Attitude to the disease and quality of life in elderly patients with mild vascular dementia after the novel coronavirus infection

In order to study the types of attitude towards the disease and quality of life (QoL) in elderly patients with mild vascular dementia (MVD) living in the conditions of the psychoneurological institution Social Service House “Severnoye Izmailovo” in Moscow, there were 2 study groups: the patients with the clinical debut of the novel coronavirus infection (NCVI) of 6 months +/– 1 month with the recovery outcome (n=65; 33 men, 32 women) and those who did not have COVID-19 (hospital control group; n=67; 34 men, 33 women). The mean age of the studied patients was 73.05±3.48 years. The age and sex composition of the two groups was homogeneous (p>0.05). Emotional disorders were investigated using the Cornell Scale for Depression in Dementia (CSDD); cognitive disorders – by means of the Montreal Cognitive Assessment (MoCA); QoL – by the Quality of Life in Alzheimer's Disease scale (QoL-AD): QoL self-assessment (QoL-AD-SR (self-rating)) and proxy QoL rating (QoL-AD-PR (proxy rating)); the type of attitude towards the disease – by the TATD scale (Wasserman L.I. et al., 2005). It was found that COVID-19 aggravates cognitive deficits in patients with MVD (according to MoCA 20.80±0.59 /21.40±0.78 points; p<0.05) in the absence of depression (according to CSDD 1.52±0.50 / 1.52±0.84 points in the group of the patients after NCVI / hospital control group, respectively; p>0.05). In the patients after COVID-19, a correlation was found between the proxy QoL rating and the severity of cognitive dysfunction according to the MoCA (R= – 0.28), while in the hospital control group – between the proxy QoL rating and the severity of depressive manifestations (R= – 0.33). The first group of the patients was characterized by a mixed type of attitude to the disease and intrapsychic maladaptation (the neurasthenic type ranked first at 16.03±8.29 / 9.34±5.03 points), while the second group had a diffuse type of attitude to the disease and interpsychic maladaptation (the sensitive type ranked first at 10.31±5.71 / 14.90±7.62 points by the TATD scale among the elderly patients with MVD who have / have not undergone NCVI; p<0.05). The revealed patterns can contribute to the optimization of personalized models of medical and psychological rehabilitation of elderly patients with MVD living in closed-type care facilities.
