It is administered to both the patient and his/her relatives. In addition to psychological signs such as delusions, hallucinations, anxiety, inattention, anger, aggression, excessive happiness, behavioral signals such as increased/decreased appetite, abnormal motor activities, abnormal sleep/night states, self-care neglect and hoarding are also assessed through these inventories.
The Frontal Behavior Inventory (FBI) was developed specifically for the assessment of behavioral disorders in patients with frontotemporal dementia. The FBI is an inventory developed to detect positive and negative behaviors and personality changes. It is a widely used test abroad to assess behavioral and personality changes in patients with frontotemporal dementia and other dementias. This test consists of 22 questions. The items consist of negative behaviors (apathy, aspontaneity etc.) and positive behaviors (disinhibition) (perseveration, irritability etc.). The caregiver is interviewed and asked to compare the patient's pre-disease state with the current state. According to the severity of the behavior, it is scored out of 4 as none, moderate, moderate and severe.
