Sometimes people will experience a concussion. This is an injury to the
brain that is caused from . Symptoms from cw to the head or from a falloncussions
usually go away within one day. These symptoms can include nausea,
disorientation, dizziness, and even double vision or diplopia. If the concussion is severe enough it can cause a coma. This is an abnormal deep sleep
where the body responds very little, if at all, to external stimuli.
A more serious form of a concussion
is a cerebral contusion. During this
form of trauma, blood escapes from local vessels due to a bruise to the brain’s
surface. The bruising is on the surface and does not penetrate into the brain.
Symptoms from brain contusions can cause extreme disorientation and even death.
An even more serious form of trauma
is associated traumatic brain injuries. If the injury is traumatic enough
bleeding may occur around the meninges. This can cause a hematoma, which is the localized collection of clotted blood. Hematomas
result in gradual blood accumulation ha puts pressure on the brain. Depending
on the type of hematoma experienced, symptoms can range from a headache and
loss of consciousness to death.
is loss of neurons and scarring in brain tissue this can lead to a degenerative
disorder. These disorders occur because there is a progressive deterioration or
loss of function with neural tissues. Often these disorders are irreversible.
Degenerative disorders can affect a wide variety of the body’s activities like
talking, breathing, balance, and moving. Often these disorders are genetic but
a medical condition can lead to the onset of a degenerative disorder. Most
often the medical condition includes alcoholism, a tumor, or stroke. Even
exposure to certain toxins, chemicals, and viruses may lead to the development
of a degenerative disease. The following list describes some common types of
Multiple Sclerosis – this commonly attacks people between
the ages of 20-30. Once it attacks the body it progressively gets worse over
time. This progression takes place at intervals. The rate of progression varies
from person to person. When a person has multiple sclerosis there is damage
done to the myelin sheath. Instead wherever myelin should be there is a
hardening of tissue in the CNS. This replacement with hardened tissue disrupts
neural signaling between the brain and the body. Symptoms associated with
multiple sclerosis include vision problems, muscle weakness, trouble with
balance, tingling or numbness in arms and legs, tremors or shaking, and memory
Alzheimer’s Disease – this happens where there is a
degeneration of neurons in the brain that causes the cerebral cortex to atrophy
or waste away. This leads to symptoms such as memory loss, confusion, and mood
changes. All symptoms are progressive. This means over time symptoms develop
slowly and steadily get worse. Eventually they get severe enough to interfere with
everyday activities. Alzheimer’s is also known as a form of dementia. This is a general term that
refers to memory loss or other mental abilities that limit a person’s ability
to perform daily activities. Dementia is not a specific disease but a group of
symptoms caused b y disorders like Alzheimer’s.
