What happens to the brain and neurons during a concussion 📹 Syntropy Studio

A brain concussion, also known as a mild traumatic brain injury (TBI), is a condition that occurs when a person experiences a blow or jolt to the head. It can result in temporary disruption of normal brain function. Symptoms may include headache, dizziness, confusion, memory problems, and sensitivity to light or noise. It's important to seek medical attention if you suspect a concussion. Take care and stay safe!

How concussion affects the brain

Hurts

Concussions impact brain & neurons! 🧠

A concussion is a type of traumatic brain injury (TBI) caused by a bump, blow, or jolt to the head, or by a hit to the body that causes the head and brain to move rapidly back and forth. This sudden movement can cause the brain to bounce around or twist in the skull, creating chemical changes in the brain and sometimes stretching and damaging brain cells. Here's what happens to the brain and neurons during a concussion: - Mechanical Impact: The initial impact can cause a mechanical deformation of neurons and other cells in the brain. This deformation can disrupt the normal function of neurons, including how they communicate with each other. - Neurochemical Changes: The mechanical impact leads to a cascade of neurochemical changes within the brain. There's a sudden release of neurotransmitters, which can cause neurons to become overexcited. This change in activity can lead to a temporary disruption in normal brain function. - Ionic Imbalance: Concussions cause a flux in ions, such as potassium and calcium, across the neuron's membrane. Normally, neurons maintain a careful balance of ions inside and outside the cell, but the trauma disrupts this balance. The influx of calcium, for example, can be particularly damaging as it can lead to further metabolic changes and stress within the cell. - Energy Crisis: The ionic imbalance forces the brain to expend more energy to restore the normal ionic balance, leading to an increased demand for glucose in the brain when the supply may be compromised due to reduced blood flow. This mismatch between supply and demand can lead to an energy crisis in the brain, making it more difficult for the brain to function normally and recover from the injury. - Axonal Injury: Concussions can cause stretching or shearing of axons, the long, threadlike parts of nerve cells along which impulses are conducted. This damage can disrupt the normal transmission of electrical signals in the brain. - Inflammation: In response to injury, the brain can initiate an inflammatory response, which, while part of the healing process, can also lead to further damage if it becomes too intense or prolonged. This inflammation can exacerbate the brain's energy crisis and contribute to symptoms like headache and sensitivity to light. - Blood-Brain Barrier Disruption: The trauma can lead to temporary disruptions in the blood-brain barrier (BBB), a selective barrier protecting the brain from potentially harmful substances in the bloodstream. When the BBB is compromised, it can lead to swelling and potentially allow harmful substances to enter brain tissue. The severity and duration of symptoms following a concussion can vary widely depending on the individual and the specific details of the injury. Symptoms can include headache, confusion, dizziness, memory loss, and others. Most people recover fully from concussions, but repeated injuries can lead to cumulative effects and increase the risk of developing chronic neurological disorders. Recovery involves physical and mental rest, followed by a gradual return to normal activities under medical guidance.

CTE neurons are damage and the brain may brusie at the site of impact. That increase dementia risk 🤷‍♂️... and we have 3 stages of concussion .
