MDS diagnostic criteria for MCI in Parkinson’s disease

The MDS diagnostic criteria for MCI in PD represent an attempt to harmonise the various definitions of MCI in PD that have been used in the past.¹ A uniform definition allows identification of:¹

• the clinical characteristics of the earliest stage of PD cognitive impairment
• the best predictors of conversion from PD–MCI to PD dementia
• the effects of PD–MCI on the quality of life and day-to-day functioning of patients with PD
• a well-characterised patient population, and a potential outcome measure, for clinical trials
• a useful clinical entity that will allow clinicians, patients, caregivers, and researchers to communicate better, thereby improving patient care and research efforts.
