Cognitive Dysfunction in Chronic and Persistent Immune Thrombocytopenia
Trial Parameters
Brief Summary
Individuals with immune thrombocytopenia (ITP) frequently report difficulties with attention and memory. The main question this study seeks to answer is: Do patients with ITP have evidence of cognitive impairment as detected by a cognitive function test battery? To address this issue, participants will take a cognitive function test and complete surveys on quality of life, fatigue, depression, and cognitive symptoms. The primary aim of the study is to evaluate for the presence and extent of cognitive impairment in patients with ITP. The study will also assess whether cognitive impairment in ITP is associated with patient-reported impacts on quality of life, fatigue, mood, and cognitive symptoms as well as clinical characteristics such as ITP disease and treatment history.
