What autoimmune diseases would attack nerves, brain cells , neurons, and part of our brain, so we lose our emotions feelings, empathy, inhibitions, ?

Generic question: Several possible answers, including limbic encephalitis, some variations of viral encephalitis, (of which there are many), perhaps multiple sclerosis should be included, and can find in isolated vasculitides, and arteritis associated with collagen vascular and rheumatological disorders. But why does this come up, has your doctor diagnosed such a condition? ...Read more

Lupus number one: The commonest cause of autoimmune cerebritis is central nervous system lupus. It is treatable. Another cause is bechets syndrome and there is a very rare form that is idiopathic, meaning cause is unknown. But lupus remains the commonest. ...Read more

Can an autoimmune disease effect our nerves, brain cells , neurons, and part of our brain, so we lose our emotions feelings, empathy, inhibitions, ?

Possible: It all depends on the kind of autoimmune disease and place of involvement. For instance, lupus could cause cerebritis ie brain inflammation and even could go as far as causing coma. But lupus could be only localized to other places like causing kidney disease, lung diseases, skin disease, or arthritis. ...Read more

LBD Clinical only: Neurodegenerative, progressive d/o with  milder physical parkinsonism than parkinson's disease typically. (slowed movements, stiff/rigid muscles & posture, possibly resting tremor).

New MRI machines like 7 tesla use very powerful magnets.There's iron in blood so can these machines change composition &chemistry of iron in blood?

New MRI machines like 7 tesla use very powerful magnets.There's iron in blood so can these machines change composition &chemistry of iron in blood?

No: The iron is the blood is chemically bound to the hemoglobin and is not in a magnetically susceptible state. Magnetic fields will not produce chemical changes but are used to orient the molecules in a uniform manner as part of the imaging process. ...Read more

Neurology/ radiology.What is brain rot?  Answers welcome in simple terms.Is it organic or disease?Is it neurovascular? Neurodegeneration? Toxicology?

Atrophy: Brain rot is a crude description of atrophy of the brain seen on ct or MRI scans. One can make educated guesses, based on the patient's history or exam, what the underlying problem might be. Age-related, alcohol, vascular or degenerative disease, are some potential causes. A detailed evaluation by your physician can help make the diagnosis. ...Read more

My mris generate vastly different interpretations. Some see tumors, lesions, hyperintensities. Others see nothing. Lesions are diagnosed as everything imaginable. No objective standard? What's up?

My mris generate vastly different interpretations.  Some see tumors, lesions, hyperintensities.  Others see nothing.  Lesions are diagnosed as everything imaginable. No objective standard?  What's up?

MRI: Not sure which MRI you are talking about. Is it of the brain, abdomen, chest? You should understand that MRI or ct scans are just "shadow" of your body organs. When we interpret we do come across atypical findings that baffle us. All radiological interpretations should be correlated with clinical findings to arrive at a reasonable diagnosis. ...Read more

What areas of brain does "mri brain stem w/o dye" image or cover?Is mra included in above and does it like mra image or look for cerebral aneurysm?

What areas of brain does "mri brain stem w/o dye"  image or cover?Is mra included in above and does it like mra image or look for cerebral aneurysm?

Whole brain stem: The MRI would look at your entire brainstem, shown in the picture. The brainstem is the lower part of your brain that controls breathing and heartrate. An mra (magentic resonance angiogram) is not the same, and would be ordered as a separate test with dye injection. An mra looks at blood vessels for aneurysyms, obstructions, or tears, while an MRI looks for tumors, demyelination, or strokes. ...Read more

Can clinical depression show up on a brain mri?

Can clinical depression show up on a brain mri?

Not likely: Traditional MRI cannot diagnosis depression, nor other "functional" problems, such as dementia, etc. Imaging such as MRI can only assess anatomy. There are functional MRI scanners which are in use, typical in research, frequently in dementia. Most applications of fmri are still experimental. ...Read more

Brain MRI findings. Tiny nonspecific periventricular and subcortical white matter. Possiblities mini strokes, vasculaties, ms. I shuffle my feet & drop?

Brain MRI findings. Tiny nonspecific periventricular and subcortical white matter. Possiblities mini strokes, vasculaties, ms. I shuffle my feet & drop?

Nonspecific finding: White matter changes that are nonspecific are sometimes over reported or under-reported on MRI studies. They may be misread and really suggest MS, they may be a finding with no clinical relevance. Usually it is the latter. It sounds like the brain MRI did not help that much. So you shuffle your feet and drop? What do you mean by drop? Do you have numbness? Why was the brain MRI done? ...Read more

Can Ct Scan damage brain , effect activity of brain?

Can Ct Scan damage brain , effect activity of brain?

No: The x ray radiation in a CT has no measurable or known effect on neural tissues. 1) dose is way too low and 2) nerves are relatively radioresistant since the cells don't reproduce very fast, if at all. There is a theoretical risk of cataracts and cancer years later, but this is incredibly small esp. for a single scan and controversial anyway. ...Read more

Headaches somewhat frequently. MRI brain normal. Go for MRA Brain or MR Spectroscopy of the brain? or MRI other parts? I get free MRI/MRA services.

Headaches somewhat frequently. MRI brain normal. Go for MRA Brain or MR Spectroscopy of the brain? or MRI other parts? I get free MRI/MRA services.

MRA for h/a: MRA would show even small aneurysms, so if you are concerned it may add some additional information about the vessels, including small or stenotic vessels and the carotids. Also consider thyroid, diabetes, musculoskeletal strain ,eyestrain from computer, allergies,sinusitis, food intolerances ( MSG is classic), mitral valve prolapse,hydrocephalus should have been seen on MRI,and migraines. ...Read more

I experience sudden loss of depth perceptin and my vision seems flat. 2 normal brain MRIs w/o contrast. Where else should we look?

See eye MD: Loss of depth perception is uncommon. It can be due to eye or brain factors. It seems the brain factors have been eliminated. Now you should focus your attention on eye factors, like alignment issues. For this, you should see an ophthalmologist. ...Read more
