This lesson will discuss a lot of different yet similar conditions that affect the brain's vasculature. Namely, we'll cover strokes, transient ischemic attacks, and aneurysms. We'll also discuss why they may occur, how they can be diagnosed, and how they may be treated.
10. Nervous System Tumors: Gliomas, Meningiomas, and More
This lesson will go over some of the most common nervous system tumors and how it is they may cause harm to the person, how they may be diagnosed, and treated. Find out as we explore meningiomas, gliomas, and schwannomas.
11. The Mechanism of Spinal Cord Trauma
This lesson will go over the things that can traumatize your spinal cord, what spinal cord trauma may result in, and why that may occur. We'll also focus in on some of the specifics of spinal shock and autonomic dysreflexia.
12. Traumatic Brain Injury (TBI): Diagnosis, Rehab & Recovery
Traumatic brain injury (TBI) is a rather broad term that refers to an injury to the brain that is caused by some type of trauma or external force. This lesson is about the causes and diagnosis of traumatic brain injury, rehabilitation, and recovery.
13. Depression & Long-Term Effects of Traumatic Brain Injury
