whats duchenne muscular dystrophy |
-genetic condition that affects muscles and causes weakness. progressive |
|
epidemiology of DMD |
- starts in early childhood esp. around 3YO -mainly affects boys only |
|
eatiology/pathopysiology of DMD |
genetic defect resulting in defective protein in muscle fibres called dystrophin. lack of dystrophin --> no calcium enterting muscle |
|
signs and symptoms of DMD |
- weakness in proximal muscles , starting in lower extremeties. fine movements less affected ( fingers etc..) -difficulty walking, running, climbing stairs -use of hands to get up -delayed development -learning disability -dilated cardiomyopathy |
|
investigations and diagnosis |
- symptoms -CK- very high levels -muscle biopsy -genetic test |
|

|
acute dystonia |
- neurological movement disorder associated w/ muscle contractions result in twisting and repetitive movements or abnormal posture. can be induced by dopamine receptor blockers i.e haloperidol |
|
What is Lambert-Eaton Myasthenic Syndrome (LEMS) |
-Autoimmune disease -Affects neuromuscular Junction -immune system attacks ca+ channels which cause release of acetylcholine which causes muscle contraction ➡️muscles do not contract ➡️causes weakness -associated with small cell cancer |
