The first sign of Dementia typically is mild forgetfulness. People with mild Dementia may have trouble remembering recent events or take longer than before to finish a task. Simple math problems may become hard to solve. A person may seem healthy but is actually having more and more trouble making sense of the world around him or her. The early signs of dementia can often include difficulty performing tasks that were easily performed in the past, getting lost in routine activities, difficulty remembering names of familiar objects, misplacing things, and loss of interest in things that used to be enjoyable. Such difficulties could be due to any variation of dementia. A doctor should be consulted to make a diagnosis.

As people get older, changes occur in all parts of the body, including the brain. As a result, some people may notice that it takes longer to learn new things, they don't remember information as well as they did, or they lose things like their keys. These usually are signs of mild forgetfulness, not serious memory problems.

Emotional problems, such as stress, anxiety, or depression, can make a person more forgetful and may be mistaken for dementia. Some health issues, such as medication side effects, vitamin B12 deficiency, chronic alcoholism, tumors, and blood clots in the brain, can cause memory loss or possibly dementia. A doctor should treat medical conditions like these as soon as possible.
