abstract = {The aim of the present study was to investigate the
association between modifiable factors and symptom
progression in people with dementia over a period of up to
eight years.We used data from a German cohort of
community-dwelling individuals who screened positive for
dementia in primary care. They underwent comprehensive
annual in-home-assessments for up to eight years by
specially trained nurses. The following modifiable factors
were considered: low education, hearing impairment (and its
treatment), hypertension (and its treatment), alcohol
consumption, obesity, smoking, depression, social isolation,
physical inactivity, diabetes (and its treatment) and visual
impairment. We used multilevel growth curve models to
investigate the role of modifiable risk factors on cognitive
trajectories and trajectories in daily functioning.Higher
education was associated with higher cognitive status at the
beginning of the study, but also with faster cognitive
decline over time. People receiving anti-diabetic
medications showed slower cognitive decline, while
depression and visual impairment were associated with lower
levels of daily functioning at baseline and faster cognitive
decline over the eight-year study period. We found no
association of hearing impairment (or its treatment),
hypertension (or its treatment), alcohol consumption,
obesity, smoking, lack of social support and physical
inactivity with the rate of symptom progression.Our study
found evidence that several potentially modifiable risk
factors influenced symptom progression in dementia over up
to eight years. Cognitive reserve through education showed a
positive effect, which reversed over time, and depressive
symptoms were linked to less favorable progression. Treating
comorbidities like diabetes and visual impairment may
positively impact dementia symptoms. Modifiable risk factors
are promising targets for tertiary prevention and should be
explored further.},
