The role of Project 1 in this Program Project is: 1. To | |
preserve tissue from 72 brains, according to a | |
standardized protocol for neuropathological studies | |
(project # 1) and for morphometric studies (project# 2); | |
2. To implement clinical and neuropathological exclusion | |
criteria to reduce the risk of distortion of results and | |
conclusions by comorbidity, pre-, peri, and postmortem | |
tissue changes, (3) to define type, topography and | |
severity of qualitative developmental alterations in | |
idiopathic autism and autism associated with dup15, and | |
(4) to examine correlations between focal developmental | |
changes and epilepsy and sudden death. Severe | |
microcephaly, with brain weight reduced by 300 g is one | |
of the most significant signs of global encephalopathy | |
increasing the risk of epilepsy in dup 15 cohort. 2.8 | |
times more frequent developmental alterations, especially | |
common in the hippocampal formation of autistic subjects | |
with dup15, and presence up to 11 different types of | |
developmental alterations are the major contributors to | |
early onset of epilepsy and high risk of SUDEP. Reduced | |
volume of neurons in a majority of subcortical structures | |
and some cortical regions in the brain of autistic | |
children with known and unknown etiology indicates that | |
altered trajectory of neuron growth and desynchronization | |
of neuronal development is a common denominator for | |
autism regardless of etiology and is linked to autistic | |
phenotype and intellectual deficits. However, different | |
pattern of developmental deficits neuron volume in | |
idiopathic autism (most severe volume deficit in 4-8 | |
years old subjects and correction of neuron size in late | |
childhood) than in autism associated with dup (15) | |
(permanent neuron volume deficit regardless of age) | |
indicates that etiology defines the trajectory of neuron | |
and brain development. | |
