What the Research Shows Concerning Rapidly Resolving Acute Subdural Hematomas in TBI Patients

Subdural hematomas are caused by bleeding between the tissues around the brain. When blood vessels burst, or bleeding occurs after a traumatic brain injury, the resulting pressure on the brain can be fatal. It is estimated that around 12-30% of TBI patients experience acute subdural hematomas, and around 40-70% of those patients die from the condition. For those who survive, recovery usually takes a number of weeks or months.

Symptoms of a subdural hematoma include:

  • Confusion
  • Severe headache
  • Slurred speech
  • Coma

While some patients can be treated with surgery to drain the blood and reduce pressure on the brain, other cases resolve themselves in a matter of hours or days. This is known as rapidly resolving acute subdural hematomas (RRASDH). A recent California study done by Brooke M., Patel A., and Castro-Moure F., et. al. examined the causes and mechanisms of RRASDH, which are generally unknown. In fact, the research showed that less than 20% of all patients with acute subdural hematomas have RRASDH.

What Did the Study Reveal?

The researchers discovered some interesting conclusions regarding RRASDH. First, after studying 154 patients with acute subdural hematomas, those with RRASDH had lower levels of comorbidities (or multiple diseases occurring simultaneously) than those without RRASDH. This means that people with RRASDH generally experience less chronic diseases and health disorders, such as dementia, diabetes, and hypertension.

The study also found that patients with RRASDH had lower levels of blood thinning drugs and medications in their systems. In fact, lower levels of anticoagulants (blood-thinning substances) were the main predictor of RRASDH. This means patients with RRASDH may take less blood thinning drugs (such as aspirin) and have less anticoagulant levels in their bloodstream than those suffering from acute subdural hematomas.

Understanding the Implications of the Research

The study showed a possible negative correlation between anticoagulants and RRASDH. A higher level of blood thinning agents in the bloodstream from medications like aspirin were indicators in patients who suffered from acute subdural hematomas as opposed to those with RRASDH. Thus, anticoagulants may negatively affect the recovery rate in patients suffering from acute subdural hematomas. More research is needed to determine the correlation between blood thinning agents and RRASDH, and the following implications for patient recovery.
