Hippocampal sclerosis is the most common brain abnormality in those with temporal lobe epilepsy. [16] Hippocampal sclerosis may occur in children under 2 years of age with 1 instance seen as early as 6 months. [17] About 70% of those evaluated for temporal lobe epilepsy surgery have hippocampal sclerosis.
Anatomy and physiology is different in infants and children than adults and vary with age, which produces normal ranges for electrocardiograms. [26] Capillary refill is used across the lifespan as a cardiovascular assessment parameter because it is a non-invasive, quick test to help determine blood flow to the tissues.
In the UK, the Royal College of Physicians developed the National Early Warning Score (NEWS) in 2012 to replace local or regional scores. [16] [17] [18] The NEWS score is the largest national EWS effort to date and has been adopted by some international healthcare services. [1] A second version of the score was introduced in 2017.
This is due to the fact that dentate granule cells play a critical role in the function of the entorhinal-hippocampal circuitry in health and disease. Dentate granule cells are situated to regulate the flow of information into the hippocampus, a structure required for normal learning and memory. [24]
The hippocampus is considered the memory center for the brain and is responsible for storing, encoding, retrieving, and reconsolidating memories. [8] Studies indicate that people who have PTSD may have a "shrunken" hippocampus, some estimates indicate that there may be up to a decrease in a range of 5-26%. [10]
Scores for individuals in each age group are norm-referenced. The ASEBA has been translated in one hundred languages, and has a variety of multicultural applications. [ 2 ] Each report form in the ASEBA System has 113 items, but there is not a one-to-one correspondence between each individual item across the different report forms.

It has been proposed that the trisynaptic circuit is responsible for the generation of hippocampal theta waves. These waves are responsible for the synchronization of different brain regions, especially the limbic system. [9] In rats, theta waves range between 3–8 Hz and their amplitudes range from 50 to 100 μV.
