Researchers have identified a total of five subgroups among Alzheimer’s patients, according to a new study published in the journal Nature Aging on Jan. 9.

Different groups may require different treatment options, as noted in a press release from Alzheimer Center Amsterdam, Amsterdam UMC and Maastricht University.

“Previously, it was thought that Alzheimer’s disease is one disease, and that treatments being developed will work similarly for all individuals,” lead researcher Betty Tijms, associate professor of neuroscience and brain imaging at Amsterdam UMC, told Fox News Digital in an email.

“Each subgroup may need its own treatment, or version of a treatment, or combination of treatments, in order to be effective with the least side effects,” she said.

To confirm these findings, Sexton called for additional research with larger study groups that “accurately represent the diversity of the at-risk and affected populations.”
