RESUMO

OBJECTIVE: To study the efficiency of the neuropsychological rehabilitation of patients with mild cognitive impairments. MATERIAL AND METHODS: The study included 103 elderly people, aged 59 to 88 years, including 90 women and 13 men with subjective complaints of memory loss (ICD-10: F06.70; F06.71; F06.78; F06.79). Participants were divided into experimental group (n=43) and comparison group (n=42). The estimated impact was the rehabilitation program «The psychosocial therapy and neurocognitive rehabilitation of elderly patients with cognitive impairments¼, within which the principle of complex stimulation of various parameters of the cognitive sphere was used in rehabilitation work with patients in the experimental group in accordance with the «Memory Clinic¼ program. The study was conducted using randomized, equalized comparison groups, and the principle of «triple-blind¼ research. Non-parametric statistics (SPSS) methods were used to assess differences. RESULTS: A significant difference between the comparison and experimental groups has been identified, primarily in relation to high-level mental processes associated with the function of the third structural-functional block according to A.R. Luria. After the training, the number of correct answers significantly increased (t(42)=-2.67, p<0.001) in the experimental group, while in the comparison group the indicator did not change (t(41)=0.50, p=0.617). The number of false alarms in the experimental group decreased significantly (t(42)=2.13, p=0.039). CONCLUSION: The results confirm the leading role of these processes in the hierarchy of mental functions, which suggests that they should primarily be targets of rehabilitation interventions.

RESUMO

OBJECTIVE: To compare the content of ß-amyloid (Aß) peptides Aß40, Aß42, total and threonine phosphorylated 181 tau-protein in cerebrospinal fluid (CSF) of patients with the clinical diagnosis of Alzheimer's disease (AD). MATERIAL AND METHODS: The study was performed on 64 patients with a diagnosis of dementia and MMSE scores of 24 or lower. All patients underwent lumbar puncture. Aß40, Aß42, Aß42/40 ratio, total tau, phosphorylated tau at threonine 181 were determined in the CSF using a multiplex assay according to the manufacturer's protocol, the concentration was determined in pkg/ml. RESULTS: The preliminary diagnosis of AD was made in 3 patients (5%). As a result of the study of protein content in the CSF, signs of AD were detected in 48 (75%) people. The findings suggest that the diagnosis of AD is made 10-14 times less frequently than it should be according to the World Health Organization data. The discrepancy between clinical diagnosis and laboratory findings is confirmed by our study. CONCLUSION: Differences in the therapy of dementias and the development of new drugs targeting specific links in the pathogenesis of different types of dementias require accurate and complete diagnosis of dementias, especially AD, as the most common type of dementia.
