Your autonomic nervous system is the part of your nervous system that controls involuntary actions, such as the beating of your heart and the widening or narrowing of your blood vessels. When something goes wrong in this system, it can cause serious problems, including

• Blood pressure problems
• Heart problems
• Trouble with breathing and swallowing
• Erectile dysfunction in men

Autonomic nervous system disorders can occur alone or as the result of another disease, such as Parkinson's disease, alcoholism and diabetes. Problems can affect either part of the system, as in complex regional pain syndromes, or all of the system. Some types are temporary, but many worsen over time. When they affect your breathing or heart function, these disorders can be life-threatening.

Some autonomic nervous system disorders get better when an underlying disease is treated. Often, however, there is no cure. In that case, the goal of treatment is to improve symptoms.

What are peripheral nerves?

Nerves are like wires that carry messages back and forth between your brain and your body. Your peripheral nerves branch off from your brain and spinal cord and connect to all parts of your body, including your muscles and organs. Peripheral nerves carry messages from your brain that control your movement, breathing, heartbeat, digestion, and more. They also carry messages from your body to your brain, so you can feel things, such as pain, heat, and cold.

What are peripheral nerve disorders?

Peripheral nerve disorders happen when one or more peripheral nerves are damaged. Damaged nerves may not carry messages correctly, or they may not work at all. As a result, you may have pain, trouble walking, or a variety of other problems, depending on which nerves are involved.

Peripheral nerve disorders are very common. There are more than 100 different types.

What causes peripheral nerve disorders?

Many things can damage nerves and lead to peripheral nerve disorders:

• Diabetes is the most common cause of peripheral nerve disorders. Most people with diabetes will develop diabetic nerve problems.
• Physical injury (trauma) that stretches, crushes, squeezes, cuts, or puts pressure on one or more nerves. Some examples of peripheral nerve disorders from physical injury include complex regional pain syndrome and brachial plexus injuries.
• Health conditions, including:
  • Certain cancers and their treatment (chemotherapy and radiation therapy).
  • Infections, such as HIV and Lyme disease.
  • Problems with blood or blood vessels.
  • Autoimmune diseases, such as rheumatoid arthritis and lupus.
  • Kidney or liver disease.
• Certain medicines.
• Contact with certain toxic substances, such as lead or mercury.
• Alcohol use disorder (AUD) and smoking.
• Vitamin imbalances, especially a lack of vitamin B12.
• Your genes, including changes in your genes or conditions that you inherit from your parents, such as Charcot-Marie-Tooth disease.

In certain cases, the cause of peripheral nerve disorder is not known.

What are the symptoms of peripheral nerve disorders?

The symptoms of peripheral nerve disorders depend on which nerves are affected, what is causing the damage, and how serious it is:

Symptoms may range from mild to very strong. They may develop quickly over days or slowly over months and years. But they are rarely life-threatening.

How are peripheral nerve disorders diagnosed?

To find out if you have a peripheral nerve disorder, your provider will:

• Ask about your medical history
• Ask about your family health history
• Do a physical exam
• Order tests, which may include:
  • Blood tests
  • Genetic tests
  • Nerve tests that measure:
    • Electrical activity in your nerves and muscles
    • How well your autonomic nerves are working
  • A biopsy of nerve or skin tissue
  • CT or MRI scan to see what may be pressing on your nerves

What are the treatments for peripheral nerve disorders?

It's important to treat any conditions that are causing nerve damage. In certain cases, that will allow your nerves to heal over time.

Treatment for symptoms depends on the type of peripheral nerve disorder you have, where it is, and how severe. Treatment options include:

• Braces or splints
• Over-the-counter patches and skin creams
• Prescription medicines
• Non-drug pain management, such as electrical stimulation or relaxation therapy
• Surgery to relieve pressure on a nerve

Can peripheral nerve disorders be prevented?

You can help prevent peripheral nerve disorders by:

• Managing health conditions that may cause nerve damage, especially diabetes
• Preventing falls and accidents
• Avoiding toxic substances
• Being careful to avoid repeated motions and body positions that press on your nerves
• Eating a balanced diet, exercising, limiting alcohol, and not smoking

The brain, spinal cord, and nerves make up the nervous system. Together they control all the workings of the body. When something goes wrong with a part of your nervous system, you can have trouble moving, speaking, swallowing, breathing, or learning. You can also have problems with your memory, senses, or mood.

There are more than 600 neurologic diseases. Major types include

• Diseases caused by faulty genes, such as Huntington's disease and muscular dystrophy
• Problems with the way the nervous system develops, such as spina bifida
• Degenerative diseases, where nerve cells are damaged or die, such as Parkinson's disease and Alzheimer's disease
• Diseases of the blood vessels that supply the brain, such as stroke
• Injuries to the spinal cord and brain
• Seizure disorders, such as epilepsy
• Cancer, such as brain tumors
• infections, such as meningitis

Huntington's disease (HD) is an inherited disease that causes certain nerve cells in the brain to waste away. People are born with the defective gene, but symptoms usually don't appear until middle age. Early symptoms of HD may include uncontrolled movements, clumsiness, and balance problems. Later, HD can take away the ability to walk, talk, and swallow. Some people stop recognizing family members. Others are aware of their environment and are able to express emotions.

If one of your parents has Huntington's disease, you have a 50 percent chance of getting it. A blood test can tell you if have the HD gene and will develop the disease. Genetic counseling can help you weigh the risks and benefits of taking the test.

There is no cure. Medicines can help manage some of the symptoms, but cannot slow down or stop the disease.

What is muscular dystrophy (MD)?

Muscular dystrophy (MD) is a group of more than 30 genetic diseases. They cause weakness of the muscles. Over time, the weakness gets worse and can cause trouble walking and doing daily activities. Some types of MD can also affect other organs.

What are the types of muscular dystrophy (MD)?

There are many different types of MD. Some of the more common types include:

• Duchenne muscular dystrophy, which is the most common childhood form. It is severe and affects boys more often than girls. The symptoms usually start between ages 3 and 6.
• Becker muscular dystrophy, which is similar to Duchenne but is less severe and gets worse more slowly. It often starts in the teenage years.
• Congenital muscular dystrophies, which are present at birth or before age 2. They can be mild or severe.
• Facioscapulohumeral muscular dystrophy, which often starts in the teenage years. At first, it affects the muscles of the face, shoulders, and upper arms.

Each of the types of MD can be different in many ways, such as:

• Who is more likely to get them
• Which muscles they affect
• When they appear, such as in infancy, childhood, middle age, or later
• What the symptoms are
• How serious the symptoms are
• How quickly they get worse
• Whether they run in families
• Whether they affect other organs

Even within the same type of MD, people can have different symptoms.

What causes muscular dystrophy (MD)?

MD is genetic, meaning that it caused by a change in one or more genes. Gene changes are also called gene variants or mutations. The gene changes in MD affect proteins that strengthen and protect muscles.

There are different gene changes that cause each type of MD. And sometimes people who have the same type of MD can have different gene changes.

Muscular dystrophy can run in families, or you can be the first in your family to have a muscular dystrophy.

How is muscular dystrophy (MD) diagnosed?

To find out if you or your child has MD, your health care provider may use:

• A medical and family history
• A physical exam
• Blood and urine tests, including genetic tests and tests for certain enzymes that may be released by damaged muscles
• Muscle biopsies
• Electromyography and nerve conduction studies to find out if muscles are responding the right way to nerve signals
• Heart testing, such as an electrocardiogram (EKG), since some types of MD can cause heart problems
• Exercise tests to measure muscle strength and breathing and detect any increased rates of certain chemicals following exercise
• Imaging tests such as an MRI to look at muscle quality and bulk and measure fatty replacement of muscle tissue

What are the treatments for muscular dystrophy (MD)?

There is no cure for muscular dystrophy. Treatment can help with the symptoms and prevent complications. It usually includes a combination of therapies, such as:

• Physical therapy to help keep muscles flexible and strong
• Occupational therapy to relearn lost motor skills and learn ways to work around weakened muscles
• Respiratory care, such as breathing exercises, oxygen therapy, and ventilators
• Speech therapy to help with speech and swallowing problems
• Assistive devices, such as wheelchairs, splints and braces, and walkers
• Medicines to help delay damage to muscles or minimize the symptoms of MD
• Surgery to treat some of the conditions associated with MD, such as heart problems, scoliosis, and cataracts

Spina bifida is a neural tube defect - a type of birth defect of the brain, spine, or spinal cord. It happens if the spinal column of the fetus doesn't close completely during the first month of pregnancy. This can damage the nerves and spinal cord. Screening tests during pregnancy can check for spina bifida. Sometimes it is discovered only after the baby is born.

The symptoms of spina bifida vary from person to person. Most people with spina bifida are of normal intelligence. Some people need assistive devices such as braces, crutches, or wheelchairs. They may have learning difficulties, urinary and bowel problems, or hydrocephalus, a buildup of fluid in the brain.

The exact cause of spina bifida is unknown. It seems to run in families. Taking folic acid can reduce the risk of having a baby with spina bifida. It's in most multivitamins. Women who could become pregnant should take it daily.

What is a stroke?

A stroke happens when there is a loss of blood flow to part of the brain. Your brain cells cannot get the oxygen and nutrients they need from blood, and they start to die within a few minutes. This can cause lasting brain damage, long-term disability, or even death.

If you think that you or someone else is having a stroke, call 911 right away. Immediate treatment may save someone's life and increase the chances for successful rehabilitation and recovery.

What are the types of stroke?

There are two types of stroke:

• Ischemic stroke is caused by a blood clot that blocks or plugs a blood vessel in the brain. This is the most common type; about 80% of strokes are ischemic.
• Hemorrhagic stroke is caused by a blood vessel that breaks and bleeds into the brain

Another condition that's similar to a stroke is a transient ischemic attack (TIA). It's sometimes called a "mini-stroke." TIAs happen when the blood supply to the brain is blocked for a short time. The damage to the brain cells isn't permanent, but if you have had a TIA, you are at a much higher risk of having a stroke.

Who is at risk for a stroke?

Certain factors can raise your risk of a stroke. The major risk factors include

• High blood pressure. This is the primary risk factor for a stroke.
• Diabetes.
• Heart diseases. Atrial fibrillation and other heart diseases can cause blood clots that lead to stroke.
• Smoking. When you smoke, you damage your blood vessels and raise your blood pressure.
• A personal or family history of stroke or TIA.
• Age. Your risk of stroke increases as you get older.
• Race and ethnicity. African Americans have a higher risk of stroke.

There are also other factors that are linked to a higher risk of stroke, such as

• Alcohol and illegal drug use
• Not getting enough physical activity
• High cholesterol
• Unhealthy diet
• Having obesity

What are the symptoms of stroke?

The symptoms of stroke often happen quickly. They include

• Sudden numbness or weakness of the face, arm, or leg (especially on one side of the body)
• Sudden confusion, trouble speaking, or understanding speech
• Sudden trouble seeing in one or both eyes
• Sudden difficulty walking, dizziness, loss of balance or coordination
• Sudden severe headache with no known cause

If you think that you or someone else is having a stroke, call 911 right away.

How are strokes diagnosed?

To make a diagnosis, your health care provider will

• Ask about your symptoms and medical history
• Do a physical exam, including a check of
  • Your mental alertness
  • Your coordination and balance
  • Any numbness or weakness in your face, arms, and legs
  • Any trouble speaking and seeing clearly
• Run some tests, which may include
  • Diagnostic imaging of the brain, such as a CT scan or MRI
  • Heart tests, which can help detect heart problems or blood clots that may have led to a stroke. Possible tests include an electrocardiogram (EKG) and an echocardiography.

What are the treatments for stroke?

Treatments for stroke include medicines, surgery, and rehabilitation. Which treatments you get depend on the type of stroke and the stage of treatment. The different stages are

• Acute treatment, to try to stop a stroke while it is happening
• Post-stroke rehabilitation, to overcome the disabilities caused by the stroke
• Prevention, to prevent a first stroke or, if you have already had one, prevent another stroke

Acute treatments for ischemic stroke are usually medicines:

• You may get tPA, (tissue plasminogen activator), a medicine to dissolve the blood clot. You can only get this medicine within 4 hours of when your symptoms started. The sooner you can get it, the better your chance of recovery.
• If you cannot get that medicine, you may get medicine that helps stop platelets from clumping together to form blood clots. Or you may get a blood thinner to keep existing clots from getting bigger.
• If you have carotid artery disease, you may also need a procedure to open your blocked carotid artery

Acute treatments for hemorrhagic stroke focus on stopping the bleeding. The first step is to find the cause of bleeding in the brain. The next step is to control it:

• If high blood pressure is the cause of bleeding, you may be given blood pressure medicines.
• If an aneurysm if the cause, you may need aneurysm clipping or coil embolization. These are surgeries to prevent further leaking of blood from the aneurysm. It also can help prevent the aneurysm from bursting again.
• If an arteriovenous malformation (AVM) is the cause of a stroke, you may need an AVM repair. An AVM is a tangle of faulty arteries and veins that can rupture within the brain. An AVM repair may be done through
  • Surgery
  • Injecting a substance into the blood vessels of the AVM to block blood flow
  • Radiation to shrink the blood vessels of the AVM

Stroke rehabilitation can help you relearn skills you lost because of the damage. The goal is to help you become as independent as possible and to have the best possible quality of life.

Prevention of another stroke is also important, since having a stroke increases the risk of getting another one. Prevention may include heart-healthy lifestyle changes and medicines.

Can strokes be prevented?

If you have already had a stroke or are at risk of having a stroke, you can make some heart-healthy lifestyle changes to try to prevent a future stroke:

• Eating a heart-healthy diet
• Aiming for a healthy weight
• Managing stress
• Getting regular physical activity
• Quitting smoking
• Managing your blood pressure and cholesterol levels

If these changes aren't enough, you may need medicine to control your risk factors.

A stroke is a medical emergency. There are two types - ischemic and hemorrhagic. Ischemic stroke is the most common type. It is usually caused by a blood clot that blocks or plugs a blood vessel in the brain. This keeps blood from flowing to the brain. Within minutes, brain cells begin to die. Another cause is stenosis, or narrowing of the artery. This can happen because of atherosclerosis, a disease in which plaque builds up inside your arteries. Transient ischemic attacks (TIAs) occur when the blood supply to the brain is interrupted briefly. Having a TIA can mean you are at risk for having a more serious stroke.

Symptoms of stroke are

• Sudden numbness or weakness of the face, arm or leg (especially on one side of the body)
• Sudden confusion, trouble speaking or understanding speech
• Sudden trouble seeing in one or both eyes
• Sudden trouble walking, dizziness, loss of balance or coordination
• Sudden severe headache with no known cause

It is important to treat strokes as quickly as possible. Blood thinners may be used to stop a stroke while it is happening by quickly dissolving the blood clot. Post-stroke rehabilitation can help people overcome disabilities caused by stroke damage.

A stroke is a medical emergency. There are two types - ischemic and hemorrhagic. Hemorrhagic stroke is the less common type. It happens when a blood vessel breaks and bleeds into the brain. Within minutes, brain cells begin to die. Causes include a bleeding aneurysm, an arteriovenous malformation (AVM), or an artery wall that breaks open.

Symptoms of stroke are

• Sudden numbness or weakness of the face, arm or leg (especially on one side of the body)
• Sudden confusion, trouble speaking or understanding speech
• Sudden trouble seeing in one or both eyes
• Sudden trouble walking, dizziness, loss of balance or coordination
• Sudden severe headache with no known cause

It is important to treat strokes as quickly as possible. With a hemorrhagic stroke, the first steps are to find the cause of bleeding in the brain and then control it. Surgery may be needed. Post-stroke rehabilitation can help people overcome disabilities caused by stroke damage.

What is traumatic brain injury (TBI)?

Traumatic brain injury (TBI) is a sudden injury that causes damage to the brain. It may happen when there is a blow, bump, or jolt to the head. This is a closed head injury. A TBI can also happen when an object penetrates the skull. This is a penetrating injury.

Symptoms of a TBI can be mild, moderate, or severe. Concussions are a type of mild TBI. The effects of a concussion can sometimes be serious, but most people completely recover in time. More severe TBI can lead to serious physical and psychological symptoms, coma, and even death.

What causes traumatic brain injury (TBI)?

The main causes of TBI depend on the type of head injury:

• Some of the common causes of a closed head injury include
  • Falls. This is the most common cause in adults age 65 and older.
  • Motor vehicle crashes. This is the most common cause in young adults.
  • Sports injuries
  • Being struck by an object
  • Child abuse. This is the most common cause in children under age 4.
  • Blast injuries due to explosions
• Some of the common causes of a penetrating injury include
  • Being hit by a bullet or shrapnel
  • Being hit by a weapon such as a hammer, knife, or baseball bat
  • A head injury that causes a bone fragment to penetrate the skull

Some accidents such as explosions, natural disasters, or other extreme events can cause both closed and penetrating TBI in the same person.

Who is at risk for traumatic brain injury (TBI)?

Certain groups are at higher risk of TBI:

• Men are more likely to get a TBI than women. They are also more likely to have serious TBI.
• Adults aged 65 and older are at the greatest risk for being hospitalized and dying from a TBI

What are the symptoms of traumatic brain injury (TBI)?

The symptoms of TBI depend on the type of injury and how serious the brain damage is.

The symptoms of mild TBI can include:

• A brief loss of consciousness in some cases. However, many people with mild TBI remain conscious after the injury.
• Headache
• Confusion
• Lightheadedness
• Dizziness
• Blurred vision or tired eyes
• Ringing in the ears
• Bad taste in the mouth
• Fatigue or lethargy
• A change in sleep patterns
• Behavioral or mood changes
• Trouble with memory, concentration, attention, or thinking

If you have a moderate or severe TBI, you may have those same symptoms. You may also have other symptoms such as:

• A headache that gets worse or does not go away
• Repeated vomiting or nausea
• Convulsions or seizures
• Not being able to wake up from sleep
• Larger than normal pupil (dark center) of one or both eyes. This is called dilation of the pupil.
• Slurred speech
• Weakness or numbness in the arms and legs
• Loss of coordination
• Increased confusion, restlessness, or agitation

How is traumatic brain injury (TBI) diagnosed?

If you have a head injury or other trauma that may have caused a TBI, you need to get medical care as soon as possible. To make a diagnosis, your health care provider:

• Will ask about your symptoms and the details of your injury
• Will do a neurologic exam
• May do imaging tests, such as a CT scan or MRI
• May use a tool such as the Glasgow coma scale to determine how severe the TBI is. This scale measures your ability to open your eyes, speak, and move.
• May do neuropsychological tests to check how your brain is functioning

What are the treatments for traumatic brain injury (TBI)?

The treatments for TBI depend on many factors, including the size, severity, and location of the brain injury.

For mild TBI, the main treatment is rest. If you have a headache, you can try taking over-the-counter pain relievers. It is important to follow your health care provider's instructions for complete rest and a gradual return to your normal activities. If you start doing too much too soon, it may take longer to recover. Contact your provider if your symptoms are not getting better or if you have new symptoms.

For moderate to severe TBI, the first thing health care providers will do is stabilize you to prevent further injury. They will manage your blood pressure, check the pressure inside your skull, and make sure that there is enough blood and oxygen getting to your brain.

Once you are stable, the treatments may include:

• Surgery to reduce additional damage to your brain, for example to
  • Remove hematomas (clotted blood)
  • Get rid of damaged or dead brain tissue
  • Repair skull fractures
  • Relieve pressure in the skull
• Medicines to treat the symptoms of TBI and to lower some of the risks associated with it, such as
  • Anti-anxiety medication to lessen feelings of nervousness and fear
  • Anticoagulants to prevent blood clots
  • Anticonvulsants to prevent seizures
  • Antidepressants to treat symptoms of depression and mood instability
  • Muscle relaxants to reduce muscle spasms
  • Stimulants to increase alertness and attention
• Rehabilitation therapies, which can include therapies for physical, emotional, and cognitive difficulties:
  • Physical therapy, to build physical strength, coordination, and flexibility
  • Occupational therapy, to help you learn or relearn how to perform daily tasks, such as getting dressed, cooking, and bathing
  • Speech therapy, to help you to with speech and other communication skills and treat swallowing disorders
  • Psychological counseling, to help you learn coping skills, work on relationships, and improve your emotional well-being
  • Vocational counseling, which focuses on your ability to return to work and deal with workplace challenges
  • Cognitive therapy, to improve your memory, attention, perception, learning, planning, and judgment

Some people with TBI may have permanent disabilities. A TBI can also put you at risk for other health problems such as anxiety, depression, and post-traumatic stress disorder. Treating these problems can improve your quality of life.

Can traumatic brain injury (TBI) be prevented?

There are steps you can take to prevent head injuries and TBIs:

• Always wear your seatbelt and use car seats and booster seats for children
• Never drive under the influence of drugs or alcohol
• Wear a properly fitting helmet when riding a bicycle, skateboarding, and playing sports like hockey and football
• Prevent falls by
  • Making your house safer. For example, you can install railings on the stairs and grab bars in the tub, get rid of tripping hazards, and use window guards and stair safety gates for young children.
  • Improving your balance and strength with regular physical activity

A concussion is a type of brain injury. It involves a short loss of normal brain function. It happens when a hit to the head or body causes your head and brain to move rapidly back and forth. This sudden movement can cause the brain to bounce around or twist in the skull, creating chemical changes in your brain. Sometimes it can also stretch and damage your brain cells.

Sometimes people call a concussion a "mild" brain injury. It is important to understand that while concussions may not be life-threatening, they can still be serious.

Concussions are a common type of sports injury. Other causes of concussions include blows to the head, bumping your head when you fall, being violently shaken, and car accidents.

Symptoms of a concussion may not start right away; they may start days or weeks after the injury. Symptoms may include a headache or neck pain. You may also have nausea, ringing in your ears, dizziness, or tiredness. You may feel dazed or not your normal self for several days or weeks after the injury. Consult your health care professional if any of your symptoms get worse, or if you have more serious symptoms such as

• Convulsions or seizures
• Drowsiness or inability to wake up
• A headache that gets worse and does not go away
• Weakness, numbness, or decreased coordination
• Repeated vomiting or nausea
• Confusion
• Slurred speech
• Loss of consciousness

To diagnose a concussion, your health care provider will do a physical exam and will ask about your injury. You will most likely have a neurological exam, which checks your vision, balance, coordination, and reflexes. Your health care provider may also evaluate your memory and thinking. In some cases, you may also have a scan of the brain, such as a CT Scan or an MRI. A scan can check for bleeding or inflammation in the brain, as well as skull fractures.

Most people recover fully after a concussion, but it can take some time. Rest is very important after a concussion because it helps the brain to heal. In the very beginning, you may need to limit physical activities or activities that involve a lot of concentration, such as studying, working on the computer, or playing video games. Doing these may cause concussion symptoms (such as headache or tiredness) to come back or get worse. Then when your health care provider says that it is ok, you can start to return to your normal activities slowly.

Your spinal cord is a bundle of nerves that runs down the middle of your back. It carries signals back and forth between your body and your brain. A spinal cord injury disrupts the signals. Spinal cord injuries usually begin with a blow that fractures (breaks) or dislocates your vertebrae, the bone disks that make up your spine. Most injuries don't cut through your spinal cord. Instead, they cause damage when pieces of vertebrae tear into cord tissue or press down on the nerve parts that carry signals.

Spinal cord injuries can be complete or incomplete. With a complete spinal cord injury, the cord can't send signals below the level of the injury. As a result, you are paralyzed below the injury. With an incomplete injury, you have some movement and sensation below the injury.

A spinal cord injury is a medical emergency. Immediate treatment can reduce long-term effects. Treatments may include medicines, braces or traction to stabilize the spine, and surgery. Later treatment usually includes medicines and rehabilitation therapy. Mobility aids and assistive devices may help you to get around and do some daily tasks.

Epilepsy is a brain disorder that causes people to have recurring seizures. The seizures happen when clusters of nerve cells, or neurons, in the brain send out the wrong signals. People may have strange sensations and emotions or behave strangely. They may have violent muscle spasms or lose consciousness.

Epilepsy has many possible causes, including illness, brain injury, and abnormal brain development. In many cases, the cause is unknown.

Doctors use brain scans and other tests to diagnose epilepsy. It is important to start treatment right away. There is no cure for epilepsy, but medicines can control seizures for most people. When medicines are not working well, surgery or implanted devices such as vagus nerve stimulators may help. Special diets can help some children with epilepsy. 

A brain tumor is a growth of abnormal cells in the tissues of the brain. Brain tumors can be benign, with no cancer cells, or malignant, with cancer cells that grow quickly. Some are primary brain tumors, which start in the brain. Others are metastatic, and they start somewhere else in the body and move to the brain.

Brain tumors can cause many symptoms. Some of the most common are:

• Headaches, often in the morning
• Nausea and vomiting
• Changes in your ability to talk, hear, or see
• Problems with balance or walking
• Problems with thinking or memory
• Feeling weak or sleepy
• Changes in your mood or behavior
• Seizures

Doctors diagnose brain tumors by doing a neurologic exam and tests including an MRI, CT scan, and biopsy. Treatment options include watchful waiting, surgery, radiation therapy, chemotherapy, and targeted therapy. Targeted therapy uses drugs or other substances that attack cancer cells with less harm to normal cells. Many people get a combination of treatments.
