Headaches. Dizziness. Brain fog. Constant fatigue. Feeling overwhelmed or like your emotions can’t stabilize. These and so many other symptoms can remain for months, or even years, after a concussion. If you feel like your recovery is excruciatingly slow, you’re not alone. Up to 30% of people who suffer a concussion experience persistent symptoms for months or years later.

After suffering a mild traumatic brain injury, you might expect to feel off for a few days before being able to function at your normal level again. However, a rapid return to normal is not the case for everybody. If symptoms like headache, dizziness, neck pain, fatigue, trouble concentrating, insomnia, or mood changes linger for weeks or months after your concussion, you may be suffering from post-concussion syndrome (PCS).

Many hospitals offer robust medical treatment to help patients survive traumatic brain injuries (TBIs). It’s common for those same hospitals, or affiliated care providers, to offer rehabilitation to patients after the danger of death has passed. These rehabilitation services often focus on activities of daily living (walking, dressing yourself, eating, etc.). It’s less common to find appropriate rehabilitative medical care for long-lasting symptoms following TBI

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.

COVID-19 can affect the autonomic and central nervous systems. It can affect organ systems directly through infection or indirectly via dysfunction in the nervous system. That means a host of crazy-sounding symptoms — such as blood pressure changes, memory and attention issues, and gastrointestinal upset — are possible during and after COVID. But many of the lingering, post-COVID symptoms are related to nervous system dysfunction.

Many people are surprised to learn that concussions can have long-term effects if left untreated. Chronic concussion syndrome is a less common term for persistent post-concussion symptoms (also known as post-concussion syndrome, or PCS). If you suffer from headaches, brain fog, vision issues, fatigue, short-term memory problems, irritability, feelings of overwhelm, or other persistent symptoms after a head injury, you might have chronic concussion syndrome.

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.

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.

Headaches are one of the most common neurological symptoms being experienced by COVID-19 long-haulers, and some patients even experience daily, persistent headaches.
