The U.S. Preventive Services Task Force said it could neither recommend nor oppose cognitive screening for older adults because there is insufficient scientific evidence of the practice’s benefits and harms. Soo Borson, professor emerita and developer of the Mini-Cog, a brief screening tool for cognitive impairment designed for use in primary care and other non-specialist settings, warned that there aren’t enough specialists to handle the demand that would arise if universal screening for cognitive impairment were implemented.
