The brain is responsible for regulation the functions of the body, from the unconscious controlling blood pressure, heart rate and respiratory rate to the conscious acts like walking and talking.

Add the intellectual processes of thought and the brain is a busy part of the human body. The brain has many parts. The cerebrum consists of two hemispheres which are responsible for movement, sensation, thought, judgment, problem solving, and emotion.

The brain stem sits beneath the cerebrum and connects it to the spinal cord. The brain stem houses the structures that are responsible for the unconscious regulation of the body such as wakefulness, heart and lung function, hunger, temperature control, and swallowing.

The cerebellum is located beneath and behind the cerebrum and is responsible for posture, balance, and coordination. While the brainstem is important in maintaining body function, the cerebrum allows body motion and most importantly, is responsible for all the things that make humans special, like thinking and emotion.

There are four lobes in each hemisphere: Brain cells use glucose almost exclusively for their energy needs and unlike other organs in the body, the brain cannot store glucose for future use.

If blood sugar levels fall, brain lesions and cancer, brain function can be immediately compromised. The brain gets its blood supply through four major arteries, brain lesions and cancer right and left carotids and the right and left vertebral arteries.

They join together at the base of the brain at the Circle of Willis. Smaller blood vessels then branch out to provide oxygen and glucose rich blood to all regions of the brain. The brain brain lesions and cancer composed of billions of cells that use chemicals and electricity to communicate between themselves and the rest of the body.

There are two major types of cells, neurons and glial cells; there are subtypes of these cells. Benign brain tumors are usually defined as a group of similar cells that do not follow normal cell division and growth patterns and develop into a mass of cells that microscopically brain lesions and cancer not have the characteristic appearance of a cancer. These tumors usually grow slowly, brain lesions and cancer, do not invade surrounding tissues or spread to other organs, and often have a border or edge that can be seen on CT scans.

These tumors rarely develop children food allergies and behavior metastatic cancerous or spreading tumors.

Most benign brain tumors can be removed; the benign tumors usually do not reoccur after removal. The exact causes of benign brain tumors are not known, but investigators have suggested that family history, radiation exposure, or exposure to chemicals for example, brain lesions and cancer, vinyl chloride, formaldehyde may be risk factors.

What are diovan and drug interactions lesions? A brain lesion describes damage or destruction to any part of the brain.

It may be due to trauma or any other disease that can cause inflammation, malfunction, or destruction brain lesions and cancer a brain cells or brain tissue. A lesion may be localized to one part of the brain or they may be widespread.

The initial damage may be so small as to not produce any initial symptoms, brain lesions and cancer, but progresses over time to cause obvious physical and mental changes. A brain lesion may affect the neuron directly or one of the glial cells thereby indirectly affecting neuron functions.

What causes brain lesions? What are the types of brain lesions? There are many types of brain lesions. The brain can brain lesions and cancer affected by a host of potential injuries that can decrease its function. The type of lesion depends upon the type of insult that the brain receives. Some lesions occur as a result of aging with loss of brain cells as they naturally age and die.

If enough cells die, atrophy can occur and brain function decreases. This may present with symptoms of loss of memory, cancer and stroke judgment, loss of insight and general loss of mental agility.

Loss of brain cells also occurs with stroke. With ischemic strokes CVA blood supply to an area of the brain is lost, brain cells die and the part of the body brain lesions and cancer control loses its function. Strokes can also be hemorrhagic, where bleeding occurs in part of the brain, brain lesions and cancer, again damaging brain cells and causing loss of function.

Uncontrolled high blood pressurebrain lesions and cancer, AV malformations, and brain aneurysms are some causes of bleeding in the brain. Bleeding in the brain may be caused by trauma and a blow to the head. Bleeding may occur within brain tissue or in the spaces surrounding the brain.

Epidural and subdural hematomas describ blood clots that form in the spaces between the meninges or tissues that line the brain and spinal cord. As the clot expands, pressure increases within the skull and compresses brain lesions and cancer brain. Sometimes trauma can affect the brain with no evidence of bleeding on CT scan.

Acceleration deceleration injuries can cause significant damage to brain tissue and connections causing microscopic swelling. Infectious agents resulting in diseases such as meningitisbrain abscesses or encephalitis, brain lesions and cancer.

Tumors are types of brain lesions and may be benign meningiomas are the most common or malignant like glioblastoma multiforme. Tumors in the brain may also be metastatic, spreading from cancers that arise primarily from another organ.

Symptoms occur depending upon the location and size of the tumor. Immunologic causes may also affect the brain, for example diseases like multiple sclerosis. Toxins may affect brain function and may be produced within the body or may be ingested.

The most common ingested poison is alcohol, though other chemicals can adversely brain lesions and cancer the brain. Individuals can develop encephalopathy due to a variety of chemicals and substances that build up in the blood stream.

Ammonia levels rise in patients with liver failure while patients with kidney failure can become uremic. The type of lesion depends upon its cause and symptoms depend upon its location and amount of brain irritation or damage that has occurred.

Research is ongoing and is likely to provide better insights into these various brain lesion types. What are the signs and symptoms of brain lesions? Symptoms of a brain lesion depend upon what part of the brain is affected. Large parts of the brain can be involved in some diseases and there may be relatively few symptoms, brain lesions and cancer. Alternatively, very tiny lesions may be catastrophic if they occur in a critical part of the brain. If a midbrain stroke affects this area, the result is permanent coma.

A patient needs the RAS and one functioning hemisphere of the cortex to be awake. If any of these symptoms arise suddenly, the person should be evaluated immediately, usually in an emergency department that is well equipped CT scanner, MRI, easy access to neurosurgeons and neurologists.

How are brain lesions diagnosed? The diagnosis of a brain lesion begins with the health care practitioner taking a history and asking the patient questions about the symptoms such as:. Depending upon the circumstances, the patient may not have insight or may not remember the symptoms or complaints, and it may be up to a family member, caregiveror friend to supply the appropriate information. Past medical history of the brain lesions and cancer, exploring associated symptoms and complaints may be helpful in determining the diagnosis.

Physical examination is very helpful in trying to localize a potential brain lesion. A careful neurologic exam may be useful in finding weakness, change in sensation including light touch, painvibration, and position senseand coordination.

Mental status, agility, other organ systems are often assessed. For example, patients who have an irregular heart rate called atrial fibrillation are at risk for stroke.

Stroke risk may also be increased in patients with carotid stenosis and the health care practitioenr may listen over the neck for a bruit an abnormal sound made by blood rushing through a narrowed carotid artery.

Depending upon the clinical situation, imaging of the brain such as computerized tomography CT andmagnetic resonance imaging MRI may be useful in making the diagnosis of a brain lesion. Lumbar puncture spinal tap is often considered to evaluate the brain lesions and cancer fluid CSF for infection, bleeding, or abnormal proteins; depending upon the clinical situation.

Blood tests are usually preformed, to explore any illnesses that can also involve the brain. What is the treatment for brain lesions? Can brain lesions be prevented? Many brain lesions are neither preventable nor predictable.

However, general guidelines for health brain lesions and cancer may help brain lesions and cancer some brain lesions.

The same recommendations to help prevent heart disease also are appropriate to help prevent strokes:. What is the prognosis for brain lesions? The prognosis for surviving and recovering from a brain lesion depends upon the cause.

In general, brain lesions and cancer, many brain lesions have only a fair to poor prognosis because damage and destruction of brain tissue is frequently permanent. However, some people can reduce their symptoms with rehabilitation training and medication. Learn the warning brain lesions and cancer of dementia. CT scan computerized tomography is a procedure that uses X-rays to scan and take images of cross-sections of parts of the body.

CT scan brain lesions and cancer help diagnose broken bones, tumors or lesions in areas of the body, blood clots in the brain, legs, and lung, and lung infections or diseases like pneumonia or emphysema. MRI magnetic resonance imaging is a procedure that uses strong magnetic fields and radiofrequency energy to make images of parts of the body, particularly, brain lesions and cancer, the organs and soft tissues like tendons and cartilage.

Both CT and MRI are painless, however, MRI can be more bothersome to some individuals who are claustrophobic, or suffer from anxiety or panic disorders due to the enclosed space and noise the machine makes. Rheumatoid arthritis RA is an autoimmune disease that causes chronic inflammation of the joints, the tissue around the joints, as well as other organs in the body.

Because it can affect multiple other organs of the body, rheumatoid arthritis is referred to as a systemic illness and is sometimes called rheumatoid disease. A stroke is an interruption of the blood supply to part of the brain caused by either a blood clot brain lesions and cancer or bleeding hemorrhagic.

A physical exam, imaging tests, neurological exam, and blood tests may be used to diagnose a stroke. Treatment may include administration of clot-busting drugs, supportive care, and in some instances, brain lesions and cancer, neurosurgery. The risk of stroke can be reduced by controlling high blood pressure, high cholesterol, diabetes, and stopping smoking.
