A stroke, also called cerebrovascular accident (CVA), cerebrovascular insult(CVI), or brain attack, occurs when a part of the brain is deprived of blood flow. When the brain cells are deprived of oxygen they begin to die. When brain cells die, the functions controlled by that part of the brain also stops, which results in different types of disabilities among stroke survivors.

There are two types of strokes

Hemorrhagic
Ischemic stroke
The first is caused when a brain aneurysm or a weak blood vessel bursts. Most of the time, this type of stroke leads to death. The second one happens when a clot blocks the flow of blood to the brain. Patients suffering from stroke suffer from various side-effects, the most common ones being paralysis or loss of feeling in a certain part of the body, problem in understanding or talking and loss of vision in one side. The side-effects start showing up regularly after a person has had a stroke.

In certain conditions, blood flow to a certain part of the brain stops for only some time and hence the body suffers stroke like symptoms which only last a couple of hours before disappearing. This is known as a transient ischemic attack (TIA). Unfortunately, the effects of a stroke can be debilitating and also permanent. Hence its important to know the symptoms of a stroke and rush the patient to a doctor as soon as possible. Sometimes early treatment can save a lot of damage.

The primary symptoms of stroke are as follows:

Confusion and problems with talking and comprehension
Headache along with alteration of consciousness or vomiting
Numbness of the face, arms or legs, especially on one side of the body
Issue with seeing, in one or both eyes
Inability to walk with stability, including disrupted coordination
Problems with the bladder and bowel control
Acute depression
Body temperature fluctuates, and pain worsens with movement
Paralysis on one side of the body along with fatigue
Problem in expressing or controlling emotions
Risk Factors:

Hypertension
Diabetes
Increased Cholesterol
Smoking
Obesity
Sedentary Lifestyle
Diagnosis of stroke

Several tests are carried out to determine the type of stroke acquired. They are:

Physical examination, which involves observing the patient's overall condition.
Blood tests
CT scans
MRI scans
Cerebral angiogram
Echocardiograms
Stroke is a fatal brain disease and can cause permanent damage to your system so its best to check with your doctor to know how you can prevent it.

Brain Stroke - Factors That Can Lead To It!

One of the most debilitating conditions that anyone can experience is migraine. They can severely limit you by affecting your personal and professional life as you are in constant pain. Migraine can manifest in a type of headache with intense pain, an acute sensitivity to light, vomiting and nausea. Often described as a severe throbbing pain in the head, it may stop you from completing regular daily tasks and may delay or postpone your work.

How can migraines be treated?
The exact cause for these debilitating migraine pain hasn't been pointed out yet, but certain triggers such as stress, hormonal changes in the menstrual cycle, sun exposure, bright or flashing lights, among many others have been identified. The first line of defense for you would be to understand and identify what your triggers are. Once that is done, you can try and avoid them. If these still trigger a migraine or are about to trigger one, you can immediately take medications or steps to control it or at least lessen the pain to go through your day. Some of the options you can employ to this effect are mentioned below.

Medications to prevent a migraine attack: The medications mentioned here are specialized treatments and can only be taken after a consultation with a doctor. If you are deemed as a candidate for preventative medication for migraines, then either one or a combination of drugs from the following may be prescribed to you.
Valproate and Topiramate are anti-seizure medications which can be used to prevent migraines.
Propranolol, a type of beta blocker and used for cardio vascular problems, has proven to be very effective in preventing migraines.
Onabotulinumtoxin A or a type of Botox, has shown a lot of promise in preventing migraines and is being slowly rolled out as a proper drug as a treatment option.
Certain antidepressants have also shown to be quite effective in reducing the symptoms of migraines as well.
Medications to relieve pain: Some of the go to medications that help relieve your pain from migraine are mentioned below. Although some of them are OTC (over the counter) drugs, it is best advised that you consult with your doctor for medications which suit you better. The side effects of these medications can be bad and thus, it is not advised to continue them in the long run and to find other means to control pain from migraines. Some of the medications to relieve pain temporarily are:
Triptan is a drug used to treat severe migraines
Caffeine along with Ergotamine can also help dull the pain and deal with it.
Ibuprofen and aspirin and Acetaminophen are common pain killers that you can use
Codeine, which contains opioids are also used to treat this problem.
Metoclopramide and chlorpromazine are two examples of anti-nausea medications as vomiting along with nausea may frequently accompany your migraine.
Always remember that these medications can have strong side effects if not taken properly, therefore do not just pop a pill, consult your physician first and know which one should you take and how frequently. 

Severe Headache - Can it Be Migraine?

Parkinson s disease is a disorder involving the nervous system. It can start with a mere tremor of one hand and advances to slow movement and stiffness. The face might show little no symptoms in the beginning but the speech might become slurred. With every passing day, the condition worsens. This condition has no permanent cure but the symptoms can be improved with proper medication.

What are the symptoms?
Some unmistakable symptoms include the following:

A sudden shaking of the limb. A sudden tremor of the hand is a very common symptom of this disease.
A stiffness of the muscles that can limit the range of motion and sharp pain.
The posture of the body might get compromised. Often balancing problems are witnessed among many patients.
There could be problems with speech leading to soft, slurry or quick speech. The speech in some cases can become monotonous devoid of inflexions.
Parkinson s disease can lead to slow movement and makes performing of simple tasks difficult.
Patients often find writing very difficult
What are the possible causes of Parkinson s disease?

Specific genetic mutation can lead to Parkinson s disease in folks who have a family history of Parkinson s disease. Certain variations of the gene increase the risk of this disease
Exposure to certain environmental factors or certain toxins can trigger Parkinson s disease in an individual.
Certain cells in the brain known as Lewy bodies can trigger Parkinson s disease.
A certain kind of protein cells within the brain known as alpha-synuclein can trigger the Parkinson s disease in an individual
What are the risk factors?

Heredity: Having an immediate family member or a close relative suffering from Parkinson s disease can increase the risk of getting this disease in an individual
Age: Although not a prime risk factor, but an individual over the age of over 60 have an increased risk of getting this disease
Toxins: Exposure to pesticide or certain herbicide increase the risk of Parkinson s
Sex: Men are more likely to get Parkinson s disease than women
What is the medication for Parkinson s disease?

Carbidopa-levodopa: This is a natural chemical that gets passed to the brain and is converted to dopamine by the body. The benefits of this medication might reduce with increased symptoms.
Carbidopa-levodopa infusion: A popular drug in this category is known as the Duopa. It is administered directly into the small intestine in the form of gel through a feeding tube.
MAO-B inhibitors: Drugs from this group include rasagiline and selegiline. This is a powerful medicine. Many patient experiences hallucination during the initial days of consuming these drugs.
Anticholinergics: This medication is mainly used to counter tremors of the limbs in the early stage of the Parkinson s disease.

Parkinson's Disease - What Are The Risk Factors?

Sleep apnoea is a kind of disease that can affect people of any age and is basically a kind of sleep disorder. The person suffering from sleep apnoea may feel extremely tired and fatigued even after having a full night s sleep and his snoring may become extremely loud which is again a serious problem.

What are the symptoms of sleep apnoea?

There can be many cases where the symptoms of central sleep apnoea and complex sleep apnoea may be overlapping which makes it a bit difficult to get diagnosed properly. But, there are certain very basic symptoms of sleep apnoea.
Very loud snoring is a basic characteristic of patients with sleep apnoea.
The patient may suffer from regular episodes of cessation when they are sleeping as might be pointed out by other people.
The patient may awaken from sleep regularly due to shortness of breath and problems in the sleeping order.
The patient suffering from sleep apnoea may wake up from sleep with a very dry mouth and or a sore throat.
The patient may suffer from a bad headache often and in many unfortunate cases, the patients may also suffer from insomnia which is the problem of sleeplessness.
Patients of sleep apnoea suffer from intense problems of irritability and bouts of morning sleepiness.
Shortness of breath may intensify in a patient so much so that the person may get awakened from sleep gasping for air as if choking.
Excessive bouts of daytime sleeping may cause a person to perform very poorly in his work as well.
It is at these times when a patient should immediately consult a doctor for a proper treatment and further solution to this problem.

Causes of sleep apnea

Obstructive sleep apnoea is caused when the muscle in our throat starts relaxing. It is this muscle that gives support to the triangular piece of tissue that hangs from the uvula which is the soft palate and the side walls of the tongue. Basically, when this muscle relaxes, the airways in the body gets narrowed as a result of which the blood does not get enough oxygen which is required for proper breathing. It is then that the brain starts sending signals to get up from sleep so that the nasal passage can be reopened for sufficient amount of oxygen.
There can also be cases where the brain is unable to send a proper signal to the muscles that help us to breath as a result of which a person does not breathe for a certain period of time. This, in turn, makes the patient awaken abruptly from sleep with shortness of breath and the patient finds it difficult to fall asleep.


Sleep Apnea - Know The Common Signs Of It!

Obesity is the new-age lifestyle disease with multiple ramifications. While its effects on the physical aspects are very evident, the damage it does to the brain are more severe, though not obvious. Read on to know some harmful effects of obesity on the emotional well-being.

Leads to binge eating: There is a certain pleasure in eating sugary and fatty food, and this is lost with depression. Therefore, to get that emotional satisfaction, people tend to eat more chocolates, cookies, milkshakes, and other weight-accumulating food items, which further add to obesity. Greater the weight gained by a person, lesser the response or happiness from such food products.
Increases impulsivity: The area of the brain known as orbitofrontal cortex, which is in charge of controlling impulsivity, shrinks in obese people. This results in people eating more impulsively.
Affects immunity: Obesity is a major cause of inflammation, leading to damage in certain parts of the brain. This impairs the immune system, making the affected person more prone to infections and tissue damage. This leads to increased chances of diabetes, heart disease, stroke, sleeping disorders, eating disorders, etc. The chemical known as C-reactive protein increases as seen on MRIs in obese people, and which is usually seen in patients with chronically increased inflammation.
Effects on memory: As the BMI increases, there is a decrease in scores of memory tests. This effect is more obvious in women after menopause. With increased fat accumulation, more hormones are released, which affects the memory. Increased inflammation also affects cognition and memory.
Increased risk of dementia: With more belly fat accumulating, there is extra stress on the body to burn the visceral fat. This reduces brain size and causes certain hormones to release, which further affects the body s ability to remember things. It has been proven that people with smaller brain size are at greater risk for developing dementia.
Weight loss stress adding to more stress: When obesity sets in and the BMI goes up, there is an added pressure to lose weight, which further ups the stress levels. During these dieting days, the brain is constantly alert and finds ways to eat more. This also leads to excess eating. Moreover, there are indications that there could be genetic changes during this phase, which may leave a permanent mark in the person s composition.
Depression: When a person is not happy with their reflection in the mirror, the chances of feeling good and happy are very less. In this age, where aesthetics plays a major morale booster, an obese image staring back does not help at all.
So, if you have a risk of obesity, watch out. It is not just how you look, but how you feel is also altered.

Obesity - How It Affects The Human Brain?

Epilepsy is a neurological condition that leads to recurrent seizures. Seizures arise when electrical activity in the brain suddenly surges causing a temporary disturbance within the messaging systems located between the brain cells.

Epilepsy is more common in children below the age of two years and adults above the age of 65 years.

Seizure Types

Seizures are classified into two main categories depending on their area of impact. 

A focal seizure is one that affects only one part or area of the brain whereas a generalised seizure affects the whole brain. Further, both focal and generalised seizures have various sub-categories which are as follows-

Previous nomenclature- 

Partial Seizure

  Simple Partial Seizure
  Complex Partial Seizure
  Partial Seizure with Secondary Generalization

Generalized Seizure

  Absence Seizures
  Myoclonic Seizure
  Atonic Seizure
  Tonic Seizure
  Tonic-clonic Seizure
  Mixed Seizure
  Status Epilepticus

Latest nomenclature of seizure types:

Focal seizures-

  Focal aware seizures
  Focal impaired awareness seizures (previously called complex partial seizures)
. Bilateral tonic clonic seizures

Generalised onset seizures-

  Tonic clonic seizures.
  Atonic seizures (sometimes called drop attacks) and tonic seizure.
  Myoclonic seizures.
  Absence seizures.

Symptoms

The well know symptom of epilepsy is a convulsion/ fit, a few other symptoms include-

  Intermittent spells of fainting. When this happens the patient is likely to lose control of his/her bladder or bowel movements. Following this, the person is likely to suffer from extreme tiredness.
  Spells of a blackout with difficulty in remembering
  Becoming unresponsive to any instructions or questions asked during brief periods of time
  Bouts of continuous blinking without any known reason
  Inappropriate movements that keep on occurring
  Changes in sensory perceptions
  Sudden stiffness in the body

Reasons for Epilepsy

Messaging systems within the brain are responsible for every function that goes about in your body. A disruption to this system caused by defective electrical activity leads to epilepsy in a person. Many people inherit epilepsy while others may develop this condition as a result of-

  Head trauma sustained during an accident
  A stroke or a tumour that has affected the brain impairing its normal capabilities
  An injury to the brain before or during birth
  Associated with developmental issues
  Infections of the brain

Treatment for Epilepsy

Epilepsy in childhood can be treated by using medications and by adopting dietary changes in some cases. Medications for epilepsy mainly include-

  Anticonvulsants - Helps control seizures and manages the symptoms of epilepsy
  Medications for nerve pain - Reduce pain that is caused by the damaged nerves

These medications should be consumed as and when prescribed by the doctor. You must consult a paediatrician for this, as he/she will take your child s physical and mental in consideration before starting the treatment.

Seizures that occur in childhood may be benign. This means that it will not continue into one s adult life. Further, those children who have suffered from epilepsy in their childhood have been seen to have normal mental and intellectual development in their adulthood. However, some epilepsy syndromes in children can have a devastating effect on the child.

Seizure threshold is a term that is used to refer to the conditions that are important for the production of seizures. The threshold is lower for people who are more prone to having seizures whereas the threshold is higher for those who do not have a tendency to suffer from seizures.
