CAMH - McMaster Collaborative Care Initiative For Mental Health Risk Factors In Dementia

The investigators will enroll 150 participants overall (CAMH and McMaster). Seventy-five will be cases who will be enrolled into the ICP arm of the study and these will be patients born in the calendar year 1951, 1953 or 1955. The investigators will enroll an additional 75 controls that were born in the calendar year 1950, 1952 or 1956.

Patients of general practitioners being seen at primary healthcare clinics in the Greater Toronto Area and in Hamilton, who were born in the calendar year 1950, 1951, 1952, 1953, 1955, or 1956 will be consented and screened for anxiety, depression, and Mild Cognitive Impairment (MCI).

If patients born in 1951, 1953 and 1955 reach a threshold level of anxiety, depression, or MCI symptom burden and have a confirmed diagnosis, rather than receive treatment as usual, the participants will be enrolled into an Integrated Care Pathway (ICP), which offers evidence-informed treatment for the management of these syndromes in a routine, algorithmic fashion. All enrolled cases entered in the study will be provided with general interventions that address lifestyle and medical factors that both contribute to these syndromes and are thought to predispose patients to develop dementia. If the symptom burden is severe enough, based on standardized assessments, evidence-based psychopharmacology (a trial of sertraline and/or venlafaxine) will also be offered, with a standardized titration schedule. Collaboration will be built into the ICP - a psychiatrist will be present at the clinic and in contact with primary care providers to provide patient- and physician-level support, consultation, and episodes of care as necessary. Rates of anxiety, depression, and MCI diagnosis/detection, time to treatment initiation, and improvement in symptom burden will be assessed.

If patients born in 1950, 1952 and 1956 reach a threshold level of anxiety, depression, or MCI symptom burden, these individuals will form our comparison group and will receive treatment as usual (TAU).
