Many people do not know what is dementia. They think it is a disease. However, it is not as dementia occurs due to other neurological disorders like Alzheimer's disease, Huntington's disease, Parkinson's disease or multiple small strokes. But, one thing is common in all dementia patients and that is irreversible loss of mental faculties, thought process, reasoning, ability to communicate and planning. In addition, a person suffering from dementia will also tend to have hallucinations, delusions and paranoia.
Usually people develop dementia as a result of Alzheimer's disease. However, it can also occur due to other causes and disorders. When a person develops dementia due to Alzheimer's disease, he or she will suffer from failure of cognition due to destruction of the brain cells. This is a progressive disease and full blown dementia will set on with time. The person will then suffer from extreme personality changes and exhibit all signs of delusions, hallucinations and paranoia. In addition, the person will not be able to socialize or mingle with others.
In order to have a confirmed diagnosis of dementia, the doctor would have to do several psychological tests to get an inkling of the person's cognitive functioning. Remember, dementia not only affects memory, it also affects a person's abilities to make decisions. In addition, the person will have personality changes and will face difficulties in holding conversations or remembering words. When the dementia reaches an advanced stage, the person ends up losing the meaning of time and space.
There is no available treatment for dementia currently. However, medications can be given to alleviate some of the symptoms.
