According to Dr. Edward Francis, exist several types of dementias and are classified by the cause of its generation, but all have in common the destruction of brain cells.
The causes are multiple: the accumulation of amyloid in Alzheimer’s dementia, cardiovascular disease (hypertension) in vascular dementia, neurological disease (Parkinson’s disease), infectious diseases (HIV / AIDS), dementia due to toxic substances (eg alcohol), trauma (cranio-cerebral) and so on.
Currently, there are not known the factors of the illness. Currently 2 hypotheses are discussed, as predominantly a disease of genetic nature, or influenced by environmental factors
Alzheimer’s disease has 2 main categories of risk factors: genetic and environmental.
- Family: is a form of affection that genetic factors play an important role. These cases are extremely low and are considered to represent less than 5% of patients with Alzheimer’s.
- Non-family: represent more than 95% of all cases, and includes those situations where there is a hereditary transmiter highlighted.
Regarding environmental factors, it seems that diet, aluminum and viral infections contributes to Alzheimer’s dementia. Moreover, low education, low socio-economic status and cranial-cerebral trauma associated with increased risk of Alzheimer’s.
Already identified several genes whose involvement in the etiology of the disease is well established. Family genes cause Alzheimer’s dementia characterized if one form of the disease, which begins at the age of 40-50 years.
Diet, usually in people with Alzheimer’s is not needed a special diet, they are like any human, should eat healthy and balanced. However, it is recommended that people with Alzheimer’s to be cared for and supervised by professional people as they can dehydrate easily, or lose weight because of malnutrition.
Occur in older people a series of changes in food so they do not taste or smell of food, digestion works increasingly harder and cells are no longer able to efficiently use energy from food. In people with Alzheimer’s usually these problems are more pronounced.
