Brief Summary: Despite the availability of numerous cognitive assessment tools, cognitive impairment related to dementia is frequently under-diagnosed in primary care settings. The investigators have developed a 5-minute cognitive screen (5-Cog) coupled with a decision tree to overcome the technical, cultural and logistic barriers of current cognitive screens to improve dementia care in primary care patients with cognitive concerns.

Detailed Description: Despite the availability of numerous cognitive assessment tools, cognitive impairment related to dementia is frequently under-diagnosed in primary care settings, and is a more prevalent problem among older African-Americans and Hispanics than among older whites. Missed detection delays treatment of reversible conditions as well as provision of support services and critical planning. To overcome the technical, cultural and logistic barriers of current cognitive screens and dementia care in primary care settings the investigators have developed a 5-minute cognitive screen (5-Cog) coupled with a decision tree to identify persons at high risk of developing dementia in multi-ethnic primary care populations.

The 5-Cog includes the Picture based Memory Impairment Screen (PMIS), Motoric Cognitive Risk syndrome (MCR), and a brief non-memory picture based test (Symbol Match). The cognitive assessment will sort patients with 'cognitive impairment' from those with 'no cognitive impairment'. It is coupled with a decision tree to guide clinicians through the follow up based on results of the 5-Cog.

The primary objective is to test the ability of the 5-Cog and decision tree paradigm to improve dementia care in primary care patients with cognitive concerns.

The investigators propose a single-blind, randomized clinical trial (RCT) in 1,200 older primary care patients with cognitive concerns who will be randomized to receive the 5-Cog (intervention group) or a 5-minute health literacy and grip assessment (active control group). Non-physicians will administer the intervention and control assessments in primary care sites and will provide results for both arms to the treating physician with a decision tree follow up guide based on the results of the assessments.

Arm && Interventions

Group	Intervention	Description
5-Cog	5-Cog	The 5-Cog coupled with a decision tree is a simple, 5-minute procedure that will identify older persons with cognitive impairment in primary care settings, and flag them for further evaluation. The 5-Cog includes the Picture Memory Impairment Screen (PMIS), Motoric Cognitive Risk syndrome (MCR), and the Symbol Match test. The 5-Cog will be given after randomization and before the patients sees the physician. The 5-Cog will sort patients with 'cognitive impairment' from those with 'no cognitive impairment'. After completing the 5-Cog, the non-physician tester will send a message through the Electronic medical record (EMR) system to provide the physician with the 5-Cog results and guide the them through the follow-up based on the results.
Health Literacy & Grip Assessment	Health Literacy & Grip Assessment	The 5 minute assessment includes the Short Assessment of Health Literacy (SAHL) and a grip assessment measured using a handgrip dynamometer. After completing the SAHL and grip assessment, the non-physician tester will send a message through the EMR to provide the physician with the results from the assessments and guide the them through the follow-up based on the results.

Primary Outcome Measures

Name	Time	Method
New Occurrence in Dementia Care-A Composite Endpoint Including New Cognitive Diagnoses, Laboratory Investigations Related to Cognitive Impairment, New Dementia Prescriptions, and Cognitive Related Referrals.	90 days after the participant is randomized	Dementia care is defined as the occurrence of any of the following endpoints following the screening visit. The endpoint is the number of participants who received 1 or more of the following orders: 1. Any new diagnosis of dementia (relevant International Classification of Diseases (ICD)-10 codes) or Mild Cognitive Impairment (MCI) documented in the EMR. 2. Tests ordered for reversible causes of cognitive impairment as recommended by the published guidelines of professional societies (i.e. thyroid function tests, B-12 level, Syphilis Panel, human immunodeficiency virus (HIV) test, computed tomography (CT) or Magnetic Resonance Imaging (MRI) scans) documented in the EMR. 3. Any new prescriptions for dementia medications (i.e. Donepezil, Aricept, Memantine, Namenda, Rivastigmine, Exelon, Galantamine, Razadyne, Donepezil, or Namzaric) documented in the EMR. 4. Referral for cognitive/dementia evaluation by specialists (i.e. Neurology, Geriatrics or Psychiatry) documented in the EMR.

Secondary Outcome Measures

Name	Time	Method
New Occurrence of in Health Care Utilization	6 months after the participant is randomized	Utilization is defined in terms of emergency room visits and hospitalizations following the screening visit. The number of participants who went to the emergency room or had a hospitalization in the 6 months following the screening visit are presented in aggregate.
