Dementia is associated with the gradual impairment of mental ability. The population of people suffering from dementia is as large as 50 million. Most dementia cases result from various neurodegenerative diseases (NDs) linked by a progressive degeneration of neurons. Among NDs, Alzheimer's disease (AD) is the most frequent cause of dementia and accounts for 60-80% of cases. Certain pathological changes on the cellular and subcellular level occur even 15 years before the manifestation of clinical symptoms of AD. This first asymptomatic phase of AD is considered a preclinical stage, whereas mild cognitive impairment (MCI) is the symptomatic pre-dementia stage. The third, fully symptomatic phase of AD is dementia due to AD. The presence of specific proteins in the cerebrospinal fluid (CSF) may be considered as a characteristic feature of some NDs. The measurement of their CSF concentrations, together with neuropsychological examination and neuroimaging, may be useful for diagnosing AD. The collection of CSF samples is performed by lumbar puncture, which is a medical procedure that requires obtaining informed consent from patients. While asymptomatic AD patients have full legal capacity, those with dementia require a legal guardian who will represent them. Thus, the objective of this study is to compare the legal systems regulating the legal capacity issue in the USA, U.K. (England and Wales), Germany, and Poland. These countries have been chosen as examples of three different types of legal orders, according to the sources of law, i.e., civil law, common law, and case law.
Since the beginning of the 1990s Poland has been developing a system of counteracting and fighting the money laundering phenomenon. Such actions were started because of the need to protect the Polish legal system and the Polish economy against the threat coming from organised criminal groups wanting to invest in Poland the proceeds derived from illicit activities. Poland is an attractive country to them as far as investing is concerned because of the great demand for capital needed to conduct the necessary transformations in the economic and social system.
. The aim of this study is to present the possibilities of using structured analytical techniques in building investigative versions. They may relate to ongoing criminal or operational proceedings, but also allow verification of versions created for the purposes of supervision or evaluation of other proceedings. In this area, the study complements and at the same time extends the existing knowledge in the field of forensic tactics. The author presented the current state of knowledge on the methods of building criminal versions and the theoretical justification for the introduction of these techniques to the practice of law enforcement agencies in this aspect. An outline of the methodology of the application of analytical techniques in the construction of new and verification of existing research methods is also presented. This study is based on the author’s speech at the 3rd National Scientific Conference entitled ‘Police X Files’ organised by the Faculty of Law and Administration University of Lodz from September 26th–28th, 2018.
