<p>Cognitive impairment and frailty are often found in older people, and they appear to be related to each other. However, little is known about the prevalence and transition to frailty in older adults with cognitive impairment, especially in the Brazilian population. The present study aimed to determine the prevalence and transitions between frailty states in a cohort of older adults with cognitive impairment followed prospectively for 1 year. A cohort of 59 community-dwelling older adults (aged &gt; 65 years) with I— cognitive impairment was evaluated. Individuals were classified as frail by the presence of 3 or more of the following criteria: unintentional weight loss; reduced grip strength; exhaustion; slowness; and low physical activity level. Individuals meeting 1 or “ 2 criteria were classified as prefrail, and those meeting 0 criteria as nonfrail. Cognitive function was assessed by the Mini-Mental J2 State Examination, and severity, by the Clinical Dementia Rating scale. Of 59 older adults evaluated at baseline, 28 (47.5%) ^ were classified as frail, 28 (47.5%) as prefrail, and only 3 (5%) as nonfrail. Over 12 months, 33.3% of participants transitioned from prefrail to frail. The present study showed a high prevalence of frailty in older adults with cognitive impairment and, within 12 months, new cases of frailty were identified in this population. Therefore, more research is needed to further investigate the relationship between cognitive decline and frailty.</p>
