A brain stroke can affect anyone at any point of time when the supply of blood to the brain is interrupted. It can threaten major physical functions and can prove to be fatally dangerous at times. The brain stem which is placed right above the spinal cord controls the breathing, heartbeat and levels of blood pressure. It is also in charge of controlling some elementary functions such as swallowing, hearing, speech and eye movements. 

What are the different types of strokes?
There are three main kinds of stroke: ischemic strokes, hemorrhagic strokes and transient ischemic attacks. The most common type of brain stroke is the ischemic stroke is caused by narrowing or blocking of arteries to the brain, which prevents the proper supply of blood to the brain. Sometimes it so happens that the blood clot that has formed elsewhere in the body have travelled via the blood vessels and has been trapped in the blood vessel which provides blood to the brain. When the supply of blood to a part of the brain is hindered, the tissue in that area dies off owing to lack of oxygen. The other variant of brain stroke is termed as hemorrhagic stroke is caused when the blood vessels in and around the brain burst or leak. Strokes need to be diagnosed and treated as quickly as possible in order to minimize brain damage.  Remembering the F.A.S.T. acronym can help with recognizing the onset of stroke (Face, Arms, Speed, Time - explained below). 

What are the common symptoms of a brain stroke?
The symptoms of the brain stroke are largely dependent on the area of the brain that has been affected. It can interfere with normal functioning, such as breathing and talking and other functions which human beings can perform without thinking such as eye movements or swallowing. Since all the signals from the brain as well as other parts of the body traverse through the brain stem, the interruption of blood flow often leads to numbness or paralysis in different parts of the body.

Who is likely to have a stroke?
Anyone is at a risk of developing brain stroke although ageing is directly proportional to the risk of having a stroke. Not only that an individual with a family history of brain stroke or transient ischemic attack is at a higher risk of developing stroke. People who have aged over 65 accounts for about 33 percent of all brain strokes. It is important to point here that individuals with high blood pressure, high blood sugar, cholesterol, cancer, autoimmune diseases and some blood disorders are at a higher risk of developing brain stroke.

There are a few factors which can increase the risk of developing stroke beyond any control. But there are certain lifestyle choices as well which aids in controlling the chances of being affected by stroke. It is crucial to refrain from long-term hormone replacement therapies as well as birth control pills, smoking, lack of physical activity, excessive use of alcohol and drug addiction. A brain stroke is a life-threatening medical condition, and when an individual has symptoms that resemble that of stroke, it is crucial to seek immediate medical help.

Treatment for stroke

Treatment depends on the type of stroke.
Ischemic strokes can be treated with 'clot-busting' drugs.
Hemorrhagic strokes can be treated with surgery to repair or block blood vessel weaknesses.
The most effective way to prevent strokes is through maintaining a healthy lifestyle.
What is TPA?
TPA is a thrombolytic or a  Clot Buster  drug. This clot buster is used to break-up the clot that is causing a blockage or disruption in the flow of blood to the brain and helps restore the blood flow to the area of the brain. It is given by intravenous (IV). This can be given only within 4.5 hrs of the onset of symptoms

Time is brain

Remember Every second Loss means brain cells die.
Rush to the nearest Stroke Centre whenever you experience such symptoms.
U can save the brain cells dying if you reach within 4.5 hrs by the CLOT BUSTER. 
Endovascular procedures 
Another treatment option is an endovascular procedure* called mechanical thrombectomy, strongly recommended, in which trained doctors try  removing a large blood clot by sending a wired-caged device called a stent retriever, to the site of the blocked blood vessel in the brain

Stroke prevention
The good news is that 80 percent of all strokes are preventable. It starts with managing key risk factors, including 

High blood pressure,
Cigarette smoking,
Diabetes
Atrial fibrillation and
Physical inactivity.
More than half of all strokes are caused by uncontrolled hypertension or high blood pressure, making it the most important risk factor to control. 
Rehabilitation
The best way to get better after a stroke is to start stroke rehabilitation ("rehab"). In stroke rehab, a team of health professionals works with you to regain skills you lost as the result of a stroke.

Brain Stroke - Things You Must Know!

Stroke is one of the major reasons for disability in adults. In the US alone, 7 million people suffer from a stroke in a year. After a stroke, the affected individual suffers from lots of health issues. They feel week and fatigued. An ache in one side of the body, inability to walk, and social disability are experienced. Emotional and cognitive functioning is disturbed. Continuum care is recommended for the affected individuals and they need interdisciplinary care to ensure they can do things independently. This is where occupational therapy plays a vital role.

What does the therapist do? 

Using a range of evidence-based methods, the occupational therapists can address the physical, emotional, and mental challenges caused by the stroke. Occupational therapy does not concentrate only on the ailment. It takes into account the emotional needs, desires, limitations, and activities of the stroke survivors. It helps them to recoup the skill to get the daily chores done independently. An occupational therapist surveys the home of the stroke survivor and evaluates the risk of hazards. The practitioner also helps the affected individuals in coping with the loss of vision and memory. The physical strength and fortitude are augmented. The major focus will be on making the affected reach the heights of performance in the valued occupations.

How does it help? 

Studies prove that occupational therapy does not only help one to recover faster, but also prevents worsening of the condition further. The stroke survivor, who receives the occupational therapy, is independent when it comes to daily living chores. Wouldn t it be a great improvement on the emotional health when the affected feels he or she can get things done with little or occasional help? Also, this reduces the caregiver burden. The family is relieved that the survivor can eat, bath, and take a few things without someone having to sit closer and help. This mentally boosts the caregivers and the family to motivate the survivor. The stroke survivor also looks forward to the rehabilitation treatment as the occupational therapy makes them feel great.

Transitional and community integration services can make sure that the patients are engaged in their specific environments, once they get back home after occupational therapy in the specialized care center. After a certain period, when the stroke survivors show considerable improvement, the practitioner again evaluates to find if activities like driving can be resumed by the clients. Community mobility of different choices is recommended if the client is not fit for driving. There are driver rehab programs and the driving skills can be regained.

An occupational therapist spends more time with the client than any other healthcare professional. This is because the practitioner is responsible for alleviating the challenges faced by the affected individual emotionally and physically. The practitioner not only helps the client to achieve the goals but also ensures that the client is psychologically motivated whenever he or she is discouraged. Rehabilitation can reverse the damage done to the brain. But it takes lots of efforts to learn the things to do them in a different way. An occupational therapist makes this goal easier for his or her clients.

Occupational Therapy For People Recovering From A Stroke! 

How many of us have heard about Extracorporeal Membrane Oxygenation (ECMO) before Tamil Nadu, Chief Minister late J Jayalalithaa was put on it for recovery? Hardly a handful. Patients who are placed on the device have 50-50 chance of survival and while it could not help the late Chief Minister, her condition put a spotlight on ECMO.

What is ECMO?
ECMO is a life support device that is put in place when a patient's heart and lungs stop functioning completely post a cardiac arrest. When the patient does not respond to Cardio Pulmonary Resuscitation (CPR), the patient is put on ECMO.

Function of ECMO
The core function of the device is to separate carbon dioxide from the blood and add oxygen into it. It takes the load off from heart and lungs, providing critical time to the body organs for its treatment and recovery.
Patients are only put on ECMO, if there is a chance that the condition can be reversed.

How does ECMO work?
The device drains blood from a vein, which is attached to an oxygenator machine. The machine then removes carbon dioxide from the blood and adds oxygen to it. Depending upon the condition of the patient, the warm blood is either pumped into the body with the help of the machine or is transferred back into the body through an artery.

How long a patient can be on ECMO?
After seven days of being put on ECMO,there are chances of patient getting an infection.
In case the patient contracts an infection, it is recommended to take the patient off ECMO support.

6 Things that make you prone to heart diseases the most

Every year almost 2 lakh people opt for heart surgeries in India; and as of 2015 there were about 30 million people in the country suffered from heart diseases. There are several factors that increase the threat of heart diseases, among which some can be controlled and some can't. On one hand, where factors like being a man, old age, being a woman in the post-menopausal phase of life, and a family history of heart diseases are beyond your control; other risks can be minimized by making some lifestyle changes. 

Although natural processes like ageing, which narrow down your arteries and weaken the heart muscles increase the risk of heart diseases here are 7 factors, which dramatically increase your chances of getting heart diseases, while you are still young.

1. Genetic Factors: 
If someone in your family is already suffering or has suffered from a heart disease, especially at a young age, it increases your probability of getting a cardiovascular disease.

2. High Levels of Cholesterol in the Blood:
Chances of formation of plaque on the inner walls of the arteries increase with increasing levels of bad (LDL) cholesterol in the blood. This may be a major cause of the heart disease, atherosclerosis, which happens due to accumulation of fatty substances inside the arteries. 

3. Smoking:
Smoking causes constriction of your blood vessels and may damage their inner lining due to the effect of nicotine on them. This can put you at high risk of developing atherosclerosis. Moreover, studies suggest that people who smoke are twice as prone to heart attacks in comparison to non-smokers.

4. Hypertension:
If your blood pressure level is usually above normal, it can give rise to thickened arteries, which, in turn, can reduce the passage for the flow of blood through the vessels. This damages your heart health to a large extent and makes you prone to heart diseases.

5. Diabetes:
Uncontrolled diabetes increases your chances of getting a heart attack, especially because diabetes almost goes hand in hand with diabetes and obesity, which are risk factors of heart diseases.

6. Stress:
If you fail to keep your levels of stress and anger in check, they may have a damaging effect on your arteries. This can make way for strokes and heart attacks in the future.



The 6 Things that Make You Prone to Heart Diseases the Most

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.

How Do You Recognise a Stroke?

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.

There are certain signs that can help you to clearly recognise an occurrence of stroke:

Face drooping on one side
Weakness or numbness on one side of the body, usually a leg or an arm
You're unable to think or say anything clearly
You experience slurred speech
Difficulty in moving your tongue
You get a sudden and severe headache

What Tests can be Done to Identify the Stroke?

There are certain tests that you can do to identify these warning signs.

To identify facial weakness, the smile test is used wherein you're simply asked to show your teeth to check for any changes in this facial expression - a lopsided smile.

To check for weakness in the body, the arm test is performed in which you raise both your arms to the same height. In case you're unable to do so, you may be experiencing arm weakness, a sign of stroke.

For slurring of speech, you may be asked to repeat sentences such as 'Don't cry over spilt milk' or 'The pen is mightier than the sword'.

Stroke can also be identified through the walk test wherein with the help of another person, you walk across the room to check for changes in your step.

If not treated in time, strokes can cause permanent brain damage. More importantly, unlike heart attacks, anxiety may not always be the cause of your stroke symptoms. That's why, being aware of these symptoms and recognising them on time can help you to quickly seek medical assistance.
