An apple and the aged brain

-
An apple can be compared to a human brain. If you zoom the apple, very carefully, you will observe that the apple is getting near to the expiry date (older & rotten). Similarly, you can compare with an aged brain (beyond a threshold +65), where you would see shrinkage in the brain with an intrinsic curvature (As you see in the apple). Lol. Don't think, I am funny, but that's the fact. Be happy!! Weekend vibes. ☕☕☕

Early developmental changes in the brain

-
Abstract Brain undergoes most of the dynamic change in utero and the developmental changes continue over the first two postnatal years of life. Early phase of life is very crucial as neurodevelopmental disorder such as Autism, ADHD are likely to be noticeable during the first years of life. Better understanding of normal brain pattern is necessary for identifying abnormal developmental pattern. In the present case, a typical neurologically normal infant was scanned using 18 F-FDG PET during its sixth and ninth months. At sixth month, infant showed maximum 18 F-FDG uptake in subcortical structures including basal ganglia and thalamus. After three months follow-up from the baseline the infant showed increased 18 F-FDG uptake globally. Basal ganglia, thalamus and visual cortices showed maximum 18 F-FDG uptake compared to other regions of the brain, while medial temporal cortex and cerebellum showed the minimum 18 F-FDG uptake. The present case demonstrates the brain 18 F-FDG uptake in a...

Understanding Autism Spectrum Disorder through molecular imaging

-
Image
[ 18 F] 2-fluoro-2-deoxy-D-glucose positron emission tomography-computed tomography scan was performed on 45 children with autism to study the baseline pattern and age-related developmental changes in the brain metabolism. Median standardized uptake values (SUVs) were compared with published healthy control data. Results showed that, in contrary to control data, the median SUVs in children with autism decrease linearly with increase in age. As compared to controls, autism children below 5 years showed greater metabolism and older children showed lower metabolism. In autism group, comparison of absolute SUVs within different regions of the brain revealed relatively lower metabolism in amygdala, hippocampus, parahippocampal gyrus, caudate nucleus, cerebellum, mesial temporal lobe, thalamus, superior and middle temporal pole, and higher metabolic uptake in calcarine fssure and Heschl’s gyrus. These results help in understanding the baseline metabolism and developmental changes of brain...
