Hello! :)
In previous post, I discussed
about metabolic myopathies.
Today we see the general
classification of myopathies.
Myopathies are classified as
-CONGENITAL
-ACQUIRED
I. CONGENITAL:-
1. Denervation atrophy;-
-spinal muscular atrophy
(infantile motor neuron disease)
2. Muscular dystrophies
a) Autosomal recessive Muscular
dystrophy
-Limb-girdle form
b) Autosomal dominant muscular
dystrophy
-Facioscapulohumeral
-Occular
c) Sex linked muscular
dystrophy
-Duchene
-Becker
-Emery Dreifuss
3. Myotonic dystrophy
4. Ion channel myopathies
5. Congenital myopathies
6. Myopathies associated with inborn
errors of metabolism (This we have already studied in previous posts.)
II.ACQUIRED MYOPATHIES
1. Inflammatory myopathies
-Infectious
-non-Infectious
-systemic inflammatory disease
(involves other organs also)
2. Toxic myopathies
-Thyrotoxic myopathy (There is an awesome post By Ojas )

-Ethanol myopathy
-Drug induced myopathy
So this means, we have long way
to go: D
Myopathy means we are discussing problem in MUSCLES.
"MOTOR
ACTIVITY” is a broad term. It includes
1) Voluntary movements
2) Reflex movements
3) Rhythmic motor patterns
The pathway of any motor
activity includes:
1. Cortical level
2. Brainstem and associated
structures
-Brainstem centers
-Basal ganglia
-cerebellum
3. Spinal cord
4. Lower motor neurons
5. Neuromuscular junction
6. Muscle
So how do we know the correct
site of lesion?
To diagnose any myopathy, we
need to know its site and cause of lesion. The following helps in the diagnosis.
1. History
2. Examination
3. Investigations
