Similar to ageism, which is defined as discrimination against older people due to negative and inaccurate stereotypes [1], geriatrism, a new concept in medical field, reflects a negative attitude and bias toward the study of geriatrics, especially observed among students specializing in therapeutic fields such as nursing, physiotherapy, occupational therapy, speech therapy, psychology, and medicine. However, it implies a reluctance of all professionals in the therapeutic fields, including young medical doctors, to specialize in treating individuals aged 65 years and older.

Background: Total cholesterol is significantly associated with increased risk of ischemic stroke. Patients with ischemic stroke and high cholesterol levels may show better functional outcome after rehabilitation.

Objectives: To study the possible interrelations between hypercholesterolemia and functional outcome in elderly survivors of ischemic stroke.

Methods: We conducted a retrospective chart review study of consecutive patients (age ≥ 60 years) with acute stroke admitted to a geriatric rehabilitation ward in a university-affiliated hospital. The presence or absence of hypercholesterolemia was based on registry data positive for hypercholesterolemia, defined as total cholesterol ≥ 200 mg/dl (5.17 mmol/L). Functional outcome of patients with hypercholesterolemia (Hchol) and without (NHchol) was assessed by the Functional Independence Measurement scale (FIM^TM) at admission and discharge. Data were analyzed by t-test and chi-square test, as well as linear regression analysis.

Results: The complete data for 551 patients (age range 60–96 years)w ere available for final analysis; 26.7% were diagnosed as having hypercholesterolemia. Admission total FIM[1] scores were significantly higher in patients with Hchol[2] (72.1 ± 24.8) compared with NHchol[3] patients (62.2 ± 24.7) (P < 0.001). A similar difference was found at discharge (Hchol 90.8 ± 27.9 vs. NHchol 79.7 ± 29.2, P < 0.001). However, total FIM change upon discharge was similar in both groups (18.7 ± 13.7 vs. 17.6 ± 13.7, P = 0.4). Regression analyses showed that high Mini Mental State Examination scores (β = 0.13, P = 0.01) and younger age (β = -0.12, P = 0.02) were associated with higher total FIM change scores upon discharge. Total cholesterol was not associated with better total FIM change on discharge (β = -0.012, P = 0.82).

Conclusions: Elderly survivors of stroke with Hchol who were admitted for rehabilitation showed higher admission and discharge FIM scores but similar functional FIM gains as compared to NHchol patients. High cholesterol levels may be useful in identifying older individuals with a better rehabilitation potential.
