What are causes of abnormal EEG results?

What are causes of abnormal EEG results?

EEGs are hard: An abnormal eeg can mean many things. Intermittent changes in eeg, like theta discharges or spikes, can be associated with epileptic seizures or other intermittent symptoms like migraine. Continuous changes, like slow background, can be an effect of drugs or internal disorders like liver or kidney disease. Changes in one spot of the head could mean damage like stroke or tumor. ...Read more

What kinds of patterns indicate disturbances in the conduction system on ecg?

What kinds of patterns indicate disturbances in the conduction system on ecg?

Conduction dis (CD) : Cd is reliably identified on ecg. Broadly speaking, it includes right bundle branch block (rbbb), left bbb, so-called left fascicular blocks, and non-specific conduction delays. Each has its own significance, with isolated fascicular blocks being the most benign. These patterns usually remain stable for years, even decades, but sometimes progress, so they do need follow up. ...Read more

What are the metabolic causes of a seizure?

Metabolic coz of sz: There are many. Electrolytes (sodium, calcium, potassium) being very low or high. Infections (non neurological infections too). Alcohol withdrawal. Alcohol toxicity. Medication side effects (wellbutrin). Low blood glucose. High blood glucose. Metabolic acidosis. Many of these causes can be treated. This is why people with a first time seizure undergo blood tests. ...Read more

What are the causes of myoclonic seizures?

What are the causes of myoclonic seizures?

Too many causes: Benign myoclonus can occur in children and adolescents. Jme is fairly common in young people - especially girls. Severe metabolic disorders will cause myoclonus, and anoxic brain damage can also cause myoclonus. A severe complex seizure disorder can develop in children and young adults - lennox gastaut - that may cause severe episodes of myoclonus and drop attacks. ...Read more

There are occasional high voltage sharp waves seen bilaterally. Is these the baseline for a neurologist give a diagnosis of ABNORMAL EEG?

EEG interpretation: An EEG done for very young patients is sometimes difficult to interpret. Abnormalities are common for patients less than 2 years old. It may be the pattern or size that are important. If the sharp waves are large enough though, these may be considered abnormal. ...Read more

What could cause an abnormal eeg?

Too many causes: The eeg is a measure of the electrical activity of the brain. The brain activity may run rough due to lack of sleep, medications, illness, drugs, brain damage, tumors, malformations, etc. Many findings on eeg are without explanation. Specific patterns may indicate a specific disease condition or be associated with a specific genetic disorder. Children can have strange but benign abnormalities. ...Read more

Causes of myoclonus?

It is a condition: Myoclunus just means jumping or jerking limbs. Usually it is the legs but can be any muscle. At night it may wake you up causing daytime fatigue. It can occur by itself or be part of a number of conditions where nerves in the head are not communicating with the nerves in the spine such as ms, head injury or pinched spinal nerves. Have a neurologist evaluate. ...Read more

Causes of borderline repolarization abnormality (ST dep & abnormal T)? Rest of ECG normal and echo normal.

Causes of borderline repolarization abnormality (ST dep & abnormal T)?  Rest of ECG normal and echo normal.

It is likely you are: referring to a computer interp. of your EKG. The computer program is slanted to indicate any potential abnormality no matter how insignificant. Ask a human with EKG experience (many FP and IM MDs do not possess any skills in reading EKGs they just read the English) to interpret the EKG for you. Odds are it is completely normal for you. You can attach it to an inbox consult with me if you want. ...Read more

Can lamictal cause abnormal EEG results?

Yes: Although Lamictal is used to treat epilepsy, a condition characterized often by abnormal eeg, it does affect the brain's electrical activity. As such it certainly does have the potential to change the eeg, just as does any other anti-epileptic drug/. ...Read more

I received a diagnosis of "Sinus Rhythm, T Wave Abnormality in anterior leads, borderline abnormal for age (29) and gender (F). Abnormal ECG. Worried?

Cardiologist: These T wave abnormalities are nonspecific and it's important to compare them to any prior EKG if one is available. If none are available the findings may not necessarily be due to any cardiac pathology and may even be a normal variant in a young woman. A cardiologist is best qualified to evaluate and examine you and recommend further testing like an echocardiogram if deemed advisable. ...Read more
