Spinal muscular atrophy (SMA) is a genetic condition that results in weakness and wasting of muscles in infants. For diagnosing spinal muscular atrophy (SMA), certain tests are carried out to check if your child has this condition.
Magnetic resonance imaging (MRI) has led to the identification of widespread brain abnormalities in multiple sclerosis (MS) that extend far beyond the classic white matter lesion. These findings have generated the idea that MS should be understood as a disease of the whole brain, not just the ...
Why is it often so difficult to diagnose lung cancer? How is microarray technology used to detect cancer in the body? What information can be found using microarrays? After a concussion, the blood-brain barrier may be temporarily less effective. What does this impair in brain function? Why is...
We use a 6-view lung ultrasound qualitative assessment to diagnose the cause of respiratory failure by assessment of lung sliding, pleural abnormalities, lung profiles (A/B/C), pleural effusion, and consolidations with or without dynamic air bronchograms [4]. One should be careful not to ...
Blood tests and ultrasound may be used to screen for Down syndrome but chromosome analysis of the fetus is needed to diagnose the condition. People with Down syndrome age more quickly and may develop Alzheimer's disease as young as age 40. Sometimes people are diagnosed with mosaic Down ...
True or False? An EEG uses ultrasound to diagnose brain dysfunctions. Suppose a girl developed generalized seizures. A CT scan revealed a single brain lesion consistent with a tumor. Biopsy of the lesion showed a cysticercus. The p...
Tests used to diagnose cataracts include: Visual Acuity TestFor this test, you’ll look at an eye chart showing rows of capital letters (usually) that are large at the top of the chart and progressively smaller toward the bottom of the chart. Your doctor will ask you to read from various...
How Do You Diagnose Spinal Muscular Atrophy? Spinal muscular atrophy (SMA) is a genetic condition that results in weakness and wasting of muscles in infants. For diagnosing spinal muscular atrophy (SMA), certain tests are carried out to check if your child has this condition. Miscarriage Miscarri...
One of the main ways to diagnose multiple sclerosis is an MRI (magnetic resonance imaging) scan. Characteristic areas of demyelination will show up as lesions on an MRI scan. On the left is a brain MRI scan of a 35-year-old man with relapsing remitting multiple sclerosis that reveals multip...
Understanding the genetics of brain structure and mental health susceptibility can help us better prevent, diagnose and treat these conditions. The concept of the "human brain" first appeared inancient Greece around 335 BCE. The philosopher Aristotle described it as a radiator that prevented the hear...
