Brain cancer is a disease of the brain in which cancer cells (malignant cells) arise in the brain tissue. Cancer cells grow to form a mass of cancer tissue (tumor) that interferes with brain functions such as muscle control, sensation, memory, and other normal body functions. Tumors composed of cancer cells are called malignant tumors, and those composed of mainly non-cancerous cells are called benign tumors. Cancer cells that develop from brain tissue are called primary brain tumors while tumors that spread from other body sites to the brain are termed metastatic or secondary brain tumors.

Prologue:

Brain cancer is actually the abnormal growth and uncontrolled growth of the cancer cells in the brain,that forms a tumor in the brain.Tumours can be either benign or malignant.

Benign brain tumours are abnormal collections of cells that reproduce slowly and usually remain separate from the surrounding normal brain.

Malignant tumours reproduce and grow quickly. Their borders are hard to distinguish from the normal brain around them.

Symptoms:

There are few early symptoms of brain cancer, but as the tumour grows within the confines of the skull, it causes increased intracranial pressure and exerts pressure on the brain, causing signs to develop.

Brain cancer symptoms and signs are varied and depend on the area of the brain involved, but can include:

Headaches.

Seizures.

Nausea and vomiting, which, CANSA reports, may be worse in the morning or after a sudden position change.

Difficulty walking or clumsiness.

Vision changes.

Changes in alertness.

Behavioural impairment.

Causes:

Brain cancer occurs when there is an uncontrolled growth of cancer cells in the brain that form a malignant brain tumor. The underlying cause of primary brain cancer, cancer that begins in the brain, is not known. Secondary brain cancer is caused by a cancer of another organ in the body, such as the breast, prostate, kidney, skin, or bone, that has spread to the brain.

What are the risk factors for brain cancer?

Certain inherited conditions, including neurofibromatosis, Von Hippel-Lindau syndrome, Li-Fraumeni syndrome, and Turcot syndrome

Personal history of cancer or family history of brain cancer

Impaired immune system

Radiation therapy of the head

Treatments Options:

Treatment

Surgery is the main form of treatment for brain tumors that lie within the membranes covering the brain or in parts of the brain that can be removed without damaging critical neurological functions. The goal is to remove the entire tumor, whenever possible, as a tumor may recur if any tumor cells are left behind. Radiation therapy and chemotherapy are generally used as secondary treatment for tumors that cannot be cured through surgery alone.

Stereotactic radiosurgery

Stereotactic radiosurgery is a treatment option that delivers a high concentration of radiation directly to the tumor in order to stop its growth, while delivering only a minimal dose of radiation to the surrounding tissue. Unlike conventional surgery, stereotactic radiosurgery does not require making an incision to remove the tumor. It can be especially effective in patients with many small metastatic brain tumors.

Brain Cancer

Grading of brain cancer is entirely different as compared to the staging of other cancers in the body. Cancer in the breast, lung, colon etc. are staged depending on the possible spread, location of a tumor and lymph node involvement etc. However, brain tumors are graded based on the aggressiveness of the tumor cells under a microscope. The resect ability and the grade of the tumor cells guide a doctor on the treatment decisions. The decision of a brain surgery depends on factors such as the location, spread of a tumour and the general health of the patient.

Types of Brain Tumor Grading:

Grade 1 tumor- These sets of tumors are medically known as the juvenile pilocytic astrocytoma and subependymoma. They are slow growing and non-invasive. There is a likelihood of the patient getting cured with surgery.
Grade 2 tumor- These are brain tumors that do not possess dead cells as part of the tumour. But, they do portray a lot of abnormal cells. Tumors of this type can be categorized under oligodendroglioma, astrocytoma, and ependymoma.
Grade 3 tumor- Tumors of this type are graded based on the cell type of the cancer cells. For instance, an anaplastic astrocytoma is a grade 3 tumor that has no dead cells but possesses dividing cells. In contrast, anaplastic ependymoma and anaplastic oligodendroglioma are grade 3 tumor cells that have dead cells in them.
Grade 4 tumor- Tumors of this type are referred to as glioblastoma. The tumor cells are actively dividing, the growth of blood vessels is witnessed and areas of dead tissue keep expanding.

Treatment options:
Surgery- If the location of a brain tumor is such that it is accessible to a surgeon, the latter goes ahead and removes most of the tumor if not the whole. If, however, the brain tumor cells are placed very near to the surrounding very sensitive brain tissues, a doctor might remove a small portion of the tumor to curb its growth.
Radiation Therapy- This mode of treatment uses high energy X-ray beams to kill targeted cells of the brain. External beam radiation usually targets a small area of the brain. A whole brain radiation, on the other hand, is usually employed when a tumor has spread to most parts of the brain. Radiotherapy is now so evolved that it is highly targeted to tutor cells that kills cancer and spares normal brain .
Chemotherapy- Chemotherapy employs drugs to kill cancer cells. Chemotherapy can either be taken in the form of an IV or in the form of pills. The dosage of chemotherapy is decided based on the concentration of cancer cells, spread frequency, platelet count of the patient etc. The most common chemotherapy drug that is prescribed by doctors to fight cancer cells is temozolomide.

How Serious Are Seizures in Children

During a febrile seizure, the body of a child may convulse, shake and contract, the eyes may roll, and he or she may moan or become unconscious. This type of seizure is usually for a few minutes, but in rare cases can last up to 15 minutes.

Febrile seizures stop on their own while the fever persists until treated. While some children may feel sleepy afterwards, others do not have lasting effects.

Seizures in toddlers may be caused due to the following factors

Epilepsy

Epilepsy is defined categorically as two or more seizures without any acute cause. Epilepsy can occur at any age, but it is usually diagnosed in infants and young children.

Body temperature

Body temperature may indicate a crisis in small children. High body temperatures or low body temperature can cause seizures in a toddler. These types of seizures occur only once or twice in children two years or younger, often after an illness. This type of seizure due to the fortification of the body temperature is considered a febrile convulsion.

Dehydration

Febrile seizures can also occur due to dehydration. Dehydration is a direct result of a previous illness that included sweating and fever.

Physical condition

A child who is in poor physical condition can also be prone to seizures. Malnutrition or a body weakened by disease or illness makes small children more susceptible to crises.

Family History

Family history can play a role in toddlers or children with seizures. If a family member suffered from the tendency or had convulsions, particularly febrile seizures as a child, this trait can be inherited.

Treating febrile seizures

If your child has a febrile seizure, stay calm and:

Make sure your child is in a safe place and does not fall or hit something hard
Place your child on his side to prevent choking
Watch for signs of breathing difficulties, including any colour change in the face of your child
If the seizure lasts more than a few minutes or your child turns blue, it may be a more serious type of seizure; connect with doctors immediately

Febrile seizures can be frightening to witness, but remember they are fairly common and are not usually a symptom of a serious disease, and in most cases does not lead to other health problems.

What causes hearing loss? + How to ensure you can help it as you age

The partial or total inability to hear is known as hearing impairment or hearing loss. It can be present at birth, or develop later in life.

There are a number of factors, which may cause hearing loss

1. Age - Age is the biggest factor when it comes to the loss of hearing, and you may lose the ability to hear as you age. This condition is known as presbycusis. It becomes difficult to understand high-frequency sounds like that of a child or a woman when you get old.

2. Noise - When you are exposed to loud noises for a prolonged period of time, it damages your ears. This leads to loss of hearing. 5% of the total population of the world is affected by noise (the degree of suffering varies). It may be a result of continuous exposure to loud music or a sudden exposure to a loud noise like an explosion.

3. Hereditary disorders - Hearing disorder may be inherited by the dominant or recessive genes of parents in the child. 70-80% of these cases inherit from the recessive genes, whereas 20-25% inherit hearing loss from the dominant genes.

4. Trauma - Serious injuries of the head/ears may cause loss of hearing, which may be either temporary or permanent. When damage is caused to the brain, the brain fails to process the message conveyed by the ears. So even if the ears are totally functional, a person may face the problem in hearing.

5. Perinatal problems - The ototoxic effects on the fetus due to excess intake of alcohol during pregnancy lead to hearing the loss in about 64% of the infants born to alcoholic mothers.

Also, premature birth can be associated with hearing loss due to high risk of being exposed to noise in neonatal units.

Knowing about the causes of hearing loss can lead you a step closer to preventing this disorder as you age.

Here are some useful tips that can help prevent hearing loss:

1. Be more aware - You should be diligent and aware of the situations, which may risk your hearing ability and should try to avoid such situations as much as possible. Limit your exposure to sources of hazardous noises like firearms, firecrackers, concerts and clubs.

2. Take precautionary measures - If your occupation calls for working at an environment of loud noises, use earplugs or earmuffs to block out the excessive noise. Also, make sure that you work in a place where employers take all the necessary measures of noise control under the federal or state regulations.

3. Monitor your use of gadgets - Monitor and control the use of hearing devices, and try to reduce the use of headphones/ earphones as much as possible.

Nobody knows the exact cause of autism. All medical science knows is that it s a complex neurological disorder which is detected within the first three years of life and is caused due to structural changes in the brain. Autism causes a number of symptoms which grade from mild to moderate to severe, like-

Difficulty in communication and social interaction
Language impairment
Preoccupation with fantasies
Repetitive acts (echolalia)
Excessive possessiveness to certain objects
Intellectual impairment
Over-sensitivity or under-sensitivity to pain
Developmental problems
Causes
Genetic predisposition is the most common cause of autism. Exposure to environmental toxins is the other. Other causes are use of certain drugs during pregnancy, vaccinations etc.

Diagnosis
Diagnosis of autism can only be done by clinical evaluation as there are no laboratory tests for it. The psychiatrist prepares a detailed developmental case history of the child before arriving at a diagnosis.
There are a number of Autism screening tests to diagnose autism as well. One thing to always follow is to go to a psychologist who has a history of treatment of autistic disorders.

Diet
Theories are emerging that autism may be caused by a super sensitive child s response to foods like gluten found in grains and casein, a protein found in milk. These transform into substances that act like opiates in the child s body.

These drug-like substances alter the child s behaviour, his perceptions, and his responses to his environment. Recent research has found chemicals with opiate activity in the urine of a significant number of children with autism.

Autistic children have shown mild to dramatic improvements in speech, behaviour after going on a gluten-free, casein-free (GFCF) diet.

Some of the foods that can be eaten on GFCF diet include rice, quinoa, potato, buckwheat flour, soy, amaranth, corn, fruits, vegetables, beans, tapioca, meat, poultry, fish, shellfish, nuts, eggs, and sorghum, among others.

Homoeopathic treatment of Autism:

The homoeopath carries out a detailed study of the family history of serious diseases which are linked to the development of autism in his patient.
The genetic evaluation of the patient is followed by case analysis which takes into account impaired functions in the patient like repetitive behaviour, lack of social skills, speech issues etc.
The homoeopathic medicines indicated for autism are twenty and are usually given in combinations. A homoeopath takes the decision about the exact medicine to be given, its combination with other support medicines, the dose and its repetition based on the case history of the child.
By no means should one try to cure autism by self-medicating on homoeopathic medicines as this can cause deleterious effects.
It usually takes a minimum of six months for some perceptible changes in autistic children. Homoeopathic treatment may have to be continued for over a year if the symptoms of autism are very severe.

A brain tumor can occur at any age and it generally occurs in people in the age group of 40-60 years. The common types of brain tumor are termed as meningioma and gliomas. These supratentorial brain tumors generally occur above the covering of the cerebellum tissue. In children, brain tumors occur at the age of 1-12 years and the most common tumors are ependymomas, astrocytoma and meduloblastomas. Brain tumor is the common cause of death even in children.

Tips to Detecting a Brain Tumor

The general symptoms that are indications of a brain tumor include severe headaches, memory changes, nausea, drowsiness, sleep problems, fatigue and sudden involuntary movements of muscles of an individual. The symptoms can be either specific or generic and the general symptoms are mainly caused by the pressure of the tumor on the brain. The specific symptoms on the other hand are caused when specific parts of the brain does not function properly. Many people even experience loss of control of body functions.

The other problems that are experienced by individuals include changes in the ability to perform daily activities and loss of balance. They find difficulty in hearing, speech and at times are very aggressive. If these symptoms exist, then your doctor would recommend a physical examination and ask about your health history and that of your family.

Tests to Detect Brain Tumor
The tests that are advised by doctors to detect a brain tumor include MRI, neurologic exam, CT scan, biopsy, angiogram and spinal tap.

In the neurologic exam the vision, alertness, hearing, coordination, muscle strength and reflexes are checked by the doctor. The doctor also checks for any swelling in the eyes which can be caused by the pressing of the nerve which connects the brain and the eye.

The CT scan done for detecting brain tumor provides detailed pictures of your head and it is done through an X-ray machine which is connected to a computer. The contrast material is injected into the blood vessel of your hand and abnormal areas can be seen easily.

Biopsy
In this method tissues from the brain are removed and tested for tumor cells. The cells are observed by a pathologist under a microscope mainly to check for abnormal cells. The biopsy method is used to show tissue changes that can further lead to cancer. Brain tumor can be easily diagnosed with this method.

MRI:
Magnetic Resonance Imaging or MRI as it is commonly referred to is of great use as it helps to diagnose brain tumors. In this procedure, a dye is injected through a vein in the arm using which the variances in the tissues of the brain can be identified.
