Dementia and Alzheimer disorders causes’ cognitive impairment .the preference rate of this disorders doubles after every six years from the age of 65 years. In those between 75-79, the rate is 7%, 12% of those aged 80-84,20% to those 85-89 years and also   40% of those aged between 90 years and above (Gunning-Dixon F, 2009). It has caused age-related or normal cognitive decline. Studies have reviled that cognitive purposes drop since early childhood. The most affected areas are those that rely on capacity processing, management efficiency, and mental speediness, for example, verbal call reasoning and attention.

The same disorders bring changes in the pathological process which causes a decline in the cognitive (Sliwinski, 2003). Alzheimer’s disease causes advances in vivo imaging and cerebrospinal fluid. Test have shown the presence of beta-amyloid fibrils and plaques two decades before symptom onset. The research has shown that the brain of people with Alzheimer’s disease can be coping with an assault of the disease numerous years before everyday functional starts to suffer.

The research has also shown that Alzheimer disease often has an additional problem. This is because it is found that at later stage and with increasing age dementia may cause a person to have much more health problem (Kensinger, 2002). Dementia leads to health complication such as malnutrition falls osteoporosis, sleep problems, anxiety, agitation bone fractures, disturbed behavior, and frailty. Alzheimer disease damages and kills the brain cells, which causes the decline in a gradual loss of brain mass throughout adulthood. It distresses the connectivity among brain regions hence leading to less effective networks.
