Neuropsychiatric symptoms, quality of life and caregivers’ burden in dementia

The objective of this research is to identify the relationship between the neuropsychiatric symptoms (NPSs) of patients with major neurocognitive disorder (mNCD), their quality of life, illness intrusiveness and the caregiver’s burden. We assessed 131 patients with mNCD. Examination methods included WHO well-being index short version, illness intrusiveness rating scale, Alzheimer’s Disease Assessment Scale-Cog, Mini Mental State Examination and neuropsychiatric inventory. The results were analysed using standard statistical tests. In our sample, the prevalence of NPSs is 100%. A significant correlation (p < 0.0001) was observed with quality of life and illness intrusiveness. Additionally, a strong relationship was observed between NPSs and the caregiver’s burden (r = 0.9). The result is significantly twice as much stronger in comparison to the relationship between NPS and cognitive symptoms (r = 0.4). This is the first study in Hungary to assess the impact of NPS on the burden of relatives and quality of life. NPS had twice stronger impact on caregivers’ burden than cognitive decline. However, further studies are needed to assess the sub-syndromes in mNCD in relation to NPS.
