Glossary for Muscle twitch

Medical terms related to Muscle twitch or mentioned in this section include:

  • Acid-Base Imbalance: A disruption to the normal acid-base equilibrium in the body. There are four main groups of disorder involving an acid-base imbalance: respiratory acidosis or alkalosis and metabolic acidosis or alkalosis. Obviously the severity of symptoms is determined by the degree of imbalance.
  • Adult progressive spinal muscular atrophy, Aran Duchenne type: A group of inherited motor neuron diseases involving progressive muscle weakness, wasting and paralysis due to degeneration of motor neurons in the spinal cord. Muscle weakness and wasting usually starts in the hands and may gradually spread to other muscle groups.
  • Aicardi syndrome: A rare genetic disorder where the structure connecting the two halves of the brain fails to develop which results in seizures and eye abnormalities .
  • Alkalosis: A condition that iscaused by the accumulation of base in the body.
  • Alzheimer disease 10: An inherited form of Alzheimer's. Type 10 is caused by a genetic defect on chromosome 10p13.
  • Alzheimer disease 12: An inherited form of Alzheimer's. Type 12 is caused by a genetic defect on chromosome 8p12-q22.
  • Alzheimer disease 13: An inherited form of Alzheimer's disease that is linked to a defect on chromosome 1q21. Alzheimer's disease is a progressive disorder involving degeneration of the brain. The disease mainly affects brain functions involving thinking, memory, personality and behaviour.
  • Alzheimer disease 14: An inherited form of Alzheimer's disease that is linked to a defect on chromosome 1q25. Alzheimer's disease is a progressive disorder involving degeneration of the brain. The disease mainly affects brain functions involving thinking, memory, personality and behaviour.

  • Alzheimer disease type 1: A degenerative brain disease characterized primarily by progressive dementia. Type 1 has an early onset (starts before the age of 65). It is caused by mutations in the APP gene which results in the production of a toxic protein (amyloid beta peptide) in the brain which collects into clumps (amyloid plaques) in the brain. These plaques cause damage to nerve cells in the brain.
