Study summary

This project is based on a three-year program that aims to improve the knowledge of the socioeconomic consequences of dementia in Norway. By including patients with and without dementia in four different cohorts (from nursing homes, from memory clinics, home-dwelling persons with dementia and elderly persons without dementia), the project's aim is to describe the course of dementia, the economical cost of dementia and to look into possible risk factors for dementia.

Groups and cohorts

  • Memory clinic

    People visiting a memory clinic at Ullevål University Hospital, St Olav Hospital or Innlandet Hospital Trust (n=400). The patients will be assessed three times over a three-year follow-up. Baseline inclusion started in January 2010. The final assessments will take place in spring 2014.

  • Nursing homes

    People admitted to a nursing home recruited from municipalities in Hedmark, Oppland, Nord-Trøndelag and Bergen (n=1000). Baseline assessments take place when the person is admitted to the nursing home. The patients will be assessed every six months over a three-year follow-up period. The first participant was included in March 2012, and baseline inclusion will be completed in December 2013.

  • In-home care

    People 70 years of age or older receiving in-home care recruited from municipalities in Hedmark, Oppland, Oslo, Østfold and Buskerud (n=995). The patients will be assessed three times over a three-year follow-up period. Baseline inclusion started in April 2009 and the final assessments will take place in December 2013.

  • People without dementia

    People without dementia recruited from Nord-Trøndelag, Drammen and Oslo (n=400). The participants will be assessed three times over a three-year follow-up period. Baseline inclusion will take place in autumn 2012 and the last follow-up will take place in autumn 2015.

What researchers measure

Primary outcomes

  1. Cost of dementia

    The cost of dementia is assessed with the Resource Utilization in Dementia (RUD) (Wimo et al. 2009), for a period of three years for all the four cohorts. The nursing home cohort is assessed at baseline and every 6 month for three years, the other three cohorts are assessed three times over a three-year follow up period.

    Time frame: 3 years

Secondary outcomes

  1. The course of neuropsychiatric symptoms

    The course of neuropsychiatric symptoms (depression, anxiety, psychosis, aggression, apathy, and cognition, are assessed with standardized assessment Tools. The nursing home cohort is assessed at baseline and every 6 month for three years, the other three cohorts are assessed three times over a three-year follow up period.

    Time frame: 3 years

  2. Quality of Life in persons admitted to nursing homes

    Quality of Life is assessed with standardized assessment Tools. The nursing home cohort is assessed at baseline and every 6 month for three years, the other three cohorts are assessed three times over a three-year follow up period.

    Time frame: 3 years

  3. Prescription of medication

    Prescription of medication is recorded at baseline, and the amount of medication used is recorded throughout the study period. The nursing home cohort is assessed at baseline and every 6 month for three years, the other three cohorts are assessed three times over a three-year follow up period.

    Time frame: 3 years

  4. DNA polymorphism

    DNA samples are collected for the nursing home cohort, and they are assessed for genetic polymorphism previous associated with dementia. The results are used as covariates in the analyses of the course of the symptoms and to look for risk factors for dementia.

    Time frame: At baseline

  5. Organizational factors of the nursing homes

    Organizational factors of the nursing homes and variables associated with the staff of the nursing homes will be collected at baseline, and the data will be used to explore associations between nursing home characteristics and the course of the symptoms in the patients.

    Time frame: At baseline
