Amyotrophy
Amyotrophy
Amyotrophy is a term used to describe thinning or wasting (atrophy) of musculature with attendant weakness. This may result from involvement of:
- Lower motor neurones (in which case fasciculations may also be present):
- Amyotrophic lateral sclerosis
Benign focal amyotrophy/monomelic amyotrophy Disinhibition-dementia-parkinsonism-amyotrophy complex (DDPAC)
Amyotrophic Creutzfeldt-Jakob disease (obsolete term) "Asthmatic amyotrophy" (Hopkins’ syndrome)
- Amyotrophic lateral sclerosis
- Nerve roots:
- Diabetic amyotrophy (polyradiculopathy, especially L2-L4)
- Plexus:
- Neuralgic amyotrophy (Parsonage-Turner syndrome)
Hence although the term implies neurogenic (as opposed to myogenic) muscle wasting, its use is nonspecific with respect to neuroanatomical substrate.
- Neuralgic amyotrophy (Parsonage-Turner syndrome)
