Dementia

Dementia (derived from Latin, originally meaning "madness" de-"without" + segment, the root of Men "mind") is a serious loss of cognitive abilities in previously unaffected person, what you can expect from normal aging. It may be static, the result is a unique global brain injury or progressive, resulting in long-term decline due to damage or disease in the body. Although dementia is far more common in the geriatric population, it can occur at any stage of adulthood.
This age cutoff is defining, as similar sets of symptoms due to organic brain syndrome, or dysfunction, given different names in the young population, as an adult. By the end of the 19th century, dementia was much broader clinical concept. Until the second half of the 20th century, dementia, old age or senility called and treated as a normal aspect of aging rather than a specific disease, caused by Alzheimer's disease is regarded as a rare disease of middle age, to a neurologist Robert Katzmann communication signals between the "senile dementia "and Alzheimer's disease.
Dementia nonspecific illness syndrome (set of signs and symptoms) in the affected areas of cognition may be memory, attention, language and problem-solving. As a rule, must submit to at least 6 months of diagnosis, cognitive dysfunction, which are seen only for short periods, in particular, is less well known than the ravings of weeks. In all types of general cognitive dysfunction, higher mental functions first affected in this process.
There are mainly in the later stages of the disease, victims may be disoriented in time (not knowing what day of the week, month or even year, that is), in a place that I do not know (where they know), and in person (and not who they are and others around them). Dementia, though often treatable to a degree, usually for reasons that are progressive and incurable.
Symptoms of dementia can be classified as either reversible or irreversible, depending on the etiology of the disease. Less than 10% of cases of dementia due to causes which could now be reversed with treatment. The reasons are many different specific disease processes in the same way that symptoms of organ dysfunction, such as respiratory distress, jaundice, or pain of many causes.
Without careful study of history, the term syndrome of delirium (often within a few days to several weeks) can be easily confused with dementia, because they have all the symptoms common to save time. Some mental illnesses, including depression and psychosis can cause some symptoms that are different from both delirium and dementia needs.
Chronic use of substances such as alcohol can also predispose the patient's cognitive changes suggestive of dementia, even though moderate consumption may have a protective effect.
