As we age, our overall muscle mass tends to decline. After age 50, we lose an average of 1–2% of our muscle mass each year. Experts estimate that 5–13% of individuals aged 60–70 have sarcopenia.
The researchers looked at 181 potential risk factors, and then estimated how likely they are to predict dementia and cognitive impairment for people two, four, and 20 years after they turn 60.
Weakness comes on slowly (over months to years) in an asymmetric manner and progresses steadily, leading to severe weakness and wasting of arm and leg muscles. IBM is more common in men than women. [10] Patients may become unable to perform activities of daily living and most require assistive devices within 5 to 10 years of symptom onset.
The rate of muscle loss is dependent on exercise level, co-morbidities, nutrition and other factors.

[medical citation needed] The patient, in terms of motor skills, may have problems such as quadriceps wasting, loss of knee extension and a lesser extent of hip flexion given the femoral nerve involvement of the iliacus and pectineus muscles.
