Identifying and controlling risk factors for cognitive decline is crucial for preserving cognitive function.</p> <p><bold>AIM:</bold> To assess the association of hyperuricemia and type 2 diabetes mellitus (T2DM) with cognitive functions, evaluated using parameters of the auditory event-related P300 potential in elderly individuals with controlled arterial hypertension (AH).</p> <p><bold>MATERIALS AND METHODS:</bold> A cohort of individuals aged 60–74 years was examined. Four groups were formed: Group I (control), without cardiovascular diseases or diabetes, and with normal uric acid levels (<italic>n</italic>=42); Group II, with controlled AH (<italic>n</italic>=87); Group III, with controlled AH and T2DM (<italic>n</italic>=34); and Group IV, with controlled AH and hyperuricemia (<italic>n</italic>=17). The parameters of the auditory event-related P300 potential were assessed using an electroencephalograph (Neuron-Spectrum-4/VPM, Russia).</p> <p><bold>RESULTS:</bold> No statistically significant differences in P300 latency and amplitude were found in older individuals with controlled AH compared to the control group. In the group with T2DM and controlled AH, an increase in P300 latency and a decrease in amplitude were observed compared to the control group. In the group with hyperuricemia and controlled AH, a lower P300 amplitude was detected compared to the control group.</p> <p><bold>CONCLUSION:</bold> Older individuals with hyperuricemia and controlled AH exhibited a lower P300 amplitude, indicating reduced attentional resources. Those with controlled AH and T2DM showed increased P300 latency and decreased amplitude, reflecting slower information processing, prolonged decision-making time, and diminished attentional resources.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold><bold> </bold>В мире число людей с деменцией и когнитивными нарушениями постоянно увеличивается.

У пожилых людей с контролируемой артериальной гипертензией и сахарным диабетом 2-го типа наблюдалось увеличение латентности и снижение амплитуды Р300, что отражает снижение скорости обработки информации и увеличение времени принятия решений, а также снижение ресурсов внимания.</p></trans-abstract><trans-abstract xml:lang="zh"><p>背景。全球范围内痴呆和认知障碍患者数量持续增加。识别和控制认知功能下降的风险因素对于保持认知功能至关重要。</p> <p>研究目的。评估高尿酸血症和2型糖尿病对老年高血压患者认知功能的影响，并基于听觉事件相关 P300 电位参数进行认知功能评估。</p> <p>材料与方法。研究对象为60–74 岁的老年人，按照病情分为四组：I 组（对照组）— 无心血管疾病、无糖尿病，且尿酸水平正常（n=42）；II 组 — 控制性高血压（n=87）； III 组 — 控制性高血压合并2型糖尿病（n=34）；IV 组 —控制性高血压合并高尿酸血症（n=17）。通过脑电图仪（Neuron-Spectrum-4/VPM, 俄罗斯）测量听觉事件相关 P300 电位的参数，包括P300 潜伏期和振幅。</p> <p>结果。控制性高血压患者（II 组）的 P300 潜伏期和振幅与对照组相比无统计学显著差异。合并 2型糖尿病（III 组）的患者 P300 潜伏期显著延长，振幅降低。合并高尿酸血症（IV 组）的患者 P300 振幅显著低于对照组。</p> <p>结论。合并高尿酸血症的老年高血压患者的P300 振幅降低，提示注意力资源减少。合并 2型糖尿病的患者的P300 潜伏期延长，振幅降低，反映出信息处理速度下降、决策时间延长及注意力资源减少。</p></trans-abstract><kwd-group xml:lang="en"><kwd>hypertension</kwd><kwd>hyperuricemia</kwd><kwd>type 2 diabetes mellitus</kwd><kwd>cognitive dysfunction</kwd><kwd>event-related potentials</kwd><kwd>aged</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>артериальная гипертензия</kwd><kwd>гиперурикемия</kwd><kwd>сахарный диабет 2-го типа</kwd><kwd>когнитивная дисфункция</kwd><kwd>вызванные потенциалы, связанные с событием</kwd><kwd>пожилые люди</kwd></kwd-group><kwd-group xml:lang="zh"><kwd>高血压</kwd><kwd>高尿酸血症</kwd><kwd>2型糖尿病</kwd><kwd>认知功能障碍</kwd><kwd>事件相关电位</kwd><kwd>老年人</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Российский научный фонд</institution></institution-wrap><institution-wrap><institution xml:lang="en">Russian Science Foundation</institution></institution-wrap><institution-wrap><institution xml:lang="zh">Russian Science Foundation</institution></institution-wrap></funding-source><award-id>23-15-20017</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Zueva IB, Krivonosov DS, Buch AV.
