Kearns-Sayre patients are consistently found to have cerebral folate deficiency, a syndrome in which 5-MTHF levels are decreased in the cerebrospinal fluid despite being normal in serum. [5] Treatment with folinic acid can in some cases alleviate the associated symptoms and partially correct associated brain abnormalities, especially if started ...
Mitochondrial encephalomyopathies, such as Kearns–Sayre syndrome, which interfere with the basic functions of neurons; Posterior cortical atrophy: in the most posterior area of the brain lies the visual cortex, the area of the brain where visual information is received and processed.
An example is commissural disconnect in adults which usually results from surgical intervention, tumor, or interruption of the blood supply to the corpus callosum or the immediately adjacent structures. Callosal disconnection syndrome is characterized by left ideomotor apraxia and left-hand agraphia and/or tactile anomia, and is relatively rare.
Split-brain or callosal syndrome is a type of disconnection syndrome when the corpus callosum connecting the two hemispheres of the brain is severed to some degree. It is an association of symptoms produced by disruption of, or interference with, the connection between the hemispheres of the brain.
Agenesis of the corpus callosum (ACC) is a rare congenital disorder that is one of the most common brain malformations observed in human beings, [30] in which the corpus callosum is partially or completely absent. ACC is usually diagnosed within the first two years of life, and may manifest as a severe syndrome in infancy or childhood, as a ...
Chronic progressive external ophthalmoplegia (CPEO) is a type of eye disorder characterized by slowly progressive inability to move the eyes and eyebrows. [1] It is often the only feature of mitochondrial disease, in which case the term CPEO may be given as the diagnosis.
Over time, being in a constant inflammatory state can start to damage healthy cells and increase your risk for certain diseases, including autoimmune diseases, type 2 diabetes, dementia, obesity ...
Hypoplasia of the corpus callosum, often in conjunction with other major malformations, is significantly associated with poor and delayed developmental outcome. [4] ONH is often referred to as septo-optic dysplasia, a term that refers to agenesis of the septum pellucidum. It is now clear that the absence of the septum pellucidum does not ...
