In creutzfeldt jacob disease (cjd) and/or new variant cjd, is the classical/alternate complement pathway negatively affected in any way?

In creutzfeldt jacob disease (cjd) and/or new variant cjd, is the classical/alternate complement pathway negatively affected in any way?

No: There's no inflammatory response to the prions. Given that everything affects everything else in a petri dish (which is why everything supposedly causes and prevents cancer), i must advise you that this line of inquiry isn't going to lead to anything helpful. I'm glad you have an inquiring mind, thanks for asking. ...Read more

When cjd is such a rare disease, why would a doctor declare a cjd diagnosis without a biopsy? Father had seizures, false positive prion test, dementia

When cjd is such a rare disease, why would a doctor declare a cjd diagnosis without a biopsy? Father had seizures, false positive prion test, dementia

What is a diagnosis: There is a difference between a confirmed diagnosis and a clinical diagnosis. Sometimes a clinical diagnosis is made, without confirmation. For many illnesses, there is no confirmatory test. Most people determine CJD with spinal fluid testing, a biopsy, or autopsy. ...Read more

Hypnagogic hallucination related to epilepsy? Had regular micro- or macropsia, other visual distortions before sleep, ended up diagnosis with t.L.E at 20.

Hypnagogic hallucination related to epilepsy? Had regular  micro- or macropsia, other visual distortions before sleep, ended up diagnosis with t.L.E  at 20.

Other consdierations: Micropsia and macropsia can be a symptom of epilepsy or of migraine. Symptoms of seizures are usually stereotyped, if there are a variety of visual distortions less likely to be epilepsy. Speak to your neurologist. Consider a 24 hour ambulatory eeg that might capture the symptoms on the recording to make a specific diagnosis. ...Read more

What is a delta rhythm in electroencephalogram?

What is a delta rhythm in electroencephalogram?

Slow brain activity: Delta rhythm is 0-4 hz activity in the brain seen on eeg. It is normally seen in deep sleep or in patients with brain disease, either focal (tumor, stroke) or generalized (intoxication, dementia). ...Read more

Help please! is bipolar disorder recognizable in one's eeg?

Help please! is bipolar disorder recognizable in one's eeg?

Possibly, not surely: One small study has shown that bipolar patients -- even when not in a mood episode -- have decreased Alpha activity in their eeg's. http://www.ncbi.nlm.nih.gov/pmc/articles/pmc3253163/ they were also free of medications for at least 2 weeks for the study. The authors feel this may differentiate bipolar from schizophrenia eeg's. It doesn't seem diagnostically definitive on its own, though. ...Read more

Will not help: Your lesions might be due to head injury smoking, hypertension, or migraine but could also be RIS, an early sign of MS. PET WON't dfferentiate but spinal tap or repeat MRI both brain and neck in 6 months might be considered ...Read more

Can a mid temporal strike found in an EEG be something other than epilepsy?

Yes: If brain waves in that area slow it could indicate damage to that area. If eeg slowing improves it icould indicate some healing is occuring. ...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

Can following a bike's flashing led trigger seizures in strobe-sensitive epilepsy?

Absolutely!: Each person with epilepsy may or may not have triggering factors; whether the led will cause a seizure depends on the speed of the flash as well as the individual. If the flash frequency is really slow, it may not trigger a seizure. ...Read more

My child has:decreased REM sleep & frequent wakings, migrational abnormality in brain that causes seizures, & behavioral probs.Is all of this connected?

Yes, an underlying: Neurological impairment likely causes all symptoms. Seek evaluation by a developmental/behavioral pediatrician to search for a genetic or other medical cause. There are known syndromes with lack of rem sleep, the most common of which is down syndrome. Comparative genomic hybridization & a dna probe for fragile x are genetic tests used when there are no physical findings of a specific syndrome. ...Read more

2 tonic-clonics in under a year (normal EEG and MRI), depression, tremors in left hand, sleep apnea, mouth ulcers, freq. infection. What's wrong?

More info needed: Thanks for your question. I understand that this can be very scary, especially when you don't have a clear cut diagnosis. I would recommend getting a second opinion, preferably from a large academic center. Definitely something going on and we need to get some answers for you. ...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

My mother's brain MRI shows hyperintense focus in t2w1/flair images in cerebellar vermis.Impression: ischemic focus in the cerebellar vermis.Explain.

Look at entire study: T2 and flair signal can be evidence of an "ischemic focus, " otherwise a stroke. However, other things could be in the mix, such as a tumor or demyelinating process. The radiologist will have looked at the other sequences. Sometimes, however, it can be tough to tell. ...Read more
