80 and Above and Its Relationship With Geriatric Parameters

The presence of fibromyalgia will be evaluated using the 2016 American College of Rheumatology diagnostic criteria.

Neurocognitive assessment will be done with Mini Mental State Examination (MMSE). MMSE test is a short screening test with 11 questions and 30 points. MMSE is completed in approximately 10 minutes and evaluates orientation, memory, attention, calculation, recall, language, motor function and perception, visual-spatial abilities. 24-30 points is normal, 18-23 points is mild dementia, 17 and below is compatible with severe dementia.

Mood assessment will be assessed with the Geriatric Depression Scale-short form (GDS-SF). GDS-SF consists of 15 questions that patients answer yes or no. Scoring is done as the number of yes answers, and the total depression score is calculated from the sum of the scores. Scores between 0-9 are considered "normal", scores between 10-19 are considered "mild depression", and scores between 20-30 are considered "severe depression".

The assessment of daily living activities will be assessed with the Lawton-Brody Instrumental Activities of Daily Living Scale (IADLS). IADLS consists of 8 questions that include information on using the telephone, preparing meals, shopping, doing daily housework, doing laundry, being able to get on a vehicle, being able to use medications, and managing money. 0-8 points are evaluated as "dependent," 9-16 points as "semi-dependent," and 17-24 points as "independent."

Balance and walking assessment will be assessed with the Tinetti Performance-Oriented Mobility Assessment (POMA). POMA assesses balance ability and walking under 2 main headings. The first 9 questions are about balance, the next 7 questions are about walking. Calculation of the survey score; the total score of the first 9 items gives the balance score, the total score of the next 7 items gives the walking score, and the sum of the balance and walking scores gives the total POMA score. Individuals with a score of 18 and below are considered to have poor balance and walking.

Nutritional assessment will be evaluated with the Mini Nutritional Assessment questionnaire-short form (MNA-SF). MNA-SF consists of 5 subheadings; those with 12-14 points are considered "no risk of malnutrition", those with 8-11 points are considered "at risk of malnutrition" and those with 0-7 points are considered "malnourished".

Frailty will be assessed using the Clinical Frailty Scale (CFS). CFS is graded from 1 to 9. The higher the score, the greater the frailty.

The assessment of daily living activities will be assessed with the the Barthel Index (BI) scale. BI consists of 10 questions that evaluate feeding, washing, self-care, dressing, defecation control, urinary control, going to the toilet, the ability to get from bed to a wheelchair, mobility status such as walking or being wheelchair dependent, and climbing stairs. 0-20 points are considered as completely dependent, 21-61 points as severely dependent, 62-90 points as moderately dependent, 91-99 points as slightly dependent, and 100 points as completely independent.
