[Criteria of syndrome frailty in Parkinson´s disease]

To evaluate syndrome frailty by the Fried phenotype in patients with Parkinson's disease (PD).

Seventy-three patients over 65 years of age with Hoehn and Yahr stage 2-4 PD were tested for the presence of subjective criteria of the Fried phenotype of syndrome frailty: fatigue, difficulty in performing habitual activities, weight loss and objective criteria: grip strength and walking speed. The relationships of the objective criteria of Fried with indicators of age, sex, sports history, prescription of PD, the number of medications, blood pressure and MDS UPDRS part III scores, the severity of depression on the Beck scale and cognitive disorders on the MOCA were evaluated.

All patients complained of fatigue, difficulties in performing habitual activities. Four people noted a decrease in body weight of more than 5 kg per year. Objective criteria of Fried were absent in 38 (51%) patients, 23 (32%) people had one objective criterion: reduced walking speed (less than 0.8 m/s) or hand strength (less than 16 kg for women and 26 kg for men), in 12 (17%) people both objective criteria were reduced. The values of objective criteria of weakness were correlated with age, sex and MDS UPDRS part III total scores.

Frailty syndrome is difficult to diagnose in patients with PD due to the coincidence of complaints of the underlying disease and the syndrome. Objective criteria of the Fried phenotype suggest the presence of syndrome frailty in patients. The increase in the age of the patient, the female sex and the severity of PD are interrelated with the presence of objective criteria for the frailty of an elderly person.
