AB  - BACKGROUND: The Great East Japan Earthquake triggered accidents at the Fukushima 
      Daiichi Nuclear Power Plant, becoming the first complex disaster that included 
      both a natural and a nuclear power disaster. This study examines how complex 
      disasters affect patients with dementia. METHODS: Participants included the 331 
      people diagnosed with dementia out of the 2482 new patients (between January 2008 
      and December 2015) at a psychiatric hospital located in the indoor sheltering 
      zones nearby mandatory evacuation zones. Medical records were retrospectively 
      examined to identify the number of new patients with dementia, the severity, 
      their chief complaints, and the behavioural and psychological symptoms of 
      dementia (BPSD) types. BPSD were classified into the hyperactive BPSD group and 
      the hypoactive BPSD group. The hyperactive BPSD group was further subdivided into 
      the hyperactivity-impulsivity-irritability-disinhibition-aggression-agitation 
      group, which exhibited agitation, disinhibition, and irritability, and the 
      psychosis group, which exhibited delusions and hallucinations. The hypoactive 
      BPSD group included depression, inactivity, apathy, and anxiety. Results were 
      divided into the period before the complex disaster (2008-2010) and after 
      (2012-2015) and were compared. In addition, the post-complex-disaster period was 
      subdivided into the early phase (2012-2013) and the late phase (2014-2015). 
      RESULTS: The proportion of new patients with dementia increased significantly 
      after the disaster. Although there was no change in patients' age and the 
      disease's severity, the proportion of patients whose chief complaint was BPSD 
      increased significantly after the disaster. Furthermore, there was a significant 
      increase in the 
      hyperactivity-impulsivity-irritability-disinhibition-aggression-agitation group 
      in the early post-complex-disaster phase and a significant increase in the 
      psychosis group in the late post-complex-disaster phase. CONCLUSION: This complex 
      disaster caused increased consultations from patients with dementia and increased 
      BPSD. Additionally, it increased participants' symptoms of agitation and 
      irritability in the early post-complex-disaster phase and the proportion of 
      hallucinations and delusions in the late post-complex-disaster phase.
