- Journal of Vegetation Science published by John Wiley & Sons Ltd on behalf of International Association for Vegetation Science.Aims: Understanding fine-grain diversity patterns across large spatial extents is fundamental for macroecological research and biodiversity conservation. Using the GrassPlot database, we provide benchmarks of fine-grain richness values of Palaearctic open habitats for vascular plants, bryophytes, lichens and complete vegetation (i.e., the sum of the former three groups). Location: Palaearctic biogeographic realm. Methods: We used 126,524 plots of eight standard grain sizes from the GrassPlot database: 0.0001, 0.001, 0.01, 0.1, 1, 10, 100 and 1,000 m2 and calculated the mean richness and standard deviations, as well as maximum, minimum, median, and first and third quartiles for each combination of grain size, taxonomic group, biome, region, vegetation type and phytosociological class. Results: Patterns of plant diversity in vegetation types and biomes differ across grain sizes and taxonomic groups. Overall, secondary (mostly semi-natural) grasslands and natural grasslands are the richest vegetation type. The open-access file ”GrassPlot Diversity Benchmarks” and the web tool “GrassPlot Diversity Explorer” are now available online (https://edgg.org/databases/GrasslandDiversityExplorer) and provide more insights into species richness patterns in the Palaearctic open habitats. Conclusions: The GrassPlot Diversity Benchmarks provide high-quality data on species richness in open habitat types across the Palaearctic. These benchmark data can be used in vegetation ecology, macroecology, biodiversity conservation and data quality checking. While the amount of data in the underlying GrassPlot database and their spatial coverage are smaller than in other extensive vegetation-plot databases, species recordings in GrassPlot are on average more complete, making it a valuable complementary data source in macroecology. © 2021 The Authors.

- Objective: To examine whether there were any differences in recovery in performance of personal activities of daily living (P-ADL) in relation to cognitive impairments pre- and poststroke from discharge to 6 and 12 months in elderly persons. Methods: Forty-five elderly persons after stroke were assessed at discharge from the hospital at 6 and at 12 months. A questionnaire was used to evaluate the person´s prestroke cognitive status. P-ADL was assessed with the Barthel Index. The Mini Mental State Examination and neuropsychological tests were used to measure cognitive functions. Results: Persons with cognitive impairments before and after stroke did not improve in P-ADL from the acute phase until 6 and 12 months, while persons with intact cognition pre- and poststroke did. Conclusion: Since cognitive problems pre- and poststroke hinder recovery in P-ADL, it is important to be aware of the connection between cognitive impairment and activity limitations in planning the optimal rehabilitation. Key words: ADL, cognitive dysfunction, elderly, longitudinal, prestroke, stroke

- Abstract Objective: To examine whether there were any differences in the recovery in performance of personal activities of daily living (P-ADL) in elderly persons in relation to cognitive impairments pre- and poststroke from discharge to 6 and 12 months in elderly persons. Methods: Forty-five elderly persons after stroke were assessed at discharge from hospital and at 6 and at 12 months after stroke onset. A questionnaire posed to the next of kin was used to evaluate the person´s pre- and poststroke cognitive status. P-ADL was assessed with the Barthel Index. The Mini Mental State Examination and neuropsychological tests were used to measure cognitive functions after stroke. The National Institute of Health Stroke Scale was used to measure neurological deficits. Results: Persons with cognitive impairments before and after stroke did not improve in P-ADL from the acute phase until 6 and 12 months, while persons with intact cognition pre- and post stroke did. Conclusion: Since cognitive problems pre- and poststroke hinder recovery in P-ADL, it is important to understand the connection between cognitive impairment and activity limitations when planning the optimal rehabilitation, which could include special compensation strategies, learnt by the patients, cognitive assistive devices and/or appropriate personal support trained in meaningful activities in daily life in their natural environment.

- Objectives We examined cognitive functions before and in acute phase of stroke studying frequency and profile of cognitive impairment and relationships between cognitive status.MethodsSeventy-four patients with early phase after stroke and 49 healthy controls were included and examined using the Mini-Mental State Examination (MMSE) and a battery of neuropsychological tests. Cognitive status before stroke-onset was investigated using Cognitive Impairment Questionnaire.ResultsCognitive impairments were present in 96% of patients after stroke onset using the battery of neuropsychological tests and in 39% of patients using the MMSE, but in only 9% of controls. Seventy-six percent exhibited reduced executive function and 75% reduced psychomotor tempo. Cognitive dysfunction was present in 52% before stroke onset without any impact on the frequency of impairment in the various cognitive areas in early phase after stroke.ConclusionsCognitive impairment is frequent before the onset of stroke among older people and may partially explain the very high frequency of cognitive impairment observed after stroke onset.
