Strokes occur when blood to the brain gets interrupted or reduced. When this occurs, brain cells begin to die as they don't get enough nutrients and oxygen. Such life-threatening episodes can strike you anytime.


Many myths surround this medical condition:


Myth 1: Women don't suffer from strokes
The opposite is true. It is women who suffer strokes more often than men. This is because women tend to live longer than men whose longevity gets affected by heart disease. Since they live longer than men, they tend to be more vulnerable to strokes.


Myth 2: Strokes aren't easy to recognise
Strokes can be easily diagnosed through the face, arm, Speech and Time test (FAST). If you suffer from slurred speech, facial droop or numbness on one side of the body, you're said to suffer from a stroke.


Myth 3: Strokes are a form of heart attack
Although strokes and heart attacks are closely related, they are not the same. In strokes, blood supply to the brain gets interrupted; on the other hand, in heart attacks, blood supply to the heart gets severely affected.


Myth 4: Only older people suffer from strokes
This isn't true young people can experience strokes as well. About a quarter of stroke cases are reported by people aged 65 and below. More importantly, irrespective of the age group, the warning signs are the same; it is only in response that differences can be found between younger and older people.


Myth 5: Strokes can't be prevented
Through changes in your lifestyle, strokes can easily be prevented. You can reduce your chances of getting a stroke by having a balanced diet, exercising, keeping an optimum body weight and limiting alcohol consumption as well as quitting smoking. Moreover, up to 80% stroke cases can be prevented by leading a healthy lifestyle.


Stroke - Debunking Myths About it 

A stroke may be called a brain attack. It may happen to any person at any time. A stroke occurs when blood supply to the brain is cut off. The brain cells become oxygen deprived due to the stroke and eventually die. Dead brain cells result in brain dysfunction due to which patients lose control over muscle and memory.

Strokes can be mild to life threatening and requires immediate medical attention. Stroke requires advanced care and should be treated by extensively qualified and experienced medical experts. 

Neurosurgery satisfies all the required clauses for treatment of stroke and accounts for being one of the best ways for management of stroke. Renowned hospitals have a dedicated neurosurgical wing and a team of neurological specialists who know how to deal with stroke the best.

Vascular Neurology
This form of neurology focuses on patients who have undergone a stroke or have experienced symptoms of stroke. A multidisciplinary approach is taken for the prevention of recurrent cerebrovascular conditions.

Types of stroke

Ischemic stroke: This kind of stroke occurs when there is a blockage in a blood vessel, which supplies blood to the brain. This form of stroke is the more common. The underlying cause of this stroke is known as atherosclerosis, which is a condition where fatty deposits occur in the walls of the blood vessels and cause blockage in them.
Hemorrhagic stroke: This type of stroke occurs when a blood vessel gets weak and ruptures into the brain. This is caused by two types of weak blood vessels known as aneurysm and arteriovenous malformation.
Transient ischemic attack: This type of stroke is also known as a mini stroke. These attacks occur because of blood clots. The blockage caused is temporary or transient in nature.
Treatment of Ischemic stroke

Tissue Plasminogen Activator: This is one of the best ways to treat ischemic strokes. This medicine is given to the patient intravenously. It dissolves the blood clot and improves blood flow to the area of the brain which is affected. The medicine should be given within three to four hours after stroke symptoms appear.
Endovascular procedure: This is a process by which the blood clot is removed using a catheter, which gets inserted into the area of the blocked blood vessel. It helps in restoring blood flow to that area. 
Treatment of Hemorrhagic stroke

Endovascular procedure: Several endovascular techniques and methods are used so that the weakening of blood vessels is reduced and less bleeding is caused.
Surgical treatment: Different modes of neurosurgery may be undertaken to stop bleeding and for relieving pressure within the skull.

Role of Neurosurgery in Management of Stroke

Automatic Implantable Cardioverter Defibrillator is an electronic device that is located in the chest of the patient suffering from arrhythmia. Arrhythmia is a condition which causes abnormal rhythm of heartbeat in the patients. It is a life-threatening condition. The device is located in the chest to correct the rhythm of a heartbeat.

AICD device works in two ways:

Firstly, it tries to correct the abnormal heartbeat rhythm and release high- speed heartbeat pace. This is called cardioversion. Patients with AICD generally do not feel the process.

However, if the effect of cardioversion is null then the device will give a mild electric shock to the patient's heart to correct arrhythmia and reset the rhythm.

This second method is called defibrillation. The patient can feel the defibrillation.

The modern-day AICD device is programmed to store the data about the patient s heart rhythm. Doctors use the programmed device which contains your condition and provides medically correct therapy.

Preparation for AICD Implantation

The patient is required to fast six hours before undergoing the surgery. On admission, prescribed medicine is given to the patient and the latest heart condition is measured by an ECG test. If the patient is on blood-thinning medication, then it will be stopped 24 hours before the surgery.

The procedure will be carried out by a cardiologist. The patient will remain under observation in the hospital for at least two days.

Procedure

The entire process of setting up the device in the chest of the patient takes about 2 hours. The patient is sedated, and the area below the collarbone is numbed for the operation. A small incision is made in the chest area. With the help of imaging techniques, cardiologist sets up the device in the chest. The device is then connected to the veins and the heart. After the surgery, the patient is kept under observation. Heart rate, blood pressure, and overall health condition are observed by the doctors to determine successful implantation of Automatic Implantable Cardioverter Defibrillator (AICD). Post Procedure After the successful recovery of the patient, doctors usually discharge the patient with AICD attached. The doctors give complete care instructions of the device along with health. Doctors also guide the patient through the list of activities that one can and cannot perform. AICD is a life-saving device. Hence, proper care and regular check-ups are recommended by the doctors. The regular check-up of the device is also essential since the device runs on a battery. The doctors also train the patient about the workings of the device. They will also explain about the mild shocks of the device one may receive to correct the arrhythmia. Before leaving, make sure the site of the surgery is dry and healing, and you do not have a fever for the past 24 hours.

What Happens When the Electrical Activity of Your Heart Changes?

The heart's electrical conduction system plays a very important role in cardiovascular functioning. Also known as the atrioventricular (AV) conduction system, it regulates and controls the timing of the heartbeat.

How does the heart's electrical conduction system work?

There is a collection of electrical cells in the upper right atrium of the heart known as the sinoatrial (SA) node which acts as a natural pacemaker and generates electrical signals. These signals travel through specialized electrical pathways and stimulate the muscular walls of the heart to contract in a rhythmic manner. This gives rise to the heartbeat that pulses at a specific frequency every minute.

What is the effect of fluctuations in electrical activity on the heart?

The standard heart rate in human being ranges from 60 to 100 beats per minute. It slows down when a person sleeps and speeds up when one experiences physical or emotional heightening. These fluctuations are triggered by the brain or other systems of the body and signal the SA node to generate charges more rapidly or slowly. This leads to spikes and drops in the heart rate, depending on the nature of the situation.

What happens when there is dysfunction in the heart's electrical activity?

When the heart's electrical conduction system does not function properly, it leads to the occurrence of a condition known as arrhythmia or abnormal heart rhythm. This happens when electrical impulses are generated in an irregular manner and causes tachycardia (rapid heartbeats) or bradycardia (slow heartbeats) which takes place in jarring infrequent tempos.

What causes fluctuations in the heart's electrical activity?

There are various kinds of triggers that cause the heart rate to fluctuate. The exact nature of fluctuation also depends on the type of trigger. A few everyday examples of these causes are as follows:
- Exercise and strenuous physical activity increases electrical activity as the heart is required to beat faster so as to increase the supply of blood and oxygen to the muscles.
- Sleep and rest reduce heart rate as the body is not needed to exert itself.
- Release of adrenaline into the bloodstream causes the heart rate to spike up.

 Heart Care In Your Hands: World Heart Day Special Tips

Cystic fibrosis is a genetic condition, which primarily affects the lungs and persistence of this condition might lead to severe breathing problems and loss of lung function. If you have inherited two copies of the defective gene from your parents, you are likely to suffer from this disease. Cystic Fibrosis causes a buildup of thick mucus in your lungs and affects other organs such as the kidneys, pancreas and the intestines in your body.

It isn't very uncommon as one out of fifty people in Asia is a carrier of this disease. The disease gets its name from the cysts formed in the pancreas of the sufferer. However, this disease can be detected by testing the quantity of salt present in your sweat. Prenatal testing for Fibrosis is another method to test if your newborn is likely to contract a lung infection.

Complications faced due to cystic fibrosis include:
1. Serious sinus infections
2. Serious damage in lungs due to inflammation and incessant infection
3. Malnutrition
4. Complication in breaking down protein
5. Respiratory tract contamination

If you observe one or more of the following symptoms, you might be suffering from Cystic Fibrosis:
1. Salty-tasting skin
2. Bowel obstruction caused due to meconium ileus (obstruction of the bowels)
3. Mucus amiss in your alveoli
4. Persistent coughing with phlegm discharge
5. Shortness of breath while engaging in a physical task
6. Stunted or measly growth despite healthy lifestyle habits
7. Infertility in males

If you're suffering from cystic fibrosis, there isn't any particular treatment which is recommended due to the varying degrees of it found in people. However, consultation with a medical practitioner and an individualised treatment plan can help you minimise the risks and lead a better life.

Some therapies you can opt for are:
a) Airway clearance: This therapy helps sift the thick layer of mucus around your organs. Some people have also chosen to use the inflatable vest which vibrates around your chest, thereby, thinning and loosening the layer of mucus.

b) Inhaled medicines: Another breakthrough in the field of respiratory medicine, this method requires the patient to sniff a liquid consisting of mist, which is inhaled with the aid of a nebuliser. This method is known to be beneficial for opening airways.

c) Pancreatic enzyme supplements: Along with multivitamins, these specially designed supplements are known to cater to your pancreas with the much-needed nutrients and they need to be consumed with every meal.
