The norms obtained will be extremely useful in the clinical evaluation of young Spanish adults.

As part of the NEURONORMA project, we provide age- and education-adjusted norms for the Stroop color-word interference test (SCWT)-Golden version and the Tower of London-Drexel University version (TOL(DX)). The sample consists of 344 and 347 participants, respectively, who are cognitively normal, community dwelling, and ranging in age from 50 to 90 years. Tables are provided to convert raw scores to age-adjusted scaled scores. These were further converted into education-adjusted scaled scores by applying regression-based adjustments. Demographic variables, age, and education significantly affect scores of the SWCT and TOL(DX), sex, however, was found to be unrelated to performance in this sample. The normative data presented here were obtained from the same study sample as all the other NEURONORMA tests. In addition, the same statistical procedures for data analyses were applied. These co-normed data allow clinicians to compare scores from one test with all tests.

The data obtained will be useful in the clinical evaluation of young Spanish adults.

The cerebellum has been implicated in higher-order behavior. Blood flow studies (SPECT) have shown that cerebral diaschisis can appear after cerebellar lesions and this phenomenon could serve as a basis for a potential neuropsychological derangement after cerebellar insults. Our objectives in this study were to delineate the neuropsychological profile after cerebellar stroke, to evaluate cerebral diaschisis as measured by SPECT and to correlate the findings. We prospectively studied 26 patients with cerebellar stroke and 16 subjects matched for age, sex and educational level as a control group. A neuropsychological battery test, MRI and cerebral SPECT were performed in both groups. We found that cerebellar stroke results in motor control impairment and mild naming deficit, whereas no dysfunction in declarative memory, language, visuospatial or executive abilities is evident. The anatomical distribution of the lesion does not seem relevant in terms of neuropsychological impairment or diaschisis. Both ipsilateral and contralateral diaschisis as a result of a cerebellar stroke are found, but this phenomenon does not seem to result in overt neuropsychological derangement.

Background COVID-19 forced the implementation of restrictive measures in Spain, such as lockdown, home confinement, social distancing, and isolation. It is necessary to study whether limited access to basic services and decreased family and social support could have deleterious effects on cognition, quality of life, and mental health in vulnerable older people. Objective This study aims to explore the impact of the COVID-19 outbreak on cognition in older adults with mild cognitive impairment or dementia as the main outcome and the quality of life, perceived health status, and depression as secondary outcomes and to analyze the association of living alone and a change in living arrangements with those outcomes and other variables related with the use of technology and health services. Likewise, this study aims to analyze the association of high and low technophilia with those variables, to explore the access and use of health care and social support services, and, finally, to explore the informative-, cognitive-, entertainment-, and socialization-related uses of information and communications technologies (ICTs) during the COVID-19 outbreak. Methods This cohort study was conducted in Málaga (Spain). In total, 151 participants with mild cognitive impairment or mild dementia, from the SMART4MD (n=75, 49.7%) and TV-AssistDem (n=76, 50.3%) randomized clinical trials, were interviewed by telephone between May 11 and June 26, 2020. All participants had undergone 1-3 assessments (in 6-month intervals) on cognition, quality of life, and mood prior to the COVID-19 breakout. Results The outbreak did not significantly impact the cognition, quality of life, and mood of our study population when making comparisons with baseline assessments prior to the outbreak. Perceived stress was reported as moderate during the outbreak. After correction for multiple comparisons, living alone, a change in living arrangements, and technophilia were not associated with negative mental health outcomes. However, being alone was nominally associated with self-perceived fear and depression, and higher technophilia with better quality of life, less boredom, perceived stress and depression, and also less calmness. Overall, health care and social support service access and utilization were high. The most used ICTs during the COVID-19 outbreak were the television for informative, cognitive, and entertainment-related uses and the smartphone for socialization. Conclusions Our findings show that the first months of the outbreak did not significantly impact the cognition, quality of life, perceived health status, and depression of our study population when making comparisons with baseline assessments prior to the outbreak. Living alone and low technophilia require further research to establish whether they are risk factors of mental health problems during lockdowns in vulnerable populations. Moreover, although ICTs have proven to be useful for informative-, cognitive-, entertainment-, and socialization-related uses during the pandemic, more evidence is needed to support these interventions.
