Your brain is the control center of your body. It is a part of the neurological system, a complex system that includes the spinal cord and a vast network of nerves and neurons that control and implement the functions you do every day. Brain disorders occur when your brain is damaged by injury, disease, or health conditions.
The symptoms of brain disorders
typically depend on the cause of the condition. Brain disorders may affect
the
main areas of your brain that control how you move, think, and behave. Some
tumors can constrict the blood vessels in your brain.
The following are some common
symptoms brain disorders may present:
- confusion or problems concentrating
- headaches or migraines
- seizures (convulsions)
- memory problems
- change in the way you normally behave
- problems with your vision (double vision, for example)
- lack of muscle control
- vomiting or nausea
The causes of brain disorders vary
with the type of disorder you experience
The following are causes of brain
disorders:
- trauma to the brain
- stroke (restricted or reduced oxygen and blood in the brain that leads to cellular death)
- viral infections (viruses may cause inflammation and swelling in the brain’s tissue)
- disease and cancer
- abnormal growths (tumors)
- inherited conditions that affect the brain
- change in your brain’s electrical pathways (communication between neurons)
You may be at risk for a brain
disorder if you:
- have blunt trauma to the head
- have a family history of brain disorders or disease
- have a viral infection
- have a stroke
- smoke tobacco products
- stop breathing (can prevent oxygen from reaching the brain)
There are many types of brain
disorders, and they can change the way your brain commands the rest of your
body.
Brain
Injuries
Brain injuries are often caused by
blunt trauma. Injury can damage tissue, neurons (messengers within the brain),
and nerves that transmit information from the brain to your body. This can
cause changes in how your brain communicates with the rest of your body.
Brain
Tumors
Tumors can develop in the brain’s
tissue and cause many problems, including preventing blood circulation in the
brain. These growths may be cancerous or benign.
Degenerative
Diseases
Degenerative diseases can affect the
brain in many ways. They can change your personality, cause confusion, or
destroy your brain’s tissue and nerves. Some brain diseases, such as
Alzheimer’s disease, may manifest as you age and slowly impair your memory and
thought processes. Other diseases, such as Tay-Sachs disease, begin at an early
age. Tay-Sachs disease affects a child’s mental and physical capabilities.
Mental
Health Conditions
Mental health conditions change your
behavior patterns. Certain types of mental health conditions may be chronic or
acute. Depression, anxiety, and bipolar disorder are three brain
disorders that may become chronic conditions.
Your primary physician may refer you
to a specialist in the neurological field. This specialist may perform a
neurological exam to check your vision, hearing, and balance.
The doctor might also use imaging
technology—such as a computed tomography (CT) scan—to take images of your
brain. Other diagnostic imaging tools include magnetic resonance imaging (MRI)
and positron emission tomography (PET).
In addition, your neurologist might
take and study fluid from your brain and spinal cord as a way to locate bleeding
in the brain, infection, and other abnormal occurrences.
Treatment is based on the doctor’s
findings, diagnosis, and your overall health. Your doctor might combine
treatments to improve your condition.
Medication
If you have swelling or inflammation
in your brain, medications to reduce these symptoms may be used.
For mental health and mood disorders,
such as depression, psychotropic drugs may be prescribed to control your
behavior.
For degenerative conditions that
cause the loss of muscle control and movement, drugs that help decrease the
symptoms may be options.
Surgery
Surgery may be used to remove a brain
tumor or damaged tissue or to drain excess fluid caused by infection. Sometimes
brain surgery is done to remove a sample of brain tissue or a tumor for
diagnostic purposes. The samples are examined for cancer, disease, and other
abnormal findings.
Your doctor may require follow-up
visits to monitor your health and to see how well your treatments are working.
Some brain disorders might require long-term care to manage the symptoms and to
prevent further complications.
