Does an abnormal EEG confirm epilepsy in you?

Does an abnormal EEG confirm epilepsy in you?

Yes and no: The eeg is a tool to be used by a trained neurologist to help diagnose epilepsy. The eeg alone is of little value. The history and examination are the important elements. Eeg recorded during a seizure can be very helpful but difficult to obtain. Baseline eeg can show abnormal activity, especially in children, even though the patient has never had a seizure. It is valuable in the right hands. ...Read more

Eeg (Definition)

An electroencephaolgram (eeg) is a test that uses wires on the scalp to measure electrical activity produced by the brain. It is used to assess cerebral activity, and can be very helpful in the diagnosis and treatment of seizures as well ...Read more

What does parietal periventricular signal alteration on a brain MRI mean?

What does parietal periventricular signal alteration on a brain MRI mean?

A change: There is a change in the signal in the tissue that surrounds the brain ventricles. That is not very specific. For example as we get older than say 20? then this finding may become more prominent. It also depends on why you had the study done in the first place. It may reflect why you are having symptoms. To put it all together talk to your doctor. ...Read more

Mri reading need interpretation , focal swelling with heterogenous abnormal signal in the spinal coed atc5-c6 level suggesting neoplasm has improved?

Mri reading need interpretation ,  focal swelling with heterogenous abnormal signal in the spinal coed atc5-c6 level suggesting neoplasm has improved?

Need to discuss with: As stated, this sounds as if you had a type of previous "neoplasm" and the test is showing an improvement in the swelling around certain areas of your neck at c5-6. Possibly the radiologist did not know your history of previous neck surgery in the area. I recommend you have the ordering dr discuss your hx and the findings with the radiologist and then discuss in detail with you. Best wishes. ...Read more

What test will show brainstem activity other than eeg.

What test will show brainstem activity other than eeg.

None: No test shows activity directly. Some tests can be used to assess certain functions of the brainstem. This includes vestibular testing, some forms of autonomic testing, eye movement testing, among others. ...Read more

Had polysomnography.  Please explain: increase in phasic motor activity w/o stereotypical behaviors seen during REM sleep.  ?

Jump around: in sleep. This needs to be interpreted in the context of all the other brain findings of the sleep study. by itself it isn't all that important and doesn't indicate much except a potential problem for interrupted sleep. especially for the person next to you. ...Read more

What brain problems does an EEG detect?

What brain problems does an EEG detect?

Many: Mostly eeg is used to diagnose epilepsy, it is also used to diagnose to diagnose brain death. It can be found abnormal in many focal or diffuse diseases, herpes simplex j. C disease. By eeg alone specific problems are not always diagnosable. ...Read more

Clarification: You have multiple issues, and most would strongly implicate MS. But if an MRI of both brain and spinal cord is normal, you do NOT have MS. However, several other possibilities exist, and you need to clarify your diagnosis. May help to obtain another opinion. ...Read more

Can REM behavior disorder show up on an EEG test at a hospital ?

Possibly: If the eeg is focused on recording different sleep phases and done long enough it may pick up the rem activity, but usually, short studies over an hour or two may miss these events. Perhaps best to do a sleep overnite study, which more likely will demonstrate ...Read more

Saw neuro after visual disturbance, probable migraine. MRI to r/o mass, found 3mm hyperintensity ant. parietal subcortical. Ref'd to MS specialist?

Saw neuro after visual disturbance, probable migraine. MRI to r/o mass, found 3mm hyperintensity ant. parietal subcortical. Ref'd to MS specialist?

Depends: There are many lesions that appear on imaging as non-specific and can be seen in many lesions. There are exact criteria that are present which makes MRI useful in the diagnosis, discussing with another specialist might discern or eliminate this diagnosis. The finding on MRI is more consistent with migraine. ...Read more

Mri: sm. Amt of subcortical/periventricular signal. Meaning?  Mild encephalomalacia. Meaning? history sle, ra, meningioma sx. Age 59. Mri due to dizzyness.

Non-specific changes: I do not see anything serious in this report. Slight changes of this or that are commonly reported by radiologists. But it is your treating doctors job to put these in proper perspective. All i can see it is that these changes do not point me in any direction except that it can serve as a base line for future comparisons to see if there is any progressive changes in future. ...Read more

2 doctors agreed:
Can an EEG (electroencephalogram) detect brain tumors?

No: Eeg can show presence of seizure brain wave activity.These seizure brain activity can be caused by different conditions such as metabolic abnormality, lack of blood supply to brain cells, medication, epilepsy, brain tumor related, etc. It analyzes the brain "function" not the anatomy thus it can't detect brain tumor specifically. Mri needs to be done to detect brain tumors. Discuss with your md. ...Read more

Okay, but...: Your semen analysis is okay, but its parameter is just a rough indicator of fertility since some 50% of its causes lie in female factors; 30%, in male's; 20% in both'female and male factors.

It is hard...: ...to comment on an MRI without knowing clinical details. The radiologist should have put his/her impression in the report and that may provide additional information. However, the physician who ordered the MRI would be the best person from whom to seek an explanation. Wish you the best. ...Read more
