Question: Intermittant Focal Theta Slowing

 Jumbo - Sat Apr 11, 2009 3:18 pm

I had an EEG which reported intermittant focal theta slowing in mid to anterior left temporal region. Occasional spikes and sharp waves in same region. Accentuated by hyperventilation and drowsiness.

MRI showed scant gliosis in periventricular white matter.

Can anyone translate the above into plain language for me and explain what it could be?

I was referred due to a couple of incidents of vertigo and general feeling of not being 'right'.

Many thanks!

User avatar Hello --

The connection between focal theta slowing (especially when exacerbated by hyperventilation) can often be indicative of a relatively innocent but potentially bothersome lesion which may be causing some minor focal seizure activity manifested as vertigo or a vaguely detached or depersonalized feeling. This may be what you're attempting to describe by "not being 'right'." It is subject to interpretation by the neurologist of record, who may or may not have been the one who wrote the report. This could be something as simple as "absence seizures" (petit mal epilepsy) or even less well-defined focal activity which may require some medical therapy (anti-seizure medication) or may simply call for followups and observation for potential progression to a more intrusive sort of symtpom. Your neurologist will best be able to interpret the findings but they sound fairly ordinary in the reading at least, and probably relatively minor.

Hope this is helpful. Good luck to you and please follow up with us here as needed.
