New Alzheimers variant may often go misdiagnosed

By Amanda Stewart,

An Alzheimer’s variant that is rather common among Alzheimer’s patients may be misdiagnosed and even ignored.

The variant is called hippocampal sparing AD and was found in 11 percent of the 1,821 brains studied, according to Headlines and Global News.

Those who are affected with this variant are generally men and are often affected with AD at a younger age. This specific type of AD is usually characterized by frequent angry outbursts, the feeling that their limbs do not belong to them and are controlled by an unknown force as well as visual disturbances.

Around 5.2 million Americans have Alzheimers, which means somewhere around 600,000 people probably have this variant of the disease, according to WebMD. Patients with the hippocampal sparing Alzheimer’s decline much more quickly than those with the well-known form of Alzheimer’s.

"Many of these patients, however, have memories that are near normal, so clinicians often misdiagnose them with a variety of conditions that do not match the underlying neuropathology," says the study's lead author, Melissa Murray, Ph.D., an assistant professor at the Mayo Clinic.

This study has not yet been published, it has only been presented at a medical meeting.
