Machine learning finds four behavior symptom profiles tied to early dementia processes

Behavioral changes—such as anxiety, depression, irritability, apathy or agitation, collectively known as neuropsychiatric symptoms—may appear long before a dementia diagnosis. A new study from Karolinska Institutet and the University of Perugia, published in Alzheimer's & Dementia, shows that these symptoms form recognizable patterns across older adults ranging from cognitively unimpaired to those with dementia.
