Headaches are one of the most common types of pain that a person can experience. Everybody experiences a headache at some time in their life. Most headaches are a mere annoyance and not a serious health concern, but that does not mean that you should never see a doctor for a headache. Here are the most common causes of headaches, and how to tell when it's time to see a neurologist / headache specialist. 



Tension headache - The most common headache type is the tension headache. These headaches are painful and annoying, but not usually incapacitating. They can be worsened in times of stress, so you may need to reduce the amount of stress in your life if you're getting a lot of tension headaches. Most of the time, tension headaches can be relieved with over-the-counter pain medications. Rarely, a person may have chronic tension headaches.


Migraine Unlike a Tension Headache, a migraine is usually incapacitating. In addition to severe headache pain, a person with...

1. Emotional stress is a common trigger of migraines. While it’s impossible to completely avoid stress, relaxation exercises can help you cope. Inhale and exhale slowly, letting the air fill you and then deflate like a balloon. Some people find that thinking of a peaceful scene or listening to favorite music can help.


2. Migraines may be set off by some specific cause, such as flickering lights. This could be a reflection from snow or water or from fluorescent bulbs or television or movie screens. Wearing polarizing sunglasses outside and using daylight spectrum fluorescent bulbs inside may help.


3. It’s important for people prone to migraines to have a regular pattern of meals and sleep. Low blood sugar from skipping meals can trigger a migraine. Eating too much sugar also can cause a spike, then a “crash” in blood sugar. Drink water throughout the day to avoid dehydration and sleep at least six to eight hours a night.


4. For many women, migraines are tied to their menstrual cycle, oc...

A migraine headache can cause intense throbbing or a pulsing sensation in one area of the head and is commonly accompanied by nausea, vomiting, and extreme sensitivity to light and sound. Migraine attacks can cause significant pain for hours to days and be so severe that all you can think about is finding a dark, quiet place to lie down. Some migraines are preceded or accompanied by sensory warning symptoms (aura), such as flashes of light, blind spots, or tingling in your arm or leg.


“Migraine is three times more common in women than in men” according to Dr Winnie Lim Khoo, Adult Neurologist in Manila, Philippines. Some people can tell when they are about to have a migraine because they see flashing lights or zigzag lines or they temporarily lose their vision. About 5% of the children with headache problems suffer from migraines. Both boys and girls can get migraines, but after puberty they are more common among girls. 


When untreated, a migraine usually lasts from four to 72 hours, b...

Heatstroke may appear similar to heat exhaustion, but the skin may be dry with no sweating and the person’s mental condition worsens. They may stagger, appear confused, fit, collapse and become unconscious.

Warning signs of heatstroke vary, but may include:

  • Very high body temperature

  • Red, hot, dry skin (no sweating)

  • Dry swollen tongue

  • Rapid pulse

  • Throbbing headache

  • Dizziness, confusion, nausea

  • Collapse

  • Eventual unconsciousness.

The best defense against any heat-related illness is prevention. If you take precautions and know the warning signs, you generally can prevent heat stoke. Keep a close watch on the elderly and infants, people on certain medications, athletes and outdoor workers. #heatstroke #heatindex #headache #stroke #neurologist #manila #philippines #winnielimkhoo

Here are a couple of suggestions for preventing heatstroke:

  • Drink plenty of water or other cool, non-alcoholic fluids even if you’re not thirsty (check with your doctor if you are on limited fluids or fluid pills.)

  • Plan ahead. Reduce activity and avoid exercise in hot weather. If activity is unavoidable, try to schedule it for the cooler part of the day and rest often. Whenever possible, stay indoors or in the shade.

  • Stay cool and keep air circulating around you. Draw your blinds or curtains and use a fan or air conditioning if possible. If you don’t have air conditioning, consider visiting an air-conditioned shopping mall or public place.

  • Eat smaller meals more often and cold meals such as salad.

  • Wear light-coloured, loose-fitting clothing made from natural fibres like cotton and linen.

  • Keep yourself cool by using wet towels, putting your feet in cold water and taking cool showers.

  • Check in on older, sick and frail family, friends and neighbors who may...

Heatstroke is a condition caused by your body overheating, usually as a result of prolonged exposure to or physical exertion in high temperatures. This most serious form of heat injury, heatstroke can occur if your body temperature rises to 104 F (40 C) or higher.


Heatstroke requires emergency treatment. Untreated heatstroke can quickly damage your brain, heart, kidneys and muscles. The damage worsens the longer treatment is delayed, increasing your risk of serious complications or death. Heatstroke symptoms include:

  • High body temperature. A body temperature of 104 F (40 C) or higher is the main sign of heatstroke.

  • Altered mental state or behavior. Confusion, agitation, slurred speech, irritability, delirium, seizures and coma can all result from heatstroke.

  • Alteration in sweating. In heatstroke brought on by hot weather, your skin will feel hot and dry to the touch. However, in heatstroke brought on by strenuous exercise, your skin may feel moist.

  • Nausea and vomiting...

Caffeine Can Make You More Alert

There's no magic bullet to boost IQ or make you smarter -- but certain substances, like caffeine, can energize you and help you concentrate. Found in coffee, chocolate, energy drinks, and some medications, caffeine gives you that unmistakable wake-up buzz, though the effects are short-term. And more is often less: Overdo it on caffeine and it can make you jittery and uncomfortable.


Sugar Can Enhance Alertness

Sugar is your brain's preferred fuel source -- not table sugar, but glucose, which your body processes from the sugars and carbs you eat. That's why a glass of something sweet to drink can offer a short-term boost to memory, thinking, and mental ability. Have too much, though, and memory can be impaired -- along with the rest of you. Go easy on the sugar so it can enhance memory without packing on the pounds.


Eat Breakfast to Fuel Your Brain

Tempted to skip breakfast? Studies have found that eating breakfast may improve short-term memory and attention...

Everyone has memory gaps from time to time — the word that’s on the very tip of your tongue, or the house keys that aren’t where you swear you left them. Memory gaps and errors refer to the incorrect recall, or complete loss, of information in the memory system for a specific detail and/or event. Try 9 simple steps that can help keep your brain sharp:


1. Step It Up

A 30-minute daily walk is one of the best things you can do for your body, including your brain. Some studies suggest that physical activity also triggers the release of a protein called BDNF, which promotes healthy nerve cells in the brain. That could give your memory a boost.


2. Go Mediterranean

A healthy diet is always good for your brain, but one eating style in particular may be best for preserving memory. One study found people who closely followed this diet were nearly 20% less likely to develop thinking and memory problems than people who didn't stick to a Mediterranean eating plan.


3. Engage Your Brain
