“…However, all tests have their limitations, and there is no consensus concerning which test should be routinely used in the assessment of POCD [14]. Some tests are not specific enough or have a wide variation and are, therefore, not well suited to detect subtle changes in the cognitive performance of a patient [35]. To eliminate this problem, multiple tests are used to assess different domains of cognitive function, such as orientation, memory, executive functions, concentration, and mathematical functions.…”

Postoperative cognitive dysfunction (POCD) is a severe long-term complication after surgical procedures. POCD is mainly seen among geriatric patients. Hospitalization, extent of surgery, and systemic inflammatory response might contribute to POCD. The possible influence of the type of anesthesia is discussed. POCD is often not recognized; thus, incidence rates are likely to be underestimated (19-40%). POCD is associated with major consequences for the individual patient, e.g., delayed long-term recovery, reduced quality of life, and an increased mortality rate. Multiple risk factors have been identified over the last decade. However, the exact etiology is still unknown. This mini-review summarizes the recent developments concerning POCD prevention, diagnosis, and treatment.

Background:Hypertension on a long-term basis can cause target organ damage, especially the central nervous system, which can affect cognition. It is known that difference between simple and choice reaction time (RT) implies time required for cognition. Although delayed RTs indicate involvement of cognition, they cannot quantify how much time is required for cognition.Aim:Recording chronoscpic RT to quantify time required for cognition in hypertensives and compare them with controls.Subjects and Methods:This is a hospital-based case–control study conducted (August 2010 to January 2011) on 118 subjects attending an outpatient department using visual and whole body reaction timers having criteria of age and hypertensive condition, compared with an equal number of age- and sex-matched controls. Statistical analysis was carried out by Independent t test and duration of hypertension was correlated with whole body choice reaction time (WBCRT) C1 using Pearson's correlation. Predictive value of WBCRT C1 was calculated by using the receiver operating characteristic curve.Results:The WBCRT C1 562.6 (108) ms was more delayed among hypertensives compared with controls 523.5(98.8) ms. There was no significant correlation between duration of hypertension and WBCRT C1 (r = -0.064). The best cut-off value for WBCRT C1when predicting cognitive dysfunction in hypertensive patients was 538.5 ms (sensitivity 76.2%, specificity 50%).Conclusions:WBCRT C1 can be a quantitative measurement of cognition. It can be used as a screening tool to detect cognitive dysfunction.
