Methods Papers describing neurobiological indices related to behavioral symptoms of dementia were reviewed. Papers comparing indices in persons exhibiting aggression and persons exhibiting agitation were selected for this review. Results The survey found seven papers which compared neuroanatomical indices and three papers which compared neurochemical indices. The neuroanatomical indices differentiating agitation and aggression included changes in brain perfusion, sizes of brain areas, distribution of neurofibrillary tangles, and white matter changes. The neurochemical indices differentiating agitation and aggression included relationships with neurotransmitter variables and the cell count in the locus coeruleus. Conclusion Despite the small number of papers and some methodological problems, the presented information clearly indicates that aggression and agitation are two distinct unrelated syndromes in persons with dementia.

DOI10.14302/issn.2470-5020.jnrt-18-2554 Behavioral and psychiatric symptoms of dementia are very common and are often more distressing than consequences of cognitive impairment. These symptoms are associated with increased healthcare use, earlier institutionalization 1. excess morbidity and mortality, greater caregiver distress and depression 2. While the psychiatric symptoms are well defined and use uniform terminology, there is a confusion about %U https://www.openaccesspub.org/jnrt/article/1011
