BRAIN INJURY
So, what is a brain injury? Did you know there are a multitude of answers? Let’s explore. I will list them in alphabetical order.
ABI – Acquired Brain Injury – This term is used to describe injuries that may have occurred at birth, traumatic brain injury, as well as brain tumors, stroke, brain hemorrhage, and encephalitis to name a few. So this term is the “Broad Term” to describe brain injuries.
ALCOHOL RELATED INJURY – Drinking alcohol even in moderate amounts can lead to Brain atrophy. It can also interfere with brain cell function, creating long-term effects on the brain. Wernicke-Korsakoff Syndrome, Hepatic Encephalopathy, and Central Pontine Myelinolysis have all been identified as being linked to alcohol consumption. These are specific disorders can lead to vision impairment, muscular coordination conditions, and speech problems.
ANOXIC OR HYPOXIC INJURY – This occurs when the brain cells do not get enough oxygen. Left without oxygen for too long, neural cells begin to die through a process called apoptosis. This type of injury can occur during birth, and attack or assault, due to stroke, due to choking or anaphylactic shock, because of a drug overdose or a blow to the windpipe. It can also be caused by carbon monoxide poisoning. Symptoms include confusion, loss of consciousness, dizziness, vomiting, tingling in limbs, and intense headaches.
BRAIN ANEURYSM – This is also called “Cerebral Aneurysm” and is caused by a swelling of a weakened blood vessel inside of the brain. Aneurysms can grow over time, putting pressure on the brain. Often this condition goes unrecognized. Symptoms include headaches and fatigue.
BRAIN HEMORRHAGE – A brain hemorrhage is bleeding in or around the brain caused by an aneurysm, stroke, or traumatic brain injury. Hemorrhages are named according to where the bleeding occurs: Subdural Hemorrhage (Hematoma) – These are most common associated with TBI . A subdural hematoma is a collection of blood outside the brain. The bleeding and added pressure on the brain from this condition can be life-threatening. Blood collects between the layers of tissue that surround the brain; Extradural hemorrhage (Hematoma) - Is a collection of blood that forms between your skull and the dura mater, the outermost protective membrane covering your brain. The cause is usually an artery that gets torn by a skull fracture. Symptoms include severe headache and loss of consciousness. This can be a life-threatening condition that requires emergency surgery.; Subarachnoid hemorrhage - Is bleeding into the subarachnoid space, the area between the arachnoid membrane and the pia mater surrounding the brain. Symptoms may include a severe headache of rapid onset, vomiting, decreased level of consciousness, fever, weakness, numbness, and sometimes seizures; and Intracerebral hemorrhage – This type of hemorrhage is the second most cause of stroke. It is caused by bleeding into the brain tissue. Blood can damage the brain tissue as well as the increased pressure cause damage to the brain. Symptoms include headache, nausea, vomiting, fading in and out of consciousness, weakness or numbness in arms and legs, vision loss, seizures.
BRAIN INFECTION: Meningitis (inflammation of protective membranes), Encephalitis (inflammation of the brain itself, caused by a viral infection), and Brain Abscesses (localized collection of pus within the tissue) fall into this category. Symptoms include fever, headache, confusion, and seizures. For more information, you can follow this link: https://www.headway.org.uk/about-brain-injury/individuals/types-of-brain-injury/
BRAIN TUMOR: A brain tumor is a growth of cells in the brain or near it. Brain tumors can happen in the brain tissue. Brain tumors also can happen near the brain tissue. Nearby locations include nerves, the pituitary gland, the pineal gland, and the membranes that cover the surface of the brain. Brain tumors can begin in the brain. These are called primary brain tumors. Sometimes, cancer spreads to the brain from other parts of the body. These tumors are secondary brain tumors, also called metastatic brain tumors. There are too many types to mention here. For more information check out this link: https://www.mayoclinic.org/diseases-conditions/brain-tumor/symptoms-causes/syc-20350084. Symptoms include headache, nausea, vomiting, eye problems, loosing feeling or movement in an arm or leg, balance trouble, speech problems, fatigue, memory problems, behavior changes, dizziness, hearing problems, seizures.
CONCUSSION – This injury is often referred to as “Mild Head Injury” or “Mild Traumatic Brain Injury.” A concussion occurs when the brain is shaken back and forth inside the skull. Concussions often result due to a fall, road crashes, assaults, or sports accidents. Symptoms can include loss of consciousness (less than 30 minutes), and Post Traumatic Amnesia (PTA). The recovery period often involves dizziness, nausea, confusion, inability to process information, sensitivity to light, and vision distortion.
STROKE – Stroke is caused by a blood supply disruption to the brain. Blood supplies oxygen which is vital for the brain to function. There are two types of stroke; Ischemic Stroke, where a blood clot causes blockage; and Hemorrhagic Stroke, where a weakened blood vessel bursts, causing blood to leak into the brain. Symptoms of stroke are described by the acronym FAST; F – Face (Part of the face starts to droop, making smiling difficult); A – Arms (Person is unable to fully lift their arms); S – Speech (Person has difficulties with speech and slurs); T – Time (It’s time to call 911).
TBI – Traumatic Brain Injury – Describes brain injuries caused by trauma to the head and brain. Often caused by accidents, assaults, falls, and work accidents. Depending on the severity, this type of injury usually results in coma, loss of motor functions, and speech impairment. There can be a multitude of other conditions.
SUMMATION: Here is a great video explaining different types of brain damage, their causes, and their symptoms. It’s only 4 minutes long, but well worth watching.
