Step-by-step explanation
Neuronal migration disorder are a group of birth defects caused by the abnormal migration og neurons inthe developing brain and nervous system. In developing brain, neurons must migrate from the areas where they are born to the areas where they will settle into their proper neural circuits. When these signals are absent or incorrect, neurons do not end up where they belong. This can result in structurally abnormal or missing areas of the brain in the cerebral hemisphere. The structural abnormalities found in NMDs include schizenpaly, porencephaly, lissencephaly, microgyria, porencephaly.
Neurodevelopmental disorders including ASD(Autism), Schizoprenia, this is due to the prepondence of penetrant mutation associatedwith synaptic structure and function.
Cerebral palsy is a group disorder that affect a person's abilty to move and maintain balance and posture. It is caused by abnormal brain development or damage to the developing brain that affects a person's ability to control muscles.
