Clinical Testing and Workup Nerve conduction studies (NCS) and electromyography (EMG) are very useful.[rarediseases.org]
Since muscle wasting and sensory disturbance are the main features of these syndromes, treatments aim to improve motor impairment and sensory disturbances. Specific treatment trials are rare.[cochrane.org]
TREATMENT: There is no known pharmacological treatment to hereditary motor and sensory neuropathies. However, people with these diseases can walk and be self-sufficient.[alwaysayurveda.net]
Currently, no definitive treatment exists for HMSN. It cannot be stopped or reversed, but it can reach a point where the progression steadies itself.[aanem.org]
TO TOP What treatments are available? Currently, there is no known cure for HMSN/ACC or treatments to prevent the onset of symptoms.[muscle.ca]
It is only by knowing the natural history that one understands the onset of clinical symptoms, the rate of progression, and the ultimate prognosis of these diseases.[clinicaltrials.gov]
Prognosis [ edit ] Hereditary motor and sensory neuropathy are relatively common and are often inherited with other neuromuscular conditions, and these comorbidities cause an accelerated progression of the disease.[en.wikipedia.org]
CMT in pregnancy increases the risk for complications during delivery and a higher risk of intervention. [ 11 ] Prognosis This is dependent on subtype; clinical impairment and disability correlate with axonal loss: Most patients with CMT1A have normal[patient.info]
Treatment and prognosis Unfortunately no effective drug for CMT exists. Treatment is largely supportive with rehabilitation therapy and surgery for skeletal deformities 5.[radiopaedia.org]

Abstract Hereditary motor and sensory neuropathies (HMSN) is a complex group of diseases, mainly of unknown etiology.[ncbi.nlm.nih.gov]
Diagnostic tests, usually beginning electrodiagnostic testing, are indicated in patients with atypical clinical features, unknown etiology, and/or severe or rapidly progressive symptoms.[amboss.com]
Several demyelinating etiologies can produce a “Dejerine-Sottas” phenotype with early onset, palpable nerves, and marked onion-bulb formation.[now.aapmr.org]
(Etiology) The cause of Hereditary Sensory Neuropathy Type II is a recessive mutation in either the WNK1 gene on chromosome 12 (A), the FAM134B gene on chromosome 5 (B), the KIF1A gene on chromosome 2 (C), or in the SCN9A gene on chromosome 2 (D).[dovemed.com]
Abstract A clinical, genetic and epidemiological study of hereditary motor and sensory neuropathies (HMSN) was performed in the province of Turin, Italy. The patients were allocated to 5 groups, according to genetic and electroneurographic features.[ncbi.nlm.nih.gov]
Epidemiology It is the most common inherited neuromuscular disorder affecting 1 in 2,500 people. [ 1 ] It has no predilection for a particular race or sex.[patient.info]
