How long after hitting head can concussion symptoms start?

The timing of concussion symptoms can vary widely. In some cases, symptoms can start right away after the head trauma. In others, symptoms may not become apparent until hours, or even days, after the incident.

If you experience any head trauma and have any concerns, it is best to seek medical attention as soon as possible.

Symptoms of concussion can include headache, confusion, memory problems, dizziness, light sensitivity, nausea, loss of balance, and difficulty concentrating. Any resulting symptoms can last for weeks, months, or longer.

If symptoms last for an extended period of time, it is important to follow up with your healthcare provider.

What are 3 delayed symptoms of a concussion?

There are a variety of delayed symptoms that can occur after a concussion. These can include:

1. Cognitive issues such as difficulty concentrating, planning, and organizing.

2. Physical symptoms such as headaches, neck pain, dizziness, and fatigue.

3. Emotional and mental health symptoms such as changes in mood, depression, anxiety, and irritability.

It’s important to note that these symptoms may not show up immediately after a concussion as sometimes they can take up to a week or even longer to appear. Additionally, they can last anywhere from a few days to several months.

If you or someone you know has experienced any of these symptoms, it’s important to seek medical advice right away as there may be treatments available to help alleviate them.

Can symptoms of a concussion show up later?

Yes, symptoms of a concussion may appear later. In some cases, the symptoms may not manifest for up to days after the injury has occurred. After suffering from a concussion, there are certain signs to look out for in the hours and days following the injury.

These signs include headaches, dizziness, confusion, difficulty concentrating, loud ringing in the ears, nausea, vomiting, fatigue, sensitivity to light and noise, confusion, slurred speech, and changes in vision.

If any of these symptoms appear later, it could indicate that the person has suffered a concussion. If any of these symptoms appear later, it is important to seek medical attention as soon as possible.

What are the symptoms of a slow brain bleed?

A slow brain bleed, also known as a chronic subdural hematoma (SDH), is a slow accumulation of blood in the brain over several weeks or months. It is a medical emergency, as it can cause severe neurological defects and even death, if left untreated.

Symptoms of a slow brain bleed can vary, depending on the size and location of the accumulation. Generally, symptoms may include persistent headaches that appear without an obvious cause and get worse with activity or when bending over, confusion and decreased mental clarity, personality changes, stiffness of the neck, lethargy and weakness on one side of the body, seizures, vision changes, nausea and vomiting, as well as speech and balance impairment.

In general, chronic subdural hematomas present more vague symptoms than acute subdural hematomas, such as headaches not associated with trauma, a decrease in mentation or changes in behavior or visual symptoms.

If you experience any of these symptoms, it’s important to seek medical care as soon as possible to minimize the potential for long-term brain damage or death.

Can you have a brain bleed and not know it?

Yes, it is possible to have a brain bleed and not know it. This type of brain bleed is called a silent or insidious brain bleed, which means that people may not immediately recognize any signs or symptoms.

A silent brain bleed can occur in any part of the brain, including the cerebellum, the pons, the thalamus, and the brain stem. Symptoms of a silent brain bleed may not be noticeable initially, but over time can include headaches, dizziness, nausea, confusion, difficulty speaking, difficulty controlling movements, and loss of consciousness.

In most cases, a person would need to undergo imaging tests such as an MRI or CT Scan in order to detect a silent brain bleed. If a person is experiencing any of the symptoms listed above, or if they have suffered a head injury or have a bleeding disorder, they should consult a doctor right away.

What happens if a concussion goes untreated?

If a concussion goes untreated, it can lead to a wide range of long-term health problems that can last for months or even years after the initial injury. Depending on the severity of the injury, a person may experience headaches, dizziness, memory loss, confusion, balance problems, sensitivity to light and noise, and even depression or mood swings.

The risk of developing post-concussion syndrome increases if the injury is not treated properly. Post-concussion syndrome is a cluster of neurological and cognitive symptoms that appear weeks or months after the initial injury, and can include difficulty concentrating, fatigue, irritability, depression, and difficulty sleeping.

People who experience a severe concussion are at a higher risk for developing long-term brain damage, such as a traumatic brain injury, which can cause permanent disabilities. Other long-term effects that can occur with an untreated concussion include increased risk of stroke and difficulty regulating blood pressure, as well as an increased risk of developing chronic traumatic encephalopathy (CTE).

CTE, a degenerative brain disease, has been linked to depression, dementia, and other neurological problems in those who suffer from it. All of these dangers can be avoided by following proper concussion management and seeking medical treatment immediately after any head injury.

What is the concussion test?

A concussion test is a brief physical and cognitive assessment used to identify the presence and severity of a concussion. It is typically conducted by a medical professional, such as a doctor, nurse practitioner, or athletic trainer, and includes questions about the person’s symptoms and medical history.

Depending on the severity of the injury, a physical examination may also include a neurological assessment and balance tests. The concussion test aims to assess any potential changes in the person’s behavior, motor function, thinking, and senses, which can all be impacted by a concussion.

A concussion test usually takes a few minutes to complete and results are usually compared against a baseline test (if available) which was conducted prior to the injury.

What delayed concussion feels like?

Delayed concussion symptoms can be difficult to identify and may not show up until hours, days, or even longer after the initial head trauma or a concussion occurs. Symptoms may include:

• Headache – A lingering headache may be a symptom of a delayed concussion.

• Dizziness – Many people that experience a concussion will feel lightheaded or dizzy during the days and weeks that follow as a result of the brain injury.

• Difficulty concentrating – A concussion often causes difficulty processing and retaining information. This could manifest as difficulty concentrating or difficulty with memory recall.

• Feeling sluggish or groggy – A concussion can cause fatigue, lack of energy, and feeling like one is in a fog.

• Loss of balance or difficulty with coordination – As a result of the brain injury, a person may feel like they are off balance and having trouble coordinating their body movements.

• Irritability or mood swings – The emotional and mental effects of a concussion can often lead to mood swings and periods of irritability.

• Visual disturbances – Some people dealing with a concussion may experience blurry vision or difficulty focusing their eyes on an object or task.

• Sensitivity to light and sound – People with a delayed concussion may be sensitive to light and sound, such as loud noises.

Why are concussion symptoms sometimes delayed?

Concussion symptoms are sometimes delayed because the brain may take hours or even days to heal and fully recover from the trauma it experienced. The symptoms are often overlooked or not noticed right away because the person may not recognize that they have sustained a head injury.

Brain injuries can also cause complications, such as changes in brain chemistry or inflammation that can further disrupt brain functioning, resulting in delayed symptoms. Additionally, some people may experience a release of hormones called the “flight or fight” response, which helps to protect the body from further damage.

These hormones can cause an individual to not truly recognize the extent of their injury. The combination of all of these factors can lead to delayed concussion symptoms.

How do you know when to get your head checked after hitting it?

If you hit your head and experience any of the following signs or symptoms, it is important to get checked out by a doctor as soon as possible:

– excessive head or neck pain

– nausea and/or vomiting

– confusion

– changes in vision

– ringing in the ears

– dizziness

– fatigue or listlessness

– changes in behavior

– loss of consciousness

– seizures

It is especially important to seek medical attention if there is any bleeding or an open wound, any signs of bruising or swelling, a severe headache that intensifies, or if you experienced any blunt force trauma (being hit, falling, etc.


If you have previously had a concussion or head injury and experience any of the symptoms after hitting your head, it is important to consult with your doctor as soon as possible to have the injury assessed and to determine whether it is safe to return to regular activities.

What to watch for after hitting head?

If you or someone you know has hit their head, it is important to keep an eye out for the following possible symptoms:

1. Behavioral Changes: Watch for any changes in mood or personality after the head injury. Pay particular attention to irritability, abnormal emotional behavior, confusion, or an overall decline in alertness.

2. Difficulty with Vision: Blurry or double vision can indicate a more serious injury.

3. Balance and Coordination: Issues with balance and coordination can also indicate a head injury.

4. Dizziness: Dizziness or vertigo can also be a sign of head injury.

5. Loss of Consciousness: Loss of consciousness can also signify a more serious injury. If the individual regains consciousness, but is still feeling confused or disoriented a few hours later, they should seek medical attention.

6. Headaches: Severe headaches that are persisting and not responding to pain medication may be a sign of a head injury.

7. Memory Loss: Memory loss can also be a sign of a head injury, so pay close attention if the individual seems to have trouble with recall of recent events or conversations.

It is important to recognize any of these symptoms after a head injury and seek medical attention if you have any concerns.

How do you test yourself after hitting your head?

If you have hit your head and are concerned about your health, it is important to be aware of the potential concussion signs and decide if you need to seek medical attention. A good way to test yourself is to complete what is known as the “SCAT3 Neurocognitive Test”, which stands forSport Concussion Assessment Tool 3.

The SCAT3 tests your reaction time and cognitive abilities, such as memory and recall, in order to assess the severity of a concussion. It requires you to read a couple of pages of instructions and follow the directions there.

The test has three components: the symptom evaluation, the physical examination, and the cognitive exam.

The symptom evaluation section is used to assess any symptoms associated with a concussion. It is important to be honest and accurate about any symptoms you are experiencing in order to accurately evaluate the seriousness of your head injury.

Common symptoms include feeling lightheaded or dizzy, difficulty concentrating or remembering, sensitivity to light and noise, nausea, or headaches. It is very important to note any changes in your behavior which may be an indication of a concussion.

The physical exam checks for the presence of risk factors such as eye movements, muscle strength, balance, and coordination. If any of these have decreased since before the injury, it may be more likely that you have suffered a concussion.

The cognitive exam assesses your cognitive function. It includes tasks that assess your short term memory, your executive functioning, and your verbal fluency. It is important to note any difficulty with these tasks that was not present before the injury.

Once the SCAT3 test has been completed, the results can provide useful information about the severity of your head injury. If there is any concern related to the results, it is very important to seek medical attention.

What not to do after getting hit in the head?

After getting hit in the head, it is important to take measures to ensure that you have not sustained a serious injury. Never try to “shake off” the feeling of head trauma, as this could result in further injury.

Do not ignore signs of concussion, such as headache, dizziness, confusion, or ringing in the ears. Instead, seek immediate medical attention if you are experiencing any of those symptoms.

Certain precautions should also be taken to reduce the effects of head trauma. Do not drink alcohol, take medications, or engage in strenuous activities. Make sure to get plenty of rest and refrain from driving or operating machinery.

If available, let a family member or friend observe you for any changes in behavior or performance.

Above all, never assume that a head injury is minor. Even a slight bump on the head can lead to serious complications if not treated promptly. If you suffer a head injury, seek medical attention as soon as possible.

How do I know if I hit my head hard enough to cause damage?

It is important to assess any impact to the head to determine if there is any risk of damage. General guidelines suggest that any hit that is hard enough to cause a headache or nausea, results in a loss of consciousness, produces a cut or bruise, or causes changes in the person’s behavior should be evaluated by a healthcare professional.

It is also important to be aware of any symptoms, such as confusion, memory problems, balance issues, blurred vision, nausea and vomiting, that may appear in the hours and days after the head injury.

If any of these signs develop, medical attention should be sought. Additionally, repeated head injuries, no matter how minor, can increase the chances of damage. A healthcare professional is best equipped to assess the risks of impact-related head trauma and recommend appropriate treatments.
