INTRODUCTION: The issue of resistance to antiplatelet therapy has raised many questions in the area of neurovascular diseases. The first objective of this work was to determine the prevalence of aspirin resistance in neurovascular patients with clinical non-responsiveness to aspirin treatment and a high-risk of atherothrombotic complications using two interpretable and independent methods (aggregation and PFA 100). The second objective was to find the correlation between both assays and to evaluate the results in groups at risk for various cerebrovascular diseases. MATERIAL AND METHODS: Laboratory tests of aspirin resistance were performed in 79 patients with clinical non-responsiveness to aspirin treatment suffering from neurovascular diseases. Patients were divided into the two groups: expected low risk for aspirin resistance due to the first manifestation of a neurovascular disease (n = 34) and expected high risk due to the second clinical manifestation of a neurovascular disease (n = 45). RESULTS: The prevalence of aspirin resistance in both groups combined as determined by the PFA-100 and CPG techniques were 50.6% and 17.7%, respectively. No correlation was found between the two techniques. CONCLUSIONS: No significant prevalence of aspirin resistance was demonstrated by either method despite the heterogeneous pathophysiological mechanisms. However, we are presently unable to provide an accurate opinion on the value of laboratory test result or routine monitoring in clinical neurology. and M. Vališ, D. Krajíčková, J. Malý, R. Malý, I.

U pacientů s demencí se kromě narušení kognitivních funkcí ve velké míře vyskytují behaviorální a psychologické příznaky. Mohou mít formu úzkosti, deprese a nespavosti, ale také neklidu, bloudění a agresivního chování a výjimkou není ani přítomnost psychotických příznaků. Tyto nekognitivní projevy demence se v určité fázi nemoci objeví až u 90 % pacientů a představují velkou zátěž jak pro pacienty samotné, tak pro jejich rodiny a pečovatele. Nalezení účinné a bezpečné léčby behaviorálních a psychologických příznaků demence je velmi obtížné, protože chybí dostatek kvalitních studií a mnoho dostupných léků je spojováno se závažnými nežádoucími účinky. Článek v přehledu uvádí aktuální nefarmakologické a farmakologické možnosti léčby zmíněných příznaků a zaměřuje se na využití antipsychotik v této indikaci. Jsou prezentována data o účinnosti, nežádoucích účincích a bezpečnosti jednotlivých preparátů, ale také praktické informace ohledně vedení léčby, dostupnosti léků a dávkování., Apart from cognitive decline, patients with dementia suffer a great deal from so called behavioural and psychological symptoms. These symptoms may appear in a form of anxiety, depression and insomnia as well as agitation, wandering and aggressive behaviour. Also, the presence of psychotic symptoms is not rare. These non‑cognitive symptoms of dementia occur at some stage of the illness in up to 90% of patients and, as such, they pose a great burden not only on patients themselves but also on their caregivers. Finding an effective and safe management of behavioural and psychological symptoms of dementia is very difficult as properly conducted studies are lacking and many available agents are associated with serious adverse effects. The article briefly summarizes current non‑pharmacological and pharmacological options for the treatment of the above described symptoms and focuses on the use of antipsychotic drugs in this indication. We present data on efficacy, adverse effects and safety of individual agents as well as practical information including drug availability and dosing strategies. Key words: dementia – behavioural and psychological symptoms – antipsychotics – efficacy – mortality The authors declare they have no potential conflicts of interest concerning drugs, products, or services used in the study.
