What are some of the major cellular and molecular pathways involved in the long-term pathology related to chronic disability in TBI and stroke?

There are several cellular and molecular pathways involved in long term pathology related to chronic disability in traumatic brain injury (TBI) and stroke. In TBI, some of the major pathways include the following.

1. Inflammatory Response: The inflammatory response after TBI can lead to the activation of microglia and astrocytes, which release cytokines and chemokines that can further exacerbate the injury.

2. Excitotoxicity: TBI can cause an imbalance in neurotransmitters, leading to increased glutamate release and excitotoxicity, which can damage neurons.

3. Oxidative Stress: TBI can lead to an increase in reactive oxygen species (ROS) production and a decrease in antioxidant defenses, leading to oxidative stress that can damage cells.

4. Apoptosis: TBI can activate apoptotic pathways, leading to cell death.

In stroke, some of the major pathways are as follows.

1. Ischemia-Reperfusion Injury: The lack of oxygen and nutrients during the ischemic phase of stroke can lead to cell death, while the reperfusion phase can lead to an influx of calcium and ROS, leading to further cell damage.

2. Inflammatory Response: Similar to TBI, stroke can also lead to an inflammatory response that can exacerbate the injury.

3. Excitotoxicity: Similar to TBI, stroke can also lead to an increase in glutamate release and excitotoxicity.

4: Apoptosis: Stroke can also activate apoptotic pathways, leading to cell death.

Overall, these pathways can lead to chronic disability in TBI and stroke patients, as they can cause long term damage to cells and tissues in the brain.
