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.

Brain Tumors: Types, Symptoms, Diagnosis, and Treatment

One of the common ailments in the elderly people is the Parkinson s. A progressive disorder, when left untreated, results in worsening of the symptoms. Hence, it is essential to understand the treatment options available to manage the condition effectively. You may be suggested surgical therapies if medication is not effective enough to treat the symptoms.

Surgical treatment options can be beneficial for patients who are suffering from symptoms, but they do not help with treating the disease. In the past, surgical methods like Thalamotomy and Pallidotomy were used to destroy brain cells that contributed to the symptoms. While these methods are still used, they are very rare and situational.

Deep Brain Stimulation (DBS), an FDA-approved procedure, has become much more popular as it is much safer and does not involve invasive surgery. Instead of destroying brain cells like traditional methods, DBS involves sending electric pulses to the affected brain cells to reduce the symptoms. It is not a treatment procedure, but a means of bringing down the severity of Parkinson s to allow better and more comfortable treatment.

Deep Brain Simulation   Who are the right candidates?
Deep Brain Simulation is commonly used for Parkinson  s disease, but it is not recommended for everyone. It is a preferred method of treatment for people who have had Parkinson s for at least four years but have complications which include long periods of time where medications do not work, or symptoms return, uncontrolled and involuntary movements or the freezing/stiffness in the body.

Deep Brain Simulation is not recommended for those who have Dementia as it can lead to memory problems. The general rule of thumb that neurosurgeons follow is that Deep Brain Simulation can help with symptoms that do not get better with medication. DBS can help reduce medication requirements for patients as well as reduce the side effects that may occur due to medication.

Disorder specialists and neurosurgeons can conduct tests to determine if DBS is going to be effective for a patient before going ahead with such a procedure. An extensive assessment is necessary to understand the symptoms, the effect of Parkinson's drugs and also brain imaging is done. All of the expected benefits are then evaluated for the patients, and if the procedure can help alleviate the symptoms, DBS is given a green signal by neurosurgeons and patients can undergo the procedure.

How Does Deep Brain Simulation Work?
Deep Brain Simulation is a very complex procedure. Brain cells communicate with the rest of the body through electric signal, and these become irregular and do not work properly when affected by Parkinson's. DBS smoothens the functioning of these brain cells and reduces symptoms through electric pulses through the implantation of a medical device known as neurostimulator which is also referred as brain pacemaker.

But, as with any treatment procedure, DBS has potential risks and side effects, hence discuss with neurosurgeon thoroughly to access the suitability.

Adopting Deep Brain Stimulation For Parkinson's disease

The brain contains numerous nerve cells which help in its normal functioning. Epilepsy or seizures occur when there is a disruption in the activity of the nerve cells in the brain. A neurological disorder of the CNS (Central Nervous System), epilepsy can affect all and sundry, irrespective of their age, sex and ethnicity. However, children and aged people (above 60 years) are more susceptible to the condition. A study suggests approximately 10 million people in India suffer from epilepsy.

Types of Epilepsy
Based on the activity of the brain that causes an epileptic attack, Epilepsy can be of two types - Focal or Generalized
Focal Epilepsy: An epileptic attack triggered by unusual activities restricted to a particular area of the brain.

In some cases, focal epilepsy may result in unconsciousness. A person may also lose awareness and become unresponsive (keeps staring into space), a condition termed as Focal Dyscognitive Seizures. A person with this condition may behave strange, such as walking in circles, chewing or rubbing their hands.
In another type of focal epilepsy known as Focal seizures without loss of consciousness, a person does not lose consciousness. In such cases, there may be sudden and involuntary jerking of the arms or the legs. There may also be dizziness or a tingling sensation.
Generalized Epilepsy: Here, the seizures or epilepsy result from unusual activities throughout the brain. Generalized epilepsy, may, in turn, be of the following subtypes

Tonic seizures: This affects the muscles of the legs, arms, or the back, causing them to stiffen and tighten up.
Atonic seizures: Here, a person may suddenly fall down due to loss of muscle control. The condition is also known as Drop Seizures.
Absence seizures: Mostly affecting children, the affected person may lose awareness (temporary) and behave strangely such as staring into spacing, smacking their lips, or blinking their eyes continuously.
Clonic seizures: They are characterized by sudden and continuous jerking movements of the arms, face, and neck muscles.
Tonic-clonic seizures: Here, a person may suddenly lose consciousness. There are violent shaking and stiffening of the body. Some people may even be seen biting their tongue.
Myoclonic seizures: In this arms, and legs of a person suddenly twitches and jerks.

What triggers an Epilepsy?
Epilepsy may be an outcome of the following factors

Medical conditions such as stroke or even brain tumors may affect the normal activities of the brain, thereby resulting in epilepsy. Diseases such as Viral Encephalitis, AIDS or Meningitis act also act as a trigger, accelerating the chances of epilepsy.
Developmental disorders such as Neurofibromatosis or Autism can also trigger epilepsy.
In some cases, epilepsy may be a genetic predisposition. Thus, a person with a family history of epilepsy may suffer from the condition.
Epilepsy may also be an outcome of a prenatal brain injury due to oxygen deficiency or an infection to the mother.
People with dementia may also suffer from an epileptic attack.

Epilepsy - Know The Most Common Types!

Epilepsy is a form of chronic disorder and it is characterized by recurrent seizures. The episodes of epileptic seizures may differ from person to person. These seizures could be a result of a genetic disorder or a result of trauma or stroke. During a seizure, a patient may also experience symptoms of neurological disorders and sometimes lose consciousness.

Medical help for epilepsy
Epilepsy itself cannot be cured using medication, but proper medicines help in eliminating recurrent seizures. These medicines stabilize the electrical activity within the brain preventing seizures.

How effective is the medication for epilepsy?
The success of controlling seizures using medicines depends on the type and severity of epilepsy. Medicines for epilepsy are usually very effective and may fully keep seizures under control. However, controlling seizures caused due to brain problems may be more difficult. Usually, epilepsy medicines can control seizures for a long period of time when they are taken regularly.

When is medical help needed?
The decision about when to start medicines for epilepsy is a tricky one. This is because a first seizure cannot confirm whether a person has an on-going epilepsy problem. A second seizure may occur after many years or may not happen at all. Prediction of seizures is also quite difficult.

The severity of seizures also indicates when to start medicines for treatment. In case a first seizure is quite severe, medication should be started at once. Some people have very mild seizures even though they may be recurring in nature, and medication can be avoided in this situation.

The decision of starting medication will vary from case to case and in most cases, medications may be prudent after the first seizure itself. You should always consult a doctor to know when you need to start taking medicines to treat the condition.

For making the most out of the medicines to control seizures, you should follow certain steps:

You must take medications exactly as your doctor has prescribed.
Before switching to generic versions of your medicines or before taking other prescribed medicines, you must consult your doctor.
You should never stop taking the medicines.
In case you experience enhanced depression, mood swings and suicidal thoughts, you should talk to your doctor immediately.
In case you have the migraine, you should let your doctor know so that he can prescribe you anti-epileptic medicines, which also prevent migraines.
Medicines cannot treat the underlying cause of epilepsy, but these help in controlling seizures and this is the most common symptom of epilepsy. Medication should be started at a proper time and must be continued without stopping.

Epilepsy - When To Seek Medical Help?

Sleep is the normal physiological process of our body which is as important as respiration and digestion. Sleep is vital for maintaining our physical and mental health. Normal adults require 8 hours of sleep every day, whereas it 14 to 15 hours of sleep is recommended for for infants and toddlers.

What are the different stages of Sleep

Every human has a natural circadian clock in their body, which is responsible for maintaining our sleep - wake homeostasis. The different stages of sleep include REM and NREM that is rapid eye movement sleep and non rapid eye movement sleep respectively. REM is the deep sleep stage in which it is very difficult to wake up the person as this stage includes the sensory inhibition and all voluntary muscles along with almost all interactions with the surroundings are inhibited. Therefore, a person s physical stress and tiredness also gets relieved during this stage of sleep. NREM sleep is the stage between REM and awakening and here the person may have sensory connection with his or her surroundings, but may not respond.

Sleep and its benefits
Sleep and stress have a very strong connection with each other. The best way to relieve stress and any other mental disturbance is sleep. It is essential to have knowledge about sleep psychiatry for almost all physicians as they face many sleep deprived patients in their day to day practice.

    Sleep is not only responsible for relieving mental stress and depression, but has other benefits as well
    Sleep is also essential for the normal physiological growth in early infancy and it is vital for development of normal alertness, attention and knowledge
    It also relaxes our voluntary muscles and thereby, relieves us from physical stress
    Sleep disturbance may also aggravate diseases in our body. Sleep is also the state of recovery and healing.

Sleep psychiatry also insist on meditation and ensures that people have normal pattern of sleep, in order to maintain the mental health of the person in a normal state.

Sleep Pyschiatry: Its Stages and Benefits

Sleep is one such time when people usually are expected to lie down still and get rest. However, we have all heard of sleepwalking, a condition where a person walks during the sleep. Though it may sound strange, there is a deeper explanation for it both from a causative point of view and from managing it.

Things you should know?

Sleepwalking happens when a person moves back from a deep sleep to a light sleep or awakening state.
The person who is sleepwalking is usually not aware of it.
Activities may range from simply getting up and sitting up in bed to walking around the room. They could also open the door and walk out to the neighbourhood. Moving furniture, changing dresses or driving a car, may also be some of the actions Most of these activities happens completely without their knowledge.
Mostly happens in children up to the age of 12, but can be seen in adults also, where it assumes a more severe form.
The person who is sleepwalking has a fixed stare with glassy eyes. They may appear dazed and lost when they are awakened.
They may not respond when they are actually sleepwalking, or respond very slowly
They can be brought back to bed and put back to sleep without being disturbed. Most children would go back to sleeping when this is done
Though the parents can be very worried when they see children sleepwalking, reassurance is required, as it usually disappears as they cross teenage.
There could be chances of small injury like tripping or fall during the sleepwalking episode
Sleepwalkers may be more restless compared to other children during their waking hours
Bedwetting is also quite common in children who sleepwalk
Causes

Inappropriate sleep pattern with lack of sleep for prolonged periods is one of the main reasons for sleepwalking
Stress
Excessive drinking
Medical conditions like heart rhythm problems, acidity, gastric reflux, and seizures
Psychiatric conditions like panic attacks and post-traumatic stress disorder can also lead to sleepwalking
Management

For a parent to see their child walking around in their sleep can be quite disturbing.
Reassurance is required stating that it is just a temporary phase and will not stay beyond the teenage years
Most people do not require any intervention unless accompanied by severe symptoms like going out of the house or driving
Once established, it is advisable to avoid by not drinking too much alcohol, avoiding stress and anxiety and taking precautions like extra-secure locks to prevent sleepwalking and/or other side effects.
