The Two Types Of Stroke: Ischemic & Hemorrhagic

There are two types of stroke:

transient ischemic attack (TIA) is sometimes called a “mini-stroke.” It is different from the major types of stroke, because blood flow to the brain is blocked for only a short time—usually no more than 5 minutes.1

Ischemic stroke

Most strokes are ischemic strokes.2 An ischemic stroke occurs when blood clots or other particles block the blood vessels to the brain.

Fatty deposits called plaque can also cause blockages by building up in the blood vessels.

Hemorrhagic stroke

A hemorrhagic stroke happens when an artery in the brain leaks blood or ruptures (breaks open). The leaked blood puts too much pressure on brain cells, which damages them.

High blood pressure and aneurysms—balloon-like bulges in an artery that can stretch and burst—are examples of conditions that can cause a hemorrhagic stroke.

Transient ischemic attack (TIA or “mini-stroke”)

For Blanche Teal-Cruise, a smoker for 40 years who also had high blood pressure, the transient ischemic attack (sometimes called a mini-stroke) she had on the way to work was a wake-up call. Read Blanche’s story.

TIAs are sometimes known as “warning strokes.” It is important to know that

  • A TIA is a warning sign of a future stroke.
  • A TIA is a medical emergency, just like a major stroke.
  • Strokes and TIAs require emergency care. Call 9-1-1 right away if you feel signs of a stroke or see symptoms in someone around you.
  • There is no way to know in the beginning whether symptoms are from a TIA or from a major type of stroke.
  • Like ischemic strokes, blood clots often cause TIAs.
  • More than a third of people who have a TIA and don’t get treatment have a major stroke within 1 year. As many as 10% to 15% of people will have a major stroke within 3 months of a TIA.1

Recognizing and treating TIAs can lower the risk of a major stroke. If you have a TIA, your health care team can find the cause and take steps to prevent a major stroke.

Stroke: Long Periods Of Sitting Increases Risks

The study involved 7,607 adults who wore a hip-mounted accelerometer (a device that records how fast you move) for a week. Their average age was 63. During a follow-up period averaging 7.4 years, 246 of the participants experienced a stroke.

People who sat for 13 or more hours per day during the initial week of motion tracking were 44% more likely to have a stroke compared with those who’d spent less than 11 hours per day sitting still. In addition, longer bouts of sitting (more than 17 minutes at a time) were linked to a higher risk than shorter bouts (less than eight minutes).

Brain Health: The Benefits Of Intermittent Fasting

Although intermittent fasting is most widely known as a weight-loss strategy, emerging research suggests that it could have benefits for brain health and cognition. But does it actually work, are there any drawbacks and how long would you have to fast to see benefits?

WSJ’s Daniela Hernandez breaks down what’s known and what’s not about the neuroscience of intermittent fasting.

Cleveland Clinic: Primary Malignant Brain Tumors

A brain tumor is an abnormal growth or mass of cells in or around the brain. It is also called a central nervous system tumor. Tumors that develop in the brain are called primary tumors. Tumors that spread to the brain after forming in a different part of the body are called secondary tumors or metastatic tumors. This video focuses on primary malignant brain tumors.

Mayo Clinic: Treatments For Brain Aneurysms

Robert D. Brown Jr., M.D., M.P.H., E. Paul Lindell, M.D.,Giuseppe Lanzino, M.D., and Harry Cloft, M.D., Ph.D., explain what a brain aneurysm is and the different treatment options there are at Mayo Clinic for a patient with a brain aneurysm.

Mayo Clinic neurovascular experts care for 17,000 people each year with aneurysms, strokes, and other blood vessel and cerebrovascular conditions. Each brain aneurysm is unique. Your doctor will use state-of-the-art arterial imaging to evaluate, diagnose and assess the aneurysm’s risk of rupture.

Every patient has team of doctors working together to create an individualized path of care. Some aneurysms do not require surgery and are closely monitored instead.

Diet & Nutrition: Nine Healthy ‘Brain Food’ Tips

• Find time to snack healthily. Take short food breaks to help keep your blood-sugar level reasonably high without surging. Eating a piece of fruit every three hours or so, for example, could prevent hunger and overconsumption of calories. And when you eat, relax. Try not to think about your research. If you routinely stand in the lab, sit down. If your role is more sedentary, get up and take a quick stroll — perhaps to see a colleague on the next floor.

• Put food on your agenda. Schedule regular mealtimes in your work diary — because if you don’t, someone else will fill the gap for you by inviting you to a meeting. Choose a slot that aligns with your ‘biological clock’ and alterations in hormones such as insulin to optimize metabolic health, including microbiota diversity and composition. In other words, follow your gut and eat at times of the day when you feel that your body needs it, but generally try to avoid taking lunch too late in the afternoon. Eating earlier in the day can improve your energy balance, weight regulation, glycaemic control and sleep satisfaction6. Your brain consumes about 20% of the total energy used by your body, so maintaining consistent energy levels is important for optimal functioning. Use the time you’ve booked. Focus on what you eat and take your time. Do not grab a sandwich and munch it down in front of a screen. Your body deserves a rest.

• Enjoy your food. Transform your meal break into a pleasant event by sharing it with colleagues. Propose that everyone take turns preparing a dish from their home country or area so that you can all enjoy the cuisines of different cultures. Eating in a group and discussing the day’s events can help you to relax, to laugh and to share useful information and experiences.

• Plan your meals. If you are feeling particularly hungry, your eyes and hypothalamus (a small region in the brain that controls many bodily functions including hunger and thirst) will not help you to make healthy food choices; instead, they will prompt you to go for sugary, salty or fatty options. Try to organize your meals in advance. Increase your intake of low-calorie items, such as soups, salads, vegetables and minimally processed foods that are rich in dietary fibre. Among these are wholegrains, cereals, fruits, pulses, whole rice and wholemeal pasta. These foods are also rich in micronutrients and antioxidants such as potassium, magnesium, vitamin C, vitamin E, B-vitamins and healthy lipids — especially unsaturated omega-3 ones — that can help to prevent chronic disease. Neurotransmitters such as serotonin, dopamine, epinephrine and norepinephrine — all important for good brain function, mood and emotional regulation — require food-derived precursors, as well as vitamins and minerals, to be synthesized7.

• Diversify your diet. Stimulate your appetite by altering your food choices, preferably by incorporating more fruit and vegetables into your diet and reducing consumption of red meat and meat products. Each new day merits a new meal experience. But this doesn’t mean being a fully fledged connoisseur: overthinking what you eat will lead to compromises with your time and will make further compromises in what you eat more tempting. A saying from the Japanese Okinawa islands, where people have one of the lowest rates of chronic diseases in the world, and where many centenarians live, points the way: “Eat until you are 80% full”8. In practice, this means you should eat slowly and avoid ‘stuffing’ yourself.

• Avoid the insulin roller coaster. As well as contributing to chronic disease, excessive sugar intake might harm cognitive performance9. Sugared drinks, such as sodas, smoothies and even fruit juices, have a very low satiety value. After the sugar surge, glucagon — a hormone produced when sugar levels are low — as well as ghrelin, an appetitive hormone, and others kick back in and you’ll be hypoglycaemic and feel hungry again. Artificially sweetened beverages might not work much better — there is scientific debate about their perceived health benefits, because they might stimulate appetite centrally in the hypothalamus, rather than by modulating insulin levels10. Go for water, coffee, teas (including fruit teas), low-fat milk — or, if you’re desperate for sugar, a homemade fruit juice.

• Drink loads of water. Working inside, where the air is often dry (owing to heating in winter and artificial cooling in summer) can hasten water loss through respiration. Two litres a day of fluid intake is recommended by many health agencies. Pay attention to signs of dehydration. Drinking plenty will increase your blood volume and brain tissue fluid and thus boost your circulation and concentration levels. You will also become more tolerant of heat and cold — which is helpful when working in warm offices and cooled labs. Water is the essential carrier for all life functions in your body. It can also increase daily energy expenditure and feelings of satiety. Drinking water half an hour before your meal is an especially good option because it improves satiety11.

• Use healthy leftovers. Pre-packaged sandwiches and processed foods often have high quantities of fat, sugar, salt and additives that trigger the brain’s dopamine reward system, among other neuronal systems, inducing compulsive eating behaviour12. If you have time, prepare a healthy dish from scratch at home, perhaps making more than is needed for an evening meal and using leftovers for lunch the following day. Among homemade foods, well-balanced traditional dishes can improve your performance and health: for instance, the classic Mediterranean diet has long been linked with improved cognitive function and a decreased likelihood of both cognitive impairment and Alzheimer’s disease3. A Tupperware lunch made with leftovers from even the most indulgent dinner could often make a healthier lunch than a standard pre-packaged sandwich.

• Scrap the salt. Excessive use of salt is among the major killers worldwide, leading to increased blood pressure, stroke and other cardiovascular diseases. Some salt is essential to the taste of most foods, as well as for life, however, so don’t attempt to cut it out of your diet entirely. Try pepper, curcuma, nutmeg or other spices to add flavour. Some spices, including curcuma and pepper, also help to lower the risk of cardiovascular disease and can even decrease total mortality rates13.
