Extreme behavioural and psychological symptoms of dementia: a case study

Abstract

Abstract Background The seven tiered behavioural and psychological symptoms of dementia (BPSD) model of service delivery has been used by inpatient units. The classification of each tier is broadly defined and not always agreed upon by clinicians. The case study uses novel approach by combining the BPSD classification criteria with clinical presentation to identify the clinical characteristics of the case and match these characteristics against the BPSD classification. This process was enhanced by using case specific measures such as the Neuropsychiatric Inventory (NPI) and Cohen Mansfield Agitation Inventory (CMAI) scales and key clinical data. Case Presentation A case study of 76 year old male diagnosed with mixed Alzheimer’s and Vascular dementia. The clinical presentation of the symptomatology was deemed to be extreme, thus fitting into the seventh tier (Extreme) of the BPSD model of service delivery. The case is considered to fit into the Extreme BPSD category given the high levels of aggression, which were consistently reflected in high scores on NPI and CMAI, as well as long length of inpatient stay (over 3 years). The average number of Pro re nata (PRN) psychotropics medications per month was 56 and seclusion episodes of 6 times per month, with each episode lasting on average 132 min shows severity of behaviours. His level of aggression had resulted in environmental damage and staff injuries. Conclusion We recommend patient clinical characteristics, relevant hospital data and specific measures should be used to develop consensus around defining and classifying cases into Extreme BPSD.
