Types of TBIs

Andy Galpin breaks down the different types of traumatic brain injuries (TBIs), including concussions, and their varying symptoms and severity. He explains that TBIs can involve physical damage to brain structures, leading to energy deficits and prolonged inflammatory responses 1. Concussions, often mild TBIs, are associated with symptoms like confusion and amnesia, while moderate and severe TBIs can lead to long-term cognitive and behavioral issues 2.

Concussion is effectively a mild traumatic brain injury. Based on those categories, if you had worse effects, so you were unconscious for longer or your amnesia lasted longer, then you may actually be considered to be in a moderate category.

Understanding these distinctions helps in recognizing and addressing the impact of TBIs on individuals.

   

Pathophysiology

The pathophysiology of TBIs involves complex changes in the brain, including excitotoxicity, inflammation, and cell death. Andy Galpin describes how initial responses to brain injury include overactivation of neurons and excitotoxicity, primarily driven by the neurotransmitter glutamate 3. This leads to energy imbalances, as the brain struggles to produce enough ATP, resulting in symptoms like brain fog and cognitive deficits 4.

Reduced ATP production simply means we have way more cellular energy in our brain. This idea of brain fog or fatigue, or can't remember things, recall executive decision. If you don't have energy, your brain can't think.

These disruptions highlight the importance of addressing both the immediate and long-term effects of TBIs.
