Recent studies have shown that mutations in phosphoinositide 3-kinase (PI3K) and AKT (also known as protein kinase B) pathway have been identified in MCAP and MPPH. This pathway has proven to be an integral part of brain growth and development and is an area of interest to many researchers who study the cause of megalencephaly.
This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e.g., Aicardi syndrome). There is disagreement over the definitions and criteria used to delineate various disorders and whether some of these conditions should be classified as ...
Many people with abnormally large heads or large skulls are healthy, but macrocephaly may be pathological. Pathologic macrocephaly may be due to megalencephaly (enlarged brain), hydrocephalus (abnormally increased cerebrospinal fluid), cranial hyperostosis (bone overgrowth), and other conditions. Pathologic macrocephaly is called "syndromic ...
For example, cerebrovascular disease involves brain injury due to problems with the blood vessels (cardiovascular system) supplying the brain; autoimmune disorders involve damage caused by the body's own immune system; lysosomal storage diseases such as Niemann–Pick disease can lead to neurological deterioration.
Another group of brain areas, the limbic system, may lead to feelings of fatigue, while an even deeper structure is likely responsible for the gastrointestinal symptoms. ... About 80% of people ...
Nervous system diseases, also known as nervous system or neurological disorders, refers to a small class of medical conditions affecting the nervous system.This category encompasses over 600 different conditions, including genetic disorders, infections, cancer, seizure disorders (such as epilepsy), conditions with a cardiovascular origin (such as stroke), congenital and developmental disorders ...
CMV is really common—more than half of adults have been infected with it by age 40, according to the Centers for Disease Control and Prevention (CDC). Most people with CMV show no symptoms, but ...
Some patients may have asymmetry of the brain, with one side being noticeably larger than the other. [ citation needed ] One interesting phenomenon that seems very common in this syndrome is the tendency for disproportionate brain growth in the first few years of life, with crossing of percentiles on the head circumference growth charts.
