The dementia challenge in primary care Who in the medical community is most challenged by these issues? Most older adults receive their health care “solely” from a primary care physician More than 80% of all medical care for dementia occurs in primary care settings Ganguli et al., Ann Intern Med 2003; 138: 927-937. Borson, S. “Should Older Adults Be Screened for Cognitive Impairment?: Underdetection of Dementia in Primary Care Practice.” Medscape General Medicine, 2004-03-12. Accessed October 26, 2009.

The dementia challenge in primary care Under-diagnosis Although we can now quite accurately diagnose AD and other dementia, with autopsy results supporting the clinical diagnosis in 86-90% of cases... …fewer than 35% of people with AD or other dementia have the diagnosis in their medical record. Galasco et al., Arch Neurol 1994; 51:888-895. Boise et al., 2004; Boustani et al., 2005; Ganguli et al., 2004; Valcour et al., 2000.
The dementia challenge in primary care Why these issues challenge primary care Time constraints Reimbursement constraints Skepticism about effectiveness of medications No regular screening used Structured nature of PCP interview —Yes/no answers
The dementia challenge in primary care Why(cont.) 6.Time consuming diagnosis (By means of careful history-taking from patient/ caregiver with no one specific, universal complaint) 7.No user-friendly guidelines available (Guidelines from 1990s not updated12,13,14or have focused on treatment more than on diagnosis15) 8.No clear cut physical exam signs 9.No current specific lab or imaging test easily available
The dementia challenge in primary care Why(cont.) Dementia diagnosis opens “Pandora’s box” Difficulties in communicating with patient and caregiver16,17 12.Depression may also delay early recognition 13.Lack of knowledge about available community support services Report of the Quality Standards Subcommittee of the American Academy of Neurology.
