Sometimes they may experience certain behaviours such as withdrawn, irritability, agitation, wandering and get lost.

In the severe stage, person with dementia may be totally dependent on care giver to provide personal care such as showering, going to toilet and eating. Person with dementia may be talking less and eventually lead to mutism.     

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.
