  https://completeconcussions.com/concussion-tips-information/the-big-book-of-concussion-symptoms-what-is-expected-and-what-may-be-a-sign-of-trouble/

  Many different symptoms can occur after sustaining a concussion, and they are generally broken down into 4 main categories: physical, cognitive, emotional, and sleep. Every concussion is unique, so there are no two concussions that are going to present the exact same in terms of what symptoms are experienced, the intensity of the symptoms, how long the symptoms take to develop, and how long until they resolve. […] Depending on the symptom, it may be present immediately following the traumatic brain injury, such as dizziness or feeling in a fog, and some will develop in the coming hours to days (within 48 hours). Therefore, it is essential to both keep track of what symptoms you are experiencing day to day and to get assessed by a qualified healthcare practitioner so they can determine if the symptoms you are experiencing are related to your concussion and help you with strategies about how to resolve them.

  Concussion symptoms can start immediately, within hours, or even days later. […] Delayed symptoms are common and can include headaches, memory issues, and fatigue. […] One of the most perplexing aspects of concussions is the delayed onset of symptoms. Some people feel fine immediately after the impact but later develop headaches, memory problems, or dizziness. […] For many people, symptoms don’t become noticeable until well after the initial impact. This delayed response occurs because concussions involve not just the initial trauma, but also a complex series of chemical changes in the brain that take time to develop.

Its believed that around 50% of people with a history of mTBI (mild traumatic brain injury) or concussion are still experiencing symptoms three months after their injury, and at a year that number has dropped to 10-15%, meaning that the majority of the symptoms go away within a year of the injury.” […] The Center for Disease Control Prevention notes that „In general, recovery may be slower among older adults, young children, and teens.” […] „Treatment of PCS typically focuses on relieving the individual symptoms, as the underlying cause of PCS isn’t known and therefore can’t be addressed as a condition.” […] PCS can be extremely disruptive to a patient’s life.

  PCS is a relatively common complication of concussion recovery. It’s estimated that PCS may be diagnosed in 20 percent of concussion patients. […] The recovery process after an accident is multifaceted, involving physical, emotional, and cognitive healing. PCS can complicate this process, with symptoms persisting for months or even years, affecting daily functioning and quality of life. […] Predicting who will experience PCS is challenging, but research offers insights into individuals who may face a higher risk. […] Certain risk factors may seem intuitive or obvious, such as a major blow to the head. If someone experiences a hit that leaves them completely incapacitated, it is reasonable to anticipate a longer concussion recovery compared to someone who sustained a less severe impact.

• #99 What is PCS? | Concussion Legacy Foundation

  https://concussionfoundation.org/pcs-resources/what-is-pcs/

  Some individuals experience a double impact, where they sustain a blow to the head, fall, and subsequently receive another blow when their head hits the ice, boards, or field. These double impacts may result in a more severe concussion and increase the likelihood of developing PCS. […] Another factor to take into account is whether someone has pre-existing conditions such as a concussion, attention deficit disorder (ADD) or ADHD, depression, anxiety, migraines, or a seizure disorder. Having these underlying conditions can heighten the effects of a concussion, both in the short term and potentially over a prolonged period. […] It’s important to note that PCS differs from Chronic Traumatic Encephalopathy (CTE), a progressive and degenerative disease resulting from repetitive head trauma. While CTE develops over time, PCS refers to symptoms that begin minutes, hours, or days after a concussion and don’t resolve within a month. […] PCS improves over time and, with treatment, often leads to full recovery. On the other hand, CTE is a progressive degenerative brain disease. Symptoms usually appear many years after an individual was exposed to repeated head impacts.

If these symptoms persist beyond three months, they’re called persistent post-concussive symptoms. […] Never return to play or vigorous activity immediately following a concussion. Experts recommend that adult, child and adolescent athletes with concussions not return to play on the same day as the injury.

Therefore, when a traumatic event such as a concussion occurs, somatic, cognitive, behavioral, and sleep impairments are the common outcome. Each concussion is unique in the sense that the magnitude of biomechanical forces and the direction, rotation, and source of those forces are different for each concussive event. This helps to explain the unpredictable nature of post-concussion symptoms that can arise and resolve. […] The variety of post-concussion symptoms indicates how a range of brain regions could be implicated during a single concussive injury, and why damage to specific brain regions may explain patient-specific symptoms.

However, about 20 percent of children will go on to suffer symptoms for an extended period of time beyond one month. […] Typically, if symptoms last longer than one month, your child will require active rehabilitation to aid in their recovery. Common symptoms that seem to linger include: Vestibular system deficits (brains ability to visually track and focus and maintain balance), Exercise continues to induce physical symptoms (headache, nausea), Cognitive deficits (memory issues, attention deficits and challenges in problem solving), Alterations in mood (irritability, sadness and depression). […] In individuals with prolonged concussions, mood disorders are common. In general, we’ll look for mood disorders for people with prolonged concussion symptoms. If they have mood disorders, then they will be referred to the appropriate specialist.

  Similarly, vestibular issues can also lead to PCS symptoms. Concussions can disrupt the connection between the vestibular system (located in the inner ear) and the brain and lead to symptoms like dizziness, poor posture, instability when walking, fatigue, and difficulty performing routine daily activities. […] The brain has an innate ability to recover from injuries like concussions. This process is called neuroplasticity, and it refers to the brain’s ability to change, reorganize, or even grow new neural networks in response to stimuli. […] If you leave your brain to recover naturally without any form of treatment this process will still happen, but it is entirely possible that the new neural pathways will not be the most effective ones, and that they will even aggravate your recurring symptoms.

  Sometimes children take longer than adults to get better. Certainly, there are some cases where kids can have a concussion and they can recover within a few days. But there are definitely many cases where kids can take longer. […] In a subset of patients who have prolonged symptoms, usually about 10 percent of adolescent concussions, rest is no longer a benefit for them. […] If an individual can be back in school in two or three days, that’s ideal. If the injury is more severe, it may take them more than a few weeks to get back to full school. […] The earlier you take care of it, the better off you’re going to be. But if you delay pulling yourself out and getting the rest that you need to get your concussion to heal, the more likely you are to have issues that will be longer in terms of symptoms and recovery.

  According to the Mayo Clinic, „the risk of developing persistent post-concussive symptoms doesn’t appear to be associated with the severity of the initial injury.” […] However, numerous studies do show a relationship between the severity of early concussion symptoms (within 24 hours) and longer recovery times. […] Dr. Elizabeth Sandel says, „The prognosis for PCS is good. Its believed that around 50% of people with a history of mTBI (mild traumatic brain injury) or concussion are still experiencing symptoms three months after their injury, and at a year that number has dropped to 10-15%, meaning that the majority of the symptoms go away within a year of the injury.” […] The Center for Disease Control Prevention notes that „In general, recovery may be slower among older adults, young children, and teens.” […] „Treatment of PCS typically focuses on relieving the individual symptoms, as the underlying cause of PCS isn’t known and therefore can’t be addressed as a condition.” […] PCS can be extremely disruptive to a patient’s life.

  Symptoms are not always present right after the injury. They can become apparent hours or even days after the injury. […] The most common symptoms following a concussion are headaches, and “cognitive delay,” when the brain cannot process information as efficiently as it did before the injury. The person feels like they can’t “keep up” and it is harder to maintain attention. It can feel like being in a fog all the time. This requires the person to spend more cognitive energy to complete tasks that were simple before the injury. […] Towards the end of the day, a person can feel exhausted physically and cognitively and may become more irritable and more easily frustrated. Other symptoms, like headache, may also appear or worsen. […] The timetable for recovery varies. Younger children and older adults tend to take longer to recover. People who try to rush things and don’t manage their symptoms tend to take longer to recover. […] If you are having symptoms that are not resolving or are getting worse, you should discuss these symptoms with your doctor.

[…] Post-concussion symptoms can persist or recur years after the original injury. In general, PCS symptoms tend to stay the same or get worse over time until they are properly treated. […] Many studies have found that PCS recovery time varies drastically. Some patients recover after a couple of weeks without any long-term side effects; others struggle with symptoms for the rest of their lives. Some studies even go as far to state that PCS may be permanent if recovery has not occurred by 3 years.

  The key to a speedy recovery is both physical and mental rest. […] Recovery phase occurs once the patient feels physical improvement, such as headaches subsiding, and postconcussion neurocognitive test scores have improved. […] However, academic accommodations may be required during the recovery phase because the concussion may still affect thinking, attention, focus, memory, learning speed and mental processing. […] Chronic phase occurs in some cases when the patient may experience more long-lasting (chronic) problems with cognitive function. […] If unmanaged, these problems have the potential to significantly impact the patients life as a whole. […] Patients who are in the chronic phase of a concussion will be referred to one of our neuro rehab specialists who will treat the chronic symptoms. […] No two concussions are exactly the same, so individualized treatment is necessary. […] While most people with a concussion recover quickly and fully, some will have symptoms that last for days or even weeks. A more serious concussion can last for months or longer.

  According to the Mayo Clinic, „the risk of developing persistent post-concussive symptoms doesn’t appear to be associated with the severity of the initial injury.” […] However, numerous studies do show a relationship between the severity of early concussion symptoms (within 24 hours) and longer recovery times. […] Dr. Elizabeth Sandel says, „The prognosis for PCS is good. Its believed that around 50% of people with a history of mTBI (mild traumatic brain injury) or concussion are still experiencing symptoms three months after their injury, and at a year that number has dropped to 10-15%, meaning that the majority of the symptoms go away within a year of the injury.” […] The Center for Disease Control Prevention notes that „In general, recovery may be slower among older adults, young children, and teens.” […] „Treatment of PCS typically focuses on relieving the individual symptoms, as the underlying cause of PCS isn’t known and therefore can’t be addressed as a condition.” […] PCS can be extremely disruptive to a patient’s life.

  Post-concussion syndrome can go on for weeks, months, or even years. It is a tough situation because the symptoms can significantly affect your everyday life. […] Patients with active lifestyles or who are used to working will find it challenging to do nothing during the resting period. […] Because sometimes the symptoms dont appear until days or weeks after the incident. Moreover, there is a risk of developing post-concussion syndrome. Symptoms persisting months after the injury is a red flag for that. […] The hardest part about having post-concussion syndrome is there is no single cure for it. Patients may experience similar symptoms, but the duration, severity, and how they respond to treatment differ. […] The best way to manage long-term concussion symptoms is to undergo brain injury rehab and therapy. While rest is necessary for the brain to heal, it is also crucial that patients do cognitive exercises to recover.
