In Search Of Psychiatric Kinds: Natural Kinds And Natural Classification In Psychiatry, Nicholas Slothouber
In Search Of Psychiatric Kinds: Natural Kinds And Natural Classification In Psychiatry, Nicholas Slothouber
Electronic Thesis and Dissertation Repository
In recent years both philosophers and scientists have asked whether or not our current kinds of mental disorder—e.g., schizophrenia, depression, bipolar disorder—are natural kinds; and, moreover, whether or not the search for natural kinds of mental disorder is a realistic desideratum for psychiatry. In this dissertation I clarify the sense in which a kind can be said to be “natural” or “real” and argue that, despite a few notable exceptions, kinds of mental disorder cannot be considered natural kinds. Furthermore, I contend that psychopathological phenomena do not cluster together into kinds in the way that paradigmatic natural kinds (e.g., chemical …
Using Meditation To Improve Measures Of Attention In Older Adults, Sabrina Ford
Using Meditation To Improve Measures Of Attention In Older Adults, Sabrina Ford
Electronic Thesis and Dissertation Repository
Age-related cognitive decline greatly impacts quality of life for older adults. Previous research has indicated that meditation may act as a neuroprotective factor to prevent age-related cognitive decline. This thesis sought to replicate previous findings and investigate if a four-week meditation intervention would improve sustained attention. Participants 60 years and older (n=27, 17 female) were recruited and assigned to a focused-attention (FA) meditation or relaxation group which met for four weeks, three times a week. Resting-state EEG was used to collect individual alpha peak frequency (iAPF) and frontal alpha asymmetry (FAA). The Sustained Attention to Response Task (SART) was also …
Off-Label Use Of Second Generation Antipsychotics In Primary Care -An Exploratory Study, Nima Gheisarzadeh
Off-Label Use Of Second Generation Antipsychotics In Primary Care -An Exploratory Study, Nima Gheisarzadeh
Electronic Thesis and Dissertation Repository
Over the past two decades, the use of antipsychotics has increased tremendously worldwide, and second-generation antipsychotics (SGAs) have been the main driver of this trend. The extensive use of SGAs for off-label purposes has raised concerns over their role in clinical practice. In particular, studies have revealed serious metabolic and cardiovascular effects, and evidence is lacking on SGAs’ effectiveness. Despite the concerns, the extent and pattern of SGAs’ off-label use is largely unknown within the context of the Canadian primary health care system. Using electronic medical record (EMR) data from 14 practices in southwestern Ontario, we investigated the number of …
Investigating The Relationship Between Subcortical And Cortical Auditory Processing, Sonia Varma
Investigating The Relationship Between Subcortical And Cortical Auditory Processing, Sonia Varma
Electronic Thesis and Dissertation Repository
The auditory system is highly integrative, with feedforward and feedback connections from periphery to cortex (and stages in between). In order to understand how the different levels of the human auditory system interact, it is necessary to simultaneously measure responses from multiple auditory levels. A novel stimulus was paired with electroencephalography (EEG) in 29 young, normal-hearing participants (17-34 years) to examine interactions among stages of the auditory pathway. Temporal regularity was manipulated by continuously accelerating and decelerating the rate of a click-train stimulus (i.e., ~3.5 Hz frequency modulation of the click rate). Adaptation of the brainstem (cochlear nucleus and inferior …
Prevalence Of Moral Injury In Canadian Forces Members Deployed To Afghanistan, Kevin T. Hansen
Prevalence Of Moral Injury In Canadian Forces Members Deployed To Afghanistan, Kevin T. Hansen
Electronic Thesis and Dissertation Repository
Moral injury is a relatively new area of study within military mental health care, as such, prevalence estimates for both moral injury and exposure to potentially morally injurious events (PMIE; a moral injury precursor) are unknown for many of the world’s militaries. PMIE is commonly defined as the perpetrating, failing to prevent, witnessing, or learning about acts or events that transgress an individual’s deeply held moral belief(s). The primary purpose of this study was to estimate the prevalence of PMIE in a population of Canadian Armed Forces (CF) members who served in support of the recent mission to Afghanistan. How …
The Association Between Child And Youth Mental Health Service Urgency And Exposure To Childhood Interpersonal Trauma, Catherine Marshall
The Association Between Child And Youth Mental Health Service Urgency And Exposure To Childhood Interpersonal Trauma, Catherine Marshall
Electronic Thesis and Dissertation Repository
Children/youth with a history of maltreatment experience a variety of different developmental, psychiatric and health problems and ensuring there is streamline access to services is imperative to their recovery. Yet, there are few reports of standardized methods for directing and prioritizing risk for children seeking services. The current study,utilizingretrospective data collected from theinterRAIChild and Youth Mental Health Screener (ChYMH-S), aimed to address this gap and explore the relationship between childhood maltreatment and mental health screening outcomes. A sample of 4-18-year-olds (N= 19,645) was studied to explore how differences in maltreatment history, gender, and legal guardianship impacted service prioritization. The findings …
