After a concussion or other brain injury, your loved one may start exhibiting some behaviors that are considered inappropriate and childlike. They may be prone to crying (emotional lability), angry outbursts, impulsive behaviors, and more. It may seem like their words and behaviors are out of character or that they’re failing to understand and respect the feelings of others.
If left untreated, whiplash can cause long-term symptoms that are unlikely to go away on their own. Studies show that some patients recover within the first three months after their neck injury, but if they’re still experiencing symptoms past this period, improvement is unlikely without appropriate treatment. For example, hockey player Sidney Crosby suffered for months until doctors recognized untreated whiplash. Once he received appropriate treatment, he was able to continue with his career.
Whiplash can cause physical and neurological damage that results in long-term symptoms. In addition, the same event that caused whiplash could also have caused a concussion. (The sudden motion can cause the brain to collide with the skull even if there is no external impact on the head.) Concussions can develop into post-concussion syndrome (PCS), with symptoms persisting for months or even years.
Carbon monoxide (CO) poisoning can lead to severe long-term cognitive, physical, and behavioral symptoms, such as problems with memory, difficulty concentrating, balance issues, and mental health problems. Symptoms can continue even when the source of the gas is removed. Patients affected by CO poisoning can experience symptoms for months or even years after exposure.
Most patients with COVID-19 recover within a few days or weeks after a brief acute infection. However, about 10% experience long-term symptoms such as brain fog, fatigue, headaches, shortness of breath, and even psychological issues like depression and anxiety. Experiencing these persistent symptoms is known as long COVID, long-haul COVID or post-acute sequelae of SARS-Cov-2 infection (PASC).
At the moment, treatment options for long COVID patients are limited. Many patients cope with their symptoms using existing medications or treatments targeting specific symptoms like headaches or sleep problems, but these efforts are just stopgaps. They don’t actually resolve the underlying cause of symptoms associated with long COVID. Researchers know there is a growing need to identify new and effective treatments for these patients.
After a concussion or other type of traumatic brain injury (TBI), some patients experience persistent symptoms for months, or even years. This condition is known as post-concussion syndrome (PCS), and it can affect patients of any age.
“Post-traumatic brain injury syndrome” refers to long-term repercussions from concussions and other head injuries. Someone using this term could be referring to one of three conditions:
Long COVID symptoms such as fatigue, muscle weakness, joint pain, poor endurance, and respiratory problems can have a significant impact on your daily routine. Some long COVID patients’ symptoms are so severe that they need a reduced work schedule or are no longer working due to their illness. Persistent symptoms can follow both mild COVID and cases that required treatment in the ICU.
Neural fatigue can develop after any type of brain injury, including mild traumatic brain injury (concussion), severe traumatic brain injury (TBI), hypoxia, viral infection, stroke, or transient ischemic attack. It might surface immediately or after some time and can last for months or even years. It can also develop in patients with neurological disorders, such as Parkinson’s disease, multiple sclerosis, and dementia.
Long COVID is real. Data shared by the Centers for Disease Control and Prevention (CDC) from the Household Pulse Survey (July/August 2022) show that more than 40% of adults in the United States have had COVID-19, and nearly one in three of them (approximately 30%) experience symptoms for more than three months after their original acute infection. Not all patients with long COVID are severely affected, but the report estimates that two to four million Americans are currently unable to work because of persistent COVID symptoms.
Memory and attention problems are common in long COVID patients: A recent study showed that 70% of COVID long haulers experience memory and concentration difficulties for months after their initial disease. If you’re one of them, you might struggle to focus on work, forget where you left your keys, struggle to remember an acquaintance’s name, or space out unintentionally during a conversation.
COVID-19 can cause cognitive symptoms in some patients, such as short-term memory loss, difficulties concentrating, problems recalling words, and brain fog (a condition known as long COVID). While most initial studies focused on patients hospitalized with severe COVID symptoms, it became apparent that most long COVID patients developed their condition after only a mild case of COVID.
Headache pain is the most common symptom after a traumatic brain injury, with up to 90% of patients experiencing this symptom for at least a few days after suffering a concussion. These headaches can also develop after other causes of head trauma, such as bacterial and viral brain infections, carbon monoxide poisoning, “chemo” brain, transient ischemic attack, and COVID-19.
After headaches, dizziness is the second most common symptom patients experience after a concussion. Although this symptom often resolves by itself, it becomes persistent and debilitating for some patients. If patients experience dizziness or other concussion symptoms for more than three months, they may have post-concussion syndrome (PCS).
If you’ve been experiencing headaches for weeks, or even months, after your initial COVID infection, you are not alone. Headaches are one of the most common neurological symptoms being experienced by COVID-19 long-haulers, and some patients even experience daily, persistent headaches. But they’re often just one of many symptoms long COVID patients report. Other common symptoms include fatigue, brain fog, gastrointestinal issues, and more.
When the pandemic started, we were told that children wouldn’t be seriously affected by the virus. And while most children only experience a mild version of the disease, evidence shows that some children are at risk of developing persistent symptoms after their initial COVID-19 infection.
More than two years since the COVID-19 pandemic started, the list of symptoms caused by the virus keeps getting longer. In addition to the most common symptoms of a persistent dry cough, fever, and shortness of breath, many patients experience an array of seemingly random body changes both during and after the acute phase of the disease. We’ll discuss a number of them, including but not limited to:
Have you ever caught yourself holding your breath while doing something challenging? Or feeling lightheaded and breathing faster when you stand up after sitting for a long time? Maybe you often have rosy cheeks without a reasonable cause, like exercise.
Your heart races when you stand. You hate the dizzy spells. Your head hurts, you’re exhausted, and you can’t think clearly like you used to.
