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

Sleep is known to most as a period of rest and relaxation, but there are multiple disorders which are associated with sleep too. Hypersomnolence or hypersomnia is one of the most common sleep disorders. This is characterised by excessive daytime sleepiness and prolonged periods of sleep at night. They wake up fresh in the morning, but can easily go back to sleep any time of the day without feeling strained or tired. There is again no freshness associated upon waking up. Funny as it may sound, they can doze off even during a meal or in the middle of a conversation.

Causes: This condition is most common in men and in the early adolescent days.

There is no underlying cause that has been identified, though there is a genetic predisposition.
People with history of head trauma are more affected
People with anxiety, depression, bipolar disorders, epilepsy, and other mental disorders are also more likely to be affected
People with sleep apnea often are hypersomnolence
Restless legs syndrome, narcolepsy
Neurodegenerative disorders like Parkinson s and Alzheimer s tend to sleep more.
Symptoms:

Sleeping for longer hours at night time
Excessively sleepy during daytime
Able to doze off anytime during the day
Inappropriate and involuntary sleeping pattern
Having difficulty getting out of bed after waking up, even after prolonged sleep
Feeling of disorientation
Feeling agitated, anxious, lethargic, and irritated
Impaired cognition and memory
All these lead to extreme state of drowsiness
Increased tendency for hallucinations
Reduced appetite and even weight loss in some people
There is restlessness, reduced pace of thinking and speaking
Overall reduced energy levels
Social interactions are affected including work life, social functions, etc.
Diagnostic criteria:

If a person happens to sleep more at night or falls asleep during the day easily for more than 3 times a week, it is usually concerning.
The added feature of no tiring physical activity can also lead to suspicion
In acute cases, these symptoms are present for at least a month and in chronic cases, it could be seen for up to 3 months
It cannot be explained by lack of sleep on a regular basis
One or more of the above conditions could be present, which can help in making the diagnosis
Treatment:
Most cases of hypersomnia would need treatment only to improve their energy levels and improve the quality of life. Very often, treating the underlying condition can lead to improvement of hypersomnia. The tired, lethargic, restless feeling affects the overall performance of a person, leaving them with a lowered self-esteem. Brain stimulating drugs like amphetamines are used to improve daytime alertness and also reduce sleepy feeling during the day.


Hypersomnolence - How It Can Be Managed?

Diagnosing dementia can be more difficult than you can imagine. Medically, the patient needs to have at least two areas of mental functionality impaired to an extent where it interferes with their everyday life. However, diagnosis is just the beginning as treating dementia can be even more challenging. Here is a look at some of the treatment options available for dementia patients.

 Treatment for Dementia
There is often no cure for most forms of dementia. Treatment relies on the management of the condition, to ensure that the progression can be impeded. With proper treatment, patients can live a relatively normal life for a number of years.

Cholinesterase inhibitors- These medications are used for the treatment of Alzheimer s disease. They are chemical agents that boost the memory and judgment of the patient. The same is also an effective medication for those suffering from Parkinson s disease and Lewy body dementia.
Therapy- Making small changes to some aspects of life of the patient can often yield good results. For instance, clearing the clutter and noise in the house can be an effective way of helping dementia patients deal with their condition. Similarly, creating a safe environment at home with little chance of severe accidents, will ensure the safety of the patient.
Stress in caregivers of dementia patients
Dementia patients need to be cared for, ideally by a close family member such as a spouse. However, these caregivers undergo a lot of stress while providing support to the patient. For instance, Alzheimer s patients often do not recognize their caregiver who may also be their spouse. Here are some burdens that caregivers have to deal with.

Anger- The sense of fury towards the patient can be strong after years of providing care. They may also be frustrated with the fact that the affected person is unable to perform simple everyday jobs, such as brushing their teeth or tying their shoelaces.
Anxiety- A sense of hopelessness regarding the future is common. It is also the fear of what new challenges the next day might bring.
Depression- Seeing their loved one s mental state deteriorating with each passing day can be difficult to handle and pushes some caregivers into depression.
With such continuous emotional and physical stress, caregivers often fall sick themselves. This is why it is necessary to maintain a bright outlook and remember that a dementia patient can only get well if they have the full support of the caregiver.

Treating Dementia - Things You Should Know!

Both schizophrenia and autism are considered to be neurological disorders resulting from atypical neural development, occurring due to a variety of causes. Both these disorders have a genetic predisposition that may be due to environmental factors. However, there are a few basic differences between the two disease conditions.

Autism is also known as Autism Spectrum Disorder (ASD), is a neurodevelopmental disorder characterized by a spectrum of abnormal behaviour. They include persistent deficits in social communication and interaction, along with restricted and repetitive patterns of behaviour, interests or activities.

Signs of autism in babies

By 6 months - No social smiles or other warm, joyful expressions; limited to no eye contact
By 9 months - No sharing of vocal sounds
By 12 months - No babbling or use of gestures to communicate; not responding to one s name when called
By 16 months - No use of words
By 24 months - No meaningful or two-word phrases
Signs of autism at any age

Avoids eye contact and wants to be alone
Finds it difficult to understand other people s feelings
Speaks very less or has delayed language development
Echolalia - Repeats words or phrases
Cannot accept change in routine or surroundings
Performs repetitive behaviours like flapping or rocking
Has restricted interests and hobbies
Reacts unusually intense to sounds, smells, tastes, lights, colours etc.
Schizophrenia
Schizophrenia is a neuropsychiatric disorder that begins during late adolescence and early adulthood. It is characterized by delusions, hallucinations, disorganized speech and behavioural changes that cause social and occupational dysfunctions.

Signs of Schizophrenia

The symptoms of schizophrenia are usually observed between ages 16 and 30, such as e.g. delusions, hallucinations, thought disorders, movement disorders etc.
Delusions are false beliefs of the patient that may take many forms like delusions of persecution or grandeur. You may feel somebody is controlling you or may think you have extraordinary powers and abilities.
Hallucinations are when the patient hears voices more than seeing, feeling, tasting or smelling random things, which are not actually there.
Thought disorders are when the person jumps from one subject to another for no logical reason.
Some negative symptoms i.e. these are symptoms which are normally present in a healthy individual, but are absent in a schizophrenic patient. E.g. absence of facial expressions, lack of motivation etc.
Cognitive symptoms affect the individual s thought process. They can be positive or negative based on their expression. E.g. poor  executive functioning  which deals with the ability to understand information and make decisions using them, finding it difficult to focus etc.
Although both Autsim spectrum disorder and schizophrenia are interlinked in their causes and neurological background, the symptoms for each disorder are different. 
Consult your physician if you happen to observe any of these symptoms in your loved ones.

Autism & Schizophrenia - What Is The Difference?

Parkinson's disease is a neurodegenerative condition that affects your brain cells which produce dopamine and thus hampering all kinds of motor functioning and other emotional responses. After the disease is diagnosed, medication and therapy can help to provide relief from the symptoms to a large extent but a permanent cure is not possible.

Causes:

The disorder does not have a definite set of causes. A small percentage of the cases have been related to hereditary factors and others have a range of environmental causes associated with them.

1. Genetic factors:

Specific gene mutations and gene variations have been proved to cause Parkinson's, such as SNCA, PARK2, PARK7, PINK1 and LRRK2. These make or recycle proteins which are linked to the disease.

Research shows that men are at a 1.75 times greater risk of developing the condition than women are. Also, age plays a role with most cases occurring after the age of 60.

2. Environmental factors:

Regular exposure to inorganic insecticides, pesticides, herbicides and heavy metals or other toxins may cause the disorder. In rare cases, Parkinson's disease occurs in the aftermath of a severe head injury or immune disorders.

Symptoms:

The symptoms can be classified into two broad categories-

1. Motor symptoms:

The hand tremors when in resting position
The grip loosens
Walking slows down
Facial muscles freeze partially
Speech is slurred
Balance is disturbed
Swallowing is painful
Urination is abnormally frequent
Dementia-like symptoms are seen
There is involuntary twitching of the fingers and toes
Repetition of the same movement in quick succession is nearly impossible
2. Non-motor symptoms:

Dental problems
Vision impairment
Skin disorders
Panic attacks
Excessive secretion of saliva
Extreme weight loss or gain
Sexual problems
Loss of sense of smell
Lowering of the pitch of the voice
Fatigue

Causes and Symptoms of Parkinson's Disease

A tumor is an uncontrolled and abnormal growth of cells. A brain tumor is thus an abnormal growth and multiplication of cells in the brain. The cell growth can also be in areas adjacent to the brain. The brain tumor may

Have its origin in the brain (Primary brain tumor), or
Its origin may be in some other parts or organs of the body, which gradually spreads to the brain (Secondary/metastatic brain tumor).
Not all brain tumors are harmful and life threatening.

Brain tumors that exist as noncancerous cell growths are known as Benign brain tumors. Benign brain tumors seldom pose any threat to life.

Brain tumors that are cancerous and, thus, harmful, are known as Malignant brain tumors.

Do not neglect any brain tumors (malignant or not). It is better to be safe than to be sorry.

Types of Primary brain tumors:

Based on its cell of origin, primary brain tumors (benign as well as malignant) may be of the following types:

Meningiomas: Brain tumors that originate from the meninges (the membranes that cover the brain and the spinal cord). Meningiomas are seldom malignant.
Acoustic Neuromas: A noncancerous cell growth that has its origin in the vestibulocochlear nerve (the eighth cranial nerve). This nerve connects the brain with the inner ear.
Gliomas: Here, the tumor has its origin in the brain and the spinal cord (glial cells). This type of brain tumors, in most cases (~80%), are malignant.
Primitive Neuroectodermal Tumors (PNETs): Extremely rare, PNETs are malignant tumors that develop in the embryonic cells in the brain.
Medulloblastomas: Medulloblastomas is a malignant brain tumor that mostly affects children. It originates in the cerebellum (lower part of the brain).
Craniopharyngiomas: A benign brain tumor that has its origin near the pituitary gland (base of the brain). Craniopharyngiomas are common in children.
Probability of a secondary brain tumor are more in people who have had;

Kidney cancer
Breast cancer
Lung cancer
Colon cancer
Melanoma
Symptoms:

The symptoms of brain tumor include:

Chronic and regular headaches.
A change in the headache pattern.
Seizures.
A person may experience vision problems (Peripheral vision may be affected, double or blurred vision).
There may be difficulty in hearing.
Nausea and vomiting.
Behavioral and speech problems.
An arm or a leg may lose sensation.
A person has difficulty with balance.
Diagnosis and Treatment:
Though brain tumor can affect anyone and everyone, its chances are higher in

People who are more exposed to ionizing radiation. People having undergone a radiation therapy are equally vulnerable.
Children as well as older people.
People having a family history of brain tumors.
The diagnosis includes;

An imaging test like the MRI, CT scan and PET (Positron Emission Tomography).
Biopsy, whereby samples of the abnormal tissue is collected and examined.
Neurological examination.
Treatment:

Surgery is an effective treatment for brain tumors.
One can also opt for:

Radiations, whereby the abnormal tumor cells are destroyed using protons and x-rays (high-energy beams).
Chemotherapy: In this treatment, the tumor cells are destroyed using strong drugs (taken orally or intravenously).
Radiosurgery.
Targeted drug therapy: This treatment blocks the abnormalities that are characteristically present only in the cancer cells.
