Normal Brain Vs Adhd Brain
Merely technical: Looking directly at base of brain and pituitary requires slightly different cuts and angles, as the focus is directed to a small area of brain, but the software and pictures are handled in a similar fashion. In ms, we tend to use specialized approaches, such as flair or double inversion recovery to see the white matter spots better. Not needed for pituitary views, usually. ...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.
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
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 moreSee 1 more doctor answer
Pathology type: Brain tumor is a generic term that includes benign, low grade and malignant brain tumors. Brain cancer refers to the malignant category. When one speaks of a brain cancer, this may be a primary (originating from the brain tissue) or metastatic (originating from cancer outside of the brain). Treatment depends on the type of cancer. ...Read more
Sometimes: Damage to the hippocampus may show up on MRI, especially if it is the reason the MRI is done- so that the hippocampus is examined in detail. Keep in mind though that extensive damage is ordinarily needed to show up on the MRI, and small disruptions may not show up. So there can be a damage and a normal MRI, unfortunately. ...Read moreSee 1 more doctor answer

How does dopamine and serotonin (chemically) reduce fear/anxiety in de brain? prefrontal cortex or amygdala? Or which parts of brain is involved?
Neurotransmitters: Medicines like Zoloft/Lexapro are serotonin reuptake inhibitors. Wellbutrin (bupropion) inhibits the uptake of norepinephrine and dopamine. Whether it is anxiety, irritability, anger, short fuse, or depression; these medicines regulate neurotransmitters in the brain to improve symptoms of insomnia, guilty feelings, poor concentration, fatigue, appetite disturbance, and lack of drive/interests. ...Read more
A few: A brain attack or stroke maybe from lack of blood flow(ischemic) or a bleed(either clot/embolism or aneurysm) in the brain(intraparenchemal). Both results in death of brain tissue. Other sources of hemorrhage can be in the surrounding tissues such as subdural(around the brain) or subarachnoid(around brain or spinal cord). ...Read more
MRI more accurate: Neuroimaging techniques can add valuable information (MRI) shows characteristic patterns depending on severity of the injury and also timing of imaging. Degree of edema and brain swelling is better seen by MRI than by computer tomography, therefore CT scans are not widely used for early outcome prediction. ...Read moreSee 2 more doctor answers
Hard to say...: Dopamine (DA) is not measured in clinical labs. It's extremely rapidly metabolized along a variety of pathways. Further, DA levels in blood bear little resemblance to DA activity in the brain - even less to the small brain regions and synapses where DA signaling is concentrated. Though DA *might* be relevant, the symptoms you describe could have a very large number of non-DA causes. ...Read more
No such thing: The umbrella term "brain tumor" includes a great many types of tumors both malignant and benign. Each has its own statistics regarding age at diagnosis. The most common adult primary brain cancer is glioblastoma multiforme, and the mean age at diagnosis for this tumor is around 64. ...Read more

All of this also requires good neuroradiology, good neuropathology, good nursing care and supportive care of all types. Don't be shy about asking for second opinions. ...Read more

Brain circulaton-sz: Why poor circulation ? ischemia (from clogged vessels)? hypoplastic vessels ( born with small vessels? carotids? Did MRI show stroke? Do they have a fib? was the seizure due to stroke/ TIA ( rare)? has the doctor discussed aspirin 81 mg or plavix (clopidogrel) or plental or fish oil ( blood thinners so may cause bleeding) ? f/u and discuss w/neurology http://www.ncbi.nlm.nih.gov/pubmed/11286042 ...Read more
