  • Acanthocytosis-neurologic disorder

    Neuroacanthocytosis is a general term for a group of rare progressive disorders characterized by the association of misshapen, spiny red blood cells (acanthocytosis) and neurological abnormalities, especially movement disorders. Chorea, which is characterized by rapid, involuntary, purposeless movements, especially of the face, feet and hands, is the most common movement disorder associated with neuroacanthocytosis. Additional symptoms often d  Read More

  • Arachnoid cysts

    Arachnoid cysts are fluid-filled sacs that occur on the arachnoid membrane that covers the brain (intracranial) and the spinal cord (spinal). There are three membranes covering these parts of the central nervous system: the dura mater, arachnoid, and pia mater. Arachnoid cysts appear on the arachnoid membrane, and they may also expand into the space between the pia mater and arachnoid membranes (subarachnoid space). The most common locations f  Read More

  • Batten-mayou syndrome

    Batten-mayou syndrome is an inherited metabolic disorder. It is passed down through families, thereby triggering a genetic mutation in an individual. The batten-mayou syndrome is evident to affect the cell’s competency to break down cellular waste, thereby, eliminating it from the body. When the body is unable to get rid of the sugars, lipids and proteins, they start accumulating, in turn, affecting the nervous system an  Read More

Such accumulation can cause a variety of symptoms including letharg  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

    A high level of glycine in the body leads to a condition called nonketotic hyperglycinemia that primarily affects the nervous system. The disease onset occurs a few months after birth and has two forms: attenuated and severe. Early signs and symptoms are lethargy (which worsens over time and can lead to coma), life-threatening breathing difficulties, and weak muscle tone. The children who survive the early symptoms such as fee  Read More

  • Purpura, thrombotic thrombocytopenic

    Thrombotic thrombocytopenic purpura is a rare condition that leads to blood clots to build small blood vessels across the course of the body. Clots like these can result in severe medical issues if they end up blocking blood vessels and restrict the flow of blood to organs like the brain, kidneys and the heart. A protein of ADAMTS13 enzyme in the blood plays a role in blood clotting. An inadequacy in the ADAMTS13  Read More

  • Succinic semialdehyde dehydrogenase defi...

    Succinic semialdehyde dehydrogenase (SSADH) deficiency is a rare inborn error of metabolism that is inherited as an autosomal recessive trait. In individuals with the disorder, deficient activity of the SSADH enzyme disrupts the metabolism of gamma-aminobutyric acid (GABA). GABA is a natural chemical known as a "neurotransmitter" that serves to inhibit the electrical activities of nerve cells (inhibitory neurotransmitter). SSADH deficiency lea  Read More
