Insights
Newly diagnosed hypertensive patients show early signs of cognitive decline and increased anxiety. Early intervention is crucial to prevent further cognitive impairment and manage cardiovascular changes associated with high blood pressure.
Area of Science:
- Cardiovascular research
- Neuroscience
- Hypertension studies
Background:
- Hypertension is a known risk factor for cognitive decline.
- Individuals with high blood pressure exhibit higher risks of mild cognitive deterioration compared to normotensive individuals.
- This study investigates cardio- and cerebrovascular reactivity and cognitive performance in newly diagnosed hypertensive patients.
Purpose of the Study:
- To assess cognitive performance in newly diagnosed hypertensive patients.
- To evaluate cardio- and cerebrovascular reactivity in hypertensive individuals.
- To identify early manifestations of hypertension's impact on cognitive function and cardiovascular parameters.
Main Methods:
- Eighty-one newly diagnosed hypertensive patients were compared with 94 healthy controls.
- Cardiovascular and cerebral hemodynamic parameters were monitored during head-up tilt table testing (HUTT).
- Neuropsychological tests assessed reaction time, memory, attention, anxiety, and depression.
Main Results:
- Hypertensive patients exhibited significant differences in cardiovascular parameters (blood pressure, total peripheral resistance index, stroke index) but not in cerebral blood flow velocity during HUTT.
- While reaction time did not differ, short-term memory (Digit Span Test) was significantly impaired in hypertensive patients.
- Hypertensive patients showed lower overall cognitive test scores and increased anxiety levels compared to controls.
Conclusions:
- Reduced neuropsychological performance and altered cardiovascular parameters are early indicators of hypertension.
- Early detection and intervention are vital for managing hypertension and preventing cognitive decline.
- This research highlights the importance of monitoring cognitive function in hypertensive patients.
Background:
Hypertensive (HT) patients are at higher risk of cognitive decline than normotensive individuals, because high blood pressure is a risk factor for mild cognitive deterioration. In this study cardio- and cerebrovascular reactivity along with cognitive performance was assessed on newly diagnosed HT patients.
Methods:
Diagnosis of hypertension was based on international recommendations. None of the patients had diabetes, and all of them had normal cerebral CT scan. Eighty-one patients (43.5±10.2 years, male/female ratio: 42/39) were compared with 94 healthy controls (44±9.4 years, male/female ratio: 50/44). In both groups continuous, non-invasive and simultaneous monitoring of cerebral and cardiac hemodynamical parameters were recorded during head-up tilt table testing (HUTT). Reaction time, attention and memory skills, anxiety and depression rate were determined by neuropsychological tests.
Results:
During HUTT significant differences were found in certain cardiovascular parameters (blood pressure, total peripheral resistance index, stroke index), but no differences were detected in cerebral blood flow velocity. While there was no significant difference in reaction time between the two groups, tests estimating short-term memory (Digit Span Test) differed significantly. Moreover, sum of standardized test scores was significantly lower, while anxiety level was significantly increased in HT patients compared to controls.
Conclusion:
Decrease in neuropsychological performance along with alterations of cardiovascular parameters is an early manifestation of hypertension. Aim for an early intervention and accurate treatment is crucial for preventing further impairments.
