With accurate diagnosis, most types of congenital myasthenia can be improved or at least stabilized by the use of drug therapy. More severe forms of the disease may weaken respiratory muscles and result in a reduced lifespan.
Symptoms usually progress to maximum severity within 3 years. With treatment, the outlook for most patients with MG is bright: significant improvement of muscle weakness and nearly normal lives.
The severity of symptoms, responsiveness to medication, and ultimate prognosis varies widely among congenital myasthenia patients.
There are no treatments available to cure congenital myasthenia. A number of medications may improve symptoms in children with congenital myasthenia.
Most cases of congenital myasthenia are inherited in a recessive fashion, meaning that a baby has to receive a defective gene from each parent to actually manifest the condition.
Accurate diagnosis of congenital myasthenia requires specialized testing. These include testing specific nerves to determine if the nerves fatigue more quickly than is normal
Most cases of congenital myasthenia are noticeable at or shortly after birth. In rare cases, symptoms don't present themselves until some time later in childhood or in early adult life.
Babies with congenital myasthenia are often described as "floppy," with weak muscle tone, droopy eyelids, excessive fatigue , compromised eye movements, facial weakness, feeding problems and delayed developmental milestones.
Congenital MG is an inherited condition caused by a genetic defect. The medical condition develops at or shortly after birth and causes generalized symptoms.
Neostigmine is preferred for treatment of myasthenia gravis. Pyridostigmine is longer acting than neostigmine.
A blepharectomy is surgical removal of the eyelid. Ocular myasthenia gravis is treated with immunosuppressive drugs and low dose alternate day treatment with prednisone.
The symptoms, which usually begin in infancy or toddlerhood, can include a poor sucking response, drooping eyelids (a condition called ptosis), eyes that appear to wander or float (ophthalmoplegia)
Cholinergic drugs are used for a variety of purposes, including the treatment of myasthenia gravis and during anesthesia.
Congenital methemoglobinemia is typically benign and should be observed. If methemoglobinemia symptoms occur the person should be taken to the hospital for treatment.
Study of CellCept and prednisone as immunotherapy in the treatment of MG. Another is the study of Etanercept to determine if it improves muscle strength in patients with MG.
A congenital defect that blocks a fetal airway such as congenital cystic adenomatoid malformation.
