Myotonic dystrophy does not have attributed behavior problems per se. However, Childhood and adolescent forms of the disease can exhibit cognitive difficulties which can present in a number of different ways such as attention deficit type disorders which could be mislabeled as behavior problems. Your best source of information on Myotonic Dystrophy on the web is the Myotonic Dystrophy Foundation.
Myotonic dystrophy is diagnosed clinically in individuals that have a specific type of muscle weakness. This is confirmed with molecular genetics testing, where the DMPK is analyzed
Symptoms in the congenital form of myotonic dystrophy are evident at birth. Affected infants show muscle weakness, respiratory defects, and eventually, mental retardation
Myotonic dystrophy cannot be cured, and no treatment can delay its progression. As of the early 2000s there is no standardized treatment for these disorders because the precise reasons for muscle weakness are not yet fully understood.
People who have myotonic dystrophy have progressive muscle wasting and weakness beginning in their 20's or 30's. The muscle wasting and weakness develop in their lower legs, hands, neck and face.
Myotonic dystrophy is relatively rare, occurring approximately once in 8,000 people. There is also a more rare, severe congenital form that occurs with an incidence of about 1 in 100,000.
limitations resulting from myotonic dystrophy can be significant, involving muscle weakness and difficulty lifting items and performing certain routine daily tasks. There are many cases in which affected persons experience mental delays
Yes, myotonic dystrophy affects people in multiple ways and can often affect other systems of the body before the skeletal muscles therefore an EMG is no longer a reliable diagnostic tool.
affects heart muscle, causing arrhythmias and heart block, and the muscles of the digestive system, leading to motility disorders and constipation. Other body systems are affected as well: Myotonic dystrophy may cause cataracts
stated to be 1 in 8000 in the USA, a few places have a higher incidence rate
Coefficient of discharge of an ideal liquid can be defined as a ratio of actual discharge and theoretical discharge. where, Cofficient of discharge = Actual Discharge/ Theoretical discharge.
