  • Fahr disease

    Familial idiopathic basal ganglia calcification (FIBGC) is a rare neurological disorder characterized by the presence of abnormal calcium deposits (calcifications) of unknown cause. Associated symptoms include progressive deterioration of cognitive abilities (dementia), loss of contact with reality (psychosis), mood swings and loss of acquired motor skills. As the condition progresses, paralysis may develop that is associated with increased mu  Read More

  • Idiopathic basal ganglia calcification

    Idiopathic basal ganglia calcification is a hereditary, genetic condition marked by abnormal calcium deposits in parts of the brain that regulate movement. Basal ganglia, cerebral, and cortical regions (parts of the brain) have calcium deposits that cause atrophy. Motor and mental problems result from the considerable neuron (brain cell) loss caused by this mineral deposit. There is a paucity of molecular and gene  Read More

  • Isaacs' syndrome

    Acquired neuromyotonia is an inflammatory disorder characterized by abnormal nerve impulses from the peripheral nerves that result in continuous muscle fiber activity. Affected individuals often experience progressive muscle stiffness and cramping especially in the hands and feet, increased sweating, and delayed muscle relaxation. Symptoms may persist even during sleep or under general anesthesia.  Read More

  • Isaacs-merten syndrome

    Acquired neuromyotonia is an inflammatory disorder characterized by abnormal nerve impulses from the peripheral nerves that result in continuous muscle fiber activity. Affected individuals often experience progressive muscle stiffness and cramping especially in the hands and feet, increased sweating, and delayed muscle relaxation. Symptoms may persist even during sleep or under general anesthesia.  Read More

  • Kok disease

    Hyperekplexia is a rare hereditary, neurological disorder that may affect infants as newborns (neonatal) or prior to birth (in utero). It may also affect children and adults. Individuals with this disorder have an excessive startle reaction (eye blinking or body spasms) to sudden unexpected noise, movement, or touch. Symptoms include extreme muscle tension (stiffness or hypertonia) that prevent voluntary movement and can cause the affected per  Read More

  • Nonketotic hyperglycinemia

    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

  • Quantal squander

    Acquired neuromyotonia is an inflammatory disorder characterized by abnormal nerve impulses from the peripheral nerves that result in continuous muscle fiber activity. Affected individuals often experience progressive muscle stiffness and cramping especially in the hands and feet, increased sweating, and delayed muscle relaxation. Symptoms may persist even during sleep or under general anesthesia.  Read More
