The severity of scleroderma varies from person to person. People with hereditary hyperekplexia who have epilepsy have the seizure disorder throughout their lives. Muscular rigidity often fluctuates (i.e., grows worse and then improves) and usually occurs along with the muscle spasms. Hereditary hyperekplexia is a condition in which affected infants have increased muscle tone (hypertonia) and an exaggerated startle reaction to unexpected stimuli, especially loud noises. [35] Patients with classic or partial SMS and GAD-65-positive antibody have shown improvement in stiffness and spasm symptoms with long-term benzodiazepine treatment. Motor cortex excitability was more enhanced in patients with anti-GAD antibodies and correlated with antibody levels in CSF. The exact prevalence of hereditary hyperekplexia is unknown.

The normal lifespan of a grown adult can be stated as 50 years (if symptoms start early). [6] These muscles repeatedly and involuntarily contract, causing them to grow and rigidify. Breaking through barriers to find a cure. It is caused by increased muscle activity due to decreased inhibition of the central nervous system (CNS) that . Lyme Disease News [24] The antibodies appear to interact with antigens in the brain neurons and the spinal cord synapses, causing a functional blockade of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA). B., Guarnaccia, J. SPS is a hereditary, congenital disorder that can occur in ten individuals from several generations of a family. Muscle stiffness in the trunk and limbs: This causes back stiffness or pain and a stiff-legged walk. [7] This leads to GABA impairment, which probably causes the stiffness and spasms that characterize SPS. [48][49], Hematopoietic stem cell transplantation (HSCT) with high intensity conditioning protocol has been performed in a few cases with severe anti-GAD positive SPS, resulting in clinical remission. "While were still learning about this rare condition, we now know this is whats been causing all of the spasms that Ive been having.
