What are the differences between dementia and forgetfulness or senility
Many people often confuse dementia with senility or forgetfulness. Senility is similar to dementia in the sense they both have to do with degradation of the brain and can include memory loss and changes in personality. However, dementia is far more serious than senility.
Dementia reduces a person’s ability to care for themselves and refers to much more severe cognitive decline.
