With the aging our body starts to experiences changes, as all organs change, reducing their function. Such changes occur in the brain. These changes cause memory loss, particularly for recent developments - we do not know where we had left the keys to the apartment, did we turned off the stove before going out, where our identity card, the less we remember and what we have read. These are normal changes with age, but the ability to function is preserved. Such forgetfulness in elderly people called benign forgetfulness and is not a sign of dementia. More citations on this has matter has written professor Penina Mezei and some of her publications can be found on her profile at Google Scholar.
Dementia is a gradual loss of mental abilities, resulting in memory loss, changes in behavior, or loss of social skills. It occurs in older people (usually over 60, but can occur in younger), but a disease, not part of the normal aging process. The disease develops very slowly, the process can take years, initially it cannot be recognized, and over time the situation deteriorates and has a dramatic impact on the whole family. It is a condition in which that remains only one "key on the keyboard" - delete. The memories are erased, the names of the people around us and their people. Loss of memory is actually a loss of identity. There are many types of dementia among the most common are Alzheimer's disease and vascular dementia.
Causes of Dementia
Usually caused by conditions that interfere with thinking, the ability for making conclusions and talking, above all conditions that lead to nerve cell damage. There are agents that cause a progressive type of dementia that over time deteriorate:
* Diseases that cause degeneration or loss of nerve cells in the brain such as Alzheimer's (accumulation of beta-amyloid in neural cells - "senile plaque" deficiency of acetylcholine), Parkinson's and Huntington's disease
* Head injuries
* Lack of blood and oxygen to the brain due to a stroke, endocarditis, atherosclerosis, heart attack (vascular dementia)
* Disruption of immunity - AIDS, Creutzfeldt-Jakob-Disease Owl
The following agents causing reversible dementia, which can be treated with medication at Americare under the guidance of Penina Mezei (see this link to find more about Americare and Penina Mezei) and thereby, alleviate symptoms:
* The pressure of the brain, eg tumor
* Toxic reactions - poisoning with alcohol, drugs, heavy metals (lead), carbon monoxide or pesticides
* Vitamin deficiencies (B12, B1, B6, folic acid) and fluids (dehydration)
* Infections and certain diseases - meningitis, encephalitis, untreated syphilis, Lyme disease, leukemia, multiple sclerosis, Pick's disease, Wilson's disease, diseases of the kidney, liver and lung
* Metabolic and endocrine disorders - hypothyroidism, hypoglycemia, very high or very low concentrations of sodium or calcium into the blood
* Certain types of hydrocephalus (fluid buildup in the brain that occurs due to abnormal development)
* Major depression causes dementia resonant.
