- Agenesis of commissura magna cerebri
Agenesis of corpus callosum (ACC) is a rare disorder that is present at birth (congenital). It is characterized by a partial or complete absence (agenesis) of an area of the brain that connects the two cerebral hemispheres. This part of the brain is normally composed of transverse fibers. The cause of agenesis of corpus callosum is usually not known, but it can be inherited as either an autosomal recessive trait or an X-linked dominant trait. Read More
- Dancing eyes-dancing feet
Opsoclonus-myoclonus syndrome (OMS) is a paraneoplastic neurological disorder. It is characterized by associated ocular, motor, behavioral, sleep, and language disturbances. The onset is usually abrupt, often severe, and can become chronic. Read More
- Hallervorden-spatz syndrome (hss)
Pantothenate kinase-associated neurodegeneration (PKAN), formerly called Hallervorden-Spatz syndrome, is a rare, inherited neurological movement disorder characterized by the progressive degeneration of the nervous system (neurodegenerative disorder). PKAN is the most common type of neurodegeneration with brain iron accumulation (NBIA), a group of clinical disorders marked by progressive abnormal involuntary movements, alterations in muscle to Read More
- Kinsbourne syndrome
Opsoclonus-myoclonus syndrome (OMS) is a paraneoplastic neurological disorder. It is characterized by associated ocular, motor, behavioral, sleep, and language disturbances. The onset is usually abrupt, often severe, and can become chronic. Read More
- Moya-moya disease
Moyamoya syndrome is a progressive disorder that affects the blood vessels in the brain (cerebrovascular). It is characterized by the narrowing (stenosis) and/or closing (occlusion) of the carotid artery inside the skull, the major artery that delivers blood to the brain. At the same time, tiny blood vessels at the base of the brain open up in an apparent attempt to supply blood to the brain distal to the blockage. These tiny vessels are the " Read More
- Moyamoya syndrome
Moyamoya syndrome is defined as a progressive condition that disturbs the blood vessels in the brain. One of its earliest signs of evidence is stenosis or occlusion of the carotid artery present in the skull. Simultaneously, this blockage of blood impels the minute blood vessels at the base of the brain open up. It is said to be an attempt to improve the blood supply. The tiny blood vessels --named moyamoya-- give the disease Read More
- Mucopolysaccharidosis type iii
Mucopolysaccharidosis type III, also known as Sanfilippo syndrome, is an inborn error in the metabolism of mucopolysaccharides. It reflects in deficiency or little activity of enzymes required for the catabolism of mucopolysaccharides leading to its accumulation. The disease presents with neurological manifestations such as autism, intellectual disability, behavioral problems, sleep disturbances, developmental regression, and Read More
- Neill-dingwall syndrome
Neill-Dingwall syndrome, also known as Cockayne syndrome, is a disorder characterized by a variety of clinical features, including cachectic dwarfism, severe neurological manifestations including microcephaly and cognitive deficits, pigmentary retinopathy, cataracts, sensorineural deafness, and ambulatory and feeding difficulties. It is an autosomal recessive genetic disorder, which leads to death by the age of 12 years on ave Read More
- Pineal cysts, symptomatic
Pineal cysts, Symptomatic are commonly found in individuals in their 40s. Cysts refer to the closed structures formed by one or more layers of tissues filled with fluid. Pineal cysts are made of the inner layer of gliotic cells, a middle layer of pineal parenchyma, and an outer layer of connective tissue. The fluid is proteinaceous. Cysts are either typical (unilocular) or atypical (multilocular with septations). Usually, the Read More
- Sulfatide lipidosis
Metachromatic leukodystrophy, the most common form of leukodystrophy, is a rare inherited neurometabolic disorder affecting the white matter of the brain (leukoencephalopathy). It is characterized by the accumulation of a fatty substance known as sulfatide (a sphingolipid) in the brain and other areas of the body (i.e., liver, gall bladder, kidneys, and/or spleen). The fatty protective covering on the nerve fibers (myelin) is lost from areas o Read More
