Leading-edge Cognitive Disorders Research
This new book presents important recent research on cognitive disorders which are disturbances in the mental process related to thinking, reasoning, and judgement. They include delirium, dementia, and other cognitive disorders. Cognition includes the domains of attention, memory, language, gnosis, visuospatial function, praxis, and executive function, and is traditionally distinguished from the emotions or 'feelings'. Cognitive disorders may disturb one domain specifically, as in a selective impairment of memory (amnesia) or language (aphasia), or, more often, a combination of deficits, as in mental retardation and dementia.
Research on Cognition Disorders
Research on cognitive disorders is challenging due to the complexity of functions and numerous variables involved. The main purpose of this book is to effectively address the methodological issues and controversies in cognitive disorders research. First, it reviews the concept of human cognition as a complex activity involving interconnected mental and cerebral processes (its systemic structure), which represent the natural and social-cultural world by means of signs (its mediated, semiotic nature) and result from the internalization (or appropriation by the individual) of external actions and relations with things and persons (its cultural-historical origin). Subsequently, methodological issues are examined, including the use of the systemic and network approach in neuropsychological research, the concepts of single and double dissociation, single-case versus group studies, problems of brain-behavioral correlations using the lesion method and functional neuroimaging, the influence of task-relevant variables (confounders) related to the patient (e.g., age, education), to the lesion (size, etiology), and to the tests and testing conditions (ecological validity, examiner ́s experience). Finally, readers are given the fundamentals of statistics applied to biomedical and psychological research, with illustrative examples of how to calculate Z score, effect size, χ2 test, t test, Pearson ́s correlation coefficient, and simple linear regression. Methodological problems in current cognitive research on early multiple sclerosis, medial temporal lobe epilepsy, mild cognitive impairment and dementia are examined in detail.
The Paraphilias

Release Date: 2019-10-21
Of the thousands of papers and books about problematic sexual behaviors, most focus solely on sex crimes or so-called "hyper-sexuality" or "sexual addiction." Together, these publications present a grim and pessimistic prognosis for anyone who has unusual sexual interests of any type. This book challenges that view by providing a more informed and balanced review of what is known and what is not known about unconventional sexual interests. It is based on approximately thirty years of experience by the author concerning the assessment and treatment of paraphilias and unconventional sexual interests. The Paraphilias: Changing Suits in the Evolution of Sexual Interest Paradigms examines current and past perspectives concerning unconventional sexual interests associated with both criminal and non-criminal activities. Extensively referenced, it challenges the dogma that sexual interests are immutably determined during a single critical period and are thereafter unchangeable. The book provides extensive case histories and tables summarizing over 100 paraphilias and the latest research regarding them. It also reviews diagnostic criteria for the paraphilias. Analyses of current and past paradigms are presented together with new ways to understand, investigate, and provide meaningful and effective assistance to people with paraphilias. It is written for mental health clinicians and specialists in the fields of sexology and forensic psychiatry and psychology.
