Obesity, an increasingly prevalent lifestyle disease, often occurs along with poor muscle mass. This condition, called sarcopenic obesity, is evaluated based on the patients’ body mass index (BMI) and handgrip strength. Interestingly, sarcopenic obesity is known to increase the risk of cognitive impairment. Dementia, a cognitive condition where memory, thinking and social abilities progressively decline, is known to significantly affect the quality of life in elderly people. Is this condition associated with sarcopenic obesity?
