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.
The McCarthy Scales of Children's Abilities was intended to measure children from ages 2 to 8. The scale is very sound, and if there was more validity data, it could have very well obtained the same status as the Wechsler Intelligence Scale for Children. In fact, the Wechsler scale actually overlaps the McCarthy's age range.
The hippocampus is located in the medial temporal lobe (subcortical), and is an infolding of the medial temporal cortex. [1] The hippocampus plays an important role in the transfer of information from short-term memory to long-term memory during encoding and retrieval stages. These stages do not need to occur successively, but are, as studies ...
Normal aging is associated with a gradual decline in some types of memory, including episodic memory and working memory (or short-term memory). Because the hippocampus is thought to play a central role in memory, there has been considerable interest in the possibility that age-related declines could be caused by hippocampal deterioration.
The fifth edition incorporated a new scoring system, which can provide a wide range of information such as four intelligence score composites, five factor indices, and ten subtest scores. Additional scoring information includes percentile ranks, age equivalents, and a change-sensitive score (Janzen, Obrzut, & Marusiak, 2003).
Any score that falls below the 93rd percentile is considered normal, scores between the 93–97th percentile are borderline clinical, and any score above the 97th percentile are in the clinical range. Norms take into account both age and gender; there are separate norms for girls and boys, and separate norms for ages 6–11 and ages 12–18.
The DDST-II was adapted for use in Sri Lankan Children after a study was conducted in 2011, standardizing values among 4,251 children between the ages of 0–80 months. [15] Other countries that have conducted studies in order to standardize the DDST to their populations include Singapore, [ 15 ] Georgia, [ 16 ] and Brazil [ 17 ] where it was ...
The hippocampal subfields are four subfields CA1, CA2, CA3, and CA4 that make up the structure of the hippocampus. Regions described in the hippocampus are the head, body, and tail, and other hippocampal subfields include the dentate gyrus , the presubiculum , and the subiculum .
