Duchenne Muscular Dystrophy
Duchenne Muscular Dystrophy
A severe form affecting mostly boys, with onset around age 2-6, often fatal by 20s due to progressive muscle loss.

Study Notes
Muscular Dystrophy
- A group of chronic disorders causing progressive weakness and wasting of skeletal muscles.
- Inherited, genetic counseling recommended.
- Muscle fiber degeneration and permanent loss.
Types of Muscular Dystrophy
- Duchenne: (2-6 years), muscle weakness affecting pelvis, upper arms/legs, usually not survival past 20s, males, sex-linked.
- Becker: (adolescents, early adulthood), similar symptoms to Duchenne, males, sex-linked.
- Congenital: (at birth), slow progression, weakness.
- Distal: (40-60 years), slow progression, weakness in arms, hands, and legs, rarely leads to total incapacity.
- Emery-Dreifuss: (childhood-early teens), slow progression, weakness in shoulders, arms, and shin muscles, death is often cardio related.
- Facioscapulohumeral: (childhood-early adulthood), slow but rapid decrease of facial muscle weakness, wasting of shoulders and arms, decades of life expectancy past onset.
- Limb-girdle: (late childhood to middle age), slow progression, weakness and wasting of shoulder and pelvic girdle, death is often cardio related.
- Myotonic: (20-40 years), weakness in muscle groups with delayed relaxation, slow progression (50-60 years).
- Oculopharyngeal: (40-70 years), muscle weakness in eyelids and throat, swallowing difficulty, extremely slow progression.
Clinical Symptoms
- Muscle wasting and weakness.
- Hypotonia (low muscle tone).
- Lack of coordination.
- Progressive crippling, muscle contractures.
- Loss of mobility.
- Spinal deformity.
- Progressive weakness (inheritable).
Gowers Maneuver
- Used to assess leg muscle weakness in children. They raise themselves from their knees to standing.
Symptom Management
- No specific cure.
- Medications:
- Corticosteroids (slow muscle degeneration).
- Anticonvulsants (control seizures).
- Immunosuppressants (slow cell damage).
- Antibiotics (resp infections.)
Important Information about Muscular Dystrophy
- Onset varies by type and gender.
- Spinal deformities are common; orthetic support may be needed.
- Pulmonary function can be compromised.
- Dental and speech problems can impact communication.
- Prognosis varies by type and progression.
- Genetic testing is essential.
- Risk of falls is increased.
Palliative and Hospice Care
- Palliative care: Quality of life management.
- Hospice care: Focuses on end of life.
- MAiD: Medical Assistance in Dying.

Description
This quiz covers the various types of muscular dystrophy, emphasizing their characteristics, progression, and genetic factors. Learn about Duchenne, Becker, congenital, distal, Emery-Dreifuss, facioscapulohumeral, and limb-girdle muscular dystrophies. Understanding these disorders is crucial for awareness and potential genetic counseling.
