The aim of this research project is to find connections between cognitive functions of old people, who are in-patients in a medical day centre, their subjective evaluation of health, and their psychological welfare.

The group of the respondents has been 100 patients of hospital Therapeutical, Cardiology and Neurological Departments, whose age varies from 60 to 93 years.

The researcher has applied the questionnaire of subjective health assessment, made by prof. A.Goštautas (1999), the mini questionnaire of cognitive state (MMSE), and the scale of psychological balance, certified by prof. N. Bradburno (1969).

The research data have been computed using the programme packet SPSS 13.00 (Statistic Package for Social Sciences).

Analysing the research data, the author has found out that cognitive abilities of the senior in-patients of the Day centre are interrelated with their age, education and family status.

The results of the investigation have also proved that assessment of cognitive functions is interrelated with subjective health assessment. The patients, who assess their health worse, have weaker cognitive abilities. Subjective health assessment of the Day centre in-patients is related with their education. The patients, who have higher education, treat their health better.

The researcher has found out that better cognitive abilities of the interviewed patients are connected with their better psychological state.

The elder people, who treat their psychical and emotional health as very good or good, feel themselves better psychologically than their peers, treating their health as moderate or bad.

Health assessment is interrelated with the occupation of elder people: these patients, who are less occupied, assess their health worse.
