In the understanding of dementia include multiple diseases of various causes.

They are all characterized by a deterioration acquired over time, progressive and irreversible manner, of all intellectual functions and personality, which affects memory, language, attention, the trial, the reasoning ability and So produces disturbance of social behavior.

We can say that it is a set of chronic diseases that evolve over a period of months at least, discovered this deterioration often haphazard manner and that the patient is not aware of it.


It is not good.

There are no therapies that help cure these disorders (except in certain dementias secondary to other processes that do have effective treatments and, therefore, cure or arrest the deterioration) so the degree of deterioration of the patient is growing.


Dementias can differentiate between primary and secondary depending on the product of another illness or not.

Among the primary stresses, their frequency, Alzheimer's disease whose cause is being investigated intensively at present.

Signs and symptoms.

The most common of all dementia is Alzheimer's disease, which was formerly known as presenile dementia (reserving the term of senile dementia for those who appeared after 65 years)

The disease occurs in older people with a slow, progressive course.

Usually, it starts with disturbances of recent memory, is often the subject can not repeat any word that you have read or heard just minutes before, but it has perfectly preserved the memory of old facts. This shortfall makes it lose the objects or forgetting where you saved.

Over time this impairment of memory becomes more pronounced, affecting longer periods, always from the present into the past.

Subsequently occurs disorientation in time and space, with disregard for the date or the inability to orient themselves in uncommon places and later in places familiar, even to ignore his own room.

They present alterations of language, being typically do not end sentences or are intersected with silences, often giving answers that do not correspond with the question. So over time present difficulties in developing business as usual, arriving after many years totally dependent on another person.

The second most frequent dementia is due to cerebro - vascular diseases (see stroke)

Risk Factors / Prevention.

Al ignored the source of most of the dementias, it is difficult to identify the risk factors and how to prevent them, but in secondary dementias, such as stroke (see stroke) that it is possible to act on the causes underlying the Most of the cases.

Diagnosis and Treatment.


The diagnosis is based on symptoms, which is usually progressive: that is, the patient enters the insanity at the time, not immediately.

Anyway we should do blood tests, electroencephalograms, CT and other evidence in certain cases to rule out any of the secondary dementias.


The treatment, rehabilitation, seeks to compel the patient to work towards her brain, especially in periods of motors and memory, enabling it to delay the onset of symptoms.

When there many types of dementia and pseudodemencias, these patients should be evaluated by a specialist because there are effective treatments for some of them.

These treatments should be instituted as soon as possible in the evolution of the disease.

Thus, we can say that some dementia can be treated specifically, such as those due to:

chronic infections such as syphilis.

Vitamin deficiency.

hormonal problems, disorders of the circulation of cerebrospinal fluid (the fluid that bathes the central nervous system composed of the brain, the brain stem and spinal cord)

In the case of dementia for which there is no specific treatment, there are palliative treatments (which reduce or eliminate the most troublesome symptoms or disabling) it is worth implementing.

It is essential support for the patient and his family as it is a problem that is beyond the scope strict sanitary becoming a social problem.


Those derived from a person who can not fend for itself, or go out on the street, or dressing, or remember anything.

The natural evolution of Alzheimer's disease leads patients to be bed, with the possibility of suffering from wounds that become infected secondarily.

Might suffer from swallowing disorders (difficulty swallowing) which leads them to states of extreme malnutrition and possibilities of pneumonia (lung inflammation) aspiration of gastric contents, often very serious.
