How does a neurologist check for nerve damage?
Electromyography (EMG) is a form of electrodiagnostic testing that is used to study nerve and muscle function. It is commonly performed by a physiatrist or neurologist with special training for this procedure.
Can brain problems cause eye problems?
Yes, they can. Although eye problems typically stem from conditions unrelated to brain tumors—such as astigmatism, cataracts, detached retina and age-related degeneration—they can sometimes be caused by tumors within the brain. Brain tumors can lead to vision problems such as: Blurred vision.

What does the cerebral cortex do?
KEY POINTS. The cerebral cortex, the largest part of the brain, is the ultimate control and information-processing center in the brain. The cerebral cortex is responsible for many higher-order brain functions such as sensation, perception, memory, association, thought, and voluntary physical action.
Why does a neurologist look in your eyes?
A neurological exam tests the twelve cranial nerves by subtly dissociating their functions. Shining a small flashlight into one eye, for example, can distinguish between damage to CN II (the optic nerve) and damage to CN III (the oculomotor nerve).
What is the function of the cerebral cortex quizlet?
These functional areas of the cerebral cortex integrate information sensory, motor and other information from other brain areas; thus enabling higher order mental processes such as language, thinking, problem solving, etc. This is the primary cortex in the Occipital lobe.

Brain imaging can reveal unsuspected causes of your anxiety. Anxiety can be caused by many things, such as neurohormonal imbalances, post-traumatic stress syndrome, or head injuries. Brain scans can offer clues to potential root causes of your anxiety, which can help find the most effective treatment plan.
Can a neurologist diagnose depression?
Diagnosing Depression Because several medical conditions mimic depression symptoms, neurologists can help confirm a diagnosis of depression.

- Loss of feeling or tingling.
- Weakness or loss of muscle strength.
- Loss of sight or double vision.
- Memory loss.
- Impaired mental ability.

Can a brain scan show a chemical imbalance?
Current biological testing also cannot reliably verify a mental health condition. Doctors do not, therefore, diagnose mental health conditions by testing for chemical imbalances in the brain. Instead, they make a diagnosis based on a person’s symptoms and the findings of a physical examination.
What does a neurologist do for eyes?
Ophthalmologists treat eye and visual problems, and neurologists deal with issues of the brain. A neuro-ophthalmologist is in the middle, handling brain issues that affect vision. Neuro-ophthalmologists treat many vision disorders in addition to those associated with MS.
