Mild Cognitive Impairment in Older Adults With and Without Depressive Symptom
Factors Differentiating Older Adults With Mild Cognitive Impairment and Depressive Symptoms From Those With Mild Cognitive Impairment Without Depressive Symptoms
This study will compare adults aged 65 years or older who have mild cognitive impairment, with and without depressive symptoms. The researchers plan to participants at University Medical Centre Maribor, with two equally sized groups. They will compare outcomes in several different cognitive domains (visuospatial abilities, emotional modulation, social cognition) and in DNA methylation of relevant regions (for BDNF, COMT, and SLC6A4 gene promoters).

Descripción detallada
This cross-sectional observational study will examine cognitive and epigenetic differences between older adults with mild cognitive impairment who have depressive symptoms and those who do not. Potential participants will be identified through the outpatient psychogeriatric, psychiatric, and neurology clinics and the inpatient geriatric psychiatry units at University Medical Centre Maribor. Participants will be aged 65 years or older, have cognitive screening results consistent with mild cognitive impairment, and provide written informed consent. The planned sample will include two equally sized groups of participants.
Participants will be classified according to the presence or absence of depressive symptoms at the initial assessment. Depressive symptoms will be reassessed early in the study to confirm group classification. Participants will receive the same standard of diagnostic assessment and treatment as patients who do not take part in the study.
The study will compare performance on tasks assessing visuospatial abilities, emotional modulation abilities and social cognition. The investigators hypothesize that participants with depressive symptoms will perform better on the visuospatial task and less well on the emotional capture and social cognition tasks than participants without depressive symptoms. Blood samples will be collected to compare DNA methylation in the promoter regions of BDNF, COMT, and SLC6A4 between the two groups.

The study population will consist of adults aged 65 years or older with cognitive screening results consistent with mild cognitive impairment. Potential participants will be identified at University Medical Centre Maribor through the outpatient psychogeriatric, psychiatric, and neurology clinics and the inpatient geriatric psychiatry units. The planned sample includes equal numbers of participants with depressive symptoms without depressive symptoms.
