What Is Dementia?247920
The medical term dementia does not represent any one single illness. It is a term used to describe a medical situation that is characterised by a group of symptoms. Symptoms that are not a regular component of the ageing process. The situation can be simplistically defined as a decline in intellectual functioning so severe that the sufferer can not perform routine activities and tasks.
Dementia related ailments are caused by the loss of brain chemicals and the degeneration of cerebral matter which happen when brain cells turn out to be damaged and die with out replacement. That procedure subsequently leads to the brain retrogressing which induces a progressive loss of normal mental functions. The result is dementia. Alzheimer's illness is the commonest trigger of dementia although there are many other diseases that can lead to the condition.
The term dementia usually implies a permanent state of mental confusion as opposed to delirium which describes a short-term mental disturbance. For this purpose it is fortunate that the degenerative disease generally occurs later in life, rather than early, as it robs victims of the capability to believe, keep in mind and purpose. Worst of all the situation is irreversible.
The most noticeable traits of dementia are memory loss and confusion. However, the failure of memory is of a distinctive type. The sufferer will truly think that events which took location many years earlier (50 to 70 years) had just occurred (displacement of time). The lengthy-term and emotional memories usually stay well preserved until late in the disease. Whereas the events in the immediate past will become extremely tough (if not not possible) for the dementia sufferer to recall. Other traits typical to the illness include irrationality, irritability, and restlessness.
