abstract = {The COVID-19 pandemic may have a disproportionate impact on people with dementia/Mild cognitive impairment (MCI) due to isolation and loss of services. The aim of this systematic review was to investigate the effects of COVID-19 lockdown on neuropsychiatric symptoms (NPS) in people living with dementia/MCI. Two authors searched major electronic databases from inception to June 2021 for observational studies investigating COVID-19 and NPS in people with dementia/MCI. Summary estimates of mean differences in NPS scores pre-versus post COVID-19 were calculated using a random-effects model was conducted, weighting cases using the inverse variance. Study quality and risk of bias were assessed by the Newcastle–Ottawa Scale. From 2730 citations, 21 studies including 7139 patients (4.0% MCI), with dementia were evaluated in the review: (60.0% female mean age 75.6 ± 7.9 years). Five studies found no changes in NPS, but in all other studies, an increase in at least one NPS or Neuropsychiatric Inventory (NPI) score was found compared to pre-pandemic. The most common aggravated NPS were depression, anxiety, agitation, irritability, and apathy during lockdown, but 66.7% of the studies had a high bias. Seven studies including 420 patients (22.1% MCI) yielded enough data to be included in the meta-analysis. The mean follow-up time was 5.9±1.5 weeks. The pooled increase in NPI score before compared to during COVID-19 was 3.85 (95% CI:0.43 to 7.27; p=0.03; I2=82.4%). All the studies had high risk of bias. These results were characterized by high heterogeneity, but there was no presence of publication bias. There is an increase in the worsening of NPS in people living with dementia/MCI during lockdown in COVID pandemic. Future comperative studies are needed to elucidate whether a similar deterioration might occur in people without dementia/MCI.},
