The Brain is part of the central nervous system, which is
composed of the spinal cord. Brain is one of the most important parts of
the body as it functions as a command center. The brain works with various
nerves to receive and send messages to different parts of the body and tell
what to do and how to do it.Our brain is an organ that is very soft and tough
and consists of various parts. The largest part is dominated by the cerebrum,
which controls speech, memory, and emotion. There is also a brain stem, which
has an important role in stressful situations. When a person is under pressure,
the brain enters a fight-or-flight mode, which is governed by the brain stem.
The brain also controls blood pressure and breathing. The small brain
(cerebellum) is the part of the brain that regulates movement, balance, and interpretation
of information sent by the human senses.
1. Causes
a. Hypertension
One of the main causes of cerebral hemorrhage is
hypertension, also known as high blood pressure. The heart pumps blood through
various blood vessels, such as arteries to drain oxygen and other nutrients to
cells and tissues. But in order for blood to flow, blood will require pressure
as it flows through the arteries. However, sometimes this pressure can be very
high. This will cause the blood vessels to become attracted and eventually
rupture, resulting in blood flowing out. In the United States, there are at
least 30% of people aged 20 years and over who are affected by hypertension.
b. Brain Injury
Another possible causes of cerebral hemorrhage are head
injury, especially traumatic brain injury. The skull is a hard part of the
head, but the skull does not have the ability to withstand too violent impacts.
Depending on the strength of impact on the head, the skull may crack, and the
injury may reach the brain. There is a possibility that the skull is not
cracked, but the brain may experience subdural hematoma, or bruising and
bleeding in some blood vessels located between layers of the brain. Brain injury
is very dangerous, especially for elderly patients. Minor injuries from a fall
or impact on the head can cause bleeding.
c. AVM
Last another conditions that can cause cerebral hemorrhage
are rare and occur in less than 1% of Americans are arteriovenous malformation
(AVM). This condition is characterized by the bounding of blood vessels and
arteries in the brain. Arteries carry oxygen-rich blood to the brain, while
blood vessels carry blood without oxygen to the heart, then to the lungs to
release carbon dioxide. Due to the bounding of blood vessels and arteries, the
function of both will be disrupted, so that the blood vessels will begin to
swell and eventually broke. AVM can occur at birth or when the patient is an
adult.
2. Main Symptoms of Brain Bleeding
There are some of symptoms of Brain bleeding :
- Headaches that occur suddenly and painfully
- Weakening of muscles or muscles stops working
- Not able to perform simple activities such as speaking correctly
- Mood swings
- Loss of memory
- Sensitivity to light
- Dizzy
- Paralyzed or numb
- Loss of vision
- Disorientation or confusion
- Stiff neck
- Feeling unwell
- Missing awareness
- Seizures
- Blurred vision
- Gag
There is the possibility of bleeding has occurred before the
symptoms arise. This usually occurs in patients who have high blood pressure/hypertension.
Because of this, hypertension is often referred as a killer disease.
