Memory loss is unusual forgetfulness. May not able to remember the new incidents, recall more memories of the past or both . Memory loss can be distressing for the person affected as well as for their family.

Mild cognitive impairment is a syndrome defined as cognitive decline greater than expected for an individual’s age and education levels but that does not interfere notably with activities of daily life. Age related changes in cognitive function vary considerably across individuals. Some cognitive functions appearing more susceptible than others to the effect of aging.

DISCUSSION:

The present study was designed to assess the memory loss and cognitive impairment for the elder peoples. The investigator adopted descriptive research design. The data collected for the study were analyzed statistically and discussed below based on objectives.

i) Demographic Description: Demographic variables included Age , Sex , Education , Monthly income before coming to the old age home , Marital status , Occupation before coming to the old age home , Duration of stay in the old age home , Family history of mental illness , Source of income .

Out of 60 elderly majority of the people 26 ( 43. 33%) were between the age group of 76 – 80 yrs , regarding the sex 36 ( 60%) people are males , regarding the educational status 50 ( 83. 33 %) people had primary education , regarding the monthly income 46( 76. 66%) people are getting RS , 3000-5000, 39 ( 65%) people married , 24 ( 40%) people are in private job , 30 ( 50%) people are staying 1-2 years in the old age home , 55( 91. 66% ) people are not having family history of mental illness , 20 ( 33. 33%) people are having source of income from the children.

1) The first objective of the study was to assess the memory loss and cognitive impairment among elder people.

Among 60 samples 1 (1. 66%) of them scored between 61-80 (Mild memory loss), 19 (31. 66%) of them scored between 41- 60 (Moderate memory loss), 40 (66. 66%) of them scored between 21- 40 (Severe memory loss), and there is no people in very severe memory loss among elderly.

This study was supported by Chips . J Pillai., et al (2009), conducted a early assessment of memory impairment in people over 65 years old . Tests used for the early diagnosis with memory loss are Wechsler memory scale. They recorded 74. 5 % of memory complaints for old age people. Memory consultations were assessed at clinical settings and improve the access to early medical and behavioral support.

Among 60 samples 3(5%) of them scored between 21-25 (Mild cognitive impairment), 56 (93. 33%) of them scored between 11- 20 (Moderate cognitive impairment), 1 (1. 66%) of them scored between 0-10 (Severe cognitive impairment) among elderly.

This study was supported by Cynthia Thomas et al ( 2005 ) , conducted the study on cognitive assessment for elderly ; A brief screening test for mild cognitive impairment. Mini mental status examination administered to all the participants. 94 Participants meeting mild cognitive impairment clinical criteria. The study concluded that 55%people detect mild cognitive impairment.

2) The second objective of the study was association between the memory loss with demographic variables:

The chi square value for the association of age and memory loss among elderly is significant 0. 001 levels. Hence, a significant association between age and memory loss.

There is no significant association between memory loss with sex , education , occupation before coming to the old age home , marital status , income before coming to the old age home , duration of stay in the old age home , family history of mental illness , source of income among elderly.

This study was supported by Gary . J Kennedy (2008), assessed the age associated memory impairment. 160 participants were selected with the age group of 70 -80 years. Used 4 computerized & 3 non computerized memory tests. The participants score was low on two memory test. The data suggest that 80 % subjects had memory impairment.

3) The third objective was to associate the cognitive impairment with demographic variables.

There is no significant association between cognitive impairment with demographic variables such as age , sex , education , occupation before coming to the old age home , marital status , income before coming to the old age home , duration of stay in the old age home , family history of mental illness , and source of income among elderly.

This study was supported by John . M Starr et al (1999) conducted a study on age associated cognitive decline in healthy older people. Results were the study fails to support the hypothesis that cognitive decline can be attributed to age alone in healthy older people. They detected 57% older people had moderate cognitive impairment.

4) The fourth objective was to assess the correlation between memory loss and cognitive impairment.

Mean value for memory loss is 38. 3 and standard deviation value is 5. 60, and mean value for cognitive impairment is 15. 5 and standard deviation value is 2. 89. Correlation of memory loss and cognitive impairment score is 0. 407. It is evident that there is a positive correlation between memory loss and cognitive impairment among elderly.

This study was supported by Noboru Habu., et al (2010). Conducted a cross sectional study on relationship between mild memory impairment and cognitive impairment. Results were the study there is a correlation of coefficient of memory loss and cognitive impairment(r = 0. 391). There is a positive correlation between memory loss and cognitive impairment among elderly.

SUMMARY

The present study aimed to assess the memory loss and cognitive impairment among elderly at ST. JOSEPH old age home in Coimbatore.

The objectives were to:

1) Assess the memory loss and cognitive impairment among elderly.

2) Associate the memory loss with demographic variables among elderly

3) Associate the cognitive impairment with demographic variables among elderly.

4) Correlate the memory loss and cognitive impairment among elderly.

Review of literature facilitated the investigator to collect the relevant information to support the study. The researcher adopted descriptive research design for conducting this study. The conceptual frame work was based on Modified bio psychosocial model 1999. The researcher to identify the memory loss and cognitive impairment among elderly. 60 elderly were selected by convenient sampling technique . The tool used for data collection consists of Wechsler memory scale, mini mental status examination.

The data was collected for a period of 6 weeks in ST. JOSEPH OLD AGE HOME Coimbatore. Based on the objectives, data were analyzed using both descriptive and inferential statistics.

MAJOR FINDINGS OF THE STUDY:

• According to statistical analysis, 1(1. 66%) elderly had mild memory loss.
• 19(31. 66%) elderly had moderate memory loss.
• 40(66. 66%) elderly had severe memory loss.
• 3(5%) elderly had mild cognitive impairment.
• 56(93. 33%) elderly had moderate cognitive impairment.
• 1(1. 66%) elderly had severe cognitive impairment.
• Chi square value for the association of age with memory loss is significant at 0. 001 levels. So these findings indicated that as age progress the memory will get decreased.
• Chi square value for the association of cognitive impairment with demographic variables is not significant.
• Mean value for memory loss is 38. 3 and standard deviation is 5. 60.
• Mean value for cognitive impairment is 15. 5 and standard deviation is 2. 89.
• The findings indicated that the Correlation value of memory loss and cognitive impairment is 0. 407. It was evident that there is positive correlation between memory loss and cognitive impairment. It can be assumed when memory loss get increased the cognitive impairment also will increase.

CONCLUSION:

That it is concluded that elderly are suffers from memory loss and cognitive impairment, there is a significant association between age and memory loss. As the age progress the memory will get decreased. And there is no significant association between cognitive impairment with demographic variables. There is a positive correlation between memory loss and cognitive impairment among elderly.
