absorption may be so intense that the individual may not know the month<br />

5. Delusions and hallucinations; in most cases the former<br />

characteristics are accompanied by <strong>de</strong>lusions. The most common are<br />

beliefs that other persons are trying to control his thoughts, he may<br />

become suspicious of friends (paranoid), this is the reason why Robert<br />

Kennedy was assassinated.<br />

The results of schizophrenia are many and varied, but these are the<br />

main characteristics. Not everybody has the same opinion about the causes<br />

of schizophrenia, but some factors have certainly influence on<br />

schizophrenics. Disturbed home life and early trauma are frequently found<br />

in the background of schizophrenics. The early <strong>de</strong>ath of one or more<br />

parents, emotionally disturbed parents and strife between parents are found<br />

with greater frequency in the background of schizophrenics.<br />

3. Alzheimer's Disease<br />

Alzheimer's Disease is a progressive <strong>de</strong>generative disease of the<br />

brain now consi<strong>de</strong>red a leading cause of <strong>de</strong>mentia. Alzheimer's disease<br />

was first <strong>de</strong>scribed by the German neuropathologist Alois Alzheimer in<br />

1906, it affects an estimated 2.5 to 3 million people in the United States. In<br />

the United Kingdom, the number of individuals with this condition is<br />

estimated to rise to over 1 million by the year 2010. Percentage rates<br />

(cases per 100 individuals of 65 years and over) worldwi<strong>de</strong> vary<br />

consi<strong>de</strong>rably between 0.6 in China to 10.3 in Massachusetts, United States.<br />

The inci<strong>de</strong>nce of the disease increases with advancing age, but there is no<br />

evi<strong>de</strong>nce that it is caused by the aging process.<br />

The average life expectancy of people with the disease is between<br />

five and ten years, although many patients now survive 15 years or more<br />

due to improvements in care and medical treatment. The cause of this<br />

disease has not been discovered, although palliative therapy is available.<br />

The ability of doctors to diagnose Alzheimer's disease has improved in<br />

recent years, but this remains a process of elimination and final diagnosis<br />

can be confirmed only by post-mortem. Alzheimer's patients show nerve<br />

cell loss in the parts of the brain associated with cognitive functioning. The<br />

hallmark lesions of Alzheimer's disease inclu<strong>de</strong> the formation of abnormal<br />

proteins. Alzheimer's disease is also characterized by profound <strong>de</strong>ficits in<br />

the brain's neurotransmitters which has been linked with memory function.<br />
