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!

We're all guilty of making fun of snorers, but sometimes this snoring can be a symptom of sleep apnea. Sleep apnea is a condition where breathing is not continuous and may start and stop many times while asleep. This affects the quality of your sleep and in turn can affect many aspects of your health including your cardiovascular health. Here's how:

High blood pressure
When a sleep apnea patient's breathing stops, the oxygen levels in the blood also suddenly fall. This can increase your blood pressure. High blood pressure means that the heart muscles need to work harder to pump blood through the body.

Cardiomyopathy
As a result of high blood pressure, the heart walls may become thicker and the heart muscles become stiffer. This is known as cardiomyopathy. As this condition worsens, the heart becomes weaker and is unable to maintain a regular rhythm. This can eventually lead to heart failure.

Arrhythmia
An irregular heartbeat is also known as arrhythmia. This may also be related to the changes in the heart's structure that follow the drop in blood oxygen levels. In many cases, arrhythmia has no visible symptoms and can often go undiagnosed. This can result in the formation of blood clots in the atria which can lead to a stroke.

Sleep apnea is easy to diagnose. If the doctor feels that you show symptoms of sleep apnea, you may be asked to stay on the hospital overnight and undergo a sleep evaluation. This tests a variety of body functions including brain activity, eye movements, heart rate, breathing patterns and blood oxygen levels.

Treatment for sleep apnea depends on the causes for this condition. If you are overweight, regular exercise and a change in diet can help you lose the excess weight and cure sleep apnea. Similarly, if your sleep apnea is triggered by an allergy, treating the allergy can help cure the sleep apnea. Other forms of treatment for sleep apnea may include:

Continuous positive airway pressure (cpap)
This is a machine which pumps air into the body through a nasal mask. By keeping the pressure in the machine higher than normal air pressure the upper airway passages are kept open and hence the quality of your sleep is improved. An auto cpap machine can modulate the air pressure such that it is higher when you inhale and lower when you exhale.;

Oral devices
Your doctor may suggest oral devices that allow you to keep your mouth open while you sleep. This is easier to use than cpap machine but less effective. Surgery is the last resort when it comes to treatment for sleep apnea.

Sleep Apnea and Its Link to Heart Failure

Antibiotics are something which have changed are lives for eternity as well as for the better, to say the very least. With each day that passes, there are greater strides of advancement which are made in the field. Of late, it is said that antibiotics also have the potential to stop new cells in the brain from growing, which is quite a risk when it comes to their usage among people are sick.

Research has found that if the brain of the person under treatment is subject to sustained use of antibiotics, it is true that the brain can lose its functionality for a quicker time than what one would consider to be normal. So it can be said, this usually is not the advisable way to go.

Like most testing practices when it comes to medication, antibiotics which were tested on the brains of the subjects i.e. those of mice had an effect of mitigating their high-level memory. How this happened to be is rather interesting, to say the very least.

How dangerous can antibiotics be?
It is often said that eating right does wonder for a person s brain. Well, the mice that were not treated with the antibiotics were seen to lose the healthy bacteria present in their stomachs. In addition to this, they lost new brain cells. This led on to them performing worse in mental tests than their peers who had had some antibiotics administered to them on a consistent basis.

Now a cynic may point out that what is seen to be true for mice may really not hold true when it comes to humans being considered. However, if it is taken into due account that a lot of path-breaking research is carried out on mice, there is quite some credence to the results of the study.

To supplement the evidence even further, it was also seen that for mice which were in possession of low levels of monocytes, which are a type of white blood cells. It was seen that there was a great dependency on monocytes for the generation of white blood cells. The part of the brain which is hindered by generating new cells on account of the sustained use of antibiotics is the hippocampus.

Antibiotics are the proverbial shot in the arm which can aid recovery by destroying the threat to a person s wellness. However, it is to be considered that they are not safe in general as there is collateral damage!

Migraine vs. Headache: know the difference

How to differentiate between a migraine and headache?

When you feel pain or pressure in your head, it may become difficult for you to assess whether you are experiencing a common headache or a migraine. Let's understand how different they are from each other.

A typical headache usually affects both sides of your head and varies from a mild to moderate pain. It can last from 30 minutes to up to a period of one week.

Some specific areas which get affected by a headache are:

  temples

  forehead

  back of your neck

Factors that trigger this headache type are a muscle strain, stress or anxiety. 

A migraine, on the other hand, is also a type of a headache which results in an acute throbbing sensation in one part of your head. Usually, migraine headaches are highly painful. Migraine pain makes it difficult for a person to carry out his/her daily tasks. Symptoms or signs associated with migraine attacks are:

  vomiting

  nausea 

  sensitivity to sound or light

  pain in the temples

  temporary loss of vision

  pain behind your ear or eye

What are the common causes of a migraine?

  hormonal imbalances in women - fluctuations in oestrogen, especially during menopause or pregnancy seem to trigger a migraine

  drinks like wine and extremely caffeinated beverages 

  foods such as salty foods, aged cheese as well as processed foods can trigger the migraine attack.

  medications - vasodilators such as nitroglycerine and oral contraceptives can intensify migraine pain.

How to treat a headache?

Fortunately, you can get rid of stress-induced headaches through over-the-counter treatments, which include:

  aspirin

  acetaminophen

  ibuprofen

How to treat a migraine?

If you experience migraine attacks less frequently, these medicines may give you quick relief:

  triptans, such as rizatriptan (Maxalt) or almotriptan (Axert)

  antinausea medicines, such as chlorpromazine (Thorazine), promethazine (Phenergan) or prochlorperazine (Compazine)

  non-steroidal anti-inflammatory drugs (NSAIDs), such as acetaminophen, naproxen sodium, aspirin or ibuprofen

Some preventive tips:

  make changes in your diet such as avoid such foods, including caffeine and alcohol which are believed to trigger headaches.

  you can also try muscle relaxation exercises, yoga or meditation to ease the migraine attack.

Migraine Vs. Headache: Know the Difference

With age, just like other body functions, the mind too begins to slow down. This could lead to problems in communication, focus, recall, reasoning, and thinking. So with dementia, the person faces problems which are a combination of above-mentioned activities. Dementia is a symptom associated with many diseases and is not a disease on its own.

Alzheimer s is the main cause of dementia, followed by stroke or brain injury, Huntington s disease, and Lewy body disease. However, there are some symptoms that can be indicative that a person is gradually progressing into dementia. Watching out for these symptoms can help one seek help at an early stage, thereby helping the affected person, and slowing down its progress.

Short term memory loss: With age, people tend to forget what happened recently, and this can even be something as recent as the previous day. However, they can very clearly recollect events from the past. They might forget things like where they have placed their glasses, where the television remote control is, etc. They may also ask for the same information repeatedly, even after it is answered.
Mood changes: Rapid mood swings is observed in a person suffering from dementia. Their emotions keep changing within a matter of seconds, and they may show also less emotion than what they used to show previously.
Personality changes: Since dementia affects reasoning and judgment, someone who was earlier shy could suddenly become outgoing. Their inhibitions which led to a shy personality are lost, making them more outgoing.
Difficulty in performing regular tasks: Be it forgetting things like laying out tables, keeping things back in their places, or organising medical kits, with dementia setting in, these tasks slowly become more difficult to do. Also, learning new tasks, even simple ones, seem tough and are often not accomplished.
Losing storylines: The elderly would usually be good with telling and appreciating stories like telling tales to their grandchildren or following television soaps and stories. However, as dementia begins to set in, they tend to lose storylines, both when observing and telling.
Repeating actions: As they are not able to register things, they tend to repeat things, both in words and in actions.
Feeling lost: Things like heading out to a store to buy something and then wondering why they came there are common. Short-term memory loss can cause such situations. This confusion, especially with regard to time and things, is very common.
Spatial and time orientation: There could be problems relating to space and time, seasons, and they may often ask questions like what time it is, etc. Routine tasks like paying bills, cooking using recipe books, which were easily managed, suddenly begin to look difficult.
Apathy: Losing interest in people, hobbies, or other things like puzzles, which they once enjoyed, become boring and unenjoyable.

9 Early Symptoms of Dementia!

With age, most body organs begin to deteriorate in their function. This happens to the brain also, thereby reducing the overall speed of functioning of most organs. While slowing of bodily movement is visible, the internal organs functioning also slows down, which is not that obvious. Memory loss or dementia is one of the main manifestations of this degeneration of the brain.

Alzheimer s is the most common form of dementia, and the associated symptoms includes reduced reasoning abilities and cognitive defects. Though it is seen only in the elderly, not all elderly people will have Alzheimer s. The overall quality of life of the affected person is reduced with difficulty remembering things that were recently learned. It is a progressive disease and as it gets more severe, a full-time caretaker may be required.

Causes: The brain cells are affected by protein masses known as plaques and tangles. These hamper the way communication between the brain cells happens as well as affect nutrition from reaching all parts of the brain. This leads to shrinking of the brain, eventually leading to memory loss and other problems. There is also a strong genetic linkage, as most people with Alzheimer s have the lipoprotein A gene.

Symptoms: Though memory loss is the most common symptom, there are other symptoms:

Being confused about places, people, and times
Inability to find the right words during conversations
Regular objects are misplaced
Becoming irritable, (in someone who was not so previously)
Mood swings
Personality changes
Inability to organise thoughts
Not able to make the right decisions
Repetitive talks and actions
Forgetfulness (not something the person always does)
Difficulty with numbers (again, not something calculations
Difficulty managing everyday tasks and minor problems
Suspicion of others (like immediate family members and friends)
Risk factors: While age is definitely a risk factor, the fact that not all aged people develop Alzheimer s is to be borne in mind. Other risk factors include the history of stroke, high cholesterol, high blood pressure, diabetes, smoking, obesity, and poor lifestyle choices.

Diagnosis: While there is no definitive way to diagnose Alzheimer s, symptoms along with brain scans and neuropsychological function testing are useful ways to confirm the diagnosis.

Treatment: This is aimed at two things reducing the rate of disease progression and treat (or reverse) symptoms if possible.

Cholinesterase inhibitors improve cellular communication in the brain and also manage depression and agitation. Memantine is used to slow the pace of disease progression.
In people with the disease, small changes are useful to help them with the symptoms. These include keeping essential things like keys and wallet in the same place, keep a daily diary to help them remember things, keep pictures of friends and family within visible distance.
