How Do Neurologists Diagnose Conditions

The Doctor Is In: Brain Tumors

Your neurologist will ask about your medical history, family history, medication history and any current symptoms. Theyll also conduct a neurologic examination, including tests of your:

  • Coordination, balance, reflexes and gait.
  • Muscle strength.
  • Vision, hearing and speech.
  • Sensation.

Your neurologist may also order blood, urine or other fluid tests in order to help understand condition severity or check on medication levels. Genetic testing may be ordered to identify inherited disorders. Imaging studies of your nervous system might also be ordered to aid in diagnosis.

Neurologists treat people with medications, physical therapy or other approaches.

Some Key Neurotransmitters At Work

Neurotransmitters are chemicals that brain cells use to talk to each other. Some neurotransmitters make cells more active while others block or dampen a cell’s activity .

Acetylcholine is an excitatory neurotransmitter because it generally makes cells more excitable. It governs muscle contractions and causes glands to secrete hormones. Alzheimers disease, which initially affects memory formation, is associated with a shortage of acetylcholine.

Glutamate is a major excitatory neurotransmitter. Too much glutamate can kill or damage neurons and has been linked to disorders including Parkinson’s disease, stroke, seizures, and increased sensitivity to pain.

GABA is an inhibitory neurotransmitter that helps control muscle activity and is an important part of the visual system. Drugs that increase GABA levels in the brain are used to treat epileptic seizures and tremors in patients with Huntingtons disease.

Serotonin is a neurotransmitter that constricts blood vessels and brings on sleep. It is also involved in temperature regulation. Low levels of serotonin may cause sleep problems and depression, while too much serotonin can lead to seizures.

Dopamine is an inhibitory neurotransmitter involved in mood and the control of complex movements. The loss of dopamine activity in some portions of the brain leads to the muscular rigidity of Parkinsons disease. Many medications used to treat behavioral disorders work by modifying the action of dopamine in the brain.

What Does A Brain Mri Show

A brain or head MRI shows the structures inside of your head, including:

  • Your brain.
  • Blood vessels that connect to your brain.
  • Your skull and facial bones.
  • Structures in your inner ear.
  • Your eyes and their supporting tissues, such as your optic nerves.
  • Other nerves .
  • Surrounding soft tissues and skull-based structures, such as fat, bones, muscle and connective tissue.

More specifically, a brain or head MRI can show if there are any abnormalities in your brain or the surrounding tissues, including, but not limited to:

Healthcare providers also use brain and head MRI scans before surgeries involving your head to better prepare for the surgery. They also use these scans to ensure that healing from the surgery is going well. Any significant injuries involving your head also prompt healthcare providers to order brain MRI scans to check for injuries, bleeding and swelling.

What Is An Eye Doctor

An optometrist is an eye doctor who has actually made the Doctor of Optometry degree. Eye doctors analyze eyes for both vision and illness, and correct refractive errors by prescribing eyeglasses and contact lenses. Some eye doctors likewise supply low vision care and vision therapy.

Optometrists in the United States likewise are accredited to prescribe medications to treat particular eye problems and diseases. The scope of medical care that can be supplied by optometrists is determined by state law.

Optometrists also may take part in your pre- and post-operative care if you have eye surgery carried out by an ophthalmologist. With a couple of exceptions, eye doctors in the U.S. are not trained or licensed to perform eye surgery.

An eye doctor usually must finish a four-year college degree program in the sciences, plus four years of post-graduate expert training in optometry school. In this regard, the academic requirements of an optometrist resemble those of a dental expert.

Like ophthalmologists, eye doctors are required to satisfy continuing education requirements on a continuous basis to keep their licensure and stay current with the latest requirements of eye care.

Chronic Headaches Or Migraines

What Is A Brain Doctor Called

We all experience headaches of varying durations and severity due to everything from staring at a computer screen too long to loud noise to lack of sleep to a sinus infection. While painful, most headaches are temporary. Usually, conservative treatments like over-the-counter pain medications will provide relief.

See a neurologist in these instances:

  • Your headaches become severe or disabling.
  • Youre taking medication for headaches daily.
  • You routinely wake up with a headache.
  • Your headaches are accompanied by other neurological symptoms, such as vision changes, dizziness, nausea or even seizures .
  • Your headaches are severe and are accompanied by a sensitivity to light, strong smells or loud sounds, which could indicate migraines.

Your neurologist can help determine whats causing your headaches and any other symptoms and help you get relief.

In addition to prescribing medications or treatments like Botox, Zacharias emphasizes lifestyle modifications. I always share tips with my patients, she says. For instance, I tell them to stay hydrated, dont skip meals, avoid excessive caffeine and alcohol, engage in physical activity, and try relaxation therapy. All of those things can be helpful with headaches.

And if youre having migraines, your neurologist can help you identify and avoid your triggers including stress and certain foods to prevent them.

Which Conditions Do Neurosurgeons Treat

As mentioned above, neurosurgeons treat conditions associated with the brain, perform surgery on the brain itself, perform surgery on the neck/back area, and perform surgery on the spinal cord. Nearly any condition associated with those areas of the body, a neurosurgeon will be able to treat in some way, shape, or form.

What To Expect At Your Appointment

Your neurologist will ask all about your health history. You will also have a physical exam to test your coordination, reflexes, sight, strength, mental state, and sensation. The neurologist may order other tests such as:

  • MRI: This test uses magnetic fields and radio waves to take pictures of your inner brain. Youll lie down inside a machine for about 30 minutes.
  • Computerized Tomography or Computer-Assisted Tomography scans:X-rays and computers create multi-dimensional images of your body. A health care provider might inject dye to make arteries, blood vessels, tumors, or other areas visible in the image.
  • Electroencephalogram : Electrodes attached to your scalp record your brains electrical activity.
  • Transcranial Doppler : An ultrasound probe placed on your head measures blood flow in your brain by using sound waves.
  • Spinal Tap or Lumbar Puncture: A doctor numbs your back and removes spinal fluid with a needle. Doctors can then check for bleeding, infection, and other disorders.
  • Electromyogram : This test tracks electrical activity in your muscles and nerves to help find the cause of pain, numbness, and weakness. The doctor inserts small needles into your muscles to test activity. The doctor delivers mild shocks on the surface of your body to record nerve activity.

Neurology Tests And Procedures

How a Neuro-ophthalmologist Diagnosed a Brain Tumor

A first visit with a neurologist is likely to include taking a detailed medical history and a neurologic examination. It may include or be followed by imaging, nerve testing, or other tests or procedures.

A neurological exam is used to evaluate a variety of functions, including motor and sensory skills, hearing and speech, vision, coordination, balance, and mental status with the latter including mood and behavior. The neurologist may use a tuning fork, flashlight, reflex hammer, and a tool for examining the eyes during the exam.

During a neurological exam, the neurologist evaluates the patients muscle strength, sensory ability, coordination, and memory. To get a better sense of whats going on, neurologists may look at the way patients walk or button their shirts assess their posture, balance, and hearing and evaluate other areas of the body.

A neurological exam may also include:

Neurologists often order imaging studies to see detailed images of the brain and evaluate brain function. Types of imaging used in neurology include:

Additional testing may include:

What Is An Ophthalmologist

An ophthalmologist is a medical doctor or an osteopathic doctor who focuses on eye and vision care. Eye doctors are trained to carry out eye tests, diagnose and treat disease, recommend medications and perform eye surgery. They also compose prescriptions for spectacles and contact lenses.

Ophthalmologists generally complete four years of college, 4 years of medical school, one year of internship, and a minimum of 3 years of hospital-based residency in ophthalmology.

So , whereas the education of an eye doctor is similar to that of a general dental professional, the education and training of an eye doctor are more just like that of an oral surgeon.

Blood Supply To The Brain

Two sets of blood vessels supply blood and oxygen to the brain: the vertebral arteries and the carotid arteries.

The external carotid arteries extend up the sides of your neck, and are where you can feel your pulse when you touch the area with your fingertips. The internal carotid arteries branch into the skull and circulate blood to the front part of the brain.

The vertebral arteries follow the spinal column into the skull, where they join together at the brainstem and form the basilar artery, which supplies blood to the rear portions of the brain.

The circle of Willis, a loop of blood vessels near the bottom of the brain that connects major arteries, circulates blood from the front of the brain to the back and helps the arterial systems communicate with one another.

6 symptoms that should be evaluated by a neurological specialist

    Ive been getting painful headaches a lot lately, but they dont feel like regular tension headaches.

    Are these pins-and-needles sensations in my feet normal?

    Im so forgetful these days that its tough to work. I dont know if its stress-related brain fog or something else.

    Do I need to see a neurologist?

    Figuring out whether you need to see a specialist can feel like a tough call sometimes but many symptoms warrant it. We talked with Rush neurologist Tresa Zacharias, MD, about when it makes sense to see a neurologist.

    Neurologists specialize in treating and diagnosing disorders that affect the brain, spinal cord, and peripheral nervous system, including headaches, sleep disorders, multiple sclerosis, epilepsy, neuropathic pain, dementia, Parkinsons disease and stroke. While some neurologists specialize in one area, such as movement disorders or neuromuscular disease, others, like Zacharias, practice as general neurologists.

    If you need surgery or specialized care, your general neurologist can refer you to the specific specialist, but many conditions can effectively be managed by a general neurologist, Zacharias says. General neurologists offer a full range of medical therapies and nonsurgical procedures, from injections to lumbar punctures.

    She recommends being evaluated by a neurologist for these symptoms:

    What Happens During Brain Surgery

    Brain surgery is different for each person. Sometimes the surgical team needs to shave part of your head to operate, or they may just shave a tiny area to make an incision . Your head wont need to be shaved at all for most minimally invasive surgeries.

    Some procedures require general anesthesia, which means youre completely unconscious. But other procedures only need sedation, meaning youre partially asleep but can still respond to certain stimuli. During certain surgeries, you may even be awake during surgery. This is the case for some tumors, epilepsy or neurological conditions.

    During an awake craniotomy, you receive anesthetic on your head, so you dont feel pain from the incision. You also receive sedation to put you into a light sleep. But your surgeon and anesthesiologist wake you up during the surgery and ask you to perform tasks. You may need to speak, move a body part, look at objects or remember information. Prior to surgery, they may monitor your brain function using a functional MRI. Providers call this interoperative brain mapping. This process helps your surgeon avoid important areas of the brain during surgery.

    Brain surgery can take anywhere from two to nine hours or more, depending on the complexity of your surgery.

    Home Remedies For Brain Fog

    Some of the best remedies for brain fog listed in reputable websites are:

    1 Get some good sleep

    Hormones in your brain stay at the right levels when you get a good nights sleep. Remember that you cannot replace your night sleep if you choose to work during that part of the day. As an adult, you should sleep for at least seven hours per day.

    2 Include some exercise in your daily schedule

    Brain fog comes as a consequence of body fatigue. That is why engaging in a mild exercise could significantly improve your health, make your thyroid gland work better, and give you less stress and anxiety.

    3 Take care of your diet

    You are the sole responsible for your diet. Eating more healthy fats and proteins give you the amino acids needed for the right brain function. A good diet can fight against your depression, especially when you choose healthy foods.

    4 Reduce stress

    Adopt a lifestyle that promotes peacefulness to your relations with other people. Anxiety and stress can increase cortisol levels in your blood and worsen the cognitive fatigue symptoms and the memory loss you experience with brain fog.

    Neurologist Vs Neurosurgeon: In Summary

    The biggest difference between a neurologist and a neurosurgeon is a neurologist typically does not perform surgery, theyll nearly always diagnose a condition through a series of tests which the associated neurosurgeon will then utilize to best treat the condition through a surgical procedure. As for neurosurgeons, the main difference is theyre able to perform surgery on the brain, neck/back, and spinal cord due to possessing many, many years of studying, researching, and performing surgeries on the brain, neck/back, and spinal cord.

    Where Do Neurologists Work

    Neurologists see their patients in a clinic or surgery. Many work both in public and private hospitals. If they recommend surgery, they are likely to refer the patient to a neurosurgeon.

    Some neurologists work alongside other specialists and health professionals as part of a team, such as a hospital stroke team or critical care team.

    You Have Multiple Sclerosis

    is a lifelong disorder of the brain and spinal cord. Symptoms of MS can include changes in vision, weakness, numbness and sensations. Symptoms may come and go, but they progress over time. A neurologist will use results of an exam and imaging studies of your brain and spinal cord to make a diagnosis. Many medications can help control or slow down MS attacks. A neurologist will work with you to find the right treatment.

    Why Brain Surgery Is Done

    Brain surgery is done to correct physical abnormalities in the brain. These can be due to birth defect, disease, injury, or other problems.

    You may need brain surgery if you have any of the following conditions in or around the brain:

    • brain tumors
    • fluid building up in the brain

    Not all of these conditions require brain surgery, but many may be helped by it, especially if they pose a risk for more serious health problems. For example, a brain aneurysm doesnt require open brain surgery, but you may need open surgery if the vessel ruptures.

    There are several different types of brain surgery. The type used depends on the problem being treated.

    What Is A Neurologist

    what

    A neurologist is a medical doctor who diagnoses and treats diseases of the brain, spinal cord and central nervous system. Neurologists specialize in disorders such as cerebrovascular disease, or stroke, Parkinson’s disease, multiple sclerosis, Alzheimer’s disease, epilepsy, sleep disorders and chronic headache. Many neurologists specialize in one area, such as movement disorders or conditions related to dementia. They may specialize in treating children, in athletes who suffer sports injuries or in treating older adults.

    A neurology residency usually requires three years after the internship year. Some neurologists choose a longer residency in order to study a subspecialty. Neurologists do not perform surgery. If they determine surgery is necessary to the course of treatment, they will refer the patient to a neurosurgeon.
