Since impaired neurons are not capable of reproducing or renewing, the changes are irreversible, and any outcomes they produce are often irreversible (p. 118). Generally, it is not possible to halt the progression of the illness, because no cure is available. Hence the condition could affect other nerve cells, slowly but unavoidably resulting in the behavioural disorders and incapacities called ‘dementia’ (Esiri & Trojanowski 2004, 1-2). The outcomes could be illustrated as an organised deterioration of the mind through which the individual becomes more and more helpless, insecure, difficult, unaware, and inadequate. With an aging population that is drastically enlarging, there is the likelihood that dementia will become massively prevalent in the 21st century.
