Registry of Chronic Subdural Hematoma

The goal of this observational study is to better understand how chronic subdural hematoma (CSDH) progresses and how patients are treated and cared for. The study focuses on three main questions: 1. What are the characteristics of patients with CSDH when they are diagnosed? 2. What treatments do patients with CSDH receive? 3. What are the outcomes for patients with CSDH, including their functional ability, cognitive health, and neurological status? Participants will receive their usual standard treatment. As part of the study, they will complete a brief telephone interview three months after their treatment.
