Head Injuries - Types, Causes, Treatments

Any injury that causes damage or injury to the scalp, skull or the brain, can be called a head injury. It can be a minor bump or major physical damage. When the brain is affected, it is called Traumatic Brain Injury and can drastically change the physical and mental status of a person. They are also a major cause of death and disability.


Concussion - where the head is shaken so hard that the brain literally bounces off the side of the skull. This can range from mild to severe. Any sudden deceleration of the body or impact elsewhere can cause the brain to move in the cranium.

Contusion - where a bruise forms on the brain itself, leading to bleeding and swelling.

Intracranial Hematoma - where there is bleeding in the skull that then forms a clot. And, depending on where they form, can range from mild to severe.

Edema - this is swelling to injured tissue. When it happens to the brain tissue, the skull cannot stretch to accommodate the swelling, leading to pressure buildup, pressing the brain against the skull.

Skull Fracture - here the skull bone is fractured and cuts into the brain causing all kinds of complications.

Diffuse Axonal Injury - as there is no visible sign outside, this is one of the most dangerous, often leading to brain damage or death. Here there is damage to the brain cells, but no bleeding. This prevents their function, often leading to more swelling and damage.


Vehicular accidents are the most common, followed by accidents at home or workplace and involvement in acts of violence.


This depends on the type and severity of the injury.  Minor injuries may need nothing more than pain medication. But, if there is a cut, it may need to be closed and medicated. Serious injuries may need hospitalisation and the treatment can be:

Medication - as there is a possibility of seizures, anti-seizure medication may be prescribed. Medication to increase the amount of water and salt excretion from the body called Diuretics, may be prescribed. This reduces pressure build up caused by Edema. Sometimes the patient may have to be put into an induced coma, as then the brain needs less oxygen and nutrients.

Surgery - this is an emergency procedure and may have to be carried out to repair physical damage to the skull; release internal buildup of  pressure inside the skull; to remove a hematoma, which is the buildup of blood outside the blood vessels.

Rehabilitation - any serious brain injury could lead to loss of functionality, and regular rehabilitation will be necessary to retrain the brain to normal functioning. What this will be depends on what functionality is lost.

Head injuries are not to be taken lightly and medical help must be sought without any delay.

Tips to stimulate the brain during a lockdown

The whole world is in the midst of an unprecedented lockdown in response to the Covid-19 pandemic. People everywhere are spending long periods of time indoors, and this is having a detrimental effect on their health, both mental and physical.

Following are some of the steps that we can take to stimulate the brain and hence our mental health.
  1. If you or anyone in your family is on medication, maintain the stock, and make sure it is taken regularly. 
  2. In house exercise routine: a regular exercise routine is not just a way to kill time, but also to stay healthy. A healthy mind in a healthy body. And, if we can make it a family affair, the better it is. The family that exercises together, stays together. The internet is brimming with resources, from old fashioned PT exercises to newer specialised ones. But, do consult with your doctor before you do.
  3. Meditation and/or breathing: meditation works, and has been shown to reduce anxiety, depression and sometimes increase brain volume in specific areas. If that is not your thing, then just breathe. Yes, you already do that but start doing so in a focussed manner. It increases blood oxygen levels and reduces stress levels.
  4. Maintain or renew social or community connections: take that phone, call your friends, family, neighbours. Check up on their affairs, connect with them. We are social animals, we need this connection. Make it; keep it.
  5. Brain exercise: Anything that gives your brain a workout is acceptable. Puzzles of all kinds; chess, Go, knowledge quizzes. It is not the winning, but the playing, the together time, that matters.

Remember, the pandemic is not going anywhere soon. But, that does not mean we should give up.  Stay healthy, stay safe.

Awake craniotomy: What you need to know?

Awake craniotomy is a type of brain surgery, during which the patient remains awake. This procedure is carried out to manage cancer of the brain and skull base. A general anesthetic is used to minimize discomfort during the procedure.

 Brain tumor

Why is it done?

Awake craniotomy is usually recommended when a brain tumor involves or is close to parts of the brain that control vision, movement or speech and that must be preserved. This can avoid any potentially life-changing damage during the surgery. 

Why is the patient kept awake?

Awake craniotomy is often opted, when the Functional MRI can not pinpoint the most critical areas of the brain which are to be preserved. These vital areas are located using special speech mapping techniques while the patient is awake in the operating room. Awake speech mapping is carried out by applying a mild electrical current to the surface of the exposed brain. 

The patient will be asked to perform various tasks, such as reading or talking or blinking or moving fingers. Surgeons will monitor reflexes and reactions and when stimulation hinders the task, then that area of the brain is marked and preserved. When the stimulation blocks the task, it is considered as the area of the brain that is marked and preserved. This can minimize the complications impacting the patient’s sight, speech or movement. 

How is the surgery performed?

Patients will receive general anesthesia before surgery. This will keep them relaxed and calm throughout the procedure. The surgeons will make an incision and remove a small portion of the skull and start awake speech mapping. According to the stimulation, the surgeons will mark and protect critical areas of the brain that control important functions. Awake craniotomy usually lasts four to six hours. After which the patient will spend one to three days in observation, depending on the condition return to normal activity within one to two weeks. 

Is it painful?

Awake craniotomy is not painful. As mentioned earlier, the patient will receive general anesthesia and they don’t feel any discomfort. One interesting fact is that the brain doesn’t have any pain receptors so the surgeon can operate without risk of causing pain.  

Just like every other brain surgery an awake craniotomy is a highly complex procedure. However, compared to other brain surgeries awake craniotomy facilitates safe and faster recovery. Most often, 75 percent of patients can go home 24 hours or less after surgery.

Recovery after endoscopic skull base surgery

Endoscopic skull base surgery is the surgery to treat the disease like the tumor or an infection in your brain. This surgery involves open brain surgery to treat.

Complications you may experience after endoscopic skull base surgery:
  • You may also have headaches or problems concentrating. It can take up to 4 to 8 weeks to recover from surgery.
  • Your wound may be painful after surgery for a minimum of 5 days. 
  • You might experience shooting pains and numbness near your incisions, or bruising and swelling may appear around your eyes. 
  • The stitches of your wounds go away on their own or need to be removed by doctors within 7 to 10 days, depending on the stitches type.
Here are the following steps to recovery after endoscopic skull base surgery:
  •  Getting enough sleep will help you recover.
  •  Avoid resting or sleeping in a flat position. You can also raise the headboard of your bed or use a wedge pillow. It prevents headaches or dizziness.
  •  Start walking every day because it boosts the flow of blood and prevents constipation and pneumonia.
  •  Avoid heavy lifting or exercising until your doctors give you heads up.

  •  There is no particular diet; you can maintain a regular diet. However, when you get bad feelings in the stomach, try low-fat foods or bland, like boiled chicken, toast, plain rice, and yogurt.
  •  Fluid intake should be under a doctor’s recommendation.
  •  Avoid drinking alcohol during the recovery procedure.
  • Take medicines only prescribed by doctors.  Also, you need to complete the full   course of medicines as prescribed by your surgeon.
  •  Keep the wound clean and dry. Change the bandage as directed by your doctor.
  •  Follow-up with your doctor regularly and take only prescribed medicines. Also, do not exceed or suppress the dosage of your medicine.
  •  Call your doctor if you are having any problems even unrelated to your surgery. 
This is a general idea about recovery. However, each person recovers at their pace.

What Causes Craniocervical Instability

The craniocervical junction is the place where the skull and the upper spinal cord meet. Craniocervical instability, also known as the syndrome of Occipitoatlantialaxial Hypermobility, is a pathological condition that causes structural weakness in the craniocervical junction. This instability might lead to the deformation of the upper spinal cord, brain stem, and cerebellum.


The different reasons for craniocervical instability to occur might include:

1.Ehlers-danlos Syndrome – This is the syndrome that affects the connective tissues in the body. This condition loosens the ligaments and muscles that hold the parts of the body. It is one of the primary reasons that might lead to craniocervical instability. It is estimated that 1 in 15 people suffering from Ehlers-Danlons syndrome will develop craniocervical instability.

2.Physical Trauma – Any form of physical injuries like accidents, neck injury, or blow to the head that affects the connecting nerves or ligaments can lead to the development of craniocervical instability.

3.Neoplasms – Abnormal growth of cells(tumors) that do not promote the growth of other cells are called neoplasms. Conditions like a bone cyst or blood vessels clot near the cranial nerves might lead to cervical instability.

4.Inflammatory Diseases – Conditions like arthritis that cause swelling or inflammation of the joints might also be one of the reasons for the development of the condition.

5. Congenital– the diseases like downs syndrome or dwarfism that are present from the birth might also cause instability in the craniocervical junction.

6.Nerve Dysfunction – repetitive stress or stretching that occurs on the craniocervical nerves might lead to instability.

7. Cranial Settling – It is the condition when the skull sinks downward on the spine, causing pressure on the surrounding nerves and muscles. The pressure exerted might lead to instability in the cervical region.

8.Retro Flexed Odontoid – Misaligned odontoid bone can be caused due to loose ligaments that push backward, which in turn compresses the brain stem causing instability.

Craniocervical instability can be identified with signs such as severe headaches, pressure headaches, neck pain, facial pain, muscle weakness, sleep apnea, and many more.

Usually, the condition is diagnosed using MRI and CT scans or by Invasive Cervical Traction. The most common treatment method is to perform a craniocervical fusion.

For any neurological related problems, contact Dr.Shyam Sundar K, One of the leading neurologists based in Chennai.

What Are The Warning Signs Of The Brain Tumor?

The abnormal cells that are either benign or malignant developed in and around the brain are known as brain tumors. They are around 130 different types of brain tumors that might develop in the brain or spread from other parts of the body. It is estimated that more than 500 new cases of brain tumors are diagnosed worldwide every day, and around 2500 Indian kids suffer from the disease every year. Unlike before the survival rate of people with brain tumors has increased drastically due to the early identification of symptoms and improvised treatment procedures. 
brain tumor treatment in chennai
The effectiveness of the treatment and eradication of the disease hugely relies on how early the symptoms can be identified. The symptoms of brain tumors can be general or specific.

General Symptoms

These are the symptoms that are caused due to the pressure put by the tumor on the brain or spinal cord. The symptoms might include

Headaches – This is the common sign of brain tumor that more than 50% of people experience. The severity of the pains varies as the day progress, but your head badly hurts during the morning.

Seizures – This is often the first sign of brain tumors that are caused due to the tumor's interference with the brain's electrical activities.

Clumsiness And Numbness – Fumbling with keys, problem while speaking and swallowing, losing feeling in any part of the body can be related to tumors in the brain.

Memory Loss And Confusion - Getting confused over small activities, unable to concentrate, and have issues remembering things.

Fatigue And Nausea – Often, people feel exhausted and sleep for long hours and feel irritability and heaviness in their limbs. Nausea is caused due to the hormonal imbalance caused by the tumor.

Specific Symptoms

Based on these symptoms, the exact location of a tumor in the brain can be pinpointed. Based on the location the signs caused by the tumor include and not limited to

Vision Problems – If individuals are experiencing a problem with their vision, tumors can be located either in the optic nerve, pituitary gland, or temporal lobe.

Speech And Writing Problem - the tumor can be located either in part of the cerebrum, cerebellum, or temporal lobe.

Balance Issues – The tumor can be located at the base of the brain or in the cerebellum.

Hearing Problem
– The location of the tumor can be either near cranial nerves or temporal lobe.

Facial Weakness Or Numbness – The tumor can be present near the brain stem.

The above signs and symptoms need not necessarily confirm the presence of tumors but can guide us in getting an immediate diagnosis. Only an expert doctor can confirm the presence of tumors after a physical examination and diagnostic tests.

Overcome the fear of brain tumors by getting a proper diagnosis and effective treatment from DR.SHYAM SUNDAR K, an expert neurosurgeon who has an impeccable record of handling all the tumor and stroke related cases.

What Are Brain Lesions And How Harmful Are They?

What are Brain Lesions?


 A brain lesion is damage or destruction to any part of the brain. It may be due to trauma or any other disease that can cause inflammation, malfunction, or destruction of brain cells or brain tissue. A lesion may be developed only in one part of the brain, or it may be widespread.

brain lesion treatment chennai

The initial damage may be so small that it may not produce any initial symptoms. However, as the condition progresses over time, it creates noticeable physical and mental changes.


What Causes Brain Lesions? 


  • Aging.
  • Family history of brain lesions.
  • Vascular conditions.
  • Trauma to the brain.
  • Infections.
  • Primary tumors or metastatic tumors
  • Autoimmune diseases
  • Exposure to radiation or certain chemicals
  • Toxins, such as excessive amounts of alcohol or cigarette smoke, in the body.
  • Poor diet

What are the different types of Brain Lesions? 


  • Traumatic: gunshot wound to the brain
  • Infectious: meningitis
  • Malignant (cancerous): glioma
  • Benign (non-cancerous): meningioma
  • Vascular: stroke
  • Genetic: neurofibromatosis
  • Immune: multiple sclerosis
  • Plaques (deposits of substances in brain tissue): Alzheimer's disease
  • Brain cell death or malfunction: Parkinson's disease
  • Ionizing radiation: radiation exposure leading to the death of healthy brain tissue

What are the Symptoms?


Depending on the type, size, and location of the lesion symptoms may change. Some of the common symptoms of brain lesion are:
  • Headaches
  • Neck pain or stiffness
  • Nausea, vomiting, and lack of appetite
  • Vision changes or eye pain
  • Change in behavior and concentration
  • Memory loss or confusion
  • Seizures
  • Fever
  • Difficulty moving

How are Brain Lesions Diagnosed?


Most brain lesions are not diagnosed until after symptoms appear. Often a brain lesion is initially diagnosed by an internist or a neurologist. Expert neurosurgeons like Dr. Syam Sundar, help diagnose and offer treatment options for each patient depending on the severity of the condition.

The doctor will examine the patient's symptoms and medical history. During the physical examination the doctor may touch the patient's skin with hot, cold or vibrating objects, and also may pinch the patient to check for the feeling of pain, to find the location of the lesion. The doctor may recommend additional tests to assess the condition further, which include: 
  • Computed tomography scan (CT or CAT)
  • Magnetic resonance imaging (MRI)

 What are the Treatments?


Treatment for brain lesions varies in each case depending on the type of lesion, its location, and cause. Common approaches include: 
  • Surgery to remove the lesions that are caused by a brain tumor.
  • Chemotherapy and radiation therapy for cancerous lesions.
  • Medication to fight infections, such as antibiotics or other antimicrobial drugs.
  • Medication to calm the immune system or change the immune system's response. 

Can Brain Lesions be prevented?


Many brain lesions are neither preventable nor predictable. However, some guidelines for health maintenance may help prevent some types of brain lesions, such as:
  • To quit smoking.
  • To Control high blood pressure, high cholesterol, and diabetes.
  • Always wear a helmet when participating in activities where the head is exposed to danger.
  • To avoid radiation and environmental toxins.
