Dementia symptoms have different faces. It depends on the cause of the problem and the nature of the affected brain regions. The earliest symptom of dementia is memory loss, which is quite apparent. Other major symptoms of dementia may include - significant decrease in working memory, unable to recognize places and people, unable to produce appropriate words, experiencing difficulty in performing calculation, unable to carry out simple tasks, such as writing a note, follow an instruction, having difficulty in executing decision, experiencing difficulty in mood and behavior management, unable to keep personal care, and the like.

There are certain types of dementia that cause major and critical symptoms. For example, people suffering from dementia accompanied by Lewy bodies experience highly detailed visual hallucinations. They have a strong tendency to fall down. On the other hand, people with frontotemporal dementia may have significant changes in their personality, so they exhibit unusual behavior. These types of people seem to be extremely careless for others, or others may find them rude. These people tend to expose themselves and have a strong tendency to make comments on sexually explicit things.

At the initial stage, dementia symptoms may only be limited to recalling events or remembering any numbers. Many people simply ignore these symptoms as they find them non-interfering to their lives. But as soon as the problem progresses, it takes the disastrous shape. Gradually it starts creating interferences with the quality of life. People with advanced dementia symptoms become absolutely zombie and become unable to perform minimum level of self care and self management. They are only able to speak a single word instead of a full sentence.

If dementia symptoms appear all of a sudden, these may give the hints of developing vascular dementia. Otherwise, it also can be the symptoms for delirium -short term confusions, which may happen as a result of newly occurred disease. So, not all dementia-like symptoms are actually dementia symptoms in practice.
