Approximately Half of AD Dementia Cases are Mild, One-fifth are Severe (Journal of Alzheimer’s Disease News)

Small amount of data on the severity of disease among people living with AD is currently available

Boston, MA, USA  –  What percent of patients with Alzheimer’s disease (AD) currently have severe dementia? Do more people have mild disease? Or are the majority suffering with moderate dementia? A new study published in the Journal of Alzheimer’s Disease using data from the Framingham Heart Study (FHS) sheds light on these trends.

Boston University School of Medicine researchers have found that slightly more than half (50.4 percent) of cases are mild, just under one-third (30.3 percent) of cases are moderate and 19.3 percent are severe cases. Among all participants with mild cognitive impairment (MCI) and AD, the pooled percentage was 45.2 percent for the combined group of mild AD dementia and MCI that later progressed to AD.
