Will it show up if I smoke on eeg?

Will it show up if I smoke on eeg?

EEG: Measures the electrical activity of the brain. Various drugs when taken in larger does can cause changes in a patient's eeg. Usual doses of nicotine will likely not cause eeg changes.

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

I am having a 5 day EEG test and if I smoke cannabis during it will they notice some changes that I should be worried about?

I am having a 5 day EEG test and if I smoke cannabis during it will they notice some changes that I should be worried about?

Cannabis Dependence: EEG is done for Diagnosis of seizure disorders, head injury, memory problems or sleep disorders. Physicians evaluate EEG findings in the context of complete history, Neurological examination and Mental Status. Ask -if use of Cannabis has affected your concentration, thinking, emotions, memory and judgement; fallen down, or had seizures, then have EEG Follow treatment with Neurologist; NA Meetings

Can add show up on a eeg?

Can add show up on a eeg?

NO: Add or adhd is neurobehavioral and biochemical disorder and diagnosed clinically. Eeg will not show any features of add. However, egg can rule out conditions such as absence seizures that can present as staring spells. Egg is not needed for diagnosis of add.

Does the EEG show changes if you're thinking different things during the test?

Does the EEG show changes if you're thinking different things during the test?

No: Eeg is a measurement of surface electrical activity of the brain. This will not show changes with different thoughts. It will show changes with seizures, sleeping or other major electrical events occurring within the brain.

Does Wilsons Disease show on an EEG?

Does Wilsons Disease show on an EEG?

Wilsons disease: Can cause hepatic encephalopathy which in turn can produce slow anterior triphasic waves on an EEG in the absence of liver failure it would not likely produce changes on an EEG. There are labs tests and eye findings that may be helpful in arriving at a diagnosis.

Would an EEG show inflammation of the brain?

Would an EEG show inflammation of the brain?

EEG: Eeg can show overall slowing of the brain waves in certain type of inflammations or infections especially if the patient had clinical encephalopathy i.E if the person is drowsy, sleepy or comatose.

Can eegs show the different sleep stages?

Can eegs show the different sleep stages?

Yes.: Yes, the stages of sleep are identified through eeg. Stages w (wakefulness), n1, n2, n3, and r (rem). You sleep study will be able to measure the time and % you spend in each of these states. Sleep patterns and architecture change for individuals throughout life. They are dynamic and distinct.

Can an EEG show an abnormality that is not epileptic in nature?

Quite frequently: The eeg is a crude measure of brain electrical activity. It often also contains events of eye movements, swallowing, breathing, movement, as well as outside electrical events including lightning. It is very important for the neurologist evaluating the eeg to be knowledgable about all the possible artifacts and variations. Eegs on children are very often full of such non-epileptic events.

Can an EEG show that there is a vestibular dysfunction or is the diagnosis obtained from other more reliable testing?

ENG or VNG: Ear nose and throat doctors, neurologists, and audiologists can do an ENG or VNG for this. An EEG or brain wave test may help but is usually normal.

Would an EEG show MS? What about encephalopathy?

Not at all: EEG is not of value in confirming diagnosis of MS. If encephalopathy, abnormal EEG patterns may be present, but will not reveal etiology. Other tests needed to confirm either condition.

Would CNS vasculitis show up on eeg?

Would CNS vasculitis show up on eeg?

Need clarification: CNS vasculitis is an inflammatory condition affecting the brain and is diagnosed by tests of structure (mri, arteriogram...) and less of function (eeg, evoked potentials. However, there are frequent eeg abnormalities depending upon the presentation of the vasculitis such as whether the patient has had a seizure. I hope this helps. Take care.

Does EEG on brain show if I had a stroke?

Does EEG on brain show if I had a stroke?

Depends: A large stroke that involves the outer layer of the brain (cortex) can cause enough depression of the electrical activity that this will be detectable on an eeg. Due to the somewhat limited space resolution (think that there are only about 10 electrodes per head side or so) a very small amount of no functioning brain tissue (stroke) is difficult to detect. An eeg is not the test of choice for this.

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.

Does an EEG show marijuana use?

Does an EEG show marijuana use?

No: If your question is about specific, unequivocal signs of marijuana use, the answer is clearly no. I am pretty sure, however, that during an acute intoxication with marijuana, eeg may likely differ from a person s normal/baseline waves pattern. Stay clean.

Would a 24hr ambulatory EEG show any signs of sleep apnea?

Would a 24hr ambulatory EEG show any signs of sleep apnea?

Inefficient: The ambulatory eeg is intended to uncover occult seizure activity, and an overnight sleep study is geared to diagnose apnea.

Does an EEG show seizures or just the brain waves?

Does an EEG show seizures or just the brain waves?

EEG: Eeg shows brain activity in wave form which helps to diagnose certain conditions such as seizures, metabolic encephalopathies, encephalitis etc.

Do all seizures show up on eegs and aeegs. Do normal mris and eegs rule out seizures. If so what could the "seizures" be?

Seizures: Not all seizures will show up on eeg. An MRI will only show a structural problem or other physical problem in the brain (although it may be the source of the seizure).

I just found that I have hypothyroidism what does it effect and could it be causing my seizures and does those seizures show up on eegs

I just found that I have hypothyroidism what does it effect and could it be causing my seizures and does those seizures show up on eegs

Probably not: Hypothyroidism affects every organ and process in your body, so I can say it hasn't affected your seizures, but that's unlikely. It may affect your body's metabolism of your meds however. Luckily, proper replacement with brand name T4 can bring your thyroid level back to normal, and then it will be just like you never had a problem to begin with.
