Dynamics of Cognitive Impairment in MCI Patients over a Three-Year Period: The Informative Role of Blood Biomarkers, Neuroimaging, and Genetic Factors.

Given the high growth rates of cognitive decline among the elderly population and the lack of effective etiological treatments, early diagnosis of cognitive impairment progression is an imperative task for modern science and medicine. It is of particular interest to identify predictors of an unfavorable subsequent course of cognitive disorders, specifically, rapid progression. Our study assessed the informative role of various risk factors on the dynamics of cognitive impairment among mild cognitive impairment (MCI) patients.

[Cognitive and emotional disorders in neurosurgical patients and their impact on postoperative rehabilitation].

Objective: To evaluate the severity of emotional and cognitive disorders, as well as the effectiveness of cognitive-motor training in patients who have undergone spinal cord surgery.

Materials And Methods: Sixty patients (30 men and 30 women), who were scheduled and subsequently underwent spinal cord surgery, were studied. The patients underwent clinical, somatic and neurological status examinations and quantitative neuropsychological testing.

Impact of atrial fibrillation on the rate of mild cognitive impairment in the elderly.

Mild cognitive impairment (MCI) in patients with cardiovascular risks is a transitional state to vascular dementia but which still has a possibility of being managed. The objectives of this study were to assess the impact of atrial fibrillation (AF) on cognitive performances in the elderly in comparison with similar cardiovascular risks. One hundred unselected patients were included in AF+ and AF- groups.

Comparative analysis of cognitive impairments in lewy body dementia and Alzheimer's disease.

Neuropsychological studies of 50 patients with Lewy body dementia (LBD) and 50 patients with Alzheimer's disease (AD) were performed to assess the characteristics of the cognitive impairments in these diseases. In patients with dementias of similar severities, patients with LBD showed greater impairment of executive and visuospatial functions and had more marked neurodynamic dysfunction. Patients with AD showed more profound memory disorders.

Differences in age at onset and familial aggregation between clinical types of idiopathic Parkinson's disease.

Idiopathic Parkinson's disease (PD) can be subdivided by its patterns of motor symptoms into tremor-dominant (TDT), akinetic-rigid (ART), and mixed type (MT). Our objective was to determine whether age at onset and family history are different in these three types. In total, 366 patients with PD were assigned in a standardized approach to one of the three subtypes.
