Stroke is a condition that occurs when the blood supply to the brain is disrupted or reduced due to blockage (ischemic stroke) or rupture of blood vessels (hemorrhagic stroke). Without blood, the brain will not get oxygen and nutrients, so cells in some areas of the brain will die. This condition causes the body parts that are controlled by damaged areas of the brain to not function properly.

Stroke is a medical emergency because brain cells can die in just minutes. Quick handling measures can minimize the level of brain damage and possible complications.

Every part of the body is controlled by different parts of the brain, so the symptoms of a stroke depend on the part of the brain that is affected and the level of damage. Symptoms or signs of stroke vary in each person, but generally appear suddenly. There are 3 main symptoms of stroke that are easy to remember, namely:

• Face. The face will look down on one side and unable to smile because the mouth or eyes droop.
• Arms (arms). People with symptoms of stroke cannot lift one of their arms because they feel weak or numb. Not only the arms, the one side legs with the arms also experience weakness.
• Speech (how to talk). Speech is unclear, chaotic, or even unable to speak at all even though the sufferer looks conscious.

In addition, there are several other symptoms and signs of stroke that may appear, including:

• Nausea and vomiting.
• Severe headaches that come suddenly, accompanied by stiffness in the neck and dizzy spin (vertigo).
• Loss of consciousness.
• Difficulty swallowing (dysphagia), resulting in choking.
• Disorders of balance and coordination.
• Sudden loss of vision or double vision.

Based on the cause, there are two types of strokes, namely:

Ischemic stroke. About 80% of strokes are a type of ischemic stroke. Ischemic stroke occurs when arterial blood vessels that carry blood and oxygen to the brain experience constriction or blockage, which causes blood flow to the brain to be greatly reduced. This condition is also called ischemia. Ischemic stroke can be divided into 2 types, including:

• Thrombotic stroke, a stroke that occurs when a blood clot forms in one of the arteries that supplies blood to the brain. The formation of blood clots is caused by fat deposits or plaques that accumulate in the arteries (atherosclerosis) and cause decreased blood flow.
• Embolic stroke, which is a stroke that occurs when a blood clot or clot that forms in another part of the body, generally the heart, is carried through the bloodstream and lodged in the blood vessels of the brain, causing the brain arteries to narrow. This type of blood clot is called an embolus. One of the heart rhythm disorders, namely atrial fibrillation, often causes embolic stroke.

Hemorrhagic stroke. Hemorrhagic stroke occurs when blood vessels in the brain rupture and cause bleeding. Bleeding in the brain can be triggered by several conditions that affect blood vessels. These conditions include:

• Uncontrolled hypertension.
• Weakening of blood vessel walls (brain aneurysm).
• Treatment with anticoagulants (blood thinners).

There are two types of hemorrhagic strokes, including:

• Intracerebral hemorrhage. In intracerebral hemorrhage, the blood vessels in the brain rupture and spill its contents into surrounding brain tissue, damaging brain cells.
• Subarachnoid hemorrhage. In subarachnoid hemorrhage, arterial arteries that are near the surface of the brain, rupture and spill its contents into the subarachnoid cavity, namely the space between the surface of the brain and the skull.

Stroke causes various serious effects on health, one of which is the brain. Brain damage due to stroke occurs due to a disturbed and not smooth blood supply. The effects of stroke on the brain that can cause damage to cells in the brain that cause interference with the senses, motor skills, behavior, language skills, memory, and the speed of stimulation in response to something. So, what happens to the brain when someone has a stroke?

Why can a stroke cause brain damage?

The brain needs a blood supply to keep working properly. Well, if the blood flow is insufficient, the condition and work of the brain changes. Here are some things that cause brain damage due to stroke.

1. Inflammation

When poisons attack the brain during a stroke, naturally these organs will try to repair themselves. However, not infrequently this business can actually cause excessive inflammation.

As a result, brain tissue will be flooded with fluids and white blood cells that are responsible for fighting infection. Well, this condition can cause swelling (edema) which can damage normal brain function.

2. Excess calcium and lack of sodium

When the brain is damaged by a stroke, calcium in the body can leak and enter brain cells. When the blood supply to the brain is insufficient the sign of oxygen intake decreases.

As a result, calcium levels become unbalanced. Meanwhile, brain cells are designed not to respond to large amounts of calcium. As a result, brain damage cannot be avoided.

In addition, sodium also functions to maintain normal brain function. But when a stroke strikes, sodium in the brain becomes unbalanced until it can change the contents of brain cells and make them damaged.

3. The formation of free radicals

Meanwhile, other factors that contribute to brain damage during stroke are free radicals. Free radicals produced during a stroke can quickly damage the tissue nearby. If that happens, even healthy brain cells will be affected and experience malfunction.

4. pH imbalance

Brain cells that do not get a blood supply that makes the brain experience a lack of energy to carry out its functions. As a result this will trigger the formation of strong acid molecules that can affect the pH of the brain. Excess acid molecules can be dangerous and can cause brain injury.

Various changes that occur due to post-stroke brain damage

Generally, stroke only affects one side of the brain. That means if a stroke attacks the left side of the brain, then you will experience various problems with the right side of your body and vice versa.

However, not infrequently strokes can also affect both sides of the brain. The effects of stroke on the brain will usually cause a loss of normal function in some parts of the body. The effect produced will vary according to which brain regions are affected, whether in the cerebrum (right and left brain), cerebellum (upper and front brain), and brainstem (brain stem).

Quoted from Hopkinsmedicine.org, here are various changes that occur due to post-stroke brain damage according to the affected part.

Cerebrum (right and left brain)

The following are the effects of stroke on the right and left brain, including:

• Having problems in moving the body.
• Cognitive disorders such as the process of thinking and memory.
• Having problems with language skills.
• Difficulty eating and swallowing.
• Visual impairment.
• Disorders of sexual ability.
• Problems with bowel and bladder control.

Cerebellum (upper and front brain)

The following are the effects of upper and front strokes in the brain, including:

• Problems of coordination and balance.
• Dizzy
• Headache
• Nausea and vomiting
• Brainstem (brain stem)

The following are the effects of stroke on the brain stem, including:

• Problems with breathing and heart function.
• The inability of the body to control temperature.
• Problems with balance and coordination.
• Difficulty chewing, swallowing, and talking.
• Visual impairment.
